    DNA POLYMORPHISM AT MHC LOCUS AND ITS ASSOCIATION WITH DISEASE RESISTANCE AND ECONOMIC TRAITS IN INDIGENOUS CHICKEN
    (Birsa Agricultural University, Kanke, Ranchi, Jharkhand, 2007) Singh, Geeta; Singh, S.K.
    The Major Histocompatibility complex (MHC) is a chromosomal region containing a family of genes that encode a group of glycoproteins involved in regulating a number of cellular processes of importance to the immune response and it has been associated with growth and reproductive traits in a variety of species including avian, swine, mouse, rat and human. Present investigation was carried out on a total of 1082 chicken belonging to seven genetic groups viz. Aseel (638), Kadaknath (755), desi (54), Black Australorp (603), the crosses of desi with other recognized breeds as Rhode Island Red (42), Black Australorp (62) and with Aseel (62) maintained at Avian Research and Development Centre (ARDC) of Ranchi Veterinary College, Birsa Agricultural University, Ranchi (Jharkhand). The data on various economic traits were recorded in all these genetic groups. Further the effect of chicken MHC genotype on growth and reproductive traits along with immunity of birds was also studied. The general performance were studied in all the seven genetic groups, while the relationship of chicken MHC with growth and reproductive performance were studied only on 50 chicken belonging to four purebred genetic groups.
