Effects of Microecological Preparation on Growth Performance for Broilers
摘要
Abstract
An experiment was carried out with a total of 280 1-day-old commercial broilers to investigate the effects of different dietary microecological preparation source and level on growth performance. Birds were randomly assigned by body-weight to one of 7 treatments (five pen replicates of eight chicks each). The test design for earlier stage (1 to 21 d) and later stage (22 to 42 d) , and all groups shared one control group. The results showed that dietary microecological preparation significantly affected (P<0. 05) the ADFI and ADG, but no differences among microecological preparation sources in above indices during 1 to 21 d (F>0. 05). During 22 to 42 d, compared with the control group, ADG and F/G was significantly affected by the microecological preparation I and II (P<0. 05), ADG increased linearly (P<0. 05) and F/G significantly decreased as dietary microecological preparation level increased (P<0. 05). For the whole staged to 42 d), microecological preparation significantly affected (P<0. 05) the ADG and F/G, ADG increased linearly (P<0. 05) and F/G decreased linearly (P<0. 05) as microecological preparation supplement level increased. In conclusion, supplementation of microecological preparation improved the growth performance of broilers.关键词
