The objective of this study was to evaluate the fatty acid composition of butter from Holstein cows fed diets containing ground sunflower seeds or ground and pelleted sunflower seeds, with or without the addition of lignosulfonate. The butter was produced from milk collected from eight Holstein cows multiparous, with 100±62.6 days in milk, with a mean weight of 556±39.8 kg Body Weight (BW) and producing 15.6±0.12 kg of Milk/day. The cows were distributed in a double Latin square, with 4 periods of 21 days each, with 14 days for adaptation and seven days for data collection. Diets containing pelleted sunflower seeds altered the fatty acids profile of the butter, with an increase in the fatty acids 16:1n-11, 18:1trans and CLA18:2 c9 t11. However, decreased the amounts of fatty acids 18:0 and 20:0. The amounts of Saturated Fatty Acids (SFA) decreased, while the Polyunsaturated Fatty Acids (PUFA) and the amount of total Conjugated Linoleic Acid (CLA) increased with the pelleted diet. Thus, the use of diets with pelleted sunflower seeds is possible to obtain butter with desirable nutritional value in dairy products, which are beneficial for consumer health.
