RATIONS FOR MILK COWS

plies in particular to the bone- forming salts which occur in milk in large 

 amount. Cows giving a daily yield of 10 quarts of milk suffer a loss of 

 18 grams of lime and 15 grams of phosphoric acid. Unless a sufficient 

 amount of these minerals is provided in the feed, the body will suffer the 

 loss. In providing for this loss in building the ration, the requirements 

 of the animal itself should also be kept in mind. A cow of 1,000 pounds 

 live weight requires for its maintenance 1^ ounces of lime and five- 

 sixths of an ounce of phosphoric acid. Since these two minerals, when 

 combined or mixed with the feed, can be utilized by the animal to the 

 extent of only 33 to 50 per cent, a cow giving 10 liters (2^ gallons) of 

 milk per day should have at least 3^ ounces of lime and 2^ ounces 

 of phosphoric acid in its ration per day. Cows giving over 10 liters per 

 day should have correspondingly more. Where an abundance of good 

 green forage, hay and clover are furnished, the requirements for these 

 minerals will be met. On the other hand, if the ration consists of leached 

 material or stuffs deficient in lime and phosphoric acid from the begin- 

 ning, like slops, pulps, brewers' grains, straw, feed meal, etc., then these 

 minerals must be added in one form or another.
