Effects of Perilla Frutescens Seed Extracts on Performance, Reproductive Hormone and Reproductive Performance of Egg Genus Chicken during the Late Laying Peak Period
摘要
Abstract
In order to investigate the effects of diets added different levels of Perilla frutescens seed extracts on performance,reproductive hormone and reproductive performance of egg genus chicken during the late laying peak period,a total of one thousand and eighty 49-week-old Roman Powder egg genus chicken with the similar body weight and laying rate were randomly divided into 4 groups with 5 replicates per group and 54 hens per replicate in a singlefactor completely randomized experimental design.Control group was fed a basal diet,the experimental groups were fed the basal diet added with 100,200 and 300 mg/kg Perilla frutescens seed extracts,espectively.The experiment lasted for 40 days.The results showed as follows Compared with the control group,the diet added 300 mg/kg Perilla frutescens seed extracts significantly improved laying rate and average daily egg production of egg genus chicken (P＜0.01).The diets added 100,200 and 300 mg/kg Perilla frutescens seed extracts significantly increased the contents of progesterone (day 20) and estradiol (days 20 and 40)in serum of egg genus chickens (P＜0.01),and the diet added 300 mg/kg Perilla frutescens seed extracts significantly decreased testosterone content in serum of egg genus chickens (P＜0.01).The diets added 300mg/kg Perilla frutescens seed extracts significantly increased qualification rate,hatching egg fertilization rate and hatchability and reduced eliminating ratio of egg genus chickens (P＜0.05).These results indicate that the effect of diet adding with 300mg/kg Perilla frutescens seed extracts was the best.It can significantly increase production performance and reproductive performance of egg genus chickens during the late laying peak period.关键词
