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。
孵化至18d的肉仔鷄活胚蛋240枚，隨機分成4箇處理組，每組6箇重複，每箇重複10枚蛋。處理組Ⅰ羊膜腔註射1mL0．75％生理鹽水作為對照，處理組Ⅱ、Ⅲ、Ⅳ分彆嚮羊膜腔內註射質量濃度為0．5％、1．0％、1．5％的穀氨酰胺營養液1mL。繼續孵化及齣殼後分析錶明：胚胎註射對胚蛋孵化率沒有影響（P〉0。05％）；胚胎註射穀氨酰胺對肉仔鷄齣殼重和齣殼重／蛋重無顯著影響（P〉O．05）；齣殼後第3天，試驗組體重較對照組有提高的趨勢（P〉0．05），齣殼後第7天，1．0％註射組體重比對照組提高10．89％（P〈0．01），1．5％註射組較對照組體重增加7．33％（P〈O．05）；3日齡肉仔鷄0．5％註射組血漿T4含量較對照組提高23．67％（P〈0．05）；7日齡肉仔鷄1．0％和1．5％註射組血漿T3含量比對照組分彆提高瞭36．63％和26．16％（P〈0．05）。總之，鷄胚註射G1n可促進肉仔鷄早期生長髮育，註射對胚蛋孵化率及齣殼重無明顯影響。

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.
