“…Thymol, eugenol, and carvacrol have similar chemical structures and exert synergic antimicrobial effects ( Bassole and Juliani, 2012 ), but it is necessary to optimize their formulation ( Zhai et al., 2018 ). In conclusion, it must be pointed out that although there are several viable approaches for pathogen control on meat and eggs in the conventional poultry industry, the selection of acceptable antibacterials is much more limited for organic poultry producers ( Arsi et al., 2019 ). The findings of this study provide useful data regarding effective strategies for pathogen control at organic farms.…”

In this study, the presence of antibiotics ( ANB ) residues was evaluated in poultry meat purchased from German and Lithuanian markets. In addition, the antimicrobial activity of 13 lactic acid bacteria ( LAB ) strains, 2 essential oils ( EO ) ( Thymus vulgaris and Origanum vulgare L.), and their compositions were tested for the purpose of inhibiting antibiotic-resistant Salmonella spp. ANB residues were found in 3 out of the 20 analyzed poultry meat samples: sample no. 8 contained enrofloxacin (0.46 μg/kg), sample no. 14 contained both enrofloxacin and doxycycline (0.05 and 16.8 μg/kg, respectively), and sample no. 18 contained enrofloxacin (2.06 μg/kg). The maximum residue limits ( MRLs ) for the sum of enrofloxacin and ciprofloxacin and for doxycycline in the poultry muscle are 100 μg/kg. Finally, none of the tested poultry meat samples exceeded the suggested MRLs; however, the issue of ANB residues still requires monitoring of the poultry industry in Germany, Poland, and Lithuania, despite the currently established low ANB concentrations. These findings can be explained by the increased use of alternatives to ANB in the poultry industry. Our results showed that an effective alternative to ANB, which can help to reduce the occurrence of antibiotic-resistant salmonella, is a composition containing 1.0% of thyme EO and the following LAB strains: Lactobacillus plantrum LUHS122, Enteroccocus pseudoavium LUHS242, Lactobacillus casei LUHS210, Lactobacillus paracasei LUHS244, Lactobacillus plantarum LUHS135, Lactobacillus coryniformins LUHS71, and Lactobacillus uvarum LUHS245, which can be recommended for poultry industry as components of feed or for the treatment of surfaces, to control the contamination with Salmonella strains. However, it should be mentioned that most of the tested LAB strains were inhibited by thyme EO at the concentrations of 0.5 and 1.0%, except for LUHS122, LUHS210, and LUHS245. Finally, it can be noted that the agents responsible for the inhibitory effect on Salmonella are not the viable LAB strains but rather their metabolites, and further studies are needed to identify which metabolites are the most important.

“…The requirements of the official regulations regarding the certification of organic products restrict the use of synthetic molecules in the organic chicken-rearing system, therefore natural herbal products could be a viable solution for disease control [29,30]. Therefore, the present study aimed to assess the anticoccidial efficacy of A. annua in farmreared broiler chickens.…”

(1) Background: Various studies on artemisinin and its derivatives have shown that Artemisia annua may be of therapeutic interest for different diseases, including chicken coccidiosis. This study aimed to evaluate the effects of Artemisia annua on farm-reared broiler chickens by analyzing both the anticoccidial efficacy and its effect on the intestinal microbiota of poultry. (2) Methods: The experiment was performed within three houses on a broiler chicken farm located in Romania. House 1 was the experimental group and received a diet with an addition of A. annua. Houses 2 and 4 were the control groups and received anticoccidials. The prophylactic efficacy of A. annua against coccidiosis was evaluated by recording the weight gain, feed conversion rate, number of oocysts per gram of feces, lesion score, and mortality rate. (3) Results: The chickens fed with A. annua showed a decreasing trend in the number of oocysts per gram of faeces, and their lesion score was 80% lower than in the control group. The weight gains of the chickens treated with A. annua was lower, whilst the feed conversion rate was better than in controls. (4) Conclusions: Artemisia annua showed promising results in the prophylaxis of coccidiosis. Overall, the broiler chickens that received A. annua presented promising zootechnical performances and medical data related to coccidiosis and gut microbiota.

“…According to the results of a global study conducted in 2016, which included an analysis of 128 world journals, out of 579 advertisements published in these journals, 178 or 31% of them referred to organic food products (Gebhardt & Heinz, 2018). Data show that world demand for organic food products grows at an annual rate of 20%, while it is estimated that the retail sales of such products annually exceed $ 100 billion (US$), with the trend that 93% of global consumers expect placement of exclusively those products that are produced according to the highest ecological standards (Arsi, Donoghue, Venkitanarayanan, & Donoghue, 2019;Hjelmar, 2011). In line with this trend in the global market, consumers' expectations are growing (Popesku, 2018) as well, and therefore they consider organic food products to be better in taste, more natural, healthier and safer than conventional alternatives STRATEGIC MANAGEMENT, Vol.…”

The aim of this paper is to define suggestions and guidelines for improving the placement of food products of organic origin in the AP Vojvodina market. The main task is to identify and analyse indicators that the final consumers consider most important when purchasing food products of organic origin. The data was collected by field and electronic studies on a sample of 500 final consumers about their expectations, attitudes and habits in the purchase and consumption of organic food. Descriptive statistics was used for data processing, while multiple regression analysis was used to interpret results and test the established hypotheses. The results showed the existence of statistically significant correlations between different indicators, such as: quality label, origin of the product, composition of raw materials, freshness, price, taste, place of sale and packaging and consumers' decision to purchase an organic food product. The results of the research will serve as a basis for the creation of a regression model for the successful placement of food products of organic origin in the AP Vojvodina market. The practical significance of the research is reflected in the fact that it will indicate to the supply chain managers the indicators that need to be optimized to ensure more efficient placement of organic products on the national market. Suggestions and recommendations for future research are provided in the paper.
