The aim of this study was to determine the effect of a commercial mixture of essential oils (Mix–Oil®) on the productive parameters of Cobb 500 broilers. The work was carried out in a 40 m2 shed located in the Chongón parish, Guayas, Ecuador. In total, 400 male broiler chickens were placed in 40 polyethylene cages with a population density of 10 chickens.m-2. The supplementation of the commercial essential oil mixture Mix–Oil® in the water was compared against a treatment without application, distributed in two groups at random. Feed consumption, weight gain, feed conversion, water consumption, morbidity and mortality were evaluated. Supplementation with essential oils did not affect feed consumption; however, there was a tendency to generate lower body weight and lower weight gain in the initial stages of the productive cycle. The Mix–Oil® essential oil blend reduced morbidity during the growing stage and improved feed conversion (1.70), weekly weight gain (852 g.bird-1) and reduced water consumption during the finishing period of Cobb 500 chickens.

The effect of three sources of lipids in the diet of fattening turkeys from the Hybrid Converter line on growth, carcass weight and blood metabolites were evaluated. A total of 90 43-day-old male turkeys were randomly distributed into 3 treatments, with 5 repetitions and 6 birds per group. The turkeys received isonutritional diets supplemented with Cajamarca Creole lard (MCCC), soybean oil (AS) or palm oil (AP). Turkeys aged 43 to 70 days with MCCC and AP had better body weight gain, lower feed consumption and better feed conversion (p<0.05) than those with the AS treatment; However, there were no differences between treatments during the finishing phase (71-98 days) nor in the total fattening period (43-98 days). The carcass weight in MCCC and AS was greater than in AP, in addition, they reduced (p<0.05) the relative weight of the liver and the percentage of abdominal fat compared to AP. Triglycerides and total cholesterol in blood were lower (p<0.05) in AS and MCCC than in AP, likewise, MCCC decreased (p<0.05) the malondialdehyde content in blood. It is concluded that MCCC in fattening turkeys from 43 to 98 days of age can replace AS and AP in the diet, since it does not generate negative effects or a decrease in the evaluated indicators.
