vey; add the quotients together; divide by the total area of field 

 crops on the farm in question. 



9. Number of animals of each kind. This should be the average 

 number of each kind of stock on hand at different times during the 

 year. In the case of cows, horses, flocks of sheep, sows, and poul- 

 try the average of the first and second inventory is usually suffi- 

 cient, except when some are raised and sold between dates of 

 inventories. In the case of feeder steers or sheep the actual num- 

 ber fed should be given. When calculating the number of animal 

 units for pigs that are raised and sold during the year, five such 

 animals are usually considered an animal unit when the value 

 indicates they had reached some 200 pounds or more per head in 

 weight. If sold when the weight is much less than 200 pounds, 

 10 such animals are counted an animal unit. 



10. Number of animal units for each kind of stock. An animal 

 unit is the equivalent, from the standpoint of feed required, of a 

 full-grown cow or horse. It is customary to count as an animal 

 unit 2 head of young cattle or colts, 5 hogs, 10 pigs, 7 sheep, 14 

 lambs, or 100 poultry. In the case of feeder steers and feeder 

 sheep the number of animal units calculated should be reduced in 

 proportion to the time on feed as compared with the full year. 

 Thus, 30 steers on hand six months will equal 15 animal units for 

 the year. 



11. Percentage of animal units of each class. That is, divide 

 the number of animal units of each class by the total number of 

 animal units on the farm. 



12. Crop area and pasture area per animal unit. First, includ- 

 ing work horses; second, excluding work horses. 



13. Crop area and pasture area per cow. This calculation is 

 important in dairy regions. 



14. Total net receipts from each kind of animals except work 

 horses. 



15. Total net receipts from all kinds of animals except work 

 horses. 



16. Total net receipts per animal unit for each kind of animal 

 except work horses.
