Effectiveness of emulsifier and carbohydrase in Lupinus albus seed-rich diets on digestibility, some physiological indicatorsand performance of growing pigs

The study aimed to evaluate the impact of emulsifier and/or carbohydrase additives on the production performance of growing pigs offered a diet with a high proportion of white lupine seeds cv. Butan. The experiment involved 49 Naïma × P76 male piglets with an initial body weight of 10.5 kg divided into seven groups. The control group was fed a diet without any additives, whereas the remaining groups received diets with the addition of emulsifier, β glucanase, and β-xylanase separately or in combination. The apparent ileal digestibility coefficients of crude protein were significantly improved (P < 0.05) by all additives, although no significant differences were observed in dry matter and ether extract digestibility (P > 0.05). Both to the performance results and ammonia concentration, pH, and digesta viscosity (P > 0.05), were not different when these feed additives were used. The most promising effects on nutrients digestibility and performance were obtained were emulsifier, β-glucanase and their blend were added to the feed mixtures.
