Animal Husbandry Investigations in 1916. l37 



(b). The breeder or farmer undertaking such a coopera- 

 tive test under the directions furnished by the Expermient Sta- 

 tion must agree to keep a careful and accurate record of the 

 milk of the animals on test over a period of time mutually agreed 

 upon (7 day; 14 day; 30 day; 90 day; or one year). 



(c). Anyone desiring to take up such a test should write 

 to the Director of the Maine Agricultural Experiment Station 

 asking for an application blank form, which he should fill out 

 and return at once. This form is given on page 138. 



(d). Samples of the milk of the animals on test shall be 

 regularly taken, according to directions which will be furnished, 

 and sent to the Maine Agricultural Experiment Station. There 

 an analysis of the milk will be made and the necessary calcula- 

 tions for making proper age corrections for the animals con- 

 cerned will be carried out. An official report will then be ren- 

 dered to the breeder as to whether in the particular case involved 

 the sire produced a daughter which was a better or a poorer pro- 

 ducer than her dam when both are compared on an equal age ba- 

 sis. The report will be in the form given on page 139. 



(e). The only expense to the breeder involved in having 

 such a test carried through is the expressage on the samples 

 of milk to Orono, and postage on reports. This cooperative 

 daughter-dam testing project will be open on precisely equal 

 terms to owners of grade cattle as well as owners of pure-breds.
