Indigenous chickens (IC) are mainly raised by resource poor rural households in developing countries [1]. Although they are of low genetic potential compared to the commercial breeds, IC play a vital role in livelihoods of farmers and contribute significantly to food security and income [1]. IC dominates in most smallholder farms in Malawi and they are deemed less productive but appear to be ad...

The genetic diversity of Campylobacter jejuni and Campylobacter coliisolates from commercial broiler farms was examined by multilocus sequence typing (MLST), with an assessment of the impact of the sample type and laboratory method on the genotypes of Campylobacter isolated. A total of 645C. jejuniand 106C. coli isolates were obtained from 32 flocks and 17 farms, with 47 sequence types (STs) id...

This study was conducted in order to investigate whether the presence of light or different colors of light would influence the energy expenditure and behavior of broiler chickens. Eight 8-week-old broiler chickens were adapted to a respiration chamber (Length, 28.5 cm; Height, 38.5 cm; Width, 44.0 cm) for one week prior to the initiation of the experiment. In experiment 1, energy expenditure a...

The present study was conducted to investigate whether dietary sanguinarine (Sangrovit ® , SGV) could affect growth performance, relative organ weigths, gut microbiota, serum cholesterol levels, and malondialdehyde contents of leg meat in broiler chickens. A total of 840 day-old male broiler chicks (Ross breed) was randomly placed on 28 floor pens with rice straw as a bedding and subjected to o...

Avian influenza is an important disease of poultry with the potential to cause major epidemics resulting in significant economic losses. The presence of avian influenza viruses (AIV) in chickens in Iran has not been previously reported. An avian influenza outbreak in broiler, layer and breeder farms occurred during a very hot summer in July 1998. Three AIV isolates designated as 101, 102 and 10...

Ornithobacteriosis is an infectious disease of avian species that has been reported in almost all countries around the world, except Thailand. The objectives of this study were to determine the seroprevalence of Ornithobacterium rhinotracheale (ORT) and to isolate and identify ORT in broilers and broiler breeders in Thailand. Chicken antibodies had been randomly checked from 17 farms (19 flocks...

Broiler chickens in Brazil are generally reared from 1 to 42 days when they are exposed to procedures such as fasting, harvesting, crating and transport to slaughter. Maintaining homeostasis is of great importance for broiler survival under harsh environment especially prior to slaughter. Heat loss varies in the distinct parts of the body during the growth period, and it is related to the air t...

The objective of our study was to test amaranth grain or dried biomass in the diet for broiler chickens as a resource of protein replacing animal protein. Further, the effect of amaranth on broiler performance, carcass characteristics and meat quality were assessed in a feeding trial. The experimental groups of broilers were fed feed mixtures with crude amaranth grain (AC), heat processed amara...

Blahová J., R. Dobšíková, E. Straková, P. Suchý: Effect of Low Environmental Temperature on Performance and Blood System in Broiler Chickens (Gallus domesticus). Acta Vet. Brno 2007, 76: S17-S23. The aim of this study was to assess the effect of low environmental temperature on growth, feed conversion, performance and selected biochemical and haematological indicators in broiler chickens. The d...
