During the 2018/2019 breeding season, 2 FTAIs plus intermediate transfers with bulls were used. This strategy was planned and monitored by the veterinarian José Henrique Tanner da Faz. Santana do Arvoredo – Vila Bela da Santíssima Trindade – MT, also a partner of Qualitas. In addition, veterinarian Wesley Carneiro na Faz. Caititu de Campinorte - GO, also had experience with the strategy and Agropontieri de Goiatuba - GO, has already been inseminating with observation of post-FTAI estrus for several years. Due to the excellent results Faz. Mata Verde and other Qualitas partner farms decided to adopt the strategy. The Farm Mata Verde practiced a 69-day Mounting Station for two harvests, starting on October 31st and ending on January 8th. In this period, 2 FTAIs were carried out, and after the 2nd IATF, certified Qualitas bulls of about 2 years of age were placed in the proportion of 1 bull for about 30 dams. Nilson Michels, one of the company's partners, inseminates 100% of the sows helped by his wife Liliane and the cowboys in a single corral. The management of births is carried out by 2 cowboys, in mobile maternities.
In Monta Station 2019, the following changes were made:
• The start was brought forward to the 20th of October and the end to the 23rd of December, decreasing to 64 days;
• Intermediate transfer was adopted after the 1st and 2nd IATF with Qualitas certified bulls in the proportion of 1 bull for 15
