ABSTRACT The trial was conducted with the objective to evaluate fresh sugarcane as a replacement for corn silage on dry matter intake, ruminal parameters (pH, short chain fatty acids, and ammonia nitrogen concentration), degradation kinetics of forages concentrate in maintenance adult goats. Four nonlactating ruminally cannulated goats were used 4 × Latin square design 0, 33, 67, 100% by indepe...

the effect of feeding of soaked barley straw on milk production and composition and rumen characteristics was studied. the degradability of soaked barley straw (for 24, 48 and 72 hours) and unsoaked barley straws were studied in the first experiment. the unsoaked barley straw had more readily degraded fraction (a) than soaked straw treatments (p> 0.05). there was no significant difference betwe...

The extrusion of leguminous seeds induces the formation Maillard reaction compounds (MRC) as a product protein advanced glycation and oxidation, which lowers degradability in rumen. However, quantitative relationship between parameters pretreatment (i.e., addition reducing sugars) extrusion, MRC has not been established yet. Moreover, fate main stable MRC, Nε-carboxymethyl-lysine (CML), excreto...

The in vivo digestibility, the rates of fermentation and passage and the rumen fermentation pattern were compared in ̃ Granadina goats and Segurena wethers fed alfalfa hay (AH), alfalfa hay/sugar beet pulp, 4:1 (AH/SB) and alfalfa hay/sugar beet pulp /oat grain, 3:1:1 (AH/SB/OG) at approximately maintenance level. The animals were at stall and no selectivity was practised. The nylon bag techniqu...

This study was conducted to determine in vitro crude protein degradation (IVDP) parameters and effective crude protein degradability (EPD) of various feeds using the modified in vitro gas production (GP) technique. Feed samples were alfalfa hay, soybean meal, soybean, rapeseed meal, sunflower meal and fish meal. Rumen fluid was collected before the morning feeding from four rumen fistulated lam...

In a previous study origanum oil (ORO), garlic oil (GAO), and peppermint oil (PEO) were shown to effectively lower methane production, decrease abundance of methanogens, and change abundances of several bacterial populations important to feed digestion in vitro. In this study, the impact of these essential oils (EOs, at 0.50 g/L) on the rumen bacterial community composition and population was f...

This research was carried out to evaluate the effects of flavone, myricetin, naringin, catechin, rutin, quercetin, and kaempferol at the concentration of 4.5% of the substrate (dry matter basis) on the rumen microbial activity in vitro. Mixture of guinea grass and concentrate (60 : 40) was used as the substrate. The results showed that all the flavonoids except naringin and quercetin significan...

Twelve dietary combinations were prepared using 70 parts of fermented wheat straw (FWS) as the sole roughage supplemented with 30 parts of either the low protein concentrate mixture (Conc.-I), high protein concentrate mixture (conc.-II), maize grains (M), solvent extracted mustard cake (DMC), deoiled rice bran (DRB), uromol bran mixture (UBM), deep stacked poultry litter (DSPL), dried poultry d...

It is important to assess the nutritional concentrations of forage before it can be used for tremendous improvements in dairy industry. This improvement requires a rapid, accurate, and portable method detecting nutrient values, instead traditional laboratory analysis. Fourier-transform infrared (ATR-FTIR) spectroscopy technology was applied, partial least squares regression (PLSR) backpropagati...

A method was developed for extracting enzymes from micro-organisms closely associated with ammonia-treated straw (NH3-S) that had been incubated in nylon bags in the rumen. Incubation of washed straw with 125 ml carbon tetrachloride/l and 20 micrograms lysozyme/ml for 3 h at 37 degrees gave carboxymethylcellulase (EC 3.2.1.4; CMCase) and NAD-linked glutamate dehydrogenase (EC 1.4.1.2; GDH) acti...
