cxxii Department of Animal Husbandry 



planned to continue this for at least ten years, and a longer time may be 

 necessary in order to obtain definite results. For this purpose the entire 

 early-Iamb flock of the College is being used. 



At the present time investigations are being actively conducted on ten 

 different subjects, all of which give promise of affording useful material 

 for publication although many will have to be continued for several years. 

 Brief outlines of these investigations follow : 



A study in dairy heredity, by Professor H. H. Wing. This is intended 

 to show the effect of selection and use of improved sires in the develop- 

 ment of a family of cows. The work has accrued in the development of 

 the well-known Glista family. The' investigation was begun in 1887 and 

 will be continued indefinitely. 



The cost of production of winter lambs, by Professor Wing. This is 

 a continuation of the records of the early-lamb flock, a report of the 

 progress of which was published in Experiment Station Bulletin 309 as a 

 continuation of work started in 1903. 



Demonstration of the effect of breed and individuality on the pro- 

 duction of pork, by Professor Wing. The object is to show the relation 

 of breed and individuality in pork production. Weanling barrow pigs 

 are bought in the spring of each year and fed for pork production, records 

 of food consumption being kept. They are sold for pork or slaughtered 

 in the early fall. The study was begun in 1910 and will continue for at 

 least five years. 



Development of the early breeding habit of ewes, by Professor Wing. 

 This is in order to ascertain whether the selection of first-dropped lambs 

 will be followed by early breeding in those selected. From the early*- 

 lamb flock the first ten vigorous ewe lambs are selected each year to 

 replenish the flock, and records are kept of their progeny in successive 

 generations. The work was begun in November, 191 1, and will continue 

 for at least ten years. 



Oats compared with corn and oats for the work horse, by Professor 

 M. W. Harper. The object is to ascertain the comparative value of oats, 

 and corn and oats, as a grain ration for the hard-working horse. The 

 study will include observations on both the condition and the spirit of 

 the horse. The investigation was begun in November, 1910, and will 

 probably be concluded in the spring of 1913. 



The cost of raising colts from birth to three years of age, by Professor 

 Harper. The purpose is to ascertain the cost of producing horses in 

 New York, to include both heavy and light horses ; also, to ascertain the 

 eflfect of different foods on the development and usefulness of the horse. 

 The study was begun in May, 1909, and will be continued for ten years.
