  Yunling cattle is a three-way crossbred, of which the make-up of Yunling cattle is 1/2 Brahman, 1/4Murray Grey and 1/4 Yunnan Yellow cattle.Yunling cattle vary in color mainly from yellow, and black in hides with short and fine hair, intermediate in size, connecting well in all body parts, meticulous compact and more muscles, smaller head, bright eyes.Most of Yunling cattle are characterized with hornless, crosswise relaxing large ears, medium length of neck.Yunling bull have a larger hump over the shoulder, a developed dewlap under neck, chest and abdomen, wide and deep body, straight back waist, better formed hindquarter and hip.And,Yunling cow have a slightly hump, and a dewlap under neck.Yunling cattle possess slender tail, long limbs and strong hooves.The birth weights are 30.24±2.78 kg and 28.17±2.98 kg for male and female calves in Yunling cattle.The weaning and yearling weights are 182.5±18.8 kg and 176.8±17.6 kg, 284.4±33.7 kg and 281.0±34.1kg for male and female in Yunling cattle, respectively.The body height, body length are 148.92±4.25 cm and162.15±7.67 cm for adult Yunling bulls, 129.57±4.85 cm and 149.07±6.51 cm for Yunling cows, respectively.The body weights of Yunling bulls and cows reach 813.08±112.30 kg and 517.40±60.81 kg, respectively.In the process of top-grade beef production, the final weight reached 638.02±58.65 kg in the castrated Yunling bull at the age of 30 months, showing that dressing percentage was 65.81±6.05%, net meat percentage was41.07±2.40% (except for fat weight).And the loin eye area of 12-13th rib was 85.7±8.8 cm2, and the ratio of beef and bone was 4.71±0.59.The percentage of top-grade mass (fillet, high rib (chuck), rib eye and sirloin)accounted for 7.4% live weight.According to the standard of Japan, 70% animals reached Grade A3, with better taste and flavor, juiciness.Yunling cattle have the resistances to heat, tick and rough forage, and have some good performances involving in growth, precocious, reproduction, high-quality beef producing capability for snowflake beef and considerable benefit.Many farmers and farming enterprises are in great favor in Yunling cattle, promoting the stronger future for extension and application in the different climates in South China and Southeast Asia for grazing, "grazing + penned feeding" and "penned feeding".

为了解陕北地区黄牛的遗传多样性及遗传背景,本研究采用直接测序技术对55头饲养在陕北榆林地区的秦川牛及其多个杂交后代群体的线粒体DNA D-loop区826bp序列进行测定,结果表明榆林地区黄牛D-loop区序列A+T平均含量为61.5%,G+C含量为38.5%.共检测到33种单倍型和84个变异位点,核苷酸多样度(π)为0.02143,单倍型多样度(h)为0.970,表明陕北榆林地区的黄牛具有丰富的
本试验依据胴体重(hot slaughter carcass weight,HSCW)与肌间脂肪沉积的指数生长经验理论,以品种、年龄和肌间脂肪含量水平不同的牛为研究对象,建立以qPCR为基础的肉牛肌间脂肪含量预测模型.结果表明:IMF5中单个基因的表达水平与肌间脂肪含量的相关性不强.5个基因的表达量进行拟合后与肌间脂肪含量的相关性并未获得明显提升.但在排除两组离群动物的干扰后,IMF5与肌间脂肪含
为研究安格斯牛、黑毛和牛、南德温牛与秦川牛杂交改良效果.选择安格斯牛×秦川牛杂交一代(安秦F1)、和牛×秦川牛杂交一代(和秦F1)、南德温牛×秦川牛杂交一代(南秦F1)、秦川公牛各30头作为试验牛,分别测定初生重、不同月龄(6、12、18月龄)体重、体高、体斜长、胸围和管围等指标,并进行比较分析.在相同饲养条件下,6~18月龄的安秦F1、和秦F1和南秦F1的各项体尺指标均高于秦川牛,其中安格斯牛改
选取30头体况良好,体重相近(114.57±21.56kg),年龄为3周岁左右的环湖型公牦牛,采用单向分类试验设计,随机分为3个处理组进行舍饲饲养,每个处理组5个重复,每个重复2头牛.根据中国肉牛饲养标准(2004)中体重150kg、日增重500g的肉牛营养推荐值,配制综合净能(NEmf)分别为3.72 MJ/kg(82%,低能组)、4.52 MJ/kg(100%,中能组)、5.32 MJ/kg(
康奈尔净碳水化合物和蛋白质体系(CNCPS)是一种通过所建立的模型和饲料数据库对反刍动物饲料营养价值、生长生产性能、消化代谢情况等指标进行评定和预测的体系.CNCPS历经一系列更新,已发展至CNCPS6.5版本.本文阐述了CNCPS6.5对饲料蛋白质组分的重新划分和对氨基酸的组成和利用率的更新,并利用CNCPS6.5对前期文献报道的试验条件和结果进行评估.结果表明:CNCPS6.5预测ADG与实际
瘤胃调控微生态制剂具有调节动物体内微生态平衡,促进肠胃有益菌群生长,提高动物免疫力的作用.本试验主要探讨日粮添加不同微生态制剂对奶公牛生长性能的影响,为肉牛育肥绿色高效添加剂选择和应用提供依据.试验选取36头奶公牛,随机分为2组(Ⅰ组、Ⅱ组),Ⅰ组添加某益生菌,Ⅱ组添加某酵母培养物,试验期84天.结果表明:在84d试验期内,两组试验牛始重、末重均存在差异,但差异不显著(P>0.05);Ⅱ组试验牛采
本试验通过在相同饲养条件下,比较分析阉割奶公牛与和牛改良牛屠宰性能和肉品质,旨为利用奶公牛生产大理石花纹牛肉提供理论依据.选取自11月龄开始,在相同饲养环境和日粮水平条件下,强度育肥15个月的26月龄阉割奶公牛4头,阉割和牛改良牛5头,进行屠宰性能、肉品质对比分析.结果表明,屠宰率和肾周脂肪率两组差异不显著(P>0.05).分割部位肉中上脑、眼肉、后臀腿、肩肉占胴体比率的两组差异不显著(P>0.0
