摘要
本试验旨在探究夏秋茶绿茶粉对产蛋后期皖南三黄鸡产蛋性能、屠宰性能和血液生化指标的影响。将健康状况良好、体重相近的108只62周龄皖南三黄鸡母鸡随机分为对照组(GTP 0)、GTP 0.5组、GTP 1.0组和GTP 1.5组,每组3个重复,每个重复9只。对照组饲喂玉米-豆粕型基础日粮,GTP 0.5组、GTP 1.0组和GTP 1.5组分别饲喂含0.5%、1.0%和1.5%绿茶粉的基础日粮。试验期8周。结果显示:与对照组相比,试验组产蛋率显著降低(P<0.05);GTP 1.0组平均蛋重显著高于对照组(P<0.05),GTP 0.5组和GTP 1.5组平均蛋重和日采食量均低于对照组,而料蛋比则高于对照组(P<0.05);试验组腹脂率随着GTP添加量增加呈降低趋势,其中GTP 1.5组腹脂率显著低于对照组(P<0.05);GTP 0.5组血液总胆固醇(T-CH)含量显著低于对照组(P<0.05);GTP 0.5组血液丙二醛(MDA)含量显著低于对照组(P<0.05),而超氧化物歧化酶(SOD)和谷胱甘肽过氧化物酶(GSH-Px)含量则显著高于对照组(P<0.05)。综上所述,在本试验条件下,添加绿茶粉可以改善产蛋后期皖南三黄鸡的血液生化指标和降低腹脂率,但同时也降低了产蛋性能。
This experiment was conducted to study the effects of green tea powder from summer and autumn tea on the laying performance,slaughtering performance and blood biochemical indexes of Wannan yellow chicken during late laying period.A total of 10862-week-old Wannan yellow chickens were randomly allocated into control group(GTP 0),GTP 0.5 group,GTP 1.0 group and GTP 1.5 group,with 3 replicates in each group,and 9 hens per replicate.The control group was fed a basic diet of corn-soybean meal,the GTP 0.5 group,GTP 1.0 group and GTP 1.5 group were fed diets containing 0.5%,1.0%and 1.5%green tea powder,respectively.The trial lasted 8 weeks.The results showed as follows:Dietary green tea powder supplementation significantly decreased the egg production rate in the experimental group compared to the control group(P<0.05).The average egg weight in the GTP 1.0 group was higher than that of control group(P<0.05).The average egg weight and average daily feed intake in the GTP0.5 and GTP 1.5 group was lower than that of control group(P<0.05),however,the feed conversion rate was higher than that in control group(P<0.05).The abdominal fat percentage of experimental groups was decreased with the increase of GTP supplemental level,and the abdominal fat percentage of GTP 1.5 group was significantly lower than that of control group(P<0.05).The T-CH content in GTP 0.5 group was significantly lower than that in control group(P<0.05).The blood MDA content in GTP 0.5 group was significantly lower,but the contents of SOD and GSH-Px were significantly higher than that in control group(P<0.05).In summary,during the experiment,dietary green tea powder supplementation improved blood biochemical indexes and helped to reduce percentage of abdominal fat,but also reduced the laying performance.
