Composition of Goats' Milk (California Agricultural 

 Experiment Station) 



Analyses of the milk from tlie does in tlie University herd are 

 made weekly. The averages given below are the result of the analyses 

 made weekly during the entire lactation periods. With one exception 

 these does were Toggenburgs.

In the Bureau of Animal Industry Farmer's Bulletin No. 920, on 

 Milk Goats, the following analyses (?f goat and cow milk are given.

It may be remarked that the analyses given by the Geneva station 

 and the California st.ation are based for the most part on the milk of 

 Toggcnburg goats, of relatively high yields of milk. The figures of 

 the B. A. I. are stated to be based on the milk of common American 

 goats, of low yield.
