“…Poultry farming is a branch of animal husbandry, the purpose of which is to breed a healthy poultry inventory [1][2][3][8][9][10][11][12]. Poultry farming uses meat-breed chickens, although other types of poultry such as ducks, geese, turkeys, guinea fowls have recently become popular.…”

The article indicates that further development of poultry farming is due to the optimization of the feed base associated with the use of effective veterinary feed additives having a positive effect on the health and average daily weight gain of young poultry. When choosing imported market products, a correctly selected HS code is of great importance, which allows reducing the delivery time of vitamin preparations and vitamin-mineral complexes, which favorably affect the growing time and quality indicators of the quality of products obtained.

“…In addition, determining heavy metal levels in bird feathers has also helped monitor the heavy metal contamination of territories [ 29 , 30 ]. Earlier published studies found that the levels of trace elements in feathers largely reflect the exchange pool of the main essential and toxic elements in broilers and laying hens [ 31 , 32 ]. Simultaneously, the amount of available information on the content of microelements in the feather of birds, particularly laying hens, is limited at different periods of ontogenesis.…”

Background and Aim: Micronutrient imbalances pose a severe threat to the health and productivity of livestock and poultry. In this regard, a further stage in feeding science development will control and optimize the intake of mineral substances, including determining the elemental composition in some biosubstrates. One of these biosubstrates can be a feather. However, the amount of available information on the content of trace elements in laying hens is limited, complicating the laboratory data interpretation. Therefore, this study established reference intervals for the concentrations of the main essential and toxic elements in laying hens in different periods of ontogenesis. Materials and Methods: The study was conducted on clinically healthy Hisex Brown laying hens at the age of 10 (n=150), 30 (n=150), 120 (n=150), 150 (n=150), and 210 (n=150) days. All examined birds were born and raised on the territory of the South Ural biogeochemical province of Russia. The sampling of feathers was carried out by plucking the flight feathers of the wing. Inductively coupled plasma dynamic reaction cell mass spectrometry determined the elemental composition of the feather according to 25 parameters. Results: The results showed that at the minimum age (10 days), the highest concentrations of chemical elements were observed in laying hens. Subsequently, as they grew older, in the period from the 30th to the 120th day, there was a significant decrease in these indicators. Later, from the 120th to the 150th day, a statistically significant increase in concentrations was replaced. Little growth and relative concentration stability were observed in the last part of the experiment (150-210 days). Chemical element concentrations in feathers were computed in reference ranges for each age group. Conclusion: The calculated ranges of chemical element concentrations in laying hens can be used to compile norms for their content in the body; however, it is worth noting that these ranges can vary depending on the biogeochemical province of breeding and the bird's age.

“…In many countries of the world, feed antibiotics have been replaced by environmentally safe biological preparations: probiotics, prebiotics, phytobiotics and others [5,6,7,8,9,10,11]. It is noted that such additives can simultaneously stimulate the digestibility and use of nutrients in the feed.…”

The article presents the results of studying the impact of the spore-forming probiotic “Olin” and the prebiotic “Eсofiltrum” on the meat quality of broiler chicken carcasses of the Ross-308 cross. In the course of the research, it has been found that the inclusion of these preparations in the broiler diet has a positive effect on the studied indicators: the pre-slaughter weight increased by 4.3-5.7%, the weight of the gutted carcass by 4.6-6.2%, the muscle weight 4.8-6.5%, the weight of the loin muscles by 5.7-8.2%. The ratio of edible parts to inedible parts is 4.14 in the third experimental group, 4.08-in the second, and 4.04-in the control. Based on the results of the anatomical cutting of broiler carcasses and according to the fatness indicators the poultry carcasses of the third and second experimental groups, 87.5% and 87.2%, respectively, belong to the first grade, and the yield of the first grade carcasses is 86.2% in the control group. Meat products obtained from both the control poultry and the poultry of both experimental groups has no off-aroma odor and taste, the meat is juicy, tender and aromatic. The products obtained from broiler chickens, whose ration includes the probiotic “Olin” and the prebiotic “Ecofiltrum”, do not have any deviations from the established standards and norms. During the research, it has been found that the use of the studied drugs has a positive effect on the meat quality of poultry carcasses. However, broiler chickens receiving the probiotic “Olin” has more pronounced meat qualities.
