Welfare problems, such as hunger, frustration, aggression, and abnormal sexual behavior, are commonly found in broiler breeder production. To prevent or reduce these welfare problems, it has been suggested to provide stimulating enriched environments. We review the effect of the different types of environmental enrichment for broiler breeders, which have been described in the scientific literat...

Paul Corral (American University) Most endogenous sample selection issues have been dealt with variants of Heckman's selection model. The model relies on the assumption of normality. However, when dealing with data where the data generating process is unknown, and the data may be less than ideal an information theoretic approach may be more suitable. During the summer I have been working on imp...

Data Farming is a process that has been developed to support decision-makers by answering questions that are not currently addressed. Data farming uses an inter-disciplinary approach that includes modeling and simulation, high performance computing, and statistical analysis to examine questions of interest with a large number of alternatives. Data farming allows for the examination of uncertain...

This paper conducts an empirical study on output, costs and incomes in organic farming with a sample of Spanish firms. Financial accounting data reveals that organic and partly or transitional to organic farming do not get significantly different output than intensive farming. Farms in transition to organic farming bear significantly higher costs and obtain significantly lower income than inten...

This pilot analysis was conducted with data from 52 conventional grow-out broiler flocks in a prospective field observational study in the southeastern United States during 2003-2006. Each flock was sampled for Salmonella 1 wk before the end of grow-out, upon arrival at the processing plant, and during processing (prior to and immediately after carcass chilling). The broiler litter was sampled ...

Broiler meat can become contaminated with Campylobacter of intestinal origin during processing. The present study aimed to identify the prevalence of Campylobacter in broiler flocks and meat contamination at retail shops, and determine the influence of semi-automated and wet market processing on Campylobacter contamination of neck skin samples. Samples were collected from semi-automated plants ...

An experimental study was carried over a period of 42 days using 160 day-old commercial broiler chicks (Ven Cobb) to study the effect of copper and flavomycin as feed additives on growth performance in broiler chicken. The birds were divided into four groups with four replicates of ten chicks in each replicate. The treatment (T1) was control with standard broiler ration and Cu as CuSO4 at 100 p...

One ecological environment monitoring system of Litopenaeus vannamei farming has been developed in order to protect and regulate the ecological environment of Litopenaeus vannamei farming, halt and reverses the situations in the ecological environment deterioration of Litopenaeus vannamei farming and the little farming success rate. The early warning information of ecological environment degrad...

While organic farming is well established in Europe a nd USA, it is still catching up in Asian countries. The government of South Korea has implemented environmentally friendly farming that encompasses organic farming. Despite the promotion of environmentally friendly farming, it still has a low share in South Korea and partially converted farming has emerged in some districts of South Korea. H...

This paper presents an approach to select the best farming strategy considering various criteria. The goal is to help a farmer to take appropriate decision in farming. Two possible alternatives are consideredConventional farming and Organic farming. These farming types are evaluated by MCDM technique taking into account three criteria viz. Productivity, Marketing, and Health-Environment Friendl...
