Fattening' range lambs, I*, p]. Carmichaei, {Ohio Stii. Hiil. 179, pi). 6<S-SS, 

 fif/s. .'/). — The rehitive value of eotton-seed meiil, linseed meal, and a commercial 

 stock feed as supplements to corn was studied with 4 lots of 40 wether lambs 

 each, the test covering IdM days. In every case the grain ration was supple- 

 mented by clover, blue-grass, and alfalfa hay. 



The daily gain on the corn ration was (».2'.»,S II). per head and on corn supple- 

 mented by other concentrated feed it ranged from ().."^02 Ih. on linseed meal to 

 0.312 Ih. on a commercial stock feed. The cost of a pound of gain on the corn 

 ration was 4.01 cts., on the ration with a connnercial stock feed 4.S0 cts., and on 

 cotton-see<l meal and linseed meal .">.14 and .").:!1 cts., respectively. One of the 

 lambs fed the commercial stock feed died during the test. Wiien the lots were 

 .slaughtered and dressed the shrinkage ranged from ."((i.o per cent with the 

 cotton-seed meal lot to n:-!.:") per cent with the corn lot. 



The manure from the 4 lots was collected and its value estimated, that ob- 

 tained from the lots fed t-otton-seed and linseed meal being the most valuable. 

 " The extra cost of the rations, however, more than equaled the increased value 

 of the manure." 



As pointed out by the author, the lot fed the connnercial stock feed made 

 slightly greater gains iit a lower cost than the other lots, and also shrank less 

 in shii)ping and yielded a higher percentage of dressed weight than any of the 

 lots except that fed the corn ration without additional concentrated feed. The 

 author notes, however, that the ditferences in gains between the H lots receiving 

 coucentrated feed in addition to corn were so small that it can not be said that 

 any of the rations jiossessed a decided superiority over the others. " It would 

 not be surprising if the same rations shcmld give oiiposite results in future 

 trials, and it is safe for us to consider that the rations tested are of practically 

 ('(jual viilue pound per pound for use in lamb feeding under the conditions of 

 this test." 



Crossbred lambs, (J. M. McKeowx (Af/r. (Uir.. A'. N. Walcx. IS (IDOl), Ao. .^. 

 pp. 156-li)8, pfix. ■)). — As regards the luimber of land is horn, average weight, etc., 

 the best results were obtained with a Lincoln-Merino cross in lamb-breeding 

 experiments at the Wagga Experimental Farm. 



Swine, J. J. Morton (Orange Hirer CoJoiui Dcpt. A(/r.. Ann. Hpt., 2 (1005-6), 

 pp. 5'i-62, pis. 2). — Brief statements are made regarding the pigs kept at the 

 Tweespruit Experimental Farm and a feeding test undertaken with reference 

 to the ])roduction of b.-icon hogs is reported. 



Four lots containing 4 large Yorkshire pigs each were used, and the rations 

 consisted of separator skim milk and maize meal, buttermilk and maize meal, 

 and skim milk and Katir corn meal in each case 3:1, and wheat nnddlings 

 (shari)s) and maize meal 1:2 mixed to a slop with water. In the 40 days of 

 the test the gain ranged from (;<).25 lbs. per bead on the wheat nnddlings and 

 maize meal to OS lbs. on skim nulk and maize meal. The gain was most cheaply 

 m.ade on the l.nst-mentioned ration and was most ex]»ensive on the Kafir corn 

 ration. The shrinkage in dressing averaged 20 \)vr c'ent of the live weight, 

 and when marketed "the meat gave entire satisfaction as to (piality and 

 tiavor " and was regarded as superior to impoi'ted bacon. 



In the author's opinion so good results would not have been obtained with 

 ordinary Kafir or unimproved pigs, "but even at a nuich lower rate of Increase 

 they afford a profitable means of disposal for a |)ortion of the mealie crop."
