Nos países de clima tropical como é o caso do Brasil, a pecuária bovina se dá em sua grande maioria sistemas produção baseados na forragem principal fonte alimento. As dimensões continentais e variabilidade climática, tornam as estratégias nutricionais dinâmicas ao longo ano, tendo esta que acompanhar variação da qualidade acordo com metas produtivas pré-determinadas pelo produtor rural. Contudo, uma estratégia nutricional não aporta, necessariamente, mesmo desempenho épocas diferentes sob...
The objective of this study was to evaluate the influence artificial shading on weight gain and meat quality male Nellore cattle in an intensive production system. experiment conducted experimental feedlot Course Animal Science at Universidade Estadual de Goiás, from July October 2014. Forty-eight with average initial 310 kg were kept double 24-m2 stalls, a total 24 stalls. Of these, six open air; covered black shade netting 30% light interception; 50%; 80%, providing 6 m2 per stall. ration...
The influence of artificial shading on environmental variables and behavioral responses Nellore steers in an intensive production system was evaluated this study. experiment conducted the experimental feedlot Department Animal Science at Universidade Estadual de Goiás, from July to October 2014. Forty-eight male cattle with average initial weight 310 kg were kept double 24-m2 stalls, a total 24 stalls. Of these, six open air; covered black shade netting 30% light interception; 50%; 80%,...
The aim of this study was to evaluate thermoregulatory, behavioral, and production traits Holstein/Gir dairy cows different genetic compositions. experiment carried out in the municipality Turvânia - GO, Brazil, from July December 2017. Twenty lactating two groups (½ ¾ [HG]) were used a completely randomized design where they subjected rotational-grazing system 24 irrigated Mombasa grass pastures with one day occupation days rest, fed 22% CP supplemental concentrate diet. During experimental...
O aproveitamento de bezerros leiteiros para produção carne, torna-se um subsídio que a cadeia produtiva propriedades rurais alcance resultados econômicos satisfatórios e sustentabilidade do empreendimento rural. Objetivou-se avaliar o desempenho qualidade carcaça carne origem leiteira confinados. experimento foi desenvolvido na Fazenda Quadalajara, município Turvânia, Goiás. Utilizou-se 16 machos da própria propriedade, em confinamento, onde todos os animais receberam mesma dieta. Foi...
Os parâmetros zootécnicos têm a finalidade supervisionar eficiência do sistema e maior desemprenho, buscando maximização da produção com menores custos, consequentemente, gerando lucros ao produtor. Para poder realizar monitoria dos índices, é imprescindível o monitoramento atividade por meio de anotações acerca toda atividade. O presente trabalho teve como objetivo comparar os índices obtidos na granja suinícola durante primavera/verão outono/inverno, literatura. dados reprodutivos/gestação...
Abstract The complete rearing cycle of dairy calves is not yet widely adopted by rural producers, possibly because they do perceive these animals as potential meat producers or are unaware their production capabilities. This study aimed to assess the economic viability through entire growth cycle. Sixteen Holstein × Gyr crossbred were assessed, originating from farming, with an average initial weight 40.67 ± 5.27 kg and slaughtered at 10 months age, reaching a final 320.4 45.87 kg. These...
ABSTRACT The aim of this study was to evaluate the performance and carcass meat quality sheep in an intensive production system with without artificial shade available. Twenty Santa Inês × Dorper crossbred lambs were allotted two collective stalls, one which covered a black polypropylene net 80% light interception, providing 2.5 m2 animal-1. Performance evaluated by measuring initial weight, final yield, average daily weight gain, total gain. Carcass traits based on variables fatness,...
The objective of this study was to evaluate the influence a synthetic progesterone ear implant on behavior, physiological responses, and number carcass injuries Nellore females. Twenty-eight heifers with an average initial weight 240.89 kg were used in experiment. All animals received same dietary management, intensive rearing system mineral salt water ad libitum. Heifers distributed completely randomized design two treatments (with without implant) seven replications, 14 stalls. Analyses...
Resumo Objetivou-se avaliar o efeito residual de doses Nitrogênio (N) aplicadas em pastos Brachiaria brizantha (cvs. Marandu e Xaraés) por dois anos consecutivos sobre a produção milho para silagem, sistema integração lavoura-pecuária. A adubação nitrogenada dos foi realizada durante consecutivos, utilizando-se quatro dosagens (0, 100, 200 300 kg/ha/ano). Estas áreas foram dessecadas plantio direto do milho. Foi utilizada uma basal 70 kg N/ha cultivo milho, aplicado cobertura. Foram...
The objective of this study was to compare the productive, behavioral and physiological performance feedlot Guzerat ½ × Aberdeen Angus cattle. experiment conducted in a commercial for 80 days, between April June 2016. Fifteen male 15 Guzerat-Aberdeen cattle, both at same age, with respective average initial weights 381.27 401.34 ± 54.70 kg, were used. animals kept collective pens, one each breed group, 14 m2 available per animal. Environmental conditions, respiratory frequency behavior...
The aim of this study was to examine the behavioral, productive, reproductive and thermoregulatory performance 3/4 7/8 Holstein/Gir (HG) dairy cows identify which genetic composition suffers least heat stress. A completely randomized design adopted involving 20 multiparous, lactating crossbred from a farm located in municipality Turvânia - GO, Brazil. During experimental period, data on traits were collected every 15 days. Bioestat (5.0) statistical software used for analysis. mean...
Artificial shading is widely used to provide thermal comfort animals and has been extensively researched due its relationship with their welfare performance. This study examines the physiological behavioral traits of sheep in a feedlot system without access shade. Twenty male Santa Inês × Dorper crossbred an initial average weight 25 kg were experiment. The kept two collective stalls, one which was equipped polypropylene mesh shade net 80% light interception capacity. experiment conducted...
