| 摘 要： | 本试验将90枚孵化第18天的落盘肉仔鸡胚蛋随机分为3组,分别向羊膜腔注射0.5mL复合氨基酸溶液、0.5mL生理盐水和不注射(对照组),研究对孵化率和后期胚胎生长的影响。结果显示:各处理组间的孵化率和出壳体重无显著差异(P>0.05),但出壳重与第18天胚蛋重的比值有显著差异(P<0.05),注射氨基酸组比对照组增加2.3%。这些结果表明鸡胚给养氨基酸可有效增加肉鸡出壳重。

| Abstract: | In order to examin the effect of in ovo feeding amino acid(AA)on hatchability and embryonic growth of broiler,90 eggs of 18 d incubation were divided into 3 groups,each group was injected with AA solution 0.5 mL,NaCl saline 0.5 mL ,or no injection(control).The results showed there were no significant differences(P > 0.05)in hatchability and body weight(BW) of hatched chick among all treatments.However,hatching BW relative to egg weight of 18 d incubation was significantly increased by 2.3 %(P < 0.05)when AA solution was injected.The results suggested that in ovo administration of AA could be an effective method in improving chick's BW at hatch. |
