the milk supplied. Dorset ewes are recommended for this purpose, since they 

 breed early, ai-e prolific, and give large quantities of milk rich in fat." 



Exercise v. confinement in -winter for young wethers, G. C. Humphrey 

 and F. Kleinheinz {Wisconsin Sta. Rpt. 1905, pp. 62-C)Ji). — In the test reported, 

 which covered 14 weeks, 14 lambs given outdoor exercise made an average 

 weekly gain of 0.94 lb. per head and required 7.07 lbs. of grain and 27.02 lbs. 

 of coarse fodder per pound of gain. In the case of a similar lot fed on the 

 second floor of the sheep barn and given no exercise the gain was 1.04 lbs. per 

 head per week, the grain eaten per pound of gain O.tJO lbs., and the coarse fod- 

 der 25.57 lbs. The cost of feed per pound of gain in the 2 cases was 12.7 and 

 12 cts., respectively. Both lots were fed similar rations of mixed hay, mangels, 

 and corn, oats, and bran 1:2:1. 



Summarizing this and earlier tests (E. S. R., 16, p. 807), the authors state 

 that the average weekly gain per lamb with exercise has been 1.2 lbs. and 

 without exercise 1.3 lbs., and the cost of gain in the 2 cases 12 and 11 cts. 



" The results of these 3 trials lead one to believe that for feeding growing 

 wethers, close confinement in pens which are dry, with fresh air and light, is equal 

 to, if not somewhat better, than allowing plenty of exercise. It is believed 

 that there is much space in the farm buildings throughout the State which could 

 be utilized for feeding a greater or less number of wethers. No better class 

 of stock can be recommended for converting farm grains and roughage into 

 cash and fertilizers than sheep. The farmer who has feed and unoccupied space 

 in barn driveways, emptied mows, or stair lofts, can utilize the same to a good 

 advantage by feeding sheep." 



The value of soy beans in grain rations for lambs, G. C. Humphrey and 

 F. Kleinheinz (Wisconsin Sta. Rpt. 1905, pp. 65-GS). — Continuing earlier work 

 (E. S. R., 10, p. 807), a ration of soy beans and shelled corn 1 : 1 was compared 

 with a similar mixture of oats and shelled corn. 



The 9 lambs fed the soy-bean ration made a total gain of 119 lbs. during the 

 12 weeks of the test as compared with 71 lbs. in the case of the corn and oats 

 ration. The grain eaten per pound of gain in the 2 cases was 6.35 and 10.02 

 lbs., respectively, and the coarse fodder 10.51 and 16.65 lbs. The lambs fed 

 soy beans produced 95.1 lbs. of wool and those fed oats 81.3 lbs. 



From this and earlier work the authors conclude " that soy beans are an 

 economical supplement to corn for gains with sheep both in body v>'eight and 

 wool production. The increase in wool produced was 13.8 lbs., which sold for 

 30 cts. per ])ound, increasing the profits by $4.14." 



The feeding stuffs used were analyzed. 



Summary of pig feeding experiments, F. B. Linfield (Vtah Sfa. Bill. 9.), 

 pp. 27-62). — Feeding tests with pigs are reported and general deductions are 

 drawn from tlie investigations which have been carried on since 1890 at the 

 station. 



In continuation of earlier work (E. S. R., 10, p. 980) the value of dairy by- 

 products for fattening was studied. In a test made with 2 lots of 3 pigs each 

 and 1 lot of 4 pigs the average daily gain in 7(i days on grain alone was 0.67 

 lb. per head ; on grain and slciin milk 1 : 10, 1.43 lbs., and on grain and skim 

 milk 1 : 5, 1.62 lbs. 



In the second test, which covered 87 days, 8 lots of 3 pigs each were used 

 and skim milk or whey alone, grain alone, and grain and skim milk or whey in 

 large and small amounts were tested. Three lots were fed in pens, the others 

 on pasture. The gain on pasture ranged from 0.67 lb. i)er head on skim milk 

 only to 1.25 lbs. on a full ration of grain and skim milk. In pens the gain 

 ranged fi'om 0.75 lb. on grain alone to 1.35 lbs. on a full ration of grain and 

 skim milk.
