花生蔓与4种粗饲料间组合效应的研究
Associative Effects of Peanut Vine and Four Kinds of Roughages
摘要
Abstract
In order to investigate the associative effects of peanut vine (PV) and other roughages, combinations of PV with Leymus chinensis (LC) , corn stover silage (CS) , whole corn silage(WCS) and dry maize straw (DMS)were mixed in the ratio of 0:100, 20:80, 40:60, 60:40, 80:20 and 100:0, respectively. There were 3 replicates for each combination, and rumen fermentation in vitro was adopted to evaluate associative effects by analysis of gas production, gas parameter, gas production associative effects (AEGP) , microbial protein production, microbial protein associative effects (AEMCP) and synthetically associative effects (AEs). The results showed as follows: 1) in gas characteristics, different roughage combinations had significant difference in gas production parameters (P <0. 05). Gas production rate of PV was significantly higher than that of other four roughs, WCS had the greatest potential gas production and CS was next to it. 2) In AEGP, at 12, 24 and 48 h, both the 20 :80 ratio of PV to CS, PV to DMS, PV to LC, and the 40:60 ratio of PV to WCS had the highest positive associative effects (P <0. 01) , and the combination of PV with any one of the four roughs in ratio of 80:20 had the highest negative associative effects (P <0. 01 or P <0. 05). 3) In AEMCP at 48 h, all combinations had negative associative effects (P < 0. 01) , however, the combinations of PV with LC in ratio of 20:80 and 40:60 had positive associative effects (P <0.01) , and the 80:20 ratio of PV to LC had the highest negative associative effects (P <0. 01). 4) In AEs at 48 h, the 20:80 ratio of PV to CS, PV to DMS, PV to LC, and the 40:60 ratio of PV to WCS had the highest positive associative effects, while the combination of PV with any one of the four roughs in ratio of 80:20 had the highest negative associative effects. It is concluded that the combinations of PV with CS, DMS and LC in ratio of 20:80, and the combination of PV with WCS in ratio of 40:60 have the best associative effects in this experiment.关键词
