560 FEEDS AND FEEDING 



same value per ton. In 2 similar trials at the Kansas Station 35 by Pat- 

 erson and Winchester, linseed meal was worth slightly more per ton 

 than cottonseed meal, when equal amounts were added to a ration of 

 shelled corn, alfalfa hay, and corn or sorghum silage. From these ex- 

 periments we may conclude that these feeds are both excellent supple- 

 ments, but that when just enough is fed to balance the ration, choice cot- 

 tonseed meal is somewhat the more valuable for fattening lambs, because 

 it is richer in protein. 



Even when no legume hay, rich in protein, is fed to fattening lambs, 

 no more than one-fourth to one-third pound of linseed or cottonseed meal 

 per head daily is needed to balance the ration. Owing to the poisonous 

 properties of cottonseed meal when fed in excess, a larger amount than 

 this should not be fed to lambs or sheep. In a trial at the Oklahoma 

 Station 36 by Magee and Darlow, lambs fed 0.55 Ib. cottonseed meal a 

 head daily, with Sudan hay and darso silage, went oif feed after 70 days, 

 while a lot fed a smaller allowance of the cottonseed meal continued to 

 make good gains. In combination with grain, legume hay, and silage, 

 one-eighth to one-fourth pound cottonseed meal will provide a well- 

 balanced ration. Linseed meal is an excellent supplement for the breed- 

 ing flock, and cottonseed meal is also satisfactory, when not fed in ex- 

 cess. (883) Linseed cake and cottonseed cake of nut or pea size are 

 better relished by sheep than finely ground meal. 



Cold-pressed cottonseed cake, which contains all the hulls and is con- 

 sequently lower in protein and higher in fiber than cottonseed meal, was 

 found by Gramlich and Savin in 2 trials at the Nebraska Station 37 to be 

 worth only 72 to 75 per ct. as much per ton as cottonseed meal. (248) 



856. Other protein-rich concentrates. Field peas and soybeans are ex- 

 cellent protein-rich feeds for sheep and lambs, but are commonly expen- 

 sive. (261, 256) Of several concentrate mixtures tested for fitting year- 

 ling wethers for shows, the best results in finish of the lambs and firmness 

 of flesh were secured with a mixture of peas, oats, and bran in trials 

 by Humphrey and Kleinheinz at the Wisconsin Station. 38 In a trial 

 by Iddings at the Idaho Station 39 lambs fed 1 part field peas and 3 parts 

 barley, with mixed hay for roughage, gained 11 per ct. less than where 

 pea sized linseed cake was used in place of the peas. The lambs fed peas 

 required 11 per ct. more concentrates and 17 per ct. more hay for 100 

 Ibs. gain than those fed linseed meal. 



Soybeans have been compared with choice cottonseed meal as a supple- 

 ment to shelled corn, corn silage, and clover hay in 3 trials by Skinner 

 and King at the Indiana Station. 40 The lambs fed ground soybeans made 

 only a trifle smaller gains than those fed cottonseed meal and required 

 but little more feed for 100 Ibs. gain. In these trials ground soybeans 

 were worth 11 per ct. less a ton than choice cottonseed meal.
