摘要: 【目的】探究饲粮中添加有机锰铁铜锌复合制剂产品对蛋鸡生产性能、血液生化指标、卵泡发育和胫骨质量的影响,为有机锰铁铜锌复合制剂产品在产蛋高峰期蛋鸡饲粮中的科学应用提供参考。【方法】选取产蛋率相近的270只38周龄京粉蛋鸡,随机分为3个处理组,每组6个重复,每个重复15只鸡。对照组蛋鸡饲喂玉米-豆粕基础饲粮,试验组蛋鸡分别饲喂在基础饲粮中添加50% NCR(1994)推荐量的有机锰铁铜锌复合制剂产品1和2(OT1、OT2)的饲粮。预试期1周,正试期12周。每天记录产蛋情况,每周结料。在第4、8和12周,测定鸡蛋品质。试验结束时,每个重复随机选取1只蛋鸡,采集血液,测定血常规、血清生化和抗氧化指标,屠宰后测定回肠免疫指标,输卵管和卵泡发育指标及胫骨质量。【结果】与对照组相比,OT1显著提高了第8周蛋鸡蛋壳厚度(P<0.05);OT1、OT2显著降低了蛋鸡血小板数并提高了血清中总蛋白(TP)含量(P<0.05),OT2显著提高了蛋鸡血清中碱性磷酸酶(ALP)活性(P<0.05),OT1显著提高了蛋鸡血清中谷胱甘肽过氧化物酶(GSH-Px)活性(P<0.05);OT1、OT2显著提高了蛋鸡回肠黏膜中免疫球蛋白A(IgA)含量(P<0.05),OT2显著提高了回肠黏膜中IgG含量(P<0.05);OT1、OT2对蛋鸡输卵管和卵泡发育均无显著影响(P>0.05);OT1、OT2显著提高了蛋鸡胫骨长度(P<0.05)。【结论】在本试验条件下,饲粮中添加有机锰铁铜锌复合制剂产品不影响蛋鸡生产性能,但提高了蛋鸡血清抗氧化能力、肠道免疫功能和胫骨质量,其中饲粮中添加有机锰铁铜锌复合制剂产品1效果较佳。

Abstract: 【Objective】 This research was aimed to evaluate the effects of dietary organic manganese-iron-copper-zinc compound preparations on the production performance,blood biochemical indexes,follicle development and tibia quality of laying hens,so as to provide reference for the scientific application of organic manganese-iron-copper-zinc compound preparations in diets of laying hens during the laying peak period.【Method】 A total of 270 Jingfen hens aged 38 weeks were randomly assigned to 3 dietary groups,each with 6 replicates of 15 hens.Hens in control group were supplied with corn-soybean basal diet,and hens in experimental groups were fed the basal diet supplemented with 50% NCR (1994) recommended amounts of organic manganese-iron-copper-zinc compound preparation products 1 and 2 (OT1 and OT2),respectively.This study included a 1-week pre-trial period followed by a 12-week experimental period.The egg production was recorded every day,and the feed weekly.At weeks 4,8 and 12,egg quality was determined.At the end of the feeding,one layer per replicate was selected,blood sample was collected,blood routine,blood biochemical and antioxidant indices were measured,and the ileum immunity indices,oviduct and follicular development indexes and tibia quality were determined after slaughter.【Result】 Compared with control group,OT1 significantly increased the eggshell thickness of laying hens at weeks 8 (P<0.05);OT1 and OT2 significantly decreased the platelet count and increased total protein (TP) content in serum of laying hens (P<0.05),OT2 significantly increased the alkaline phosphatase (ALP) activity in serum of laying hens (P<0.05),OT1 significantly increased the glutathione peroxidase (GSH-Px) activity in serum of laying hens (P<0.05).OT1 and OT2 significantly increased immunoglobulin A (IgA) content in ileum mucosa of laying hens (P<0.05),OT2 significantly increased IgG content in ileum mucosa of laying hens (P<0.05).OT1 and OT2 had no significant effect on the oviduct and follicular development of laying hens (P>0.05).OT1 and OT2 significantly increased the tibial length of laying hens (P<0.05).【Conclusion】 Under the conditions of this experiment,the organic manganese-iron-copper-zinc compound preparation had no effect on the production performance of laying hens but improved the antioxidant capacity in serum,intestinal immune function and tibia quality.Among the two preparations,organic manganese-iron-copper-zinc compound preparation product 1 demonstrated superior efficacy.
