What are the welfare impacts for breeder ducks and how to mitigate the need for feed restriction, and the impacts of long-term housing on mental wellbeing?

Context and Relevance:

Breeder ducks are essential in the poultry industry, serving as the foundation for both meat and egg production. However, their welfare is frequently compromised due to common management practices such as feed restriction, which is used to control reproductive health, and the long-term housing systems that can lead to physical and psychological stress. These practices can result in issues such as chronic hunger, stress, reduced mobility, and stereotypic behaviors, ultimately affecting both the welfare of the ducks and farm productivity. Improving the living conditions and feeding regimes for breeder ducks is vital to ensure higher ethical standards in duck farming, with potential benefits including improved reproductive outcomes, better health, and overall farm sustainability. This research aims to identify and propose evidence-based strategies to address welfare concerns in breeder ducks, leading to more humane and productive farming practices.

Potential Research Approach:

Literature Review: Conduct a comprehensive review of scientific literature on the impacts of feed restriction and long-term housing on the welfare of breeder ducks. Focus on studies that highlight physiological and behavioral indicators of stress, nutritional needs, and housing conditions.

Field Studies: Perform observational studies in different duck farms to assess welfare indicators such as feeding behavior, activity levels, feather condition, and stress-related behaviors. Use physiological markers like corticosterone levels or immune function tests to gauge stress and health status.

Experimental Trials: Design controlled trials that test the efficacy of alternative feeding strategies (e.g., ad libitum feeding, slow-release feeds) and housing systems (e.g., enriched environments, free-range versus confined systems). These trials should assess outcomes such as stress reduction, physical health, reproductive success, and overall wellbeing.

Behavioral Assessments: Use standardized behavioral assessments to evaluate the mental and emotional wellbeing of breeder ducks. This may include tracking stereotypic behaviors, aggression levels, and social interactions under various housing and feeding regimes.

Stakeholder Engagement: Engage with key stakeholders including duck farmers, veterinarians, nutritionists, and animal welfare experts to gather practical insights on current practices and to discuss feasible welfare improvements. This engagement will help in developing recommendations that are economically viable and align with industry needs.

Additional Questions:

  1. What are the physiological and psychological impacts of prolonged feed restriction on breeder ducks, and how can alternative feeding regimes meet nutritional and reproductive goals without causing welfare issues?

  2. How do various housing systems (such as enriched indoor environments, outdoor access, or alternative confinement systems) affect the physical health, behavior, and reproductive performance of breeder ducks?

  3. What are the economic costs and benefits associated with implementing welfare-enhancing practices in breeder duck farming, and how can these practices improve long-term productivity and ethical standards?
