【摘要】：本试验旨在通过研究饲粮粗蛋白质水平对济宁百日鸡蛋品质和血清生化指标的影响,为确定济宁百日鸡适宜蛋白质需要量提供试验依据。采用单因素完全随机试验设计,选用体重相近、健康的40周龄济宁百日鸡产蛋鸡525只,随机分为5组,每组5个重复,每个重复21只鸡。各组分别饲喂粗蛋白质水平为13%、14%、15%、16%和17%的试验饲粮。预试期7 d,试验期56 d。结果表明:1)饲粮粗蛋白质水平显著影响了蛋重(P0.05)。在一定的饲粮粗蛋白质水平范围(13%~16%)内,蛋重有随着饲粮粗蛋白质水平的升高而升高的趋势。16%粗蛋白质水平组蛋重最大。2)饲粮粗蛋白质水平显著影响了44周龄的血清总蛋白(TP)、白蛋白(ALB)、尿酸(UA)含量及48周龄血清尿素(UREA)含量(P0.05),但并未产生规律性的变化。综合试验结果,济宁百日鸡41~48周龄饲粮粗蛋白质水平不宜高于16%。
[Abstract]:The purpose of this experiment was to study the effect of dietary crude protein level on egg quality and serum biochemical indexes in Jining, and to provide experimental basis for determining the appropriate protein requirement of Jining hundred day chickens. A single factor complete random trial design was used to select 525 healthy 40-week-old Jining 100-day laying hens with similar body weight. They were randomly divided into 5 groups with 5 replicates in each group and 21 chickens per replica. Each group was fed with 13% crude protein and 17% crude protein. The pretest period was 7 days and the trial period was 56 days. The results showed that the dietary crude protein level significantly affected the egg weight (P0.05). Within a certain dietary crude protein level, Egg weight has a tendency to increase with the increase of dietary crude protein level. 16% crude protein level group has the largest egg weight. 2) dietary crude protein level significantly affected the serum total protein TPN, albumin, ALBN, uric acid UAA content and 48 weeks of age at 44 weeks of age. The content of urea urEAA in serum of age was 0. 05%, but it did not change regularly. The results showed that the dietary crude protein level of Jining hundred Chicken at the age of 41 ~ 48 weeks should not be higher than 16 ~ (th).
