Inclusión de Origanum vulgare deshidratado como promotor de crecimiento en cerdos de precebo.

Abstract

The present research was carried out in Sardinata Norte de Santander and aimed to evaluate the effect of including Oreganum vulgare dehydrated in the diet of pre-fattening pigs. Fourteen Duroc X Landrace breed pigs (males and females) were selected, weaned at 28 days of age, with an average initial weight of 7.30 ± 4.86 kg for females and 7.32 ± 4.18 kg for males, and randomly distributed in three treatments: T1, 0% oregano; T2, 4% dehydrated oregano; T3, 8% dehydrated oregano. The diets were supplied from day 28 of age until day 84, implementing a week of adaptation for the piglets. Productive parameters such as body weight, weight gain, daily feed intake, feed conversion ratio, survival, and zoometric measurements such as body length, thoracic perimeter, shoulder length, and ham length were evaluated. The results did not reflect significant differences (P0.05) for the productive parameters in the evaluated treatments. All animals accepted the food offered after the adaptation period, and there was no mortality in the piglets during the experimental period. The economic analysis showed a lower cost for treatment 1 (0% oregano), with an economic conversion rate (ECR) of $898,20, compared to T2, which obtained an ECR of $901,44 and T3, $952,66.. It is concluded that the inclusion of dehydrated oregano in the diet does not improve the productive parameters in pre-fattening pigs, however, it implies an additional cost.
