摘要/Abstract

摘要： 试验选用健康、体重相近的肉鸡100羽(公母各半)。随机分为4个处理，日粮中添加CLA分别为0%（对照组）、0.25%、0.5%、1%，试验期60 d。结束时每组随机抽取15羽进行屠宰。研究添加不同水平的CLA对肉鸡肌肉脂肪酸组成的影响。结果显示，与对照组相比，豆寇酸含量分别提高16.18%(P>0.05)、30.49%(P<0.01)、40.63%(P<0.01)；棕榈酸含量分别提高9.38%(P>0.05)、23.81%(P<0.05)、24.73%(P<0.05)；棕榈油酸含量分别降低5.00%、5.31%、29.00%(P<0.05)；硬脂酸含量分别提高19.62%、23.41%、33.46%；油酸含量降低14.48%、16.52%、27.23%；亚油酸添加0.25% CLA组提高0.72%，其中添加0.5%和1%组分别下降20.75%(P<0.01)、7.1%；亚麻酸含量分别提高90.00%(P<0.01)、92.81%(P<0.01)、93.33%(P<0.01)。

Abstract: During the experiment, fifty male and fifty female chickens of similar weight were selected. Chickens were randomly divided into four groups. Four concentration of conjuqared linoleic acid (CLA) were applied for each group, which were 0% (CK), 0.25%, 0.5%, 1%. After sixty days experiment, fifteen chickens of each group were selected to determine the effect of CLA on fatty acid accumulation. Results indicated that different responses were observed among the fatty acid when application of different content of CLA. Compared to control group, the concentration of myristic acid were increased by 16.18%(P>0.05), 30.49% (P<0.01) and 40.63% (P<0.01) while palmitic acid were increased by 9.38% (P>0.05),23.81% (P<0.05),24.73% (P<0.05); In contrast, the concentration of palmitoleic acid were decreased by 5.00%,5.31%,29.00%(P<0.05). In addition, the concentration of stearic acid were increased by 19.62%,23.41%,33.46%, respectively. On contrary, the concentration of oleic acid were reduced by 14.48%,16.52%,27.23%. The concentration of linoleic acid was increased by 0.72% at the 0.25% CLA treatment, while it was decreased by 20.75%(P<0.01) and 7.1% at the treatment of 0.5% and 1% application of CLA. Apart from the change of linoleic acid, the concentration of linolenic acid were increased by 90.00%(P<0.01),92.81%(P<0.01),93.33%(P<0.01).
