【摘要】：試驗(yàn)旨在研究飼料中添加不同劑量的卷心菜漿液對(duì)肉雞生長性能、血液生化指標(biāo)和免疫器官指數(shù)的影響。試驗(yàn)選取健康、體重相近的1日齡肉仔雞200只,隨機(jī)分為4組,每組5個(gè)重復(fù),每個(gè)重復(fù)10只雞。對(duì)照組飼喂基礎(chǔ)日糧,試驗(yàn)Ⅰ、Ⅱ組和Ⅲ組分別在基礎(chǔ)日糧中添加10、15、20 g/kg卷心菜漿液,試驗(yàn)期42 d。于試驗(yàn)第21、42天分別稱重、計(jì)算采食量,采集血樣測定血液生化指標(biāo),采集胸腺、脾臟、法氏囊稱重計(jì)算免疫器官指數(shù)。結(jié)果表明:與對(duì)照組相比,試驗(yàn)Ⅲ組22~42 d采食量、日增重顯著提高(P0.05),試驗(yàn)Ⅲ組42 d體重顯著提高(P0.05);與對(duì)照組相比,試驗(yàn)Ⅲ組1~21 d胸腺、脾臟指數(shù)顯著提高(P0.05),試驗(yàn)Ⅲ組22~42 d胸腺指數(shù)顯著提高(P0.05);試驗(yàn)Ⅲ組1~21 d血清堿性磷酸酶活力、高密度脂蛋白含量顯著高于對(duì)照組(P0.05)。本試驗(yàn)條件下,卷心菜漿液可提高肉雞22~42 d日增重,提高肉雞42 d出欄體重,提高肉雞1~21 d胸腺、脾臟指數(shù),以20 g/kg添加劑量效果顯著。
[Abstract]:The purpose of this study was to study the effects of different doses of cabbage serosa on growth performance, blood biochemical index and immune organ index of broilers. A total of 200 1-day-old broilers of similar body weight were randomly divided into 4 groups with 5 replicates in each group and 10 chickens in each group. The control group was fed with basal diet and the trial groups 鈪，
