Abstract

This study was conducted to evaluate growth performance of weaned pigs using diets based on ideal protein of the Korea swine feeding standard (KFS) and US the nutrient requirements of swine (NRC). A total of 96 weaned (initial body weight of 6.12 ± 1.21 kg) pigs were randomly allocated into 2 dietary groups with 12 pens per diet (4 pigs·pen-1) in a completely randomized design. The dietary treatments were corn and soybean meal-based diets formulated by the KFS and NRC nutrient requirements estimates for weaned pigs. Experimental diets were fed for 6 weeks in 2 phases feeding program based on age: 1) Phase 1 = week 1 to 3 (21 days); 2) Phase 2 = week 4 to 6 (21 days). During Phase 1 and 2, there were no differences (p > 0.05) for the initial and final body weights between the KFS and NRC groups. Additionally, the average daily gain (ADG), average daily feed intake (ADFI), and gain to feed ratio (G : F) during overall experimental period were not different between the groups. In conclusion, weaned pigs fed the diet based on the KFS had a similar body weight and growth performance to those fed the diet based on the NRC. This suggests that the Korea swine feeding standard may be used for the diet formula of weaned pigs in Korea swine production compared with the US nutrient requirements of swine.
