Evaluation of effectiveness of an innovative semen extender (Formula^®) comparing with a traditional extender (Lepus^®) for artificial insemination in rabbits does

Figures & data

Figure 1. Effects of the two extenders (Formula^®, Lepus^®) on total motility of rabbit semen (least square means) × time interaction. ^a,bDifferent superscripts within the same time of storage indicate a significant difference (p < .05).

Figure 2. Effects of the two extenders (Formula^®, Lepus^®) on progressive motility of rabbit semen (least square means) × time interaction. ^a,bDifferent superscripts within the same time of storage indicate a significant difference (p < .05).
