Aprovechamiento del substrato degradado por pleurotus ostreatus en la alimentación de ovinos y en la producción de vermicomposta
The potential of the substrate biodegraded by Pleurotus ostreatus (SMS) in sheep (Criollo "Chiapas" breed) feeding was evaluated. The SMS (pH = 8.1 ± 0.45) utilized in this study was a mixture o f corn cobs (without grains) and corn stubble, which was treated by immersion in alkaline water prior to inoculation with P. ostreatus. The treatments (Phase I) were: Ti = 100% Kikuyu grass (K), Pennisetum clandestinunr, T2 = 80% K + 20% de SMS; T3 = 60% K+40% de SMS and T4 = 40% K+60% SMS; in each o f the four treatments, the sheep were given 100 g o f concentrated commercial feed (CF,18% protein). In Phase II, the same treatments were tried as in Phase I, but the feed was enriched with 20g o f molasses (M), 6g o f urea (U), 3g o f mineral salts (MS) and 200g o f CF. Intake, digestibility, nitrogen balance (NB), weight gain and wool growth were evaluated. In Phase I, no difference was found (P>0.5) amongst the treatments for intake, in vivo digestibility (IVD) and NB in most o f the nutrients; except in the intake o f crude protein (CP) and fiber-bound nitrogen (N-f), where Ti (89.52 and 5.23 g d-1 respectively) and T2 (80.57 and 4.8 g d -1 respectively) were greater than T4 (51.19 and 3.31 g d -1 respectively; P<0.05) and the intake o f lignin (L) was greater (43.50 g d-1) in T4 with respect to Ti (33.28 g d-1; P<0.5). The IVD of the CP, N -f and NDF were higher (11.69, 0.56, and 40.78 g d-1 respectively) in Ti than in T4 (4.93, 0.16, and 28.58 g d-1, respectively; P< 0.05).
