CHAPTER 4.2
The aforementioned “Treatment” effect was comparable for poor and good freezers except
for pre-freeze PM and yield as visualized by the significant interaction terms between “Treatment”
and “Freezability” in Table 1.. For pre-freeze PM, poor-freezing stallions benefitted more from
Androcoll-E treatment than good-freezing stallions. The yield for poor-freezing stallions was more
reduced following Androcoll-E treatment in comparison to good freezing stallions (Fig. 2).
4.2.3.1. Accepted straws and number of AI doses
The number of freezable ejaculates, the number of accepted straws and the AI doses for
good and poor-freezing stallions are presented in Table 2. The effect of “Treatment” on number of
straws accepted (from ejaculates with post-thaw PM ≥30%) was different for good freezers vs. poor
freezers (p
