FEEDmG, E. E. Lloyd, M. S. (pp. 2-4). — Feeding experimenU with 

 milch coics. — " To determine the relative values of difterent foods for the 

 pioductiou of milk aud butter " six lots of 5 cows each (4 grade Jerseys 

 and 1 grade Holstein) were fed the following rations per animal daily 

 during 5 weeks, the first week being regarded as preliminary : 



Lot 1, 9.2 pounds Bermuda hay + 9.5 pounds raw cotton seed. 

 Lot 2, 10.5 pounds Bermuda hay -f- 10.6 pound.s roasted cotton seed. 

 Lot .3, 8.5 pounds Bermuda hay -f 10.4 pounds steamed cotton seed. 

 Lot 4, 9.9 pounds Bermuda bay -f 9-9 pounds corn meal. 

 Lot 5, 8.5 pounds timothy hay -f 9.5 pounds raw cotton seed. 

 Lot 6, 10.9 pounds Bermuda hay -f- 9.5 pounds cotton-seed meal. 



" The cows in the different lots averaged as nearly as possible the 

 same length of time from calving, and the yield of each lot did not vary 

 more than U pounds from any other lot." The milk of ca«'h cow was 

 weighed separately, and tests of the fat contained in the mixed milk of 

 each lot were made morning and evening by the Babcock andBeimling 

 methods. The tabulated data given include for ea<'h lot the gain in 

 live weight, the production of milk and of butter fat (as calcnlatcd 

 from the analyses of the milk), and the cost of the same. The financial 

 results arc based on timothy hay at .^20. SO, Bernuida hay at $12..1(i. 

 I'aw cotton seed at •"?(». roasted cotton seed at 87.20. steami'd cotton 

 seed at -^fLoO, cottonseed meal at ><2(>, and corn m« al at >'2."> jier ton. 

 nuiking no allowance for the value of the mannrr. 



According to the results as taludated, lot 1, r«'ceiving Bermuda li;i,\' 

 and raw cotton seed, juodnced Initter and milk at the lowest cost. 



This lot produced milk at a cost of 7.7 cents per pillion and Initter at a cost of 

 17.4 cents per pound, hut the hut tor was of poor quality, heiug sticky and of poor 

 flavor. The most expensive milk and hutt<'r Avere from lot 4. which was fed on 

 Bermuda hay and corn meal, the milk costiuj; 12.8 cents per gallon and the hutter 

 41.4 cents per pound. [This ration cost more than twice as much as that given lots 

 1 aud 3, and was hy f;ir the most expensive ration fetl.] The hutter frtun this lot 

 was of excellent quality, hut not so good as that from lot .S. and cost more than 

 twice as nnuh. 'J'his lot also slutwed a loss of llcsh of ;^4 ])ounds. while lot 3 gained 

 214 jjouuds. 



As between Bermuda hay and tinnttliy hay (lots 1 and ."►) the result> 

 were in favor of the fonner. Lot ■"> (timothy) "gained well in flesh, 

 but produced only a small anuumt of milk."' Based on the gross cost 

 of the food, the milk i^roduced by this lot cost 12.S eents per gallon, 

 and the butter 20. .5 cents ]»er i>onnd. as eomiiared with 7.7 cents and 

 17.4 cents where lU^rmuda hay aud cotton seed were fed (lot 1). "Had 

 the timothy cost the same as did theBernnula hay. the cost woidd ha\ c 

 been only 0..~) cents per gallon for the milk and 21.0 cents for the buttei." 



The author believes from the work done at the station up to tin 

 present time that in that section —
