Feeding value of ensiling fresh cattle manure with molasses or bakery by-products in lambs

Nutritive value of ensiled pig excreta, poultry litter or urea with molasses or bakery by-products in diets for lambs

“…Maize stover, the above-ground residue of maize plants grown for grain, is used intensively for ruminant feeding. It has a low crude protein content (<40 g/kg DM), but our findings (Bórquez et al, 2009;2010) showed that ensiling this by-product with fresh cattle manure and bakery by-products (BBP) or sugarcane molasses (MOL) produced silages with acceptable quality. Their dietary inclusion (250 g/kg dry matter) in total mixed rations offers an alternative feed to finishing lambs.…”

“…Al-Rokayana et al (1998) studied silage made with sorghum straw, PL and MOL, including different levels in diets, in lambs, and found that digestibility of DM, OM and CP was higher than the control (without silage). This suggests that the soluble carbohydrates in MOL that were available to the bacteria were an adequate source of energy (Bórquez et al, 2009). Because both in vitro and in sacco assays indicated that diets with poultry litter silages had higher degradation than others, the higher feed intake in lambs fed diets with PL plus MOL silages could explain the absence of differences in total tract digestion of diets.…”

Ensiling a dry bakery by-product: effect of hydration using acid whey or water associated or not at urea

“…Although we did not evaluate the presence of these compounds on bakery by-product prior to ensiling, the concentration of oxalic and phytic acids should most likely be higher than that found in the silages because the ensiling process (fermentation) negatively affects these acids, as reported in tropical forage legumes (MARTENS et al, 2014). Although there are not studies about bakery by-product silages, the use of bakery by-products had been used as additive to improve the fermentation of cattle manure silages (BÓRQUEZ et al, 2009). In contrast to the obvious benefits of acid whey hydration, the application of urea did not increase the production of organic acids; otherwise, the acetic and propionic acids decreased when a high urea rate was used at ensiling (except for the silages hydrated with acid whey at 250 mL kg -1 ).…”

Nitrogen losses in ruminant manure management and use of cattle manure vermicast to improve forage quality

“…For decades efforts have been put to produce ingredients for animal feedstuff from manure (Woesttyne and Verstrate 1995). To utilise cattle manure as feedstuff different processing methods (dehydration, compost silage, single cell protein production, pelleting, deep stacking, chemical preservation, and chemical enhancement of digestibility) have been employed (Bórquez et al 2009;Sarwar et al 2011). Usage of cattle manure as feedstuff in ruminant has the advantage of reducing pollution due to animal waste in addition to reducing feeding cost (Martí-nez-Avalos et al 1998).…”

“…Usage of cattle manure as feedstuff in ruminant has the advantage of reducing pollution due to animal waste in addition to reducing feeding cost (Martí-nez-Avalos et al 1998). However, some factors have affected efficient utilisation of cattle manure and these includes palatability, ease of handling, product quality and consumer acceptance (Bórquez et al 2009). The method commonly used in treating cattle manure as feed resource is fermentation with soluble Nitrogen source such as urea and carbohydrate such as cane molasses through silage (Martínez-Avalos et al 1998;Sarwar et al 2006).…”
