PREPARATION OF VACCINE LYMPH.
D.
Results in this department are as follows:-
Number of calves scraped for pulp Amount of lymph prepared 116 19,500 c.c.
issued 13,270
in stock at end of year 6,230
Although the number of calves used is less than last year, the amount of vaccine prepared is greater. This is the result of continued effort at improving the yield of pulp per calf and thus lowering the cost of production. The appended table shows the steady success which has been attained in this effort.
