Abstract:
The present study aimed to evaluate some physiological variables of thin tailed sheep and Garutsheep fed by concentrate and mung bean sprout waste diet. The physiological variables includedrectal temperature, respiration rate, and heart rate. Six Javanese thin tailed sheeps (16.27±0.86kg) and six Garut sheeps (10.68±1.82 kg) which aged less a year were selected for 4 treatments byfactorial design 2 x 2. The first factor was diet (concentrate and bean sprout waste) and the secondfactor was kind of sheep (Javanese thin tailed sheep and Garut sheep). The sheep were fedindividually for a maintenance requirement on body weight. Ambient temperature, relativehumidity, and physiological variables were measured every morning before feeding during 8weeks. The result showed that the physiological response of Javanese thin tailed sheep and Garutsheep fed by concentrate and mung bean sprout waste diet showed no interaction (P>0.05). Thephysiological response of sheep was not significantly different but the feed treatments had asignificant effect (P>0.05). Rectal temperature, heart rate, and respiration rate were still classifiedas normal so the mung bean sprout waste diet can be used as an alternative source of protein tosubstitute concentrate.

Abstract:
1. Oxygen consumption and ouabain-sensitive respiration was measured for liver biopsies from lactating and non-lactating ewes and for hepatocytes isolated from mature, dry ewes. O2 consumption, ouabain-sensitive respiration and 86Rb+ uptake were also measured for hepatocytes isolated from lambs, fed adult sheep and adult sheep starved for 5 d.2. Ouabain-sensitive respiration in the liver of ewes at peak lactation accounted for 45% of the total liver O2 consumption. This percentage was 24–37% higher (P > 0.05) than measurements made during late lactation and during the non-lactating period.3. Total O2 consumption and ouabain-sensitive respiration rates of lamb hepatocytes were greater ( P > 0.05) than similar measurements for hepatocytes isolated from adult sheep.4. Ouabain-sensitive 86Rb+ uptake by hepatocytes from fed sheep was up to six times greater (P > 0.05) than that by cells from starved sheep.5. The magnitude of ouabain-sensitive respiration of hepatocytes from starved sheep was 62% lower (P > 0.05) than that for hepatocytes from fed sheep.

Abstract:
1. Oxygen consumption and Na+,K+-ATPase(EC 3.6.1.3)-dependent (ouabain-sensitive) and -independent respiration were measured for duodenal mucosa biopsies from 10-month-old sheep given two levels of digestible energy (DE) intake (7.6–7.7 and 14.8 MJ lucerne (Medicago sativa) pellets/d) and following 48 h of starvation.2. The mucosal biopsies were determined to be structurally intact and free of adherent bacteria on histological and scanning-electron-microscope examinations.3. The use of D-glucose as a substrate during incubations did not elevate (P > 0.05) the respiration indices of the biopsies over those measured during acetate incubations.4. Glucose uptake did not (P > 0.05) influence the Na+,K+-ATPase-dependent respiration of the mucosal biopsies.5. Na+,K+-ATPase-dependent respiration accounted for 50% of the total O2, consumption of the mucosal biopsies of sheep given the lower level of DE.6. Total O2, consumption of the duodenalmucosa was not (P > 0.05) increased when sheep were given the higher level of DE but Na+,K+-ATPase-dependent respiration of the mucosa was elevated (P < 0.01) by 37% during this period.7. When sheep were starved for 48 h, total O2, consumption of the mucosal biopsies was not (P > 0.05) affected, however, Na+,K+-ATPase-dependent respiration of the biopsies dropped (P < 0.01) by 45%.8. Na+,K+-ATPase-dependknt respiration accounted for 61.3% of the O2, uptakes of mucosa from the sheep given the higher level of DE and 28.3% of the 02, uptake of mucosa from fasted sheep.

Abstract:
The object of the present study was to determine the effect of thyroxine (T4) treatment of sheep on protein synthesis and associated energy costs in skeletal muscle and hepatocytes. Protein synthesis, and ouabain-sensitive and cycloheximide-sensitive respiration in isolated intercostal muscle and hepatocytes were determined in sheep after 5 weeks of daily injections of either saline or T4. Plasma T4 and total triiodothyronine (T3) concentrations were doubled and free T3 concentrations were quadrupled by T4 injections. The fractional rates of protein synthesis increased in isolated external intercostal muscle and hepatocytes from hyperthyroid sheep. Fractional rates of protein synthesis in isolated external intercostal muscle and hepatocytes were linearly correlated with plasma free T3 concentrations. Total oxygen consumption of muscle and hepatocytes was unaffected by T4 injections. Ouabain-sensitive respiration increased in hepatocytes and muscle of T4-treated animals. Cycloheximide-sensitive respiration was elevated in hepatocytes from hyperthyroid sheep. Cycloheximide-sensitive respiration in muscle was unaffected by T4 treatment. The present experiment demonstrates that T4 increases protein synthesis in ruminants. The energy expenditure in support of Na+, K+-ATPase and protein synthesis in skeletal muscle and hepatocytes may account for 34–60% of total cellular energy expenditure.

Abstract:
Abstract. Previous work has failed to address fully the response of (autotrophic and heterotrophic) respiration to grazing in different ecosystems, particularly in alpine grasslands outside the growing season. From 2010 to 2011 a field experiment combined two methods (static closed chambers and a closed dynamic soil CO2 flux system) in alpine grasslands located in the Tianshan Mountains. We examined the effects of grazing regime on ecosystem respiration (Re) both outside (NGS) and during (GS) the growing season and determined the pattern of Re in relation to climate change. There was no significant change in CO2 emissions under grazing. Heterotrophic respiration (Rh) accounted for 78.5% of Re with short-term grazing exclusion and 93.2% of Re with long-term grazing exclusion. Re, Rh and autotrophic respiration (Ra) fluxes outside the growing season were equivalent to 12.9%, 14.1% and 11.4% of the respective CO2 fluxes during the growing season. In addition, our results indicate that soil water content played a critical role in Ra in the cold and arid environment. Both Rh and Re were sensitive to soil temperature. Moreover, our results suggest that grazing exerted no significant effect on CO2 emissions in these alpine grasslands.

Abstract:
Context Australia exports ~2 million sheep annually. On these voyages, sheep can be exposed to rapidly changing ambient conditions within a short time, and sheep may be exposed to periods of excessive heat load. Aims The aim of this study was to define the responses of sheep exposed to incremental heat load under simulated live export conditions. The study herein describes the influence of heat load on wool surface temperature, body temperature (rumen temperature (TRUM), °C; and rectal temperature (TREC), °C) and respiratory dynamics (respiration rate, breaths/min; and panting score (PS)) of sheep under live export conditions. In addition, the relationship between body temperature and respiratory dynamics was investigated. Methods A total of 144 Merino wethers (44.02 ± 0.32 kg) were used in a 29-day climate controlled study using two cohorts of 72 sheep (n = 2), exposed to two treatments: (1) thermoneutral (TN; ambient temperature was maintained between 18°C and 20°C), and (2) hot (HOT; ambient temperature minimum and maximum were 22.5°C and 38.5°C respectively). Sheep in the HOT treatment were exposed to heat load simulated from live export voyages from Australia to the Middle East. Respiration rate, PS and wool surface temperature (°C) data were collected four times daily, at 3-h intervals between 0800 hours and 1700 hours. Rectal temperatures were collected on five occasions at 7-day intervals. These data were evaluated using a repeated measures model, assuming a compound symmetry covariance structure. Individual TRUM were obtained via rumen boluses at 10-min intervals between Days 23 and 29 of Cohort 2. Individual TRUM data were collated and converted to an hourly mean TRUM for each sheep, these data were then used to determine the hourly mean TRUM for TN and HOT, then analysed using a first order autoregressive repeated measures model. Additionally, the relationship between respiratory dynamics and TRUM were investigated using a Pearson’s correlation coefficient, a partial correlation coefficient and a multivariate analysis of variance. Key results The respiration rate of the HOT sheep (140 ± 3.55 breaths/min) was greater (P &lt; 0.01) than that of the TN sheep (75 ± 3.55 breaths/min). Similarly, the PS of the HOT (1.5 ± 0.02) sheep was greater (P = 0.009) compared with the TN sheep (1.2 ± 0.02). Wool surface temperatures and TREC were greater (P &lt; 0.05) for the HOT sheep than for the TN sheep. There were treatment (P &lt; 0.0001), hour (P &lt; 0.0001), day (P = 0.038) and treatment × hour (P &lt; 0.0001) effects on the TRUM of TN and HOT sheep. Conclusions The climatic conditions imposed within the HOT treatment were sufficient to disrupt the thermal equilibrium of these sheep, resulting in increased respiration rate, PS, TREC and TRUM. Implications These results suggest that the sheep were unable to completely compensate for the imposed heat load via respiration, thus resulting in an increase in TREC and TRUM.

Abstract:
This study aimed to examine the relationship of feeding time on physiological response and the effect on the behavior of Javanese thin-tailed sheep. The total population of the study was 12 sheep. The treatment in this study is feeding time in the morning (W1) and evening (W2). Parameters that had been observed were heart rate, respiration rate, rectal temperature. This research design used was a completely randomized design. Feeding at different times did not affect daily body weight gain. However, feeding at different times affects the physiological response of thin tail sheep. W1 has a higher heart rate value at daytime of 80.65 ± 3.49 but has a lower value in the afternoon at 75.26 ± 4.20. Respiration rates W1 in the morning and evening were 32.06 ± 2.69 and 51.88 ± 3.43. Rectal temperature W1 lower in the morning at 37.76 ± 0.05. Physiological response of thin tail sheep which were fed with different feeding times indicated that the heart rate, respiration rate, and rectal temperature were still in normal condition.

Abstract:
Skeletal muscle from the late gestation sheep fetus with intrauterine growth restriction (IUGR) has evidence of reduced oxidative metabolism. Using a sheep model of placental insufficiency and IUGR, we tested the hypothesis that by late gestation, IUGR fetal skeletal muscle has reduced capacity for oxidative phosphorylation because of intrinsic deficits in mitochondrial respiration. We measured mitochondrial respiration in permeabilized muscle fibers from biceps femoris (BF) and soleus (SOL) from control and IUGR fetal sheep. Using muscles including BF, SOL, tibialis anterior (TA), and flexor digitorum superficialis (FDS), we measured citrate synthase (CS) activity, mitochondrial complex subunit abundance, fiber type distribution, and gene expression of regulators of mitochondrial biosynthesis. Ex vivo mitochondrial respiration was similar in control and IUGR muscle. However, CS activity was lower in IUGR BF and TA, indicating lower mitochondrial content, and protein expression of individual mitochondrial complex subunits was lower in IUGR TA and BF in a muscle-specific pattern. IUGR TA, BF, and FDS also had lower expression of type I oxidative fibers. Fiber-type shifts that support glycolytic instead of oxidative metabolism may be advantageous for the IUGR fetus in a hypoxic and nutrient-deficient environment, whereas these adaptions may be maladaptive in postnatal life.

Abstract:
Sheep is a small ruminant llivestock that area mostly raised by farmers in Indonesia fat tailed sheep (DEG) is one of the genetic resources of livestock that has economics, scientifics and socio-cultural values and has the potential; to be used to meet the needs of animal protein for humans. This study aimed to examine the effect of indigofera sp flour feeding on the physiological response of fat tail rams. The design used was a completely randomized design with the following treatments: control feed without administration of indigofera sp flour (P0), commercial feed + 10% Indigofera sp flour (P1), Commercial feed +20% Indigofera sp flour (P2). The treatments was given to male fat-tailed sheep with body weight (30 kg) and uniform age (1,5 years), healthy and not disabled. The variables observed were body temperature, respiration rate, heart rate, and feed consumption. The treatments of giving Indigofera sp flour to the ration was estimated to have a significant effect (respiration rate, heart rate and body temperature) from the normal limit compared to thr treatments of fat tail rams without administration of Indigofera sp flour.Key words: fat tailed sheep, Indigofera sp flour, physiological response

Abstract:
Many Caribbean small ruminant management systems are forage-based, relying on rain to sustain pastures for feed. Animal performance is thus heavily dependent on forage availability. The nutritive value of pasture was highest during the intermediate season and lowest during the dry season, leading to under nutrition, and declined flock performance in the dry season. Climate change will therefore seriously hamper pasture availability and nutritive value. Hair sheep on pasture, without shade or water, experienced increased respiration rate, they were under chronic heat stress. However, where adequate shade and water were provided, heat stress was reduced. The current system of small ruminant production is prone to the negative impacts of climate change events due to its effect on nutrition, growth and reproduction. Immediate actions are needed to prepare farmers to respond by mitigation methods, to maintain and enhance animal productivity if the envisaged protein security goals set for this sector are to be realized.
