Ovarian function and pregnancy of dairy goats supplemented with pequi oil

Abstract

The objective of the work in question was to evaluate the ovarian function of Saanen goats supplemented with pequi oil. The experiment was carried out at the IFCE Ovine Caprinoculture vivarium, campus Crato. Eight pure Saanen goats were used, weighing an average of 1025,15 pounds, distributed in a completely randomized design with two treatments. The first treatment constituted soy oil as the lipid source and the second treatment with pequi oil. Two estrous cycles were evaluated to analyze the reproductive parameters of the females. In the first cycle, a non-castrated sheep was used as a ruffian to identify estrus, and the ovarian function was evaluated for the presence and number of follicles by ultrasound. In the second cycle, a Saanen was used in order to mate with the females. Ultrasound was performed to assess conception, fertility and prolificacy rates. The computer software SAEG 9.1 was used to analyze the values obtained. It was found that females supplemented with soybean oil stood out in comparison to goats treated with pequi oil, except for body weight, follicular diameter and body condition score, concluding that the use of pequi oil for Saanen goats it presents itself as an economically unfeasible alternative, as it has a higher acquisition value.
