 Trial Comparing Razorback with Cross-Bred Razorback and Improved Breeds of 

 Hogs, by VV. L. Carlyle i E. S. R., 14, p. 1000): and Canker Sore Mouth in Young 

 Pigs, by W. L. Carlyle. 



It is stated that the most important feature of these investigations was the experi- 

 ments undertaken to determine the relative value of different rations for the pro- 

 duction of fat and lean, since the market demands pork with a large percentage of 

 lean meat. Rations with a high protein content, it is stated, were more conducive 

 to the development of the internal organs of the pigs than the rations low in protein, 

 and also to a distribution of a greater amount of lean with the fat in the carcasses. 



"Whole corn compared with corn meal for fattening pigs, W. A. Henry 

 ( Wisconsin Sta. Rpt. 1903, pp. 43-45). — Experiments previously reported (E. S. R., 

 14, p. 999) on the comparative value of whole and ground corn for fattening pigs are 

 summarized. On an average 105 pigs required 5.16 lbs. of feed per pound of gain 

 on a ration of dry shelled corn and middlings, as compared with 4.8 lbs. required by 

 an equal number on a ration of corn meal and middlings. 



In other words, there was " a saving of 36 lbs. of feed for each 100 lbs. of gain 

 made by the hogs. This shows a gain by grinding the corn to meal of 6.9 per cent, 

 or, say, 7 per cent in round numbers. While the direct advantage from grinding c< >rn 

 to meal was about 7 per cent, in these experiments there was a second advantage 

 secured in that the hogs getting corn meal made more rapid gains than those fed 

 shelled corn." 



Feeding draft horses for the market, J. W. Covekdale (Iowa Agr.,4 (1904), 

 No. 6, pp. 23S-240). — On the basis of experience the author considers that the essen- 

 tial points in feeding draft horses for the market are "the selection for type ami 

 constitutional vigor, the careful starting on grains, the ration at full feed, toning up 

 of his system, the place in which he is fed, the care of the stable, the grooming, exer- 

 cise and training before selling." A corn ration is recommended at first, with a 

 little oats once a day with a sprinkling of bran, and later these feeds in increasing 

 amounts. 



"Corn had best be given in the ear by itself. It maybe fed morning and evening. 

 A handful of flax meal should be fed just after watering in the morning. Oats and 

 bran mixed make a good feed for dinner. The amount of each feed should be 

 according to the appetite of the horse. Some horses eat more than others. How- 

 ever, a heavy horse on full feed will eat about 18 ears of corn twice a day; 15 qt. of 

 oats and bran mixed, and about 10 lbs. of hay." The hay, it is said, should be given 

 in small amounts 5 times per day. 



Poultry experiments, C. Cuktice (Rhode Island Sta. Rpt. 1903, pp. 269-273). — 

 During the year the poultry work of the station has been principally with the incu- 

 bation and brooding of chickens. In the incubation experiments 8,677 eggs have 

 been set in incubators. Of these, 83 per cent were fertile, and 46 per cent of the 

 fertile eggs, or 38.6 per cent of the total number of eggs, hatched, the efficiency of 

 hatching under various conditions ranging from to 84 per cent. 



( hving to unfavorable circumstances the brooding experiments were not considered 

 satisfactory. "The results have varied from 100 per cent downward." The other 

 poultry work at the station and plans for future studies are very briefly spoken of.

 ami Expt. Union Rpt. 1903, pp. 40-42). — A brief account with discussion of cooperative 

 experiments on hatching chickens with incubators.
