leghorn

The effects of thiourea injection on scale development were studied in New Hampshire Red x White Leghorn Cross chick embryos. Normal morphogenesis and keratinization of scales were significantly delayed in thioureatreated specimens. Subsequent thyroxine injection resulted in normal or even precocious scale development. The thyroid hormone responsiveness of scale development is discussed in rela...

background: major histocompatibility complex (mhc) in chicken has profound influence on resistance/susceptibility to disease, and production and reproduction traits. microsatellite marker lei0258 is a genetic indicator for mhc haplotypes. recognizing diversity of mhc haplotypes in selectively bred populations will be helpful for selecting population resistant to disease and development of effec...
