亚麻籽对蛋鸡产蛋性能及蛋品质的影响
Effects of flaxseed on laying performance and egg quality of laying hens
摘要
Abstract
This study aimed to investigate the effects of flaxseed on laying performance and egg quality in laying hens.A total of 300 healthy 330-day-old Lohmann Pink-shell laying hens with similar body weights under identical rearing conditions were randomly divided into two groups,with five replicates per group and 30 chickens per replicate.The control group feed a basal diet,while the flaxseed group feed a diet supplemented with flaxseed.The pre-test lasted for seven days and the formal test lasted for 28 days.The results showed that the average egg weight in the flaxseed group was extremely lower than that of the control group(P<0.01).The energy content of eggs in flaxseed group was extremely higher than that in control group(P<0.01),the contents of fat and total dietary fiber were significantly higher than that in control group(P<0.05),and the water content was extremely lower than that in control group(P<0.01).The contents of manganese and selenium in eggs of control group were significantly higher than those of flaxseed group(P<0.05),and the contents of copper,zinc and calcium in eggs of control group were significantly lower than those of flaxseed group(P<0.05).The control group eggs contained higher levels of vitamin E,zeaxanthin,β-cryptoxanthin,niacin,and pantothenic acid,while the flaxseed group eggs had higher vitamin A,vitamin D,biotin,and folate.Both groups contained 18 amino acids,with the flaxseed group eggs showing significantly higher aspartic acid,serine,glutamic acid,and essential amino acid levels(P<0.05).Based on essential amino acid scores,chemical scores,and essential amino acid indices,flaxseed-supplemented eggs demonstrated better amino acid balance and higher protein nutritional value.The polyunsaturated fatty acid content in flaxseed-supplemented eggs was significantly higher,with α-linolenic acid levels 8.26 times and ω-3/ω-6 ratios 3.70 times those of the control group,alongside a more balanced ratio of saturated,monounsaturated,and polyunsaturated fatty acids.The study concludes that flaxseed enhances egg umami and overall nutritional quality.关键词
