Effects of supplemental fat to low metabolizable energy diets on cholesterol and triglyceride contents of broiler meat.

摘要: Problem statement: Modern diets high in Saturated Fatty Acids (SFA) and low Monounsaturated (MUFA) Polyunsaturated (PUFA) fatty acids are mostly blamed for the increased incidence of cardiovascular diseases. Since dietary absorbed by monogastric animals deposited their tissues without significant modification, considerable potential exists manipulation acid profile poultry meat eggs. In present study, effects different sources levels supplemental fat to energy on protein intake efficiency during grower finisher periods cholesterol Triglyceride (TG) contents breast thigh broiler chicks were investigated. Approach: One hundred eighty 1 day old Ross 308 both sexes used 42 days. The randomly allocated 15 pens containing 12 each with 3 replicates assigned receive one 5 treatments 2 (soybean oil beef tallow) (20 40 g kg-1) a completely randomized design factorial arrangement. There was also control treatment (without fat) this experiment. All fed commercial starter diet from 1-10 day, where-after isocaloric isonitrogenous diets. Results: differences among all phases experiment (p<0.05). Energy significantly higher kg-1 soybean that compared other groups. effect TG age Adding 20 decrease highest value observed groups Conclusion: Supplementation improved efficiency, decreased content comparison
