日粮精料中麸皮比例对西门塔尔杂交后备母牛日粮营养物质消化率的影响
Effects of Dietary Concentrates with Different Wheat Bran Proportions on the Nutrients'Apparent Digestibilities in Heifers
摘要
Abstract
The objective of this study was to determine the effects of dietary concentrates with different wheat bran proportions on the nutrients' apparent digestibilities in heifers.The proportions of wheat bran in six treatments were 0 ％, 10 ％, 20 ％, 30 ％,40 ％ and 50 ％, respectively. The diets were fed to 24 heifers of Simmental cross (Simmental ×Chinese yellow cattle) for 2 months. All feces were collected using the direct collection during the last week. The results showed that the apparent digestibilites of organic matter, crude protein, starch, NDF had no significant differences among different treatments (P＞0.05).The total tract digestibilities of organic matter,crude protein,starch and NDF were 49.40 ％～55.52 ％ ,48.56 ％～53.90 ％,88.87 ％～93.29 ％ and 48.11％～57.91％,respectively.关键词
