A sample of 192 male broiler chickens<br>(Ross 308) were divided into 2 groups (each group consisting of 8 replicates of 12 chicks each) as: 1) control group,<br>without Mg supplementation in the drinking water; and 2) Drinking Mg group, 10 mg of Mg/L was added into 1 L of<br>their drinking water. It was shown that supplementing Mg in the drinking water significantly reduced body weight (P<br>= 0.04) and tended to decrease feed intake (P = 0.08) between 1-21 days of age, and significantly reduced water intake<br>(P = 0.02) and tended to reduce body weight (P = 0.06) between 21-35 days of age. For the overall period (1-35 days),<br>water intake significantly decreased (P = 0.02) and the mortality rate tended to increase (P = 0.06) when Mg was<br>supplemented in the drinking water. Carcass and meat quality were not significantly influenced by Mg<br>supplementation. Furthermore, the </span><span class="fontstyle2">E. coli </span><span class="fontstyle0">population in the caecum was not significantly changed by the<br>supplementation. In conclusion, supplementing Mg in drinking water at 10 mg/L showed negative effects on growth<br>performance due to the reduction of water intake but had no significant effects on carcass and meat quality nor on </span><span class="fontstyle2">E.<br>coli </span><span class="fontstyle0">in the caecum.</span> </p>}, number={4}, journal={The Thai Journal of Veterinary Medicine}, author={Namted, Siriporn and Rakangthong, Choawit}, year={2020}, month={Jan.}, pages={353–359} }
