“…By importing semen rather than live animals, artifcial insemination (AI) technology maximises the utilization of outstanding males, the transmission of superior genetic material, the rate and efectiveness of genetic selection, and the introduction of new genetic material [8]. Because it is simple, economic, and successful, AI is the most important assisted reproductive technology in developing countries [9]. It is the most advantageous management technique available to cow producers, and it has been extensively employed to breed dairy cattle.…”

Artificial insemination (AI) is among the most effective reproductive biotechnologies that afford widespread propagation of genes carried by superior males. A cross-sectional study followed by a simple random sampling technique was conducted from December 2021 to May 2022 to assess the constraints of artificial insemination (AI) provision in and around Kacha Bira district, Southern Ethiopia, using a structured questionnaire. A total of 200 respondents were surveyed accordingly. In this study, the education level of farmers revealed no statistically significant difference P > 0.05 with the identification of time of insemination. Conception failure (62.5%), unavailability of artificial insemination technicians (7.5%), dystocia (3.5%), and both conception failure and unavailability of artificial insemination technicians (4.5%) were found to be the major constraints of AI service in the study area according to dairy cattle owners’ response and revealed a statistically significant difference P < 0.05 with AI service. Although statistically significant P < 0.05 , differences in AI service interruptions during both regular working hours and weekends and holidays were also observed. Among total respondents, 20.5% of dairy cattle owners got AI service at right time, but 79.5% of them used it at the wrong time. Regarding inbreeding problems, 77.5% of dairy cattle owners responded that there was no inbreeding problem and the remaining 22.5% of farmers indicated presence of inbreeding problem of which 10.5% and 10% had a perception that local breeds had low milk production and low genetic improvement than exotic breeds, respectively. On the other hand, 11.5% of dairy cattle owners responded that local breeds have a similar level of disease resistance to that of exotic breeds (11%). 48.5% of dairy farmers reported that bellowing is the most frequent sign that they used to detect heat followed by vulval discharge (23%) and mounting on other cows (10%). Majority (78.5%) of the dairy cattle owners interviewed were found to be not satisfied with the artificial insemination services. In general, different AI technicians and cattle and dairy cattle keeper-related factors constrain the AI service and its result in survey site. Therefore, smallholder dairy cattle owners should be trained sufficiently about the AI service strategies, usage, and proper management of dairy farms and the technical constraints should be avoided in order to provide AI service sufficiently.

“…Presently, Mithun is reared under the free-range system with no scientific intervention. At a slow pace, farmers are shifting from a free-range system of Mithun rearing to a semi-intensive system and demand for the implementation of assisted reproductive technology (ART) is escalating (Joshi et al 2020, Vikram et al 2023. Maximizing reproductive performance is a crucial prerequisite for the success of the Mithun production system.…”

The study aimed to assess the possibility of cervical mucus changes to predict ovulation time in Mithun. Experimental Mithuns (n=6) were estrus synchronized and cervical mucus was collected in different estrus phases from three consecutive estrous cycles (n=18). Cervical mucus colour, consistency, arborization pattern and cytology were evaluated. Plasma estradiol-17β (E2) and progesterone (P4) levels were determined during different phases of estrous cycles. Ovulation time and subsequent growth of the corpus luteum were determined using transrectal ultrasonography. Results indicated thick and moderate cloudy mucus with a typical arborization pattern in midestrus. Sticky caseous or white-coloured thick consistency cervical mucus was observed during metestrus in 66.66% (n=14) estrous cycles along with ovulation or ovulation occurring within the range of -3 to + 4.5 - +7.5 h after the appearance of white mucus. Cervical mucus cytology revealed percentages of polymorphonuclear neutrophils were significantly higher in metestrus. E2 concentrations reached the peak on the day of estrus and P4 concentrations were lower than 0.5 ng/mL. It was concluded that cervical mucus shows a typical arborization pattern in midestrus and the appearance of characteristic sticky caseous cervical mucus during metestrus can be used as a tool to predict ovulation time.
