New South Wales Choicest Butter* 



Percentage of Butter-fat and Water. 



L. T. MacINNES, Dairy Expert. 



In connection with the testing of pure-bred dairy cows, under "the United. 

 Pure-bred Dairy Cattle Breeders' Association's testing scheme, the standard 

 for estimating commercial butter from butter-fat was last year fixed at 83 lb. 

 of butter-fat in 100 lb. of commercial butter. In order to verify this ratio, 

 and at the same time ascertain as accurately as possible under practical 

 conditions the fat and water content of New South Wales choicest butter 

 manufactured under the system of neutralising and pasteurising of cream 

 before churning now generally adopted, I arranged to obtain samples during 

 every month for a period commencing October, 1918, and ending September, 

 1919, from butter factories representing all the varied conditions under 

 which butter is manufactured in this State. These samples were transmitted 

 regularly to the Chemist's Branch of this Department for analysis, and the 

 results of the analyses are now made available. 



The samples were taken from the following butter factories : — Bega, Nowra, 

 Goulburn, Singleton, Scone, Tamworth, Dungog Co-operative, Upper Manning 

 River (Wingham), Manning River Co-operative Dairy Co., Macleay River 

 (Kempsey), Upper Bellinger, Ulmarra, Casino, Kyogle Central, North Coast 

 Co-operative Co. (Lismore), Foley Bros. (Lismore), Nimbin, Ballina, North 

 Coast Co-operative Co. (Byron Bay and Murwillumbah), and Tweed River 

 Butter Co. 



In working out the average percentage of buttei'-fat and water for each 

 month from the samples of choicest butter analysed, the actual output of 

 choicest quality butter of each factory concerned was taken into account. 

 This was also done in arriving at the average content for the whole year. 

 The following table gives the total output of choicest quality butter of these 

 twenty-one butter factories for each month of the period covered by the 

 investigations, with the average fat and water percentage contained therein : —
