Digestibility of Carrot Meal in Swine

Abstract

The study was conducted at Banig, Tawang La Trinidad ,Benguet on February 2012 to determine the digestibility coefficient of nutrients in diets supplemented by carrot meal in swine and determine the digestibility coefficient of nutrients of carrots. A total of nine heads of crossbreed (Duroc x Largewhite) female finishing pigs at an average of 85kg were randomly distributed into three treatments and each treatment was replicated three times with one pig per replicate to make a total of three pigs per treatment. The treatments were: pure commercial feeds, 200g carrot meal/ kg of commercial feeds, and pure carrot meal. Analysis showed carrot meal contains 85.53% for dry matter, 9.49% for ash, 6.70% for crude protein, 2.43% for crude fat, 15.35% for crude fiber, 51.56% for nitrogen free extract, and for 3,380 kcal GE/kg. Results showed that supplementing carrot meal to pigs had effect on the apparent digestibility and digestibility nutrient per kilogram in ash, crude protein, crude fat, gross energy, nitrogen free extract, dry matter, and crude fiber. The digestibility of nutrient in carrot meal are as follow 91.87% for dry matter, 88.03% for ash, 74.21% for crude fat, 94.18% for nitrogen free extract, 92.21% for crude fiber and 90.977% for gross energy. While statistical analysis revealed significance differences between the treatments in terms of ash, crude protein, crude fat, gross energy, nitrogen free extract, and dry matter for apparent digestibility, it also revealed significant differences among the treatments in terms of ash, crude protein, crude fat, and crude fiber for digestible nutrient. The digestible nutrient of carrot meal was computed as follows: 141.54g dry matter, 83.54g ash, 57.010g crude protein, 18.03g crude fat, 485.61g nitrogen free extract 141.54, and 3073g gross energy. Differences among the treatment in terms of digestible nutrient per kilogram are not significant for gross energy, nitrogen free extract, and dry matter.
