Seminal characteristics and lipids metabolites in hair rams supplemented with two types of fats

Abstract

The aim of this study was to determine the effect of the supplementation with palm oil (PO) and chicken fat (CF) on the seminal characteristics, testosterone, glucose and lipid metabolites levels in hair rams. Fats in the diet is the principal source of fatty acids and cholesterol (CHOL) for the steroid hormones synthesis involved in the reproductive processes. Seminal characteristics, levels of testosterone, glucose and lipids metabolites, body weight (BW), body condition score (BCS) and scrotal circumference (SC) were evaluated inhair rams supplemented with 30 g animal-1 d-1 of PO (n=4) or CF (n=4) for 90 d. Apart from semen vitality which was higher in CF group than in PO group, differences between treatments in any other parameter were not found. In hair rams, PO and CF can be integrated interchangeably in the diet without prejudice to the seminal characteristics, testosterone, glucose or lipid metabolites
