To determine effects of rations mainly formed by early or late-bloom cut hay from meadows fertilized by N and P2O5 or not fertilized, on the growth performance, 20 female Brown Swiss calves (6-12 m) were fed for 129 days. Average daily weight gain, feed per unit weight gain and total intake of meadow hay were better for hay from meadows fertilized with N and P2O5 as compared to hay from not fertilized meadow. Similarly these parameters were better for calves fed early bloom hay than for calves fed late bloom hay. Application of N and P2O5 fertilizers and early cutting stage for meadow hay is suggested for providing better growth performance and feed efficiency traits of the Brown Swiss calves.
