silage and clover hay. The lambs relished the gluten feed and oats mixture 

 and gained a trifle more than those fed wheat bran and oats. 



In a comparison of cottonseed meal v. linseed meal for fattening western 

 lambs, 40 lambs were fed for 70 days a ration of 0.21 lb. of linseed meal, 1.12 

 lbs. of shelled corn, 2.75 lbs. of silage, and 0.83 lb. of hay, and another lot 

 of 40 lambs was fed 0.16 lb. of choice cottonseed meal, 1.16 lbs. shelled corn, 

 2.75 lbs. silage, and 0.85 lb. of hay per head daily. The lambs fed linseed 

 meal gained 0.365 lb. per head daily at a feed cost of 8.62 cts. per pound of 

 gain, and those fed cottonseed meal gained 0.37 lb. at a feed cost of 8.42 cts. 

 per pound of gain. 



Experiments with sheep, E. J. Riggs (Ohio Sta. Bui. 303 {1916), pp. 176, 

 177). — At the Washington County experiment farm, a comparison was made 

 during the winter of 1914-15 of linseed meal and cottonseed meal in equal 

 quantities as supplemental feeds for breeding ewes. No great differences were 

 found between the feeds. However, the lot on cottonseed meal maintained 

 their weight better and sheared 0.5 lb. of wool per head more than those fed 

 linseed meal. The ewes fed linseed meal produced lambs that were heavier 

 at birth than those fed cottonseed meal. At ten days of age and at the close 

 of the experiment the lambs from the cottonseed meal fed ewes were heavier 

 than the others. 



Forage crops [for hogs], F. C. Minkler (Neiv Jersey Stas. Rpt. 1915, pp. 

 67-73, pis. 2). — Continuing experiments already noted (E. S. R., 34, p. 172) 

 comparisons were made of different forage crops for swine. 



It was found that where the animals were given their choice of forage crops 

 brood sows nursing their young foraged quite as much on sweet clover as on 

 alfalfa. Rape alone or rape and sweet clover were equally as palatable as 

 alfalfa. Peas unaccompanied by oats or rape did not seem to attract the ani- 

 mals until they were more or less mature. It was noted that peas were more 

 palatable when grown In the same area with oats and clover. 



In case alfalfa is used as a forage with swine the area should be cut over 

 at least twice during the season in order to increase its palatability and re- 

 vitalize the plants. Light pasturage during the process of cutting alfalfa 

 seemed to produce no injury to the stand. 



Combination forage mixtures proved more useful and stable and produced 

 more pork per unit of area than single forage crops. Pasturing forage crops 

 early in the spring before the plants were 8 in. high proved to be an unsafe 

 practice. It was found expedient to shut the animals out of the forage crop 

 plats immediately following a heavy rain as a means of protection to the 

 plants, and further to avoid injury from rooting by the animals. Where the 

 combination mixture of oats, rape, peas, and clover was seeded and the areas 

 not cropped close enough to prevent some of the oats from maturing a catch 

 crop resulted and supplied palatable forage during the balance of the season. 



A plat of 2.3 acres of rye, oats, Canada field peas, and sweet clover with 

 grain supplement produced 781 lbs. of pork from May 11 to October 18 be- 

 sides providing maintenance for 10 mature hogs from July 1 to October 18. 

 A plat of 2.93 acres seeded to rye in the fall furnished green forage during 

 the early spring for 18 gilts. On June 7 this plat was seeded to rape, soy 

 beans, and sweet clover and provided maintenance for from 17 to 22 mature 

 sows from August 12 to October 20, a small amount of green corn being fed 

 as a supplement after October 1. An area of 4.76 acres of rye produced 

 1,270 lbs. of pork from April 20 to May 19, largely the result of young pigs 

 running with their dams. This plat was then seeded to corn, and from the 

 gleanings, after the corn was cut for silage with a corn harvesting machine, 

 30 shotes made a gain of 300 lbs. The yield of silage was about 11 tons per
