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...

A lower price on poultry meat, compared with other meats (beef, pork etc.), affects the increasing demand for poultry meat. The productivity and production cost of broiler chickens are directly related to the amount of feed fed, the proportion of crude protein in the feed, and the biological value and price of the feed. The EU produces only 30% of the protein crops used for feed; thus, the larg...

Salmonella and Campylobacter cause foodborne enteritis mainly via the consumption of raw/undercooked contaminated poultry meat and products. Broiler flocks are primarily colonized with these bacteria; however, the underlying etiology remains unclear. The present study was conducted in order to obtain further information on the prevalence and genotypic distribution of Salmonella and Campylobacte...

A study with organic broilers with access to a large range area with herbs was performed and the effect of three broiler genotype (JA757, T851, SU51) with different growth rates and different feeding strategies (HP vs LP) on the animals' feed intake, growth and welfare was investigated. The results so far indicate that feed intake from range and animal welfare is dependent on type of allocated ...

OBJECTIVES This study investigated the occurrence of extended spectrum cephalosporinase (ESC)-producing Escherichia coli in a broiler production with no cephalosporin use and a low use of antimicrobials in general. Furthermore, it investigated whether the current consumption of aminopenicillins selects for ESC-producing E. coli and whether certain clones or plasmids spread from imported parent ...

In 2008 the Environmental Protection Agency (EPA) estimated that only 6.4% of U.S. greenhouse gas (GHG) emissions originated from agriculture. Of this amount, 53.5% comes from animal agriculture. Agricultural activities are the largest source of N2O emissions in the U.S. accounting for 69% of the total N2O emissions for 2009. In animal agriculture, the greatest contributor to methane emissions ...

The efficacy of bacitracin methylene disalicylate (BMD) in the management of necrotic enteritis (NE) when fed in combination with narasin was investigated in a floor-pen study of 2,000 broiler chickens using a Clostridium perfringens inoculum challenge model. Treatments consisted of 1) nonchallenged-nonmedicated; 2) challenged-nonmedicated; 3) challenged-narasin (70 ppm); 4) challenged-BMD (55 ...

Campylobacter was investigated in cecal droppings, feces, and cloacal swabs of 22 flocks of 3 to 5 week-old broilers. Risk factors and the likelihood of the presence of this agent in these flocks were determined. Management practices, such as cleaning and disinfection, feeding, drinkers, and litter treatments, were assessed. Results were evaluated using Odds Ratio (OR) test, and their significa...

This experiment was carried out to investigate effects of maternal ME and CP levels on growth performance, carcass traits, and meat quality of broiler offspring. A total of 1,134 thirty-week-old Chinese Yellow broiler breeders was randomly assigned to 3 dietary ME levels (11.09, 11.51, and 11.92 MJ/kg) and 3 CP levels (15.5, 16.5, and 17.5%) in a 3×3 factorial arrangement. Each dietary treatmen...
