摘要
孵化至18d的肉仔鸡活胚蛋240枚,随机分成4个处理组,每组6个重复,每个重复10枚蛋。处理组Ⅰ羊膜腔注射1mL 0.75%生理盐水作为对照,处理组Ⅱ、Ⅲ、Ⅳ分别向羊膜腔内注射质量浓度为0.5%、1.0%、1.5%的谷氨酰胺营养液1mL。继续孵化及出壳后分析表明:胚胎注射对胚蛋孵化率没有影响(P>0.05%);胚胎注射谷氨酰胺对肉仔鸡出壳重和出壳重/蛋重无显著影响(P>0.05);出壳后第3天,试验组体重较对照组有提高的趋势(P>0.05),出壳后第7天,1.0%注射组体重比对照组提高10.89%(P<0.01),1.5%注射组较对照组体重增加7.33%(P<0.05);3日龄肉仔鸡0.5%注射组血浆T4含量较对照组提高23.67%(P<0.05);7日龄肉仔鸡1.0%和1.5%注射组血浆T3含量比对照组分别提高了36.63%和26.16%(P<0.05)。总之,鸡胚注射Gln可促进肉仔鸡早期生长发育,注射对胚蛋孵化率及出壳重无明显影响。
In this study, 240 hatching broiler eggs at 18-d incubation were randomly divided into 4 treatments with 6 replicates of 10 eggs each. Eggs in treatment One were injected with 1 m ml 0.75 % physiological saline into amniotic cavity as control, and those in treatment Two, Three and Four were injected into amniotic cavity with lml 0.5%, 1.0% and 1.5% glutamine solu- tion respectively. The results showed ：No effects of in ovo glutamine feeding on hatching rate. No significant effects of the in ovo feeding of glutamine of post-hatch broiler weight and post-hatch broiler weight / egg weight （ P 〉0.05）. At day 3 post- hatch broiler, the body weights in test groups are increased in comparison with those of the control group （ P 〉0.05）. The body weight of broilers in ovo fed with 1.0% glutamine is increased by 10. 890% at day 7 post-hatch compared with that of con- trol group （ P 〈0.01）. The body weight of broilers in ovo fed with 1.5 % glutamine group is increased significantly by 7.33 % compared with that of the control group （ P d0.05）. The plasma T4 concentration of 3-day-old broilers treated with 0.5 % glutamine is increased significantly by 23.67 % compared with that of control group （ P d0.05）. And the plasma T3 concentra- tion of 7-day-old broilers in ovo treated with 1.0%and 1.5 % glutamine rose respectively by 36.63 % and 26.16% compared with the control group （P〈0.05）. In short, in ovo glutamine feeding can promote the early growth and development of broil- er, injecting has no significant effect on egg hatching rate and hatching weight.
