The quality of the cell wall fraction content of two silage by-products was assessed together with their different mineral composition. Various treatments to test possible improvements in the ensilage of canning industry artichoke and orange by-products were compared with the addition of different additives. Three treatments were assessed: sodium chloride (25 g kg-1), dehydrated beet pulp (62.5 g kg-1), formic acid at 4% in doses of 62.5 ml kg-1. A fourth batch acted as a control group. Samples were analysed for their nutritive characteristics. After a 100-day ensilage period the results showed that the use of the additives in the given doses did not significantly improve the quality of the silage, although the composition of the sodium chloride batch appeared to be better.
