TRAINING LENGTH 2 hours. 3-4 days.
EASE OF LEARNING 10 out of 10 learn properly (due to this new and more practical process) 2 out of 10 learn properly (due to complexity of process)
EFFECTIVENESS 70-80% Conception Rate. 40-60% Conception Rate (highly dependant on the technical skill level)
EFFICIENCY Shorten calving intervals (more cows are pregnant at first service) Save on semen = $$ savings Important money loss due to extended calving intervals. Commonly, more semen and money wasted.
AVAILABILITY Anyone at the ranch can learn and implement on the spot. Only when a technician is available and present (cost of technician is expensive for small breeders)
TIMING & PRECISION Always ready. Only if the technician is there on time.

The Deer Inseminator is an innovative insemination method designed and perfected by Dr. Marco A. Hidalgo, MSc, DVM. Back in 1970 he founded the first private cattle semen production and marketing company in Mexico; nowadays, he is still active in developing reproduction programs in cattle ranches inside and outside the country.

Our goal is to provide deer breeders total flexibility in their AI scheduling, with pregnancy warranty and minimal stress on the animals. This innovative technique allows for high conception rates without the need for costly equipment and high-risk, invasive surgery on the animals. This simple, scientifically developed method is based on applying the semen through the cervix directly into the uterus.

  • No medication
  • No surgery
  • No high-cost equipment
  • Minimal stress and risk on the animal
  • Training Available
  • Mexico Patent: 20 1 208
  • US Patent: 6 071 231
  • We have achieved the same conception rate as laparoscopy.


"Our "RamGo" system is specially designed for sheep, goats and deer. It has a small device in the shape of a pear with cannula, similar to the device of "Torito Express".

"The "RamGo" device is unique in its type, it can pass through the first cervical ring of the sheep, which is usually very difficult to achieve with other artificial insemination systems. Conception rates with "RamGo" can be the same as laparoscopy.
