Abstract
The objective of this study was to determine the birth weight of Creole and MEVEZUG lambs according to sex and type of calving. The records of the former correspond to the years 2006 to 2010 and the later from 2010 to 2019. 1 176 records of data from an ovine herd composed averagely of 110 heads of sheep were analyzed. The sheep of the first years were of different colors as a result of the crossbreeding among the Pelibuey, Black Belly, Dorper and Katahdin breeds, while those of the later were of pure color (light brown and tobacco brown) produced from the selection of the inbred cross of the first period herd. The feeding of sheep through the entire study period based on grazing native meadows and irrigated areas in the dry season, at the time of least forage availability. They were provided with 100 grams of corn grain per animal. The collected data were subjected to analysis of variance and the means were compared by the Tukey and Duncan test (P <0.05) using the statistical software infoStat. Average of male weighed was 2.96 kg with (P <0.0001) and 2.67 kg for females compared to MEVEZUG being 2.65 kg for males and 2.59 kg for females (P> 0.2819). In relation to the type of delivery, the values were 3.23, 2.69, 2.13 and 1.95 kg (P <0.0001) for single, double, triple and quadruple deliveries, respectively for Creoles and 2.98, 2.39 and 1.97 kg (P < 0.0001) for singles, doubles and triples, respectively for MEVEZUG lambs. It is concluded that the weights of the male and female lambs were heavier for the Creoles compared to the MEVEZUG.
