The effects of physical forms of corn and forage source on growth performance, blood parameters and ruminal fermentation of Holstein calves

This investigation's purpose was the evaluation effects of physical forms corn and forage sources on growth performance, blood parameters, ruminal fermentation Holstein calves. Forty-eight calves (38.2 ± 1.2 kg BW) were used in a completely randomized design with 4 treatments 12 replications for 65 days. The were: 1) Basal diet + mashed form wheat straw (MCWS), 2) flacked (FCWS), 3) corn+ Sugarcane bagasse (MCSB) 4) sugarcane (FCSB). Final body weight daily gain affected significantly by (F) factor whereas no effect from C (corn forms) C×F interaction observed. Skeletal parameters not C, F, F×C factors. trial factors did affect triglyceride, urea BHBA levels. Glucose level F At 30 60 days, fed FCWS had highest glucose. Also, FCSB presented higher at Acetic acid interaction. Calves MCWS maximum concentration acetic acid. propionic Valeric While valeric differences observed
