Hemato-biochemical and Endocrinological Changes during Late Pregnancy in Cows

During the course of gestation, hormonal, biochemical and hematological alterations take place for the care of the growing fetus and to prepare the mother for parturition. This study aims to determine hematological, biochemical, and hormonal alterations during late pregnancy. This study involved 10 Holstein Friesian (cross) cows which are in later stage of pregnancy and 10 non-pregnant Holstein Friesian (cross) cows of different cattle farms of Chattogram, Bangladesh Blood samples were collected from the tail vein and serum was tested to analyze various hematological, biochemical parameters and hormonal changes with commercially available kits. Statistically significant (P<0.05) observations are found in Hemoglobin (g/dl), Hematocrit (%), Mean Corpuscular Hemoglobin (MCH) level and platelet counts between pregnant and non-pregnant cows. However, only glucose was observed to be greater in pregnant cows among the biochemical parameters. Furthermore, estrogen altitude in pregnant cows was increased significantly (P<0.05) whereas progesterone was reduced non-significantly (P>0.05) in the later stage of pregnant cows. Conclusively, for the betterment of the cows with their infants, it is comprehensible to learn those parameters for the prevention of postpartum complications.
