Abstract

OJEDA, F; CACERES, O; MONTEJO, I  and  MARTIN, G.J. Study of the action of the Sorbial probiotic on the nutritional indicators of orange pulp conserved with different absorbing materials. Pastos y Forrajes [online]. 2008, vol.31, n.3, pp.1-1. ISSN 0864-0394.

With the objective of evaluating the effect exerted by the Sorbial probiotic on the nutritive value of citrus pulp silages conserved with different absorbing materials, a study was carried out with sheep consisting in evaluating first the silage under study and afterwards the same treatment, with Sorbial probiotic (20 g probiotic/animal/ day). The treatments were: a) orange pulp (OP); b) OP + 10% sugarcane bagasse; c) OP + 20% pre-wilted mulberry (40% DM); and d) OP + 10% bean straw. In the silages dry matter, organic matter, crude protein, crude fiber, pH and N-NH3/Nt were determined. In order to guarantee the maintenance needs of the animals in crude protein, 1 kg of fresh mulberry was supplied; while the silages were supplied ad libitum. The nutritive value was determined through intake and digestibility percentages of organic matter, crude protein and crude fiber. Dry matter and crude fiber increased with the incorporation of the absorbing materials. The integral evaluation of the treatments indicates that the probiotic supply increased the ration intake in 5 g DM/kg P0,75, as well as the ingestion of organic matter (+ 5,6 g),crude protein (+ 0,8 g) and digestible crude fiber (+ 3,1 g). The use of probiotic in diets of orange pulp mixed silages is concluded to improve the nutritional indicators and zootechnical responses depend on the absorbing material used.
