“…The peri‐parturient phase has a significant impact on the health and subsequent performance of dairy animals since they undergo significant metabolic and physiological changes during this time (Alharthi et al., 2021 ; Piccione et al., 2012 ). Negative energy balance (NEB) during early lactation is one of the common physiological causes of oxidative stress and health concerns in dairy animals (Elsayed et al., 2019 ; Saqib et al., 2018 ; Zhao et al., 2019 ). Dairy cows adjust to multiple hormonal and metabolic changes associated with the end of pregnancy and the start of lactation during the transition period (Colakoglu et al., 2019 ).…”

The aim of this study was to determine the metabolic status, stress and ovarian activity through progesterone profile in dairy buffalo as influenced by post‐partum days, body condition score (BCS) and lactation number. A total of 45 dairy buffaloes were involved and divided into three factors based on their BCS (2.5, 3.0 and 3.5, respectively), lactation number (1, 2 and 3, respectively), and post‐partum intervals (14, 28, 42 and 56, respectively). Based on findings, from day 14 to day 56 after parturition, blood glucose, cholesterol and triglyceride levels increased significantly (p < .01), while malondialdehyde (MDA) and cortisol levels decreased significantly (p < .05) on day 56 of the trial. With increased BCS levels, milk yield, blood metabolites and progesterone improved significantly (p < .05), whereas stress indicators decreased significantly (p < .01). Blood metabolites, progesterone and milk production were significantly (p < .01) higher and stress indicators (MDA and cortisol) were significantly (p < .01) lower in lactation stage. Buffaloes with a greater lactation stage and growing post‐partum stage had better blood metabolite and progesterone concentrations and less stress. It was concluded that better BCS and increased lactation stage have significant impact on milk yield, stress reduction and restoration of ovarian activity in buffaloes during post‐partum period.

“…The mechanism through which negative energy balance affects reproductive performance is complex and has not been well studied in water buffaloes. Elsayed et al [145] observed that buffaloes with delayed postpartum ovarian activity (> 45 days postpartum) and consequently with a longer conception interval (170.50±16.20), had lower body condition and lower levels of IGF-I, glucose, albumin, SOD and GSH, as well as higher levels of NEFAs and BHB during postpartum than those with an early restart of ovarian activity (< 45 days postpartum) and a shorter interval to conception (121.60±15.00). In addition, the levels of NEFAs and BHB were positively correlated with the interval to first ovulation postpartum, while the body condition score and levels of IGF-I, albumin, SOD, and GSH were negatively correlated [145].…”

In addition, the levels of NEFAs and BHB were positively correlated with the interval to first ovulation postpartum, while the body condition score and levels of IGF-I, albumin, SOD, and GSH were negatively correlated [145]. These findings indicate that restriction of dry matter intake and the increase of energy demand of milk synthesis during the postpartum period leads to low glucose levels and consequently insulin, that affects the expression of receptors for growth hormone (GH) in the liver, this implies a low hepatic synthesis of IGF-I and an increase in GH levels and excessive lipolysis.…”

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.
