“…In vitro matured studies have been carried out at 41 °C, to evaluate the damage caused by thermal shock in COCs and it has been observed that the damage in the ZP, with a greater number of pores, as well as abnormalities increase after 22 h of exposure to high temperatures [49]. The cows in this study were kept exposed to grazing weather conditions throughout the year and the highest Tmax occurred in HD [18]. It has been observed that as heat stress increases, animals activate physiological mechanisms to release body heat [50].…”

“…The study was carried out in three climatic seasons (EST): hot dry (HD, March-May, with Tmax and RH of 31.6 ± 1.0 °C and 77.2 ± 1.1%), hot humid (HH, June-October, with Tmax and RH of 31.4 ± 0.4 °C and 84.7 ± 1.0%), and fresh dry (FD, November-February, with Tmax and RH of 26.8 ± 0.5 °C and 84.6 ± 0.3%) [18] in Veracruz, Mexico, at 19° 11'N and 96° 20'W, at 23 m amsl , with average annual temperature and precipitation of 24.8 °C and 1,525.8 mm [15]. The climate of the region is AW0(w)(i')gw'', hot sub humid with rains in summer [14].…”

“…Although OPU-IVF are reproductive technologies that contribute to rapidly increasing herds of pure animals, inter annual season variability with Tmax and RH higher than 30 °C and 84% [14,15] can decrease their success. In recent years, 90% of the annual pluvial precipitation has occurred in the hot humid season,while in the fresh dry and hot dry only around 5% in each, with a total of seven months of drought [16][17][18]. In the female bovine, the increase in body temperature reduces the follicular population and decreases the size of the preovulatory follicles,in addition, a higher degree Celsius in the temperature of the follicles in the ovaries inhibits ovulation [19].…”

“…The criollo breeds Romosinuano and Tropical Milking are Bos taurus naturalized to hot climates of the tropical region, with populations established in different countries of the Americas, although relatively small of thousands of individuals [22][23][24]. Studies have been carried out to determine the effect of Tmax and RH on the fertility of TM heifers and cows,it was found that the lowest pregnancy, less than 50%, occur in the hot dry season with Tmax greater than 27 °C and RH of 85% for heifers [18], but no season effect was observed in cows [25]. When comparing, Brahman and Angus breeds to determine the effect of heat shock on oocytes cultured in vitro at 41°C, oocytes had greater cleavage, with embryos of more than eight cells four days after IVF [26].…”

One of the main factors that influence the fertility of cattle in grazing systems in hot tropical climates is heat stress. The objective of this study was to evaluate the effect of season, breed, hormonal and physiological condition on the quantity and quality of cumulus-oocyte complexes (COCs) and embryos produced in vitro, from Romosinuano (RM) and Tropical Milking (TM) donors. Three ovum pick-up and in vitro fertilization (OPU-IVF) were performed, one per season; hot dry (HD; 10, 10), hot humid (HH; 9, 9) and fresh dry (FD; 7, 10) in RM and LT donors. Serum levels of cortisol, insulin and glucose were measured, in addition to heart rate (HR), respiratory rate (RR) and rectal temperature (RT). Effect of season x genotype interaction (p≤0.05) was observed in all COCs variables and only in cleavage embryos (CLI) (p≤0.05). Body weight (BW) affected all COCs variables (p≤0.01), except unviable (UNV) although affected degenerated embryos (DEG) (p≤0.01) and total blastocysts (BLAST) (p≤0.01). Cow age only affected viable COCs (VIAB) (p ≤ 0.05), code one blastocysts (BC1) and BLAST (p≤0.01). Cortisol affected total COCs (COCsT), VIAB and total matured in vitro (TMIV) (p≤0.01), as well as CLI, BC1 (p≤0.01) and BLAST (p≤0.05). Insulin affected COCsT (p≤0.01), UNV (p≤0.05), denuded oocytes (DE) (p≤0.01), BC1 and code two blastocysts (BC2) (p≤0.01). Glucose affected all COCs variables (p≤0.01), except UNV and all embryo variables except BC2. HR affected COCsT, DE, TMIV (p≤0.01), CLI, BLAST and DEG (p≤0.05). RR affected COCsT, UNV, VIAB, CLI (p≤0.05), BC1, BLAST and DEG (p≤0.01). RT only affected DE, VIAB (p≤0.01) and BLAST (p≤0.05). The seasonal climatic year variation of Veracruz and changes in physiological and hormonal variables have diverse effects on the cumulus-oocyte complexes and embryos produced by RM and TM donors.

“…Furthermore, climate change is expected to affect cattle exposed to inter-annual climatic variability of grazing systems (Rust, 2019). In Tropical Milking criollo (TM) heifers, it was verified that Tmax before and RH after artificial insemination (AI) affected their gestation success (%) at first service (p ≤ 0.05; Rosales-Martínez et al, 2021). Importantly, TM cows have proved to be productive, more resistant to adverse climatic effects and to endo and ectoparasites, due -like adult animals-to their pigmented and thick skin, short and shiny hair and medium size, among other characteristics favorable to hot environments (De Alba, 2011).…”

The season of the year (ES), maximum temperature (Tmax) and relative humidity (RH) affect gestation success of Tropical Milking criollo (TM) heifers, but their effects on the gestation of TM cows are not completely known. The study aimed to determine the effects of environmental factors along with artificial insemination (AI) service and calving on the gestation success of TM cows. Data were collected during 14 years, 959 records of AI of 155 cows in three seasons: hot-dry (HD), hot-humid (HH) and fresh-dry (FD). The response variables were gestation success of cows at first service after first calving (GF), first calving first to fifth service (GS) and global gestation success (GG). Model effects were ES, Tmax and RH seven days before the AI (PRAI), the day of the service (DAI) and seven days after (POAI); and days open (DO), cumulative milk production (MP), number of service (NS) and calving number (CN). GF was analyzed with logistic regression, and GS and GG with generalized linear models. Over 50 % of estrus occurred in the HH season. Tmax affected GF b1 = -0.13 ± 0.07 (p ≤ 0.05) and GG b1 = -0.08 ± 0.04 (p ≤ 0.05) in PRAI. There were no effects of ES, RH, NS or MP on GF, GS and GG for PRAI, DAI and POAI (p > 0.05). DO affected GG in PRAI, DAI and POAI b2 = -0.005 ± 0.002 (p ≤ 0.01). GG were as close to 52.0 % for the three seasons. Although with no statistical differences in multiparous cows (p > 0.05), for NS maximum gestation were 60 % at first and third, and minimum 40 % at fourth services; for CN they were 60 % at fourth, and 40 % at sixth and seventh calving, respectively. TM cows are adapted to a hot tropical Climate and their seasonal changes, showing similar pregnancy frequencies among seasons.
