Fall lamb feeding-. II. .1. GBAMIJCH (NebnUka Sta. Hnl. 110 U'.US). pp. ,?si.— 

 The results of a 67-day lamb feeding experiment beginlng August 21, 1916, and 

 involving 8 lots of 40 lambs each, are reported in this bulletin. The objects 

 were to compare dry lot (hand feeding), cornfield, and Belf-feeder systems of 

 feeding, to study the desirability of clipping fall-fed lambs, and to test the pos- 

 sibility of limiting the corn in a corn and alfalfa ration. The treatment, feed 

 consumption, gains and profits are summarized in the following table:

As shown by the table, although the clipped made slightly larger and cheaper 

 daily gains, the discrimination OB the market against shorn lambs resulted in 

 less profit per head than where unshorn. It is concluded that the fall clipping 

 of lambs is not justified unless the price of wool will more than offset the dis- 

 crimination which the shorn lambs encounter when marketed. 



With respect to limiting the corn ration in fall feeding, it was found that 

 lambs receiving a full feed of corn (lot 1) made a greater profit per lamb of 

 31 cts., due to increased finish, than those receiving a half feed of coru (lot 3). 

 The consumption of alfalfa did not increase in direct proportion to the reduc- 

 tion in the consumption of corn. 



The use of the self-feeder, either with clipped or undipped lambs, did not 

 prove economical in comparison with the straight corn and alfalfa ration. 

 Rape did not prove to be a satisfactory ration for fattening lambs. 



Blue grass pasture supplemented with a limited amount of corn and liuseed 

 meal at the close of the test (lot 7) gave a very satisfactory gain, although the 

 gain was mostly growth and the lambs at the finish did not carry flesh to permit 

 them to sell well. The blue grass produced by far the most economical gains of 

 any ration. 



Cornfield feeding of lambs (lot S) gave a large daily gain, reduced the cost of 

 gain in comparison with dry-lot feeding of corn and alfalfa (lot 1) by 1.65 cts. 

 per pound, and increased the profit by 81 cts. per pound. These lambs carried 

 the most flesh of any lot in the experiment and sold at the highest value per 

 pound on the market. 



The three lots (0. 7. and 8) fed green feed showed in this test relatively high 

 daily gains, and. at the same time, with the exception of the rape-fed lambs, a 

 very cheap gain and as a result a relatively high net profit per head. The blue 

 grass and cornfield lots showed the two highest profits of any in the test.
