CARABAO COW WITH THREE DAYS OLD CALF. 



Kiii. lli.i 



The Philippine carabao is essentially 

 the same as the buffalo or water buffalo 

 of India, China, Java, and other 

 oriental countries, except for slight 

 variety differences as to size and shape 

 of horn, color and texture of skin, and 

 slight differences in conformation. The 

 writer examined the literature from the 



above countries but has not come across 

 any observations pertaining to this 

 question. 



The animals observed so far are as 

 follows : 



The gestation of the carabao, there- 

 fore, is approximately 320 days, or 

 forty days more than the cow (280),

Observations were also made on the

 parturition, and this gave us : 



This period was determined by try- 

 ing, every two days after calving, to 

 mate the animals. These latter figures 

 are simply offered as observations and 

 may not hold true in every instance.
