Reproductive behavior of the Cuban Zeme Bermejo of the Company Rescue Genetics of Sanguily of the municipality of Camagüey
Abstract
Records of 3,075 deliveries between the years 1981 - 2002 were used in the herd 22 of Cebu Bermejo of the Genetic Rescue Company of Sanguily, aged 28 to 256 months, with the objective of determining the influence of non-genetic factors : number of births (12), time (6), year of delivery (22) and sex of the offspring (2) and as genetic factor the stallions (35). For the statistical analysis a linear model was used by the method of Minimum Squares (SPSS, 2001), estimating the general means and their standard deviations for each trait studied. Reproductive traits period of service (PS) and labor-delivery interval (IPP) were significantly affected (P <0.01) for the time of delivery and the stallion for the number of services per gestation (S / G). The general averages and their standard deviations were: PS (287.6 ± 17.16 days); IPP (572.9 ± 36.18 days); DG (285.3 ± 3.28 days) and S / G (1.8 ± 1.04) inseminations performed).
