日粮添加韭菜对种蛋孵化的影响（英文）

Effects of Dietary Supplementation with Chinese Chives for Hyline Brown Breeder Roosters on Breeding Eggs Hatching of Hyline Brown Layers

旨在研究饲料中添加不同比例的韭菜对种蛋孵化的影响。在相同饲养条件下,选取4周龄的海兰褐种公鸡400只,随机分为4组,每组5个重复,每个重复20只。Ⅰ组是对照组,喂基础饲料;Ⅱ组、Ⅲ组、Ⅳ组分别在基础饲料中添加1%、3%、5%的韭菜,饲喂16周,第20周龄结束后,进行人工授精。授精后第4d,每组随机抽取500枚种蛋进行孵化。其中A组为对照组Ⅰ的种蛋,B、C、D组分别是试验组Ⅱ、Ⅲ、Ⅳ组的种蛋。结果显示:饲料中添加适量韭菜可以显著提高种蛋的孵化率、健雏率和平均初生重(P<0.05)。本研究说明了饲料中添加韭菜可提高种蛋的孵化率、健雏率和平均初生重,且添加5%韭菜孵化效果最理想。

The aim of this study was to investigate the effects of dietary supplementation with chinese chives for Hyline Brown breeder roosters on the hatching of breeding eggs in Hyline Brown Layers.Four hundred of 4-weeks-old Hyline Brown breeder roosters were randomly assigned to four groups equally(n = 20).Each treatment was replicated five times.Control group Ⅰwas fed with basal diet and treatment groups were fed with the basal diet supplemented with 1%,3% and 5% chinese chives(test Ⅱ,Ⅲ,Ⅳ) to Hyline Brown breeder roosters.The artificial insemination was done after 16 weeks.The A,B,C and D groups in 24-weeks-old Hyline Brown laying breeders were artificially inseminated by Ⅰ,Ⅱ,Ⅲ and Ⅳ groups of semen of Hyline Brown breeder roosters,one rooster to 20 laying breeders,respectively.Five hundred breeding eggs were randomly selected to incubate after the 4 th day of insemination.The results showed that fertility,hatchability,thrifty chick rate and average birth weight were significantly increased by chinese chives supplementation at level 1%,3% and 5%(P < 0.05).In addition,the usage of 5% chives suggested that it would be preferably added to Hyline Brown breeder roosters' diets.It could be concluded from this study that chinese chives can be a promising dietary supplement to increase breeding eggs hatching in the poultry industry.
