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...

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 ...

Campylobacter, mainly Campylobacter jejuni and C. coli, are worldwide recognized as a major cause of bacterial food-borne gastroenteritis (World Health Organization 2010). Epidemiological studies have shown handling or eating of poultry to be significant risk factors for human infections. Campylobacter contamination can occur at all stages of a poultry meat production cycle. In summer 1999, eve...

Two experiments were conducted to identify factors influencing feed conversion in broilers. The first experiment was conducted to develop a test for body temperature (BT) under mild handling stress. In the first experiment, BT was recorded periodically with birds briefly restrained after they had been removed from feed with either continuous lighting or 16L:8D. Body temperature was affected by ...

Collecting sera from new-born chicks requires their sacrifice, which is an invasive and little economic method of sampling. We studied the possibility of replacing the antibody titres in serum of chicks by those in pre-incubated egg yolk for determining the optimal Age of Vaccination (OAV) against Infectious Bursal Disease (IBD) by the Deventer formula. The study focused on 10 hyper-immunized b...

The study was carried out to assess the reproductive abilities of White Plymouth Rock (WPR) and Barred Plymouth Rock (BPR) parent stock (layer breeders) reared under similar housing (deep litter), management and agro-climatic conditions. A total of 1,763,322 and 1,732,966 fertilized eggs were produced by WPR and BPR, respectively, during the observed period which lasted four years (2002-2005). ...
