Age at First Gestation in Beef Heifers Affects Fetal and Postnatal Growth, Glucose Metabolism and IGF1 Concentration
Lopez Valiente, Sebastian; Rodriguez, Alejandro Martin; Long, Nathan M.; Quintans, Graciela I.; Miccoli, Florencia Estefanía; Lacau Mengido, Isabel M.; Maresca, Sebastian (MDPI, 2021-11)This study aimed to determine the effects of age at first gestation on offspring growth performance, glucose metabolism, and IGF1 concentration. Heifers impregnated by AI from a single bull at 15 months of age (15 M, n = ... -
Effect of Protein Restriction During Mid-to Late Gestation of Beef Cows on Female Offspring Fertility, Lactation Performance and Calves Development
Lopez Valiente, Sebastian; Maresca, Sebastian; Rodriguez, Alejandro Martin; Long, Nathan M.; Quintans, Graciela I.; Palladino, Rafael Alejandro (E-Cronicon, 2019-12)Cow calf operation in Argentina are managed under extensive grazing condition and the quality of forages is often poor during second half of gestation. Protein restriction in bovine gestation affects production traits in ... -
Effect of protein restriction of Angus cows during late gestation: Subsequent reproductive performance and milk yield
Lopez Valiente, Sebastian; Maresca, Sebastian; Rodriguez, Alejandro Martin; Palladino, Rafael Alejandro; Lacau Mengido, Isabel M.; Long, Nathan M.; Quintans, Graciela I. (2018-06)The effect of level of CP fed during late gestation on reproductive performance and milk production was studied in multiparous cows. Sixty-eight pregnant Angus cows were used. At 121 d prepartum, cows were blocked by BW ... -
Effect of protein restriction of bovine dams during late gestation on offspring postnatal growth, glucose-insulin metabolism and IGF-1 concentration
Maresca, Sebastian; Lopez Valiente, Sebastian; Rodriguez, Alejandro Martin; Long, Nathan M.; Pavan, Enrique; Quintans, Graciela I. (2018-06)The objective of this study was determine whether the amount of protein provided to cows during late gestation would affect postnatal growth and lead to changes on glucose, insulin and insulin-like growth factor concentrations. ... -
Late-gestation protein restriction negatively impacts muscle growth and glucose regulation in steer progeny
Maresca, Sebastian; Lopez Valiente, Sebastian; Rodriguez, Alejandro Martin; Pavan, Enrique; Quintans, Graciela I.; Long, Nathan M. (Elsevier, 2019)The objective of this study was to determine whether the amount of protein provided to cows during late gestation would affect postnatal growth and lead to changes in glucose and insulin concentrations. At 129 d of gestation, ... -
The influence of protein restriction during mid- to late gestation on beef offspring growth, carcass characteristic and meat quality
Maresca, Sebastian; Lopez Valiente, Sebastian; Rodriguez, Alejandro Martin; Testa, Maria Laura; Long, Nathan M.; Quintans, Graciela I.; Pavan, Enrique (Elsevier, 2019-07)The objective of this study was to determine whether crude protein intake during the last three months of gestation affects growth performance, carcass characteristics and meat quality of steer progeny. At 134 ± 14 d of ...
