Exploratory study of hematological values in Holstein-Friesian crossbreed calves, during their first six months of life | [Estudio exploratorio de valores hematológicos en terneras Holstein Frisian mestizas, durante los primeros seis meses de vida]
Age-related changes in hematological values occur in almost all mammalian species, and published studies that include repeated measurements of hematological parameters in calves during the first months of life are limited. The objective of the present investigation was to determine the hematological...
