Eighty-eight spring calving and 58 fall calving Hereford and Hereford × Angus cows were wIntered on dormant native tallgrass range to study the value of wheat middlings (WM) as a source of supplemental CP and energy. Supplements consisted of soybean meal (SBM, 40010 CP), SBM and WM (32% CP), WM and SBM (24% CP), and WM (16% CP). Each supplement was individually fed and provided .36 kg CP daily from November 5 to December 9, and .54 kg CP from December 10 to May 4 for spring calving cows. Fall calving cows were fed .36 kg CP daily from November 29 to December 9 and .54 kg from December 10 to March 15. Precalving weight changes for spring calving cows increased linearly (P |
