Response of a growth promoter in growing pigs in the growth phase

Abstract

This research was carried out at the experimental farm "La María" belonging to the State Technical University of Quevedo (UTEQ), located at km 7 of the Quevedo - El Empalme road. The effect of the growth promoter Flavomycin was evaluated at three levels, with the following treatments: (T1) without the use of the growth promoter; (T1) with the addition of 300 g/ton of feed; (T2) with 500 g/Ton and (T3) with 700 g/Ton. A Completely Randomized Design (CRD) was applied with four replicates and four replicates. The variables evaluated were: weight gain, feed intake (kg/day) and feed conversion. Sixteen CRIOLLOS
pigs, weaned at 28 days of age and weighing 6.83 ± 1.08 kg, were used. For weight gain, significant statistical differences were found between treatments according to Tukey's test (P?0.05), with the best control treatment without promoter T0 with (13.33) total weekly gain, followed by treatment T2 500g/Ton with (13.29) total weekly gain. With respect to feed consumption, significant differences were found among the treatments under study according to Tukey's test (P?0.05), having a higher consumption the treatment T2 500/Ton with (42.81) total weekly, followed by the control treatment without promoter T0 with (42.35) total weekly. Regarding feed conversion, significant differences were found between treatments according to the Tukey test (P?0.05), the best CA values were given by the control treatment without promoter T0 and T1 300g/Ton with 3.18 weekly total.
