In animal farming, timely estrus detection and prediction of the best moment for insemination is crucial. Traditional sow estrus detection depends on the expertise of a farm attendant which can be inconsistent, time-consuming, and labor-intensive. Attempts and trials in developing and implementing technological tools to detect estrus have been explored by researchers. The objective of this review is to assess the automatic methods of estrus recognition in operation for sows and point out their strong and weak points to assist in developing new and improved detection systems. Real-time methods using body and vulvar temperature, posture recognition, and activity measurements show higher precision. Incorporating artificial intelligence with multiple estrus-related parameters is expected to enhance accuracy. Further development of new systems relies mostly upon the improved algorithm and accurate data provided. Future systems should be designed to minimize the misclassification rate, so better detection is achieved.

This meta-analysis aimed to evaluate the efficacy of automated activity monitoring (AAM) in detecting estrous expression and ovulatory status in cows during the voluntary waiting period (VWP). A comprehensive literature search was conducted in PubMed, ScienceDirect, and Google Scholar using specific search terms. Inclusion criteria focused on studies that assessed estrous expression within the VWP using modern AAM systems alongside blood progesterone (P4) measurements.

In South American Camelids (SAC), determining a suitable time point for mating poses challenges as females ready for conception do not show estrus signs or behavioral changes. Therefore, the applicability of measuring sex steroids in milk and vaginal cytology as non-invasive methods for monitoring ovarian activity was investigated.Samples were collected from a total of 10 alpacas (A) and 9 llamas (L) over a period of 4 weeks following parturition.

Buffaloes play a vital role in Bangladesh's livestock sector, contributing significantly to the nation's milk and meat production. However, their productivity remains below potential due to limited genetic capacity, poor reproductive performance, and inadequate health and management practices. This review critically synthesizes findings from scientific literature, field studies, and national reports to assess the status of buffalo production, reproductive efficiency, genetic improvement efforts, and disease management strategies in Bangladesh.

This study aimed to investigate the associations among early postpartum estrous characteristics (EPEC) and reproductive outcomes in dairy cows fitted with automated monitoring devices (AMD). We hypothesized that EPEC within 41 DIM reflects cows' physiological resilience and serve as predictors of subsequent fertility. Furthermore, we trained and tested algorithms predicting the fertility potential of cows and compared the reproductive performance of cows classified as low, moderate, and high fertility.

Salivary fern patterns (SFP) offer a simple, non-invasive, and cost-effective alternative to conventional estrus detection methods, addressing challenges such as silent heat, inaccurate heat detection, and improper timing of artificial insemination (AI). This study evaluated the utility of SFP in determining best timing for AI and its association with conception in buffaloes. Two experiments were conducted.
