日粮粗纤维水平对妊娠母猪繁殖性能的影响
The Effect of Dietary Crude Fiber Levels on Reproductive Performance of Sows
摘要
Abstract
This experiment was conducted to study the effects of dietary fiber levels on reproductive performance of sows.Thirty PIC sows,with similar parity and breeding time,were randomly divided into 5 groups.They were fed during pregnancy with 3%,5%, 7%,9% and 11% of crude fiber on food,and made the intake of energy,protein,calcium,phosphorus and other basically the same by adjusting the amount fed each group.The results show that：1）During pregnancy,9% crude fiber group increased the backfat thickness was significantly higher than 3%、5%、7% and 11% crude fiber groups（P0.05）,the average weight gain was significantly higher than11% fiber group（P0.01）,and 3%、5%、7% crude fiber groups（P0.05）;2）The backfat thickness in the 9% fiber group was significantly thinner than the other groups in the lactation（P0.05）,was reduced by 1.50 mm、0.66 mm、0.83 mm and 0.83 mm,the average weight loss were reduced by 5.77 kg、2.60 kg、0.87 kg and 0.68 kg;3）9% crude fiber group,the average little size,was increased significantly（P0.01）,compared with 3%,5%,7%,9% and 11% crude fiber group were increased by 2.33、1.00、0.83 and 1.33,the average 28th days weaning weight was significant higher than others group（P0.01）,specific values were 12.16 kg、8.63 kg、7.91 kg and 5.68 kg.The results show that increased levels of crude fiber diet of pregnant sows to maintain sow body condition and improve reproductive performance,when the crude fiber content of 9%,the effect is most significant.关键词
