ESPINOZA C, Sandra et al. Productive performance of broilers supplemented with tylosin phosphate or enramycin as growth promoters. Rev. investig. vet. Perú [online]. 2019, vol.30, n.1, pp.483-488. ISSN 1609-9117.  http://dx.doi.org/10.15381/rivep.v30i1.15666.

The productive performance of broilers supplemented with tylosin phosphate and enramycin as growth promoters up to 42 days of age was evaluated. Four hundred male broilers were distributed into 4 treatments of 100 birds with 5 repetitions each. The treatments were: T1, control; diet without antibiotic; T2, diet with 8% enramycin in a dose of 10 ppm; T3, diet with enramycin 8% in a dose of 5 ppm; T4, diet with tylosin phosphate 25% in a dose of 55 ppm. The treated groups presented a higher body weight and better feed conversion index and European productive efficiency index than the control group; however, there were no differences in body weight gain, feed intake and mortality.

Keywords : tylosin phosphate; enramycin; growth promoters; broilers; productive performance.
