From January 1997 to May 1998, 772 samples of poultry carcasses and poultry products for sale on the retail market in Belgium were analyzed for the presence of Salmonella spp., Salmonella Enteritidis, Campylobacter jejuni, C. coli, and Listeria monocytogenes per 100 cm2 or 25 g. Poultry samples were contaminated with Salmonella (36.5%), C. jejuni and C. coli (28.5%), and L. monocytogenes (38.2%). In about 12.3% of the poultry samples, the L. monocytogenes contamination level exceeded 1 CFU per g or cm2. Significant differences in pathogen contamination rates of poultry products were noticed between the poultry products originating from Belgian, French, and U.K. abattoirs. Poultry products derived from broiler chickens running free in pine woods until slaughtering age (12 to 13 weeks) had a significantly (P < 0.05) lower contamination rate of Salmonella than poultry products from enclosed broilers slaughtered at the age of 6 to 8 weeks. A significantly (P < 0.05) lower pathogen contamination rate was noted for Salmonella, C. jejuni, and C. coli for poultry cuts without skin compared to poultry cuts with skin on. An increase in pathogen contamination rate was noticed during cutting and further processing. To diminish C. jejuni, C. coli, Salmonella, and L. monocytogenes contamination rates, hygienic rules of slaughter and meat processing must be rigorously observed. At the moment, zero tolerance for these pathogens is not feasible, and there is a need to establish criteria allowing these pathogens to be present at reasonable levels in the examined poultry samples.

ABSTRACTCampylobacteris a leading cause of bacterial gastroenteritis in humans and is often linked to contaminated poultry products. LiveSalmonellavectors expressing three linear peptide epitopes fromCampylobacterproteins Cj0113 (Omp18/CjaD), Cj0982c (CjaA), and Cj0420 (ACE393) were administered to chicks by oral gavage on the day of hatch, and the chicks were challenged withCampylobacter jejunion day 21. All three candidate vaccines produced consistent humoral immune responses with high levels of serum IgG and mucosal secretory IgA (sIgA), with the best response from the Cj0113 peptide-expressing vector.Campylobacterchallenge following vaccination of three candidate vaccine groups decreasedCampylobacterrecovery from the ileum compared to that for controls on day 32. The Cj0113 peptide-expressing vector reducedCampylobacterto below detectable levels. TheSalmonella-vectored Cj0113 subunit vaccine appears to be an excellent candidate for further evaluation as a tool for the reduction ofCampylobacterin poultry for improved food safety.

The authors considered organic poultry production and presented a qualitative analysis of the diets used in raising broiler chickens. The authors also evaluated the possibility of switching from traditional diets to diets without chemical and microbial synthesis ingredients based on comparative data on the performance and economics of broiler chicken meat production. Organic requirements prohibit the use of microbial and chemical synthesis and genetically modified products in poultry feed. Obtaining large quantities of poultry products in a short period and at an affordable price involves using all kinds of additives that do not allow the products to qualify as organic. Surveys and opinion polls show that a new layer of consumers is today willing to buy organic poultry meat at a higher price. The aim of this work is to evaluate the possibility of producing organic meat from broiler chickens. The research was carried out at the Berdskaya poultry farm, and the test object was broiler chickens of the Iza cross. The age of broiler chickens ranged from one to 40 days old. The authors compared the effectiveness of traditional industrial diets and diets without microbial and chemical synthesis products. During the experiment, live poultry weight, average daily and gross gains, survival, feed costs and cost-effectiveness were considered. In commercial broiler chickens raised on diets without chemical and microbial synthesis ingredients during slaughter, the average live weight was 64.0% lower than that of broiler chickens in the experimental group. The average daily gain of these same broilers was also 52.9% lower. Feed costs per unit of production in industrial broiler chickens increased 1.7 times with the same survival rate of young animals (92.2%). Increasing the rearing period to 70 days resulted in a 1.4-fold increase in feed costs. The level of profitability decreased by 61.2 %, with a decrease in productivity. Increasing the price per kg of meat by 25 50 100 % would increase the profitability level by 22.4 4.7 -133.5 %, respectively, compared to the traditional method.

With the increase in consumption of poultry products, the requirements for their quality, especially for nutritional and biological value, also increased. As the experience and scientific achievements of recent years shows, these indicators are quite manageable, that is, you can create products with predetermined properties. The aim was to study the combined use of chlortetracycline and Quercus cortex extract. The quantitative ratios of lipids and fatty acids in poultry meat are the main criteria of its quality, and fatty acids are of great importance. Together with essential polyunsaturated fatty acids, the composition and quantitative content of saturated fatty acids are of great importance in the muscle tissue, it plays an important role in providing the necessary ratio of unsaturated and saturated compounds. Under the influence of chlortetracycline and Quercus cortex extract, ambiguous changes in fatty acid composition are observed; primarily, it is due to changes in enzymatic complex of poultry digestive tract and changes in the intestinal microflora. Based on the conducted research, it can be concluded that fatty acid composition of broiler chickens can be corrected adding antibiotic in different ratios and concentrations together with Quercus cortex extract.

Poultry farming, providing replenishment of the food basket with high-quality and inexpensive products, plays an important role in the formation of food security in Russia. Veterinary and sanitary examination of poultry products in the context of the ecological component of the safety of agricultural raw materials is an important and timely task within the framework of government documents of the Russian Federation in the field of health protection of the country's population. According to the results of the physical, chemical and microbiological tests of chilled broiler chicken carcasses of the 1st grade of the Ural processors («Ravis – Sosnovskaya poultry farm», «Argayashskaya poultry farm», «Nagaybak poultry complex»), the raw materials were recognized as fresh, in terms of the amount of pesticides, antibiotics and heavy metals – safe. The content of protein, fat and moisture in all studied samples corresponded to the average values. A detailed study of the mineral composition revealed negative deviations in the amount of Fe and Se in all carcass samples. The products of the Argayash poultry farm against the background of analogous samples contained less fat and moisture with identical protein values, occupied an intermediate position in the amount of essential elements – Ca, Fe, Na, P, Zn, was distinguished by the absence of minerals that increase the toxic load on the human body – Ni, Ti , Ba, Ga, Li, which formed its competitive advantages.

Pasture rearing is an increasingly common option for small farms to produce humanely raised poultry products for an expanding market, however profit margins tend to be much lower for pastured poultry producers than for those that opt for conventional indoor rearing. Research into simple methods to optimize the growth and health of pasture-raised poultry can help small farmers maximize meat yields and decrease the morbidity and mortality of their flock, ultimately leading to higher profit margins and improved animal welfare. The objective of this study was to measure how the inclusion of mature, native foliage into pastures can impact the production performance and overall health status of two different popular breeds of commercial broiler chickens; fast-growing Cornish cross and slower growing Red rangers. During the finisher phase (30–78 days old), pastured chickens were separated by breed into either a treatment population with access to a mature bordering hedgerow, or a control population without access to a hedgerow. Weekly weight gain, daily feed intake and basic hematologic values were used to evaluate differences in the production performance and health status between each population. We found that hedge access led to a significant improvement in the rate of gain of the Cornish cross without an associated increase in feed intake, suggesting that the addition of hedges can increase meat yields in fast-growing broilers without increasing feed costs. Red rangers with hedge access demonstrated an improved ability to neutralize bacterial pathogens in whole blood and a lesser degree of hemodilution compared to control populations, suggesting improved immune function and a lower degree of heat stress in these populations. We conclude that the addition of natural environmental enrichment such as mature foliage to grass pastures can lead to improved production performance in fast-growing broilers and improvements in the health and immune function of slower growing broiler chickens.

This research; The purpose of this study was to determine the effect of the media on the consumer preferences of broiler meat consumption in different regions, different age, income, education level and occupational groups. For this purpose, a total of 1350 (Kayseri 500, Sivas 450, Yozgat 400) sample face-to-face surveys were conducted on three villages in Kayseri, Sivas and Yozgat provinces (TR 72 Region). In the study, the sample volume was determined by simple one-pass random sampling method based on the population ratios. The change in the impact of poultry-related negative media coverage on the consumption of poultry products has been examined on the TR72 region basis. In terms of the rate of followers of poultry news, the three provinces differ significantly from each other, and in general, about 75% of the individuals follow news about poultry. Percentage of people who think that the feeding of broiler chickens is not healthy is 60.4% on average, and regional differences are found significant in this value. The proportion of those who were affected by media news and reduced the amount of poultry consumption was 36.1%, with regional differences being significant. Negative news in the media about poultry sector was effective enough to cause marketing problems in this area, consumers were following these news at a high rate, while using media tools, more effective promotion and information had to be done.

The Creation

Abstract The creation of a new cross “Smena-9” is aimed at reducing import dependence in the production of poultry products. In order to assess the meat raw material potential, morphological indicators of gutted carcasses of broiler chickens of the Smena-9 cross and individual parts were determined. The research used 5 carcasses of broilers from a batch of 38 days of age, weight, g: 1457.80; 1487.50; 1508.10; 1548.20; 1567.0. Separate parts – chest, thighs, drumsticks, legs and wings were anatomically divided into their components [muscles, skin, fat and bones with a residual lump]. The results of the experimental part of the research are reduced to average indicators: the average weight of a gutted carcass, individual parts and their components. It was found that the yield of the breast part is 36.0% [meat tissue 30.9%], the yield of the drumsticks – 29.9% [thighs – 16.45%, legs – 13.45%], wings – 10.75%, while flesh makes up 30.9%, 24.9%, and 7.8%, respectively, which exceeds the same indicators of domestic crosses. It was determined that the total yield of the breast and legs of the Smena-9 cross [65.9%] is higher by 5.3% for carcasses weighing 1600 g and by 8.8% for carcasses weighing 1850 g; for flesh, the excess is 5.8% and 5.2%, respectively. The obtained results serve as the basis for the development of normative documentation for parts of carcasses and their components of the Smena-9 cross and a system for assessing the effectiveness of equipment for cutting and deboning by the degree of approximation of the results of its operation to similar indicators for anatomical cutting and deboning.

Campylobacter jejuni is the most common bacterial cause of diarrheal disease in humans worldwide, with poultry products being a major source. Therefore, strategies to decrease Campylobacter colonization during primary production might aid in reducing the number of human campylobacteriosis cases. Several plant-derived compounds have been reported to possess anti-Campylobacter properties in vitro, so they could be promising candidates to reduce Campylobacter colonization in broiler chickens. To test this hypothesis, selected plant-derived antimicrobials (caffeic, gallic, protocatechuic, and vanillic acids, epigallocatechin gallate, trans-cinnamaldehyde, and thymol) were screened for anti-Campylobacter activity by determining MICs and setting up time-kill curves for C. jejuni strain KC 40. These experiments revealed marked antibacterial activity, especially for the cinnamon oil ingredient trans-cinnamaldehyde (CIN). This compound was tested in a broiler chick seeder model; it was added to the feed in coated form at an effective concentration of 0.3% from day-of-hatch for the entire 22-day duration of the experiment. At 14 days of age, one-third of the birds were inoculated with C. jejuni strain KC 40 and served as seeders. CIN was not able to reduce cecal Campylobacter colonization in this model, which was confirmed in a cecal loop experiment. Despite CIN concentrations much higher than the MIC, C. jejuni numbers were not reduced compared with those in nontreated ceca at 2 and 24 h after injection. In conclusion, this study shows a marked discrepancy between in vitro and in vivo activity of CIN against C. jejuni strain KC 40.
