Reproductive evaluation of Charolais and Charbray bulls on the reproductive efficiency of herds in the humid tropics of Veracruz

Objective: To analyze the breeding soundness examination (BSE) of the Charolais and Charbray breeds in the humid tropics on the efficiency of herds to determine differences between breeds. Design / methodology / approach: Results of the BSE of N = 90 Bulls, Charolais (n = 33) and Charbray (n = 57) breeds, evaluated in situ during the years, 2017-2019. Bull (age, body condition score, libido and scrotal circumference), semen (concentration, motility and volume), herd (pregnancy rate and calve interval) and environmental variables (season: dry and rainy) were analyzed with ANOVA One-Way, factorial, multiple regression and multivariate analyses, using STATISTICA v10 software. Results: Charolais and Charbray bulls show similar results in BSE (p> 0.05) in tropical environmental conditions. Limitations / implications: Seasons and do not affect (p <0.05) the BSE. Libido, a variable not systematically included in the BSE is associated (p <0.05) with age (R = -0.42), motility (R = 0.67), sperm concentration (R = 0.66) pregnancy rate (R = 0.63) and clave interval (R= -0.33). Findings / conclusions: Variables with high association with the gestation rate were: age (R = -0.50), libido (R = 0.63), motility (R = 0.60) and sperm concentration (R = 0.51). Variables with high association (p <0.05) with the calve interval were: age (R = 0.74) and libido (R = -0.33). The environmental variables did not affect the ECR of the Charolais and Charbray bulls in a different way.

Objective: To correlate the Breeding Soundness Evaluation (BSE) of Charolais andCharbray bulls in the warm subhumid climate and its effect on the Pregnancy rate andCalving interval of herds to estimate differences between breeds.Design/methodology/approach: BSE was carried out on N = 90 Bulls; Charolais (n =33) and Charbray (n = 57), evaluated in situ during the period 2017 to 2019. Bull (age, body condition, libido, and scrotal circumference), Semen (concentration, motility, and volume), Herd (Pregnancy rate and Calving interval) and environment variables (Rainy and Dry season) were analyzed with the one-way ANOVA, Factorial, Multiple regression, and Multivariate analysis.Results: Charolais and Charbray bulls show similar results in the BSE (p>0.05) in awarm subhumid climate.Limitations/implications: Year season (Rainy or Dry) do not affect (p<0.05) the BSErating. Libido is associated (p<0.05) with age (R=-0.42), sperm motility (R=0.67), spermconcentration (R=0.66) and pregnancy rate (R=0.63). Findings/conclusions: Variables with high association (p<0.05) with pregnancy ratewere libido (R=0.63), motility (R=0.60), sperm concentration (R=0.51) and age (R=-0.50); variables with high association (p<0.05) with calving interval were: age (R=0.74)and libido (R=-0.33). Charolais and Charbray bulls show similar reproductive efficiencyin herds under a warm subhumid climate in Veracruz.
