Abstract

Abstract: The objective was to determine the effects of the multi-carbohydrase Rovabio Advance on growth performance, mortality, and morbidity of wean to finish pigs. In the trial, 1, 260 DNA weanling barrows were fed from 5.9 kg to 133 kg live weight. Four diets were fed: positive control (PC), low nutrient density control (LNDC), PC with Rovabio Advance (PC+), and LNDC with Rovabio Advance (LNDC+). LNDC compared with PC contained 41 Kcal/kg less NE and 0.012% less SID lysine. Positive control diets contained 1.3% more added fat than LNDC. During each phase, all diets contained equal amounts of wheat middlings and corn DDGS, beginning at 3.75% each and increasing to 15% each. Each pen had 21 pigs each with 15 pens per dietary treatment. Pigs and feed were measured throughout all growth phases, as were the number and weight of dead pigs (mortality) and other pig removals (morbidity). Ten pigs per pen were harvested at 150 d on feed and the balance at 164 d on feed. Pigs fed PC vs LNDC had greater ADG and G:F and final live weight ( P < 0.01). Feeding Rovabio reduced pigs removed from test by nearly 40% (8.1 vs 4.9%, ( P < 0.03)). Standard deviation within pen of hot carcass weight tended ( P < 0.22) to be reduced by feeding Rovabio Advance and was reduced ( P < 0.03) by LNDC vs PC. Pig value per unit carcass weight was improved by Rovabio Advance ( P < 0.14) and by LNDC ( P < 0.01). In conclusion, feeding Rovabio Advance from weaning (5.9 kg) to finish (133 kg) decreases pig morbidity.
