夏季发酵床饲养模式对断奶仔猪生长性能、血清生化指标及猪舍环境的影响
Effects of Deep-Litter Systems on Growth Performance, Biochemical Parameters and Swine House Environment in Weaned Piglets in Summer
摘要
Abstract
[Objective] The objective of this study was to investigate the effects of deep-litter systems on growth performance, biochemical parameters and swine house in weaned piglets in summer. [ Method ] A total of 300 piglets weaned at (28±3) days of age were randomly allocated into 2 treatments: traditional concrete-based house (TCBH) and deep-litter house (DLH). There were five replicates for each treatment and thirty piglets in each replicate. The experiment was lasted for 42 days. Body weights and feed intakes were measured every 14 days through the study. Temperature and relative humidity were measured every day. Blood samples were collected from four piglets from each replicate for biochemical parameters assay on the 15th, 29th and 43rd days. Air samples were collected for determination of the ammonia concentration in house from 29th to 35th days and from 36th to 42nd days.[Result] Average daily gain (ADG) of piglets in DLH group was higher (/><0.05) compared with the TCBH group. Diarrhea ratio of piglets in DLH group was lower than those of TCBH group (P<0.05) from 1st to 14th, 1st to 28th and 1st to 42nd days. There was no significant difference in average daily feed intake (ADFI) between the TCBH group and DLH group. Ammonia concentration in DLH group was lower (P<0.05) compared with the TCBH group at 7:00 clock during the experiment days. There was no significant difference in air temperature and relative humidity between the TCBH group and DLH group (/>>0.05) .On the 14th and 28th days, the activity of alanine transarninase (ALT) in serum of DLH group was lower than that of TCBH group (P<0.05), there was no significant difference in glutamic-oxal(o)acetic transaminase (AST) and alkaline phosphatase (ALP) activities in serum between the TCBH group and DLH group (P>0.05). The content of glucose (GLU) and triglycerides (TG) in serum of DLH group was lower than that of TCBH group (P<0.05) on 15th, 29th, and 43rd days. [Conclusion] The results demonstrated that deep-litter systems could decrease the activity ALT and decrease the content of TG and GLU in serum in summer. Deep-litter systems, which had no negative effect on growth performance of piglets and swine house environment, was suitable for weaned piglets production under the conditions of this experiment.关键词
