Abstract

The experiment was conducted to determine the effects of broiler chickens dietary kaolin, bentonite and zeolite supplementations on broiler thigh meat water holding capacity (WHC), lipid oxidation (TBARS), pH, and meat color during frozen storage. A total of 448-dayold sexed broiler cockerels were randomly assigned into 28 experimental units. A cornsoybean meal basal diet with 0, 15 and 30 g/kg kaolin, bentonite and zeolite as feed additive were added to control and 6 dietary treatments. Chickens were slaughtered and the left thighs kept at −20°C and analyzed after 1 and 150 days of storage. Experimental treatments had no effect on meat WHC, pH and color. Freezing at −20°C for 150 days impaired meat quality and caused chicken rancidity; however, lipid oxidation measured by TBARS value was significantly lower in chickens received diets including 15 g/kg bentonite and kaolin comparing to control diet after 150 days of frozen storage (P<0.05). It was concluded that though adding silicate minerals did not significantly influence WHC, pH and color in experimental treatments, they had influenced lipid oxidation and decreased chicken meat rancidity during frozen storage period
