In recent years, the traditionally pasture‐based dairy farms in New Zealand have become more intensive by using higher proportions of supplementary feed. This trend has been attributed to a range of factors, such as productivity enhancement, overcoming pasture deficits and the improvement of body condition scores. However, there is a lack of knowledge as to how feed use intensification affects the technical efficiency of dairy farms in New Zealand. This paper addresses the research gap by estimating the impact of feed use intensification on the technical efficiency of New Zealand dairy farms, using a fixed effects stochastic production frontier model and a balanced panel of 257 farms from 2010 to 2013. The empirical results show that technical efficiency on New Zealand dairy farms is positively and significantly influenced by feed use intensification, herd size and milking frequency. 相似文献

Abstract The economic downturn in Malaysia has encouraged a debate on the benefits of its export-oriented industrialisation strategy. There is renewed interest in the agricultural and livestock sectors. One of the beneficiaries of this policy change could be the dairy farming sector. Using desktop research and ‘key-informant’ techniques, this study reviews various factors that could influence the development of the dairy farming sector in Malaysia. The study concludes that the (a) Government may encourage the start-up of integrated plantation crop, animal feed and livestock farms, (b) investment and trade linkages with neighbouring countries could lead to diversification of import sources, and (c) consumption of dairy products may have matured, leading to increases in dairy self-sufficiency. It is postulated that these developments will produce a dynamic environment and significant threats to the interests of traditional dairy exporting countries. 相似文献

AbstractMastitis infections cause severe pain in dairy cows and are the most costly illness to farmers. This study combined differentiation and consolidation (Diff-Con) theory with risk-benefit analysis to explore how risky decisions are perceived and justified after a decision has been taken. More specifically, using survey data from 428 Swedish dairy farmers, their decisions about adopting preventive measures to control mastitis (mastitis control options, MCO) in dairy herds were examined. The analyses included group comparisons with non-parametric rank tests and use of both ordinary least squared regression and seemingly unrelated regression analysis to examine how prior adoption of MCO affects farmers’ attitudes to the MCO. The results showed that MCOs already adopted were rated higher in perceived riskiness (if not implemented) and in expected benefit (for illness prevention) than non-adopted MCOs. Having made the decision to implement a strategy increased the likelihood of that decision being perceived as more beneficial (reducing mastitis) and risky (in terms of disease increase if not implemented), irrespective of the combination of strategies used on the farm, during the post-consolidation stage. No difference in perceived illness prevalence could explain the farmers’ rating of the MCOs. These findings suggest that there may be a path dependency in farmers’ decision-making with respect to MCO. This implies that novel MCOs may have difficulty in achieving wider implementation. These results have implications for the development of strategies to communicate best practices for use of MCOs and for new research on MCOs and farmers’ decision-making. 相似文献

新疆与内蒙古、青海与西藏并称为中国四大牧区,拥有天山北坡、伊犁河谷、南疆绿洲等大畜牧基地,草场面积辽阔,达到5133万hm2,具有发展乳业得天独厚的优势。然而,具有如此优势的新疆乳业却很少能走出新疆,与内地特别是内蒙乳业发展差距很大,而且,新疆没有出现象"蒙牛"和"伊利"这样能享誉全国的乳品龙头企业,本文试图从供应链的视角看新疆乳制品企业的发展状况,希望把这种新型的结构介绍给企业。 相似文献

China's dairy industry has experienced rapid expansion in recent years, with an average annual growth rate of 23.8 percent from 2000 to 2006. However, there exists a serious geographical distribution imbalance in milk production and consumption. Approximately 85 percent of China's milk is produced in northern China, where 40 percent of the country's population reside. In contrast, only about 15 percent of the milk is produced in China's south, where 60percent of China's population reside. This has resulted in a significant gap between milk production and consumption in southern China and this gap is expected to rise. This paper considers China's milk demand and supply situation, analyzes the likely potential for China to expand its milk production and explores options for meeting milk demand-supply shortages. Policy and trade implications are discussed. 相似文献

The Demand for Hedging and the Value of Hedging Opportunities 总被引:1,自引:0,他引:1
Darren L. Frechette 《American journal of agricultural economics》2000,82(4):897-907
Hedging strategies typically assume that hedging is costless and that only one futures market exists. When these assumptions are dropped, the demand for hedging is shown to depend on basis risk, price risk, and the hedger's risk preference. The marginal and incremental value of hedging opportunities are computed for the general cases of one and two markets and applied to the specific case of Pennsylvania dairy input hedging. 相似文献

Ten dairy farms participated in an EU project that aimed to improve nitrogen use and assist with the adoption of more environmentally friendly farming practices. Nitrogen use and management decisions were monitored during 2003, 2004 and 2005. Nine farms improved nitrogen use (nitrogen output relative to input) in Year 2. Four farms maintained or further improved nitrogen use in Year 3. Management decisions and external factors that improved nitrogen use were increasing farm milk output, adopting best management practices for nitrogen use, growing forage crops that required less nitrogen than grass and favourable crop production conditions that rendered large quantities of good quality forage. Decisions that worsened nitrogen use were increasing cow numbers without sufficient management support, the late start of supplementary feeding when grass quality declined, setting the target yield too high, pursuing a higher milk price, less palatable silage and disease. Sufficient slurry storage is essential to improving nitrogen use. The savings from lower nitrogen input and the revenue from milk were in no proportion to the investments required for additional slurry storage, however. The farmers did adopt environmentally friendly practices, but only to the degree their businesses were able to sustain. 相似文献

This paper provides an analysis of 50 years of policy aimed at ensuring an adequate milk supply to Dar es Salaam, Tanzania. Despite a variety of policy approaches and initiatives, providing the city with milk continues to be problematic. The use of the peri-urban zone for dairy production is one of several recurring themes, however, even with an expanding market there has been relatively little development of commercial dairying in this zone. This history is used to assess the more recent interest in the potential contribution of the peri-urban zone to sustainable urban food supplies. The paper argues that policy and development initiatives along these lines must specifically consider the relative suitability of the peri-urban zone vis-à-vis the production of specific commodities as well as potential market opportunities. Those interested in promoting peri-urban agriculture as an element of more sustainable cities cannot afford to take a narrow view that ignores either agro-ecological, economic and regional realities. 相似文献
