No. 1. — Ration for cows giving i8£ lb. of milk (rougnly if gallons) 



per day. 



Quantities for cows 9 cwt. live weight and giving 165 lb. of milk daily 



are given within brackets. 



39 lb. swedes or 52 lb. yellow turnips (35 lb. or 47 lb.) 



19 lb. oat straw (17 lb.) 



4I lb. decorticated cotton cake (4! lb.) 



Roughly speaking 1 lb. less of decorticated cotton cake might be given 

 if the yield is 12% lb. of milk daily instead of 183 lb. daily. 



No. 2. — Ration for cows giving 30^ lb. of milk (roughly 3 gallons) 



per day. 



Quantities for cows 9 cwt. live weight and giving 27! lb. of milk daily 

 are given within brackets. 



462 lb. swedes or 62 lb. yellow turnips (42 lb. or 56 lb.) 



19 lb. oat straw (17 lb.) 



6f lb. decorticated cotton cake (6 lb.) 



4J lb. undecorticated cotton cake (4 lb.) 



No. 3. — As for No. 2, with hay instead of oat straw. 



Quantities for cows 9 cwt. live weight and giving 27! lb. of milk daily 

 are given within brackets. 



465 lb. swedes or 62 lb. yellow turnips (42 lb. or 56 lb.) 



19 lb. meadow hay (17 lb.) 



5 lb. decorticated cotton cake (4^ lb.) 



3! lb. Indian cotton cake (35 lb.) 



Heavy milkers, giving about 4 gallons of milk daily, 



should have all the foods of the best quality possible, and 

 might be given either of the following additions to Ration 

 No. 3: — 



2 lb. seeds hay. "1 f 2 lb. linseed cake. 



2 lb. linseed cake. V or - 2\ lb. maize meal. 



1 lb. maize meal. j 



Ration No. 1 might also have hay substituted for oat 

 straw, and if so the decorticated cotton cake could be reduced 

 by about 2 lb. daily. This, however, is not quite an exact 

 equivalent. In any of these rations the roots can be con- 

 siderably reduced if desired and a substitute used. 



Cows giving reduced quantities of milk as the lactation 

 period progresses should have the concentrated food given 

 to them reduced, but cows that are heavy milkers and have 

 become reduced in condition, owing to their heavy milk 

 yields, must not have the food reduced too quickly, but must 

 be allowed to regain condition before coming to the next 

 calving. When cows are to be fattened off at the close of
