“…One difficulty that dairy production has long had to deal with is the inadequate detection of estrus, which results in low reproductive yield (Verma et al 2014). Behavioral manifestations have played a vital role in identifying this condition, but female buffaloes only express these characteristic behaviors when a male is close by (Selvam and Archunan, 2017). Several proposals have been put forth as means of identifying estrus in individual female buffaloes (Selvam and Archunan, 2017), including biochemical and gynecological approaches, and close observation of visual parameters (e.g.…”

The objective of this review article is to discuss and analyze the most important scientific findings from studies of vascular microcirculation in the river buffalo using infrared thermography (IRT), as well as the thermal windows utilized with this species. The goals are to define the scope and areas of opportunity for IRT use in evaluating physiological processes and identifying potential applications in reproductive events associated with andrological traits in males and the detection of estrus and udder health in females. IRT has allowed the development of diverse perspectives regarding the comparative physiology of events like thermogenesis, peripheral blood flow, respiratory physiology, and mechanisms that reduce body temperature. The case of the river buffalo is no exception. According to the information analyzed, the temperatures of the orbital area, muzzle, and vulva have proven efficient for evaluating thermal comfort, a particularly important aspect of this species given its limited thermoregulating capacity and constant exposure to extreme temperatures. Evaluating scrotal temperature has been revealed as an appropriate tool for evaluating semen quality, while the surface temperature of the udder is useful in assessing mammary development in female buffaloes, two aspects of great zootechnical importance. In future studies, IRT will play a fundamental role in enhancing our understanding of the river buffalo's mechanisms of vascular microcirculation, with applications in productivity and behavior.

“…Since the duration of heat in cows is only 48 hours and the estrus cycle only occurs every 21 days (Selvam & Archunan, 2017;Johnson, 2016), knowing the signs of heat and the physical and behavioral manifestations of cows is critical to successful insemination (Hansen, 2013). Since AI services are not free, not being able to inseminate successfully can result in paying for inseminators more than once, thus posing a financial loss to farmers.…”

Cattle farming is important for the socio-economic development of Rwanda, representing 12% of the national gross domestic product (GDP). In general, livestock production is a primary source of income. Recognizing the importance of cattle, the Government of Rwanda introduced the Girinka program in 2006 to reduce poverty and childhood malnutrition by providing poor people with dairy cows. The sustainability of the Girinka program relies on the successful breeding of cattle. Artificial Insemination (AI) is a method that can enhance cattle reproduction, but many Girinka beneficiaries did not have the requisite knowledge to maximize the success rate of AI by tracking the estrus cycle (heat detection) of their cattle.This project aimed to study the effect of training Girinka farmers on heat detection using the International Livestock Research Institute (ILRI) materials on cattle AI. A two-day training was provided to 74 Girinka cattle farmers. The cattle AI success rate and the farmers’ knowledge of heat detection were measured.The overall knowledge of farmers on cattle estrus cycle significantly increased from 37.16% pre-intervention to 92.34% post-intervention (P=0.008). The AI success rate significantly increased from 44% pre-intervention to 58.7% post-intervention (P<0.001).The study showed that by providing an evidence-based training to farmers on heat detection and estrus cycle in cattle could increase the success rate of AI. The same training is recommended for all Girinka beneficiaries in Rwanda. Longer term follow-up and scaling-up of the project should be considered to maximize the benefits.

“…This leads to difficulty in estrus detection, improper insemination time, and conception failure in buffaloes ( Sharma et al, 2008 ; Das and Khan, 2010 ). In addition, various estrus detection tools, such as teaser bull parading, tail painting, KaMar heat mounting detector, behavioral monitoring using a closed circuit television, and activity monitor using a pedometer, were used in buffaloes that are not very efficient since their sensitivity and specificity vary widely ( Selvam and Archunan 2017 ). Therefore, discovering estrus biomarkers in easily accessible body fluids such as saliva is of utmost importance for developing an easy, reliable, and accurate estrus detection method for buffaloes.…”

Comparative Proteome Profiling of Saliva Between Estrus and Non-Estrus Stages by Employing Label-Free Quantitation (LFQ) and Tandem Mass Tag (TMT)-LC-MS/MS Analysis: An Approach for Estrus Biomarker Identification in Bubalus bubalis

Accurate determination of estrus is essentially required for efficient reproduction management of farm animals. Buffalo is a shy breeder and does not manifest overt signs of estrus that make estrus detection difficult resulting in a poor conception rate. Therefore, identifying estrus biomarkers in easily accessible biofluid such as saliva is of utmost interest. In the current study, we generated saliva proteome profiles during proestrus (PE), estrus (E), metestrus (ME), and diestrus (DE) stages of the buffalo estrous cycle using both label-free quantitation (LFQ) and labeled (TMT) quantitation and mass spectrometry analysis. A total of 520 proteins were identified as DEPs in LFQ; among these, 59 and four proteins were upregulated (FC ≥ 1.5) and downregulated (FC ≤ 0.5) during E vs. PE, ME, and DE comparisons, respectively. Similarly, TMT-LC-MS/MS analysis identified 369 DEPs; among these, 74 and 73 proteins were upregulated and downregulated during E vs. PE, ME, and DE stages, respectively. Functional annotations of GO terms showed enrichment of glycolysis, pyruvate metabolism, endopeptidase inhibitor activity, salivary secretion, innate immune response, calcium ion binding, oocyte meiosis, and estrogen signaling. Over-expression of SERPINB1, HSPA1A, VMO1, SDF4, LCN1, OBP, and ENO3 proteins during estrus was further confirmed by Western blotting. This is the first comprehensive report on differential proteome analysis of buffalo saliva between estrus and non-estrus stages. This study generated an important panel of candidate proteins that may be considered buffalo estrus biomarkers which can be applied in the development of a diagnostic kit for estrus detection in buffalo.
