复方维生素纳米乳促进樱桃谷肉鸭生长性能的效果研究

Study on compound vitamin nanoemulsion on promoting the growth performance of Cherry Valley ducks

为了研究复方维生素纳米乳制剂对樱桃谷肉鸭生长性能的影响,并探索其在樱桃谷肉鸭日粮中适宜的添加比例,试验选择23日龄健康樱桃谷肉鸭,测定了不同浓度(0.4,0.2,0.13 m L/kg)复方维生素纳米乳对其平均日采食量、平均日增重和料重比等的影响。结果表明:日粮中添加复方维生素纳米乳后肉鸭生长性能均有显著提高(P<0.05);添加0.4 m L/kg复方维生素纳米乳对肉鸭生长性能的提高效果最好。

To study the effect of compound vitamin nanoemulsion preparation on the growth performance of Cherry Valley meat ducks, and to explore suitable proportions for adding the nanoemulsion preparation of compound vitamin in their diets, 23 - day - old healthy Cherry Valley meat ducks were selected, and the effects of different concentrations of compound vitamin nanoemulsion on the average daily feed intake, average daily weight gain, feed - to - gain ratio, and other indexes of Cherry Valley meat ducks were determined, including 0.4, 0.2, 0.13 mL/kg compound vitamin nanoemulsion. The results showed that the growth performance of the meat ducks could be signifieandy improved after adding compound vitamin nanoemulsion in the diet the, adding 0.4 mL/kg compound vitamin nanoemulsion had a better effect on the improvement of growth performance of Cherry Valley meat ducks.
