To evaluate Calcium Stearoyl-2 Lactylate (CSL) performance as an exogenous emulsifier together with lipase for broiler diets.
In total, 252 one-day-old Ross 308 broiler chickens were allocated in a completely randomized design to give 6 replications per treatment with 7 birds in each cage. There were six dietary treatments representing a 2 × 3 factorial arrangement consisted of two energy levels [standard energy (PC) and -100 kcal/kg of the requirement level (NC)] and three dietary treatments [without additives (CON), CON+CSL (CSL) and CON + CSL + Lipase (CSL-Lipase)]. Corn and soybean meal-based experimental diets containing vegetable oil were formulated. Growth performance, blood parameters, visceral organ weights, ileal morphology, nutrient digestibility, and cytokine gene expression were measured.
Birds fed a diet including CSL increased (P<0.05) lipase level in blood compared to birds fed a diet including CSL-Lipase on day 21. Similarly, higher (P<0.05) liver weight was observed in birds fed a diet including either CSL or CSL-Lipase on day 21. Birds fed NC diet with CSL improved (P<0.05) nutrient digestibility compared to the NC diet on day 21. However, birds fed a diet supplemented with CSL or CSL-Lipase did not affect (P>0.05) the weight gain, feed efficiency, ileal morphology, and cytokine concentrations during the experiment period, regardless of dietary energy levels.
Our results indicated that CSL has a role in improving nutrient digestibility in young birds when supplemented to a corn-soybean meal based broiler diet.
