：
肉鸡腹水综合征是危害世界肉鸡健康生产的营养代谢病,多见于寒冷的冬季和气温较低的春秋季节.它不仅会导致肉鸡屠宰率和屠宰品质的下降,更有甚者会造成肉鸡的死亡,因此,每年给世界肉鸡生产造成严重的经济损失.近年来,有研究发现腹水综合征肉鸡会伴有脂肪代谢紊乱的现象发生,但其机理尚不明确.本研究旨在对低温诱导腹水综合征肉鸡肝脏中甘油三酯(TG)代谢情况进行分析,从而为更好解释腹水综合征肉鸡出现脂肪代谢紊乱的现

肉鸡腹水综合征是危害世界肉鸡健康生产的营养代谢病,多见于寒冷的冬季和气温较低的春秋季节.它不仅会导致肉鸡屠宰率和屠宰品质的下降,更有甚者会造成肉鸡的死亡,因此,每年给世界肉鸡生产造成严重的经济损失.近年来,有研究发现腹水综合征肉鸡会伴有脂肪代谢紊乱的现象发生,但其机理尚不明确.本研究旨在对低温诱导腹水综合征肉鸡肝脏中甘油三酯(TG)代谢情况进行分析,从而为更好解释腹水综合征肉鸡出现脂肪代谢紊乱的现象提供理论依据,同时也为肉鸡腹水综合征的防治提供新的思路.

本试验选取体重相近的11周龄蛋鸡公鸡共28只,随机分成对照组(未进行去势手术,14只)、半阉组(摘除1个睾丸,6只)及全阉组(摘除2个睾丸,8只)三组.试验期为6周.在每周同一时间进行行为学视频拍摄和分析,并测定生长形状指标.结果显示:行为学表现方面,去势对公鸡的攻击、啄物、啄羽等行为学表现等无显著影响(P＞0.05),但公鸡一般行为(饮水、采食、伸脚)发生频次有显著变化.生长性能方面,去势对鸡冠
畜禽的繁殖性能主要受下丘脑-垂体-性腺轴(HPGA)的调控,HPGA的主要生殖激素及受体是影响畜禽繁殖力的重要因素,可以作为影响畜禽产卵数的重要候选基因.光照是影响禽类繁殖的重要环境因素,主要通过光照强度、颜色和周期三个方面来影响禽类活动,光照颜色由波长决定,不同波长的光对视网膜有不同的刺激作用,能够导致行为的改变,最终影响禽类的生长、发育和繁殖.I Rozenboim et al(2004)研究
