This study aimed at mapping QTL (quantitative trait loci) using linear combinations of characteristics of economical interest in Gallus gallus. A total of 350 F2 chickens from an initial crossing among males from a broiler line (TT) with females from a layer line (CC) were used. It was conducted a QTL mapping in chromosomes of Gallus gallus (GGA1, GGA3, GGA5, GGA8, GGA11, and GGA13) for 20 performance and carcass traits. For detecting QTL, it was used the likelihood ratio test […]

Records of 844 animals of a F2 swine population were used to evaluate the association among four performance traits (litter size at birth, teat number, weight at 77 days of age, feed intake and feed:gain ratio from 77 to 105 days of age) and 17 carcass traits (slaughter age, right side carcass weight, carcass length by the Brazilian Carcass Classification Method, backfat thickness at boston shoulder area and the midline, loin depth, heart, spleen, kidney, cold right side carcass, ham, […]

The discriminatory potential of n-alkanes in tropical grasses (Brachiaria brizantha Stapf. cv. Marandu, Cynodon dactylon Pers. cv. Coast-cross 1 and Panicum maximum Jacq. cv. Tanzânia 1) and legumes (Arachis pintoi Koprov & Gregory. cv. Amarillo and Glycine wightii Verdc.) was evaluated. The forages were sampled in Spring, Summer and Winter, with four replications per species per season. The n-alkanes C24 to C35, using C32 and C34 as internal markers, were considered in the analyses. Concentrations of n-alkanes in these species […]
