人造肉的话题近半年火了一阵。资本市场的反应让人们难以不对它做点深入的讨论。即使人造肉有良好的前景,那也是很多年以后的事情了。今天,至于很久的未来,养殖肉还是肉类的主流。 相似文献

1“人造肉”研究的必要性
人造肉是一种未雨绸缪的研究，因为随着人口不断增加，到2050年全球人口可能达到90亿，肉食消费需求量将会翻倍。而未来的养殖规模显然无法满足所有人都要吃肉的要求。因此，未来需要修建一些人造肉工厂来满足人们的需求，这些人造肉并非是用植物蛋白或者动物油脂合成的，而是实实在在“生长”出来的肉块。 相似文献

<正>经合组织（OECD）和联合国粮农组织（FAO）预计,未来10年全球猪肉产量将继续稳定增长,但其增长水平却远无法达到禽肉增长的水平。除欧洲以外所有大洲的猪肉产量均增加;亚洲仍将是全球猪肉生产的主力;亚洲和北美洲猪肉产量增加最多;非洲、拉丁美洲和大洋洲猪肉增产量较少;欧洲猪肉产业虽在萎缩,但仍是全球猪肉生产中仅次于亚洲的第2个核心地区;发展中国家猪肉产量份额将继续上升;人造肉在肉类总消费中占比虽将有所增加,但也不大可能对肉类市场造成较大冲击。 相似文献

社会经济的快速发展，提高了人们的生活水平，使得人们对肉类食品的需求不断增加，在一定程度上促进了养殖业集约化、规模化的发展。高密度、大规模的养殖导生猪皮炎病的发病率逐年升高，给养殖户带来严重经济损失的同时，对我国肉类食品安全也造成了严重影响。 相似文献

从我国居民肉类与粮食产量和消耗量分析农业结构调整的必要性 总被引：2，自引：0，他引：2
我国经济的发展促使居民膳食结构升级换代成为一种不可逆转的趋势。本研究试图从农业系统食物产出中的肉食和粮食产出分析我国现行农业系统的结构性问题与缺陷。采用H-P滤波分析,通过对我国耗粮型和非耗粮型肉类产量以及粮食的稳定性与发展趋势进行研究发现:1)1992-2012年间,我国人均粮食消耗量、人均耗粮型肉类消耗量和人均非耗粮型肉类消耗量之比由1992年的70.53∶6.36∶1变化为2012年的9.37∶2.68∶1,人均粮食消耗量在人们膳食结构中显著降低,肉类消耗逐步上升;2)目前我国肉类产量处于波动上升阶段,随着肉类产量和消耗量大幅增加,继而使得粮食消耗增加;3)粮食产量稳步增长,但自2000年以后,我国粮食增产的潜力在逐渐减小。因此,在我国居民膳食结构调整的现实需求下,肉类需求的上升和粮食增长潜力减小的矛盾逐渐凸显,这使得降低动物粮食需求成为必要,增加食草性的非耗粮型肉类的产出,发展草地农业成为了可选的途径。 相似文献

近年来,随着人民生活水平的不断提高,商品流通渠道的不断扩大与完善,人们对肉类产品的品质及分类需求也越来越高,很多肉类生产加工企业抓住了商机形成了新的经营模式,致使各地市场出现大批＂外埠肉＂跨区域进入销售的现象,这给人民群众带来方便的同时,也给动物卫生监督管理工作带来了新的课题，提出了新的要求。 相似文献

At present, human's demand for meat is increasing, but the environment pressure caused by the meat production of livestock is also increasingly apparent. The development of green and sustainable meat substitutes to reduce global carbon emissions and meet the increasing demand for meat has become the hotspot of social concerns. Although artificial meat belongs to food, it still lacks in-depth analysis on whether it brings challenges or opportunities to the livestock industry. In this paper, the classification and development history of artificial meat, the existing core manufacturing technology and market prospect of artificial meat are summarized, and the importance of using the diversity of livestock and poultry germplasm resources to promote cell-based meat are analyzed. 相似文献

Demand is not measured by per capita consumption. Demand is a schedule of the quantities consumers will take at alternative prices. The level of demand and demand changes over time are tied to consumer incomes, prices of substitutes, and consumer tastes and preferences. Critical to increasing meat demand is a greater understanding of consumer preferences for new meat products. Developing branded products such as "natural" or "guaranteed-tender" beef may not be the answer for all cattle producers, but research suggests that there are segments of the population willing to pay premiums for such products. Differentiating meat products through technology and branding provides a means of better meeting consumers' desires and increasing overall demand for meat and livestock. 相似文献

粮草兼顾型畜牧业饲草料发展现状及展望 总被引：1，自引：0，他引：1
随着我国人口数量的持续增长,居民生活水平不断提高,粮食需求随之剧增,肉、蛋、奶等畜禽产品的消费也不断增长,人们对畜产品的需求决定着农业发展的方向。本文介绍了我国粮草兼顾型畜牧业发展的主要背景,简述了传统畜牧业和粮草兼顾型畜牧业对饲草料需求的异同,并分析了新形势下我国畜牧业发展的方向:1)针对我国居民膳食结构改变对农业结构发展模式的影响,提出现阶段发展草地农业,进行广泛的系统耦合是促进农业可持续发展的技术保障,是我国农业结构调整的必然之路;2)结合我国现阶段畜牧业发展现状,指出将牧草或其他饲料作物的生产利用纳入到农业生产体系当中,通过粮―草―畜有机结合,建立起土地―植物―动物产品完整的产业链条来满足消费者食物需求;3)建议通过增加优质牧草日粮比例、发展草食家畜、建设信息自动化等具体措施,来促进、引领和保证粮草兼顾型畜牧业的可持续发展。 相似文献

Status and prospects for livestock production in the Lao People’s Democratic Republic 总被引：1，自引：1，他引：0
Wilson RT 《Tropical animal health and production》2007,39(6):443-452
Some 16 per cent of the Gross Domestic Product of the Lao PDR arises from the livestock sector. Almost all output - live animals
and products - is from traditional small scale production and about 90 per cent of all households in the country keep one
or more species of livestock. Industrial or large scale production is of very minor importance even for pigs and poultry.
Considerable international assistance has been provided for livestock development, initially from the Socialist states that
were of the same political persuasion as Lao PDR and more recently from multilateral and bilateral development assistance
agencies. In general this assistance has not conferred lasting benefits on the sector in part due to the failure of the Lao
Government to provide continuing support commensurate with the sector’s contribution to the national economy. Buffalo (1.1
million head in 2004) and cattle (1.3 million head) are the main ruminant species with goats and sheep (140 000 head) occupying
a very minor position. Both pigs (1.7 million) and poultry (19.6 million) are major contributors to the household and national
economies. Buffalo are now mainly meat producers, their former draught and transport roles having been taken over by mechanical
equipment. Cattle, also once used for draught, are almost exclusively producers of beef. Pigs and poultry produce meat and
poultry provide eggs. Lao indigenous livestock are mainly kept in low input systems, thus output is also low. Nothing is known
of the genetic potential of the indigenous stock which are the victims of poor management, inadequate nutrition and minimal
health care. There is strong and rising demand for products of animal origin within the country and in the greater Southeast
Asia and East Asia regions. Given suitable and appropriate support the Lao livestock sector would be in a strong position
to contribute to supplying this demand. 相似文献

骨骼肌是生物机体的重要组成部分，约占产肉动物机体的40%，与畜禽的运动、发育及产肉能力等重要性状密切相关。骨骼肌是由平行排列的肌原纤维组成的多核肌纤维，肌纤维的数量、类型以及转变方式直接反映了个体肌肉发育情况以及机体的生理状况，因而在选育工作中作为重要的经济性状而被关注。对肌纤维的深入研究将有助于加快今后的选育进程，促进对近年频发的畜禽肌源性疾病的溯源与研究，从而缓解肌源性疾病对畜禽养殖业造成的经济损失，满足消费者对优质肉产品的需求。近年来，对肌纤维的认识与研究均取得重大进展，包括依照肌纤维的结构与功能特性对骨骼肌的生物学功能进行预测与验证、肌纤维的类型与肉品质的关联分析以及模式动物的应用，挖掘出肌纤维发生发育以及再生修复过程中的重要调控分子，并对它们的功能进行注释。作者参照现有研究成果对肌纤维的结构与功能进行系统的描述，并从分子层面对肌纤维胚胎期的发生发育以及出生后的再生修复进行综述，以期为今后提高肉用动物的产肉性能及培育高品质产肉动物新品种或新品系的选育工作提供理论参考。 相似文献

Much of the world's rangeland is dominated by woody species. Competing land uses and continued encroachment of woody species into non–woody-dominated rangelands have reduced grasslands in many parts of the world. Land use conversions to fuel and feed global populations, especially the increasing number of middle class people seeking broader, meat-based diets, will certainly continue. Halting and/or reversing further encroachment of woody species into grasslands is slow, expensive, and in some cases not possible. Yet, global livestock numbers continue to increase to meet the growing demand for red meat and other livestock products. How do we reconcile a world with less grass and the concurrent increased demand for forages to feed livestock? Strategies and mechanisms are needed to safely enhance shrub use by ruminants in order to capitalize on a presently underutilized forage resource. A number of approaches are presently available (e.g., choosing appropriate species and breeds, providing dietary supplements and additives, behavior modification, genetic selection) to increase shrub consumption, and new technologies such as biochemical markers of shrub intake need to continue to be identified and developed. Such strategies could provide important means for rural communities to adapt to changing land cover and climate. 相似文献

甜高粱作为优质饲草在我国草牧业发展中的潜力分析 总被引：3，自引：0，他引：3
随着我国节粮型畜牧业结构调整和不断发展,以粮换畜逐渐转变成以草换畜,因此对优质粗饲料的需求日渐增加。甜高粱作为一种新兴的高能非粮作物,因其生物产量高、营养丰富、光合效率高、抗逆能力强等特性,成为我国干旱、半干旱和高盐碱地区畜牧业的优质饲草来源。动物养殖中使用甜高粱,不仅可以缓解畜多草少的压力,还可以充分利用盐碱地和其他滩涂地,增加一定的经济效益。针对甜高粱作为优质饲草在我国草牧业发展中的潜力进行了综述,系统地阐述了其利用概况、利用技术开发进展、未来的发展方向,为甜高粱作为优质饲草在我国的利用和发展提供参考。 相似文献
