In experiment 1, a retrospective study was performed, with data from 2,709 TAI in Bos taurus and Bos indicus cows with different C\u2010TAI intervals. There was a positive linear effect of C\u2010TAI interval on the pregnancy probability (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.0001). However, there was no effect or interaction with the genotype. When C\u2010TAI intervals were grouped in classes, pregnancy rate differed in groups (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.05). Receiver operating characteristic (ROC) analysis was performed, and it was observed that 52\u2009days would be the better C\u2010TAI interval to maximize fertility in beef cows. According to the previous result, we further stratified into two C\u2010TAI interval groups (\u2264\u200952\u2009days or\u2009&gt;\u200952\u2009days). Cows with C\u2010TAI longer than 52\u2009days (C\u2010TAI\u2009&gt;\u200952) had greater pregnancy rate (56%) than cows with short C\u2010TAI (46%; <jats:italic>p<\/jats:italic>\u2009&lt;\u2009.01). In experiment 2, 18 postpartum beef cows were subjected to TAI protocol at different C\u2010TAI intervals (<jats:italic>n<\/jats:italic>\u00a0=\u00a06 cows per group): 40, 60 or 80\u2009days postpartum. Cows with 60\u2009days of C\u2010TAI had a greater preovulatory follicle diameter than cows with 80\u2009days postpartum (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.05). The C\u2010TAI interval did not affect (<jats:italic>p<\/jats:italic>\u2009&gt;\u2009.05) the ovulation rate nor the proportion of endometrial polymorphonuclear leucocytes. We conclude that C\u2010TAI interval affects pregnancy rate in both Bos taurus and Bos indicus. We recommend a C\u2010TAI interval longer than 52\u2009days to increase fertility of beef cows included in TAI programs.<\/jats:p>","DOI":"10.1111\/rda.14156","type":"journal-article","created":{"date-parts":[[2022,5,12]],"date-time":"2022-05-12T15:40:30Z","timestamp":1652370030000},"page":"936-942","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Effect
