Resumen

This study aimed to assess the effects of thermogenic oils (safflower and coconut oils) as a replacement for ractopamine in heavy pig diets. A total of 24 mix-breed barrows with an average weight of 98.70 ± 1.63 kg were distributed in a randomized block design with four treatments and six replicates. Treatments were as follows: basal diet, modified basal diet + 10 ppm ractopamine, basal diet + safflower oil, and basal diet + coconut oil. Animal performance, organ weights, meat quality, carcass traits, and economic viability were determined. Data were analyzed using Duncan's test at the 5% significance level. The safflower oil diet resulted in the highest carcass meat and ham weights, whereas the coconut oil diet provided the highest loin eye area and the lowest fat area, resulting in the highest meat/fat ratio. Analysis of economic viability indicators revealed that vegetable oil treatments differed significantly from other treatments in feed cost, feed cost per kilogram of live weight, economic viability index, and cost index, given that oil inclusion increased the price of diets. Supplementation of heavy pig diets with thermogenic oils is a viable alternative to enhance lean meat production, but its use depends on market availability and product price.
