Abstract

The objective of this study was to determine the effects of silicon oxide in broiler chickens drinking water on performance and litter quality. A total of 120 day old mixed sex broiler chicks were randomly divided into 4 treatments and 3 replications, with 10 birds in each replicate. The birds were distributed into a completely randomized experimental design, with 4 silicon levels (0, 1.5, 2.0 and 2.5 mg of silicon oxide/100 kg body weight (BW)/day).Diets were maize and soybean meal based and formulated for starter (1–21 day), and finisher (24–49 day) phases. Birds were provided with water freely. The average daily temperature and relative humidity inside the poultry house were 35.9 °C and 36%, respectively. For the starter phase silicon oxide in broiler chickens’ drinking water at 200mg/100kg body weight/d increased (P < 0.05) final body weight and average weight gain (991.00g and950.96g respectively) compared with the control (778.57 g and 738.54 respectively). The inclusion of 200 mg silicon oxide/100kg body weight/d in water improved feed conversion ratio compared to the controls (P < 0.05) and significantly reduced feed cost per kg gain. For the finisher phase, 10mg/100kg body weight/d and 15mg/100kg body weight/d had similar results for final weight, weight gain and feed cost per kg gain. However, inclusion of silicon in broiler chickens water improved litter quality. In conclusion, silicon oxide in broiler chickens drinking water at 1.5mg/100kg body weight/d enhanced growth performance, improved feed conversion ration and litter quality as well as reduced feed cost per kg gain at the starter and finisher phases respectively.
