The Effect of Dried Citrus Pulp, Dried Beet Sugar Pulp and Wheat Straw as Silage Additives on By-Products of Orange Silage

S. Arbabi, T. Ghoorchi and A.A. Naserian

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.
