Chemical composition and nutritive values of by-product feedstuffs (BPF) used for small ruminants were evaluated. Four BPF from groundnut shells (GNS), maize cobs (MC), cassava peels (CaP), and citrus pulp/peels waste (CPPW) were used to prepare complete diets fed to goats and sheep in separate trials. Twelve goats and 16 sheep 16±18 months old weighing on average 12.96 0.28 and 14.05 0.18 kg, ...

effect of electron beam irradiation on degradability coefficients and ruminal- postruminal digestibility of dry matter and crude protein of soybean meal, canola meal and lathyrus sativus seed, irradiated at doses of 50, 100 and 150 kgy was investigated. ruminal degradability of dry matter and crude protein was determined by in situ method using two cannulated holstein heifers. ruminal- postrumi...

In the present study, in vitro digestibility and structure of soybean protein isolates (SPIs) prepared from five soybean varieties were investigated in simulated gastric fluid (SGF), using FT-IR microspectroscopy and SDS-PAGE. The result indicated that β-conformations were prone to be hydrolyzed by pepsin preferentially and transformed to unordered structure during in vitro digestion, followed ...

for treatment of anti-nutritional factors(anfs), (?-n-oxalyl -l- ?, ? -diaminopropionic acid (?-odap) and condensed tannin (ct)) in grass pea, some such alkali treatments as naoh, nahco3, kmno4 and wood ash, besides water soaking and polyethylene glycol (peg) (6000 mw) were employed . metabolizable energy (me) of treated and of untreated grass pea was assessed using gas production technique, tw...

It is known that extraction of some grasses with neutral detergent (ND) increases the in vitro digestibility [Kennedy, P.M., Lowry, J.B., Conlan, L.L., 1999. J. Sci. Food Agric. 79, 544]. Here, we report experiments which de®ned the contribution of ND components to digestibility increases. Substrates were prepared from spear grass (Heteropogon contortus) by boiling at neutral pH in solutions of...

The nutritive value of meat and bone meals (MBM) was assessed for broilers. The MBM was produced according to the revised (pressure) processing system ordered by the European Union (EC 96/449). Three batches of MBM from cattle (MBMcattle) and three from pigs (MBMpig) with different ash contents (224, 306, 387, and 209,293, 430 g/kg, respectively) were tested for digestibility at a 10% inclusion...

Grape stems are a by-product of wine production which is managed as waste. Animal feeding arises potential alternative. However, its practical use may be compromised by high lignin content. In this sense, hydrolysis emerges strategy to increase fibre digestibility. addition, due and variable moisture content, it should dried prevent microbial deterioration washing pre-treatment reduce sugar con...

The effect of grape pomace (Vitis vinifera) and in oak leaf (Quercus libani) tannins by three runs of in vitro gas production on the organic matter digestibility (OMD) and in situ dry matter (DM) and crude protein (CP) disappearance were studied in four sheeps. Polyethylene glycol (PEG) was used to deactivate the tannins. In vitro gas production was recorded at 2, 4, 6, 8, 12, 48, 72, 96 and 12...
