【摘要】：试验利用新的锌源、锰源(氨维乐?锌170,氨维乐?锰150),研究有机锌和有机锰对蛋种母鸡生产性能、血液生化指标及其后代雏鸡骨骼发育和肠道结构完整性的影响,探讨有机锌、锰对蛋种母鸡生产性能影响的机制,为今后在家禽中应用提供理论依据和实践参考。试验选取576只体重相近的23周龄健康海兰褐D系蛋种母鸡,随机分为3个处理,每个处理12个重复,每个重复由连续8个笼组成,每笼2只蛋种母鸡;选取60只体重相近的23周龄健康海兰褐C系蛋种公鸡,随机分为3个处理,每个处理10个重复,每个重复2只蛋种公鸡。对照组(A)日粮添加80mg/kg的硫酸锌、硫酸锰,等量添加组(B)日粮用40mg/kg的有机锌、锰替换A组日粮40mg/kg的硫酸锌、锰,额外添加组(C)日粮在A组日粮的基础上额外添加40mg/kg的有机锌、锰。试验期为32周。试验结果表明:1)蛋种母鸡生产性能指标:日粮中添加有机锌、有机锰,对蛋种母鸡的体重和体增重没有产生显著影响(P0.05);试验全期平均蛋重,等量添加组显著高于对照组(P0.05),与额外添加组没有显著差异(P0.05);试验第9、24周蛋种母鸡饲养日产蛋率产生影响,额外添加组极显著高于对照组(P0.01),试验第2、4周入舍鸡产蛋率产生影响,对照组显著高于等量添加组(P0.05),与额外添加组没有显著差异(P0.05),其他周的饲养日产蛋率和入舍鸡产蛋率没有显著差异(P0.05);额外添加组的破蛋率显著低于等量添加组(P0.05),极显著低于对照组(P0.01);试验第8、24周,等量添加组蛋壳强度显著大于额外添加组(P0.05),与对照组差异不显著(P0.05),试验第16周,等量添加组蛋形指数和相对蛋白高度显著大于对照组和额外添加组(P0.05),试验第24周,额外添加组哈夫单位显著高于对照组(P0.05),其他试验周,各组哈夫单位没有产生显著差异(P0.05);蛋壳黄度(b值)不受日粮中添加有机锌、有机锰的影响(P0.05),与对照组相比,等量添加组显著降低第8周和32周蛋壳亮度(P0.05),降低24周蛋壳红度而提高32周蛋壳红度(P0.05),额外添加组显著提高32周蛋壳红度(P0.05);与对照组相比,等量添加组显著降低第24周蛋黄比重(P0.05),与额外添加组没有显著差异(P0.05),其他试验周的蛋黄比重均没有发生显著变化(P0.05);试验第24周,等量添加组健雏率显著高于对照组和额外添加组(P0.05)。2)蛋重母鸡生理生化指标:日粮中添加有机锌、有机锰,试验第8、16、32周蛋黄锰含量发生变化,试验第8周,等量添加组蛋黄锰含量显著高于额外添加组(P0.05),试验第16周,额外添加组蛋黄锰含量显著高于对照组(P0.05),试验第32周,等量添加组蛋黄锰含量极显著高于对照组和额外添加组(P0.01);没有对蛋种鸡血液抗氧化酶活性和细胞免疫功能产生显著影响(P0.05)。3)雏鸡检测指标:蛋种鸡日粮中添加有机锌、有机锰,对雏鸡胫骨锌的含量没有显著影响(P0.05),对雏鸡胫骨中锰的含量产生显著或极显著影响(P0.05或P0.01);试验第23周,等量添加组雏鸡的胫骨长度显著大于对照组和额外添加组(P0.05),试验第32周,等量添加组雏鸡胫骨重量显著轻于对照组(P0.05),其它试验周,各组胫骨长度和胫骨重量没有显著差异(P0.05);与对照组相比,等量添加组雏鸡回肠紧密连接蛋白claudin-1 m RNA的表达水平显著显著上调(P0.05);额外添加组肝脏中Mn-SOD的活性显著高于对照组(P0.05),等量添加组与对照组和额外添加组没有显著差异(P0.05),各组雏鸡肝脏总SOD和Cu/Zn-SOD没有显著差异(P0.05)。结论:在本试验条件下,添加有机锌锰,在一定程度上可以改善蛋种鸡的生产性能,提高后代组织中锰的沉积。其中等量添加组的作用效果最佳。
[Abstract]:The test using a new source of zinc, manganese source (ammonia welove? Zinc 170, ammonia welove? Mn 150), the research on egg production performance of organic zinc and organic manganese, blood biochemical indexes and influencing offspring chicks skeletal development and intestinal structural integrity, to explore the mechanism of organic zinc and manganese effects on eggs of hens the production performance, and provide a theoretical basis and practical reference for future application in poultry. The test selected 576 weight similar 23 week old hy line brown D line egg hen, were randomly divided into 3 treatments with 12 replicates of each replicate by 8 consecutive cage, 2 eggs for each cage hen; a total of 60 similar weight 23 week old hy line brown C line egg chicken, were randomly divided into 3 treatments with 10 replicates of 2 birds per replicate egg rooster. The control group (A) dietary zinc sulfate, manganese sulfate, 80mg/kg group (B), equivalent to add organic the 40mg/kg diet with zinc, Zinc, manganese sulfate to replace the A diet 40mg/kg group added manganese (C) organic zinc diets based on A diets on the addition of 40mg/kg manganese. The experiment lasted for 32 weeks. The results showed that: 1) the egg production performance index: adding organic zinc in diet organic manganese, hen on egg weight and body weight had no significant effect (P0.05); test the average egg weight, amount of added group was significantly higher than control group (P0.05), there was no significant difference with the addition of group (P0.05); test the 9,24 week egg hen feeding Nissan egg rate influence. The extra group was significantly higher than control group (P0.01), test the 2,4 week into homes chicken egg production rate influence, the control group was significantly higher than that of equivalent add group (P0.05), there was no significant difference with the addition of group (P0.05), the other week feeding rate and Nissan eggs into homes from chicken egg rate (no significant difference P0.05); additional group Brokening rate was significantly lower than the amount added group (P0.05), was significantly lower than the control group (P0.01); test the 8,24 weeks group was significantly greater than the equivalent added eggshell strength added group (P0.05), no significant difference with control group (P0.05), a sixteenth week trial, with added group of egg shape index and relative protein were highly significant. Than the control group and added group (P0.05), a twenty-fourth week trial, additional group Haugh unit was significantly higher than the control group (P0.05) and other test each week, Haugh unit had no significant difference (P0.05); eggshell yellowness (b value) is not affected by the addition of organic zinc in diet, the effect of organic manganese (P0.05), compared with the control group, equal amount group significantly decreased by eighth and 32 weeks (P0.05), eggshell brightness decreased at 24 weeks and 32 weeks to improve red eggshell eggshell red (P0.05), additional group significantly increased 32 weeks of red shell (P0.05); compared with the control group, equal amount significantly reduce Twenty-fourth weeks of egg yolk proportion (P0.05), there was no significant difference with the addition of group (P0.05) and other test week egg yolk proportion did not change significantly (P0.05); a twenty-fourth week trial, equal rate of Healthy Chicks added group was significantly higher than that of control group and added group (P0.05).2): physiological and biochemical indexes of hen egg weight the addition of organic zinc, dietary organic manganese, manganese content test in 8,16,32 weeks of egg yolk change test for eighth weeks, with added group was significantly higher than that of egg yolk manganese content added group (P0.05), a sixteenth week trial, additional group manganese content of egg yolk was significantly higher than the control group (P0.05), a thirty-second week trial, equal amount the manganese content of yolk was significantly higher than control group and added group (P0.01); no significant impact on the egg chicken blood antioxidant enzyme activity and cellular immune function (P0.05).3) chicks detection index: add organic zinc, chicken eggs in the diet of organic manganese, chicken The content of tibia zinc had no significant effect (P0.05), the content of manganese in chicken tibia affected significantly or very significantly (P0.05 or P0.01); the twenty-third week experiment, add chicken tibia length equivalent group was significantly higher than that of control group and added group (P0.05), a thirty-second week trial, adding chicks tibia weight were equivalent lighter than the control group (P0.05) and other test each week, tibia length and tibia weight had no significant difference (P0.05); compared with the control group, the expression level of chicken ileum group equal amount of tight junction protein claudin-1 m RNA was significantly increased (P0.05); addition of Mn-SOD group activity in liver was significantly higher than the control group (P0.05), equivalent to add additional group and control group and there was no significant difference (P0.05), there was no significant difference between the groups of chicken liver total SOD and Cu/Zn-SOD (P0.05). Conclusion: under the conditions of this experiment, organic zinc manganese, in a certain It can improve the production performance of egg laying hens and increase the deposition of manganese in the tissues of the offspring, among which the effect of the equal addition group is the best.
