Honey bee colony winter loss rates for 35 countries participating in the COLOSS survey for winter 2018–2019, and the effects of a new queen on the risk of colony winter loss
(Taylor and Francis Ltd., 2020)
This article presents managed honey bee colony loss rates over winter 2018/19 resulting from using the standardised COLOSS questionnaire in 35 countries (31 in Europe). In total, 28,629 beekeepers supplying valid loss data ...
The effect of diet types on some quality characteristics of artificially reared Apis mellifera queens
(Taylor & Francis Ltd, Abingdon, 2020)
The influence of various diets on the quality of Apis mellifera queens was assessed. Colonies intended for queen cell production were assigned to four groups fed on (1) sugar-only, (2) mix of sugar, honey and fresh pollen, ...
Structural characteristics of circulating immune complexes in calves with bronchopneumonia: Impact on the quiescent leukocytes
(Elsevier, 2020)
Calf bronchopneumonia is accompanied by increased level of circulating immune complexes (CIC), and we analysed size, and protein and lipid constituents of these CIC with an attempt to elucidate the connection between the ...
Parathyroid hormone response in treatment of subclinical hypocalcemia inpostpartum dairy cows
(Elsevier, 2020)
The aim of this study was to evaluate different treatments of postpartum subclinical hypocalcemia in dairy cows with emphasis on PTH response. Twenty four cows with subclinical hypocalcemia (Ca 1.4–2.0 mmol/L), out of 180 ...
Tresholds of blood variables obtained by receiver operating characteristic analysis for indication of fat and glycogen content in the liver of postpartum dairy cows
(Taylor & Francis Ltd, Abingdon, 2020)
The objective was to determine optimal thresholds of blood variables that are associated with liver lipid and glycogen content in dairy cows. Liver specimens of 15 Holstein dairy cows were taken 2 weeks postpartum (PP) and ...
Recovery of brain cholinesterases and effect on parameters of oxidative stres and apoptosis in quails (Coturnix japonica) after chlorpyrifos and vitamin B1 administration
(Elsevier, 2021)
Chlorpyrifos is a extensively used organophosphate pesticide (OP). In this study, we closely looked into neurotoxicity of CPF and effect of vitamin B1, by checking the levels of cholinesterases, determining the activity ...
Oxidative Stress, Endoparasite Prevalence and Social Immunity in Bee Colonies Kept Traditionally vs. Those Kept for Commercial Purposes
(MDPI, 2020)
Commercially and traditionally managed bees were compared for oxidative stress (superoxide dismutase (SOD), catalase (CAT), glutathione S-transferase (GST) and malondialdehyde (MDA)), the prevalence of parasites (<i>Lotmaria ...
Estimation of honey bee colony infection with Nosema ceranae and Varroa destructor using fluorescence spectroscopy in combination with differential scanning calorimetry of honey samples
(Taylor and Francis, 2021)
In this preliminary study, we applied the Multivariate Curve Resolution- Alternating Least Squares (MCR-ALS) method to analyze the excitation-emission matrices of multifloral honey samples, combined with differential ...
Causes of admission, length of stay and outcomes for common kestrels in rehabilitation centres in the Czech Republic
(Nature Research, 2021)
Rehabilitation centres help injured animals to recover and return back to the wild. This study aimed to analyse trends in intake and outcomes for the common kestrels (Falco tinnunculus) admitted into rehabilitation centres ...
Potential of Fumagillin and Agaricus blazei Mushroom Extract to Reduce Nosema ceranae in Honey Bees
(MDPI, 2021)
Depending on the infection level and colony strength, Nosema ceranae, a microsporidian endoparasite of the honey bee may have significant consequences on the health, reproduction and productivity of bee colonies. Despite ...
