Abstract

Weighing steers three consecutive days at the beginning and end of the trial reduced variation and increased the probability of detecting a difference in daily gain and gain/protein ratios between treatments when compared to a standard weighing method (once at the beginning and once at the end of the trial). Regressing 1 initial, 1 final and 11 weekly weights also decreased variation and increased the probability of detecting treatment differences compared to the standard method, but was more variable than using three weights at the beginning and end of the trial.

Young, growing steers and lambs supplemented with natural protein sources gained significantly faster than those fed urea. The relative values of blood meal (BM) compared with soybean meal (SBM) for the lamb and steer trials were 252% and 281 % respectively.
