液体纳米维生素对肉仔鸡生产性能和胴体品质的影响

Effects of Liquid Nano Vitamin on the Growth Performance and Carcass Quality of Broilers

试验选用480只1日龄健康艾维茵肉仔鸡,随机分为4组,每组设4个重复,每个重复30只。对照组饲喂基础日粮,3个试验组分别给予含液体纳米维生素4000、6000、8000倍稀释液的饮水。试验期为42d。试验旨在研究液体纳米维生素对肉仔鸡生产性能和胴体品质的影响。结果表明,液体纳米维生素能显著提高肉仔鸡的平均日增重、饲料利用率和出栏重(P<0.01),可显著降低肉仔鸡均日采食量和死亡率(P<0.01);屠宰试验测定表明,液体纳米维生素可显著提高肉仔鸡半净膛率、全净膛率、胸肌率和腿肌率(P<0.01),对屠宰率也有一定影响,但差异不显著(P>0.05)。因此,液体纳米维生素能显著提高肉仔鸡的生产性能以及改善胴体品质,且较高水平的液体纳米维生素会产生较好的生产效率。

480 one-day-old healthy Avian broilers were selected and randomly divided into four groups, with four repetitions in each group, with 30 broilers in each repetition. In control group, the broilers were fed with the basic diet. In three test groups, the broilers were given with diluent of liquid nano vitamin by 4 000,6 000 and 8 000 times. The experiment lasted 42 days. The experiment was conducted to study the effects of liquid nano vitamin on the growth performance and carcass quality of broilers. The results showed that liquid nano vitamin increased significantly the average daily weight gain,the feed efficiency and slaughter weight of broilers （P〈O.O1） and significantly decreased the average daily intake and death rate of broilers （P〈O.O1）. The slaughter test results showed that hquid nano vitamin could significantly increase the semi-eviscerated percentage,full-eviscerated percentage,breast muscle ratio and leg muscle ratio of broilers （P〈O.OI）, and it had certain effects on the slaughter rate, without significant difference （P 〉0.05 ）. In a word, liquid nano vitamin could significantly improve the growth performance and carcass quality of broilers and higher level of liquid nano vitamin had better production efficiency.
