20a EXPERBIEXT STATION. [Jan. 



It can be said that the digestibility of the barley hulls has been greatly improved, 

 but the treatment has been substantially without effect upon the cottonseed hulls and 

 the flax shives. The method of treatment — namely, with dilute sodium hydrate — 

 would probably not prove economical on a large scale. 



Animal Feeding. 



Chemistry Project 10. "Experiments in feeding pigs." 



Professor Lindsey and Assistant Professor Archibald. 



This project cohsisted in the taking of records on feeding different amounts of semi- 

 solid and dried buttermilk. Results indicate that these materials are uneconomical 

 when used for pork production. Work under this project is completed, but results 

 have not yet been submitted for publication. 



Chemistry Project 16. "Vitamines as aids in the production of growth in pigs." 



Professor Lindsey. 



As with the above, work has been completed, temporarily at least. 



Chemistry Project 17. "Attempting to secure a substitute for milk in the 

 growing of young calves." 



Professor Lindsey and Assistant Professor Archibald. 



Four different materials or combinations of materials were used as milk substitutes, 

 with a total of twenty-three calves used in the investigation, but with four discarded 

 as unsatisfactorj'. In these different mixtures limited amounts of soluble blood flour, 

 dried skim milk, oat flakes, corn meal, wheat middlings, coconut meal, peanut meal, 

 linseed meal, starch, glucose, milk sugar, calcium chloride and salt were used. Fair 

 results were secured. 



Chemistry Project 18. "To determine the mineral constituents of forage crops." 

 Professor Lindsey and Assistant Professor Archibald. 



This study has been fruitful in two directions: first, the collection of about sixty 

 samples of coarse fodders, principally hay and corn silage, from different parts of the 

 State; and secondly, determination of the mineral constituents in the ordinary concen- 

 trates which are used in the State. It is expected that this work will be completed 

 during the coming winter. 



Chemistry Project 19. "The value of inorganic calcium phosphate in the pro- 

 motion of growth and milk production. 



Professor Lindsey and Assistant Professor Archibald. 



Up to date no effect favorable or otherwise of feeding inorganic calcium phosphate to 

 cows, young stock and sheep has been noted. Despite this failure, however, these in- 

 organic salts are widely used in the State as constituents of animal feeds. Their value 

 is yet to be proven. 



Miscellaneous. 

 Chemistry Project 3. "Summer forage crops." 



Professor Lindsey. 



Very little work was done on this project. There are no results worthy of extended 

 comment. 



Chemistry Project 4. "Record of the station herd." 



Professor Lindsey. 



As in previous years complete records on the food cost of milk produced by the station 

 herd have been kept.
