   This study investigated the effect of different levels of barley wet brewers on performance, rumen degradability, some blood parameters and gas production in fattening Zell male lambs. In the first experiment, in order to investigate different levels of barley wet brewers on performance and some blood parameters, in a completely randomized design with 4 experimental diets containing 0, 10, 2...

Alfalfa, red clover, orchardgrass and timothy were harvested in the vegetative stage, wilted and stored as hay, or ensiled in small batch silos (20 kg) at 60, 40 or 20% (direct cut) dry matter and were analyzed for compositional differences. A ruminally cannulated lactating cow, consuming 50% of her dry matter intake from hay crop silage, was used to measure in situ dry matter, N, neutral deter...

this experiment was designed to evaluate the effect of phenolic components of scrophularia striata powder on feed intake, digestion and fermentation, rumination kinetic and rumen ecosystem in lori-bakhtiari sheep. in this experiment, 12 six months old lambs and average weight 30±1.5 kg were fed with 0 (control), 3 and 6 percent scrophularia striata for one month. feed intake, digestibility, rum...

To determine the best ratios of alfalfa hay to corn silage with similar dietary NDF, cation-anion balance, energy and protein content in the lactating dairy cows, eight mid-lactating Holstein dairy cows with average body weight of 570 kg, and milk yield of 22 kg/d with 3.5% fat, were assigned to each of four experimental diets with alfalfa hay to corn silage ratios of 100:0, 67:33, 33:67 and 0:...

In a completely randomized design with a factorial arrangement (3× 5× 3), three fistulated sheep with an average body weight of 47.5 ± 2.5 kg were used to determine the effect of cutting and growing stages (no bloom , early bloom and full bloom) on chemical composition and In situ degradability of alfalfa (Medicago sativa). Nylon bags (50 µm pore size) were filled with 3.5 g of each sample and ...

OBJECTIVE This study aims to identify the relationship between odd- and branched-chain fatty acids (OBCFAs) and microbial nucleic acid bases in the rumen, and to establish a model to accurately predict microbial protein flow by using OBCFA. METHODS To develop the regression equations, data on the rumen contents of individual cows were obtained from 2 feeding experiments. In the first experime...

The objective of this study was to compare the effects of soybean (SB) meal (SBM) with increased rumen undegradable protein as roasted SB (RSB), extruded SB (ESB) or their equal blend (RSB + ESB) on production performance, nutrient digestibility, N-utilization efficiency, and blood metabolites in mid-lactation dairy cows. Eight lactating Holstein cows (BW = 534 ± 52 and DIM = 104 ± 5; mean ± SD...

The relative importance of duration of sward regrowth and rumen fill and fermentation on the control of grazing time and intake rate during the first grazing session of the day were studied. Four lactating dairy cows were allowed to graze ryegrass (Lolium perenne) swards, with five different regrowth periods after mowing (6, 9, 16, 22 and 30 d). The cows were allowed to graze until they stopped...

An extensive in vitro study was conducted to delineate the influence of levels and source of sulfur besides rumen fungi habitat on the degradation of pearl millet stover dry matter and fibrous constituents. The results revealed that degradability of dry matter, organic matter, acid detergent fibre, neutral detergent fibre and cellulose from pearl millet stover was maximized (P<0.05), irrespecti...

Abstract Background Brewers’ spent grain (BSG) typically contains 20% – 29% crude protein (CP) with high concentrations of glutamine, proline and hydrophobic non-polar amino acid, making it an ideal material for producing value-added products like bioactive peptides which have antioxidant properties. For this study, was extracted from BSG, hydrolyzed 1% alcalase flavourzyme, the generated hydro...
