2014年岁末,可谓是奶业的寒冬。昔日摇钱树如今成了累赘,显然让奶农们措手不及。国内多地奶价暴跌,山东、河北等地原料奶价格普遍下降,因为牛奶价低,无人收购等原因,奶农自2015年元旦起每天都要倒上千斤新鲜牛奶,部分奶农甚至开始卖牛。青海大通、湟中等奶牛养殖主产区也曾出现"倒奶"现象。分析人士认为,奶农倒奶的根本原因在于2014年进口奶粉价格暴跌。奶企囤积了过多进口奶粉,自然会逐渐减少鲜奶的收购。也有分析称,奶农在2013年原奶价格上涨的背景下加大奶牛饲养规模最终导致牛奶供过于求。 相似文献

奶牛跛行是奶牛发生肢蹄病的外在表现。人工识别跛行奶牛存在效率低、成本高、主观性强等问题。奶业对奶牛跛行自动识别技术需求日益强烈。本文从机器视觉技术、压力分布测量技术、可穿戴技术、行为分析技术和跛行分类技术5个方面,分析了奶牛跛行自动识别技术的原理、功能、特点及研究现状。总结发现,当前奶牛跛行自动识别技术研究大多集中在传感器研发和算法开发,而性能验证和决策支持的研究较少,面临的主要挑战包括高质量跛行识别数据获取难度大,缺乏早期跛行识别技术手段,奶牛个体差异干扰模型识别精度,牧场非结构化环境对识别系统性能要求高,以及技术应用效果难评估等。因此,为促进奶牛跛行自动识别技术的发展,建议推动牧场跛行监测数据共享,研究奶牛个体跛行判别模型的构建方法,开发融合跛行检测、体况评分等多功能的一体化智能通道,并分析评价跛行自动识别技术应用在保障动物福利、环境生态、粮食安全等方面的重要意义。 相似文献

区块链技术由于其分布式存储、交易信息透明、可追溯性强等特点,同中国农产品交易体系具有很好的互补性和适用性,应用前景广阔。然而中国的农产品交易体系又具有产品多样性,交易流程复杂性,用户群体的广泛性、分散性,隐私保护性等特点,为区块链技术在中国的农产品交易信息体系中的应用造成了很多现实困难。针对以上问题,本研究采用联盟链的设计思想,提出了包括农产品交易信息链、用户信息链、农产品信息链的多链式农产品交易信息区块链应用技术。农产品信息链提供农产品的详细信息,并保证信息的可追溯性和不可篡改性。在用户信息链中引入区块链节点准入机制,为农产品交易平台提供实名制凭证登记与管理功能。交易信息链记录所有交易智能合约的处理结果,通过加入通道技术,实现不同交易信息的相互隔离,可满足交易信息和用户数据的隐私保护和交易数据的快速处理。通过智能合约对交易利润进行自动分成,提高执行效率,降低交易成本。最终建立透明、高效、适用性强的农产品交易区块链架构。 相似文献

Interest in local food security has increased in the last decade, stemming from concerns surrounding environmental sustainability, small scale agriculture, and community food security. Promotions for consumption of locally produced foods have come from activists, non-governmental organizations, as well as some academic and government research and policy makers. Methods to empirically assess the types and quantities of crops and animals produced locally (i.e., local food production capacity) are under-developed, hindering the ability of policy makers to effect innovative local food security policy. In this paper, we demonstrate methods to estimate local food production capacity using regularly gathered federal Agricultural Census and survey data for a Canadian province. The methods are generalizable to other provinces and nations. Operating at the sub-provincial scale of Local Health Area (LHA), our goal is to integrate census farmland and survey yield data to construct local food production estimates in each LHA. We also assess the stability of these surveyed agricultural yields over time to determine the temporal extent of data required for reasonable representation of product yields. We find that provincial yield data may be used to construct reasonable estimates of local scale food production, due to the high level of regionalization in productive farmland of each product in the province. However, many products exhibit significant yield variability over time, suggesting that, for some foods, local production capacity is a dynamic and variable concept. The methods developed will be useful for researchers and government officials alike, as well as a first step towards more advanced modeling of current local food capacity and future potential. 相似文献

Milk composition varies between herds and cows within herds, enabling its segregation on farm, rather than during processing, for the manufacture of specific dairy products. Benefits may include increased product yields, reduced processing costs and greater suitability of differentiated milk for the production of high value niche market products. However, costs are also likely to be greater. An integrated spreadsheet model was developed to determine the break-even premium required for a farmer with a seasonal calving herd to be economically no worse off producing segregated than conventional milk. The model incorporated breeding (quantitative and qualitative traits), cow requirements and feeding, transport, and economic sub-models. Cows were segregated within herd and milk composition was altered over time by genetic selection. Four quantitative trait (“white” milk colour) scenarios and two qualitative trait (BB β-lactoglobulin milk) scenarios were considered.The model suggested that “white” milkfat would need to earn 38.4% more at the farm gate than conventional milkfat for the two systems to break even. “White” milk cows produced less than their status quo counterparts due to the reduced selection pressure on production milk traits and this had a considerable impact on the premium, as did the low initial volumes of white milkfat. The difference in production between the B β-lactoglobulin cows and their status quo counterparts was less than for selection on white milkfat only. The high risk to farmers of discontinuing a differentiated milk policy could be moderated by changing the structure of premium payments over time. Hence, processing companies and farmers will need to work together to facilitate the uptake of milk segregation. This research model could be applied by dairy companies and farmers considering milk segregation policies. 相似文献
