Additive Effects of Dietary Supplementation with Zeolite and Methyl-Sulfonyl-Methane on Growth Performance and Interleukin Levels of Broiler Chickens.

ABSTRACT: Silicate minerals are common additives in poultry feed. To assess their effects, we added zeolite (ZEO) and methyl-sulfonyl-methane (MSM) to broiler chicken diets. A total of 960 one-day-old Ross broiler chicks were randomly divided into four dietary groups with six replicates. Each broiler was maintained until it reached 35 days of age. A completely randomized 2 × 2 experimental design was used, with two ZEO (0 and 1.0%) and two MSM (0 and 0.10%) levels. We observed an additive effect (P<0.05) on interleukin-2 (IL-2) concentrations in broiler bursa and serum when both ZEO and MSM were present. Both ZEO or MSM produced significant (P<0.05) increases in body weight, weight gain, and feed intake. Both increased IL-2 and IL-6 levels in the bursa and serum. Neither affected the s
