Data of four layers flocks (#31-34) from North Carolina Layer Performance and Management Test of the Department of Agriculture and Consumer Services were used in the meta-analysis to find if an increase in space allowance can affect egg production traits in white and brown layers. Effects of space allowance of 310 and 413 cm2/bird on layers performance were compared in this study. The increase ...

Red Junglefowl (Gallus gallus) is considered as the direct ancestor of domesticated chickens. There is a wide speculation on the on-going gene flow between Red Junglefowls in the wild and some neigbouring native chicken populations in South and Southeast Asia. This may challenge the reliability of specific morphological markers to differentiate them and may have implications on the utility valu...

Salmonella enteritidis lipopolysaccharide stimulates interleukin 10 (IL10) gene expression in chickens. Four genes in the IL10 cluster [polymeric immunoglobulin receptor (PIGR), interleukin 10 (IL10), map kinase-activated protein kinase 2 (MAPKAPK2), and ligatin (LGTN)] plus dual-specificity tyrosine-(Y)-phosphorylation regulated kinase1A (DYRK1A) were investigated using the F(8) generation of ...

in hot dip galvanizing, several parameters such as chemical composition of coating bath, immersion time and surface roughness of specimens could affect microstructure and properties of coating. in this article, the effect of aluminum content, immersion time and surface roughness on structure and properties of alloy layers have been investigated. specimens of low carbon silicon-free steel with d...
