FATTENING YEARLING STEERS - 1954 - 55
On October 15, 1954, four lots of 10 yearling steers each were placed in lots for fattening on corn silage and varying supplements. Lot I was fed 3.5 lbs. of a supplement similar to Purdue supplement - A per head daily. Lot II received 2 lbs. of soybean oilmeal, 2.5 lbs. of alfalfa hay, .2 lbs. of steamed bonemeal, and .07 lb. of trace mineralized salt per head daily. Lot III received the same ration as Lot II for the initial 60 days, the was given 4 lbs. per head day of ground barley and oats mixed 2:1 in addition. Lot IV was fed the same ration as lots II and III for 60 days, then the soybean oilmeal was reduced to 1½ lbs., and 1 lb. of the same grain mixture as used in lot III was added.
For the second consecutive year, purdue - A - like supplement gave less efficient gains than any other supplement used. Each 100 lbs. of beef produced in lot I required 3,336 lbs. of corn silage and 180 lbs. of supplement. Feed cost of lot I beef was given $25.70 per cwt. Lot II was second lowest in efficiency of gains. The feed cost of beef in lot II was $23.65 per cwt. That high cost of gains did not allow any profit except by virtue of the margin in selling price over purchase price. Lot III steers were the best finished steers at market at time and sold higher than any others. Silage consumption per 100 lbs. of beef averaged 2,749 lbs. in lot III. Total feed cost of 100 lbs. of beef in lot III was $22.15. Lot IV was the most economical in feed cost, averaging $21.22 per cwt. of beef produced. Lots III and IV which received grain in the ration during the final 90 days of the fattening period were the best finished of all the lots, yet the thinner steers of lot II chanced to sell 15 cents per hundred weight higher than lot IV steers.
The packers who purchased the steers gave the dressing percentages and carcass grades
as shown in Table VIII. Only 7 of the 10 steers in lot I were
fat enough for the butcher. The carcass grade bore out our observations as to relative
degree of finish in the 4 lots of steers. Only lot III steers were fat enough to grade
choice, lot IV was half choice and half good, lot II had 3 choice and 7 good, while lot I
had only 1 choice steer. The packers' reports mentioned the somewhat darker color of fat
in all steer as objectionable. The yellow fat probably can be traced to the high level of
corn silage in the ration.

|1Condition and covering was
satisfactory for grade choice. Graded good because of darker color.
2Some of this lot would have been graded prime except for darker color.
*Three lighter steers from Lot I were cut back by buyers and sold as feeders.
