摘要:

目的 本试验旨在探究不同水平脂肪粉对海兰褐蛋鸡产蛋性能、蛋品质、血清生化指标和养分表观代谢率的影响,为脂肪粉在蛋鸡饲粮中的应用提供科学依据。 方法 试验选取270只44周龄海兰褐蛋鸡,随机分为3组,每组6个重复,每个重复15只鸡。对照组提供基础饲粮,试验组在基础饲粮中分别添加2%和4%脂肪粉。预饲期1周,试验期为8周。以重复为单位每日记录产蛋数、异常蛋数、蛋重,每周记录耗料量,统计平均日采食量、产蛋率、平均蛋重、料蛋比;48和52周龄时采集鸡蛋和血清测定蛋品质和血清生化指标;52周龄时采集粪便测定养分表观代谢率。 结果 与对照组相比,①2%脂肪粉组49~52周龄蛋鸡的平均日采食量显著提高(P<0.05)。②2%和4%脂肪粉组48周龄蛋鸡的蛋壳厚度显著降低(P<0.05),而52周龄的蛋比重显著提高(P<0.05)。③2%脂肪粉组48周龄蛋鸡血清中碱性磷酸酶活性显著提高(P<0.05),免疫球蛋白A含量显著降低(P<0.05)。④2%脂肪粉组52周龄蛋鸡血清中谷丙转氨酶活性、免疫球蛋白G含量显著提高(P<0.05),免疫球蛋白A含量显著降低(P<0.05)。 结论 添加2%和4%脂肪粉可以显著提高海兰褐蛋鸡采食量和蛋品质,但可能存在抑制脂质代谢的风险。本试验中脂肪粉的建议添加量为2%。

Abstract:

Objective This experiment aimed to investigate the effects of different levels of fat powder on the egg-laying performance, egg quality, serum biochemical indicators, and nutrient apparent metabolic rate of Hy-Line Brown laying hens, in order to provide a scientific basis for the application of fat powder in the feed ration of laying hens. Method A total of 270 Hy-Line Brown laying hens, aged 44 weeks, were selected and randomly divided into three groups, with six replicates per group and 15 hens in each replicate. The hens in control group were received a basic feed, while in the experimental groups were fed with 2% and 4% fat powder in the basic feed, respectively. The pre-feeding period was 1 week, and the experimental period was 8 weeks. The number of eggs, abnormal eggs and egg weight were recorded every day, and the feed consumption was recorded every week to calculate the average daily feed intake, egg production rate, average egg weight and feed-egg ratio. Eggs and serum were collected at 48 and 52 weeks of age to determine egg quality and serum biochemical indexes. Feces were collected at 52 weeks of age to determine the apparent metabolic rate of nutrients. Result Compared with control group, ①The mean daily feed intake of laying hens at 49-52 weeks of age was significantly higher in 2% fat powder group (P<0.05). ② Eggshell thickness was significantly lower at 48 weeks old in 2% and 4% fat powder groups (P<0.05), while egg specific gravity was significantly higher at 52 weeks old (P<0.05). ③Alkaline phosphatase activity was significantly higher (P<0.05), while the content of immunoglobulin A was significantly lower (P<0.05) in serum of 48 weeks old laying hens in 2% fat powder group. ④Glutamine aminotransferase activity and immunoglobulin G content were significantly increased (P<0.05), while immunoglobulin A content was significantly decreased (P<0.05) in serum of 52 weeks old laying hens in 2% fat powder group. Conclusion Addition of 2% and 4% fat powder significantly improved feed intake and egg quality in Hy-Line Brown laying hens, but there might be a risk of inhibiting lipid metabolism.Based on the results of this experiment, the recommended amount of fat powder to be added was 2%.
