内蒙古乌拉特中旗肉羊养殖成本效益调查报告 《畜牧与饲料科学》2016,37(3):79-79
肉羊业是改变内蒙古乌拉特中旗农牧业产业结构的重要推动力,是当地农牧民增加收入的重要途径。近年来,乌拉特中旗的肉羊业得到了快速的发展,肉羊养殖逐步走上了科学化、规模化、专业化、组织化生产的道路,也带动了地方经济的发展,提高了农牧民的收入水平。但是肉羊业在快速发展的同时也存在着很多问题,因此如何解决养殖中的问题,提高肉羊养殖的效益,促进肉羊业的发展对发展当地经济,增加农牧民收入有着重要的意义。对乌拉特中旗规模化舍饲肉羊养殖场(户)、农民小规模半舍饲肉羊养殖户、专业化羔羊育肥羊场(户)的成本效益进行了比较分析,找出了肉羊养殖中存在的问题,如饲料成本不断增长、周转资金缺乏、人工费用上涨等问题,提出了一些降低肉羊生产成本,提高养殖经济效益的建议及对策。 相似文献

近年羊肉市场日益火爆,肉价格显著增加,上涨到70元/kg。尤其是2018年下半年非洲猪瘟疫情爆发流行大背景下,生猪养殖产业面临巨大经济损失的同时,进一步推动肉羊养殖产业的发展。通过积极发展规模化肉羊养殖产业,能实现贫困地区群众的脱贫致富,更好地带动农村地区的经济发展。但养殖业发展期间,很多管理人员只看到经济效益,忽视对技术的学习,造成规模化肉羊养殖中存在很多问题,影响肉羊生产性能,甚至会加重疫情的发生流行,威胁羊群身体健康。 相似文献

Dorper sheep is native to South Africa, it is one of the world famous mutton sheep breeds, it is a good terminal male parent of mutton sheep hybrid production, after be introduced into China, it has been distributed in many provinces (municipality, municipalities directly under the central government), and has played an important role in promote the commercial mutton sheep production in China. In this paper, through introducing the rapid growth and development of Dorper sheep, good meat performance of germplasm characteristics, and by introducing Dorper sheep at different regions in China,the first filial generation of hybrid with local sheep varieties respectively compared with local sheep in growth and development, meat performance, we found that the first filial generation of Dorper sheep as male parent hybrid with local sheep all showed strong heterosis, and could be used as excellent male parent varieties of cultivate the new mutton sheep varieties and hybridization and improvement in China. 相似文献

Meat quality means the characteristics such as appearance is related to palatability in fresh meat or manufactured meat, it includes meat color, meat structure, hardness, marbling, water holding capacity and so on.The physical characteristics of mutton quality determines the consumer acceptability of meat and there is a close relationship between chemical composition of mutton quality and nutrient substance.With the improvement of living standards, consumers are increasingly high demand for mutton.From quantitative to qualitative change, we need to continuously improve mutton quality.At present, the production of high quality animal products has become a hot topic.This paper is a summary of the effects of breed, gender, age, environment and feed nutrition on mutton quality, and aims to provide a scientific basis for improving of mutton quality with nutritional regulation measures. 相似文献

江苏省肉羊产业发展现状、问题及对策 总被引:1,自引:0,他引:1
本研究运用2001—2016年统计数据,从肉羊存出栏量、羊肉产量、育种状况等方面分析江苏省肉羊产业发展状况,发现江苏省肉羊产业规模化不断提高,消费需求逐年增加,但2006年羊肉产量出现断崖式下跌,且近几年价格不稳定、肉羊种质资源质量下降,使得肉羊养殖收益不明显,肉羊产业竞争力减弱。江苏省肉羊产业发展存在标准化规模养殖水平不高、种质资源质量下降、信息不对称和品牌化程度不够等问题,并据此提出相关政策建议。 相似文献

We examined animal species differences in the postprandial thermic effect of meat and investigated the postprandial thermic effect of mutton in rats. After intake of experimental diets containing each meat, body temperatures of rats fed mutton or venison were significantly higher than that of rats fed rabbit meat. After intake of experimental diets containing fractionized mutton, the body temperatures of rats fed diets containing lean mutton protein were higher than those of rats fed diets without lean mutton protein. In a two‐dimensional fluorescence difference gel electrophoresis study of brown adipose tissue, it was shown that the intake of mutton up‐regulated the expression of many signaling molecules that are involved in energy metabolism. The postprandial thermic effect of mutton seems to be due not to catecholamine and adrenocorticotropic hormone but to thyroid hormones. The results suggest that intake of lean mutton protein stimulates the secretion of thyroid hormones and facilitates energy metabolism in rats. 相似文献
