ABSTRACT
The following is a description of the results obtained from broilers in a farm in the capital of the Province of Corrientes, Argentina. These broilers were given organic chelates (QMD) in the drinking water. Nine hundred broilers from the same origin (3 lots of 300 birds each) were divided at random at the beginning of the cycle into 2 Groups (A and B). Group A continuously received the supplement (QMD-base) in a dose of 1.36 mg/kg weight per day, whereas Group B acted as the control one. Body weight, feeding and death percentage were weekly registered. In order to evaluate results on weight differences, and the change of feeding procedures between treatments, the randomized block variance analysis was employed to test the significance of the results, contrasting the hypothesis with a 5% alpha. Corresponding average marks in body weight were 2 380, 2 419.5 and 2 343 g in the broilers’ treated group, and 2 290, 2 396 and 2 267.5 g in the control one. No statistical differences were found regarding death percentage. There was an average difference of 79.33 g in the live weight groups, and a meaningful improvement of 0.09 in the feeding conversion rate in the treated broilers. Based on the statistical analysis it is inferred that birds treated with QMD-base presented improvement in weight gains and feeding conversion, compared with non treated birds under the described experiment conditions. Weight gains were of 56.25 to 102.41g, and feeding conversion improvements of 0.015 to 0.165, respectively.
