Utilização de sucedâneo na dieta líquida de bezerros leiteiros

Abstract

Currently, dairy farmers are looking for higher animal performance and cost reduction, with several alternatives being used. Among the stages of production of dairy animals, the one that most arouses attention is the period in which the calves are being suckled, due to the fact that these animals are still fragile and are more susceptible to diseases. An important factor during the lactation phase is related to what will compose the liquid diet supplied to the calves, because depending on the product used, there can be a considerable cost reduction without affecting the animals' performance. In this context, the substitute is an alternative product that can be used instead of whole milk, however for its use to be successful it is important to consider which breastfeeding system will be used, the amount to be provided, its composition and concentration of total solids in the diet. The objective of the present work was to analyze the use of substitutes in suckling calves, as well as to analyze the forms of supply and the performance of the animals. In view of the review carried out, it can be concluded that the success of using substitutes does not have a fixed rule, as this will depend on factors related to the composition of the product, costs and the reality of each dairy property. Thus, it is also important to provide technical support to make the most appropriate decision in each situation.
