| 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1mL0．75％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〉O．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〈O．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G1n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。

| Abstract: | 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 1ml 0.5%,1.0% and 1.5% glutamine solution 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 10.89% at day 7 post-hatch compared with that of control 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<0.05).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<0.05).And the plasma T3 concentration 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 broiler,injecting has no significant effect on egg hatching rate and hatching weight. |
