Ensiling fresh dairy cattle manure (CM), corn stover, molasses (MO) or bakery by-products (BBP), as a viable method to produce good quality silage was evaluated. Silages composition was as follows: 1) molasses silage: CM, corn stover and molasses; and 2) BBP silages: CM, corn stover, and BBP. A low (250 g/kg dry matter) and a high (500 g/kg dry matter) level of CM with MO or BBP silages were incorporated in diets, and compared with a control diet (without CM silage) in lambs. There was a linear increase (P < 0.01) of dry matter (DM) intake and a quadratic increase of fiber digestion. Linear decrease (P < 0.05) in acetate to propionate ratio was observed with increased concentrations of MO or BBP in silages. Increasing MO silage caused a linear reduction of N intake and retained N, as well as a linear increase of fecal N. There were quadratic effects of BBP silage level on N intake, urine and retained, being the lowest values observed with the low level of BBP silage. Addition of BBP silages (250 or 500 g/kg DM) bring higher DM intake and total tract digestion of fiber, as compared to those diets without CM silage.
