Evaluation of the Quality of Guinea Fowl () Eggs from Free-Range Farming Depending on the Storage Period and Age of Laying Hens.

The aim of the study was to determine the changes occurring in the eggs of helmeted guinea fowl () from free-range farming in relation to the laying season and storage time. The experimental material consisted of 360 guinea fowl eggs, collected in the first, second and third laying seasons and stored for 7, 14 and 21 days. After each period, physical and physicochemical characteristics of the eggs were determined, as well as the basic chemical composition and mineral content of the albumen and yolk and the yolk fatty acid profile.

Interaction between Enrofloxacin and Three Essential Oils (Cinnamon Bark, Clove Bud and Lavender Flower)-A Study on Multidrug-Resistant Strains Isolated from 1-Day-Old Broiler Chickens.

Avian pathogenic Escherichia coli (APEC) causes a variety of infections outside the intestine. The treatment of these infections is becoming increasingly difficult due to the emergence of multi-drug resistant (MDR) strains, which can also be a direct or indirect threat to humans as consumers of poultry products. Therefore, alternative antimicrobial agents are being sought, which could be essential oils, either administered individually or in interaction with antibiotics.

Evaluation of the Antibacterial Activity of Gentamicin in Combination with Essential Oils Isolated from Different Cultivars and Morphological Parts of Lavender ( Mill.) against Selected Bacterial Strains.

The aim of the study was to investigate the antibacterial effects of essential oils isolated from different cultivars and morphological parts of lavender ( Mill.) in combination with the aminoglycoside antibiotic gentamicin. This in vitro study analyzed the effectiveness of the combinations of gentamicin and lavender essential oils against the following strains: ATCC 25923, MRSA and ATCC 9027.

Essential Oils as Effective Enhancers of Fluconazole Antifungal Activity against .

The increasing prevalence of resistance to commercial antifungal agents in recent decades has prompted modern medicine and veterinary medicine to search for combined treatment options. The aim of the study was to determine the activity of essential oils from different cultivars and morphological parts of the medicinal lavender () in combination with fluconazole against ATCC 10231 strain. The effect of the combination of lavender essential oil with fluconazole was tested using the checkerboard method, and the obtained results were interpreted on the basis of fractional inhibitory concentration indices (FICIs).

The effect of lavender (Lavandula angustifolia) essential oil as a drinking water supplement on the production performance, blood biochemical parameters, and ileal microflora in broiler chickens.

The aim of this study was to evaluate growth performance, selected biochemical blood parameters, and the microbiota of ileal digesta in broiler chickens provided with drinking water containing an addition of natural lavender essential oil (LEO). The experiment was carried out on a commercial farm using n = 300 unsexed Ross-308 broiler chickens. One-day-old chicks were randomly assigned to three groups of 100 chickens each (five replications, 20 individuals each).
