ABSTRACT
This paper determined the soluble carbohydrates, the “in vitro” dry matter digestibility (IVDMD) and the organic acids of three pearl millet genotypes silage, after 1, 3, 5, 7, 14, 28 and 56 days ensiling in PVC laboratory silos. A great difference was found among soluble carbohydrate contents in green forages and BN-2 genotype presented the higher value (8.33%). There was a high utilization of this fraction throughout the fermentation process, and after the fifth day the three pearl millet genotypes silage showed similar values (P>0.05). After 56 days ensiling, the latic, acetic and butiric acids mean values were 6.72%, 1% and 0.02%, respectively. The in vitro dry matter digestibility was not modified throughout the fermentation process. The IVDMD ranged from 52.93 to 57.18% in green forage and from 51.78 to 55.36% in silage in the last evaluation period (day 56 ). According to the evaluated parameters, the three pearl millet genotypes can be suggested for silage making.
