Valorisation of date-palm by-products (DPBP) for livestock feeding in Southern Tunisia. II-Characteristics and digestibility of DPBP-based silages

Khorchani T., Hammadi M., El Jani H., Genin D., Sakkal K., Abdouli H.

The present work aims at the conservation of DPBP as silage to enhance the use of readily available date-palm by-products, to expand the period of their use and to suggest complements or more balanced diets. Two types of silage were prepared. Silage 1 (S1) (chopped stems, wasted dates, wheat bran and urea dissolved in water). In silage 2 (S2), stems were replaced by chopped palm-leaves. Ingredients were mixed carefully and silages were preserved at ambient temperature in hermetic bags for 2 months. For in vitro digestibility studies, rumen liquors were taken from 3 animal species (sheep, goat and camel) killed in slaughterhouses. In order to determine in vivo digestibility of the two silages, 4 local kids were used during 2 successive periods. In vivo DMD of S1 were significantly higher than S2 and in vivo organic matter digestibility (OMD) were not different for the two silages. This technique seems to be appropriate for DPBP conservation and enhancement use.
