580 EXPERIMENT STATION RECORD. 



If lambs are sold in the summer at the age of 3 or 4 months it is 

 profitable to feed grain before weaning*. If they are sold in the fall 

 when about 7 months old it will pay to feed grain both before and after 

 weaning. If they are sold at 10 months old, after being fattened for 

 2 or 3 months during the winter, grain feeding before or after weaning 

 has no appreciable influence on the profits. 



Lambs fed grain from birth are fit for market at any time and 

 advantage may be taken of favorable prices. In the author's experi- 

 ence during several years the most profitable time to sell lambs is 

 before weaning, and in order that the greatest profit may be realized 

 he has found it best to feed grain from birth. 



Corn vs. corn meal for hogs, W. A. Henry ( Wisconsin Sta. JRpt. 

 1896, pp. 10-16). — Two tests were made to compare the relative value of 

 whole corn and corn meal. The first test was made with 2 lots of 9 

 pigs about 15 months old. Each lot contained 5 pure-bred Poland 

 Chinas and 4 Berkshire-Poland Chinas. Five were sows and the 

 remainder barrows. During the summer preceding the trial, the pigs 

 had been kept on pasture. They were fed corn and shorts for a short 

 time previous to the beginning of the test proper, which lasted 10 

 weeks. Lot 1 was fed shelled corn and shorts and lot 2 corn meal and 

 shorts. The corn used was 2 years old and contained 12.16 per cent 

 of water. It was fed dry. The corn and shorts were mixed with 

 water to a thick mush before feeding. Lot 1 at the beginning of the 

 test weighed 3,190 lbs. and gained 1,235 lbs. Lot 2 weighed 3,113 lbs. 

 at the beginning of the test and gained 1,348 lbs. Lot 1 consumed 3.96 

 lbs. of shelled corn and 0.47 lb. of shorts per pound of gain and lot 2 

 4.3 lbs. of corn meal and 0.51 lb. of shorts. 



The second trial was made with 2 lots of 10 pigs each. Lot 1 was 

 made up of 4 pure bred Berkshires, 4 Berkshire-Poland Chinas, and 2 

 grade Poland Chinas. Four of the pigs in this lot were sows and the 

 others barrows. Lot 2 was made up of 4 Berkshires and 6 Berkshire- 

 Poland Chinas; 5 were sows and 5 barrows. All the pigs were about 6 

 months old at the beginning of the test. They had previously been 

 fed corn meal and shorts. During the trial the rations were similar to 

 those fed in the first trial. Some of the pigs had the run of a rape 

 field also. The test lasted 10 weeks. Lot 1 weighed 2,254 lbs. and lot 

 2, 2,232 lbs. at the beginning. The gain of the respective lots was 789 

 lbs. and 1,076 lbs. Lot 1 consumed 4.22 lbs. of shelled corn and 0.65 

 lb. of shorts per lb. of gain; and lot 2,5.02 lbs. of corn meal and 0.89 lb. 

 of shorts. The author points out that, in the first trial with hogs in thin 

 fiesh at the beginning, 8 per cent of corn was saved by grinding. In 

 the second trial, with light hogs rather fat at the beginning, 17.6 per 

 cent of corn was saved by grinding. Considering the larger saving of 

 17.6 per cent, the author calculates the amount saved by grinding with 

 corn at different prices to be as follows: With corn at 28, 35, and 42 cts. 

 per bushel, the grain saved by grinding was worth 4.9, 6.1, and 7.4 cts., 

 respectively.
