The chemical composition and digestibility of twelve plant samples (Arthrocnemum macrostachyum, Atriplex canescens, Artemesia herba-alba, Astragalus gombo, Calobota saharae Ceratonia siliqua, Gleditsia triacanthos, Hedysarum coronarium, Medicago sativa, Ononis natrix L, Hordeum vulgare and <...

the first purpose of this study is to present an alternative robust model in order to describe ruminal degradation kinetics of forages and to minimize the fitting problems. for this purpose, the korkmaz-uckardes (ku) model, which has a logarithmic structure, was developed. the second purpose of this study is to estimate, by using the korkmaz-uckardes (ku)model, the parameters tp (the time to pr...

degradation of dry matter (dm) and nitrogen (n) in fresh or frozen-thawed alfalfa and ryegrass was studied by using in situ technique. the forages were labeled with 15n during growth in a glasshouse, harvested at similar growth phase, and fresh (f) or frozen-thawed (ft) samples were incubated in the rumen of 3 sheep. there was no difference (p>0.05) between forage type (s) for the immediately s...

background: infertility is an increasing medical and social problem. in vitro fertilization (ivf) has become a common and accessible treatment for a wide variety of indications that have variable outcomes. natural killer (nk) cells have been identified as relevant immunological factors involved in reproductive success or failure. objective: the aim of this study was to compare the percentage of...

background: pyridaben, a pyridazinone derivative, is a new acaricide and insecticide for control of mites and some insects such as white flies, aphids and thrips. objective: this study was designed to elucidate how pyridaben can affect the sperms' morphological parameters, its dna integrity, and to estimate the effect of various quantities of pyridaben on in vitro fertilization rate. materials ...

elicitation with middle-viscous chitosan (30 mg/50 ml) significantly stimulated silymarin synthesis in silybum marianum hairy root cultures. the root cultures established by infection with agrobacterium rhizogenes ar15834 showed a potential for production of silymarin. elicitation with medium molecular weight of chitosan (0, 5, 10, 20, and 30 mg/50 ml) was used in order to improve silymarin pro...
