the effects of a multi enzyme were evaluated on performance and nutrient digestibility in african domesticated ostrich at 14 months ages. there were three treatments as; common diet (1), common diet plus multi enzyme (0.350 gkg -1) (2) and common diet plus multi enzyme (0.700 gkg -1) (3). 18 ostrich were used in this experiment (6 birds per treatment). there was significant effect of enzyme sup...

In the bacterial processes involved in the mitigation of nitrogen pollution, an adequately high carbon-to-nitrogen (C : N) ratio is key to sustain denitrification. We evaluated three natural materials (woodchips, barley grains, and peanut shells) as carbon sources for low C : N wastewater. The amount of organic matter released from these materials to aqueous media was evaluated, as well as thei...

This experiment was conducted to determine the possibility of replacing part of the barley grain by hydroponic barley fodder (HBF), and evaluating its effect on digestibility, rumen parameters, microbial protein synthesis and blood parameters in sheep. Four male Kermani sheep, 18-month-old (34.7 ± 1 kg live weight) were randomly assigned to a change over 4 × 4 design and fed the experimental di...

Eight ruminally fistulated steers (352 +/- 27 kg BW) were used in a replicated 4 x 4 Latin square design. Treatments were 1) 70% rolled barley +30% timothy hay (HC), 2) HC+folic acid (2 mg/kg BW; HC+F), 3) 30% rolled barley + 70% timothy hay (HF), and 4) HF+F. Total tract apparent digestibility of DM and CP were greater (P < or = .05) in steers fed the HC diet, whereas that of ADF and NDF was g...

Effects of several organic acids on ion uptake and retention and on respiration in barley roots having low and high KCl contents were assayed by measurements of K(+), Na(+), Ca(2+), Cl(-), and oxygen uptake. Organic acids with high pK(a) values increase the permeability of roots to ions and decrease respiration when present in sufficient concentrations at pH 5 but have no inhibitory effects at ...

Nucleotide sequence of the barley chloroplast psbC gene We present here the eequenoe of psbC gene from barley ohloroplaBt genome, ooding for the 43 kDa photoBjrBtem II protein (see alBO CarlBberg ReB.Commun., 49:647 for the last 500 b.p.). The 5'-end of psbC overlaps with the 3'-end of previously sequenoed psbD gene (Nuo Acids Res. 16:5686). The deduced amino acid Bequenoe is presented.

An analysis of the lipids in isolated barley (Hordeum vulgare L.) aleurone layers after 12 hours incubation in the presence or absence of gibberellic acid showed no quantitative or qualitative changes. Longer incubation periods resulted in some lipid degradation which was greater in the presence of 1 mum gibberellic acid.Glycerolipid synthesis was measured in isolated barley aleurone layers dur...
