摘要
豪猪的人工驯养在饲养方式上仍以玉米、瓜果等简单饲喂为主。试验旨在研究配合饲料对豪猪生长性能、血清免疫指标及软骨病的影响,为豪猪配合饲料的开发提供理论基础。试验采用单因素随机设计,选取3~5月龄体重相近的健康豪猪32头,随机分成两组,每组4个重复,每个重复4头,公母各半,预试期7 d,正试期60 d。其中试验组饲喂全价配合饲料,对照组饲喂原场饲料(80%的玉米+20%的黄豆)。试验结果表明:①试验组与对照组相比,豪猪的平均末重差异显著(P<0.05),平均日增重和料重比差异极显著(P<0.01)。②试验组豪猪血清中的总蛋白(TP)、白蛋白(ALB)和免疫球蛋白A(IgA)的含量均高于对照组,但差异不显著(P>0.05),血清中的免疫球蛋白G(IgG)和免疫球蛋白M(IgM)含量显著提高(P<0.05)。③对豪猪的软骨病发病率研究发现,试验组比对照组软骨病发病率降低了25%,差异显著(P<0.05)。综上,全价配合饲料能显著提高豪猪的生长性能和免疫功能,并降低软骨病的发病率。
The routine feeds for domesticating porcupine are simple,which mainly include corns,melons and fruits.The objective of this experiment was to explore the effects of formula feed on the growth per-formance,serum immune index and osteochondrosis of porcupine,and provide theoretical basis for the ex-ploitation of formula feed of porcupine.Thirty-two 3 to 5-month-old porcupines with a similar body weight were assigned to two groups randomly with 4 replications of 4 porcupines(2 males and 2 females each)according to a one-factor randomized design.The pre-test period lasted for 7 days,and the trail period lasted for 60 days.Porcupines in the test group were fed with complete formula feed,whereas those in the control group were fed with original feed which included 80%corn and 20%soybean.The results showed that:①the average final weight gain of porcupines in the test group was significantly higher than that in the control group(P<0.05),the average daily gain(ADG)and the feed/gain(F/G)com-parison between the test group and the control group,with a extremely significant difference observed(P<0.01).②Though the contends of the total pro-tein(TP),albumin(ALB)and immunoglobulin A(IgA)of serum increased in the test group,no sig-nificant difference was found between the two groups(P>0.05).The contends of immunoglobulin G(IgG)and immunoglobulin M(IgM)of serum of the test group were significantly higher than those of the control group(P<0.05).③Compared to the control group,the incidence of osteochondrosis of the test group decreased 25%,with a significant difference observed(P<0.05).In conclusion,the complete formula feed could significantly improve the growth performance and immunity,whereas decrease the incidence of osteochondrosis of porcupine.
