48 48 LOHMANN › MANAGEMENT GUIDE › EARLY MANAGEMENT Several stressors can impair the moulting process in birds, affecting their feather development and overall health. Here are some key stressors that can negatively impact the moulting process. Stressors affecting Moulting NUTRITIONAL DEFICIENCIES Protein & Amino Acids Inadequate levels of protein and essential amino acids can impair feather growth and quality. Vitamins & Minerals Deficiencies in vitamins (such as Vitamin A, D, and E) and minerals (such as calcium and phosphorus) can negatively affect feather development. Ensure birds receive a balanced diet with adequate protein, vitamins, and minerals to support feather growth. LIGHTING CONDITIONS Inconsistent Lighting Sudden changes in lighting duration or intensity can disrupt the moulting cycle. Inadequate Lighting Insufficient light can affect the bird's ability to regulate its biological processes, including moulting. Provide consistent and appropriate lighting conditions to support the moulting cycle. BEHAVIOURAL STRESS Aggression & Pecking Aggressive behaviour and pecking within the flock can damage feathers and cause stress. Overcrowding High stocking densities can lead to competition for resources, stress, and poor feathering. Manage flock behaviour to reduce aggression and stress, and provide adequate space for movement and perching. HEALTH ISSUES Diseases Infections and diseases can weaken birds, making it difficult for them to undergo a healthy moulting process. Parasites External parasites like mites and lice can damage feathers and cause stress, impairing moulting. Regularly monitor and address health issues and parasite infestations to ensure birds are healthy during moulting. ENVIRONMENTAL FACTORS Temperature Extremes Both high and low temperatures can stress birds, leading to poor feathering and delayed moulting. Humidity Levels Inappropriate humidity levels can affect feather quality and the overall health of the birds. Ventilation Poor ventilation can lead to respiratory issues and stress, impacting the moulting process. Maintain optimal temperature, humidity, and ventilation conditions to reduce stress.
