BACKGROUND In 2010, foot-and-mouth disease (FMD) occurred for the first time in a decade in Japan. Movement or shipment of people and animals around infected farms was restricted; however these contingency measures proved insufficient to prevent FMD spread. Consequently, a total of 292 farms were confirmed as infected during this outbreak. We conducted a case-control study to identify the risk ...

This paper aims to analyse the technical efficiency (TE) of dairy farms and find its determinants. To accomplish this problem, Stochastic Frontier Analysis was applied. The data were obtained from Farm Accountancy Data Network database for (TF15-45—Specialist dairying) 2004–2019. Dairy divided into four clusters according their physical size (number livestock units per farm) economic (standard ...

The cost and return analysis of different sizes of broiler farms in the Punjab state has been carried out based on the primary data collected from 140 broiler farmers for the period March 2008 to February 2009 in three districts, viz. Ludhiana, Hoshiarpur and Muktsar. The study has shown that the total fixed investments per bird have been highest on small farms, followed by medium and large far...

Crop prices can affect farm productivity through input- output decisions. This study assesses the relationship between crop and changes among a sample of Kansas farms. The in total factor are evaluated using nonparametric approach with Malmquist index potential drivers technical efficiency change analyzed. Farms higher leverage greater diversification likely to be more efficient experience chan...

In 2003, a feed-borne outbreak of Salmonella Cubana occurred in Sweden as a result of contamination in a feed plant. Salmonella Cubana was detected in 49 out of 77 pig farms having received possibly contaminated feed. In this study, potential risk factors for farms being salmonella positive were examined, and a survival analysis was performed to investigate risk factors affecting the restrictio...

The well-known inverse relationship between farm size and productivity is usually explained in terms of diminishing returns with respect to land and other inputs coupled with various types of market frictions that prevent the efficient allocation of land across farms. We show that even in the absence of diminishing returns one can provide an alternative explanation for this phenomenon using end...

There are few published studies describing the unique management practices, farm design and housing characteristics of commercial meat chicken and layer farms in Australia. In particular, there has been a large expansion of free range poultry production in Australia in recent years, but limited information about this enterprise exists. This study aimed to describe features of Australian commerc...

A host of nutrients are needed by cattle to support functions associated with life, and to grow, reproduce, and nourish their offspring (i.e., produce milk). A vast amount of resources have been expended to quantify the amounts of specific nutrients needed to perform these function so that economically efficient diets can be formulated. Feeding diets that provide adequate, but not excessive, am...

We describe two parallel algorithms for line opacity calculations based on a local file and on a global file approach. The performance and scalability of both approaches is discussed for different test cases and very different parallel computing systems. The results show that a global file approach is more efficient on high-performance parallel supercomputers with dedicated parallel I/O subsyst...
