Abstract:
A feeding trial of 120 days was conducted in female crossbred calves to study the effect of different levels of dietary degradable protein on blood biochemical parameters. Eighteen weaned crossbred calves of six to nine months of age were selected from ULF & FRDS, Mannuthy and randomly allotted to three dietary treatments (CP 20%, TDN 70%) varying in degradable protein levels: Control- 65%; T₁ -55%; T₂-45%, respectively of total CP. The experimental calves were fed as per ICAR standards (ICAR, 2013). The blood biochemical parameters like, Hb, RBC, WBC, PLT, HCT, Lymphocytes, Monocytes, MPV, creatinine, serum calcium, phosphorus, zinc, copper, magnesium were analysed at the end of feeding trial. The observed values were similar between the treatments groups for all blood parameters and within the normal range opined for species. Therefore, it was concluded that feeding of concentrate mixtures (20% CP and 70% TDN) containing rumen degradable protein from 45-65% as percent of total CP had no adverse effects on blood biochemical parameters and health of crossbred calves.
