摘要

本试验旨在研究水飞蓟油对蛋鸡产蛋性能、蛋品质及鸡蛋脂肪酸组成的影响。试验选用30周龄体况良好、产蛋率接近的如皋黄鸡270只,随机分成3个组,每个组6个重复,每个重复15只鸡。常规饲粮组饲喂玉米-豆粕型饲粮,3%大豆油组饲喂含3%大豆油饲粮,水飞蓟油组饲喂含3%水飞蓟油饲粮。预试期2周,正试期8周。结果表明:1)水飞蓟油组产蛋率、日只蛋重、平均蛋重、日只采食量、料蛋比、破蛋率和死淘率与常规饲粮组和3%大豆油组相比,差异均不显著(P>0.05)。2)水飞蓟油组的蛋黄颜色显著低于常规饲粮组(P<0.05),与3%大豆油组差异不显著(P>0.05),其他蛋品质与常规饲粮组和3%大豆油组相比差异均不显著(P>0.05)。3)水飞蓟油组鸡蛋的饱和脂肪酸总含量显著高于、多不饱和脂肪酸总含量显著低于3%大豆油组(P<0.05),但与常规饲粮组差异不显著(P>0.05)。水飞蓟油组显著增加了鸡蛋α亚麻酸和二十二碳六烯酸(DHA)含量(P<0.05)。由此可见,除蛋黄颜色外,水飞蓟油对蛋鸡产蛋性能和蛋品质无不良影响;相对于大豆油饲粮,水飞蓟油能显著增加蛋鸡鸡蛋饱和脂肪酸总含量,显著降低多不饱和脂肪酸总含量,但与常规饲粮差异不显著;相对于常规饲粮和大豆油饲粮,水飞蓟油能显著增加鸡蛋α亚麻酸和DHA含量。

Abstract

This experiment was conducted to study the effects of Silybum marianum seed oil on laying performance, egg quality and egg fatty acid composition in laying hens. Two hundred and seventy 30-week-old Rugao yellow laying hens with a similar laying rate were assigned to 3 groups with 6 replicates per group and 15 hens per replicate. The diet of control group Ⅰ(conventional diet group) was based on corn and soybean. The diet of control group Ⅱ(3% soybean oil group) contained 3% soybean oil. The diets of experimental group(Silybum marianum seed oil group) contained 3% Silybum marianum seed oil. The pre-test period lasted for 2 weeks and the trail period lasted for 8 weeks. The results showed as follow:1) there were no significant differences in laying rate, daily egg mass, daily feed intake, average egg weight, feed/egg, broken egg rate and mortality among the 3 groups(P>0.05). 2) The yolk color level in the groups which contained 3% soybean oil and Silybum marianum seed oil was less deeper compared with that in the conventional diet group(P<0.05). There was no significant difference in laying performance among the 3 groups(P>0.05) 3) The contents of total saturated fatty acids and polyunsaturated fatty acids in the Silybum marianum seed oil group were much more and less than those in the 3% soybean oil group(P<0.05), respectively,while there were no significant difference between the Silybum marianum seed oil group and the conventional diet group(P>0.05). The contents of α-linolenic oil and docosahexaenoic acid(DHA) in the Silybum marianum seed oil group were much more than those in the conventional diet group and the 3% soybean oil group(P<0.05). It is indicated that the Silybum marianum seed oil has no harmful effects on laying performance and egg quality except the yolk color, and significantly increase the content of α-linolenic oil and DHA in egg compared with conventional diet and soybean oil diet. Also, compared with soybean oil diet, Silybum marianum seed oil diet can significantly increase content of total saturated fatty acids and decrease content of total polyunsaturated fatty acids, but no difference with conventional diet.
