It is based on modern, environment friendly technologies which do not use synthetic chemical substances (fertilizers, pesticides, drugs, growth enhancers, etc.), but use their substitutes instead. Ecological rabbit breeding is a novelty in Lithuania; however, the observations prove that the number of those willing to run such farms is increasing. The conditions of rabbit keeping must be as close to natural as possible to assure that the wellbeing and health requirements for the animals are fulfilled. Rabbits must have a possibility to move freely, satisfy their instincts. Goal of research. The research aims to study the digestibility of nutrients in rations used for feeding rabbits with ecological feedstuffs. Method of research. The research has been carried out at the vivariums of Lithuanian Veterinary Academy using New Zealand rabbit breed. To study digestibility 3 groups were formed, 10 rabbits aged 60days were selected from each group. The rabbits were kept in individual cages and had sufficient of water. The same feedstuffs as on ecological farms were used. The research consisted of the following stages: 1. Adaptation (duration – 3 days); 2. Preparatory stage (duration – 5 days); 3. Collection of faeces and stale (duration – 5 days). Review of research data. The crude protein and raw fat in ration perform a specific function of life-support and production, in case of...
