| description | The effect of supplementation with food rich in fatty acids on bovine milk performance and composition was evaluated. We worked with 15 Holstein cows, multiparous, on the second third of lactation. The animals were divided into control group, group 1 and group 2. We formulated three diets containing 16% crude protein and 1,73 Mcal ENL, and set 7 days for habituation and 83 for trial. We evaluated production (kg), fat (%), protein (%), non-fat solids, lactose (%) and density (g/ml) using the integral Lactoscan® milk analyzer. The diets consist of a staple food and the supplement to try that was added in amounts according to the maximum participation for ruminants. The staple food were alfalfa meal, rice flour, wheat bran, molasses and mineral premix, and the supplements to try were soybean meal and protected fat. We used a completely randomized experimental design and compared the data with the repeated measures ANOVA in R (v. i386). The results show that milk production increased significantly (P =< 0.05) after supplementation wuth soybean meal and fat protected reached in the control group. Although it is possible to increase production (kg/ day), the milk composition parameters did not improve, possibly due to the metabolic abnormality that may occur after ruminal fermentation of fats, and the alteration of the fatty acids mammary synthesis.

Keywo Se evaluó el efecto de la suplementación con alimentos ricos en ácidos grasos sobre los parámetros productivos y composicionales de la leche bovina, se trabajó con 15 vacas raza Holstein, multíparas, que cursaban el segundo tercio de lactancia. Los animales se dividieron en grupo control, grupo 1 y grupo 2, se formularon tres dietas con contenidos de proteína cruda del 16% y 1,73 Mcal ENL, se fijaron 7 días de acostumbramiento y 83 días de ensayo, se evaluó producción (kg), grasa (%), proteína (%), sólidos no grasos, lactosa (%) y densidad (g/ml), mediante el analizador integral de leches Lactoscan®. Las dietas están compuestas por un alimento base y por el suplemento a probar, que se agregó en cantidades de acuerdo con su participación máxima para rumiantes, los alimentos base fueron harina de alfalfa, harina de arroz, salvado de trigo, melaza y premezcla mineral, y los suplementos a probar fueron torta de soya y grasa protegida. Se utilizó un diseño completamente al azar, y los datos se compararon aplicando un ANOVA de medidas repetidas con R (v. i386). Los resultados revelan que la producción de leche aumentó significativamente (p≤0.05) tras la suplementación con torta de soya y grasa protegida, frente a la que se alcanzó en el grupo control. En conclusión, es posible incrementar la producción (kg/día), sin embargo, no mejoraron los parámetros composicionales de la leche, posiblemente, como consecuencia de la alteración metabólica que pudiese presentarse tras la fermentación ruminal de las grasas y la alteración de la síntesis mamaria de los ácidos grasos.
