[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.
