34^ Pig Feeding and Pork Production. 



[JULY, 



by the pigs were equivalent in feeding value to 335 cwt. of 

 barley, and were fed at a cost of £431 95. They would, there- 

 fore, correspond to barley fed at £1 5s. 6d. per cwt. or £5 is. 

 per qr. 



On the other hand, the home-grown foods consumed by the 

 pigs during the year were equivalent in feeding value to 258 

 cwt. of barley, and these were produced at a cost of £153 13s. gd. 



They would, therefore, correspond to barley fed at iis. yd. 

 per cwt., or £2 6s. ^d. per qr. 



It is evident, therefore, that if pork is to be produced on the 

 most economical basis, as large an amount as possible of home- 

 grown foods should be available to feed them. 



These figures also furnish data from which milk products 

 such as separated milk and whey fed to the pigs on the farm 

 may be valued. The 3,272 gal. of separated milk fed have 

 approximately the same feeding value as 31 cwt. of barley. 

 If the barley is valued at £1 5s. 6d. per cwt., the price at which 

 the barley equivalents in the purchased feeding stuffs were 

 purchased at the current rates, it means that the 3,272 gal. 

 were worth roughly £39, and that the separated milk should 

 be charged at '^d. per gal. for feeding purposes. Similarly, the 

 5,000 gal. of whey fed to the pigs have about the same 

 feeding value as 36 cwt. of barley, and would, therefore, be 

 worth approximately £45, or 2d. per gal. for feeding purposes. 



Feeding Standards. — It is interesting, also, to note how 

 closely the average ration fed to the pigs during the year 

 adhered to the standards suggested by Kellner, and generally 

 accepted both in England and Germany. 



As the average weight of the 92 pigs sold during the year was 

 196 lb., of the 61 pigs in stock at the beginning of the year 

 100 lb., and the 73 pigs in stock at the end of the year 148 lb., 

 it is most probable that the average live weight per pig on the 

 farm throughout the whole year would be approximately 150 lb. 



The daily ration, therefore, if it fitted in with Kellner' 3 

 standards, should be such as to include approximately : — 



Ik' ^M'^ T^^T- " • • ) per 1 ,000 lb. live 



; T.^ 1 . (weight per day. 



2 1 lb. of starch equivalent .. ) 



The total amount of dry matter fed during the year was 

 412-4 cwt., and of digestible protein 1087 cwt. The starch 

 equivalent of the dry matter fed was 494-6 cwt., from which it 

 follows that the average daily ration fed to the pigs throughout 

 the year actually contained — 



26 lb. of dry matter per i ,000 lb. live weight per day instead of 30 lb. 

 suggested by Kellner.
