Resumen

Para evaluar si el nivel nutricional modifica la calidad seminal y el comportamiento sexual de los machos cabríos tratados con días largos artificiales. Diez y seis machos cabríos fueron divididos en dos tratamientos difiriendo en su nivel alimenticio. Un grupo de machos recibió el 75 % de sus requerimientos nutricionales de mantenimiento y reproducción (G-75), mientras que otro grupo recibió el 120 % (G-120). La circunferencia escrotal fue menor en el grupo G-75 que la registrada en el grupo G-120 (P < 0.01). Similarmente, el volumen de eyaculado y el número total de espermatozoides por eyaculado fueron menores en el grupo G-75 (0.5 ± 0.05 mL y 1.9 x 109, respectivamente) que en el grupo G-120 (0.7 ± 0.1 mL y 3.0 x 109, respectivamente; P < 0.001). La motilidad espermática fue menor en el grupo G-75 (2.6 ± 0.1), que en el grupo G-120 (3.2± 0.1; P < 0.001). La latencia a la eyaculación fue mayor en los machos del grupo G-75, que la registrada en el grupo G-75 (P < 0.001). Los resultados del presente estudio indican que, en los machos cabríos tratados con días largos artificiales, la reducción de un 25% de sus requerimientos nutricionales afecto la calidad seminal y el comportamiento sexual.
