Freezing to −18°C for 7 d reduced numbers of Campylobacter jejuni in artificially contaminated hamburgers by one log cycle. Minimal cooking rapidly eliminated the organism. No Campylobacters were detected in 50 samples of commercial ground meat. Ground meat dishes such as hamburgers are therefore unlikely vectors for human Campylobacter enteritis. Freezing of artificially contaminated chicken carcasses greatly reduced or eliminated C. jejuni initially present at 105 cells/carcass. Minimal cooking for 20 min at 190°C eliminated all C. jejuni unless close pressing of limbs to the body preserved areas of uncooked skin. With commercial carcasses, 15/22 chilled and 6/37 frozen carcasses were contaminated with C. jejuni, maximum numbers being 105 and 103/carcass, respectively. Significant recontamination with C. jejuni could not be obtained by unhygienic handling after cooking of commercial chickens that had been moderately contaminated (103 to 104 cells/carcass), but substantial recontamination occurred with similar handling of carcasses that had initial heavy artificial contamination (106 cells/carcass). The limited circumstances under which cooked poultry meat is likely to carry C. jejuni in significant numbers suggest a need for caution in ascribing outbreaks of Campylobacter enteritis to consumption of poultry.

The priority route of entry of carcinogens into the body of the population of the Chelyabinsk region is oral, the leading medium for the transfer of xenobiotics is food, and the main carcinogen is arsenic, which comes from local agricultural products. The aim of the research was to study the mineral composition of semi-finished products from poultry meat from different manufacturing enterprises in the context of the environmental component of the safety of agricultural products. Chilled drumsticks produced by Nagaybaksky Poultry Complex LLC (Chelyabinsk Region, Nagaybaksky District, Farshampenuaz settlement) and Turbaslinskiye Broilers JSC (Republic of Bashkortostan, Blagoveshchensk) were used as objects of research. It was established that the maximum permissible concentration for arsenic was 3.7 times higher in the products of the Nagaybak poultry complex. Chromium was found more in semi-finished products from Bashkortostan (29 times), tin – in local raw materials. The drumsticks cooled from the Nagaybak processor significantly exceeded the competitor’s raw materials in terms of calcium (7.6 times), iron (2.9 times), zinc (2.1 times), selenium (2 times), phosphorus (1, 5 times), silicon (1.3 times), sodium (12.4%), as well as copper, manganese, molybdenum, tungsten, strontium. Relatively high levels of potassium (3.8 times) and magnesium (1.4 times), as well as aluminum, lithium, nickel, antimony, were recorded in the drumsticks of broiler chickens from a Bashkir producer. It was revealed that the semi-finished products of broiler chickens produced by Nagaybak Poultry Complex LLC did not comply with the requirements of Technical Regulation of the Customs Union 021/2011. The chilled shins of Bashkir production were recognized as safe within the framework of the current Technical Regulations.

The Cost

The main task in meat poultry production is to obtain products in a short period of fattening with the minimum feed costs. In economic terms, fodders occupy the largest share in the cost structure of poultry meat. The feed in its composition and properties should satisfy the physiological needs of the chicken, as much as possible, and this, in turn, directly depends on its usefulness and quality. In this regard, the actual issue of feeding is the use of antioxidants to improve the conservation of feed and optimize metabolism in the body of the bird. The inclusion of “Bisfenol-5” antioxidant in full-feed mixed doses in doses of 0.002-0.015% of the feed weight positively affected the growth rate of broiler chickens and feed conversion. The highest effect was obtained with the addition of “Bisfenol-5” in the amount of 0.008% to the compound feed. The use of antioxidant-enriched mixed fodder for growing chicken broilers allowed to increase meat production to 17.5%, to increase feed conversion to 12.1%, to reduce the cost of 1 kg of live weight gain to 6.99 rubles and to improve the efficiency index to 0.2 points.

Active Substances

In order to save the cost of expensive compound feed, a number of biologically active substances (vitamins and amino acids) and improve the digestibility of nutrients for the first time in poultry meat using laser technology there is a real possibility of “transferring” the studied amino acids (methionine, glycine) and all water-soluble vitamins using a laser beam through the skin in the breast area of broiler chickens. The research has been carried out in Belgrankorm-Veliky Novgorod LLC in the Krestetsky district in the Novgorod region with a large-cage housing method of broiler chickens of the cross Hubbard. The duration of broilers rearing was 39 days, 4 recipes of compound feed based on wheat grain, corn, soybeen meal with the inclusion of fish flour, sunflower oil, corn gluten, sunflower meal, meat and bone meal and mineral additives (monocalcium phosphate, lime flour) have been used. For better assimilation of nutrients and biologically active substances by the body amino acids (methionine, glycine) and water-soluble vitamins Undevit, both individually and in combination with them in a ratio of 1:1 (by weight), in the form of powders passed through an infra-red laser beam in a spatial modulator, which were attached to two emitters (simultaneously) of the “Uzor-2K-Super” laser in the chest area have been used. Broilers of the experimental groups ate feed more often and faster than the herdmates of the control group. Air ozonation in the poultry house and broilers has been carried out in a mobile way using the Rios ozonator of the Decont series (mode 3, with a capacity of 20 g/m3 ). Innovative methods of influencing on the body caused the increase in the intensity of metabolic processes, growth and development, fattening and meat traits, and feed conversion in broilers.

Abstract Increase in growth rate through genetic selection and improved nutrition in broiler chickens has been associated with high body fat deposition. This is particularly evident under ad libitum feeding that is normally practiced. Excessive fat deposition in the body of broilers is a common problem for poultry producers and consumers. Studies have shown that feed restriction could decrease fat content and increase protein deposition in carcasses, thus resulting in their improved composition. In addition to determining the optimal time to start and the duration of the restrictive nutrition, the success of the given programs largely depends on the intensity of the restriction, as well as the type of applied technique. Considering that in a large number of studies, the application of restrictive programs resulted in a reduction of body fat in broilers, but at the same time the desired body weight was not achieved at the slaughter (market) age, these programs should not be a priori rejected as ineffective. It is necessary to determine whether the market price of the obtained product (poultry meat) with its reduced fat content justifies the lower body weight of broilers achieved at the end of the fattening period.

Broiler Meat

It is known that necessary to replace the components of organic acids, which are part of acidifiers when drinking water to poultry in order to prevent the adaptation of microbes in the gastrointestinal tract. In the poultry industry organic acids are widely used, which are used as acidifiers to preserve the properties of water consumed. The purpose of this work was to evaluate the efficiency of broiler meat production when using acidifying agents of drinking water Aquasafe and Veleguard. The experimental part of the work has been performed in JSC “Kurinoe Tsarstvo-Bryansk” broiler area “Roshcha” in the Pochepsky district. The object of research was the livestock of broiler chickens cross Cobb 500 at floor housing. The effect of water acidifiers on meat productivity has been studied. Groups of chickens have been formed on the principle of pairs-analogues. Broiler chickens of experimental groups have been separated from the main livestock by a grid in the corner of the room for 100 heads in each group. It has been found by a result of research to be optimal dose usage of acidifying agents water Aquasafe and Veleguard to drink to broiler chickens. The positive effect of these acidifiers on the digestion of crude protein, crude fat, crude fiber, contributing to the effective use of nitrogen, which led to an increase in the intensity of growth, young animals’ livability and improved feed conversion. Slaughter yield in the control group was 55,1 %, and in the experimental group 57,2 and 58,4 %, which was by 2,1 and 3,3 % higher with the same level of metabolic energy and nutrients. In chickens that consumed acidifi ers more intensively used nutrients feed for deposition in the body of the components of the carcass, which affected the production. A positive impact of acidifying agents Aquasafe and Veleguard on meat quality in broiler chickens has been found.

The Impact

This article presents the results of studying the impact of housing and feeding conditions on broiler chickens of Hubbard RedBro cross, as well as the quality of products obtained when using floor and cage content, in a farm. It established that when receiving a mixed feed of own production using feed raw materials grown on a farm without the use of pesticides, a statistically significant decrease in potentially dangerous substances for animal health is recorded. Compared with factory feed, it has reduced the content of pesticides by 14 times, and mercury and arsenic by 24 times, cadmium by five times, and lead by ten times. The results of the study of economic indicators of growing Hubbard RedBro cross broiler chickens, as well as the chemical composition and quality of carcasses, indicated that there was no significant difference between the floor and cell conditions of keeping. Still, the use of a diet based on eco-feeds contributed to a statistically significant decrease in the concentration of toxic metals in the muscles of the poultry of the experimental groups. As a result, it found that the use of the studied compound feed in the diets of broiler chickens increased the indicators of Biosafety and ensured the production of environmentally safe ("organic") poultry meat products.

Human Infections

Campylobacter is the most frequent foodborne zoonotic bacteria worldwide, with chicken meat being overwhelmingly the most important reservoir for human infections. Control measures implemented at the farm level (i.e., biosecurity or vaccination), which have been successfully applied to limit other pathogens, such as Salmonella, have not been effective in reducing Campylobacter occurrence. Thus, new approaches are needed to fully understand the ecological interactions of Campylobacter with host animals to effectively comprehend its epidemiology. The objective of this study was to analyse longitudinally the gut microbiota composition of Campylobacter-infected and non-infected farms to identify any difference that could potentially be indicative of gut colonization by Campylobacter spp. Differences in the colonization rate and timing were observed at the farms that became positive for Campylobacter jejuni over the investigated time points, even though in positive tests, the occurrence of Campylobacter jejuni gut colonization was not observed before the second week of the life of the birds. Significant differences were observed in the abundances of specific bacterial taxa between the microbiota of individuals belonging to farms that became Campylobacter positive during the study and those who remained negative with particular reference to Bacteroidales and Clostridiales, respectively. Moreover, Campylobacter colonization dramatically influenced the microbiota richness, although to a different extent depending on the infection timing. Finally, a key role of Faecalibacterium and Lactobacillus genera on the Campylobacter microbial network was observed. Understanding the ecology of the Campylobacter interaction with host microbiota during infection could support novel approaches for broiler microbial barrier restoration. Therefore, evidence obtained through this study can be used to identify options to reduce the incidence of infection at a primary production level based on the targeted influence of the intestinal microbiota, thus helping develop new control strategies in order to mitigate the risk of human exposure to Campylobacter by chicken meat consumption.
