“…The open field test (OFT) is one of the most commonly utilized tests to assess rodent depression-like behaviors in a novel open environment. 15 OFT uses an open box of 50 cm × 50 cm × 40 cm, and a camera is installed above it. The mice were placed at the same position facing the wall to move freely for 5 min.…”

“…The arena was cleaned with 80% ethanol (w/v) between each test. Videos were analyzed using a custom animal tracking software 25 . The primary variables assessed using tracking software included horizontal locomotive activity (distance traveled in cm) and exploratory behavior via center square entries (CSE) and center square duration (CSD).…”

Background Diet‐induced obesity (DIO) and psychological stress are significant independent regulators of gastrointestinal physiology; however, our understanding of how these two disorders influence the host‐microbe interface is still poorly characterized. The aim of this study was to assess the combined influences of diet‐induced obesity and psychological stress on microbiome composition and colonic gene expression. Methods C57BL/6J mice (n = 48) were subject to a combination of 22 weeks of Western diet (WD) feeding and a chronic restraint stressor (CRS) for the last 4 weeks of feeding. At the end of the combined intervention, microbiome composition was determined from cecal contents, and colonic tissue gene expression was assessed by multiplex analysis using NanoString nCounter System and real‐time qPCR. Results WD feeding induced a DIO phenotype with increased body weight, worsened metabolic markers, and alterations to microbiome composition. CRS reduced body weight in both dietary groups while having differential effects on glucose metabolism. CRS improved the Firmicutes/Bacteroidetes ratio in WD‐fed animals while expanding the Proteobacteria phyla. Significantly lower expression of colonic Tlr4 (p = 0.008), Ocln (p = 0.004), and Cldn3 (p = 0.004) were noted in WD‐fed animals compared to controls with no synergistic effects observed when combined with CRS. No changes to colonic expression of downstream inflammatory mediators were observed. Interestingly, higher levels of expression of Cldn2 (p = 0.04) and bile acid receptor Nr1h4 (p = 0.02) were seen in mice exposed to CRS. Conclusion Differential but not synergistic effects of WD and CRS were noted at the host‐microbe interface suggesting multifactorial responses that require further investigation.

Conventional method of counting animals is one of the most challenging tasks in livestock management; moreover, counting of animals in drone acquired imagery though promising, is more challenging in intelligent livestock management. In this paper, we apply state-of-the-art object detection model, Mask YOLOv7, for detection and counting of cattle in different scenarios such as in controlled (feedlot) environment and uncontrolled (open-range) environment. Mask mechanism was embedded into the backbone of the YOLOv7 algorithm (Mask YOLOv7) for instance segmentation of individual cattle object. We evaluate the performance of the model proposed in this study using IoU (Intersection over Union) threshold of 0.5, average precision (AP) and mean average precision (mAP). The results of the experiment conducted in this study show that the proposed model achieves an accuracy of 93% in counting cattle in controlled environment and 95% in uncontrolled environment. These results affirm the potential of the model, Mask YOLOv7, to perform competitively with any other existing object detection and instance segmentation models in terms of accuracy and average precision especially when the speed of object detection matters. Moreover, the research has potential applications in livestock inventory which helps in tracking, monitoring and reporting vital information about individual cattle.
