ABSTRACT This study aimed to evaluate the effects of lysine (Lys) restriction on compensatory growth, body composition, and nitrogen balance of growing-finishing pigs before and after immunocastration. Sixty-four entire male pigs (39.2 ± 6.8 kg) were randomly assigned one of four treatments: Control diet (CON; no restriction) or diets with restriction of Lys level in 14 (Lys-14), 28 (Lys-28) and 42% (Lys-42) of estimated Lys requirements for entire growing pigs (Lys restriction phase, from 0 to 28 d). From 29 […]

ABSTRACT The objective was to group and characterize Zebu cattle carcasses according to sex. Data from 15,002 carcasses of cattle raised in the semiarid region of the state of Minas Gerais, Brazil, were used. The carcass characteristics analyzed were weight, conformation, subcutaneous fat, number of permanent incisor teeth (PIT), and sex (uncastrated males, castrated males, females (up to six PIT), and cows (eight PIT)). Cluster analysis was applied to establish the relationship between sex and carcass characteristics. Four clusters were […]
