Objective: To associate the levels of fatty acids in serum with anthropometric markers. Methods: A total of 48 subjects were evaluated by quantifying their relative percentages of serum free and esterified fatty acids (EFAs) by gas chromatography. Measures including body mass index (BMI), body fat percentage (BF%), waist circumference (WC) and waist-hip ratio (WHR) were used to characterize anthropometric measurements.

This work analyzed the viability of organic milk with the conventional production system, zootechnically and economically, using benchmarking. The organic farm had better results. Property A had the best yields in terms of the number of lactating cows (53.60 animals), number of cows per hectare (2.14 animals/ha), production total daily milk (1220L/day) and milk production per area (48, L/ha/day), also ranked second in milk production per lactating cow (22.16 L/day). Has positive values both per liter of milk (R$ 0,20 L/day) and per year (R$ 89.060,00/year).
