On a worldwide basis increasing of meat production, especially beef, improving of its quality and reducing of costs are of great economic importance, and therefore intensification of livestock industry through introduction of advanced technologies, organization of full feeding, creation of optimal conditions for animals' welfare, breeding of the most productive breeds of young cattle are important. Young cattle of various productivity areas in Russia are grown to different weight conditions with different technologies of keeping and battening and their live weight and carcass weight are evaluated according to the interstate standard GOST 34120-2017 according to 7 categories. In 2018 production of livestock and poultry for slaughter (live weight) in farms of all categories in Russia amounted to 9 million tons and increased by 3.7 % compared to the same period in 2017. According to the Russian State Statistics of Federal Agency the volume of industrial meat production amounted to 1 690.6 thousand tons for the period from January till August in 2018 (11.2 % more than at the same period in 2017). Agricultural organizations produced 626.1 thousand tons of meat for the period from January till August in 2018 (almost 8 % more than at the same period in 2017). In 2018 according to the data from the Russian Ministry of Agriculture the average price of agricultural producers for cattle (live weight) was 109.57 thousand rubles per ton (w/o VAT), for half-carcass beef-209.25 thousand rubles per ton (w/o VAT), which are also higher compared to the data for 2017. Average consumer costs for beef-325.91 rubles per kg. In this work comparative assessment of average purchasing and consumer prices of live weight and carcasses of bulls and bullocks of various productivity areas was made, taking into account age of animals and technology of growing and battening by the category-super, prima, extra, excellent, good, satisfactory, low and evaluation of economic prospects for growing young stock to different weight conditions was given.

There is constant necessity of developing the accurate and fast methods for detection of foodborne pathogens. Microorganisms of Campylobacter genus are one of the main causes of foodborne diseases worldwide. Fast identification of Campylobacter at all stages of the food life cycle is an efficient strategy to control foodborne campylobacteriosis. This article the authors evaluated a commercial loop-mediated isothermal amplification (LAMP) system with bioluminescence, called as the 3M™ Molecular Detection Analysis (MDA), which was used to find Campylobacter in food products with the help of a certain standard method, which is referred to as the reference method. The results of this study showed that the commercial LAMP based method is as efficient as the reference method, and features high specificity and minimum determinability (sensitivity). The LAMP based method has been shown to be a fast and reliable method for detection of Campylobacter spp. scarce presence (10 CFU/25 g) in meat, meat products, as well as carcass swabs and production facilities’ environment. The LAMP analysis required about 24–27 hours to achieve a result. However the LAMP based method will facilitate the detection of Campylobacter, as it provides much easier and faster detection of Cam  pylobacter spp., including Campylobacter jejuni/Campylobacter coli, than standard microbiological methods. The LAMP based method is an efficient tool to prevent the spreading of Campylobacter spp. contamination in food products.
