Dietary net energy for gilts from 25 to 100 kg body weight

ABSTRACT This experiment was conducted to evaluate the growth performance and carcass characteristics of gilts from 25 to 100 kg body weight (BW) fed diets with increased net energy (NE) levels. Seventy-two gilts with initial BW of 23.24±2.47 kg were allotted to one of six dietary treatments (2300, 2380, 2460, 2540, 2620, and 2700 kcal NE kg−1) using a completely randomized block design, with two pigs per replicate, and six replicates per treatment. Corn-soybean meal-based diets were formulated to be fed in three phases (25 to 50, 50 to 70, and 70 to 100 kg BW). Soybean oil was added to rep...
