NR 39. Influence of molasses concentration, time and storage conditions on multinutrient blocks hardness

Resumo

In order to determine the influence of time, storage conditions and molasses level on the hardness of multinutrient blocks (BM); it were elaborated 72 blocks using urea 5 %, salt 10 %, mineral 8 %, hay 3 %, lime 10 %, molasses (30, 40 and 50 %) and the difference with corn meal. Three storage time (1, 14 and 28 days) and two storage packing forms (with and without packing), thereinafter it was measured resistance (kg/cm2) in a hydraulic press. It is used a totally random design with treatment arrangement in split plots in the time. The effect of the molasses level, storage condition, the packing-molasses interaction and the storage time on the resistance of the BM, resulted highly meaningful (P<.01), while the molasses-time interaction was meaningful (P<.05). It is conclude that resistance is directly proportional to the storage time, optimum to the 40 % of molasses and low ledger the storage condition without packing.
