Hygiene & Sanitation
As soon as the previous flock has been cropped/depleted, the house and equipment must be thoroughly cleaned and disinfected. Allow the house to remain empty for a minimum of two weeks before the next flock arrives. This reduces the buildup of disease-causing organisms. After the birds have been removed from the house, remove all equipment and dampen the ceiling, wall, and litter with water. This minimises dust during litter removal. Remove all old litter and dispose of it at least 1.5 km from the farm.
Do not store it on, or spread it near the flock house, as it can re-contaminate the clean house. To minimize the chances of disease transmission, all unused feed should be disposed of, and not stored for the next flock. Only feed in bags that are stored separately from the house can be kept. Wash the house with water and soap. Start with the roof, the walls and then the floor, in that order.
Allow the house to dry before spraying with disinfectant solution, again starting from the roof. Wash and disinfect all equipment from the house. Repair and maintenance of equipment should also be carried out during this time. You can also apply effective broad-spectrum disinfectant through a pressure washer with a jet nozzle. Thoroughly soak all the interior surfaces and equipment, working from top to bottom.
After disinfection, bio-security controls at house entrances must be reinstated. Once the house is dry, place four inches of litter material and put back all the clean and disinfected equipment into the house. Common types of litter are wood shavings, straw, rice and coffee husks. Good litter should insulate the floor and absorb moisture from chicken droppings. Prepare the brooder area at least 24 hours before the chicks arrive (see brooder area arrangement below).
To monitor the effectiveness of the sanitation programme, a visual inspection and microbial culture are suggested. One can also use quantitative laboratory tests. Sterilization of the facilities is not realistic, but microbiological monitoring can confirm that undesired organisms such as salmonella have been eliminated.
