摘要
本试验研究了日粮中氧化鱼油及抗氧化剂对父母代种母鸡繁殖性能及对后代仔鸡的影响,旨在研究父母代营养对后代的影响。200只29周龄Cobb-Avian 48父母代种母鸡分为5个处理,每个处理5个重复,每个重复8只鸡,种鸡日粮分别为2%新鲜鱼油(FO)组、2%氧化鱼油组(OFO)、2%OFO+100 mg.kg-1VE、2%OFO+198mg.kg-1乙氧喹(EMQ)组、2%OFO+100 mg.kg-1VE+198 mg.kg-1EMQ组,后代的仔鸡饲喂完全相同的玉米—豆粕型日粮。结果表明:(1)父母代种母鸡日粮中氧化鱼油降低了母鸡产蛋率(P<0.05),入舍母鸡产蛋量(P<0.05);(2)父母代种母鸡日粮中氧化鱼油降低了后代仔鸡初生体质量(P<0.05);(3)父母代种母鸡日粮中各个氧化鱼油组的后代仔鸡空肠绒毛高度变短(P<0.01),绒毛宽度变窄(P<0.01);(4)父母代种母鸡日粮中氧化鱼油降低了后代仔鸡0～7日龄平均增加体质量(P<0.01)、7日龄平均体质量(P<0.05),7～14日龄的平均采食量(P<0.01),14日龄平均体质量(P<0.01)。结果提示,父母代种母鸡日粮中氧化鱼油具有明显的繁殖毒性,不仅降低了父母代种母鸡的繁殖性能,而且通过影响子代初生体质量以及肠道黏膜的发育,最终导致生长性能下降。
This experiment was conducted to investigate effects of oxidized oil and antioxidant supplementation in breeder hen diet on reproduction performance of the breeders and maternal effects to the offspring.A total of 200 Cobb-Avian 48,29 weeks old broiler breeder hens were assigned randomly to 5 groups with 5 replicates of 8 birds.Each group was fed one of the following diets;2% fish oil（FO）,2% oxidized oil（OFO）,2% OFO＋100 mg·kg-1 VE,2% OFO＋198 mg·kg-1 EMQ,2%OFO＋100 mg·kg-1VE＋198 mg·kg-1 EMQ,the progeny broilers were fed the same diet.The results showed that：（1） Inclusion of OFO in the breeder hens′ diet reduced laying percentage（P0.05） and egg production（P0.05）of the breeders;（2） OFO in the breeder hens′ diet reduced neonatal offspring chick weight of the breeders（P0.05）;（3） Offspring chicks from the dam feeding oxidized oil had shorter jejunum villus height（P0.01） and thinner jejunum villus width（P0.01）;（4） OFO in the breeder hens′ diet reduced Body weight gain of 0-7 d（P0.01）,body weight at 7 d（P0.05）,feed intake of 7-14 d（P0.01） and body weight at 14 d（P0.01） of the offspring broilers.These data indicated that oxidized oil had obvious toxicity to the breeder hens,not only reduced the reproduction performance of the breeder hens,but also decreased the neonatal offspring chick body weight,injuried the morphology of the jejunum of offspring chicks,resulted in decreased offspring performance.
