How to Improve Breeding Success in Does

1 Boost the Buck’s Fertility

Conception hinges on the buck’s sperm count and vigor, so restoring his potency is the foundation.

Tease with an estrous doe in the same space to revive testicular function.

Massage the testicles twice daily for 3–5 minutes to stimulate tissue growth — keep the pressure gentle.

Hormone therapy: inject 0.5 mcg of an ovulation-stimulating hormone every other day for five doses to lift semen quality. Remember sperm take 50–60 days to regenerate, so patience is required.

2 Time the Doe’s Estrus

Mating at peak estrus raises conception by 20–30%. For does that struggle to cycle, use teasing or hormones such as hCG, LH, or a combined formula. Helpful tricks: mix 10% epimedium or half a qian of leek seed into feed for ten days; add carotene at 40 mg per kg of feed; and clip the fur around the vulva before mating. Pick the method that fits the doe.

3 Other Measures

Use repeated or double mating to multiply the chance of conception, matching the rabbit’s ovulation pattern.

Pregnancy-check at day eight. If she is not pregnant, rebreed to shorten the open period; if she has reproductive disease, treat or cull.

With sturdy bucks and does, add nutrition and use frequent or semi-frequent mating to raise both conception and litter speed.
