Etude de la composition chimique des noyaux de dattes en vue d’une incorporation en alimentation animale
The transformation of dates at industrial scale, generate by the processing agro food (paste of dates, vinegar, syrup) at small or large scale stones as waste of transformation. This study aims to evaluate the chemical composition of these stones for incorporation in animal feed. For this, we proceeded to chemical analysis of dates stones belonging to twenty cultivars in south-east of Algeria. The analysis focused on rates of dry matter, crude protein, crude fiber and neutral detergent fiber as adequate methods.
The statistical results revealed a highly significant difference between stones of the twenty varieties. The rate of dry matter is very high (up 93%) and fiber (NDF) reached the 92% suggest grinding mode of presentation of the food. The excessive wealth of stones on crude fiber (max19%) limits its inclusion in rations for ruminants because it limits the digestibility of the ration.
Date stones can be used in animal feed of productive zones, and especially for ruminants that tend to enhance cellulosic food but at limited rates.
