正奶山羊是人类驯化的最早奶畜品种之一。与奶牛相比,奶山羊个体较少,需要的草料投入较少,同时耗水量和污水产量均较低,因此一直受到个体养殖户的青睐。但也存在一些弊端:养殖方式过于粗放,大多饲养于开放式或半开放式的棚舍,奶山羊的健康和奶产品的品质得不到保障。近年来,一些规模化养殖户将漏缝地板模式引入奶山羊的养殖,羊粪尿通过漏缝地板进入漏缝地板下的粪坑,等到羊粪、尿积满粪坑时再一次性清出羊舍。漏缝 相似文献

[目的] 随着奶山羊养殖行业的发展,规模化、集约化程度不断提高,如何能更便捷地对奶山羊的健康状况和生产性能进行有效评判,是提高奶山羊养殖效率的重要措施。[方法] 本试验通过测定奶山羊体内外温度、产奶量以及乳成分,分析乳房温度与体内外温度以及与泌乳性能之间的相关性。[结果] 发现乳房温度与舍温、额温有明显的相关性（P<0.01）,但与眼温和肛温之间没有显著相关性;此外,乳脂、非乳脂固形物与乳房温度之间也存在显著的相关性（P<0.01）。[结论] 乳房温度是一个很好的评价指标,可适宜地用于监测奶山羊健康状况和生产性能。 相似文献

Production objectives and breeding practices of smallholder households participating in dairy goat breeding projects were
analysed in relation to their ability to bring about sustainable genetic improvement in the dairy goat flocks in Kenya. A
stratified survey involving 311 goat keepers in 4 project sites was used. This employed both qualitative and quantitative
research methods to get a holistic view of dairy goats, and take into account the full array of contributions of dairy goats
to the smallholder households. Milk production and sales of breeding stock were high priority functions for the objective
to create a financial buffer. The breeding objective traits that farmers perceived as being of primary importance were milk
yield, growth rate, body size, fertility and disease tolerance. There were logical trade-offs in the choice of these traits
by farmers. Female dairy goats were mainly culled due to old age, poor fertility, small body size and poor health. Farmers
did not place a large significance on unsatisfactory milk performance when culling female goats, mainly due to the very small
production size and the high demand existing for breeding animals. Factors affecting milk yield and flock size presented satisfied
a P < 0.1 significance level. The performance levels of dairy goats were mainly influenced by breeding strategies and the resource
availability at the farm level. The optimisation of genotype x environment interactions remains the biggest challenge given
the objectives set by the farmer. 相似文献

近年来,世界山羊养殖数量持续增长,据联合国粮农组织(FAO)统计显示,2018年全球山羊养殖数量已超10.4亿只,其中奶山羊养殖数量超2.16亿只,约有90%以上的奶山羊和山羊奶产自亚洲和非洲。欧洲的奶山羊存栏和产奶量均在亚洲和非洲之后,但其单产水平远高于其他各大洲,在世界奶山羊每只平均年产奶量100 kg以上的国家中,前十位均为欧洲国家。我国奶山羊产业发展迅速,2018年我国奶山羊实际存栏约518万只,年产羊奶量约100万t,约占全国鲜奶产量的3.3%。本文对全球及我国奶山羊产业进行了纵向和横向比较,客观分析我国奶山羊产业的地位、发展现状以及未来发展趋势,旨在为我国奶山羊产业的发展提供参考。 相似文献

近几年,陕西省宝鸡市千阳县围绕“追赶超越,打造中国奶山羊良种名城”、争创全省千亿级奶山羊全产业链龙头县、加快畜牧业转型升级的目标,大力发展奶山羊产业。随着养殖存栏的增加,市场流动频繁,疫病风险也相对增加,尤其在冬春季节产羔时期,正是养殖场疫病防控的空档期,疫病防控风险较大。本文在奶山羊产羔季节通过走访本县规模奶山羊养殖场,调查了解奶山羊生产中疫病防控的现状,综合研判当前疫情发展形势,提出加强该阶段奶山羊养殖场疫病综合防控措施,以期提高羔羊成活率,增加养殖场经济效益。 相似文献

With the development of intensive broiler raising, the influence of environmental factors on broiler health are increasingly prominent. Relative humidity is one of the most important indicators of broiler house environment.But in the production process of broiler farming,it is often neglected on the management of humidity in house. Neither low humidity nor high humidity is conducive to the healthy growth of broilers. It is of great significance to strengthen the monitoring of the humidity in broiler houses and study the effects of relative humidity on the health of broiler for guiding the rational control of the humidity in broiler houses and the development of healthy breeding. In this paper, we summarized and analyzed the effects of relative humidity on thermal regulating,growth performance, reproductive performance, blood parameters, meat quality and respiratory tract of broilers, and the monitor and control measures of humidity in the poultry house, aimed to provide a reference for further research on the mechanism of relative humidity affects broiler health and rational regulation of humidity in broiler house. 相似文献

随着肉鸡养殖集约化的发展,环境对肉鸡健康的影响越来越突出。湿度是肉鸡舍环境的重要指标之一,然而在肉鸡饲养生产过程中常常忽略对湿度的管理。低湿或高湿都不利于肉鸡的健康生长。加强对肉鸡舍湿度的监测及研究湿度对肉鸡健康的影响对指导鸡舍湿度的合理调控和健康养殖的发展具有重要意义。作者通过总结和分析舍内湿度对肉鸡热调节、生长性能、繁殖性能、血液指标、肉品质及呼吸道等方面的影响及舍内湿度的监测和管理方法,为深入研究湿度对肉鸡健康影响的作用机制及合理调控肉鸡舍湿度提供参考。 相似文献

Reproductive seasonality observed in all breeds of goats originating from temperate latitudes and in some breeds from subtropical latitudes can now be controlled by artificial changes in photoperiod. Short days stimulate sexual activity, while long days inhibit it. This knowledge has allowed the development of photoperiodic treatments to control sexual activity in goats, for both the buck and doe. In the French intensive milk production system, goat AI plays an important role to control reproduction and, in conjunction with progeny testing, to improve milk production. Most dairy goats are inseminated out of the breeding season with deep frozen semen, after induction of oestrus and ovulation by hormonal treatments. This protocol provides a kidding rate of approximately 65%. New breeding strategies have been developed, based on the buck effect associated with AI, to reduce the use of hormones. With the development of insemination with frozen semen, a classical selection programme was set up, including planned mating, progeny testing and the diffusion of proved sires by inseminations in herds. Functional traits have become important for efficient breeding schemes in the dairy goat industries. Based on knowledge gained over the past decade, the emphasis in selective breeding has been placed on functional traits related to udder morphology and health. New windows have been opened based on new molecular tools, allowing the detection and mapping of genes of economic importance. 相似文献
