Abstract
The study was conducted to determine the effect of treating cotton seed
cake (CSC) with three different ethanol concentrations on its ruminal
degradation characteristics of dry matter (DM) and crude protein (CP).
Three ethanol water solutions were prepared (v/v) at 50%, %,70% and
90% concentrations, then 500gm of CSC were soaked in excess of each
solution for an hour at 78°C. Each mixture was drained through cheese
cloth and the treated cakes (ETCSC) were air dried at room temperature.
The control was untreated CSC (UCSC). Nylon bags technique was
employed using two castrated calves.
All ethanol treated CSC showed significantly (P≤ 0.05) lower values
of the water soluble DM fraction (a) than UCSC with no variation among
the treatments. Degradation of the water insoluble fraction (b) was
significantly (P≤ 0.05) reduced by ethanol treatments the highest
protection was in 90% ETCSC and no variation was observed between
50% and 70% ETCSC. Treated CSC with 70% and 90% ethanol showed
significantly (P≤ 0.05) lower CP washing loss and degradation of the
water insoluble fraction (b) than that of 50% ETCSC and UCSC. The rate
constant (c) for (b) function was not affected by any of the three
treatments for both DM and CP. All the treatments significantly (P≤ 0.05)
reduced the effective degradability at three different rumen outflow rates.
Within treatments 90% ETCSC showed the strongest effect and no variation was found between the other two treatments.
