Excellent product Bryan.. Our clients have had great success with this product. We have seen increased conception rates with lap ai and increased semen viability on concentration especially with problematic bucks... I have used fertile aid on problematic bulls and have seen 100% turn arounds on bulls in 30 days.. We placed one of our foundation wtd bucks on it and in 6 weeks he produced 100+ straws; he has not produced semen or fawns the past 2 yrs, semen quality is excellent and now we have semen that will allow him to carry on his line indefinitely.. he is in with does this year and we are beginning to have fawns from him this year!!! We have seen overall increased health, strong does and fawns and an obvious boost in antler production the last 2 yrs. It is a must for the preventative medicine types. By producing a healthy immune system, deer can reach their maximum genetic potential.. God bless..
