SUMMARY OF TWO YEARS' WORK. 



Tables XVIII and XIX present results of the two years' work 

 in condensed form. As all of these data have been discussed in 

 this bulletin or Bulletin 179, extensive comment in this connection is 

 unnecessary. 



Since many factors such as initial weight of lambs, breeding of 

 lambs, management previous to beginning- of experiments-, roughage 

 fed, length of feeding period, and weather conditions varied, it is 

 not possible to account definitely for the variation in gains during the 

 two years. Other feeders in the vicinity reported lower gains 

 in 1906-7 than were obtained in 1905-6. 



TABLE XIX Summary of manure for two years. 

 1905-6, 40 lambs, 112 days. 



1906-7, 44 lambs, 115 1-2 days. 



RATIONS 



In no instance did any ration prove of outstanding excellence 

 above the others on the basis, of amount of feed required to produce 

 100 pounds gain. So far as rations are concerned the chief use to 

 be made of the data obtained is to emphasize the necessity of choos- 

 ing economical as well as efficient feeds. While the food consump- 

 tion per hundred pounds gain varied comparative^ little in either 

 experiment, the cost of 100 pounds gain was widely different in 

 several instances. A consideration of the cost of feeds involves a 

 study of market quotations, and as is shown by the tests reported, 

 is very necessary if the greatest profits are to be realized. A ration 

 might be economical one year and manifestly extravagant another 

 year. 



NITROGENOUS CONCENTRATES. 



In general, if the feeding of linseed oilmeal or of cottonseed 

 meal to lambs receiving corn and clover, of corn and alfalfa is to be 

 attended with profit, either of these concentrates should be but little, 

 if any, higher in price per pound than corn.
