养殖与饲料2024年第2期13江汉水牛生产性能及经济效益研究韩安勤,黄彬,黄祥春,李必圣,李友全,伍万宏湖北省畜牧良种场,湖北荆州434010摘要【目的]研究江汉水牛的主要体尺指标和生产性能,为江汉水牛保种和开发利用提供理论依据。[方法]测定20头2.5岁左右、平均体质量(360±59)kg江汉水牛(公牛10头、母牛10头)的主要体尺指标,并进行134d的强度育肥试验。育肥结束后,选取12头江汉水牛(公牛6头、母牛6头)进行屠宰和肉质性能测定。【结果】江汉水牛育肥期平均日增质量为(818±189)g,平均日采食量为26.87kg。江汉水牛屠宰率为45.4%,净肉率37.6%,眼肌面积85.7cm²,肌肉嫩度平均为80.35kg/cm²,肌肉肉色评分7.83,滴水损失1.17%,江汉水牛产肉成本为27.57元/kg。[结论]江汉水牛躯体高大,骨骼粗壮,肉质优良,是培育乳肉兼用水牛新品种的良好遗传素材。关键词江汉水牛;体尺指标;生产性能;屠宰性能;肌肉嫩度;滴水损失ProductionperformanceandeconomicbenefitsofJianghanbuffaloHANAnqin,HUANGBin,HUANGXiangchun,LIBisheng,LIYouquan,WUWanhongHubeiProvincialLivestockBreedingFarm,Jingzhou434010,ChinaAbstract[Objectives]ThemainbodysizeindexesandproductionperformanceofJianghanbuf-falowerestudiedtoprovidethetheoreticalbasisfortheconservationandutilizationofJianghanbuf-falo.[Methods]Themainbodysizeindexesof20Jianghanbuffalo(10bullsand10cows)agedaround2.5yearsoldwithanaveragebodyweightof(360±59)kgweremeasured.A134-dayex-perimentofintensivefatteningwasconducted.12Jianghanbuffalo(6bullsand6cows)afterfatten-ingwereselectedtomeasuretheslaughteringperformanceandmeatqualityperformance.[Results]TheresultsshowedthattheaveragedailyweightgainofJianghanbuffaloduringtheperiodoffatteningwas(818±189)g,andtheaveragedailyfeedintakewas26.87kg.Theslaughteringrate,thenetmeatrate,theeyemusclearea,theaveragemeattenderness,themusclecolorscore,thedriploss,andthemeatproductioncostofJianghanbuffalowas45.4%,37.6%,85.7cm²,80.35kg/cm²,7.83,1.17%,and27.57yuan/kg,respectively.[Conclusions]Jianghanbuffalohasbigbodysize,strongbones,andexcellentmeatquality,makingitagoodgeneticmaterialforbreedingnewvarietiesofbuffalothatcanbeusedforbothdairyandbeef.收稿日期:2...
