A Novel YOLOv6 Object Detector for Monitoring Piling Behavior of Cage-Free Laying Hens

May 12, 2023 | mdpi.com | Ramesh Bahadur Bist |Sachin Subedi |Xiao Yang |Lilong Chai

4. DiscussionIn the present study, we aimed to evaluate the performance of various YOLOv6 models for the detection of PB in poultry. The PB is a serious concern in commercial poultry farming, as it can lead to decreased welfare [,,] and other negative consequences. In addition, PB has been linked to floor eggs [,] and FELB [], so accurate detection can also help reduce these issues.
Effective Strategies for Mitigating Feather Pecking and Cannibalism in Cage-Free W-36 Pullets

May 7, 2023 | mdpi.com | Ramesh Bahadur Bist |Sachin Subedi |Xiao Yang |Lilong Chai

Abstract:Pecking is one of the most concerning poultry welfare issues in the layer houses, especially in the cage-free (CF) housing system. Pecking behavior may lead to severe feather pecking (SFP) and cannibalism when birds feel frustrated, stressed, and dominant over other birds. Since pecking is caused by multi-factorial problems (e.g., hormonal influence, environment, dietary composition, and genetic differences), it is very important to find optimal strategies for reducing pecking damage.
Effects of Perching on Poultry Welfare and Production: A Review

Mar 30, 2023 | mdpi.com | Lilong Chai |Prafulla Regmi |Ramesh Bahadur Bist |Sachin Subedi

Abstract:Perching is one of the essential natural behaviors for avian species. Providing an optimal perching design (e.g., shape, dimension, and materials) for commercial poultry production is critical for maintaining bird health, welfare, and production efficiency. This review paper summarized poultry perching studies and discussed the relationship between perch design, bird welfare, and production efficiency.
