Feeding rice meal to pigs, C. M. Conner {SoiUh Carolina Sta. Bui. 55, pp. 7). — 

 Corn meal and rice meal were compared with two lots of 3 Berkshire pigs each, 

 the grain ration being supplemented by skim milk. The pigs weighed about 90 

 lbs. each at the beginning of the test, which covered two periods of 29 and 32 days, 

 respectively. The rations were reversed in the second period. Considering the 

 results of the whole test, the average daily gain per pig on the ration containing rice 

 meal was 1.72 lbs.; on corn meal, 1.66 lbs.; the cost of a pound of gain in the two 

 cases being, respectively, 3.84 cts. and 4.63 cts. A pound of gain required 2.48 lbs. 

 rice meal and 9.91 lbs. skim milk as compared with 2.57 ll)s. of corn meal and 10.28 

 lbs. milk. According to the author rice meal when feci with skim milk has a value 

 equal to corn meal.

DAIRY FARMING- DAIRYING. 



Feeding experiments, H. J. Wing {Georgia Sta. Bui. Ii9^j>p. 207- 

 227). — The station has conducted experiments for several 3'ears to 

 ascertain the cost of milk and butter production. The average pro- 

 duction of 9 cows for one year was 5,610.7 lbs. of milk and 278.6 lbs. 

 of buttfer. Records of individual cows are given. Four cows pro- 

 duced milk at an average cost of 5 cts. per gallon and butter at an 

 average cost of 12^ cts. per pound. The average cost of food for the 4 

 cows per year was $41.28 and the profit in milk was $47.26 and in but- 

 ter $46.29. Two other cows produced milk at a cost of 3.7 cts. per 

 gallon and butter at a cost of 8.37 cts. per pound. Shredded corn- 

 stalks was fed with bran and cotton-seed meal to one cow for one 3'ear. 

 The cost of food was $32.2.5, and the proiit in milk $39.01 and in butter 

 $43.43. "The comparative value of cotton-seed hulls and pea- vine hay 

 was tested with 2 cows during a period of 2 years. The nutritive 

 ratios of the 2 rations were, respectivel3% 1:5.40 and 1:5.04. The 

 results were in favor of the cotton-hull ration, the profits being $9.26 

 greater per annum. "If the experiment serves no other purpose it 

 shows the wastefulness of feeding an unbalanced ration." 



The author discusses briefly the following topics: Georgia as a dairy 

 State, dairying the foundation of diversified fariuing. cotton ^^ dairy 

 farming, creameries, the future prospects of dairying in Georgia, and 

 selection of a dairy herd.
