| Popis: | portuguesObjetivou-se avaliar se o soro de queijo associado ou nao ao leite de transicao poderia servir como uma alternativa adequada ao leite integral para a criacao de bezerros. Para isso, 24 bezerros machos, mesticos Holandes-Zebu, foram distribuidos em delineamento inteiramente casualizado com tres tratamentos (oito bezerros por tratamento) e alimentados por 60 dias com uma das seguintes dietas liquidas: i) 100% leite integral; ii) 50% de leite integral e 50% de soro de queijo, e iii) 30% de leite de transicao e 70% de soro de queijo. Nao houve diferenca na ingestao de alimentos entre os tratamentos. A analise mostrou que a substituicao do leite integral nao alterou o peso do estomago ou a proliferacao das celulas ruminais quando comparado ao tratamento com 100% de leite integral. No entanto, o grupo de soro de queijo/leite de transicao mostrou papilas ruminais maiores. Esses resultados sugerem que uma dieta de soro de queijo com leite de transicao associada a alimentos solidos e a complementos nutricionais apropriados pode aumentar o desenvolvimento pos-natal de papilas no rumen de bezerros, o que pode contribuir para prepara-los para o desmame EnglishThis study aimed to evaluate whether cheese whey associated with transitional milk or not, could serve as a suitable alternative to whole milk for calf rearing. For this, twenty-four male calves of crossbred Holstein-Zebu, were distributed in a completely randomized design with three treatments (8 calves per treatment) and fed for 60 days with one of the following liquid diets: i) 100% whole milk, ii) 50% whole milk and 50% cheese whey, and iii) 30% transitional milk and 70% cheese whey. There was no difference in food intake between treatments. The analysis showed that whole milk replacement did not alter the stomach weight or the ruminal cell proliferation when compared to treatment using 100% whole milk; however, the transitional milk/cheese whey group showed larger ruminal papillae. These results suggested that a transitional milk-cheese whey diet associated with solid food and proper nutrient complements might enhance the post-natal development of rumen papillae in calves, which might contribute to prepare them for weaning. |
