Efeito da quantidade fixa ou variável de leite e do uso de aditivos sobre o desempenho de cabritos lactentes

Abstract

This study was carried out in the sector of goat culture of the UFRRJ where two experiments were performed to evaluate some nutritional strategies to raise more economically the goat kids. In the first experiment the daily weight gain (DWG) was measured in four animals groups that received goat milk, cow milk, cow milk plus soybean oil and cow milk plus soybean oil and Saccharomyces cerevisiae. In this study, the DWG and the weaning age was, respectively, 0,162, 69; 0,161, 72; 0,156, 78 and 0,156, 77. All results were satisfactories and did not differ statistically; but the use of the pure cow milk was the more economic treatment. The second experiment compared the traditional scheme of feeding (1,5 kg milk/day) and the milk offered according the energetic needs of animals (variable amount of milk/day). The DWG did not differ among the treatments (0,140 and 0,156 kg/day) and the weaning was done at 76 and 79 days, respectively. The group that received milk based on energetic demands given an economy of 20 L/animal. From this experiments, is possible to conclude that the goat kids can be raised on pure cow milk and the daily amount of milk can be offered based on its energetic needs.
