【摘要】：為了解橡膠籽餅對(duì)蛋雞生產(chǎn)性能及蛋品質(zhì)的影響,選取25周齡健康海蘭褐蛋雞72只,隨機(jī)分為6個(gè)組,每個(gè)組設(shè)4個(gè)重復(fù),每個(gè)重復(fù)3只雞,對(duì)照組飼喂玉米-豆粕型基礎(chǔ)飼糧,試驗(yàn)Ⅰ~Ⅴ組飼糧分別配合5%、10%、15%、20%和25%的橡膠籽餅,各組飼糧營(yíng)養(yǎng)水平一致,試驗(yàn)期16周。結(jié)果顯示:與對(duì)照組相比,試驗(yàn)Ⅰ組和Ⅱ組日采食量顯著增高(P0.05),其他3個(gè)組差異不顯著(P0.05);除試驗(yàn)Ⅰ組外,其余試驗(yàn)組料蛋比顯著增高(P0.05);除試驗(yàn)Ⅰ組和Ⅱ組外,其余試驗(yàn)組平均蛋重均顯著降低(P0.05);除試驗(yàn)Ⅰ和Ⅴ組外,其余試驗(yàn)組蛋殼厚度顯著增加(P0.05);所有試驗(yàn)組蛋雞體重、產(chǎn)蛋率、蛋黃重、蛋黃比、蛋形指數(shù)、蛋殼比和蛋殼重?zé)o顯著差異(P0.05)。研究結(jié)果表明,飼糧中配合5%~10%橡膠仔餅不影響蛋雞體重、產(chǎn)蛋率,但隨配合比例的提高,蛋雞采食量和蛋殼厚度增加,料蛋比呈現(xiàn)上升趨勢(shì),平均蛋重和腹脂率呈現(xiàn)下降趨勢(shì),雞蛋品質(zhì)不受影響。
[Abstract]:In order to understand the effect of rubber seed cake on the performance and egg quality of laying hens, 72 healthy Hailan brown laying hens aged 25 weeks were randomly divided into 6 groups with 4 replicates in each group and 3 chickens per replica. The control group was fed with corn-soybean meal diet. The diet of group 鈪，
