Plant-based and immunostimulant-enhanced diets modulate oxidative stress, immune and haematological indices in rainbow trout (Oncorhynchus mykiss)
by on with Žádné komentáře

Abstract: The aim of this study was to investigate the effects of three commercial diets, standard, immunostimulant-supplemented (β-glucan, vitamins C and E) and plant-based, on the degree of oxidative stress in tissues of rainbow trout (Oncorhynchus mykiss). Selected immune and … Read More

Opět pokračujeme v rámci našich projektů Ministerstva zemědělství s odběry včel. V našich experimentálních včelstvech jsme po přezimování našli i námi značené včely z podzimu minulého roku. Letos pokračujeme se studiem vlivu parazitace a viróz na imunitní systém včel a … Read More

Changes in haemolymph parameters and insect ability to respond to immune challenge during overwintering

Changes in haemolymph parameters and insect ability to respond to immune challenge during overwintering
by on with Žádné komentáře

Abstract: Overwintering is a challenging period in the life of temperate insects. A limited energy budget characteristic of this period can result in reduced investment in immune system. Here, we investigated selected physiological and immunological parameters in laboratory-reared and field-collected … Read More

Winter honeybee (Apis mellifera) populations show greater potential to induce immune responses than summer populations after immune stimuli

Winter honeybee (Apis mellifera) populations show greater potential to induce immune responses than summer populations after immune stimuli
by on with Žádné komentáře

Abstract: In the temperate climates of central Europe and North America, two distinct honeybee (Apis mellifera) populations are found in colonies: short-living summer bees emerge in spring and survive until summer, whereas long-living winter bees emerge in late August and … Read More

Vigour-related traits and immunity in hybrids of evolutionary divergent cyprinoid species: advantages of hybrid heterosis?

Vigour-related traits and immunity in hybrids of evolutionary divergent cyprinoid species: advantages of hybrid heterosis?
by on with Žádné komentáře

Abstract Hybrid advantage, described as the superiority of hybrids in some traits over their parents and termed the “heterosis effect,” is widely documented in the case of reciprocal crosses of parental species (i.e., hybrids representing the F1 generation). In fish, … Read More
