摘要

This paper investigated effects of replacing of wheat bran with a commercial fiber product started from different physiological periods of gestation on performance of sows.Total of 60 Landrace x Large Yorkshire primiparous sows were selected and randomly divided into five groups.The sows in the control group were fed with basic gestation diet with wheat bran as major source of crude fiher.Those in experimental groups Tl to T4 were fed with basic gestation diet followed by experiment diet with 2％ Arhocell(R)instead of wheat bran started from the 9lst day,6lst day,3lst day and lst day after mating,respectively.The result showed that average daily feed intake of sows decreased linearly and quadratically during gestation period and increased linearly and quadratically during lactation period as we gradually shift to earlier time to substitute dietary fiber Arbocell(R)for wheat bran.At the same time,delivery periods decreased linearly,wean to estrus intervals decreased linearly and quadratically,born alive and born weight increased linearly born alive percentage increased linearly,weaning alive and weaning weight tended to increase linearly,weaning rate tended to increase cubically,and average daily gain of piglets increased cubically,feces excretion time and feces weight of sows decreased linearly and cubically.The astriction scoring of sows decreased significantly.In conclusion,the alternative fiber product substitute for wheat bran is effective for sows' healthy production.The earlier the dietary fiher employed the better the sows' performance appeared.
