perspire proportionally, which has a thinning effect; and too 

 low a temperature in the stable is also objectionable, as an extra 

 amount of food is necessary to supply the caloric needed to heat 

 the air breathed to the temperature of the body. 



The water absorbed has an important influence on protein 

 consumption. Experiments have shown that this increase may 

 in some cases reach nearly 6 per cent. Voit points out that 

 it is a mistake to allow too much water to be drunk when live 

 stock is being fattened, and therefore the salt ration should be 

 limited. It has also been pointed out that the proportion of dry 

 matter in a food to water should be for cattle one to four, and for 

 sheep one-half this. There is ample authority on the other 

 hand to show that in cows allowed to drink at will, the milk 

 flow was increased and the fat perceiJtage remained normal. 

 Many other experiments have been made, however, which 

 tend to show that it is very doubtful if there are any advantages 

 in .having water at the constant disposal of cattle, as cows 

 allowed to drink in the yard are as healthy as those depending 

 upon their barn supply. 



As the daily milking means drawing off of water, this must 

 be supplied, and some experts declare that one had better allow 

 the cattle to drink twice, once in the morning and once in the 

 evening, rather than only once. Which is the best mode of 

 keeping the water remains an open question. If the stock is 

 being fattened it is better to have the supply in the stable 

 rather than compel the animals to make long tramps to drink 

 at some distant stream. 



Water drunk and Some experiments have been made to determine the amount 

 its influence. o f wa ter drunk by larnbs during fattening, and the results show 

 that it varied with the food. For sugar beets it was 0.4 Ibs., 

 while with oil meal it reached 4.8 Ibs. The temperature of the 

 water has an important influence on the flow of milk. Experi- 

 ments. in this direction made at the Wisconsin station with two 

 lots of cows, showed that when the water was at 70 F. on the 

 one hand and 32 F. on the other, in the first experiment the 

 warm water gave 6 per cent, more milk than did the cold water; 

 in the second experiment this difference was very much less. 

 An interesting fact furthermore was revealed, viz., that with
