Campero INTA is a type of bird with a slower growth rate than commercial broilers with a standardised production protocol; however, the protocol does not establish conditions related to sex separation during breeding. The aim of this work was to evaluate the effect of sex separation on body growth pattern, uniformity by precision, body conformation and slaughter traits in the three-way experimental cross Campero Casilda chickens. The birds were kept in confinement as a single group until 35 days of age and then separated into two treatments (mixed and single sex) during the free-range stage, between 36 days and slaughter at 77 days of age. Sex separation was advantageous for males which evidenced greater asymptotic weight and lower maturation rate, suggesting better feed efficiency. In addition, sex separation in males did not affect body weight at slaughter age or carcass yield and resulted in a greater proportion valuable muscle cuts and a lower proportion of body fat. On the other hand, females raised alone, evidenced lower asymptotic weight, and a higher maturation rate, suggesting lower feed efficiency. In addition, they reached a lower weight at slaughter age and, although they had a lower fat content and an equal proportion of thigh, showed a slight decrease in the proportion of breast and a reduction in yield.
