breeding stock was sent to many parts of the United States and to 

 Porto Kico, Guam, and Japan. The surplus animals produced at 

 the farm do not nearly meet the demand. 



The stallion Troubadour of Willowmoor 6459, the premier sire 

 in this stud, continues to be a very satisfactory sire. The stallion 

 Bennington 5693 is being used rather extensively, and the stallion 

 Mansfield 7255, donated % C. C. Stillman, is also being used. 



In the annual eastern endurance test held at Fort Ethan Allen, Vt., 

 21 horses started, of which 2 were purebred Morgans. One of the 

 latter, Gladstone, bred and owned by the department, was placed 

 second. 



FARM-POWEB STUDIES. 



The bureau has continued its cooperation with the Agricultural 

 Engineering Division of the Bureau of Public Roads in carrying on 

 at the Beltsville farm specific studies relating to the efficiency of 

 horses as a part of the economic studies conducted by the department 

 to determine the cost and utilization of power on farms in certain 

 areas and to study the effect of the introduction of the tractor on 

 farm-power requirements. The results are reported through the 

 Farm Power Committee in department publications. 



CERTIFICATION OF ANIMALS IMPORTED FOR BREEDING PURPOSES. 



Under provisions of paragraph 1506 of the tariff act of 1922 the 

 bureau issued certificates of pure breeding for 1,156 cattle, 230 

 horses, 518 sheep, 1.011 dogs, 7 cats, and 69 foxes. 



POULTRY INVESTIGATIONS. 



POULTRY BEEEDING. 



The general scope of the poultry-breeding work at the Beltsville 

 farm includes improvement in egg production and the maintenance 

 of typical breed character and standard quality. This combination 

 has been effected more successfully with the Single-Comb White 

 Leghorn and the Rhode Island Red than with any of the other 

 breeds. The improvement noted in the Barred Plymouth Rocks 

 during the last two or three breeding seasons has been fully main- 

 tained, and the leading pullet in egg production at this time is of 

 this breed. 



At the Baltimore Poultry Show good specimens of these breeds 

 were shown with accompanying egg records, and favorable comment 

 on their appearance was elicited from poultry breeders and the press. 



About 1,500 hens were trap nested, of which about 1,200 were pul- 

 lets and the remainder yearlings and older hens. Egg production 

 was quite satisfactory during the winter months and was well main- 

 tained during the spring and summer. 



The effort to increase flock production by selective breeding with- 

 out the use of the trap nest is being continued. Late-molting hens 

 showing other external evidences of good production are used as 

 breeding stock in this work. Their progeny seem to mature early, 

 producing a somewhat larger number of winter eggs, with a corre- 

 sponding increase in value. The annual production of the daughters 

 of these late-molting hens also shows a slight increase. Further 

 verification of results will be sought in continuing this work.
