Abstract - tiature does entering their third lactation were selected from the flock at the Fazenda Pendência near Soledade, Paraíba. They were used in ao experiment to study ration formulations ut!lizing two energy sources which were coro vs ground algaroba pods (Prosopis juliflora) and three protein sources consisting of cottonseed ineal or 1 or 2 percent urea for a total of six ration forinuiations. The ariimals were used in a reversal type study ia which each animal received each ration. Only the last two weeks of the test period were used lo the analyses. The rations containing corn resuited in significantly higher levei of lactation than those containing algaroba pods. Corn has a higher energy level and the performance on the two rations was approximately in ratio to their energy content. The performance on the 1% urea ration did not differ significantly from the ration-utilizing only cottonseed meal as a protein source. The two percent urea rations proved to be less satisfactory than those receiving CSM or 1% urea. Urea tended to give a better response with the corn based ration than the algaroba based ration.
RESPOSTA DAS CABRAS LEITERAS EM LACTAÇAO NATIVAS E EXÓTICAS A RAÇOES COMPLETAS ENVOLVENDO VÂRIOS NÍVEIS DE URSIA E DUAS FONTES DE ENERGIA (VAGENS DE ALGAROBA VS MILHO).
Resumo - Cabras adultas entrando na terceira lactacao foram selecionadas dentro dos rebanhos da Fazenda Pendencia, no municipio de Soledade, PB. Elas foram usadas em um experimento sobre formulacao de racoes utilizando-se duas fontes de energia(milho vs vagens de algaroba) e tres fontes de proteina(torta de algodao, sozinha ou com a adicao de ureia a 1% e 2% na torta de algodao) para um total de seis formulacoes de racao. Os animais receberam todas as racoes em um sistema rotacional por periodo porem apenas as duas ultimas semanas do periodo experimental foram usadas nas analises. As racoes contendo milho contribuiram para niveis de lactacao significativamente maiores do que aquelas contendo vagens de algaroba. Racoes contendo milho apresentaram niveis de energia mais elevados e a performance de cada racao foi na razao direta do nivel de energia. Performance na racao com 1% de ureia nao diferiu significativamente da racao contendo somente torta de algodao como fonte de proteina. As racoes com 2% de ureia provaram ser menos satisfatorias do que aquelas recebendo torta de algodao ou 1% de ureia. A ureia tendeu a apresentar uma melhor resposta com as racoes de milho do que as racoes de algaroba.
