Resumen

Introduction: Feeding in early childhood influences the establishment of adipose tissue, and therefore also in the development of various pathologies in adulthood. Objective: To evaluate the influence of the consumption of three sources of fatty acids on blood parameters and adipose tissue at an early age. Materials and methods: 76 Cobb 500 chicks randomly distributed in four treatments were used, who were fed for seven days with one of the four diets (T1: Basal diet; T2: DB +1.0% vegetable shortening partially hydrogenated; T3: DB +1.0% quinoa oil and DB +1.0% fish oil) until the seventh day of life. At the end, glucose, cholesterol, triglycerides and adipocyte size of the subcutaneous and visceral adipose tissue were evaluated. A completely randomized design with ANOVA considering 0.05 significance was applied and in the case of non-normally distributed variables, the non-parametric Kruskal-Wallis test was applied using the R-Studio program. Results: Significant differences were obtained with a decrease in glucose and cholesterol levels in animals supplemented with unsaturated oils (T3 and T4) compared to T2. Regarding the size of adipocytes, treatments T3 and T4 promoted a hyperplastic formation of adipocytes, differing significantly from T2, which promoted hypertrophy in these cells, this response was similar in both subcutaneous deposits. Conclusions: The consumption of quinoa oil and fish oil promote the formation of healthy adipose tissue, in addition to reducing glucose and cholesterol levels. In contrast, the consumption of vegetable shortening favors the hypertrophy of large adipocytes and increases the biochemical parameters evaluated.
