摘要
旨在研究中药渣对贵州黑山羊采食、反刍行为、腹泻率的影响。选取35只6~7月龄健康、体重相近的舍饲贵州黑山羊公羔羊,随机分成5组,每组7只,对照组饲喂基础发酵全混合日粮(FTMR),试验Ⅰ、Ⅱ、Ⅲ、Ⅳ组分别为添加30%、40%、50%、60%的中药渣替代基础日粮中部分粗饲料,混匀发酵制成FTMR饲喂,预试期5 d,正试期7 d。结果表明:1)对照组FTMR为深褐色,试验Ⅰ、Ⅱ组FTMR为浅褐色,而试验Ⅲ组FTMR为黄褐色,试验Ⅳ组为土黄色;各组FTMR随着中药渣添加量增高而酸香味逐渐浓郁,均未出现霉变,试验Ⅲ、Ⅳ组FTMR均发生粘连,轻度腐败。2)试验Ⅰ、Ⅱ组日均干物质采食量较对照组分别提高了12.16%、13.51%(P>0.05);试验Ⅱ组采食速度极显著高于试验Ⅰ、Ⅳ组和对照组(P<0.01);试验Ⅱ组采食率显著高于试验Ⅲ组(P<0.05),较对照组提高了20.34%(P>0.05);对照组昼夜采食时间(24 h)、昼采食时间、饮水时间和饮水次数极显著高于试验各组(P<0.01),躺卧、休息和睡眠时间极显著低于试验各组(P<0.01);试验Ⅲ、Ⅳ组排粪、排尿次数极显著高于试验Ⅰ组和对照组(P<0.01),试验Ⅱ组粪便颗粒均匀,粒度小,颗粒明显。3)试验Ⅰ、Ⅱ组昼夜反刍周期数、每反刍周期持续时间、昼夜反刍时间及昼反刍时间极显著高于对照组和其余试验组(P<0.01);试验Ⅱ组每个食团咀嚼次数和咀嚼时间极显著高于对照组和试验Ⅲ、Ⅳ组(P<0.01)。综上,40%中药渣FTMR品质优良,日粮适口性好,显著提高贵州黑山羊采食,促进贵州黑山羊反刍活动效果最佳。
This experiment was conducted to study the influences of sensory evaluation of fermented and wholly mixed diets with herbal medicine residues and their effects on driarrhea rate,feeding,and ruminant behavior of growing male lambs of Guizhou black goats.35 healthy,growing male lambs with similar body weights of housed Guizhou black goats were selected and randomly divided into 5 groups with 7 lambs per group.Lambs in the control group were fed with a basic diet,and those in four experimental groups were fed with a basic diet supplemented with 30%,40%,50% and 60% herbal medicine residues,respectively,to replace some roughage in the diet.The mixed diets were fermented to make FTMR for feeding.The pre-experimental period lasted for 5 days,and the experimental period for 7 days.The results showed as follows:1)The FTMR of Groups Ⅲ and Ⅳ all experienced adhesion and mild corruption.The FTMR of all the test groups was raised with the increase in the amount of traditional herbal medicine residues,with the sour flavor gradually getting stronger,but no mildew being observed.However,the FTMR of Groups Ⅲ and Ⅳ were sticky and mildly rotten.2)The average daily dry matter intake of Groups Ⅰ and Ⅱ was increased by 12.16% and 13.51%,respectively,compared with the control group(P>0.05);and their intake speed was significantly higher than that of Groups Ⅰ and Ⅳ group and the control group(P<0.01).Their feed intake rate was higher than that of Group Ⅲ(P<0.05),and was increased by 20.34%,compared with that of the control group(P>0.05).The diurnal feeding time(24 h),diurnal feeding time,drinking time and frequency of the control group were very significantly higher than those of the experimental groups(P<0.01),and their lying,resting and sleeping time were very significantly lower(P<0.01).The times of feces excrement and urination of Groups Ⅲ and Ⅳ were very significantly higher than those of Group Ⅰ and the control group(P<0.01),and the fecal pellets of Group Ⅱ were uniform and small in size,and evidently gr
