Context Tagasaste (Cytisus proliferus), a fast-growing leguminous tree, has potential to supplement pasture production in steep-hill country and increase resilience.Aims In the companion paper, we quantified tagasaste characteristics. Here, determine effect of proximity 10-year-old trees on productivity eight species including grasses (perennial ryegrass, Lolium perenne; cocksfoot, Dactylis glo...

1. We demonstrate the potential of extracting high-resolution dietary information from stable carbon isotopes ( δ 13 C) in horse tail-hair, in response to short-term changes in diet in controlled feeding experiments. 2. Tail hairs were sampled from six horses that had been equilibrated to C3 forage and were then subjected to a series of short-term diet switches to the C4 Coastal Bermuda Grass (...

Herbal medicine is an ancient practice that has been gaining acceptance of the medical class through scientific studies that prove its effectiveness. However, its use should still be cautious. Medicinal plants have potential toxic effects not yet discovered, and may have unproven interactions with other medications. The use of drugs during pregnancy is still very dangerous and vigorously studie...

The effects of 5 factors (template DNA, Mg(2+), dNTPs, Taq DNA polymerase, and primer) on the polymerase chain reaction (PCR) were investigated to optimize the start codon targeted polymor-phism (SCoT)-PCR system of Dactylis glomerata L., using an orthogo-nal design L16 (4(5)). A suitable SCoT-PCR system for D. glomerata was established; the 20 μL reaction volume contained 3.0 mM Mg(2+), 0.2 mM...

Isothiocyanates and substituted pyrazoles were combined to form a series of novel isothiocyanates with highly effective herbicidal activity. The target compounds were analyzed by elemental analysis, 1H-NMR, EI-MS and IR spectroscopy. The synthesized compounds, particularly compounds 3-1 and 3-7, exhibited good herbicidal activities against four weeds. The EC(50) values of compound 3-1 against E...

Preference value means livestock preference to eat some plants relative to other plants or species. Accordingly, by studying the preference values, the range managers could determine the rangelands grazing capacity to achieve the optimum performance of livestock and to guarantee the stability of rangeland ecosystem. The objective of this study was to determine the preference value of perennial ...

Abstract Background Antibiotics used to treat livestock species enter agricultural fields when they are excreted by grazing animals or present in manure that is added as fertiliser. In the European Union, potential effects of such antibiotics on terrestrial plants must be evaluated following standardised OECD 208 method, which specifies crop and wild should serve “sentinels” for assessing antib...

Low dietary energy and decreased intake of herbage have been attributed to the reduced performance grazing dairy cattle. We hypothesized that grasses with inherently greater would interact in a complementary way condensed tannins (CT) birdsfoot trefoil increase by heifers. Eight pasture treatments comprising high-sugar perennial ryegrass (Lolium perenne L.), orchardgrass (Dactylis glomerata mea...
