For one of Canada’s most important regions crop production—the prairies—it’s uncertain if cover crops can be successfully integrated into rotations; so, will soil nitrogen (N) cycling influenced to benefit main crops? To address these gaps, we compared a rotation with (CC) vs. without (LR) from 2018 2021 in Saskatoon, SK. The were grown sequence wheat–canola–potato–pea; the included red clover,...

AIM The objective of this study was to investigate the effect of different vegetable oils on rumen fermentation and concentrations of beneficial cis-9 trans-11 C18:2 conjugated linoleic acid (CLA) and trans-11 C18:1 fatty acid (FA) in the rumen fluid in an in vitro condition. MATERIALS AND METHODS Six vegetable oils including sunflower, soybean, sesame, rice bran, groundnut, and mustard oils ...

Twenty-four yearling Boer x Spanish goats were used in a crossover experiment to determine the effects of tethering on herbage selection, intake and digestibility, grazing behavior, and energy expenditure (EE) with high-quality herbage. Four 0.72-ha paddocks of wheat (Triticum aestivum) and berseem clover (Trifolium alexandrium) were grazed in the spring. Each paddock hosted 6 animals, 3 with f...

The reduced availability of water resources in Egypt has imposed the need to intensify use wastewater for crop irrigation alluvial soils. Relevant effects can derive from contents potentially toxic metals (PTMs) supply soils, crops, and groundwater these areas. For this reason PTM content be monitored evaluate minimize health hazards. Therefore, context, two areas SE Nile Delta subjected 25 yea...

AIM The aim was to determine the chemical composition and metabolisable energy (ME) content of feedstuffs used in ruminant animals using in vitro method. MATERIALS AND METHODS A total of 18 feedstuffs used for ruminant feeding including cultivated non-leguminous fodders like maize, sorghum, pearl millet, and oat; leguminous fodders like cowpea and berseem; agro-industrial by-products such as ...

Rhizobium tropici CIAT899 induced chlorosis in the leaves of its symbiotic hosts, common bean (Phaseolus vulgaris L.), siratro (Macroptilium atropurpureum Urb.), and Leucaena leucocephala (Lam.) de Wit. Chlorosis induction by strains CIAT899 and CT9005, an exopolysaccharide-deficient mutant of CIAT899, required carbon substrate. When the bacteria were added at planting in a solution of mannitol...

The present investigation included two experiments. The first dealt with mineral levels in hair and blood plasma as possible indicators for the different minerals status of growing and adult Friesian and buffaloes which were fed under practical conditions during the period from November 1988 to August 1989. Friesian and buffaloes were almost similar in age and body weight and were fed winter ra...
