Easton's 1897 Bible Dictionary:

Cow
   A cow and her calf were not to be killed on the same day (Lev.
   22:28; Ex. 23:19; Deut. 22:6, 7). The reason for this enactment
   is not given. A state of great poverty is described in the words
   of Isa. 7:21-25, where, instead of possessing great resources, a
   man shall depend for the subsistence of himself and his family
   on what a single cow and two sheep could yield.


Bouvier's Law Dictionary, Revised 6th Ed (1856):

COW. In a penal statute which mentions both cows and beefer's, it was held
that by the term cow, must be understood one that had a calf. 2 East, P. C.
616; 1 Leach, 105.
