Uso de co-produtos dietéticos no desempenho de coelhos: uma revisão

Abstract

The Brazilian rabbit farming is in growing expansion, however, the cost with feeding are high. To ensure economic viability in the rabbit sector, research has been developed related to the use of alternative foods and co-products, aiming to reduce diet related costs. Therefore, the objective of this literature review was to approach the use of co-products and alternative foods in the diet of rabbits, focusing on their effect on animal performance. The period of publication of articles estimated for the searches was between 2010 and 2022. The availability of co-products and alternative foods is wide, however, when choosing these, factors such as source, quality and chemical-bromatological composition and region must be taken into accout. These factors are related to possible deleterious effects that can lead to reduced animal performance. Once chosen, it is expected that the dietary inclusion of such foods will promote better intestinal health of the animals, and consequently greater weight gain, lower feed conversion and influence the cost of production of the diet. It is conclude that there is a diversity of ingredients available to be included in diets for rabbits. However, it is necessary to carry out continuous studies to efficiently determine the inclusion levels per phase, as well as the identification of anti-nutritional factors and negative effects present in certain foods.
