【摘要】:本試驗(yàn)旨在研究母雞飼糧中添加不同水平肌苷酸(IMP)對(duì)種蛋品質(zhì)、1~21日齡子代肉雞生長(zhǎng)性能和血清生化指標(biāo)的影響。選取20周齡健康愛拔益加(Arbor Acres)肉雞480只,隨機(jī)分為對(duì)照組(基礎(chǔ)飼糧)、Ⅰ組(基礎(chǔ)飼糧+0.2%肌苷酸)、Ⅱ組(基礎(chǔ)飼糧+0.5%肌苷酸)和Ⅲ組(基礎(chǔ)飼糧+1.0%肌苷酸)。出殼后的子代肉雞隨機(jī)選取480只,根據(jù)其母雞飼糧中肌苷酸添加情況相應(yīng)分為對(duì)照組、Ⅰ組、Ⅱ組和Ⅲ組,每組6個(gè)重復(fù),每個(gè)重復(fù)20只雞。試驗(yàn)期21 d。結(jié)果表明:與對(duì)照組相比,各試驗(yàn)組32周齡末母雞的種蛋品質(zhì)指標(biāo)、1~21日齡子代肉雞的生長(zhǎng)性能指標(biāo)和血清蛋白質(zhì)代謝及酶活性相關(guān)指標(biāo)均無顯著差異(P0.05)。與對(duì)照組相比,Ⅲ組21日齡子代肉雞的血清高密度脂蛋白膽固醇(HLD-C)含量顯著升高(P0.05),各試驗(yàn)組的血清總膽固醇(T-CHO)、甘油三酯(TG)和低密度脂蛋白膽固醇(LDL-C)含量無顯著差異(P0.05)。與對(duì)照組相比,Ⅱ組和Ⅲ組21日齡子代肉雞的血清三碘甲狀腺原氨酸(T_3)含量顯著升高(P0.05),Ⅱ組的血清甲狀腺素(T4)和胰島素樣生長(zhǎng)因子-1(IGF-1)含量顯著升高(P0.05),各試驗(yàn)組的血清生長(zhǎng)激素(GH)含量無顯著差異(P0.05)。與對(duì)照組相比,Ⅲ組21日齡子代肉雞的血清免疫球蛋白M(Ig M)、白細(xì)胞介素2(IL-2)和白細(xì)胞介素6(IL-6)含量有上升趨勢(shì)(P0.05)。以上結(jié)果表明,母雞飼糧添加肌苷酸增強(qiáng)了子代肉雞體內(nèi)的脂質(zhì)代謝,提高了子代肉雞血清生長(zhǎng)與免疫相關(guān)激素水平和免疫因子含量;綜合種蛋品質(zhì)、生長(zhǎng)性能及血清生化指標(biāo),母雞飼糧添加0.5%~1.0%肌苷酸效果最佳。
[Abstract]:The purpose of this experiment was to study the effects of different levels of inosinic acid (IMP) on egg quality, growth performance and serum biochemical indexes of broiler broilers at the age of 1 ~ 21 days. Twenty-week-old healthy Alba Yiyi and (Arbor Acres) broilers were randomly divided into control group (basal diet), group 鈪,
