Resumo: Anaplasma marginale é uma bactéria intraeritrocítica obrigatória do gênero Anaplasma, conhecida por causar anaplasmose bovina. Encontra-se distribuída em todo o mundo e causa grandes perdas econômicas nas indústrias de carne bovina e láctea. A. marginale foi descrita em muitas espécies. No entanto, os estudos envolvendo o diagnóstico sorológico de A. marginale em pequenos ruminantes são escassos. Até o presente momento, esta bactéria nunca foi detectada molecularmente em caprinos (Capra hircus). Assim, este estudo teve como objetivo estimar a prevalência de A. marginale e fatores associados à infecção em caprinos do Estado da Paraíba, no Nordeste do Brasil. O DNA de amostras de sangue de caprinos foi extraído e avaliado por uma reação em cadeia da polimerase convencional (cPCR) para a detecção da proteína de superfície 4 (major surface protein 4, msp4) de A. marginale. As amostras positivas foram posteriormente submetidas a cPCR para os genes msp5 e msp1? de A. marginale e sequenciados pelo método de Sanger. Onze de 403 cabras (2,73%; IC 95%: 1,53- 4,82%) foram positivas para o gene msp4 de Anaplasma. O sequenciamento do gene msp5 revelou a presença de A. marginale sensu stricto. Os caprinos infestados por carrapatos foram seis vezes mais propensos a estarem infectados com A. marginale (P = 0,02788). Amblyomma parvum (49/52, 94,23%) e Rhipicephalus microplus (3/52, 5,77%) foram as espécies de carrapatos identificadas parasitando os animais. Todas os caprinos positivos para A. marginale foram encontrados em fazendas com pastagem de múltiplas espécies (P = 0,04). O gene msp1? foi sequenciado encontrando o genótipo F nos animais estudados. Este é o primeiro relato molecular de infecção por A. marginale em caprinos. Além disso, descrevemos pela primeira vez o genótipo F no Brasil. Este estudo fornece a primeira informação sobre a infecção por A. marginale em cabras do Estado da Paraíba, no Nordeste do Brasil. Também demonstra que os caprinos podem desempenhar um papel na epidemiologia desta bactéria como um reservatório ainda não reconhecido. Carrapatos competentes que se alimentam de caprinos e bovinos podem transferir o patógeno entre as duas espécies de ruminantes.

Abstract: Anaplasma marginale is an obligate intraerythrocytic bacterium in the genus Anaplasma, known for causing bovine anaplasmosis. It is distributed worldwide and causes extensive economic losses in the beef and dairy industries. A. marginale has been described in many species; however, studies involving the diagnosis of A. marginale in small ruminants are scarce. To date, this bacterium has never been molecularly detected in goats (Capra hircus). Thus, this study aimed to estimate the prevalence of A. marginale and factors associated with the infection in goats from the State of Paraíba, northeastern Brazil. DNA from goat blood samples were extracted and screened by a conventional PCR (cPCR) assay for the detection of A. marginale major surface protein 4 (msp4). Positive samples were further submitted to cPCR assays for A. marginale msp5 and msp1? genes, and sequenced by Sanger method. Eleven out of 403 goats (2.73%; CI 95%: 1.53-4.82%) were positive for the Anaplasma msp4 gene. Sequencing of the msp5 gene revealed the presence of A. marginale sensu stricto. Tick-infested goats were six times more likely to be infected with A. marginale (P = 0.02788). Amblyomma parvum (49/52, 94.23%) and Rhipicephalus microplus (3/52, 5.77%) were the tick species identified feeding on the goats. All A. marginale-positive goats were found on farms with multispecies grazing (P= 0.04). The msp1? gene was sequenced and found the A. marginale genotype F in studied infected goats. This is the first molecular report of A. marginale infection in goats. Additionally, we describe for the first time the genotype F in Brazil. This study gives the first insight into A. marginale infection in goats from Paraíba State, northeastern Brazil and demonstrates that goats may play a role in the epidemiology of this bacterium as a yet unrecognized reservoir. Competent ticks feeding on goats and cattle may transfer the pathogen between the two livestock species. KEY WORDS: bovine anaplasmosis, goats, genotyping, small ruminants, PCR

Full textBody measurements have been used in animals to estimate body weight especially in rural areas where scales are not readily available. The study was conducted in Sekhukhune District of the Limpopo province, South Africa where the goats between the ages of 20 and 30 months were used. Body weight and four morphological traits were taken on each goat in the morning before they were released for grazing in a total of 613 indigenous goats of both sexes (62 male and 551 female). Body weight was measured in kilogram (kg) using a balance scale, hip height and shoulder height measurement (cm) were done using a graduated measuring stick and the body length and heart girth were measured in centimetre (cm) using a tape rule. Means, standard deviations (SD) and coefficients of variation (CV) of body weight and morphological traits were calculated. Pair wise correlations among body weight and morphological traits were also determined and range from 0.81-0.91 for male and 0.72-0.89 for female goats, respectively and were significant (P<0.01). The direct effect of heart girth on body weight was the strongest in both sexes (path coefficient of 0.58 and 0.62 in males and females, respectively). Body length (males) and body length and hip height (females) also positively (P<0.05) influenced body weight. The direct effects of other linear type traits on body weight in both sexes were non-significant as revealed by t-test. These traits were indirectly realized mostly via heart girth. Thus, they were removed from the final regression equations to obtain much more simplified prediction models. The optimum multiple regression equation for male goats included heart girth and body length, In female goats, however, the v variables included in the final prediction model were heart girth, body length and shoulder height. The forecast indices obtained in this study could aid in weight estimation, selection and breeding programmes.

O primeiro estudo avaliou TMR de partículas e líquido de cabritos Saanen em crescimento de diferentes sexos e submetidos a diferentes níveis de restrição alimentar. Foram utilizados 54 cabritos da raça Saanen (18 fêmeas, 18 machos castrados e 18 machos inteiros) em um arranjo fatorial 3 × 3 que compreendeu os três sexos e três níveis de restrição alimentar (ad libitum / sem restrição, restrição moderada e severa).

Os efeitos do sexo e interação entre sexo e restrição alimentar não foram significativos na maioria das variáveis avaliadas. A restrição alimentar aumentou o TMR de partículas e fluído.

The main objective was to assess the contribution of different segments of the gastrointestinal tract (GIT) to the fiber digestion. Two experiments were conducted, which mean retention time (MRT) of particulate and liquid matter, pool size, and tissues weight in different segments were determined by slaughter technique. The study one evaluated MRT of particulate and liquid matter in growing Saanen goats of different sexes and subjected to different levels of feed restriction. Fifty-four Saanen goats (18 each of females, castrated males and intact males) were used in a 3×3 factorial arrangement comprising the three sexes and three levels of feed restriction (unrestricted/ad libitum, moderate and severe restriction). Polynomial contrasts were used to determine linear and quadratic effect of feed restriction, while the effect of sex was compared by Tukey test. The effects of sex and the interaction between sex and feed restriction were not significant on most of variables evaluated. In conclusion, the level of feed restriction increased the MRT of particulate and liquid matter. The MRT was an important mechanism to increase nutrient supply when animals were subjected to feed restriction, as indicated by increased total tract digestibility. The second study examined physiological aspects in the digestion of fiber, particulate and liquid matter residence, pool size, and tissues weight in the whole tract of growing Saanen goats. A total of 58 Saanen goats were disposed in a 3×3 factorial arrangement consisting of three sexes (female, castrated males, intact males) and three slaughter weights (target BW 16, 23, and 30 kg at slaughter).

ENGLISH ABSTRACT: Different synchronization and superovulation treatments were evaluated in the South African Boer goat (n = 367). Two progestagen implants, Synchro-Mate-B (SMB)/Crestar™ and Controlled Internal Drug Releases (CIDR), containing 3mg norgestomet and 0.33gm of natural progesterone, respectively, were used in the synchronization treatments. A luteolytic agent, Estrumate (Cloprostenol) 125)lg, was administered 12h before progestagen withdrawal. Synchronization treatment groups were: 1) 5MB x 1 (n = 123), one dose of 5MB for 13 to 17 days; 2) 5MB x 2 (n = 32), two doses of 5MB implanted for 10then 17 days; 3) CIDR x 1 (n = 187), one dose of CIDR; 4) CIDR x 2 (n = 25), two doses of CIDR, inserted for 9 to 17 days. On day 1 of the treatment, 0.5mg of estradiol cypionate (ECP) was administered to a group of randomly chosen goats (n = 112). Superovulation treatments consisted of Ovagen ™ or Embryo-STM. An additional single dose (300 UI) of Pregnant Mare Serum Gonadotropin (PMSG) was administered to a group of randomly chosen does. Superovulation treatment groups were: 1) OV alone (n = 147), Ovagen 9 mg every 12h, 8 times starting 72h prior to progestagen removal; 2) OV + PMSG (n = 164), same treatment as 1 plus 300 ru ofPMSG once 48h prior to progestagen removal; 3) E-S alone (n=16), Embryo-S 25 units twice a day, 8 times starting 72h before progestagen removal; 4) E-S + PMSG (n=40), same treatment as 3 plus 300 ru of PMSG once 48h prior to progestagen removal. Most does were naturally bred to bucks. Embryos were collected using the surgicallaparascopic procedure on day 6 and corpora lutea counted. Data were not normally distributed and therefore analyzed using a nonparametrie test (Wilcoxon, 1945 and Kruskal- Wallis, 1952) with outcome variable using the Mixed Procedure of SAS and the Tukey test. Differences were considered significant at p<0.05. Slightly more CL were on the left (52%) than on the right (48%) ovary. Superovulation treatment was significantly associated (p

Full textThis dissertation draws on recent historical-critical research into ancient Jewish temple theology, the priestly book of Leviticus, and especially the Yom Kippur liturgy of Leviticus 16, to develop a more paradoxical interpretation of Christ?s saving work for modern Christian systematic theology. Prompted by the pioneering research of Jacob Milgrom, there has been a surge in sympathetic interpretations of the priestly theological tradition, which has inspired fresh interpretations of the Levitical Day of Atonement. I argue that an adequate Christian theory of atonement must be attentive to both the overall ?landscape? of Jewish biblical thought, and to the specific rhythm of the Yom Kippur liturgy, which clearly distinguishes the ?work? of two goats?one elected to be a spotless sacrifice, the other called to bear the sins of Israel into the wilderness. Christian theology should observe this distinction within the united saving work of Jesus Christ. Yet modern interpretations of the cross often implicitly emphasize one ?goat? or the other. For example, we find a ?goat for the Lord? soteriology in the Anselmian satisfaction tradition, which has been beautifully rearticulated by David Bentley Hart; here Christ?s spotless sacrificial obedience recapitulates creation done well. In the controversial ?descent to hell? theology of Hans Urs von Balthasar, on the other hand, there is a ?goat for Azazel? soteriology; here Christ as the sin-bearing goat removes impurity to the furthest possible distance from the Father through his saving descent. By seeing Christ as fulfilling the work of both goats in his single act of cruciform love, the Catholic tradition can better draw on the ancient Jewish insight that atonement requires a unifying movement toward the center, to the holy of holies, as well as a removal of sin to the far periphery, the godforsaken exilic wilderness. This work is rooted in the conviction that, first, Christian theology should always honor, and remain in deep conversation with, its Jewish roots, and second, that advances in historical-critical research should be utilized to cultivate a modern theological interpretation of scripture, all in the service of a richer, more ecumenical understanding of the basic paradoxes of Catholic soteriology.

Resumo: Objetivou-se determinar as exigências de Ca, P, Mg, K e Na em machos inteiros, machos castrados e fêmeas da raça Saanen. Foram realizados dois experimentos: um para determinar as exigências líquidas para mantença (Exp. 1) e outro para determinar as exigências líquidas para crescimento (Exp. 2). Setenta e cinco caprinos (26 machos inteiros, 25 machos castrados e 24 fêmeas) foram utilizados para determinar as exigências líquidas para mantença. Desses, 21 caprinos (8 machos inteiros, 7 machos castrados e 6 fêmeas) foram abatidos com peso médio de 16,6 ± 0,40 kg e foram utilizados como grupo referência para estimar a composição corporal inicial. Os 54 caprinos restantes (18 machos inteiros, 18 machos castrados e 18 fêmeas) foram alocados em seis blocos ao acaso, no quais foram incluídos três caprinos do mesmo sexo distribuídos em um dos três níveis de alimentação: ad libitum e ingestão de 75% ou 50% em relação aos animais alimentados ad libitum. Quando os animais alimentados ad libitum atingiram 30 kg de PC foram abatidos juntamente com os outros caprinos do mesmo grupo. Os dados das categorias sexuais e dos níveis de alimentação foram analisados em parcelas subdivididas. A parcela principal foi composta pelas três categorias sexuais e as subparcelas pelos três níveis de alimentação. Os requerimentos líquidos para mantença não diferiram entre as categorias sexuais (P > 0.05), resultando em valores de: 35,4 mg de Ca; 24,7 mg de P; 2,5 mg de Mg; 5,0 mg de K e 3,3 mg de Na/kg PC·d. ...

Abstract: Our study estimated Ca, P, Mg, K, and Na requirements of intact male, castrated male, and female Saanen goats. Two experiments were performed: one to determine the net macromineral requirements for maintenance (Exp. 1), and another to determine net macromineral requirements for growth (Exp. 2). In Exp. 1, 75 goats (26 intact males, 25 castrated males, and 24 females) with initial BW (iBW) of 15.76 ± 0.10 kg were used. These animals were divided in two groups: baseline animals and pair-fed animals. Twenty-one goats (8 intact males, 7 castrated males, and 6 females) were slaughtered at the beginning of the experiment (16.6 ± 0.40 kg BW) to be used as the baseline group. The 54 remaining goats (18 intact males, 18 castrated males, and 18 females) were pair-fed in 6 blocks of 3 goats per sex. The goats within each block were then randomly allocated to one of 3 different levels of intake: ad libitum, restricted-fed to 75% of the ad libitum intake, and restricted-fed to 50% of ad libitum intake. When the animal fed ad libitum reached 31.2 ± 0.58 kg BW, it and the other goats from the same block were slaughtered. The effects of sex and level of intake were evaluated in a split-plot design, where sex was the main plot observation and level of intake was the sub-plot. Daily net macromineral requirements for maintenance did not differ among the sexes (P > 0.05), and the average values obtained were 35.4 mg Ca, 24.7 mg P, 2.5 mg Mg, 5.0 mg K, and 3.30 mg Na per kg BW.

Resumo: Este trabalho foi realizado utilizando informações de 7 estudos, em que foram ajustadas curvas de crescimento ao desenvolvimento dos órgãos do sistema visceral de fêmeas, machos castrados e machos inteiros da raça Saanen de 0,5 a 19,5 meses de idade. Inicialmente, foram avaliados oito modelos: Regressão linear simples; Quadrático; Monomolecular; Brody; Von Bertalanffy; Logística; Gompertz; e Richards. Os dados dos órgãos viscerais (fígado, pâncreas, baço, rúmen-retículo, omaso, abomaso, intestino delgado e intestino grosso) e tecido adiposo mesentérico (TAM), foram ajustados nos modelos usando o procedimento NLMIXED do SAS. O melhor modelo ajustado foi escolhido com base no Critério de Informações Akaike corrigido para pequenas amostras (AICc) e nos coeficientes de correlação de concordância (CCC). Após a escolha do modelo que melhor ajustou a curva de crescimento dos órgãos viscerais avaliados, modelamos a variância buscando um melhor ajuste. Os parâmetros dos modelos para cada sexo foram comparados utilizando o comando CONTRAST (p < 0,10). Em geral, o modelo que melhor descreveu o crescimento de órgãos do sistema visceral foi o logístico (menor AICc e maior CCC). Quando os órgãos foram expressos em gramas, o sexo não influenciou os parâmetros das equações para predição do crescimento dos órgãos avaliados (p > 0,10), exceto o MAT (p < 0,02); em que as fêmeas apresentaram menor taxa de deposição comparada aos machos inteiros e castrados (0,318 ± 0,034 vs 0,659 ± 0,062), e um ...

Abstract: This work was performed gathering information of 7 studies, in which growth curves were fitted to the visceral organs of female, intact male, and castrated male Saanen goats from 0.5 to 19.5 months old. Initially, eight models were assessed: Monomolecular; Simple linear regression; Quadratic; Monomolecular; Brody; Von Bertalanffy; Logistics; Gompertz; and Richards. Data of the visceral organs (liver, pancreas, spleen, rumen-reticulum, omasum, abomasum, small intestine, and large intestine) and mesenteric adipose tissue (MAT) were fitted in the models using NLMIXED procedure of SAS. The best fitted model was choosing based on the Akaike Corrected Information Criterion for small samples (AICc) and values and the concordance correlation coefficient (CCC). After choosing the model that best fitted the growth curve of the evaluated visceral organs, we modelled the variance seeking a better fit. Parameters of the models for each sex were compared using the CONTRAST statement (p < 0.10). Overall, the model that best described visceral organ growth was the logistic (i.e., lower AICc and higher CCC). When organs were expressed in grams, the sex did not influence the parameters of equations to predict the growth of the evaluated organs (p > 0.10), except for TAM (p < 0.02); females presented a lower deposition rate compared to intact males and castrated males (0.318 ± 0.034 vs 0.659 ± 0.062), and a inflection point higher than intact males and castrated males (7.65 vs 3.69 months). However, this difference between the sexes is not found when TAM is expressed in % to empty body weight (EBW). Irrespective of sex, at the beginning of growth, liver stood for 2.75 ± 0.113 % of EBW, grew (g) at a maximum rate of 0.531 ± 0.062, and its inflection point of the curve occurred at 1.7 months.

Quando os órgãos foram expressos em gramas, o sexo não influenciou os parâmetros das equações para predição do crescimento dos órgãos avaliados (p > 0,10), exceto o MAT (p < 0,02); em que as fêmeas apresentaram menor taxa de deposição comparada aos machos inteiros e castrados (0,318 ± 0,034 vs 0,659 ± 0,062), e um ponto de inflexão superior ao dos machos inteiros e castrados (7,7 vs 3,7 meses). No entanto, essa diferença entre os sexos não é encontrada quando o MAT é expresso em % ao peso do corpo vazio (PCV). Independentemente do sexo, no início do crescimento, o fígado representou 2,75 ± 0,113 % do PCV, cresceu (g) a uma taxa máxima de 0,531 ± 0,062, e o ponto de inflexão de sua curva ocorreu em 1,7 meses. O trato gastrointestinal (TGI) representou 9,14 ± 0,493 % PCV, e à medida que os animais cresceram o TGI diminuiu sua porcentagem em relação ao PCV a uma taxa constante de 0,135 ± 0,046 %. Considerando o período avaliado, em geral, o rúmen-retículo e o intestino grosso aumentaram sua porcentagem em relação ao PCV e TGI, enquanto o abomaso e o intestino delgado diminuíram sua porcentagem em relação ao PCV e TGI, à medida que o animal crescia. O rúmen-retículo e o intestino grosso, que estão diretamente relacionados à digestão de alimentos sólidos, apresentaram maiores taxas de crescimento nos dois primeiros meses de vida. Os resultados evidenciaram que o sexo não afeta o crescimento de órgãos do sistema visceral (g), exceto para MAT, porém, quando olhamos em % PCV alguns órgãos mostram diferenças entre os sexos, como o fígado, abomaso, intestino delgado, intestino grosso e intestinos. O conhecimento da curva de crescimento dos órgãos viscerais pode ser muito útil para melhorar a compreensão de seu impacto sobre as exigências nutricionais desses animais, e ser utilizado para otimizar ou desenvolver um plano nutricional adequado para cada fase de crescimento, como também auxiliar os produtores a desenvolver planos estratégicos em um rebanho de caprinos, como a melhor idade para desmame e abate desses animais.

However, this difference between the sexes is not found when TAM is expressed in % to empty body weight (EBW). Irrespective of sex, at the beginning of growth, liver stood for 2.75 ± 0.113 % of EBW, grew (g) at a maximum rate of 0.531 ± 0.062, and its inflection point of the curve occurred at 1.7 months. The gastrointestinal tract (GIT) stood for 9.14 ± 0.493 % EBW, and as the goats grew the GIT decreased its percentage in relation to the EBW at a constant rate of 0.135 ± 0.046 %. Considering the evaluated period, in general rumen-reticulum and large intestine increased their percentage in relation to EBW and GIT, whereas abomasum and small intestine decreased their percentage in relation to EBW and GIT, as animal grew. The rumen-reticulum and large intestine, which are directly related to the digestion of solid foods, presented higher growth rates in the first two months of life. The results highlighted that sex does not affect the growth of visceral organs (g), except for TAM. However, when we look at % EBW, some organs show differences between the sexes, such as the liver, abomasum, small intestine, large intestine and Intestines. Knowledge of the growth curve of the visceral organs can be very useful in improving the understanding of their impact on the nutritional requirements of these animals and can be used to optimize or develop a nutritional plan suitable for each growth phase, but also to help producers develop strategic plans for a herd of goats, such as the best age for weaning and slaughtering these animals.

Abstract: The objective of this study was to evaluate the effect of sex on the net macromineral requirements for maintenance and growth of Saanen goats from 5 to 45 kg body weight (BW). For this purpose, three dataset were used: the first dataset was assembled to evaluate the effect of sex on the net requirements for maintenance of Ca (NCam), P (NPm), Mg (NMgm), and K (NKm), estimated using the comparative slaughter technique (CST). This dataset was composed by 154 individual records (53 castrated males, 46 females, and 55 intact males) from three comparative slaughter studies. The second dataset, was constructed to evaluate the effect of sex on NCam, NMgm, and NKm, estimated using the minimum endogenous losses method (MEL). This dataset was assembled with 155 individual records (67 castrated males, 40 females, and 48 intact males) from four feeding trials. The third dataset was constructed to evaluate the effect of sex on the net requirements for growth of Ca (NCag), P (NPg), Mg (NMgg), Na (NNag), and K (NKg) considering or not the degree of maturity of the goat on the estimations. This dataset comprised by 209 individual records (69 castrated males, 69 females, and 71 intact males) from six comparative slaughter studies. Mineral requirements for maintenance using CST were calculated from the intercept of the linear regression between mineral retention and the mineral intake. Using the MEL, mineral requirements for maintenance were calculated from the intercept of a linear regression ... (Complete abstract click electronic access below)
Resumo: O objetivo deste estudo foi avaliar o efeito do sexo nas exigências liquidas de macrominerais para mantença e crescimento para caprinos Saanen de 5 a 45 kg de peso corporal (PC).

The objective of this research was to estimate, using the comparative slaughter technique, energy and protein requirements for maintenance and growth of castrated males, intact males and females Saanen goat kids between 15 and 30 kg of body weight and to evaluate the models from AFRC (1998) and NRC (2007) for predicting dry matter intake (DMI) and average daily gain (ADG) of growing goats. To determine net energy and net protein requirements for maintenance 25 castrate males, 26 intact males and 24 females were used, where 7 castrated males, 8 intact males and 6 females were randomly selected to estimate the initial empty body composition. The remaining animals, 18 castrate males, 18 intact males, and 18 females were used with dietary treatments that consisted of 3 levels of intake: ad libitum, 75% and 50% of ad libitum intake. Within each sex, six blocks of 3 animals each were formed. Within each block, one animal was randomly assigned to each level of intake. Thus, pair feeding was established within each block based on the intake of the animal fed ad libitum. All animals within a block were slaughtered when the animal fed ad libitum reached 30 kg of BW. The 75 and 50% of ad libitum rationing were determined daily based on the DMI of the animal fed ad libitum on the previous day. The net energy and net protein requirements for gain (NEg and NPg, respectively) were obtained using 20 castrated males, 20 intact males and 18 females.

Full textResumo: A taxa de passagem da digesta (kp) em ruminantes é a passagem fracionada da digesta por hora, isto é /h. A kp é um processo complexo e dinâmico e afeta a digestão dos alimentos e o impacto ambiental da produção animal. Neste estudo, objetivamos compreender os fatores relacionados à kp em todo o trato gastrointestinal (TGI) de caprinos em crescimento e caprinos alimentados com níveis de alimentação e propor equações para prever kp de partículas e solutos no reticulo-rúmen. Para isso, utilizamos um banco de dados de dois estudos com caprinos Saanen, que foi dividido em dois bancos de dados diferentes: o banco de dados Crescimento foi composto por registros individuais de machos castrados (n = 36), fêmeas (n = 34) e machos intactos (n = 33) alimentados ad libitum e abatidos aos 15, 22, 30, 37 e 45 kg de peso corporal (PC); e, o banco de dados níveis de alimentação foi composto por registros individuais de machos castrados (n = 38), fêmeas (n = 33) e machos intactos (n = 36) alimentados ad libitum, 75 ou 50% ad libitum durante 109 ± 10 dias . Nossos resultados demonstraram que a taxa de passagem da digesta tem respostas diferentes, quando avaliada em cabras em crescimento ou cabras alimentadas com níveis de alimentação a longo prazo. O kp de partículas no reticulo-rúmen não foi afetado pelo crescimento animal ou pelo nível de alimentação.

Abstract: The digesta passage rate (kp) in ruminants is a fractional passage of digesta per hour, i.e. /h. The kp is a very complex and dynamic process and affects feed digestion and the environmental impact of livestock. In this study, we aimed to understand the factors related to kp in the whole gastrointestinal tract (GIT) of growing goats and goats fed with feeding levels and propose equations for predicting kp of particles and solutes in reticulorumen. For that, we used a database from two studies with Saanen goats that was split into two different databases: database Growth was composed by individual records of castrated males (n = 36), females (n = 34), and intact males (n = 33) fed ad libitum and slaughtered at 15, 22, 30, 37, and 45 kg body weight (BW); and, database Feeding Levels was composed by individual records of castrated males (n = 38), females (n = 33), and intact males (n = 36) fed ad libitum, 75 or 50% of ad libitum over 109 ± 10 days. Our results demonstrated digesta passage rate had different responses whether evaluated in growing goats or goats fed with feeding levels over long-term. Reticulorumen kp of particles was not affected by growth or feeding level. However, reticulorumen kp of particles and large intestines kp of particles and solutes were positively related among them in growing goats. Reticulorumen kp of solutes decreased with aging followed by increasing on reticulorumen capacity and reducing on dry matter (DM) intake level and chewing investment (che...
