Tasas de concepción, fertilidad y prolificidad en ovejas de pelo alimentadas con dietas enriquecidas con ácidos grasos polinsaturados

the conception, fertility and prolificacy rates were evaluated in hair ewes randomly distributed in: a control group (n = 72) that received 800 g dm of a commercial concentrate, a molasses group (n = 51) which was fed 717.6 g dm of the commercial concentrate + 80.25 g dm of cane molasses, and an oil group (n = 85) that was supplied with 726.8 g dm of the commercial concentrate + 30 g dm of corn oil as a source of polyunsaturated fatty acids. the conception and fertility rates were similar among treatments (p > 0.05). the prolificacy in the oil group (1.79) was higher (p > 0.05) than that in the molasses group and control groups (1.55 and 1.46 respectively). the addition of polyunsaturated fatty acids increased the rate of prolificacy in hair sheep.
