Abstract
There was evaluated the nutritional composition of the Hay of Foliage of Yucca, (HFY) (Manihot esculenta Crantz), var. MPER183, with base in the comparison of two (2) methods of Dried: natural, (ND) and Artificial, (AD). In each of them, there were in use two (2) loads (charges) of Green Foliage (GF) (7.5 and 15.0 K.m-2) and three (3) cutting frequencies. The FV was harvested every 14 days, starting at 16 and 18 weeks for the ND and the AD respectively. The content of dampness was evaluated from 0 to 48 hours in the ND and in the AD, every two hours (0 at 8 hours). The AD realized in a dryer of fixed cap divided in compartments that it works which generates warm air forced to (40°C), using for it, an engine driven with propane as combustible gas. There measured the Dry Matter (MS) to 60°C for 48 hours. The contents of dampness, of nutritional composition, and of hydrocyanic acid (HCN). Were analyzed by statistical models of differentiated variance analysis, according to the processes in evaluation, by means of randomized completely design by different arrangements each one. The results indicated the dried method,load and cutting frequency did not affect significantly the nutritional composition of the HFY. In agreement to the results of variance analysis between the dried methods and with the exception of the MS, significantly differences did not observe for the variables organic matter (OM), crude protein (PC), detergent neutral fiber (DNF), detergent acid fiber (DAF), hemicellulose, cellulose and lignin. For the AD, the total and liberated HCN was higher in relation than the ND. The unitary costs of production for K of HFY, were 61.5 %, major with the AD (COP. $ 221), in relation with the ND (COP. $ 136).
