Ectoparasite fauna of domestic waterfowl in the northern region of the Republic of Moldova RUSU, Ștefan; ERHAN, Dumitru; ZAMORNEA, Maria; CHIHAI, Oleg; RUSU, Viorelia; GOLBAN, Rita; GOLOGAN, Ion; CIBOTARU, Elena A study on the ectoparasite fauna of domestic waterfowl (ducks and geese) from the Anatidae family in the northern region of the Republic of Moldova showed that domestic ducks (Anas platyrhynchos domesticus, Linnaeus, 1758) were infested with six species of chewing lice: Trinoton querquedulae, Anatoecus icterodes, Anatoecus dentatus, Anaticola crassicornis, Anaticola anserinum, and Menopon obscurum, as well as the gamasid mite Dermanyssus gallinae. Domestic geese (Anser anser domesticus, Linnaeus, 1758) were found to host ten species of ectoparasites, including eight species of chewing lice: Trinoton querquedulae, Trinoton anserinum, Anatoecus icterodes, Anaticola crassicornis, Anaticola anserinum, Anatoecus adustus, Menopon obscurum, and Lipeurus caponis. In addition, geese were infested with the gamasid mite Dermanyssus gallinae and the argasid tick Argas persicus.These findings indicate a high diversity of ectoparasites infesting domestic ducks and geese in the northern region of the Republic of Moldova, with differences between host species. The presence of lice, mites, and ticks highlights the need for monitoring and controlling ectoparasite populations in order to maintain the health of domestic waterfowl in this region.

The role of stimulative feeding of nurse bees in queen rearing technology

The role of stimulative feeding of nurse bees in queen rearing technology EREMIA, Nicolae; JEREGHI, Vitalie; CATARAGA, Ivan The aim of this study was to evaluate the role of stimulative feeding of nurse bees in the technological process of queen rearing. Under conditions of absent maintenance nectar flow, nurse colonies were fed 50% sugar syrup supplemented with the biostimulator Cloramicob. Supplemental feeding improved the physiological condition of the bees and stimulated royal jelly secretion for grafted larvae, which increased larval acceptance for rearing. It also promoted queen cell development, particularly length and diameter, and increased the body mass of both unmated and mated queens. The best overall response was generally obtained at the dose of 2.0 ml/L, while all stimulated groups outperformed the unstimulated control.

Innovative biological technology for the prevention and control of endoparasites in domestic waterfowl RUSU, Ștefan; ERHAN, Dumitru; ZAMORNEA, Maria; RUSU, Viorelia; GOLBAN, Rita; GOLOGAN, Ion; CIBOTARU, Elena; NAFORNIȚA, Nicolae This study investigates the diversity of endoparasites in domestic waterfowl (ducks and geese) of the family Anatidae, raised in anthropized environments in the Republic of Moldova, and evaluates the potential of a plant-based preparation for their control. Parasitological examinations revealed a diverse endoparasitic fauna, including class Trematoda (Echinostoma revolutum, E. robustum), class Secernentea (Amidostomum acutum, A. anseris, Ascaridia galli, Heterakis gallinarum, Ganguleterakis dispar), and class Conoidasida (Eimeria anseris, E. nocens, E. truncata). Given the prevalence of these parasites, a plant-derived product, Endopalmivet, based on extracts of Tanacetum vulgare, was tested. The product was administered in aqueous solutions of different concentrations, with the 20% solution showing the most promising results under the conditions of this study. Administration was carried out orally via drinking water, either as a single dose (prophylactic approach) or as two administrations at a 14-day interval (therapeutic approach). The results indicate a reduction in parasitic burden, varying depending on the parasite group and experimental conditions. Although the findings suggest promising potential, further rigorous studies are required to confirm efficacy, safety, and practical applicability.

Variations of the amino acid spectrum in the blood plasma of the rooster during the spermatogenesis cycle ROȘCA, Nicolae; BĂLAN, Ion; CIOCHINĂ, Valentina; BUZAN, Vladimir; BALACCI, Sergiu; ȚIȚEI, Victor; CREȚU, Roman; OSIPCIUC, Galina; TEMCIUC, Vlad; MEREUȚĂ, Ion The purpose of this study is to highlight the response to experimental interventions by investigating of variations in the amino acid content in the blood plasma of roosters under the influence of biologically active compounds. The latter were obtained from the composition of sea buckthorn and red onion through techniques and methods of analysis (extraction, spectrophotometry). Blood samples from three groups of roosters were analyzed: control, experimental I and experimental II after a 30-day period of ration supplementation with biologically active compounds. Were determined 26 amino acids and their conformational states and 2 amino acid derivatives on the AAA-339 analyzer. The analysis of amino acid content in the blood plasma of roosters during the spermatogenesis cycle reveals significant changes in the amino acid profile between control and experimental groups (p<0.05). Changes in concentrations of essential, non-essential and specific amino acids suggest that experimental interventions may influence amino acid metabolism. The results contribute to the understanding of some metabolic mechanisms involved in spermatogenesis of birds.
