Respuesta de un promotor de crecimiento en cerdos landrace x pietrain en la fase de crecimiento

The research was conducted at the experimental farm "La María" in the Programa de Producción Porcina, part of the Universidad Técnica Estatal de Quevedo (UTEQ), located at Km 7 via Quevedo - El Empalme. The effect of growth promoting Flavomycin on three levels, with the following treatments were evaluated: (T0) without the use of growth promoter; (T1) with the addition of 300 g / ton of feed; (T2) with 500 g / Ton and (T3) with 700 g / Ton. One Completely Random Design (CRD) with four replications was used. The variables evaluated were: weight gain, feed intake (kg / day) and feed conversion. 16 pigs Landrace x Pietrain, weaned at 28 days of age with 6.83 ±1.08 kg were used. No differences (p> 0.05) in the variables evaluated were found. The weight gain was higher in the treatment including 300g / ton (0.342 kg) of growth promoting dietary this variable, it decreased as increased the level of inclusion of Flavomycin, however superior to the control. Feed intake was directly proportional to the insertion of Flavomycin, obtaining a consumption of 0.437 kg / day at the highest level of growth promoter (700 g / Ton) versus 0.420 kg / day, the lowest level (300 g / Ton) and 0.400 kg / day promoterless witness. The best feed conversion was obtained with the addition of 300 g of Flavomycin / Ton of food (1.22), increasing the level of this growth promoter generated an increase in this indicator even higher than the control group. By not observe significant differences (p> 0.05) in the level of inclusion of Flavomycin in the diet of growing pigs Landrace x Pietrain, research of alternative growth promoters is recommended.
