摘要: 试验旨在研究青贮甘蔗尾(sugarcane tops silage,SS)和青贮玉米秸秆(corn straw silage,CS)对生长水牛生长性能、消化代谢及血液生化指标的影响。试验1:选择21头体重、胎次相同或相近的6月龄生长水牛,随机分为3个组,分别饲喂SS+精料、CS+精料、SS+CS+精料,进行为期30 d饲养试验。试验2:另选6头体重、胎次相同或相近的6月龄生长水牛随机分为2组,分别饲喂SS和CS,不喂精料,利用全收粪法进行为期4 d的消化代谢试验。结果表明:①SS和CS单独饲喂对生长水牛平均干物质采食量(ADMI)影响不显著(P>0.05),饲喂CS组生长水牛平均日增重(ADG)较SS组高,差异不显著(P>0.05)。二者组合饲喂时生长水牛ADMI、ADG比其单独饲喂时高。②CS的养分消化率、氮代谢和能量代谢率均高于SS,但差异均不显著(P>0.05),二者中性洗涤纤维(NDF)和酸性洗涤纤维(ADF)消化率差异不显著(P>0.05)。③SS和CS对生长水牛血液生化指标影响差异均不显著(P>0.05),对动物机体无不良影响。由此可见,单独饲喂时CS养分消化率较SS高,CS及SS对生长水牛血液生化指标均无不良影响,且二者组合饲喂能提高生长水牛生长性能。

Abstract: The objective of this work was to investigate the effects of sugarcane tops silage and corn straw silage on the growth performance, digestibility and metabolisability of nutrient and blood biochemical indexes of growing buffalo.Trial 1:21 buffalos were randomly divided into 3 groups according to the principle of body weight and birth similarity for 30 days feeding trial.The buffalos in 3 groups were fed with SS+concentrate, CS+concentrate and SS+CS +concentrate, respectively.Trial 2:Six buffalos were randomly divided into 2 groups according to the principle of body weight and birth similarity, and fed with SS and CS, respectively.There were 4 days for digestion-metabolism trial using total feces collection methods.The results showed that:①There were no significant difference on average dry matter intake(ADMI)of buffalos fed with CS and SS(P>0.05), but comparing with SS, the average daily gain(ADG)was higher of buffalos fed with CS(P>0.05).Both ADMI and ADG were higher when buffalos fed with CS+SS.②Compare to SS, the nutrient digestibility, nitrogen metabolization and energy metabolic rate of CS were higher.And the effects of SS and CS on the digestibility of NDF, ADF were no significant difference(P>0.05).③The effect of feeding with CS, SS on blood biochemical indexes were no significant difference, and did not have any bad effect on animal body.Thus the digestibility of nutrient was higher when fed with CS, and SS and CS separately had no bad effect on blood biochemical indexes.Feeding SS+CS could improve the growth performance of growing buffalo.
