A method of feeding orphan lambs, W. E. Carroll (Utah Sta. Circ. S3 

 (1918), pp. 8, figs. 5). — A system of feeding motherless lambs, including the 

 description of a feeder for this purpose, is briefly outlined. 



A preliminary report on feeds for fattening pigs, J. S. Maloxe (Oklahoma 

 Sta. Bui. 120 (1918), pp. 7).— The results of two tests made to determine the 

 relative merits of tankage, peanut meal, and cottonseed meal as supplements 

 to Kafir corn, together with data secured in a comparison of corn, Kafir corn, 

 and darso as a fattening feed for pigs, are presented as a preliminary report. 



In the tests with the different protein supplements the four lots of pigs used 

 received the Kafir corn and the supplements through self-feeders. Three lots 

 were given each one of the supplements and the fourth was given all three of 

 them in addition to the Kafir corn. The results of the two tests were in favor 

 of tankage, the tankage lots having eaten more feed and made faster and more 

 economical gains and greater gains per pound of feed than those getting cotton- 

 seed meal or peanut meal. The lot having access to the three supplementary 

 feeds made as rapid gains bat ate more fei d per pound of gain and made less 

 profit than the tankage lot. 



In the comparison of corn, Kafir corn, and darso, tankage was fed with each 

 of these groins through self-feeders. The lot of pigs fed corn consumed 3.40 

 lbs., the one fed Kafir corn 3.7 lbs., and the lot fed darso 4.2.". lba of feed per 

 pound of gain. The results indicated also that when gnund and fed in self- 

 feeders Kafir and darso will prodoo pid gains and as '-' 1 pork as corn, 



and that more supplement is required for darso than for Kafir corn and less 

 for Kafir corn than for corn. 



Feeding swine during fall and winter. W. I„. ROBIBON (Jfo. Bui. Ohio SUu, 

 S (1918), No, It. pp. .'7*. 3). — The results of several feeding experi- 



ments are summarized in tables and briefly discussed. 



In tlie first experiment reported " each were fed for 10 weeks on corn 



alone and on corn and tank:: rn alone produced 9.06 Lb& gain per bushel, 



while with the addition of 5.5 lbs. of tankage the production of gain was 

 13.29 lbs with corn at $1.68 per bushel and tankage at $120 per ton. the 

 feed cost per pound of gain was 18.55 Cts. for e.>rn alone and 13. 78 ets. for 

 corn and tankage. 



In another test a bushel of corn fed alone produced 8.18 lbs. of gain, and 

 when fed with 168 lbs, of skim milk the gain was 21.82 lbs., each KM) lbs. of 

 skim milk replacing 54.91 lba of corn. In one instance corn alone resulted In 

 11.77 lbs. of gain per bushel, and corn and skim milk fed in equal quantities 

 by weight produced 16.52 lb& of gain. On the basis of skim milk at 50 cts. 

 and hogs at $16 per 100 lba the corn netted S2.3fi per bushel as against 51.88 

 when fed alone. 



In a < omparlson of ration - a alone and of corn and linseed-oil meal 5 : 1, 



1 lb. of oil meal replaced 1.52 lbs of corn, and the rate of irain with corn and 

 oil meal was 19 pel cenl higher than with corn alone. 



The results of a comparison of a ration of corn and wheat middlings with 

 one of corn and tankage showed thai pigs u-i] corn ami middlings, 1 : l. gained 

 24.4 per cenl less rapidly find required 9.5 per ..nt more feed per unit of gain 

 than those (ot] corn and tankage, 9: 1 



To determine the amount of supplement that should be fed with corn, rations 

 averaging 4.9, 10.8, and 1841 lbs, of corn to l lb. of tankage were compared 

 In n test in progress for 20 weeks The rate of gain was found to vary directly 

 with the amount of the tankage Slightly less bed per unit of gain was required 



" t 1 :.' medium ration than of either of the other two. and this ration also gave 

 ■ highest value of gains over COSl of feed.
