Maternal effects are important in epigenetic determination of offspring phenotypes during all life stages. In the chicken (Gallus gallus domesticus), transgenerational transfer of egg yolk factors may set the stage for morphological and physiological phenotypic differences observed among breeds. To investigate the effect of breed-specific yolk composition on embryonic broiler and layer chicken ...

As activity levels of intensively managed broiler chicken vary over time, detailed knowledge on their influence is potentially useful to further adjust welfare assessment schemes. Therefore, this study investigated the influence of daytime and age on the performance of broiler chicken in two applied fear tests. On-farm studies were carried out in 14 flocks of intensively managed broiler chicken...

this experiment was conducted to investigate the effects of lactobacillus acidophilus on performance, carcass characteristics, blood parameters, and intestinal microflora of broiler chicks. the dietary treatments were: basal diet as control 1; basal diet plus 1g. kg-1 of a commercial probiotic bioplus2; basal diet plus 10 and 20 g kg-1 fermented milk that contained 2×108 cfu g-1 lactobacillus a...

the aim of this study was to assess the effects of exogenous histamine and h1 and h2 central receptorson electrocardiographic (ecg) parameters, heart rate and mean electrical axis in broiler chickens. for thispurpose, ross broiler chickens (750-800 g weight) received intracerebroventricularly (icv) histamine.moreover, to determine the receptors involved in histamine-induced alterations in ecg c...

this study was conducted because of influence of prebiotics (alphamune) and symbiotic (biomin) on histometrical development of small intestine and lymphatic tissue of caecal tonsil have been not reported on broiler chicken. in this study, different parts of small intestine and caecal tonsil, which is a major area of gut associated lymphatic tissue (galt) in chicken were selected. one hundred an...
