Butirato de sodio en alimentación de pollos de engorde de la línea genética ROSS 308 AP A 2500 M S.N.M.

Abstract

The broiler chicken production industry has grown widely during these years, as it is an economical source of animal protein, due to its high nutritional content and its high demand worldwide. Finally, the objective of the research was to evaluate the effect of different levels of sodium butyrate in the diet of Ross 308 AP broiler chickens throughout their productive stages. The present study was carried out in an experimental farm located in the Ascázubi parish of the Cayambe canton located at 2500 m s.n.m.; T3 treatments were managed with different doses of sodium butyrate: T2 (500 g / t BS), T3 (1000 g / t BS) and T4 (2000 g / t BS) and a control T1 with 200 g / t of Enramycin, 80 chickens were evaluated per treatment with four repetitions of 20 animals, giving a total of 320 male chickens of Ross 308 AP genetics. The best result in terms of the weight variable was T3 (1000 g/t BS); for the ICA variable, the treatments were T1 (200 g/t EM) and T2 (500 g/t BS); the histopathological report did not report any pathological lesions in the small intestine and the microvilli did not present any alteration; a 0% mortality rate is reported due to the rigorous biosecurity of the facilities, feeding and management; finally, the analysis of the benefit/cost of the study considered that the treatments T2, T3 and T4 are profitable options to replace T1 with the antibiotic Enramycin, however, T4 had greater profitability according to the sale value per Kg of chicken.
