Influence Of Natural Cellulose Concentrates On The Growth Performance Of Nursing Calves

The growth and development status of nursing calves influences directlythe production performance of dairy cows. The function of digestive organs ofnursing calves has not been built completely yet at this stage, it is easy tocause various adverse reactions, affecting the growth and development.Therefore it is particularly important that how to choose high-quality feed fornursing calves. In this study, we want to discuss the influence of a naturalcellulose concentrates on the feed intake, body weight, size, rumendevelopment, diarrhea and gastrointestinal digestive function when nursingcalves were fed it. The results showed that the feed intake in the experimentalgroups was higher than the control groups overall, but the differences was notsignificant； and the crude feed intake in the experimental groups wassignificantly higher than that of the control; the body weight and body size ofthe experimental groups was better, but the differences was not significant; thebody height of the experimental groups was significantly higher than that ofcontrol(p<0.05).In experimental groups, the situation of rumen developmentwas better, with dark color and large volume, and the thickness of rumen wallincreased significantly by an average of26.09%(p <0.05); and the length andthe number of rumen/cm2increased significantly by an average of12.14%and15.3, respectively(p <0.05); in experimental groups, the digestibility of NDF、ADF、CP、EE and Ash was improved, especially that of NDF and ADF wassignificantly higher(p<0.05) and the forming of manure was better by scoring.From this experiment, we made initial conclusion that this celluloseconcentrate can increase the feed intake in nursing calves, especially theintake of rough material, which will help to promote early rumen development,improve digestion and gastrointestinal function, to prevent calf diarrhea.Thus,it is suitable for nursing calves.
