Distribution of bovine lymphocyte antigen (BoLA-DRB3) alleles in Brazilian dairy Gir cattle (Bos indicus).
Brazilian dairy Gir (Bos indicus) cattle are a tropical, well-adapted breed, for which no information on the major histocompatibility complex (MHC) is presently available. The second exon of the bovine lymphocyte antigen (BoLA-DRB3) was amplified by polymerase chain reaction (PCR) of DNA samples from 28 Brazilian dairy Gir cows. Two experimental genotyping approaches were used: direct sequencin...

متن کاملGenetic Variation of the Major Histocompatibility Complex DRB3.2 Locus in the Native Bos indicus Cattle Breeds
The major histocompatibility complex (MHC) plays well-defined roles in eliciting immune responses and combating infectious diseases. The major histocompatibility complex of cattle is referred to as BoLA (Bovine Lymphocyte Antigen). This genetic system is among the most polymorphic. In the present study, polymorphism of the BoLADRB3.2 locus in three Bos indicus breeds viz., Sahiwal, Rathi and Ha...
متن کاملSeasonal effects on milk yield, erythrocytic and leukocytic indices of Kankrej cattle (Bos indicus)
Materials and Methods Mammals, including ruminants, exhibit seasonal rhythms of physiological functions to cope with climatic fluctuations in order to establish equilibrium [1]. The seasonal rhythms reflect the ability of endogenous adaptive mechanism of animals to react in advance to environmental changes associated with seasons [2]. In fact, physiological equilibrium is maintained by blood an...
متن کاملCharacterization of yolk sac proteins of Bos indicus cattle embryos.
The yolk sac is an embryonic membrane that is essential for the embryo's initial survival in many mammals. It also plays an important role in the production of proteins necessary for development. We studied proteins of the yolk sac in bovine embryos at up to 40 days of gestation. We examined the yolk sac of 17 bovine embryos at different gestational periods, measuring α-fetoprotein, α-1-an...
