The purpose of the present study is to get a better knowledge of the Malagasy indigenous race of hen through its egg physical characteristics and its laying performance in order to promote villager poultry production. This study was undertaken within a local family farm, of the rural Township of Ambalamahasoa, Haute Matsiatra Region, Madagascar, with 25 hens and 4 roosters in age to reproduce. ...

The objective of the following study was to determine the incidence of tibial dyschondroplasia (TD) among 4 crosses (crosses A, B, C, and D) of male meat-type commercial broilers and its relationship to gait score at 6 wk of age. At 38 and 39 d of age, 360 birds were evaluated individually for gait score. Three male chickens/pen with good walking ability (gait score of 0 or 1) and 3 male chicke...

Food safety and shelf-life are both important microbial concerns in relation to broiler meat production. Focus is mainly placed on the absence or control of potentially pathogenic microbes such as Salmonella spp. and Campylobacter spp. but, from the commercial point of view, other spoilage bacteria also play a role as potential threats. Regarding food safety, the primary target should be the pr...

Most published research concerning the environmental impacts of broiler poultry production is limited to assessments of on-farm gaseous and nutrient emissions. Here, ISO-compliant Life Cycle Assessment was used to predict the broader, macroscale environmental impacts of the material and energy inputs and emissions along the US broiler supply chain. It was found that feed provision accounts for ...

Poultry are commonly infected with a wide variety of salmonella serovars and infection is generally subclinical (Wray et al., 1996). Poultry farming is often hampered by reduction in productivity due to infections with large number of bacteria, salmonellosis being the most important causing great economic losses due to mortality and reduction in egg production (Khan et al., 1998). Under the new...

Chickens have been in Papua New Guinea since the time of the Austronesian settlements some 2000-3000 years ago. In historical times, new types of poultry were introduced. Chicken keeping slowly spread but only recently into the highlands. From the late 1960s through the 1980s, serious attempts were made to improve village poultry production through the distribution of dualpurpose chickens and M...

Aflatoxins (AF) are a major concern in poultry production and public health because of serious economic losses and health problems. AF contamination causes reduced feed quality and reduced animal efficiency either through poor conversion of nutrients or problems such as reproductive abnormalities. Aflatoxicosis in poultry also causes listlessness, anorexia with lowered growth rate, poor feed ut...

Effect of Poultry Litter Biochar on Saccharomyces cerevisiae Growth and Ethanol Production from Steam-exploded Poplar and Corn Stover

Every poultry farm has its own risk profile for the introduction of pathogens, subsequent development of disease, and spread of pathogens to other farms. This risk profile is determined by a complex interaction between the levels of infection in an area, the measures implemented on the farm to prevent disease, and other factors including the density of farms in the area and linkages with other ...
