The production system using cages is a highly polemical issue in Europe, because of the space restriction imposed to laying …
Developmental states are criticized for rapid ‘‘industrialization without enlightenment.’’ In the last 30 years, China’s breathtaking growth has been achieved at a high environmental and food safety cost. This article, utilizing a recent survey of China’s livestock industry, illustrates the initiating role of China’s developmental state in the exponential expansion of the country’s livestock production. …
The impact of animal welfare on the food chain is considerable. Firstly, an animal’s welfare, its health status, level of stress prior to slaughter etc. has a direct impact on the quality of the product from that animal. The second impact is via citizens, whose strong commitment to animal welfare has led to increasing EU …
Stress and diseases have the potential to influence the deposition of eggshell pigmentation during egg formation. Therefore, defining the shell color of eggs on a daily basis could be a representative method for monitoring stress or health status of a flock and maintaining good performance. A novel way of measuring eggshell color based on visible-near …
This study aimed at studying alternative methods to induce molting and to compare them with the conventional forced-molting method (fasting). In the experiment, 420 70-week-old layers were used. The total experimental period was 140 days. Molting was induced during the first 28 days, when birds were submitted to the experimental treatments, and bird performance and …
Survey of the prevalence of Salmonella species on commercial laying farms in the United Kingdom – Oct 2007.
1. Contaminated chicken meat remains an internationally important vehicle for human infection with Salmonella and Campylobacter spp. In addition, the last 20 years has seen an international pandemic of human salmonellosis caused by the contamination of eggs with Salmonella Enteritidis. 2. It has been a long held scientific view that Campylobacter spp. and most, if …
Commencing in 2007, a collaborative project to develop the ’’National Animal Welfare Standards for the Livestock Transport Industry’’ (the Standards) was completed and the documentation was integrated with the existing industry quality assurance (QA) program, TruckCare. The project was the fifth in a series of 6 projects commencing from 1998, to develop industry-wide animal welfare …
This study was a 3 × 8 factorial arrangement of 3 nutrient densities (low, medium, and high) and 8 commercial …
An adequate supply of all nutrients, including proteins, fats, carbohydrates, vitamins, minerals and water, has to be provided to support …
The present study was conducted to determine the adverse effects of high temperature and humidity not only on live performance …
1. The applicability of different ratios of bitter vetch seed as a new method for moult induction in laying hens …
A study was conducted to evaluate skeletal quality and eggshell parameters of molted hens at the end of the second …
We experimented to evaluate the effect of a number of molting techniques that appeared to be less stressful than the conventional feed withdrawal (FW) method on postmolt performance. The molting techniques involved a continuous FW (T1, control group), 1 d FW followed by feeding a grape pomace (GP) diet containing 10 ppm thyroxine (T2) ad …
This experiment was conducted to determine the effects of cage location and tier level with respect to light intensity on …
During the past decade research work has indicated that ahemeral cycles could markedly influence egg production, shell quality and egg …
The chicken eye can discriminate light color, and different light wavelengths affect egg quality. In this study, we used blue …
