GENETIC VARIATION IN GENES INVOLVES IN THE LIPID METABOLISM IN CUBAN ZEBU

The bovine species Bos indicus is more resistant than Bos taurus, essentially in tropical and subtropical atmospheres, reason why for its introduction in the improvement programs was necessary to increase the rusticity and the resistance of the genotypes specialized in milk production. The Cuban Zebu, result of the mixture of different indicus races (Gir, Guzerat, Nelore, Hindu Brazil and Brahman) has been the population bases to transform our unproductive cattle ranch, towards higher levels of meat and milk production, besides contributing the genes of resistance to tropical means. Until the moment, studies of functional analysis of key genes in the lipid metabolism have not been carried out in this genotype. With the development of the genomic and the techniques associated, it has been possible to know chromosomal regions responsible for a part of the genetic variance associated to a quantitative character of the different cattle species.
