“…It is a fact that the poultry industry. In fact, there are many pathogens that high mortalities of birds and cause huge economic losses [49,50], and the widespread use of antibiotics has led to the emergence of antibiotic-resistant strains [51], so the world has recently turned to applying strict hygienic measures side by side with usage of save antibiotic alternatives to overcome MDR problem via the usage of natural safe products such as prebiotics, probiotics, symbiotic, postbiotics, hyperimmune serum [52,53], herbal extracts, organic acids, essential oils, nano-preparations and other safe products to improve avian gut microbiome to compete pathogens [54], and finally enhance birds' productivity.…”

scherichia coli (E. coli) is a widespread avian pathogen and usually is considered as a secondary pathogen for different infectious agents causing huge financial losses in the poultry industry. Thus, the current works aim to molecular detection of resistance and pathogenicity genes of E. coli isolated from broiler chicken farms. A total of 18 flocks out of 30 broiler flocks (60%) were positive for E. coli infection. On the base of the Congo red (CR) binding assay, 15 flocks out of 18 were identified as pathogenic E. coli (83.3%) and 3 flocks appeared as nonpathogenic E. coli (16.6%). All pathogenic E. coli were subjected to in vitro antibiotic sensitivity testing to select the most resistant isolates. Ten pathogenic E. coli isolates representing ten different broiler flocks were subjected for molecular identification via polymerase chain reaction (PCR) for both resistance and virulence genes. The most predominant isolated serotypes were O91, O128, O78, O124, O 2 and O44. These strains were related to EHEC, EPEC, ETEC, and EIEC. These E. coli isolates are multidrug resistant (MDR) to extensively drug-resistant (XDR). The virulence genes tsh, papC, iss, iutA, and hlyF were detected in 50% of isolates having 5 genes and 50% having 4 genes. All the tested isolates showed MDR genes 60% of isolates were positive for 5 resistance genes and 20% were positive for 4 resistance genes and 20% were positive for resistance 3 genes. We can conclude that E. coli continues to threaten poultry industry and further studies are recommended to found safe antibiotic natural alternatives to overcome E. coli MDR existing strains side by side with strengthening the bird's immunity and application of strict hygienic measures.

“…Several studies have demonstrated the potential benefits of using synbiotics instead of antibiotics in commercial broiler chickens ( Mohammed et al, 2022 ; Salem et al, 2023 ). Prebiotics, consisting of non-digestible oligosaccharides, can regulate or alter microbes’ makeup and/or function, helping preserve a healthy microbiota that inhibits the growth of pathogens via various regulatory mechanisms ( Ballini et al, 2023 ).…”

“…The use of safe alternatives to antibiotics, in particular probiotics, in the feed of broiler chickens improves the con-dition of the intestines of the bird and increases productivity, improves the quality of meat due to the optimal amount of amino acids and fatty acids in the meat of broiler chickens (Salem et al, 2023). In the world, the demand for protein of animal origin in the human diet is increasing, and the meat of broiler chickens, namely high-quality, inexpensive protein, is an essential source of it during production.…”

Probiotics are widely used for intensive technologies of growing broiler chickens due to their ecologically harmless properties, increasing productivity and obtaining safe and high-quality meat products. The purpose of the study was to determine the effect of the probiotic biopreparation Subtiform on the amino and fatty acid composition and biological value of chicken meat after drinking the probiotic biopreparation Subtiform in different doses. Broiler chickens from 28 to 42 days of age were given the probiotic bio preparation Subtiform, which contains Bacillus subtilis and Bacillus licheniformis at 2.5 × 109 CFU/g and dry milk serum per 20 birds in a cage: control - birds were not given probiotics with water; experiment 1 – 0.5 g/10 dm3 of water; experiment 2 – 2.0 g/10 dm3 of water; experiment 3 – 4.0 g/10 dm3 of water. The total content of amino acids in the breast meat of broiler chickens slightly increased in experiment 1 – by 1.71 % (Р < 0.01), in experiment 2 – by 3.57 % (Р ≤ 0.001), in experiment 3 – by 12.35 % (Р ≤ 0.001). The content of essential amino acids in breast meat was increased – 5.39 ± 0.04 mg/100 mg (Р ≤ 0.001) due to an increase in the content of methionine – 1.7 times (Р ≤ 0.01), leucine – by 1.3 times (Р ≤ 0.001), lysine and isoleucine – 1.2 times compared to the control group; the content of substituted amino acids also increased – 9.07 ± 0.04 mg/100 mg (Р ≤ 0.001) due to an increase in the content of aspartic acid – 1.2 times (Р ≤ 0.01), glutamic acid – 1.13 times (Р ≤ 0.01), as well as a decrease in glycine content – by 1.2 times (Р≤0.01) compared to the control group. The protein-quality index in experiment 3 was higher due to the increased content of tryptophan – 0.37 ± 0.025 mg/100 mg of meat (Р ≤ 0.001) and oxyproline – 0.06 ± 0.002 mg/100 mg of meat (Р ≤ 0.001). A positive effect of the probiotic biological preparation of Bacillus subtilis and Bacillus licheniformis on the fatty acid composition of the meat of broiler chickens of the research groups was established. The highest total content of saturated fatty acids to the total content of fatty acids in percentage was in experimental group 3 – 38.39 ± 0.002 %, which accordingly increased by 8.11 % compared to the control group (35.51 ± 0.002 %), due to the increase due to the increase in palmitic, stearic, iso-stearic content. The content of monounsaturated acids was characterized by the content of myrostolenic, palmitoleic, heptadeceneic, oleic, gondoic, and erucic nervonic acids. The highest content of monounsaturated fatty acids in experimental group 3 is 43.77 ± 0.002 % (Р≤0.001) due to an increase in the content of 43.77 ± 0.002 % (Р ≤ 0.001) of palmitoleic, oleic and gondoic acids. The increase in the content of polyunsaturated fatty acids in the meat of broiler chickens in experimental sample 3 was the highest – 25.16 ± 0.02 % (Р ≤ 0.001) due to the increase in the content (Р ≤ 0.001) of linoleic, linolenic and arachidonic fatty acids. The highest total content of omega-3 was in experimental groups of broiler chicken meat 2 and 3, respectively – 1.03 ± 0.001 % (Р ≤ 0.001) and 1.30 ± 0.001 % (Р ≤ 0.001) and omega-6, respectively – 22.98 ± 0.014 % (Р ≤ 0.001) and 23.40 ± 0.015 % (Р ≤ 0.001). The ratio ∑Omega-6/∑Omega-3 was – 22.31 and 18.00 in experimental groups 2 and 3, respectively. An increase in the relative biological value of meat (103.85 %) was observed when using Tetrachimena piriformis in a dose of the probiotic biopreparation Subtiform – 4.0 g/10 dm3 of water. The practical value of the research lies in the use of the probiotic biopreparation Subtiform to increase the biological value of meat and improve the amino acid and fatty acid profile.
