We investigated the effects of supplementing low energy diets with lysolecithin and sodium stearoyl-2-lactylate on growth performance and nutrient digestibility in broilers. A total of 768 1-d-old Ross 308, mixed gender broiler chicks with an average initial body weight of 44.3 g, were used in a 35-d feeding trial. Broiler chicks were sorted into pens with 16 birds per pen and every treatment consisted of 12 pens (192 chickens per treatment). Treatments were: 1) PC: basal diet, 2) NC: PC-100 kcal, 3) T1: NC+ 0.08% lysolecithin, and, 4) T2: NC + 0.04% sodium stearoyl-2-lactylate. Body weight gain (BWG), feed intake (FI) and feed conversion ratio (FCR) were measured on a weekly basis. Chromium oxide was added to the diets at 0.2% on the last week of the experiment, as a marker for digestibility. Dietary treatments had no effect on growth performance for days 1 to 21. Low energy diet supplemented with lysolecithin and sodium stearoyl-2-lactylate in phase 2 (d 21 to 35) improved body weight gain (P<0.05). Addition of lysolecithin and sodium stearoyl-2-lactylate to the diets improved the digestibility of energy and nitrogen (P<0.05), but digestibility of dry matter was not affected. Overall, addition of an emulsifier to the diet of broiler chickens in the late growth phase enhanced growth performance and digestibility of energy and nitrogen.
