Frequently Asked Questions
The duration of a normal reproductive cycle in the cows is 21 days in average. That means we have the chance to perform insemination every 21 days by heat detection system or by using bulls. With FTAI, we can decide on the number of cows we want to get on heat with specific dates. For this purpose, we use a combination of hormones that simulates the normal cycle. We can even induce heat when the cows present anestrous condition, giving them a chance to get pregnant despite their status.
In general, the hormonal treatment takes 8-10 days from the first administration of hormones until the day of artificial insemination. The exact duration and type of treatment will depend on some variables like breed, category, body condition score and reproductive status after individual ultrasound evaluation. Afterwards, there is a waiting time of at least 30 days after insemination to know the results of pregnancy by performing ultrasound. Total duration of the program, including pregnancy diagnosis, is 38-40 days.
The technology has an average worldwide conception rate of 50%, although acceptable percentages may vary between 40 to 60% depending on the case. The percentage is directly influenced by individual physiological response of the females to the treatment.
Non-pregnant females will express heat in 21 days (average). Depending on the new ultrasound evaluation, we can decide if there will be a re-synchronization treatment or if we will follow up with bulls. Generally, programs that combine FTAI + Bulls have higher pregnancy rates per period compared to the ones that only use one method.
For the success of the program, the following are required: proper identification of females, safe and functional facilities, good nutritional condition, health programs which are up-to-date, staff available for handling the animals, and semen from reliable origin (for the farms which provide the semen).
Yes. On the day of the artificial insemination procedure, we bring a tank with semen and all the other necessary equipment, materials, and supplies, to the farm.
Conventional insemination is done when there is required heat detection. In FTAI, whether the animal expresses heat or not, it can still be inseminated. 100% of females treated in the hormonal treatment will be subject to insemination without the need to detect heat.
Natural Service/Mating, unlike FTAI, is the natural breeding system using bulls for a certain period of time or is exposed only when the cows show clear signs of heat.
Heat detection involves the clear recognition of estrus signs. It requires a trained technician and also labor time, making the procedures not accurate most of the time. In FTAI, there is no need for a technician to manually observe those signs. The insemination will be scheduled in advance.
We can identify pregnant and empty cows 28-30 days after insemination. The main advantage of scanning by ultrasound is that it can give an accurate diagnosis earlier than rectal palpation. Real time ultrasound is a reliable and relatively simple method of diagnosing pregnancy, enabling fertility problems to be identified rapidly, and reducing open days.
If the pregnant cow has the proper conditions to maintain the pregnancy, to deliver the calf successfully, and the calf is born in an appropriate environment according to the breed, then yes. Our tropical livestock productivity solutions designed together with one of our alliances abroad includes bulls that will produce resistant calves able to survive to local conditions and to perform as expected.
