The use of individual calving pens in modern farming is widely recognized as a good practice for promoting good animal welfare during parturition. This modeling approach has practical implications for dairy farmers who seek to maximize productivity and efficiency while minimizing costs. Our study contributes to the existing literature by proposing a novel approach that accounts for Markov dependence and linear regression in modeling lactation curves, which can lead to more accurate and reliable predictions. However, it is important to optimize the modeling process regularly before implementing these strategies to enhance productivity in dairy cows. Our results showed that lactation curve modeling using the proposed model could help set management strategies at the farm level. We compared the proposed model with three other models - quadratic model, mixed log function, and wood model - using various goodness of fit measures such as adjusted R2, root mean square error (RMSE), and Bayesian Information Criteria (BIC). Specifically, we develop a special type of Gamma Type Markov Chain Model that considers the first-order linear regressive property, which makes the model more realistic and reliable. In this study, we propose and examine a Markov-Dependent stochastic approach to modeling lactation curves in dairy cows, with the aim of developing a model that accurately fits lactation curves for a maximum number of lactations. The modeling of lactation curves is an essential aspect of formulating farm managerial practices in dairy cows. The experimental results proved that our proposed system could handle the problems of MOT and produce reliable performance. ![]() We also proposed a robust Multiple Object Tracking (MOT) algorithm for cow tracking by employing multiple features from the cow region. Deep features are extracted from recent cow images using a Convolutional Neural Network (CNN features) and are also jointly applied in the tracking process to boost system performance. As color and texture suitably define the appearance of an object, we analyze the most appropriate color space to extract color moment features and use a Co-occurrence Matrix (CM) for textural representation. ![]() In doing so, we simply exploited the distance between two gravity center locations of the cow regions. In the cow tracking stage, for successively associating each cow with the corresponding one in the next frame, we employed the following three features: cow location, appearance features, as well as recent features of the cow region. Cow detection is performed using a popular instance segmentation network. The proposed system processes images in separate stages, namely data pre-processing, cow detection, and cow tracking. ![]() In our approach, we applied a combination of deep learning and image processing techniques to build a robust system. Therefore, we propose a new method of using video cameras for recognizing cattle and tracking their whereabouts. ![]() However, identifying and tracking individual cattle can be difficult, especially for black and brown varieties that are so similar in appearance. As the body-attached sensors cause stress, video cameras can be used as an alternative. Conventionally, sensors have been used for detecting and tracking their activities. In modern cattle farm management systems, video-based monitoring has become important in analyzing the high-level behavior of cattle for monitoring their health and predicting calving for providing timely assistance.
