Effects of Dry and Wet Feeding Methods on the Behavior Change and ProductionPerformance of Small-tailed Han Sheep
摘要
Abstract
This experiment was conducted to investigate the effects of dry and wet feeding methods on the behavior change and production performance of Small-tailed Han sheep.30 non-pregnant Small-tailed Han sheep with good body condition and similar weight of 1 year old were selected and randomly divided into two groups with 3 replicates each group and 5 sheep per replicate.Group A were fed dry wheat straw, group B were fed wet wheat straw.Feeding experiments were conducted for 43 d.The behavior changes of each group were observed and recorded within 24 h by a 24-hour camera in 20 d~23 d and digestive experiments were conducted for 7 days after the formal experiment period.The results showed as follows: (1) the standing and reposing time had a difference of 44.66 min(P>0.05), however, standing time and the ingestion time of group B respectively reduced by 5.17% (P>0.05)and 82.34% (P<0.05), while the rumination time increased by 3.38%(P>0.05) than group A;(2) the DMI and apparent digestibility of nutrients had no significant difference between two groups, but daily roughage intake of group A increased by 4.22% than group B, while apparent digestibility of nutrients had a decrease trend;(3) there was no significant difference of ADG and FCE of concentrate supplement between group A and group B(P>0.05), however, the ADG and FCE of concentrate supplement of group B increased by 9.74% compared with group A, while economic benefits improved 2.84% compared with group A.关键词
