Two experiments are reported comparing linseed meal with soybean meal, combinations of linseed meal and urea, or a combination of several other protein-rich feeds. In previous studies, milk production has tended to be slightly lower in reversal-type experiments when either urea or linseed meal served as the only supplement, in comparison with soybean meal or corn distillers dried grains. In one experiment cows produced an average of 46.7lb of 4% fat-corrected milk (FCM) per day on a supplement of linseed meal plus urea, compared with 45.4lb on soybean meal plus linseed meal and 45.6lb on soybean meal as the only supplement. These values were not significantly different. In a second study the daily FCM production averaged 42.1lb on soybean meal, 41.3lb on a supplement of soybean meal plus linseed meal plus corn distillers grains, and 40.8lb on soybean meal plus linseed meal plus corn distillers grains plus corn gluten feed. The differences between these means were not significant. Likewise, there were no measurable differences in weight gains, or in general condition and health of the various groups of cows.
