家畜为人们提供肉食品的来源,家畜的质量与人们生活关系密切,肉食品不可或缺,因此对于家畜的质量有很高的要求。由于人们生活理念的变化,家畜品种改良成为一种社会发展的趋势。目前部分家畜品种存在一些问题,只能通过对家畜的品种进行改良解决存在的问题,给人们提供一个健康的食品环境。 相似文献

新疆托克逊县草地类型以山区荒漠类草地和盐化草甸土壤为主,草地资源利用低,草地资源开发受到诸多因素的制约,如畜牧企业少,资金短缺、土地使用受限制,产业化程度低,家畜饲草料短缺,季节性供草不平衡,草地沙化、退化严重。同时提出加强草地基本设施建设、实行计划放牧、合理利用草地资源、调整农业种植业和畜和群结构、加强草地监测和草原投入等草地资源可持续发展的对策。 相似文献

玛曲县草畜平衡优化方案与管理决策初探 总被引:1,自引:0,他引:1
利用玛曲县2001-2009年的草地畜牧业动态监测资料和社会经济统计数据,通过MATLAB 7.9软件的多目标规划方法,以维持草畜平衡、优化畜群结构和保护草地生态环境为总目标,综合考虑畜群结构优化、牧业生产、生态保护3个方面的约束条件,研究了规划期(2010-2012年)玛曲县草地畜牧业发展的优化方案及管理对策,对比分析了2套不同收入水平的优化方案。结果表明:减少家畜数量,加大周转是实现上述目标的根本途径,其具体措施包括调整牲畜数量和优化畜群结构。优化方案表明玛曲县若减少149.18×104 SU后,能实现草畜平衡;提高出栏率,增强畜牧业生产效益,从优化方案中发现出栏率保持在31%以上能够使牧民收益最大化;增加补饲,全县每年至少补饲精饲料4万kg;拓宽经济收益渠道,发展旅游等其他产业,将增强该县经济弹性。 相似文献

天祝县草地资源对白牦牛产业化发展的影响 总被引:1,自引:0,他引:1
天祝县是甘肃省重要的畜牧业基地,是白牦牛唯一产地。由于超载过牧,利用不合理,使得天然草原普遍退化,鼠虫害及毒草危害严重,可利用草地质量下降,面积缩小,不仅影响当地草地畜牧业生产,也制约了天祝白牦牛产业化发展。必须通过加强草原保护与建设、扩大人工草地种植面积、加强白牦牛保种选育、提高白牦牛改良选育水平等措施和手段,才能使天祝的畜牧业生产走向持续、稳定和良性循环的轨道,也才能使天祝的白牦牛生产真正走向产业化。 相似文献

在半农半牧地区,草原资源家庭责任承包制的实施使土地被过分细分到户,导致草地的破碎化。研究表明:强化草原管理有利于以草定畜,严格控制牲畜饲养量,草地超载及代牧现象减少;畜种改良使得传统的草原放牧向半放牧半舍饲过渡,大牲畜的饲养量出现大幅度减少;草地破碎化使得草地退化以定居点和水源为中心,沿着牧道呈一定的梯度形成辐射状的区域性草地退化趋势。通过草地的联户承包,共同经营管理,促进了草畜平衡制度的顺利实施,一定程度上解决了草畜矛盾,减缓了草原生态恶化的趋势。 相似文献

Equine extension programs, targeted at adult audiences, have been coordinated and delivered by the Extension Horse Specialist direct to horse owners with minimal support from county livestock agents. Increased agent responsibilities and limited training continues to limit livestock agent involvement. The Regional Equine Information Network System (REINS) was established in 1995 as a pilot program of the North Carolina Cooperative Extension Service. The program uses volunteers as trained paraprofessionals to assist in the development, management and evaluation of county and regional extension educational programs for recreational and professional horse owners.Through the guidance of a REINS coordinating extension agent, horse owners in a multi-county area were organized into a regional horse educational organization. The REINS organizations linked the educational efforts of the Cooperative Extension with the North Carolina Horse Council and Agri-businesses. Producers from each participating county within a region were identified to receive specialized training as a REINS volunteer. The Extension horse specialists and veterinarians provided volunteers with 38 hours of training on horse management and science topics, teaching techniques and program planning. Upon completion of the training, participants who successfully completed a certification exam served as unpaid Extension paraprofessionals.REINS volunteers assisted county Extension agents in the preparation of educational materials, formation of advisory groups, delivery of educational presentations, and the evaluation of the impact of REINS programs on horse owners. A pilot program, conducted in 1995–96 (Phase I), organized 31 counties into five REINS regions. Forty-two REINS volunteers received certification and reported an average of 404 hours donated per volunteer REINS region valued at $5,656 in volunteer time. An additional nine REINS regions including 69 counties will be organized and 72 volunteers certified in 1997 (Phase II). Phase III, offered in 1997–98 will provide specialized advanced level training. 相似文献

Indigenous rangeland management practices, forage quality and availability, and livestock production by pastoralists and agro-pastoralists in miombo woodlands were investigated in a study conducted in Kilosa district, Tanzania. The study methods comprised household interviews, key informant and focus group discussions, and forage laboratory analyses. Preferred forage species and indigenous rangeland and livestock management practices among pastoral and agro-pastoral communities in miombo woodlands were identified, and the nutrient content of the forages was determined. In general, rangeland management in the study area faces challenges such as unclear or disputed land tenure regime and lack of technical knowledge. Moreover, the nutritional value of some native forage species identified in miombo was found to be too low to meet the nutrient requirements of livestock. Livestock in miombo contribute greatly to household livelihoods and food security, but forage scarcity was identified as a limiting factor. Overall, it was concluded that rangeland improvement practices are poor or nonexistent in allocated grazing areas in Kilosa’s miombo woodlands. 相似文献
