Reproduction
Female Basins breed once every two years upon reaching sexual maturity at four years of age. We breed females that are in good health and at least four years of age with a body weight of at least 1,500 grams. Nighttime temperatures in the November timeframe for both female and males are decreased from a high of 78 degrees to a low of 72 degrees in order to stimulate spermatogenesis, courting, copulation and ovulation. Our daytime highs remain at 82 degrees through the mating process. It is important to maintain daytime high temperatures so that your Basins have the opportunity to warm up during the day to help maintain their immune system.

Males can mature at three years of age and are periodically introduced to females for a week at a time from November through March to insure that copulation has occurred. Ovulation occurs in the female in the February/March timeframe. Birth occurs approximately 150 days from the time of the female's post-ovulation shed. Typically the female will have between 8 and 15 live young. We use ultrasound to track follicular size and in utero embryo status.

Although highly rewarding, breeding Basins is a difficult and stressful proposition with many pitfalls and setbacks. Males can develop respiratory issues due to nighttime cooling and the general stress of mating. Females can develop a variety of complications during parturition including blood clots, retained ovum and infections. In some cases, intervention in the form of drug induced labor or surgical procedures are required to save the female.
