饲粮亚油酸水平对产蛋初期蛋鸭产蛋性能、蛋品质及脂类代谢的影响
Effects of Dietary Linoleic Acid Level on Laying Performance, Egg Quality and Lipids Metabolism of Ducks during the Early Laying Period
摘要
Abstract
This experiment was conducted to study the effects of dietary linoleic acid level on laying perform-ance, egg quality and lipids metabolism of ducks during the early laying period. A total of 900 healthy Fujian Longyan ducks with similar body weight were randomly allotted into 6 groups with 6 replicates per group and 25 ducks per replicate. Ducks were fed experimental diets with six supplemental levels of linoleic acid (0.55%, 0.75%, 0.95%, 1.15%, 1.35% and 1.55%) by completely randomized design. The experiment lasted for 4 weeks. The results showed that dietary linoleic acid level did not affect the laying performance of ducks during the early laying period ( P>0.05) , however, when dietary linoleic acid level was 0.95%, we got the best lay-ing rate,egg weight, daily egg mass and the ratio of feed to egg. The yolk color was increased with the increas-ing of dietary linoleic acid level ( P<0.05) . When dietary linoleic acid level was 1.55%, the yolk weight was significantly higher than dietary linoleic acid level was 0.75% ( P<0.05) . Dietary linoleic acid level did not af-fect the plasma biochemistry indicators and the content of triglyceride and cholesterol of liver(P>0.05). The polyunsaturated fatty acids of yolk and liver was increased with the increasing of dietary linoleic acid level ( P<0.05), while the monounsaturated fatty acids of yolk was decreased (P<0.05). The results indicate that we can get better laying performance when dietary linoleic acid level is 0.95%. Dietary linoleic acid level affects the fatty acid profiles in yolk and liver of the ducks.关键词
