Abstract:
Silage of orange by-products (mainly the peel) is tested
in micro-silos, carrying out and checking 4 treatments: addition of 5%
(fresh weight) Dried Citrus Pulp (DCP), of dried sugar beet pulp (DSP),
of Wheat Straw (WS) in 2 different times (0, 72 h). Silages were assessed
using both method of appearance evaluation and method of DM, pH. CP, NDF,
ADF, TVFA, WSC, aerobic stability and DM degradation each of treatments
were determined after 60 days. Treated silages had better appearance quality
than the control silages in Flieg`s method. All of the silages had good
and very good degrees in the method based on DM, pH. The treated silages
had no differences pH compared with control. The control group that was
sealed immediately, had lower DM content compared with treated silages
(p<0.05). Treated silage with WS had the highest content of ADF (p<0.05).
NDF in the control silage and the treated silage with DCP was lower than
the others (p<0.05) and amount of CP in the treated silage with DSP
was more than others (p<0.05). Time of ensiling and treatments made
no difference in TVFA content of silages. WSC in treated silage with DCP
and DSP were more than other samples (p<0.05). There are significant
differences for the concentration of DDM, DE, ME, TDN in the silages.
Treated silages with WS had lower contents than the others (p<0.05).
The wilting before ensiling caused an increase in aerobic stability in
treated silages compared with untreated silages (p<0.05). Application
of WS additive resulted the lowest degradation dry matter among the experimental
additives (p<0.05). Overall, in our experimental conditions, citrus
pulp silage seemed to be convenient for producing animals.
