摘要
笼养产蛋鸡出血性脂肪肝综合症多发生于高产鸡群,由于脂肪过度沉积,症状突然爆发.其病因可能是由于遗传、营养、环境和激素等方面,引起肝脏脂肪来源(饲料和肝合成)多于去路(以极低密度脂蛋白输出及在肝脏的氧化),使肝脂代谢平衡失调.本病要以预防为主,合理搭配饲料,适当降低代谢能和提高蛋白质的含量,饲料中应有足够的亲脂因子,防止饲料变质,适当的限制饲养,选择适当体重和防止应激等综合措施,都能控制本病的发生.当饲料中亲脂因子不足情况下发生的出血性脂肪肝综合症,服用氯化胆碱等也可得到治疗的目的.
FLHS often occurs in high-yielding strain of chickens.Its characteristics is liver lipid deposition and sudden break out.The origin of this disease may probably relate to genetic factor, nutritive disturbance, bad ambient condition and unbalance of hormones. The absorption of hepatic lipid may be greater than expense of it. Thus, the metabolic unbalance disturbances of hepatic lipid may be the cause of this disease.
The preventive measures of FLHS may be as follows:
1. To regulate ration, namely, reduce the metabolic energy and increase the content of protein, especially supply sufficient lipophilic factor.
2. To prevent the qualitative change of food.
3. To restrain the quantity of food Properly.
4. To choose the body weight of lay hens.
5. To avoid the stress.
The application of chlorocholine may be effective to FLHS, as the disease is caused by insuficient lipophilic factor in food.
