Effects of Feeding Calcium Salts from a Mixture of Linseed and Fish Oil on Productive Response, Metabolic Status, and Reproductive Parameters in Early-Lactation Dairy Cows
Roskopf Perez, Pablo Matías; Cuatrin, Alejandra; Stangaferro, Matías Luis; Storani, Gino; Angeli, Emmanuel; Hein, Gustavo Juan; Salado, Eloy Eduardo (MDPI, 2025-07)This study evaluated the effects of supplementing early-lactation Holstein cows with rumen-protected omega-3 fatty acids (calcium salts) on productive and reproductive performance. Thirty-six multiparous cows were randomly ... -
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) ... -
Feeding Calcium Salts of Linseed Oil on Metabolic Status and Reproductive Traits in Grazing Dairy Cows
Iorio, Jesica Daniela; Moreno González, Yaliska; Olmeda, Maria Florencia; Curletto, Dino; Scandolo Lucini, Daniel Edgardo; Maciel, Martin Guillermo; Palladino, Rafael Alejandro; Giuliodori, Mauricio Javier; Salado, Eloy Eduardo (Scientific Research Publishing, 2024-07)This experiment aimed to evaluate the effect of calcium salts of linseed oil (rich in alpha-linolenic acid (ALA, C18:3n-3) on metabolic and reproductive traits in high-producing dairy cows under grazing. Thirty-six Holstein ... -
Feeding Calcium Salts of Linseed Oil on Productive Performance and Milk Fatty Acid Profile in Grazing Dairy Cows
Moreno González, Yaliska; Iorio, Jesica; Olmeda, María Florencia; Curletto, Dino; Scandolo Lucini, Daniel Edgardo; Maciel, Martin Guillermo; Cuatrin, Alejandra; Palladino, Rafael Alejandro; Perez, Carolina Daiana; Salado, Eloy Eduardo (Scientific Research Publishing, 2020-10)The objective of this study was to determine the effect of supplying calcium salts of linseed oil (Ca-FA) rich in omega-3 (α-linolenic acid) on the production and chemical composition of milk and its nutraceutical value ... -
Milk Yield and Composition and Pasture Ruminal Digestion in Grazing Dairy Cows Receiving Three Levels of Energy Concentrate Supplementation
Salado, Eloy Eduardo; Bretschneider, Gustavo; Cuatrin, Alejandra; Descalzo, Adriana Maria; Gagliostro, Gerardo Antonio (2017-10)The objective of the experiment was to determine the effect of feeding three levels (T3.5, T7.0 and T10.5) of energy concentrate (3.5, 7.0 and 10.5 kg cow-1 day-1) on total dry matter (DM) and energy intakes, milk yield ... -

Pérdidas de preñez en un rodeo de cría del norte de la provincia de Santa Fe = Pregnancy losses in a beef cattle herd in northern Santa Fe
Abdala, Alejandro Ariel; Maciel, Martin Guillermo; Salado, Eloy Eduardo; Aleman, R.; Scandolo Lucini, Daniel Edgardo (Asociación Argentina de Producción Animal, 2013-12)Se evaluó durante tres años consecutivos las pérdidas por abortos en un rodeo de cría bovino, libre de brucelosis y tuberculosis, con control de enfermedades venéreas y aplicación de vacunas contra enfermedades reproductivas. ... -
Productive response and reproductive performance of dairy cows subjected to different feeding systems
Salado, Eloy Eduardo; Maciel, Martin Guillermo; Bretschneider, Gustavo; Cuatrin, Alejandra; Gagliostro, Gerardo Antonio (Scientific Research Publishing, 2020-01)Fifty Holstein cows (2.6 ± 1.0 lactations) in early lactation (52.6 ± 16.4 days in milk) calved in autumn and producing 34.3 (±4.4) kg milk per cow∙day−1 were randomly assigned for 27 weeks to one of two treatments (feeding ... -
Productive Response of Dairy Cows Fed with Different Levels of Totally Mixed Ration and Pasture
Salado, Eloy Eduardo; Bretschneider, Gustavo; Cuatrin, Alejandra; Descalzo, Adriana Maria; Gagliostro, Gerardo Antonio (2018-07)Forty multiparous Holstein cows in early lactation (66 ± 19 days) were assigned to one of four treatments that consisted in different ratios of total mixed rations (TMR) and pasture at 100% TMR (T0), 75:25 (T1) 50:50 (T2) ...
