笼养对苏邮1号蛋鸭生产性能与蛋品质的影响
Effects of Cage Rearing System on Production Performance, Egg Quality and Egg Component of Suyou No.1 Laying Ducks
摘要
Abstract
This experiment was conducted to evaluate the effects of different rearing systems on production performance,egg quality and egg component of Suyou No.1 laying ducks.A total of nine hundred Suyou No.1 laying ducks of 70-day-old were randomly divided into 2 groups with 3 replicates per group,the pond-rearing litter system (PRLS) and cage rearing system (CRS).Compared to PRLS laying ducks,the day of 50％ laying rate was two days earlier for CRS duck(P＜0.05),average daily feed intake and the ratio of feed to egg were all decreased significantly to 160.4 g and 2.74 (P＜0.05),respectively.Meanwhile,the crack egg rate in CRS dropped to 2％,which was significantly less than PRLS (P＜0.05);the shape index,shell thickness and yolk color were all significantly lower than that of PRLS (P＜0.01),while there were no significant differences in other egg quality indexes and egg component between two groups.These results indicate that CRS improves the production performance of Suyou No.1 laying ducks,but the yolk color is inferior.关键词
