Article Abstract
Sahiwal cow is Bos indicus which is an important dairy breed of tropical and sub-tropical region. Research on reproduction is rare in this breed. The objectives of the present study were to determine the effect of Ovsynch (OVS) versus prostaglandin F (PG) protocol on estrus response and its intensity, ovulation rate, timing of ovulation and pregnancy per artificial insemination (AI) in Sahiwal cows. Experimental cows (n = 80) were of mixed parity, lactating, suckled, ≥120 days postpartum with body condition score 3.08 ± 0.34 and 375-475 kg of body weight which were randomly assigned to receive either OVS (n = 46) or PG (n =34) protocol. Cows were inseminated twice at 12 and 24 h after second gonadotropin releasing hormone in the OVS group, and 72 and 84 h after administration of prostaglandin F in PG group, respectively. The results revealed that estrus response did not differ (P > 0.05) and was 87% in OVS and 78% in PG cows. Ovulation rate did not differ (P > 0.05) and was 50% in both, OVS and PG cows. The pregnancy per AI did not differ (P > 0.05) and was 43% in OVS compared to 31% in PG cows. It is concluded that estrus response, ovulation rate and pregnancy per AI of OVS protocol is the same as PG in Sahiwal cows.

Embryo transfer (ET) is a valuable reproductive technology in pigs, albeit its efficiency remains significantly lower than that of natural mating or artificial insemination (AI), owing to high embryonic death rates. Critical for embryo survival and pregnancy success is the placenta, which supports conceptus development through nutrient exchange, hormone production, and immune modulation. Alterations in placental development and function may therefore underlie the reduced efficiency of ET.

Vulvovaginal candidiasis (VVC), caused by the commensal pathobiont affects >75% of women, marring quality of life and incurring significant health costs. Estrogen (E2) activity is tightly linked to VVC susceptibility, and preclinical models employ E2 to establish vaginal colonization. Unlike most forms of candidiasis, VVC is not considered to be a condition of immune compromise.

Due to the growing environmental burden of endocrine-disrupting chemicals (EDCs), there is an increasing concern regarding the reproductive hazards posed by synthetic estrogens, particularly diethylstilbestrol (DES). However, the precise mechanisms by which DES disrupts uterine endocrine function and immune homeostasis leading to pregnancy failure remain unclear. Given that wild rodents serve as key reservoirs for zoonotic diseases such as plague, reproductive interventions targeting their pregnancy processes hold significant ecological implications for disease control.

This study evaluated the effect of the timing of Y-sorted sexed semen (SS) insemination after the onset of estrus on reproductive outcomes in beef heifers and examined the influence of AI sires and their sperm DNA fragmentation (%SDF) over time. Angus heifers (n = 718) from two locations were synchronised using a CIDR + Select-Synch protocol and blocked by age, body condition score, and reproductive tract score. Heifers expressing estrus were randomly assigned to AI at 12, 20, or 28 h post-estrus onset using SexedULTRA 4 M semen from one of three bulls.

There is a small number of studies describing the uterine biology of Bos indicus cows. We hypothesized that there is a transcriptional signature in endometrial epithelial cells 4 days after estrus (D4) that predicts the ability of the cow to remain pregnant/artificial insemination (AI). Brahman cows were submitted to an estrous synchronization protocol and AI.
