Efecto de un anabolizante de liberación lenta sobre el engorde de toros suplementados y no suplementados, pertenecientes a la finca MAGASA, en la parroquia Torata, El Oro.

Abstract

The present project was carried out at the MAGASA ranch, located in the parish of Torata, in the province of El Oro. The experimental work was divided into four treatments, where each treatment had 10 bulls from 1.5 to 2 years old. Additionally, they had an average initial weight range of 388 kg. The treatments were formed by two factors, the type of feeding and the use or absence of anabolic in the animal, so that T1, were bulls stabled with anabolic, T2, bulls stabled without anabolic, T3, bulls in grazing with anabolic and T4, bulls in grazing without anabolic. The objective of the work was to evaluate if there was an effect of the anabolic on the weight gain of the bulls, being the result of the statistical analysis that determined that there was no significant difference to attribute the weight gain to the use of the anabolic. Within the average weight gains in kg up to 45 days of the experiment, the T2 group was the one that presented the best weight gain with 30.6 kg, followed by T1 that obtained a gain of 29.3 kg in relation to the initial weight. On the other hand, the groups with grazing type feeding presented a very small weight gain, resulting in T4 with a gain of only 5.5 kg, while T3 presented an average weight loss of 1.6 kg in relation to its initial weight.
