Evaluation of the productive characteristics of the Caqueteño Creole cattle breed

Abstract

The objective of this research was to evaluate the productive and reproductive characteristics of the Caqueteño Creole cattle breed. Data was taken from 655 animals organized into 6 groups: group 1 (n = 185), pure Caqueteño Creole cattle breed (Caqueteño); group 2 (n = 34), Caqueteño Creole cattle breed crossing for multiracial animals (Caqueteño 50% × multiracial 50%); group 3 (n = 10) (Caqueteño 75% × Bos indicus 25%); group 4 (n = 56), crossbreed F1 (Bos taurus × B. indicus); group 5 (n = 168), animals with B. taurus percentage greater than 50% (B. taurus > 50%); group 6 (n = 202), animals with B. indicus percentage greater than 50% (B. indicus > 50%). Subsequently were done descriptive statistics and analysis of variance (ANOVA) with the LSD Fisher test (P < 0.05), with the software InfoStat version 2018. A significant difference was found (P < 0.05); in weight at birth (WB), Caqueteño presented the smallest value (29.8 kg); in daily weight gain (DWG), weight adjusted at 9 months (W9), and weight adjusted at 18 months (W18), Caqueteño presented highest values corresponding to 574.5 g/day, 183.0 kg, and 343.6 kg, respectively; in age at the first service (AFS), the lowest value was obtained by B. taurus × B. indicus (24.5 months), and in calving interval (CI), no significant differences were found (P > 0.05). In conclusion, the Caqueteño Creole cattle breed is efficient in the productive variables (daily weight gain, adjusted weight at 9 and 18 months); in age at the first service, the F1 group indicated precocity, followed by Caqueteño Creole.
