“…Nevertheless, this strategy implies that primiparous water buffaloes must have an especial management to prevent anestrus and infertility and thus guarantee a short conception interval. Primiparity and calving during long photoperiod season affect negatively the reproductive performance (Hassan et al, 2017;El-Tarabany, 2018;Nava-Trujillo et al, 2018) and this affects negatively the herd's profitability (Cicek et al, 2017;Hassan et al, 2017).…”

The aim of this study was to determine the effect of season and parity on water buffalo calving distribution throughout the year in Venezuela. A retrospective study analyzing records of 3,192 crossbred (Murrah/Mediterranean) buffaloes including 7,790 calvings was carried out in Venezuela. Two seasons were evaluated according to the length of the photoperiod: September-February (short photoperiod; autumn-winter) and March-August (long photoperiod; spring-summer). Parity order was categorized in parity 1, parity 2, parity 3, and parity 4. Photoperiod was shorter between September and February in comparison with March-August (11.81 ± 0.08 h/day and 12.42±0.08 h/day, respectively, p < 0.05). Percentage of calving varied between the two seasons (p < 0.05), and 63.7% (95% Confidence Interval (CI): 62.5%-64.9%) of calving occurred during the season of short photoperiod in comparison with that of the season of long photoperiod (36.3%, 95% CI: 35.1%-37.5%), and this effect was observed in all parities. The proportion of calvings during the short photoperiod season was greater as parity increased. The percentage of calving during the short photoperiod season was lower in primiparous water buffalo cows in comparison with that of multiparous water buffalo cows; conversely, the percentage of calving during the long photoperiod season was higher in primiparous water buffalo cows in comparison with that of multiparous water buffalo cows. Eight percent of water buffalo cows having their first calving in the long photoperiod season had the next calvings during this season. In conclusion, results confirm the seasonal reproductive behavior of water buffaloes with a concentration of calvings during the months with short photoperiod; this seasonality becomes stronger as parity increases; even though a small percentage of water buffalo cows has the ability of calving constantly during long photoperiod.

“…Khan et al [10] reported a decrease in economic return between 24 and 27% for water buffaloes with longer calving to conception interval; while the increase in the CI caused a decline in milk production of 2.1 kg per day when it increased from 365 to 635 days [9] and a negative correlation between CI and milk production per day of CI has been reported [18]. More recently, it was determined that the cost of each additional day of CI after 365 days, was 6.07 USD [23] and that each additional day over the average CI implies a decrease in earnings of 1.87 USD [24]. However, it is necessary to evaluate how reproductive strategies, like out-ofbreeding mating strategy, a practice to change the calving calendar, and increases milk offer during months with long photoperiod when water buffaloes have low reproductive activity [69], but this reproductive strategy produces a decrease of fertility and an increase of calving interval, affecting the economic performance of water buffalo systems.…”

This article aims to review both the economic impact of reproductive failures on the profitability of water buffalo systems and the effect of different factors on the reproductive performance of water buffaloes. Besides, an overview of various non-hormonal alternatives to improve reproductive performance is made. The optimal reproductive efficiency in water buffaloes implies calving to conception interval around 90 days to reach a calving interval of 400 days, with longer calving intervals having a negative impact on profitability. Reproductive efficiency is the consequence of the interaction of genetic and non-genetic factors, and the recognition of these factors by analyzing the reproductive information must be a priority. Although each factor's impact can be of greater or lesser magnitude depending on the conditions of each herd, some factors like nutrition, milk yield, body condition score, negative energy balance, parity, bull presence, low estrus intensity, and season can be considered high-impact factors. Not all factors are common among farms; therefore each farm must implement a program for the identification, control, and prevention of reproductive problems, especially during early lactation, to prevent a long anestrus; and when artificial insemination is used, so that it is done at the correct time with respect to the beginning of estrus to enhance fertility.

“…Currently, livestock farmers need to recognize non pregnant animal at the earliest opportunity so as to rebreed them at the very next opportunity. In developing countries like India, buffaloes are the most important dairy animal but they are suffering from problems related to reproduction such as long calving intervals, long open period and high incidence of repeat breeding (Jamuna et al, 2015;Cicek et al, 2017). These problems further aggravates by lack of early pregnancy diagnosis tools.…”

Interferon stimulated protein 15 is a well-known ubiquitin cross-reactive protein which is released from the ruminant uterus in response to interferon-tau (IFN-t) during conceptus implantation. This protein increases significantly during the early stages of pregnancy. Therefore, in the present study, Interferon stimulated gene (ISG15) coding region was isolated from buffalo blood at day 18 of pregnancy after artificial insemination. ISG15 was cloned in pET100 vector, overexpressed in E.coli and purified to investigate its properties. The protein was immunoblotted with mouse anti-His antibody to evaluate its characteristics after purification. To conclude, elucidation of protein properties in the prokaryotic system will provide an opportunity for understanding the basic biology of pre and post-implantation and development of a tool for early pregnancy diagnosis.
