摘要/Abstract

摘要： 为了探讨在反刍动物中等或较低水平粗饲料中需要添加能量和蛋白质饲料的量和比例,试验采用体外产气法测定玉米、菜粕和小麦秸或氨化小麦秸在不同精粗比(70∶30,60∶40,50∶50,40∶60,30∶70)和菜粕水平(6%,12%,18%,24%)下各组合及4种饲料分别培养2,4,6,9,12,24,36,48,72,96 h内的产气量,并通过24 h产气量和各组合的加权估算值计算出各组合的组合效应值。结果表明:1)小麦秸基础料中,15个饲粮组合为负组合效应,而高精粗比70∶30高菜粕水平18%和24%两组合和低精粗比40∶60低菜粕水平6%和12%两组合均表现出正组合效应,且高精粗比70∶30的组合效应值极显著高于低精粗比40∶60和30∶70组(P<0.01)。2)氨化小麦秸基础料中,19个饲粮组合均不同程度地表现出正组合效应值。各精粗比间组合效应值,30∶70组极显著高于70∶30组(P<0.01)。各菜粕水平间组合效应值,24%组显著高于12%组(P<0.05)。低精粗比和高菜粕水平组合时组合效应值最大。使用氨化小麦秸要比使用小麦秸更能充分利用粗饲料,节省精饲料。

Abstract: To evaluate the amount and proportion of added energy feed and protein feed,the effects of concentrate-roughage ratio (C∶R) and rapeseed meal supplementation level on associated effects of diets in vitro were studied. Wheat straw (WS) or ammonium bicarbonate treated wheat straw (ABWS) basal diet was supplemented with a mixture of rapeseed meal (RSM) and corn. The ratios of RSM and corn to WS or ABWS tested were 70∶30,60∶40,50∶50,40∶60,and 30∶70,with the proportion of RSM at 6%,12%,18%,24% in the whole diet. Gas production (GP) was recorded at 0,2,4,6,9,12,24,36,48,72,and 96 h. AE was defined as the difference between the observed in vitro GP and the predicted value from individual feed fermented alone. 1) Negative AE was observed under the WS basal diet in 15 groups. When the concentrate-roughage ratio was 70∶30 and the RSM content was 18% and 24%,a positive AE was observed. When the concentrate-roughage ratio was 40∶60 and the RSM content was 6% and 12%,positive AE were observed. The AE of the high C∶R group 70∶30 was significantly higher than that of the low C∶R groups 40∶60 and 30∶70 (P<0.01). 2) A positive AE was observed in ABWS basal diets in all mixtures except one group. The AE of the C∶R group of 30∶70 was significantly higher than that of the C∶R group of 70∶30 (P<0.01). The AE proportion at RSM 24% was significantly greater at RSM 12% (P<0.05). It is concluded that the AE is largest in the group with low C∶R and a high proportion of RSM. ABWS is better than WS in saving concentrated feed.
