Recent cytogenetic studies in the genus Brachiaria using germplasm collected from wild African savannas in the 1980s revealed that most species and accessions within species are polyploid. Diploid, tetraploid, and pentaploid accessions have been found. We found asynch...
متن کاملLipid Oxidation in M. longissimus dorsi and M. semimembranosus in Lambs Reared Indoors and on Pasture
Lipid oxidation was studied in M. longissimusdorsiand M. semimembranosusin male lambs of Northeastern Bulgarian Fine Wool Breed and cross of this breed with Ile de France, reared indoors and on pasture.
