Feeding and Care of Pigs

fed in the dry lot and the same ration on forage. The 

 result of feeding as large a proportion of nitrogenous 

 supplement in the forage as in the dry lot was to supply, 

 in most cases, an excess of protein to the forage-fed pigs. 



The summarized statement of these experiments shows 

 that the pigs in the dry lot gained an average of .85 pound 

 daily, while those on forage gained 1.17 pounds. This 

 is a difference of practically ^ pound daily for each pig. 

 In other words, the pigs on forage were 33 pounds heavier 

 at the end of 104 days' feeding. When rapid gains and 

 an early market are sought by the feeder, the importance 

 of providing green crops is shown by the fact that the 

 pigs on forage were practically as heavy at the end of 

 2^ months' feeding as were those in the dry lot at the 

 end of 3j months' feeding. 



The average amount of concentrates (corn -f- supple- 

 ment) required to produce 100 pounds of gain was 413.25 

 pounds for the dry lots and 351.29 pounds for the forage 

 lots. The green feed consumed by the forage lots caused 

 an average saving of 62 pounds of concentrates in the 

 production of each 100 pounds of gain. Whether or not
