【摘要】：試驗(yàn)旨在研究飼料加工方法和日糧中添加乙氧喹抗氧化劑對(duì)海蘭褐蛋雛雞生長(zhǎng)性能及抗氧化指標(biāo)的影響。試驗(yàn)將240只21日齡海蘭褐蛋雞隨機(jī)分為四組,每組6個(gè)重復(fù),每個(gè)重復(fù)10只。1組飼喂基礎(chǔ)日糧顆粒料,2組飼喂基礎(chǔ)日糧粉料,3組在1組基礎(chǔ)上添加抗氧化劑乙氧喹,4組在2組基礎(chǔ)上添加抗氧化劑乙氧喹。預(yù)試期為1周,正試期為4周。結(jié)果表明:1組與2組日增重、日采食量、飼料轉(zhuǎn)化比差異均不顯著(P0.05),3組、4組血清中丙二醛(MDA)含量顯著降低(P0.01),3組相對(duì)于1組飼喂5周MDA降低了31.88%。由此可見,日糧中添加乙氧喹能提高蛋雛雞的抗氧化能力,采用二次制粒工藝,對(duì)改善蛋雛雞生長(zhǎng)性能也有良好的效果。
[Abstract]:The purpose of the experiment was to study the effects of dietary supplementation of ethoxyquine antioxidants on growth performance and antioxidant index of Hailan brown egg chicks. 240 21-day-old Hayland brown laying hens were randomly divided into four groups with 6 replicates in each group. Each group of 10 rats was fed with basal diet pellets and 2 groups fed basal diet powder. Group 3 added antioxidant ethoxyquine on the basis of group 1 and group 4 added antioxidant ethoxyquine on the basis of group 2. The pretest period was 1 week and the positive test period was 4 weeks. The results showed that there was no significant difference in daily gain, daily feed intake and feed conversion ratio between group 1 and group 2. The content of malondialdehyde (MDA) in serum of group 3 was significantly lower than that of group 1 (P 0.01). The MDA of group 3 was 31.88% lower than that of group 1 at 5 weeks. It can be seen that adding ethoxaquine to the diet can improve the antioxidant ability of the egg chicks, and the secondary granulation process can also improve the growth performance of the egg chicks.
