南非肉牛考察报告(一)

<正>中国畜牧业协会牛业分会于2019年8月16—30日组织国内行业从业者赴南非考察肉牛,现将考察报告总结如下。1南非发展概况南非位于非洲大陆最南端,西面濒临大西洋,东面和南面濒临印度洋,自然环境优越,被誉为"彩虹之国"。南非地理位置独特,国土面积约为122万km~2,人口约     

中国畜牧业协会牛业分会赴四川省成都市调研牛肉市场和肉牛牦牛产业

<正>2019年4月16—18日,中国畜牧业协会牛业分会副秘书长赵航、会员部副主任李冬津赴成都市调研当地肉牛产业情况。重点了解成都及周边地区牛肉市场消费特点、肉牛养殖模式和经济效益状况等方面内容。调研结果显示,当前成都肉牛业从业结构相对简单,产业化程度较低,肉牛养殖主体为100头以内的小型规模养殖户,并通过经纪人将活牛及牛肉产品带入市场流通,形成产业链条。受商品牛源日趋紧张因素影响,成都及周边地区牛价近年来不断上涨,当前架子牛价格约28元/kg,育肥牛约     

解读当前牛源紧缺的根源及应对策略 “牛魔王”横行 专家纷纷出招降魔

<正>直击肉牛产业形势:肉牛价格上涨,牛源却遇瓶颈沈广(中国畜牧业协会牛业分会):2011年全国商品育肥牛平均价格约18～20元/千克,比去年增长20%;牛肉价格稳步攀升,最高同期涨幅达到4.68元/千克。可全国肉牛存栏总数持续下降。孙少华(河北农业大学动物科技学院):2010年肉牛存栏数和产肉量稳中有降,存栏6300万头,低于2009年,其中母牛不足3500万头;牛肉653.1万吨。由于基础母牛不足,进而造成牛源短缺,仍然是制约肉牛养殖业发展的关键环节。养殖成本高位运行,养殖效益略有增长,养殖仍以农户分散饲养基础母牛(10头以下规模的占60%以上)和异地集中短期育肥架子牛为主的基本态势。     

南非肉牛考察报告(二)

<正>(上接2019年11期《饲料与畜牧》第36页)4.2访问养牛农场,考察肉牛品种南非牲畜的良种主要来自两个方面:一是本地品种经过驯化改良而培育的品种;二是引进外来品种的基因资源,并与当地牛杂交繁育而形成的品种。南非肉牛良种的共同特点是受胎率高、繁殖率高、产犊率高、增重速度快、牛体格健壮、胴体品质好、耐热和耐旱、抗逆性良好、草食广泛。4.2.1访问西婆罗牛养殖场西婆罗牛(SimmentalBrahman)为西门塔尔牛和婆罗门牛的杂交品种,适合饲养     

平凉红牛杂交类群种质资源调查报告

平凉红牛是指在平凉特定的饲养传统、自然环境和气候条件下,以平凉当地黄牛为基础,先后引进秦川牛、利木辛牛、南德温牛等国内外优良品种,经过近五十年选育形成的体形较大、生长发育快、肉用性能优异、商品性状良好的红色肉牛杂交类群.其证明商标发布,标志着成功实现了由商品向品牌牛业的惊险跳跃,进入品牌发展时代.经过若干年育种措施,可望形成新的肉牛品种(品系).     

国际肉牛育种的新动向-小型肉牛培育

Heartworm in dogs in Canada in 1984

In late December 1984, 1853 institutional veterinarians and small and mixed animal clinics across Canada were sent a questionnaire in order to assess the status of Dirofilaria immitis in Canada in 1984 and 35% of them responded. Veterinarians reported that 97,794 dogs were blood-tested to check for microfilariae and 1417 dogs (1.45% of those tested) were found with heartworm. Another 34 dogs were amicrofilaremic, but were diagnosed as having heartworm disease, to give the total number diagnosed in 1984 as 1451 (1.48%). Heartworm was reported from all provinces except Prince Edward Island and Newfoundland but most (1310) of the cases were in Ontario. In Quebec, 126 cases were reported mostly from west of Montreal.

Heartworm was found most frequently in companion dogs over three years of age maintained mainly outdoors in rural areas. About 27% of the cases were observed with clinical signs of heartworm disease and 72% had a history of not having left Canada. Southwestern Ontario continued to be the primary focus of the infection.

Veterinarians reported that 59 504 dogs were blood-tested to check for microfilariae and 771 dogs (1.30% of those tested) were found with Dirofilaria immitis. Heartworm disease was diagnosed in all provinces except New Brunswick and Newfoundland but most (733) of the cases were in Ontario.

Heartworm disease was found most frequently in companion dogs over three years of age maintained mainly outdoors in rural areas. About 31% of the cases were observed with clinical signs of heartworm disease and 64% had a history of not having left Canada.
