长途运输造成的应激对雏鸡育雏期生产性能的影响

Long Distance Conveyance has an Influence on the Produces Function of Fostering the Chick

【目的】本文比较了因长途运输而导致的应激雏鸡与正常雏鸡的各项生产指标,得出了早期应激影响的范围。【方法】试验采用纯系肉种鸡公母各两部分,分为五个试验处理,每个处理六个重复,其中公鸡为两个处理水平,即应激组和对照组,母鸡为三个处理水平,为严重应激组,轻微应激组和对照组。其中以运输的时间长短来认定应激程度。实验分析测定了各处理组在育雏期前五周的增重情况和死亡率。【结果】:早期的应激对雏鸡育雏期的增重无显著的不良影响,但对雏鸡育雏期的死亡率影响较明显,而且影响随应激时间的延长而进一步加强,但该影响会随饲养时间的延长而不断减弱。

In order to settle the problems so as to guide the produce practice,this text compares the normal new born chick with the new born chick and their all kinds of living standard,we conclude the scope of response influnce. The experiment uses pure meat cocks and chickens,and it is divided into five trial processings,and each trial process repeats six time. Among them rooster,for two prcessing levels,in- clude response groups and eomparation groups. For the hen,include theree processing levels,sever response group, slight group and compa- ration group, we decide the degree of response by the very day of the experiment,we analyze the weight and death rate of each group,the re- sult： the respose of the early period has no evident influnce on the weight of the new born chick,but has evident influnce on the death rate of the chick. The influnce become stronger with the respose shrength become stronger,but become weaker with the time going.
