Abstract:

This study was designed to investigate the effects of hydrated sodium calcium aluminosilicate (HSCAS) and yeast glucomannan (YGM) on broiler chicks raised under different environmental conditions. Completely randomized 2×6 two-factors design was performed with 720 new born healthy Cobb-500 broilers divided into 2 raising rooms with different environmental conditions. Broilers in each raising room were randomly divided into 6 treatment groups with 6 replicates/treatment and 10 birds/replicate. Treatment groups were provided with different diets as follows: 1) normal basal diet (the positive control group), 2) mould-contaminated diets containing AFB1 22.7 µg/kg, OTA 2.4 µg/kg, T-2 3.8 µg/kg (the negative control group); 3) normal basal diets supplemented with 0.05% YGM, 0% HSCAS; 4) normal basal diets supplemented with 0.05% YGM, 1% HSCAS; 5) normal basal diet supplemented with 0.05% YGM, 1.5% HSCAS; 6) normal basal diet supplemented with 0.05% YGM, 2% HSCAS. All chicks were slaughtered until day 42. The results were as follows: 1) compared with the negative control group, ADG was increased by 23.3% and F/G was decreased by 23.0% in group 5; 2) serum biochemical indexes were significantly improved after the addition of mycotoxin adsorbent; 3) apparent metabolic rates of CP, EE and Ca of feed in group 6 were increased by 32.97%, 10.37% and 6.7%, respectively, comåpared to the negative control group; 4) all indexes including growth performance, serum biochemical parameters, nutrients metabolic rate and AFBI residues of chicks raised under the clean environmental condition were better than that under the poor condition (P<0.01) and a significant interaction between mycotoxin adsorbent and the environmental condition was observed.
