Influência da temperatura sobre a reprodução de Coelhos

Abstract

This paper describes the activities carried out during the internship and a case study developed during it. The internship took place at the Veterinary School Farm and lasted 90 days (November 2023 to January 2024), with the aim of consolidating theoretical and practical knowledge about raising rabbits in total confinement, through monitoring and participating in the daily activities that take place in the rabbit hutch. Among the practices carried out, the activities of checking the flock, health management, feeding management, reproductive management and prophylactic management stand out. For the case study, individual zootechnical control spreadsheets from previous years (2022 to 2023) were used, where 8 breeders were evaluated regarding conception rate, birth rate, weaning rate and fertility. The parameters were calculated individually for each season, with April, May, June, July and August being considered winter months and September, October, November, December, January, February and March being summer months. Having obtained the results of the individual parameters, the averages of the parameters of all the does in each season were obtained. From the analysis, an average conception rate of 92.6% + 12.97, a birth rate of 76.62% + 11, a weaning rate of 95.75% + 21.03 and a fertility rate of 86.5% + 1.76 for the winter season were obtained. For the summer, a conception rate of 70.87%+_24.79, a birth rate of 72.18%+_22.22, a weaning rate of 85%+_22.5 and a fertility of 75.5%+_0.50 were obtained. In general, the adverse environmental conditions of the summer led to a decrease in reproductive activity in the summer compared to the winter, negatively interfering in the results expected for this season (summer). Therefore, it is recommended that the FAVET farm adopt strategic measures to reduce heat stress, which in turn compromises the reproductive rate in periods of higher temperatures. (TRADUÇAO NOSSA)
