Parâmetros físicos da qualidade de formulações comerciais para bovinos leiteiros

Abstract

Feeds sold in pellet form are a very widespread processing in the animal feed chain. This process improves the use of food, increases the digestibility characteristics and ensures the best animal performance. To guarantee a quality product, the entire production process must be monitored, ensuring that it is within the quality standards and improvements in the use of food, for this it must be ensured that the parameters of the pellet guarantee index (PDI) and Percentage of Fines (FOB) associated with Humidity correspond to the parameters followed by the company. For this experiment, four samples of each type of pellet feed were used, these denominated as BocLac 22, BocLeite 22 AE, BocLeite 22 TOP and BocLeite 25 TOP, which were sold in bulk form over a period of three months. The aim of this work was to evaluate the physical quality parameters of pellets from four pelleted formulations aimed at dairy cattle and the interactions between these results. There were no differences between the valid parameters, but pelleted formulations such as BocLac 22 present a greater range of variation between the results of the repetitions, on the other hand, the BocLeite 22 AE base has a smaller amplitude in relation to its repetitions. Therefore, the resulting rations expected by the company, within the quality standards, but with greater variation in the results of repetitions in relation to sources.
