Six mature sheep were fed restricted amounts of either a medium quality roughage or a 1 : 1 mixture of the roughage and barley grain. Disappearance of DM of three roughages (barley straw, oat hay and lucerne hay) from synthetic ®bre bags incubated in the rumen for 6 and 24 h was determined. Also, during intraruminal infusions of NH4C1, synthetic ®bre bags containing each of the three roughages ...

In this experiment the effects of lead and lead-free petrol applied at the following doses of: 0, 2, 4 and 6 cm • kg' of soil on growth and development of triticale and biochemical properties of the soil were studied. For detoxication of petrol organic amendment with barley straw was applied. The experiment was performed in two experimental series with and without triticale cover. It was found ...

4 ruminally cannulated cows were fed a forage diet (93% hay + 7% straw) and a mixed diet (33 % hay + 7% straw + 40% barley) in a 2 x 2 crossover experimental design. In sacco degradation of forage, fibrolytic activities (polysaccharidases and glycosidases) of the solid-associated bacteria (SAB), and distribution of the 3 main cellulolytic bacterial species (Fibrobacter succinogenes, Ruminococcu...

The phytase purple acid phosphatase (HvPAPhy_a) expressed during barley seed development was evaluated as transgene for overexpression in barley. The phytase was expressed constitutively driven by the cauliflower mosaic virus 35S-promoter, and the phytase activity was measured in the mature grains, the green leaves and in the dry mature vegetative plant parts left after harvest of the grains. T...

This study was conducted to evaluate the effect of feeding treated wheat straw with urea and whey on fattening lambs performance. About 4.5 kg urea and 1.5 kg salt were dissolved in 40 L water and mixed with 30 L of whey. The solution was spread over 100 kg chopped wheat straw. Thirty two male lambs were randomly divided into four feeding groups to compare performance with diets based on barley...

Barley straw serves as livestock feed and mulch for soil water conservation in the mixed barley-livestock systems of Ethiopian highlands. High demand barley biomass system creates competition between two uses. This study aimed to identify determinants utilization feed. Data on production use were collected from 236 households using a structured questionnaire. Use purposes at three levels, 0–15%...

1. Alkali (sodium hydroxide)-treated wheat straw was given to six rumen- and abomasal-cannulated sheep to study the rumen degradation of cotton-seed meal (CSM) and barley (B), and the effects of these supplements on nitrogen retention and efficiency of bacterial protein synthesis were measured. 2. N degradation, using porous synthetic (nylon) bags incubated within the rumen (P), and in vivo mea...

improvement of soil properties through sustainable agriculture requires suitable management of plant residues. this study was conducted to investigate the effect of different types and managements of plant residue on soil physical properties in a field experiment as factorial based on rcbd with three replicates. the first factor was residue type including barley straw and alfalfa residue, and t...

Our objective was to evaluate the effects of substituting feather meal (FM) for soybean meal (SBM) on ruminal fiber fermentation, lamb gain, blood metabolite profiles, and wool growth. A SBM supplement was formulated, and FM replaced either 33% (33FM), 66% (66FM), or 100% (FMS) of the SBM protein. Four ruminally cannulated wethers were used in a 4 x 4 Latin square design to study in situ rumina...
