Abstract:

Taking the strong built-in electric field into consideration, the optical-rectification (OR) coefficient in a nitride semiconductor coupling quantum well (CQW) has been theoretically investigated by using the compact density matrix approach. The electronic eigenstates in a nitride CQW are exactly solved based on the built-in electric field model already constituted in the recent reference. Numerical calculations on the typical GaN / InxGa1-xN CQW are performed. The calculated results reveal that the OR coefficients of the CQW are not monotonic functions of the well width, barrier width, and the doped concentration of the CQW systems but have complicated dependent relations on them. Our calculation shows that a strong OR effect can be obtained in the nitride CQW by choosing optimized structural parameters and a relatively low doped fraction.

Abstract:

Based on the density matrix approach and iterative treatment, the third-harmonic generation (THG) susceptibility of a wurtzite nitride coupling quantum well (CQW) with strong built-in electric fields have been theoretically investigated. The band non-parabolicity effect of nitride heterostructures has been taken into account. A typical wurtzite AlGaN/GaN CQW are chosen to perform numerical calculations. The result shows that, the THG coefficients sensitively depend on the structural parameters of the CQW system. Moreover, a strong THG process can be realized in the nitride CQW by choosing a group of appropriate structural parameters and doped fraction.

Abstract:

We show the formation of slow optical solitons in the asymmetric coupled double quantum wells (CQW) via a two-photon Raman resonance. With the consideration of real parameters in AlGaAs -based CQW, we indicate the possibility to have cancelation of the linear absorption, giant Kerr nonlinearities, and slow group velocity propagation of the weak probe pulse at the same one-photon detuning frequency around several THz .

Abstract:

Based on the density-matrix approach and iterative treatment, a detailed procedure for the calculation of the linear and nonlinear intersubband refractive index changes (RICs) in wurtzite GaN-based coupling quantum wells (CQWs) is given. The simple analytical formulas for electronic eigenstates and the linear and third-order nonlinear RICs in the systems are also deduced. Numerical result on a typical AlGaN / GaN CQW shows that the linear and nonlinear RICs sensitively depend on the structural parameters of the CQW system as well as the doped fraction of nitride semicondutor.

Abstract:

We propose and analyze an efficient scheme for suppressing the absorption of a weak probe field based on intersubband transitions in a four-level asymmetric coupled quantum well (CQW) driven coherently by a probe laser field and a control laser field. We study the steady-state process analytically and numerically, and our results show that the probe absorption can be completely eliminated under the condition of Raman resonance (i.e. two-photon detuning is zero). Besides, we can observe one transparency window without requiring one- or two-photon detuning to exactly vanish. This investigation may provide a possible scheme for EIT in solids by using the CQW.

Abstract:

ABSTRACTThe many-body correlation effects in the spatially separated electron and hole layers in the coupled quantum wells (CQW) are investigated. A special case of the many-component electron-hole system is considered, ν>>1 being the number of the components. Keeping the main diagrams in the parameter 1/ν allows us to justify the selection of the RPA diagrams. The ground state of the system is found to be the electron-hole liquid with the energy smaller than the dense exciton gas phase. The possible connection is discussed between the results obtained and the experiments in which the inhomogeneous state in the CQW is found.

Full text

Abstract:

A process-voltage-temperature (PVT)-robust, low power, low noise, and high sensitivity, super-regenerative (SR) receiver is proposed in this paper. To enable high sensitivity and robust-PVT operation, a fast locking phase-locked-loop (PLL) with initial random phase error reduction is proposed to continuously adjust the center frequency deviations of the SR oscillator (SRO) without interrupting the input data stream. Additionally, a concurrent quenching waveform (CQW) technique is devised to improve the SRO sensitivity and its noise performance. The proposed SRO architecture is controlled by two separate biasing branches to extend the sensitivity accumulation (SA) phase and reduce its noise during the SR phase, compared to the conventional optimal quenching waveform (OQW). The proposed SR receiver is implemented at 2.46 GHz center frequency in 180 nm SMIC CMOS technology and achieves better sensitivity, power consumption, noise performance, and PVT immunity compared with existent SR receiver architectures.

Abstract:

A theoretical investigation of optical properties of a cylindrical quantum wire (CQW) is presented. The properties studied were optical absorption coefficient (AC) and change in refractive index (CRI) of the quantum wire. In particular, effect of an inverse parabolic potential on the optical properties of CQWs was investigated. This was done by solving the Schrödinger equation within the effective mass approximation to obtain the wave functions. The inverse parabolic potential reduces transition energies and therefore redshifts peaks of the AC, as well as the anomalous dispersion region of the dependence of change in refractive index on the photon energy. The inverse parabolic potential also has effect on the magnitudes of these optical quantities, reducing the AC and enhancing the CRI. These properties of the inverse parabolic confining electric potential can have a wide range of applications in nanodevice technology, some details of which are discussed.

Abstract:

Abstract We design and demonstrate an asymmetric Ge/SiGe coupled quantum well (CQW) waveguide modulator for both intensity and phase modulation with a low bias voltage in silicon photonic integration. The asymmetric CQWs consisting of two quantum wells with different widths are employed as the active region to enhance the electro-optical characteristics of the device by controlling the coupling of the wave functions. The fabricated device can realize 5 dB extinction ratio at 1446 nm and 1.4 × 10−3 electrorefractive index variation at 1530 nm with the associated modulation efficiency V π L π of 0.055 V cm under 1 V reverse bias. The 3 dB bandwidth for high frequency response is 27 GHz under 1 V bias and the energy consumption per bit is less than 100 fJ/bit. The proposed device offers a pathway towards a low voltage, low energy consumption, high speed and compact modulator for silicon photonic integrated devices, as well as opens possibilities for achieving advanced modulation format in a more compact and simple frame.

Abstract:

Despite burgeoning researches on happiness in different fields of psychology, anthropology, and economics, in the west on Judeo-Christians and on men, fewer researches were conducted on correlates of happiness among Muslims especially Women in the African context. World happiness report (WHR) reported that Nigeria was ranked as the 5th happiest nation and 6th in Africa, however fewer researches of happiness in Nigeria were reported especially in Northern Nigeria. It investigated the relationship between happiness, culture, socio-economic status and religious coping, among Muslim women students. Quantitative design of the correlational type was used, the population of 900 students from women centers for continuing education (WCCE) and 269 samples using a purposive sampling method. Orientation to happiness scale (OHS) with the reliability of 0.953, cultural questionnaire for women (CQW) with a coefficient of 0.918, a demographic questionnaire socio-economic status scale (SESS) with 0.717 reliability co-efficient and Islamic religious coping scale (IRCOPE) with alpha 0.888 were the instruments used for data collection, generally named happiness, culture, socio-economic status and religious coping scale with a total coefficient of 0.937. Partial least square based on structural equation modelling (PLS-SEM) was used to analyse the data. It revealed that a statistically significant positive relationship between happiness, culture and religious coping, while SES was not significantly related to happiness among Muslim women students.

Abstract:

Centella asiatica (CA) is an edible plant and a popular botanical dietary supplement. It is reputed, in Ayurveda, to mitigate age-related cognitive decline. There is a considerable body of preclinical literature supporting CA’s ability to improve learning and memory. This study evaluated the contribution of CA’s triterpenes (TT), widely considered its active compounds, and caffeoylquinic acids (CQA) to the cognitive effects of CA water extract (CAW) in 5XFAD mice, a model of Alzheimer’s disease. 5XFAD mice were fed a control diet alone, or one containing 1% CAW or compound groups (TT, CQA, or TT + CQA) equivalent to their content in 1% CAW. Wild-type (WT) littermates received the control diet. Conditioned fear response (CFR) was evaluated after 4.5 weeks. Female 5XFAD controls showed no deficit in CFR compared to WT females, nor any effects from treatment. In males, CFR of 5XFAD controls was attenuated compared to WT littermates (p = 0.005). 5XFAD males receiving CQA or TT + CQA had significantly improved CFR (p < 0.05) compared to 5XFAD male controls. CFR did not differ between 5XFAD males receiving treatment diets and WT males. These data confirm a role for CQA in CAW’s cognitive effects.

Abstract:

The present results showed that cooling water (CLW) was more easy to be contaminated than the condensed water (CDW) of central aircondition by Legionella in high air temperature and humidity, and the Legionella was not observed in all sample of the cold medium water (CMW) of central aircondition. The air temperature and relative humidity have significant impact on Legionella. No sample was positive while the average relative humidity was lower than (77.08 ± 1.30) %, and the high value of the ratio of positive samples occurred while the average air temperature and the average relative humidity reached to (26.00 ± 0.35) oC and (85.15 ± 0.74) % respectively. It should be attached importance to the Legionella infection and Legionnaires’ disease prevalence resulted from central aircondition, and the cooling water and condensed water should be sterilized regularly for the prevention and control of Legionella disease.

Abstract:

Antibacterial peptides were isolated and purified from whey proteins of camel milk (CaW) and cow milk (CoW) and their antimicrobial activities were studied. The whey proteins were hydrolyzed using trypsin, and the degree of hydrolysis was identified by gel electrophoresis. The whey hydrolysate (WH) was purified using ultrafiltration and Dextran gel chromatography to obtain small peptides with antibacterial activity. The effect of the antimicrobial peptides on the morphology of bacterial strains was investigated using transmission electron microscopy. Their amino acid composition and antimicrobial activities were then determined. Polypeptides CaWH-III (<3 kDa) and CoWH-III (<3 kDa) had the strongest antibacterial activity. Both Fr.A2 (CaWH-Ⅲ’s fraction 2) and Fr.B1 (CoWH-Ⅲ’s fraction 1) had antibacterial effects toward Escherichia coli and Staphylococcus aureus, with minimum antimicrobial mass concentrations of 65 mg/mL and 130 mg/mL for Fr.A2, and 130 mg/mL and 130 mg/mL for Fr.B1, respectively. The highly active antimicrobial peptides had high amounts of alkaline amino acids (28.13% in camel milk Fr.A2 and 25.07% in the cow milk Fr.B1) and hydrophobic amino acids. (51.29% in camel milk Fr.A2 and 57.69% in the cow milk Fr.B1). This results showed that hydrolysis of CaW and CoW using trypsin produced a variety of effective antimicrobial peptides against selected pathogens, and the antibacterial activity of camel milk whey was slightly higher than that of cow milk whey.

Abstract:

During the ninth field season at the Late Bronze Age city of Hala Sultan Tekke, excavations in City Quarter 1 (CQ1) continued and brought to light industrial and domestic structures belonging to three phases of occupation (Strata 3–1) dating to the 13th and 12th centuries BC (LC IIC–IIIA). Finds of more than half a ton of copper slag together with remains of furnaces and tuyères indicate intensive urban copper production. There is also evidence of textile production in CQ1. A magnetometer survey of roughly 23 ha resulted in the discovery of another large city quarter (CQ4) between CQ1 and Area A (the cemetery) with regularly arranged stone-built compounds of imposing dimensions intersected by streets. Several massive walls are faced with ashlar slabs which distinguishes this quarter from the industrial and domestic CQ1–3. A bathroom built of ashlar blocks with an advanced hydrological layout was exposed in CQ4 (Stratum 1, LC IIIA) together with a storage area for large vessels. Another rich tomb (Tomb RR) was excavated in Area A. It contained multi-burials together with tomb gifts from numerous Eastern Mediterranean cultures. One of the finds from Tomb RR is a complete large Mycenaean krater depicting two chariots drawn by two pairs of horses and 13 individuals, several of them with swords.

Abstract:

209 Background: Providing patient-centred care is an essential component of high quality integrated care. Nowadays, patient reported outcomes and experiences are increasingly used to measure quality of care. As part of a quality registration, the Dutch Head and Neck Audit, patient reported outcomes (PROs) and experiences (PREs) of patients with head and neck cancer (HNC) are measured with questionnaires and evaluated to increase patient-centred care. Methods: Patientswere recruited from nine hospitals participating in the DHNA. Validated questionnaires were distributed at baseline, 3, 6 and 12 months follow-up. Included PROMs were EQ-5D-3L, EORTC QLQ-C30 and EORTC QLQ-H&N35. Included PREMs were Consumer Quality index for Oncologic care (CQO) and Radiotherapeutic care (CQR). CQO and CQR have similar domains with different questions. With descriptive analysis, ANOVA and mixed model analysis, differences over time and between treatment groups were analyzed. Results: Questionnaires were filled in by 238 patients. Pain decreased significantly at 6 and 12 months follow-up and dry mouth increased significantly at 3, 6 and 12 months follow-up compared to baseline. Sticky Salvia, problems with social eating and sense problems increased at 3 and 6 months follow-up, but were similar to the baseline score at 12 months follow-up. Pain and sticky saliva differed between radiotherapy and chemoradiotherapy or surgery and radiotherapy respectively (p ≤ 0.05). Regarding the CQO domain scores, all treatment groups differ significantly from each other (p ≤ 0.05). This was not regarding the CQR domain scores. Except for the domain Organisation, no differences between the CQO and CQR domain scores were found. Recognizing the emotional side of HNC (care) and intensifying guidance after the treatment period needs improvement. Conclusions: This study gives clues to improve healthcare according the experiences of the patient and we can predict more carefully the outcomes of the patients with different treatment types. PROMs according to the ICHOM criteria and PREMs are promising for measuring and improving quality and personalization of HNC care. However, the usage of two PREMs had no added value to evaluate and address points of improvement.

Abstract:

AbstractThe prenatal development of cattle has influence on productive performance throughout postnatal life. The number of muscle and fat cells that the animal will have throughout its life is determined in the foetal stage and is influenced by nutrition of the pregnant cow. A systematic review and meta-analysis was performed to evaluate the effect of different energy levels (total digestible nutrient, TDN) and crude protein (CP) supplied to pregnant cows on foetal weight at 4 (FW4) and 8 months (FW8) and calf birth weight (CBW). Four studies and six trials involving 170 animals were assessed for FW4; four studies, four trials and 156 animals for FW8 and 48 studies, 125 trials and 9053 animals for CBW. High heterogeneity across studies was presented in FW4 (I2 = 94.4%), FW8 (I2 = 91.08%) and CBW (I2 = 96.9%). Dietary TDN and CP levels did not influence FW4. The FW8 was reduced by 2.24 kg when cows were fed 100% of their CP and TDN requirements (I2 = 0%), relative to those fed 70% of their requirements during the first and second trimesters. The CBW was reduced by 0.45 kg (I2 = 96.9%) when cows were fed 130% of their CP requirements relative to other dietary CP levels. When cows were fed 140% of their TDN requirements, CBW decreased by 2.71 kg (I2 = 98.3%) relative to other TDN levels. Dietary energy or CP levels fed above the requirements to pregnant cows restrict foetal development and CBW.

Abstract:

The present study evaluates the digestion of cork boiling wastewater (CBW) through a biochemical methane potential (BMP) test. BMP assays were carried out with a working volume of 600 mL at a constant mesophilic temperature (35 °C). The experiment bottles contained CBW and inoculum (digested sludge from a wastewater treatment plant (WWTP)), with a ratio of inoculum/substrate (Ino/CBW) of 1:1 and 2:1 on the basis of volatile solids (VSs); the codigestion with food waste (FW) had a ratio of 2/0.7:0.3 (Ino/CBW:FW) and the codigestion with cow manure (CM) had a ratio of 2/0.5:0.5 (Ino/CBW:CM). Biogas and methane production was proportional to the inoculum substrate ratio (ISR) used. BMP tests have proved to be valuable for inferring the adequacy of anaerobic digestion to treat wastewater from the cork industry. The results indicate that the biomethane potential of CBWs for Ino/CBW ratios 1:1 and 2:1 is very low compared to other organic substrates. For the codigestion tests, the test with the Ino/CBW:CM ratio of 2/0.7:0.3 showed better biomethane yields, being in the expected values. This demonstrated that it is possible to perform the anaerobic digestion (AD) of CBW using a cosubstrate to increase biogas production and biomethane and to improve the quality of the final digestate.

Full text

Abstract:

The present study aimed to develop predictive models of calf birth weight (CBW) from liveweight (LW) data collected remotely and individually using an automated in-paddock walk-over-weighing scale (WOW). Twenty-eight multiparous Charolais cows were mated with two Brahman bulls. The WOW was installed at the only watering point to capture LW over five months. Calf birth date and weight were manually recorded, and the liveweight change experienced by a dam at calving (ΔLWC) was calculated as pre-LW minus post-LW calving. Cow non-foetal weight loss at calving (NFW) was calculated as ΔLWC minus CBW. Pearson’s correlational analysis and simple linear regressions were used to identify associations between all variables measured. No correlations were found between ΔLWC and pre-LW (p = 0.52), or post-LW (p = 0.14). However, positive associations were observed between ΔLWC and CBW (p < 0.001, R2 = 0.56) and NFW (p < 0.001, R2 = 0.90). Thus, the results suggest that 56% of the variation in ΔLWC is attributed to the calf weight, and consequently could be used as an indicator of CBW. Remote, in-paddock weighing systems have the potential to provide timely and accurate LW data of breeding cows to improve calving management and productivity.

Abstract:

The tenth season of excavations at the Late Bronze Age city of Hala Sultan Tekke was carried out in four areas: City Quarter 1 (CQ1), CQ4, City Wall 1 (CW1), and Area A (Tomb RR). The excavations in CQ1 provided additional information on the pre-LC IIIA occupation of the city. Stratum 3 which can be dated to the LC IIC (13th century BC) was further exposed. For the first time in the city even older phases, Strata 4 and 5, were found. These are tentatively dated to the LC I–II (15th to 14th century BC). In CQ4 numerous storage areas were exposed, which belong to a large compound. There is also evidence of production of textiles and purple dye. All remains can be associated to the most recent Stratum 1 and can be securely dated in the LC IIIA, i.e. the 12th century BC. A test trench (CW1) was opened up 150 m to the south-east of CQ4, in an area where the magnetometer survey indicated a possible city wall with moat. A c. 2.5 m-wide man-made construction consisting of small stones intermingled with larger blocks of stones was found running north–south. Built against the interior of this structure is a copper-producing workshop as indicated by much slag, ash, and remains of a furnace, which is preliminarily dated to the 13th century BC. Tomb RR, which was partly excavated in 2018 and secured, was reopened and additional burials came to light. The total number of skeletons now stands at 37; these are associated with 74 complete/intact finds of mainly pottery vessels of which some contained food remains. The pottery comprises Cypriot-produced wares and Mycenaean imports, which indicate a LC IIB–C date of the burials. Other finds include a unique Minoan female figurine and a bronze knife with ivory handle.

Abstract:

The present study aimed to provide scientific information for the effect of somatic cells count (SCC) of raw cow milk on the fermentation process and quality characteristics of ayran. Test ayran samples were produced from three different batches of cow milk with low (<400,000 cells.cm-3), medium (between 500,000 and 600,000 cells.cm-3) and high (1000,000 cells.cm-3) SCC, respectively. The main physicochemical parameters as pH, total solids, milk fat, protein, lactose, lactic acid content and microbiological parameters as somatic cells count (SCC) and total viable count (TVC) of raw milk and ayran samples were studied. During the first coagulation stages, the higher SCC in the milk seems to have an inhibiting effect on the development of the lactic acid bacteria from the starter culture and on the fermentation process, respectively. Nevertheless, SCC of the raw milk did not have a significant effect on the composition of the ayran. The increase in the SCC values up to 1000,000 cells.cm-3 in the raw cow’s milk affected negatively the organoleptic characteristics of the ayran made from it. Practical applications:The knowledge for the effect of SCC of raw caw milk on the fermentation process allows us to optimize the technology parameters for production of ayran and to improve its quality characteristics. The data from sensory analysis of ayran samples produced by milks with different SCC will provide additional information for the importans of the implementation of the monitoring of somatic cells in raw caw milk quality control.

Abstract:

AbstractThe cotton-wheat double-cropping system is widely used in the Yellow River Valley of China, but whether and how different planting patterns within cotton-wheat double-cropping systems impact heat and light use efficiency have not been well documented. A field experiment investigated the effects of the cropping system on crop productivity and the capture and use efficiency of heat and light in two fields differing in soil fertility. Three planting patterns, namely cotton intercropped with wheat (CIW), cotton directly seeded after wheat (CDW), and cotton transplanted after wheat (CTW), as well as one cotton monoculture (CM) system were used. Cotton-wheat double cropping significantly increased crop productivity and land equivalent ratios relative to the CM system in both fields. As a result of increased growing degree days (GDD), intercepted photosynthetically active radiation (IPAR), and photothermal product (PTP), the capture of light and heat in the double-cropping systems was compared with that in the CM system in both fields. With improved resource capture, the double-cropping systems exhibited a higher light and heat use efficiency according to thermal product efficiency, solar energy use efficiency (Eu), radiation use efficiency (RUE), and PTP use efficiency (PTPU). The cotton lint yield and biomass were not significantly correlated with RUE across cropping patterns, indicating that RUE does not limit cotton production. Among the double-cropping treatments, CDW had the lowest GDD, IPAR, and PTP values but the highest heat and light resource use efficiency and highest overall resource use efficiency. This good performance was even more obvious in the high-fertility field. Therefore, we encourage the expanded use of CDW in the Yellow River Valley, especially in fields with high fertility, given the high productivity and resource use efficiency of this system. Moreover, the use of agronomic practices involving a reasonably close planting density, optimized irrigation and nutrient supply, and the application of new short-season varieties of cotton or wheat can potentially enhance CDW crop yields and productivity.

Abstract:

The production of biogas from livestock waste manure in particular is one of the alternative utilization of organic wastes that can be implemented in Indonesia since there is a huge potential of bio-energy in Indonesia. This study utilizes cow manure as the raw material for making biogas and it is coupled with a cow rumen fluid and water. The objective of this study is to determine the effect of manure, rumen, and water composition in biogas production. The research was conducted in anaerobic for 60 days. The composition of manure, water, and the rumen were vary following the variable and ratio; variable A (manure and water); variable B (manure and rumen). The results indicate that the variable A (manure and water) with a 1:3 ratio, and the variable B (manure and rumen) with a 1:2 ratio produced the highest volume of biogas compared to other ratios. The highest biogas production occurred on average at day 23.

Abstract:

6570 Background: Providing patient-centred care is an essential component of high quality integrated care. A method to get insight in patients perspectives about the quality of health care they received, is measuring Patient Reported Outcome Measures (PROMs) and Patient Reported Experience Measures (PREMs). We aimed to determine the outcomes of, and differences between PROs and PREs over time and between treatment groups for patients with head and neck cancer (HNC). Methods: Patientswere recruited from nine hospitals participating in the DHNA. Validated questionnaires were distributed at baseline, 3, 6 and 12 months follow-up. Included PROMs were EuroQol 5 Dimension 3 Level (EQ-5D-3L), EORTC QLQ-C30 and -H&N35. Included PREMs, Consumer Quality index for Oncologic care (CQO) and Radiotherapeutic care (CQR), have similar domains with different questions. With descriptive analysis, ANOVA and mixed model analysis, differences over time and between treatment groups were analyzed. Results: Questionnaires were filled in by 426 patients. Pain decreased significantly at 6 and 12 months follow-up (14 and 21 points on a scale of 0-100) and dry mouth increased significantly at 3, 6 and 12 months follow-up compared to baseline (35, 27 and 20 points). Sticky Salvia, problems with social eating and sense problems increased at 3 and 6 months follow-up, but were similar to the baseline score at 12 months follow-up. Pain and sticky saliva differed between radiotherapy and chemoradiotherapy or surgery and radiotherapy respectively (p≤0.05). Regarding the CQO domain scores, all treatment groups differed significantly from each other (p≤0.05), especially for the domain Personal input. There was no difference regarding the CQR domain scores. Recognizing the emotional side of HNC and guidance after the treatment scored low in patients. Conclusions: This study gives clues to improve healthcare according the experiences of the patient and we can predict more carefully the outcomes of the patients with different treatment types. PROMs according to the ICHOM criteria and PREMs are promising for measuring and improving quality and personalization of HNC care. However, recognizing the emotional side of HNC and intensifying guidance after the treatment period needs improvement.

Abstract:

In this paper, we compare the branching ratio and rate difference of electron channel to muon channel of [Formula: see text] and B →K*ℓ+ℓ- decays, where [Formula: see text] is the p-wave scalar meson, in the supersymmetric models. MSSM with R parity is considered since considerable deviation from the standard model predictions can be obtained in B→Xs ℓ-ℓ+. Taking CQ1 and CQ2 about one which is consistent with the B→K*μ+μ- rate at low dileptonic invariant mass region (1 ≤ q2 ≤ 6 GeV 2). It is found that, firstly, the [Formula: see text] decay is measurable at LHC, secondly, in comparison with B →K*ℓ+ ℓ- decay a greater deviation in the [Formula: see text] decay can be seen. Measurement of these observables for the semileptonic rare [Formula: see text], in particular, at low q2 region can give valuable information about the nature of interactions within Standard Model or beyond.

Abstract:

AbstractIn this research communication we describe the performance of dairy cow−calf pairs in two cow-driven CCC-systems differing in cows' access to the calves through computer-controlled access gates (smart gates, SG). We investigated cows' machine milk yield in the automatic milking system (AMS), calf growth, and intake of supplemental milk and concentrate. Two groups each with four cow-calf pairs were housed in a system with a cow area, a calf creep and a meeting area. SG's controlled cow traffic between the meeting area and the cow area where cows could obtain feed, cubicles and the AMS. Calves hadad libitumaccess to supplemental milk and concentrate. During the suckling phase of 31 d, cow access to the meeting area was free 24 h/d (group 1) or restricted (group 2) based on milking permission. Following the suckling phase, cow access was gradually decreased over 9 d (separation phase). During the suckling phase, cows' machine milk yield (mean ±sd) in the AMS was 11.4 ± 6.38 kg/d. In the separation phase, the yield increased to 25.0 ± 10.37 kg/d. Calf average daily gain (ADG) was high during the suckling phase: 1.2 ± 0.74 kg. During the separation phase, ADG decreased to 0.4 ± 0.72 kg which may be related to a low intake of supplemental milk. Calves' concentrate intake increased with age, and all calves consumed >1 kg/d after separation. We conclude that cows nurse the calf in a cow-directed CCC system well resulting in high ADG, and AMS milk yields were, at least, partially maintained during the suckling phase. Although the AMS yields increased in response to separation, calf ADG was decreased. A low sample size limits interpretation beyond description but provides a basis for hypotheses regarding future research into CCC-systems.
