Abstract

The expansion of the biodiesel industry has created opportunities for crude glycerol use in beef cattle diets. The objective of this study was to determine the effects of substituting sorghum grain with crude glycerol on dry matter intake (DMI), weight gain and feed intake pattern of 28 non-castrated Nelore males with initial body weight (BW) of 441 ± 40.2 kg and 21.5 ± 0.5 months of age housed in individual or collective pens. The experiment lasted 98 days (June 29 through October 5, 2015), with a 14 day-period of adaptation and 84 days for data collection. Crude glycerol was included at 15% of the ration dry matter as a replacement for sorghum grain. Orts were collected and weighed daily, and DMI was calculated by difference between feed offered and feed refused. Feed intake pattern was determined every two weeks after the beginning of the study in three intervals relative to feed delivery (0-4, 4-10, and 10-24 hours post-feeding). Animals' BW was obtained on days 1, 13, 27, 41, 55, 69, and 83 days of the trial after a 12-hour solid fasting. Crude glycerol did not alter (P>0.05) DMI, weight gain, hot carcass weight and dressing percentage compared with the control diet. A treatment × days of experiment response (P<0.05) occurred due to a decreased DMI in animals fed crude glycerol during the first 14 days of the trial. Crude glycerol-fed animals decreased (P<0.05) the neutral detergent fiber (NDF) intake pattern in individual and collective pens. Crude glycerol can be recommended at 15% of the total DM ration as a sorghum grain replacement in diets fed to Nelore animals finished in feedlot. [ABSTRACT FROM AUTHOR]

Abstract

forages play a key role on the performance of beef cattle in feedlot systems. Twenty-four non-castrated F1 Red Norte × Nelore males with an average initial body weight (BW) of 439.8 ± 59.6 kg and 21.7± 2.7 months of age were distributed in three experimental groups, and housed either in individual or collective pens (twelve animals in individual pens and twelve in three collective pens) at the Dairy and Beef Research and Education Center of the School-Farm of IF Goiano (Iporá Campus). The experiment lasted 84 days (14 days for adaptation and 70 days for data collection). Animals were fed once daily with diets containing sugar cane in natura (Ci), sugar cane silage (SC) or corn silage (CS) as sources of forage in amounts that ensured 10 to 15% of orts. Feed refusals were measured daily and dry matter intake (DMI) was determined by difference, BW was recorded every two weeks after a twelve-hour fasting period. There was no effect (P>0.05) of source of forage on DMI in animals housed in individual pens, as well as there was no response (P>0.05) of source of forage on growth performance. There was a tendency (P = 0.09) of BW increase in animals housed in individual pens (561.4 ± 21.2 kg) compared with collective pen-housing (509 ± 21.2 kg). Sources of forage did not alter (P>0.05) carcass traits. Animals housed in individual pens increased (P<0.05) empty gastrointestinal tract weight (11.9 kg) compared with animals housed in collective pens (10.2 kg). There was a tendency (0.05≤P≤0.10) of increase in pre-slaughter BW, full gastrointestinal tract weight and liver weight in animals housed in individual pens in comparison with collective pens. Ci, SC and CS can be recommended for beef cattle feeding in feedlot systems. [ABSTRACT FROM AUTHOR]

Abstract

As forragens desempenham um papel essencial no desempenho de bovinos de corte em confinamento. Vinte e quatro machos não castrados F1 Red Norte × Nelore com peso vivo médio (PV) inicial de 439,8 ± 59,6 kg e 21,7 ± 2,7 meses de idade foram distribuídos em três grupos experimentas e alojados em baias individuais (doze animais) ou coletivas (doze animais em três baias) no Setor de Bovinocultura da Fazenda-Escola do IF Goiano (Câmpus Iporá). O experimento teve duração de 84 dias (14 dias para adaptação e 70 dias para coleta de dados). Alimentaram-se os animais uma vez ao dia com dietas à base de cana-de-açúcar in natura (Ci), silagem de cana (SC) ou silagem de milho (SM) como fontes de forragem, procurando-se obter 10 a 15% de sobras. Avaliou-se o consumo de matéria seca (CMS) diariamente pela diferença entre a quantidade oferecida menos a recusada, e registrou-se o PV dos animais a cada 14 dias após jejum de sólidos de doze horas. Não houve efeito (P>0,05) da fonte de forragem sobre o CMS nos animais alojados nas baias individuais, assim como não houve resposta (P>0,05) da fonte de forragem sobre o PV. Houve tendência (P = 0,09) de aumento do PV nos animais alojados em baias individuais (561,4 ± 21,2 kg) em relação às baias coletivas (509 ± 21,2 kg). As fontes de forragem não alteraram (P>0,05) as características da carcaça. Os animais alojados nas baias individuais aumentaram (P

Abstract

With the aim to determine the occurrence of antibodies against Toxoplasma gondii in beef cattle of the region of Guarapuava, Paraná State, Brazil and to correlate this with the age, the sex and the breed of the animals, samples of blood of 250 bovine were obtained and sent to the Zoonoses and Public Health Laboratory of the Preventive Veterinary Medicine Department of the State University of Londrina. After getting the serums, these were stored to -20°C, up to the realization of the examinations. The detection of antibodies anti-T. gondii was carried out by IFAT (cut off ≥1:64). The statistical analysis was carried out through Fisher's exact and of qui-square tests (p≤0,05) to correlate the results of the serology with the analyzed variables. Of 250 evaluated samples of serum, 77 (30.8 %) were positive for T. gondii. The titles obtained were 1:64 (70) and 1:256 (seven). The results demonstrate large distribution of the protozoa among beef cattle in the region of Guarapuava, PR. Animals seropositives were present in 56% (14/25) evaluated properties. Animals mix breed presented higher rates of seropositives for T. gondii (P=0.001). The age presented positive correlation with the occurrence of antibodies against T. gondii (P=0.01), indicating horizontal transmission of the agent. The high incidence of beef cattle positives to T. gondii observed in this work indicates the potential risk of the consumption of meat cattle for the human toxoplasmic infection.

Abstract

O objetivo deste trabalho foi verificar, por meio de simulação, o resultado de vinte anos de seleção para crescimento e habilidade materna na produtividade de um rebanho Nelore puro de origem (PO), marca BRGN (Nelore BRGN), criado no bioma Cerrado. O modelo de simulação utilizado foi o DECI (Decision Evaluator for the Industry Cattle), ao qual foram informados os dados de forma a refletir, o mais fielmente possível, o sistema de produção do rebanho Nelore da Embrapa Cerrados. O modelo de simulação DECI foi eficaz em predizer a resposta à seleção genética para habilidade materna que obteve como resposta direta o aumento de 5,5% na produção de leite, proporcionando maior ganho de peso pré-desmama (9,3%) e aumento no peso do bezerro a desmama (10%). No entanto, foram verificadas maiores médias para peso à maturidade (465 kg), peso da vaca ao parto (476 kg), e peso da vaca na desmama (520 kg), indicando maiores custos de manutenção do rebanho devido ao aumento no tamanho corporal e nas exigências de mantença desses animais. A maior produção de leite das mães acarretou diminuição na condição corporal ao parto (9,3%) e à desmama (3,9%). Sob as condições estudadas, a adoção das técnicas de manejo resultantes da simulação poderá aumentar as taxas produtivas do rebanho Nelore da Embrapa Cerrados.

Abstract

O presente estudo objetivou analisar os níveis plasmáticos de cálcio (Ca), fósforo inorgânico (Pi), cobre (Cu) e zinco (Zn) em vacas de corte primíparas e multíparas, mantidas em campo nativo e suplementadas com misturas minerais comerciais completas, em rebanhos na região Centro-Oeste do Rio Grande do Sul. Amostras sangüíneas foram colhidas nos períodos de Final de Gestação (FG), Pico da Lactação (PL) e Entoure (E). As médias plasmáticas dos elementos minerais analisados estiveram conforme as referências, com exceção do Pi, nas vacas primíparas, no período de E. Entre períodos, nas vacas primíparas, houve diferença significativa nos níveis de Ca, sendo maiores no PL do que no FG; quanto ao Cu, os níveis foram significativamente maiores no E em relação ao FG; no Zn os níveis foram significativamente menores no PL. Nas multíparas, os níveis de Zn foram significativamente menores no período de PL em relação FG. Entre categorias, os níveis de Ca foram significativamente maiores nas primíparas, no PL; quanto ao Cu, os níveis foram significativamente maiores nas primíparas, no período de PL e E. Nas condições em que o estudo foi conduzido, conclui-se que a suplementação mineral completa provém níveis plasmáticos marginais de cálcio, fósforo inorgânico e cobre em ambas as categorias e em todos os períodos produtivos. Mesmo com suplementação mineral irrestrita, o período produtivo exerce influência sobre os níveis plasmáticos de cálcio, cobre e zinco, nas vacas primíparas. Mineral status of supplemented beef herds in Mid-West Rio Grande do Sul State Abstract The objective of the present study was to analyze plasma levels of calcium (Ca), inorganic phosphorus (Pi), magnesium (Mg), copper (Cu), and zinc (Zn) in heifers and mature cows maintained in native pastures with free access to a complete mineral mixture. Blood samples were collected at the end of gestation (FG), at peak of lactation (PL) and during breeding season (E). The mean values for all minerals were around the lower limit of international reference ranges, with exception of Pi in first calf heifers during breeding. Among periods in heifers, Ca was higher during PL than in FG. Copper levels were higher in E than in FG while zinc values were lowest in PL than in the other two periods. Between categories, Ca levels were higher in PL heifers, and Cu was higher during PL and E than in FG. The present results suggest that supplementation with a complete mineral mix sustained only marginal plasma levels of Ca, Pi, and Cu in both groups in all periods studied. Even with free access to mineral supplement, the period of the productive cycle has an influence on plasma levels of Ca, Cu and Zn in first calf heifers.

Abstract

O anestro puerperal em novilhas de 1º cria, é um dos principais fatores para diminuição dos índices de fertilidade no rebanho bovino de corte do Brasil. Atualmente são apresentadas diversas metodologias que buscam a reversão desse anestro, algumas relacionadas às ações de manejo. O presente trabalho objetivou testar um protocolo empregando, manejo de mamada interrompida e suplementação com mistura múltipla, comparando-se ao sistema tradicional da vaca com o bezerro-ao-pé. Os animais foram divididos em dois grupos. O Grupo 1 (N=160 - tratado), formado por animais que foram trabalhados com alteração de manejo ou seja mamada interrompida (aparte de 48 horas dos bezerros, quinzenalmente) e suplementados com um sal energético, disponibilizado para consumo de 300 g/dia, e o Grupo 2 de animais (testemunha - N= 160), sem o regime de mamada interrompida e sem o sal mineral energético. Os animais iniciaram o período de monta de 41 a 90 dias pós-parto, permanecendo com touros por período de 60 dias. Sessenta dias após a retirada dos touros foi feito o diagnóstico de gestação por palpação retal, atingido-se o seguinte resultado: O Grupo 1 de animais (tratado), demostrou eficiencia ao reverter o anestro, resultando em 60,6% de prenhez, ao passo que o grupo testemunha atingiu somente 36,9% dentro do mesmo período de serviço. Estrus induction in beef cattle Abstract The absence of puerperal heat postpartum anestrus in first offspring heifers is one of the major factors for the reduction of fertility in the Brazilian beef cattle herd. Nowadays, there are various methods to revert the anestrus, some related to management. Our aim was to test one protocol with calf milk restriction and energetic diet supplementation, comparing to a traditional method in reverting post partum anestrus. Animals were randomized in 2 groups. In group 1 (treatment) calves had milk restriction (48 hours, every 15 days) (N=160) and had been supplemented with white salt, minerals, soy and corn, calibrated to a daily consumption of 300g/day, and it had been compared to the group B (control group) (N=160). Animals were exposed to mating 41 to 90 days after parturition, staying with bulls for a 60 days period. After 60 days the females had been separated from bulls and gestation diagnostic performed by rectal palpation. The following results were obtained: Group 1 60,6% pregnancy, showing efficacy in reverting anestrus in first off spring heifers. Control group had only 36,9% pregnancy.

Abstract

O objetivo desta pesquisa foi avaliar três grupos genéticos de bovinos (Nelore puro, ½ Nelore + ½ Charolês e Charolês puro) sobre o ganho de peso diário. Foram utilizados 45 animais, sendo: 15 da raça Nelore (NE), 15 ½ Nelore + ½ Charolês (NC) e 15 Charolês puro (CH), com idade média de 20 meses e peso vivo médio de 350 kg. Os animais foram distribuídos aleatoriamente em três piquetes, contendo área total de um hectare cada, com capim Brachiaria brizantha cv. Marandu (Proteína bruta: 6,4%; Matéria Mineral: 9,6%; Fibra em detergente neutro: 64,5%; Fibra em detergente ácido: 34,3%, ambos na matéria seca) numa lotação de 15 animais/ha, totalizando cinco animais de cada grupo genético em cada piquete. Os animais foram pesados individualmente antes de entrarem nos piquetes e logo após o término do experimento. O ganho de peso diário foi calculado através da diferença entre o peso inicial e o peso final divido por 60 dias. O delineamento experimental adotado foi o inteiramente casualisado, com três repetições. Os dados experimentais foram analisados utilizando-se o programa SAEG (Sistema para Análises estatísticas e Genéticas 8.1, 2001), submetidas à análise de variância, considerando como fonte de variação os grupos genéticos, adotando-se um nível de significância de 5% de probabilidade. A comparação entre os efeitos dos grupos genéticos sobre o ganho de peso diário foi realizada por meio do teste de Tukey. Os tratamentos diferiram entre si estatisticamente (P<0,05). Animais da raça Nelore puro (NE) apresentou (GPD) de 0,74 kg, significativamente inferior aos animais do grupo NC e CH com GPD de 0,97 e 1,24 kg, respectivamente. Resultado semelhante foi encontrado por Menezes e Restle (2005), que trabalhando com bovinos de diferentes composições genéticas, zebuíno (Nelore) e taurino (Charolês), observaram maiores ganhos de peso para os animais taurinos, em relação aos zebuínos. Segundo estes autores, o menor ganho de peso apresentado por animais zebuínos pode estar relacionado a menor capacidade de ingestão de alimentos. De acordo com Kippert et al. (2008), o desempenho de bovinos oriundos de cruzamentos se deve aos efeitos da heterose individual e materna, fatos estes que provavelmente explicam o melhor desempenho dos animais Charolês puro e ½ Nelore + ½ Charolês, quando comparados aos Nelores puros neste estudo. Pode se concluir que animais Charolês, puro e mestiço, podem ser recomendados para terminação a pasto, com capim Brachiaria brizantha cv. Marandu, pois, apresentaram desempenho positivo.
