The current work aimed to study the effect of feeding Friesian calves
protected fat and protein diets on blood biochemical parameters using 18 newborn
Friesian calves up to 8 months of age in 3 dietary treatment groups. The 1⁵¹ group (C)
was fed untreated concentrate feed mixture (CFM), the 2nd was fed the control diet in
which 5% of CFM was replaced by protected fat (PF) and the 3~ was fed CFM treated
with 1 % formaldehyde (protected protein, PP). Results indicated that white and red
blood cells counts increased in PF and PP than C group. Frequency distribution of
lymphocytes increased (P groups. However, granulocytes did not differ significantly among groups.
Concentration of hemoglobin and PCV % increased (P group.
