This investigation measured the kidding rate achieved by high-performance ranked bucks after evaluation in a competitive serving capacity test (SCt). The study was conducted at Embrapa Caprinos e Ovinos and Fazenda São João, semi-arid region of Northeastern Brazil. Six Anglo-nubian bucks were ranked as top (TOP) and above average (ABO) after a SCt and then individually joined over a 63-day period to six mating groups with different male: females ratio (M:F; 1:30 or 45 or 60). Kidding rates did not differ between ranks but tended (P <0.10) to differ among ratios and varied from 72.4% to 93.0%. Disregarding the rank of males, kidding rate observed up to 21 days of the season was unaffected by M:F, which affected cumulative kidding rate up to 42days (P <0.05) and 63days (P <0.01) of the season. Kidding rate varied throughout the kidding season regardless rank of the buck or M:F ratio. Ranking males into TOP and ABO categories was not efficacious to detect differences in breeding performance at tested M:F ratios. Therefore, SCt was capable to indicate males able to mate, but it did not accurately predict the fertility of individual bucks. |
