Animals should drink clean and adequate water every day. Providing enough and clean water is a challenge for human beings and animals. Therefore, innovative economical ways of using available water to take care of domestic animals. Types of animal waterer used by the community. Domestic animals are provided water in containers called waterers. Different domestic animals use different types of waterers. Some waterers are left open for the animals to drink water directly while others are automatic. The types of waterer used for watering animals in the community depends on the type of domestic animals kept. Large animals such as cattle, camel. Donkeys, sheep, goat and pigs use open containers and troughs constructed as part of their houses. Small animals such as rabbits and poultry use small containers cutout from jerrycans and hanged on the walls of their cages. Challenges of the existing animal waterers used by domestic animals in the community. Use of poorly constructed waterers-leads to inadequate water intake by the animals. Lack of skills in handling the waters. Poor placement of the waters. Poor usage by the animals leading to spillage and contamination of water. Provision of water to animals is a tiresome process discouraging community members from keeping domestic animals. Provision of less spacious waterers for large number of animals.
