Table 8: Morning and evening milk yield and composition for six lactating cows during the recording period. This is why there is high NDF, ADF, and ADL content in the current forages. Forages gradually lose their nutritive value when the storage conditions are not good [19; 20]. When forages lose leaves, the proportion of stems increases and ADL and NDF content is high [19; 21]. Forage conservation determines its quality and the way farmers store the forage contributes to an increase in the lignin content and a decrease in forage digestibility. In those conditions, forages cannot meet the requirements of livestock, especially during the dry season [22].
