Resumo: | To evaluate the effect of the fractionated nursing system in rumen development were used 12 Holstein calves, with an initial body weight average of 37.0 kg, individually maintained in holding pens. Conventional treatment was made with four liters of milk daily, during 60 days and fractionated nursing was composed by six liters from the 6th until 25th day, four liters of 26 to 45 and two liters from 46 to 59 days of life. Besides that liquid diet, Cynodon sp. hay, water and mineral supplement were freely offered. Food consumption was monitored daily. The animals were weighted weekly at morning, after the delivery of liquid diet. At 60 days, the calves were euthanized and the digestive system was weighted and rumen papillae were microscopically measured. The nursing system did not interfere significantly in concentrate, hay and total dry matter intake. In contrast, fractionated nursing resulted in higher body weight at 60 days and significant increase in absolute weight of digestive tract, rumen-reticulum, omasum and intestines, so as relative weight of omasum, intestines and mitotic index of ruminal papillae. The fractionated nursing system may be a feeding alternative to improve the rumen development and of calves. |

O tratamento convencional constituiu-se de quatro litros de leite diários durante 60 dias e o fracionado, de seis litros do 6º ao 25º dia; quatro litros dos dias 26 a 45 e dois litros de 46 a 59 dias de vida, além de concentrado, feno de Cynodon sp., água e suplemento mineral, oferecidos livremente. O consumo dos alimentos foi monitorado diariamente e os animais, pesados semanalmente, após o fornecimento da dieta líquida, pela manhã. Aos 60 dias de vida, os animais foram abatidos e realizaram-se pesagens do trato digestivo e medidas histológicas das papilas ruminais. O sistema de aleitamento não interferiu significativamente no consumo de concentrado, de feno, de matéria seca total e no peso corporal final vazio. O aleitamento fracionado resultou em maior peso corporal final, pesos absolutos do trato digestivo, do ruminorretículo, do omaso e dos intestinos, de pesos relativos do omaso e dos intestinos e maior índice mitótico das papilas ruminais. O sistema de aleitamento fracionado pode ser alternativa para melhorar o desenvolvimento ruminal e o desempenho de bezerros.Colégio Brasileiro de Patologia Animal (CBPA)2020-10-04T02:30:05Z2020-10-04T02:30:05Z2013-07info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfAZEVEDO, R.
