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 ... -
The degree of maternal nutrient restriction during late gestation influences the growth and endocrine profiles of offspring from beef cows
Lopez Valiente, Sebastian; Rodriguez, Alejandro Martin; Long, Nathan M.; Lacau Mengido, Isabel M.; Maresca, Sebastian (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, ...
