Last year at the Livestock Feeders' Day, results of experiments
were given on the use of mustard seed oil meal as a protein supplement
for fattening pigs on alfalfa pasture. The results showed that mustard
seed oil meal was an excellent protein feed when mixed with tankage
and other protein supplements and self-fed free choice. Generally
the gains were as cheap or cheaper than where tankage alone was fed
and the daily gain were somewhat more rapid with a lower feed consumption.
In the tests reported last year the mustard seed oil meal made up
as much as 50 percent of the protein mixtures with tankage in some
of the lots and at this level proved to be entirely palatable. The results
of feeding it in such large proportions were so satisfactory that
it was desired to ascertain whether it were possible to increase further
the amount of mustard seed meal in the mixture with tankage and
still get good results. Consequently two lots of pigs were fed this past
summer with an increased percentage of the mustard seed oil meal.
