چکیده مقاله:

The hypothesis of this experiment was that the various sources of dietary fat with different dietary ratios of polyunsaturated fatty acids (PUFAs) to saturated fatty acids (SFAs) would alter the reproduction parameters of mature rams. Twelve mature rams were randomly allotted to one of four dietary treatments in a completely randomized design. Dietary treatments were: 1) ration with 4% soybean oil (SOY-OIL), 2) ration with 8% full fat soybean (FULL-FAT), 3) ration with 4% calcium salts of soybean oil (Ca-SALT) and 4) ration with 4% tallow (TALL). All diets were kept isoenergetic and isonitrogenous and formulated to be similar in Ca and P contents, while meeting or exceeding the Cornell Net Carbohydrate and Protein System software requirements for the rams used in this study. Diets were supplied to the rams during four months (from August to late December). Semen characteristics, scrotal circumference, and concentrations of cholesterol, low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglyceride and testosterone of plasma were measured at the end of the experimental period. Based on the results of this study, diets supplemented with Ca-SALT and TALL improved the health of plasma membrane, viability and sperm concentration (P0.05). As an overall conclusion, the results of this study have indicated the benefits for adding Ca-SALT to the diets of adult rams on their reproductive performance.
