BACKGROUND Gastrointestinal and respiratory diseases in calves and piglets lead to significant economic losses in livestock husbandry. A high morbidity has been reported for diarrhea (calves ≤ 35%; piglets ≤ 50%) and for respiratory diseases (calves ≤ 80%; piglets ≤ 40%). Despite a highly diverse etiology and pathophysiology of these diseases, treatment with antimicrobials is often the first-li...

To enhance the genetic resource base of Echinacea purpurea (L.) Moench, a tetraploid was developed by treating seeds with different concentrations of colchicine. For further multiplication, in vitro micropropagation through adventitious shoot induction and proliferation was achieved. Shoot buds were induced directly on adaxial surface of mature leaf tissues growing on MS medium supplemented wit...

this experiment was conducted to evaluate the efficacy of different levels of echinacea (echinacea purpurea) methanol extract on the growth performances (final weight (fw), daily growth ratio (dgr), feed conversion rate (fcr), voluntary feed intake (vfi) and protein efficiency ratio (per) and some of hematological parameters (hemoglobin (hb), hematocrit (hct), red blood cell (rbc) and white blo...

Due to the limited availability of effective pharmaceutical products and serious side effects of the available therapy for leishmaniasis, search for useful medicinal plants is necessary. Previous studies reported preventative effect of Echinacea against Leishmania infections through immunologic stimulation. Here we tested concentrated ethanolic extract of the root of Echinacea purpurea prepared...
