自20世纪70年代以来,全球肉羊标准化迅速发展,尤其是发达国家肉羊标准化发展已经形成了较为完整的体系,其对促进发达国家的畜牧业发展、农牧民增收、农牧业贸易和推进农牧业现代化发展等都起到了十分重要的作用。我国肉羊标准化规模养殖比重低、标准化水平不高。因此,推进肉羊标准化规模养殖,以规模化带动标准化,以标准化提升规模化,逐步形成肉羊标准化规模养殖发展新格局具有重要意义。 相似文献

本文就中美贸易战对我国牛羊产业发展的影响展开了分析。分析认为:中美贸易战将促进我国牛羊产业结构性改革,倒逼产业转型升级,也将推进我国饲草产业优化调整,为饲草产业发展带来机遇;同时引致饲料饲草价格上涨,养殖成本增加,预期利润率下降,养殖规模增速受限;加之中美贸易战情况复杂,贸易风险不确定性加大。对此,从短期和长期2个层面提出应对策略:短期应增加能繁母畜和良种补贴力度,对苜蓿和大豆种植给予补贴;长期应建立中小养殖户和规模化肉牛肉羊养殖场并存的养殖结构,提高牛羊养殖业的服务能力,加强牛羊肉加工企业品牌建设和推进饲草饲料多元化。 相似文献

大通量的抗生素药敏检测盒的设计及应用 总被引:2,自引:0,他引:2
基于琼脂稀释法,设计制作了96点阵抗生素药敏检测盒。以NCCLS(2007)抗生素最低抑菌浓度(minimal inhibitory concentration,MIC)微量稀释法为对照,测定了分离自规模化猪场饲养员和幼儿园、中学学生的98株大肠杆菌对恩诺沙星、环丙沙星、诺氟沙星和中药三黄汤的药物敏感性。结果表明,两种方法测定的最低杀菌浓度(minimal bactericidal concentration,MBC)、MIC都表现高度对称,其差值的平均值都在一倍稀释度内,在差值0.5 μg/mL范围内都达到90%以上的符合。MBC与MIC高度相关,r=0.94~0.99。这些指标说明两种方法测定的MBC与MIC平行性好。以总体的抗生素敏感性频率比较,两种方法测定值也很相近,符合率为93.93%。本检测盒还可以准确测定中药三黄汤对大肠杆菌的MIC(125~500 mg/mL)。96点阵抗生素药敏检测盒是适合于实验室进行大规模抗药性监测的新工具,具有简易、准确、快速、大通量、节约的优点。配合96孔培养板,一次可以测定96株病原菌对一种抗生素或中药的敏感性。 相似文献

A seven point locomotion scoring scale, ranging from 0=normal locomotion to 6=unable to stand or move, has been developed. To test the between and within observer reliability of the scale, 65 movie clips of sheep with normal and varying degrees of abnormal locomotion were made. Three observers familiar with sheep locomotion were trained to read the movie clips. Thirty clips were randomly selected and used to test between and within observer agreement. There was high inter-(intra-class correlation coefficient [ICC]=0.93, weighted kappa [kappa(w)]=0.93) and intra-(ICC=0.90, kappa(w)=0.91) observer reliability, with no evidence of observer bias. The main between score differences were for scores 0 (normal) and 1 (uneven posture and shortened stride but no head movement). The results indicate that the locomotion scoring scale using groups of defined observations for each point on the scale was reliable and may be a useful research tool to identify and monitor locomotion in individual sheep when used by trained observers. 相似文献

Under the experimental conditions of a clinic, zeolite from the N. Hrabovec locality was studied as to its effect on the health condition of sheep. Zeolite was added to the feed mixture at a rate of 0.15 g per 1 kg of live weight daily for three months. The trials were performed with five sheep of the Merino breed. Five sheep were used as controls. No differences were found in the health condition and general behaviour of sheep fed zeolite and sheep of the control group. Neither were substantial differences observed in the indices of the other parameters under study--actual and total acidity, content of volatile fatty acids in rumen contents, blood picture, content of macroelements and microelements, nor in the transaminase activity of blood serum and acid-base homeostasis in blood. Before the zeolite supplementation of feed ration is introduced in practice, detailed studies should be conducted and the optimum zeolite dose should be determined. 相似文献

The avoidance of ammonia by sheep was tested using operant conditioning techniques, training 12 sheep to operate a lever to open a door that would allow them to traverse a chamber with or without ammonia and obtain a food reward. One half of the sheep had been previously exposed to ammonia at 45 ppm in a simulated ship voyage, and the other half were kept in identical conditions but without ammonia. The maximum number of lever presses, or breakpoint, achieved when the chamber contained 45-ppm ammonia was compared with the number when the chamber contained no ammonia. There was a significantly lower mean breakpoint when the sheep traversed the chamber filled with ammonia (mean: 4.2 presses), compared with the chamber filled with fresh air (mean: 6.6 presses), demonstrating that sheep exhibited a moderate aversion to 45-ppm ammonia. Although the scale of the reduction in mean breakpoint was considerable, the aversion was only clearly demonstrated in 75% of the sheep, and there was no evidence that prior exposure influenced this aversion. It is therefore concluded that sheep show a moderate aversion to 45-ppm ammonia, with no evidence of sensitivity being affected by previous exposures. 相似文献

2007年小反刍兽疫(PPR)在我国西藏首次暴发,在西藏和新疆部分地区使用PPR Nigeria 75/1疫苗株制造的疫苗进行免疫接种。为明确疫苗的安全性,中国兽医药品监察所国家牛瘟参考实验室对其安全性能进行了系统评价。健康易感山羊、绵羊及怀孕山羊、怀孕绵羊按不同剂量接种疫苗后,均未观察到异常临床反应;怀孕母羊所产羔羊数量与对照组无明显差异。疫苗对小白鼠、豚鼠的非特异性安全试验表明,所有接种动物均健活。结果表明该疫苗安全性良好,可在田间大规模使用。 相似文献
