Effects of Different Energy Sources on Growth Performance,Age of Puberty,and Uterus and Ovarian Development for Wuzhishan Pigs
摘要
Abstract
The main objective of the present study was to investigate the effects of different energy sources on growth performance,age of puberty, and uterus and ovarian development for Wuzhishan pigs.According to single factor experiment design, thirty Wuzhishan sows with similar bodyweight were assigned to three groups.Piglets in three groups were fed diets supplemented with 5% cassawa starch,3% coconut oil,and 3% coconut oil+0.8% flaxseed meal.The results showed that piglets fed diet supplemented with 3% coconut oil and 3% coconut oil+0.8% flaxseed meal had higher average daily gain (ADG)(P<0.05) of 5 kg~puberty phase.Supplementation with 3% coconut oil significantly increased back fat thickness(P<0.05), and influenced the age at puberty which was 9±3.1 and 8±1.8 days earlier than that of 3% coconut oil+0.8% flaxseed meal and 5% cassawa starch groups(P<0.05).Compared with other two groups, the weights of uterus, uterine horn, and uterine body length(P<0.05) during puberty were significantly increased in coconut oil group.The fallopian tube length(P<0.05) was higher in 3% coconut oil and 3% coconut oil +0.8% group than 5% cassawa starch group.Supplementation with 3% coconut oil +0.8% flaxseed meal significantly increased large follicles(P<0.05).These results suggest that the addition of fat rich diet for Wuzhishan pig could improve the growth performance, increase back fat thickness and facilitate puberty onset, pectin rich diet could enhance ovulation.关键词
