MARKET MILK IN SOUTHEASTERN LOUISIANA. 3 
The dairyman kept itemized accounts of expenses incurred between 
monthly visits and reported these items to the field agent. Monthly 
records were also kept of the purchase or sale of cows, calves, hides, 
of outside bull service, and of other miscellaneous information. 
Accurate records of calves born and first-hand information on the 
condition and methods of handling manure were collected sys- 
tematically. 
The collection of monthly records lessened the influence of unusual 
circumstances at the time of any particular visit. The use of the 
records of all the herds for each month made it possible to obtain 
representative data for each month, season, and year. Records were 
obtained the second year as a check on the first year's work and to 
increase the quantity of data for study. 
REQUIREMENTS FOR PRODUCING 100 POUNDS OF MILK. 
To obtain more uniform results and to overcome the effect of 
fluctuating prices, money values have been eliminated wherever 
possible. Feed requirements in pounds and the labor requirements 
in hours make it possible to apply current prices.
