1. Hogs made more gain following three year old steers than when following yearling steers.
2. The younger the steer the fewer the pounds of feed for a pound of gain.
3. The loss, in shipping per head was greater when the cattle were fed sheaf oats enroute than when they were fed prairie hay.
4. The largest gain for feed consumed was made during the first thirty days when the steers were being put on full feed.
5. A longer feeding period was required to get yearling steers in a good marketable condition than was required for the two year old or the three year old steers.
6. More grain was required for a pound of gain during cold than moderate weather, indicating that a large percent of the feed was required for-maintaining body heat.
7. Deducting the gain made by steer No. 1; in the two year old lot of the first experiment, as it was much below the average for the two year old steers, only six pounds more gain was made by the three year olds than the two years old, and only nine pounds more was made by the two year olds than the year lings per head, showing that practically equal gains can be made with steers of different ages under the same conditions.
8.When mixed with oil-meal, one-tenth by weight, the three year old steers consumed an average of forty-fivebushels, the two year olds an average of forty bushels and the yearlings an average of thirty-four bushels of corn per head during the feeding period of 127 days.
9. With the three year old and the two year old lots a pound of pork was made for every five-pounds of beef produced, while with the yearling lots, one pound of pork was made for every nine pounds of beef. The production of pork being an important item in steer feeding operations and as experiments show that it is not profitable to grind corn for steers ( unless to increase the palatability)the combined gain of both cattle and hogs should be considered by the prospective feeder.
