Age at First Gestation in Beef Heifers Affects Fetal and Postnatal Growth, Glucose Metabolism and IGF1 Concentration
(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 = ... -
Efecto de la vacunación contra el virus de la fiebre aftosa sobre la pérdida de preñez en un rodeo de bovinos para carne
(Ediciones INTA, 2020-12)Se realizó un estudio para evaluar el efecto de la vacunación contra el virus de la fiebre aftosa (FA), aplicada durante el periodo embrionario, sobre la pérdida de preñez en un rodeo de vacas Angus que habían sido inseminadas ... -
Efectos de la inyección de cobre en vacas Angus al final de la gestación sobre el crecimiento fetal y posnatal de sus crías
(Ediciones INTA, 2021-12)Para determinar si la inyección de Cu durante el último tercio de gestación puede afectar el crecimiento fetal y posnatal de la progenie, se utilizaron 70 vacas Angus con 219 ± 15 días de gestación y se asignaron al azar ... -
Effect of Protein Restriction During Mid-to Late Gestation of Beef Cows on Female Offspring Fertility, Lactation Performance and Calves Development
(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
(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
(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. ... -
Effects of inorganic copper injection in beef cows at late gestation on fetal and postnatal growth, hematology and immune function of their progeny
(Elsevier, 2021-10)To determine if Cu injection during late gestation can affect fetal and postnatal growth, hematology and immune function of progeny, 70 multiparous pregnant Angus cows, at 219 ± 15 d of gestation, were ranked by BW and BCS ... -
Late-gestation protein restriction negatively impacts muscle growth and glucose regulation in steer progeny
(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, ... -
Manejo de los ovinos durante la gestación
(Estación Experimental Agropecuaria Balcarce, INTA, 2022-03)El período de parición suele ser el momento más crítico para cualquier sistema de producción animal, pero en ovinos es especialmente importante porque la mortalidad perinatal puede llegar a ser muy elevada, ocasionando ... -
The degree of maternal nutrient restriction during late gestation influences the growth and endocrine profiles of offspring from beef cows
(CSIRO, 2021)Context: Cow–calf operations in Argentina are managed under extensive grazing condition and the quality of forages is often poor during the second half of gestation. The severity of nutrient restriction in bovine gestation, ... -
The influence of protein restriction during mid- to late gestation on beef offspring growth, carcass characteristic and meat quality
(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 ...
