The objective of the study was to evaluate the effect of Cocarboxylase (PPT) on the productive parameters, intestinal histomorphometry and liver histopathology in broiler chickens with 7 days of age, fed with a diet with the inclusion of cocarboxylase (10ppm) and compare it against diets which use oils of comercial use (AV = Vegetable Oil, AA = Acidulated Oil) to meet the requirements of Metabolizable Energy (ME). 300 male BB day-old chickens were distributed under a completely randomized desing with 5 treatments, 6 repetitions per treatment and 10 birds per repetition. The normality and homoscedasticity of the quantitative variables (Productive Parameters and Intestinal Histomorphometry) were evaluated. The analysis of variance (ANOVA) was made for the productive parameters and the differences between means were carried out by Duncan's test; for the intestinal histomorphometry as well as liver histopathology, the Kruskall-Wallis test was used, considering a statistical difference of P <0.05. A significant difference was found in the productive behavior between the groups, where T3 and T5 were higher (P <0.05) in Total weight gain, with T2 being the treatment that had the lowest performance (P <0.05). In regard to the data obtained for food consumption, it was higher in treatments T1 and T5 (P <0.05). For the Feed Conversion Index, there was no differences between treatments T1, T3, T4 and T2 being the one that obtained the worst feed conversion: 0.87 (P <0.05). The villi height measurement was longest in T1 while in T2 it was the shortest (P <0.05). In crypt depth, T1 and T3 were higher (P <0.05) compared to the other treatments. The ratio in treatment T1 was higher (P <0.05) with respect to the other treatments. Regarding Hepatic Histopathology, different types of lesions were found, T2 was the most affected treatment with the highest ranges for each specific lesion (P <0.05), while T3 and T4 were the least affected (P <0.05). It is concluded that the diets of pre-start chickens by the inclusion of PPT, responded positively in the productive parameters and a benefit on liver function, managing to reduce the Degenerative Processes caused by the addition of oils in the diet (AV and AA).
