Abstract

In order to provide information on the state of hydration of broilers during marketing, 7-week-old Ross broilers of mixed sex were kept at 17 or 23 degrees C and deprived of food, or food and water, for 24 h. Measurements were made of live weight, carcass weight, muscle moisture, packed cell volume, plasma glucose, corticosterone, total protein, osmolality and sodium. There was a decrease in live weight, carcass weight, plasma glucose and plasma total protein, and an increase in packed cell volume and corticosterone, in birds deprived of food, or food and water. Muscle moisture increased in birds deprived of food and decreased in birds deprived of food and water. Osmolality decreased in birds deprived of food, the decrease being greater in birds at 23 degrees C. Plasma sodium levels were higher in birds kept at 23 degrees C and increased only in birds deprived of food and water at 23 degrees C.

摘要

为了提供有关肉鸡上市期间水合状态的信息，将7周龄的罗斯混合性别肉鸡饲养在17或23摄氏度环境下，并禁食24小时，或禁食禁水24小时。测量了活体重、胴体重、肌肉水分、红细胞压积、血浆葡萄糖、皮质酮、总蛋白、渗透压和钠含量。禁食或禁食禁水的鸡只，其活体重、胴体重、血浆葡萄糖和血浆总蛋白降低，红细胞压积和皮质酮升高。禁食的鸡只肌肉水分增加，禁食禁水的鸡只肌肉水分减少。禁食的鸡只渗透压降低，23摄氏度环境下的鸡只降低幅度更大。饲养在23摄氏度环境下的鸡只血浆钠水平较高，且仅在23摄氏度环境下禁食禁水的鸡只中升高。
