Effects of additives on chemical composition, degradability coefficients and ruminal-intestinal disappearance of dry matter and crude protein of laboratory ensiled olive cake
نویسندگان
چکیده مقاله:
The chemical composition, degradability coefficients (in situ) and ruminal-intestinal disappearance(mobile bag procedure) of dry matter (DM) and crude protein (CP) were evaluated for olive cake (OC)silages treated (DM basis) with additives as follows: (1) untreated OC, (2) OC + 0.5% urea, (3) OC + 0.4%formic acid, (4) OC + 8% molasses, (5) OC + 0.5% urea + 8% molasses, (6) OC + 0.5% urea + 0.4% formic acid, (7) OC + 8% molasses + 0.4% formic acid and (8) OC + 8% molasses + 0.4% formic acid + 0.5% urea. The highest reduction in cellulose and ADF content was found for treatment 8 (120 and 117 g kg-1 DM, respectively), as compared with the raw material (not ensiled). Taking into consideration the chemical composition, pH values, and the general appearance of silages, ensiling of OC with additives preserved well and enhanced the nutritive value of olive cake. Ruminal maximum potential degradability of DM (a+b), effective and rapid degradability and rate of degradation of treatment 8 were higher than others. The same trend was found for CP except fraction “a” which was highest for treatment 6. Mean ruminal DM (P

Two experiments were conducted to evaluate the effects of microwaving, autoclaving (moist heating), and roasting (dry heating) on gas production parameters and in situ rumen degradability of soybean meal (SBM). SBM was treated by roasting at 140℃ for 30 and 60 min, and at 160℃ for 30 and 60 min, autoclaving at 121℃ for 20 min, and microwaving for 2, 4, and 6 min. A gas production trial...

The aim of the experiment was to determine the effect of different dry matter content and addition of silage inoculant on the ruminal protein degradability. Alfalfa herbage was collected from two cuts and the fresh matter was sampled two times during each cut (with different dry matter content). During the preparation of experimental micro-silages, the chopped forage was treated with a microbia...
