first milking in the new quarters one cow gave 2 pounds less milk 

 and that this milk contained 1.0% less fat than at the last milking 

 before leaving her home quarters, but at the second milking in the 

 new quarters the loss of the first milking was recovered and she 

 continued her normal flow of milk. The other cow showed the 

 same tendency, giving nearly I pound less milk testing 1.5% less fat 

 than at the last milking before the change of quarters, but recov- 

 ering her normal production soon after. Hill reports results from 

 7 cows driven 3^2 miles from one barn to another in which there 

 was a general increase in yield of milk during two days following 

 the change of quarters, but six of the seven cows gave milk of a 

 poorer quality after the change. The effect of transportation and 

 change of quarters with cows exhibited at fairs has frequently been 

 noticed, and the so-called "milk tests" at these fairs for one or two 

 days only, are likely to give an erroneous impression of the milk 

 producing qualities of the cow under normal home farm conditions. 



N. Dehorning. 



192. A number of observations on the influence of dehorning 

 of cows on the amount and richness of the milk given by the cows 

 have been made. Babcock reports results of dehorning on 10 

 cows. The details of five records are as follows :

After Dehorn'g 8.1 3.9 7.2 3.8 9.1 4.6 6.0 2.7 3.7 3.6 



The results obtained from the five other cows were similar to 

 these. There was a decrease in both amount and quality of the 

 milk at the first milking after dehorning, but this was only tem- 

 porary, as by taking the herd of ten cows as a whole, the weight 

 of milk for two days before dehorning was 289 pounds, and two 

 days after dehorning was 244 pounds, while for the next two day 3 

 it was 280 pounds. This shows that cows can be dehorned witho.it 

 seriously affecting their milk yield. 



Other observers report similar results, although Doane found 

 in observations made with a number of cows that they failed to 

 regain the normal flow of milk until about 8 days after dehorning.
