Effect of an antimicrobial association (Respirend-M) on productive performance of broilers (2201.04289v1)

Abstract: The objective of this study was to determine the effect of feeding an antimicrobial association to males broiler chickens from 0 to 14 days of age on the performance and clinical signs of bacterial processes. Two treatments were tested: a control treatment without Respirend-M, and a treatment with the antimicrobial (300 g/t Respirend-M, 0-14 d). 398 male Cobb 500 chicks were randomly assigned to two treatments and four replications per treatment. Body weight at 14 d, body weight gain, feed intake, feed conversion ratio, and health status were evaluated. The results showed feeding 300 g/t Respirend-M significantly (P<0.05) improved the final body weight, the body weight gain and the feed intake. No statistically significant (P>0.05) effect was detected on the feed conversion ratio.
