Limited research has been performed using sunflower seeds as an ingredient in swine diets. Because of the large amount of sunflowers produced in South Dakota, it would be beneficial to determine their usefulness as a feed ingredient in livestock rations. Work conducted at North Dakota has shown levels of over 10% sunflower seeds in diets of growing- finishing pigs produced oily carcasses. Previous research at this station (SWINE 80-8) has shown the maximum level of ground, whole sunflower seeds to be fed to sows during late gestation and early lactation is between 25 and 50%.
In order to utilize sunflower seeds in swine diets more efficiently, the digestibility of the various nutrient fractions of the seeds must be determined. This study was performed to determine the coefficients of apparent digestibility, digestible energy and nitrogen retention for rations containing various levels of ground sunflower seeds.
