This study aimed to evaluate the effect of two ratios of male to females in Canindé goats under free mount regime kept on 'caatinga' and supplemented with multiple mixture on the reproductive performance and the growth pattern of offspring from birth until weaning. The data were submitted to ANOVA and means compared by Tukey test at 5.0% level of significance. The mean fertility of goats by ultrasound (94.05%) and parturition (85.71%) did not show difference between treatment T0 and TI (P>0.05). The body condition of the goats before the onset of breeding season influenced the fertility evaluated by ultrasound; the type of birth influenced the weight at birth until weaning at 84 days, but sex just affected the weight at 28 days when males were with more weight than females while the use of multiple mixture was compatible with high fertility.
