gain was (MM.". Ih. per lioad per day, and the cost of a ixmiid of gain 5.7 fts. The 

 shoop us«>d in this test were hadly " loi-oed " and when received were liardly 

 strong enough to stand. They weiglied on an average 42.5 lbs. 



"'Locoed" sheep that had been treated with vermifuges fed during 123 days 

 gained as rapidly and made as economic gains as a band of healthy wethers, 

 r.eing small and thin, however, they would iiave to be fed at least twice as long 

 to get them re.ady for the market." 



Heavy (1.5 11..) and light (1 lb.) grain rations were compared with 100 

 wethers divid( d into 2 uniform lots. The grain consiht(>d of the mixture men- 

 tioned above and was supplemented by clover hay. On the heavier ration the 

 average daily gain in the <!5 days covered l)y the test was 0.208 lb. per head, and 

 on the lighter ration 0.2o2 11). pci- .lu ad, tiie cost of a iMiund of gain in the 2 

 cases iieing (!.5 and 7..'{ cts, and the grain eaten per pound of gain 1.81 and 2. 01

Experiments with Siiffolk and Lincoln crossbred sheep at Glen Innes 

 Experimental Farm (A(/r. Guz. A'. .S'. Wales. 11 (1906). .A"o. .3. pp. 236-238, 

 fi;/. 1). — The breeding tests were carried on by R. II. Gennys, who found that 

 the Lincoln-Merino cross produced heavier wool than the Suffolk-Merino. The 

 wool of all the crosses was nmch improved by the Merino blood. As mutton 

 sheep the Suffolk-AIerino crosses, both as lambs and as full-grown sheep, were 

 superior to the others. Sufficient data have not yet been accumulated regarding 

 the Kommey and Shropshire crosses for drawing deductions. 



Effect of covering the body on the distribution of fat, J. Bergoxie (Compt. 

 h'cml. .S'oe. Biol. [Paris], 60 (1006). Xo. 16, pp. 191, 7i?2).— Experiments with 

 lambs with one-half the body shorn at intervals of 8 days failed to show any 

 effect upon the formation of fat. Slight differences in the distribution of the 

 fat on the shorn and unshorn sides were noted. 



Pig feeding experiments, F. B. Linfield {Montana Hta. Bui. 51, pp. 39-o6) . — 

 In the first of the tests reported the relative efficiency of grain and alfalfa hay 

 and grain and roots with and without exercise was studied with 4 lots of 4 pigs 

 each, the test covering 80 days. The roots fed in this and other tests were 

 nearly always sugar beets. The average daily gain per pig on grain and hay 

 with exercise was 0.57 lb. and without exercise 0.42 lb., and on grain and roots 

 with exercise 0.G5 lb. and without exercise 0.30 lb. 



In the second test barley and bran alone and supplemented by skim milk and 

 Iiy clover hay were comjiared with .*> lots of 5 pigs each for 98 days. 



The third test was like the second excei)t that sugar beets as a supplement to 

 barley and bran were also included. This test covered 81 days and the 4 lots 

 contained 4 pigs each. Considering both tests the average gain on grain alone 

 was 0.92 lb., on grain and skim milk 1.37 lbs., and on grain and clover hay 1 lb. 

 per head per day. The corresponding gain on sugar beets was 1.09 lbs. 



In the third test the lots fed barley and bran and grain and clover hay were 

 not ready for market at the close of the test, so the feeding was continued for 

 17 days, the ration consisting of the grain mixture supplemented by roots and 

 skim milk. The average daily gain per head was 1.8 lbs. 



In the fourth test reported full rations of grain wet up with water and with 

 skim milk were compared with a one-fourth grain ration mixed with water, the 

 rations in eveiy case being supplemented by pasturage. Two of the lots con- 

 tained 3 pigs each and the remaining lot 2 pigs. The test covered 55 days. On 

 the full grain ration mixed with water the gain was 1.41 lbs. per head per day, 

 on the full grain ration with skim milk 1.70 lbs., and on the half grain ration 

 0.94 lb.
