Effects of sugar beet pulp and expansion on performances of lactating sows and nursery piglets

Abstract Text: Ninety-six PIC lactating sows were divided into 6 treatments with 16 sows per treatment, they were fed diets containing 0, 5, or 10% of sugar beet pulp for 21 d. Three treatment diets were pelleted, and the other 3 diets were expanded and then pelleted. The diets contained the same calculated levels of CP and DE, sows were fed 3 times daily. On day 21, piglets were weaned and performances of lactating sows and nursery piglets were recorded. Results indicated that total weaning weight of piglets per litter and average daily weight gain of piglets were 50.47±6.14 kg/litter and 201.70±30.17 g/piglet; 51.07±11.04 kg/litter and 189.04±45.89 g/piglet; and 53.43±12.31 kg/litter and 207.27±41.79 g/piglet for sows fed diets containing 0, 5, or 10% of pelleted sugar beet pulp, respectively; and total weaning weight of piglets per litter and average daily weight gain of piglets were 62.19±12.56 kg/litter and 222.38±36.75 g/piglet; 47.97±10.63 kg/litter and 198.13±47.15 g/piglet; and 53.75±7.35 kg/litter and 193.81±36.30 g/piglet for sows fed diets containing 0, 5, or 10% of expanded and then pelleted sugar beet pulp, respectively. Results also indicated that expansion has significant effects on sow feed intake, total weaning weight of piglets per litter and average daily weight gain of piglets (P<0.05), feed intake was 3.26±0.90 kg/d and 4.77±0.71 kg/d, for sows fed pelleted and expanded diets, respectively; total weaning weight of piglets per litter was 50.47±6.14 kg/litter and 62.19±12.56 kg/litter for sows fed pelleted and expanded diets, respectively; and average daily gain of piglets was 201.70±30.17 g/d and 222.38±36.75 g/d for sows fed pelleted and expanded diets, respectively. There were no internations between sugar beet pulp and diet forms (P>0.05).
