“…Silage ammonia N was higher in timothy than in ryegrasses in both years. However, ammonia N was less than lOVa of total N in all cases which indicated that proteolytic activity was at a minimum in the silages (Haigh and Hopkins 1977).…”

The effect of chemical composition of silages on in vitro gas fermentation profiles in rabbits was examined. The study was performed using 7 silages: beans (Phaseolus vulgaris), faba bean (FB, Vicia faba), common vetch (CV, Vicia sativa), ryegrass (Lolium perenne), barley (B, Hordeum vulgare), barley with common vetch (BCV) and barley with faba bean (BFB). We used 3 New Zealand White (NZW) rabbits as donors of caecal content in each incubation run (n=3). Data were analyzed in a completely randomized experimental design. The CV silage showed higher values of crude protein (CP), followed by FB and bean silages (P<0.001). Barley silage had the lowest CP content (96g kg-1 DM) (P=0.001). The NDF and ADF content were lower (P<0.001) for beans and CV compared with the rest of the forage silages. Ryegrass silage had higher values of dry matter degradation, organic matter degradation, relative GP and SCFA (P<0.001). The highest values of digestible energy were for CV and bean silages (P<0.001). Ryegrass and CV silages showed higher levels in GP parameters, which could be associated with their better chemical composition characteristics, mainly protein and fiber content.

A DM sample of 800 mg was placed in a 125 mL flask with 90 mL of incubation solution (Menke & Steingass, 1988).…”

Because nitrogen (N) is a limiting nutrient in lowquality forages, supplementation with N sources has been used to supply ammonia to meet the requirements of rumen microbial population. The use of manure from livestock is an alternative method of supplying N in the feed of ruminants (Ortiz et al., 2007); however, they usually have low energy content for optimal rumen bacteria growth. An increase in cellulolytic activity of microorganisms in the rumen can increase the digestible energy due to better utilization of f ibrous feeds, and otherwise improving the supply of microbial protein. Bakery by-products and sugar industry are an attractive source of energy for ruminants.The method of silage preservation is based on converting the soluble carbohydrates in organic acids, mainly lactic acid under anaerobic conditions by lactic acid bacteria. The technique of in vitro gas production (Menke & Steingass, 1988), or the modif ications by Theodorou et al. (1994) simulating the digestive processes generated from microbial production, allows us to know the fermentation and degradation of food according to the nutritional quality and availability of nutrients for ruminal bacterial. The aim of this study was to evaluate the effect of swine manure (SM), poultry waste (PW) and urea (U) as nitrogen sources and of molasses (M) or bakery by-product (BB) as a carbohydrate sources, with and without the addition of a bacterial additive, on chemical composition and in vitro gas production of silages based on corn stover (CS). Short communicaton. Effects of adding different AbstractThe use of protein-rich by-products based in swine manure (SM), poultry waste (PW) or chemicals compounds as urea (U), as well as energy products like molasses (M) and bakery by-product (BB), is a viable method to produce good quality silage. In addition, the use of a bacterial additive can improve the fermentation characteristics of silage. The objective of this study was to determine chemical composition, in vitro gas production (GP) and dry matter disappearance (DMd), using different sources of protein and energy in silage. The silages were made using SM, PW or U as protein sources and M or BB as energy source, with corn stover and with or without a bacterial additive. The organic matter (OM) content was higher (p < 0.001) in silages with UBB, UM and SMBB compared with the rest of the treatments; meanwhile crude protein content was higher (p < 0.001) in silages with U. The addition of a bacterial additive increased (p < 0.05) OM content and decreased (p < 0.05) fiber content. Total GP was higher (p < 0.05) in silages containing BB, but DMd was higher (p < 0.05) in silages with U and SMBB. The inclusion of a bacterial additive decreased (p < 0.05) GP and DMd. The use of alternative sources of protein such as poultry and swine manure or urea, and of by-products of sugar industry and bakery is an alternative for silages based on corn stover. The results show that when properly formulated, the silages can provide more than 16% of crude protein and have DMd ...
