Effect of Diet Supplementation with Combinations of Soybean and Linseed Oils on Milk Production and Fatty Acid Profile in Lactating Dairy Ewes
Antonacci, Liliana Elisabet; Busetti, Margarita Rosa; Rodríguez, María Alejandra; Cano, Adriana Virginia; Gagliostro, Gerardo Antonio (2018-02)Thirty-six Pampinta ewes were used in a completely randomized design to examine the effectiveness of soybean (SO) and linseed (LO) oils to reduce the concentration of the atherogenic fatty acids (FA) of milk (C12:0 to ... -
Effects of feeding combinations of soybean and linseed oils on productive performance and milk fatty acid profile in grazing dairy cows
Antonacci, Liliana; Gagliostro, Gerardo Antonio; Cano, Adriana Virginia; Bernal, Claudio Adrián (2017)Thirty-six grazing dairy cows were used to determine the effect of combinations of soybean (SO), and linseed (LO) oils on milk production, composition and milk fatty acid (FA) profile. Treatments were a basal control diet ... -
Effects of supplementation with increasing levels of energy concentrate on the productive response and ruminal digestion of dairy cows grazing lucerne pasture
Salado, Eloy Eduardo; Bretschneider, Gustavo; Cuatrin, Alejandra; Gagliostro, Gerardo Antonio (Scientific Research, 2018-11)The aim of the study was to determine the effect of three levels of energy concentrate intake on dry matter (DM) and energy intake, milk yield and composition, rumen environment and pasture neutral detergent fiber (NDF) ... -
Improving concentration of healthy fatty acids in milk, cheese and yogurt by adding a blend of soybean and fish oils to the ration of confined dairy cows
Gagliostro, Gerardo Antonio; Antonacci, Liliana Elisabet; Perez, Carolina Daiana; Rossetti, Luciana; Carabajal, Augusto (2020-01-18)Compared to pasture based sistems, milk produced in confined dairy systems is characterized by a high saturated fat (SF) content with a lower concentration of healthy fatty acids (FA) such as vaccenic (VA, trans-11C18:1), ... -
Improving the Quality of Milk Fatty Acid in Dairy Cows Supplemented with Soybean Oil and DHA-Micro Algae in a Confined Production System
Gagliostro, Gerardo Antonio; Antonacci, Liliana Elisabet; Perez, Carolina Daiana; Rossetti, Luciana; Carabajal, Augusto (2018-09-10)The objective was to reduce saturated fatty acids (SFA) and increase conjugated linoleic acid (CLA, cis- 9, trans -11 C18:2), α-linolenic (cis- 9, cis- 12, cis- 15 C18:3) and docosahexaenoic (DHA, C22:6) contents in milk ... -
Influencia de la suplementación con diferentes combinaciones de aceites sobre el perfil de ácidos grasos de la leche ovina = Influence of supplementation with different blends of oils on the fatty acid profile of sheep milk
Antonacci, Liliana; Cano, Adriana Virginia; Busetti, Margarita Rosa; Gagliostro, Gerardo Antonio (2016)La composición en ácidos grasos (AG) de la leche ovina es relevante en cuanto al valor saludable y puede ser mejorado a través del aporte suplementario de aceites vegetales poliinsaturados (AVPI). Los promisorios efectos ... -
