Title: Studies Related to Low temperature Preservation of Bovine Semen
Author: Macpherson, John William
Abstract: No attempt has yet been made to study the "freezability" of the semen of a large number of bulls to compare the effect of freezing on the fertilizing capacity of bulls of normal and lowered fertility. The object of the studies presented in the was as follows:1. Repetition of the work already reported and development of a commercial routine procedure. 2. An attempt to apply other diluents to the freezing procedure. 3. A study to ascertain the optimum concentration rate of addition and equilibration period of glycerol together with the ideal rates of freezing and thawing. 4. Investigation into the fertility of frozen semen from a large number of bulls.
