"(1) Under the conditions existing in this ex{)erimcnt the lotreceiving a good qual- 

 ity of clover hay \vii,h a grain ration of whole corn rerinired less dry matter to i>roduce 

 a jtoiVnd of gain, made greater gains, ^vere in better flesh, and in general were fed 

 at a greater profit than the lots fed corn and bran, corn and wheat, or wheat and 

 (lil meal. 



" (2) Lots receiving roots in the ration required less dry matter to each pound of 

 gain, made greater gains, and drank less water than the other lots fed the same ration 

 without the roots. 



"(3) This experiment would seem to indicate that, when the conditions are similar 

 to those in this test, the feeding of wheat to fattening lambs is better practice than 

 selling at the prices prevailing during this experiment. 



" (4) This experiment indicates that lambs may be successfully fattened by means 

 of a S3lf-feed, but the gains made are i^roduced by a greater consumption of dry mat- 

 ter for a pound of gain, and are consequently less profitable than gains resulting 

 from feeding at regular intervals in the ordinary manner. 



" (.5) In this experiment the value of foods for fattening purposes seems to depend 

 more upon the supi)ly of available carbohydrates than upon the supply of protein. 



" (6) Cold temperatures were favorable to increased gains and warm temperatures 

 were very generally accompanied by decreased gains. 



*' (7) Less drj matter was required t6 produce a pound of gain in cold than in warm 

 temperatures." 



G-rain feeding lambs for market, J. A. Craig ( Wisconsin Sta. Bui. 

 41, pj). 21), — Three separate experiments are described in feeding grain 

 to lambs before weaning, between weaning and fattening, and during 

 the fattening period only. In the first two experiments there Avere 2 

 lots of lambs, one lot being fed grain from before weaning until the 

 elose of the fattening period, and the other lot receiving no grain until 

 the fattening period. In the third trial there were 3 lots, the grain 

 feeding commencing with one lot before weaning, with another after 

 weaning, and with the third during the fattening period. 



The^"rain fed before weaning was corn meal, wheat bran, and linseed 

 meal; between weaning and fattening, corn and linseed meal, or. whole 

 oats; and during fattening, corn, oats, and linseed meal, or corn and 

 linseed meal, or corn and oats. Between weaning and fattening the 

 lambs were all pastured. 



The feeding period before weaning was 10 to 12 weeks; between 

 weaning and fattening, 14 to 19 weeks, and the fattening period, l^to 14 

 weeks. At the end of each period the lambs were valued by a local 

 butcher. In estimating the relative cost, the gain only is considered 

 and no account take^a of the pasturage. The first experiment has been 

 already reported in the Annual Report of the station for 1892 (E. S. 

 K., 5, p. 503). The results of the 3 experiments are tabulated in the 

 bulletin, and are concisely stated in the following summary: 



" (I) The feeding of grain before weaning produced an average of 61 cts. pierhead 

 more profit at weaning time than that obtained from the lambs receiving no grain. 

 The average value of each lamb in the lot receiving grain at $5.66 per 100 lbs. was 

 $3.83 per head, and the average value of the grain they ate was 33 cts. per head, while 

 the average value of the other lot not receiving grain at $4.91 per 100 lbs. was $2.89, 

 leaving 61 cts. profit per head in favor of grain feeding. The average of the three 

 trials shows that the grain fed lambs before weaning required 1 lbs. of grain for 

 each 1 lb. of gain that they made over the lambs that had uo grain.
