饲粮添加脯氨酸对妊娠环江香猪繁殖性能和血浆生化参数的影响
Effects of Dietary Proline Supplementation on Reproductive Performance and Plasma Biochemical Parameters of Pregnant Huanjiang Mini-Pigs
摘要
Abstract
This experiment was conducted to investigate the effects of proline metabolism on reproductive per-formance in pregnant Huanjiang mini-pigs and approach its underlying physio-biochemical mechanism.Fourty-eight female Huanjiang mini-pigs were used in this study.After 15-day of service, the animals were randomly assigned into 3 groups with 8 replicates per group and 2 pigs per replicate.The pigs in the three groups were fed the experimental diets supplemented with 0.77%L-alanine ( alanine group) , 1%L-proline ( proline group) , or 0.77%L-alanine +0.0167%2-difluoromethylornithine ( DFMO) ( DFMO group) in basal diet, respectively. After 45-day and 70-day of service, one sow per replicate was weighted and killed by bloodletting.Blood sam-ples were collected for analyzing biochemical parameters.The number of corpora luteum, fetus number and fe-tus weight were observed, by dissecting the sampled sows.The results showed as follows: the litter weight in proline group after 70-day of service was significantly higher compared with the alanine group ( P<0.05);after 45-day of service, the plasma glutamate pyruvate transaminase activity and albumn concentration in the proline group were significantly decreased compared with the alanine group ( P<0.05) .After 70-day of service, the plasma total cholesterol concentrations in the proline group, and high-density lipoprotein and albumin concen-trations in DFMO group were significantly decreased compared with 45-day post-service ( P<0.05) .The other parameters had no significant difference among three groups ( P>0.05) .It is concluded that dietary supplemen-tation with proline might increase the growth and development of fetus in pregnant sows via altering the metabo-lism of nitrogen and lipid during pregnancy.关键词
