Intensive, market oriented pork and pork meat production requires detailed view of production prices, besides required quality and production parameters. This is required for meat-by products production to be economic in later phases. Previous results show that production price of fatteners does not vary during the year (around 1 ?/kg) because feed price does not very significantly. During the year supply and demand may change, so the price of fatteners changes. In conclusion, the position of live stock and meat producers is insecure and slaughterhouses supply with livestock and market with meat is unstable. The paper presents results of sides' quantitative parameters testing, economic analysis of profitability of supply of carcass sides according to quality and meat yield. Meat yield, basic parts and tissues in carcass sides was determined using partial dissection method. For economic analysis, divisional calculation was used. Base for cost distribution were relations between market prices of different meat categories and slaughter and pork meat processing costs in second phase of calculation. Carcass sides' weight was around 83kg. Average meat percentage was 47,96%, and it ranged from 42,5% (class O) to 52,2% (class U). Knowing that same production requirements are needed for both bad and good quality pigs, it is essential to stimulate fatteners' producers by paying for meat percentage using and classifying carcass sides on the pig slaughter line. Livestock producers can achieve greater price and adequate compensation for quality work on selection, choice of food, optimal fattening ending... At the same time producers of meat and meat by products, although they pay more for raw materials, they get better quality, more meat, and better economic effect. Customers are rewarded with better quality.

Background: In Vietnam, animal feed mainly depends on imported raw materials, while available agro-industrial by-products are often released into the environment and only a its unsubstantial portion used as an animal feed. Therefore, efficient use of these by-products as animal feed is essential. This work aimed to evaluate the effect of dietary levels of rice distiller’s dried grain (Rice DDG) on broiler performance, meat yield and meat quality. Methods: The research was conducted at the experimental station, Vietnam National University of Agriculture, Vietnam, from May to September 2020. A total of 240 a day-old broiler chicks were randomly assigned into 4 groups with 3 replications to receive 4 diets with different levels of RDDG at 0, 5, 8 and 10% for 14 weeks. Growth, meat yield and meat quality were estimated. Result: ADG was higher in broiler chickens fed diets with rice DDG compared to that in control diet at 12 and 14 weeks (P less than 0.05) while ADFI and FCR were not affected by the diets. There were significantly no differences in meat yield and quality among the diets. In conclusion, rice DDG could be used to partially replace main ingredients in chicken diets.

Modern hog breeding has a long tradition in the Czech Republic it is the stable branch of livestock production. Its main task is to produce high quality pork meat, which must meet all requirements of the processors and the final consumer. Pork meat occupies for decades in Czech Republic first place in consumption per one inhabitant (per year) and it forms more than 50% of the total annual meat consumption. This branch also plays an important role for producers of cereals, which largely contributes to the overall size and stability of the agricultural sector. The increasing imports were the main reason why many Czech hog breeding farms has been reduced or completely eliminated. Reducing numbers of pigs in the last decade is a reflection of supply and demand for pigs. The objecvive of this paper is to evaluate the changes in the cost structure for fattening of hogs and indicate how these changes are reflected in the competitiveness of Czech agriculture enterprises. Choice of optimal strategy of breeding and hog feeding already affects not only the requirements of food security, requirements of quality and affordability. Currently are also very important requirements for animal welfare and environmental protection with an emphasis on the sustainability of production and high hygiene standards. These measures require high investmens and operational costs are reflected in the worsening economy of pork meat production.

Primorsky Territory is a platform for the intensification of the livestock industry in order to provide the population with high-quality meat products. However, the introduction of new species of animals (yaks, camels, highly productive breeds of cattle) to the territory of the region contributes to the emergence and spread of invasions among them. Fascioliasis, dictyocaulosis, piroplasmidosis are natural focal parasitic diseases of animals that are widespread in the Primorsky Territory. They are detected almost every day during the veterinary and sanitary examination of animal slaughter products. Despite the absence of a threat of infection with these diseases for humans through meat and by-products, there remains a risk of deterioration in the quality of such products and the development of defects in meat raw materials, which leads to the impossibility of further sale and consumption. Yaks were brought to the Primorsky Territory in 2010 as an experiment, and in 2015, farmers actively used these animals as beef cattle, since their simplicity in keeping significantly reduced the cost of the meat production process. The conditions of keeping yaks in the Primorsky Territory contributed to their infection with parasitic diseases, the extent of the invasion of which reached 60% and more.

Current trends in meat and meat products exports are considered. The dynamics and structural changes in meat exports by types and degree of processing (beef and veal, pork, poultry, finished meat products) are analyzed. The paper proves that in recent years, only meat and edible poultry by-products have taken a competitive position in the world market. Accordingly, the dynamics of exports of this type of meat is positive, and the share of these products in the structure of exported meat is the largest (86.09%). Possible threats to the growth of import dependence on certain types of meat products, in particular, chilled and frozen beef and veal, pork, are indicated. The rating of the largest countries-importers of meat and meat products (by types) from Ukraine is built, their share in the structure of meat exports is determined. Changes in the geographical structure of exports have been studied, which indicate a low level of diversification of the geography of exports of certain types of meat (pork, beef). At the same time, a positive development of the geographical structure of poultry meat exports (exported to more than 100 countries) was revealed. Problems of the export potential development in the meat industry of Ukraine are revealed. In particular, the problems of livestock development (outdated technologies and production techniques that reduce the efficiency and productivity; inefficiency of the organization of purchase and processing of meat, which leads to reduced breeding in small businesses and households; inefficiency of state incentives, etc.) and industrial meat production (lack of raw materials, obsolescence of fixed assets and production technologies, poorly developed logistics, etc.). The solution of these problems requires: a systematic approach, which will encourage the cooperation of agricultural and industrial production, cooperation with importers of meat products and protection of domestic producers in the domestic and international markets, creating a favorable investment and information environment that will promote the meat industry development.

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.

The plastic industry is today facing a green revolution; however, biopolymers, produced in low amounts, expensive, and food competitive do not represent an efficient solution. The use of wine waste as second-generation feedstock for the synthesis of polymer building blocks or as reinforcing fillers could represent a solution to reduce biopolymer costs and to boost the biopolymer presence in the market. The present critical review reports the state of the art of the scientific studies concerning the use of wine by-products as substrate for the synthesis of polymer building blocks and as reinforcing fillers for polymers. The review has been mainly focused on the most used bio-based and biodegradable polymers present in the market (i.e., poly(lactic acid), poly(butylene succinate), and poly(hydroxyalkanoates)). The results present in the literature have been reviewed and elaborated in order to suggest new possibilities of development based on the chemical and physical characteristics of wine by-products.

Currently, the pork industry is incorporating in-line automation with the aim of increasing the slaughtered pork carcass throughput while monitoring quality and safety. In Korea, 21 parameters (such as back-fat thickness and carcass weight) are used for quality grading of pork carcasses. Recently, the VCS2000 system—an automatic meat yield grading machine system—was introduced to enhance grading efficiency and therefore increase pork carcass production. The VCS2000 system is able to predict pork carcass yield based on image analysis. This study also conducted an economic analysis of the system using a cost—benefit analysis. The subsection items of the cost-benefit analysis considered were net present value (NPV), internal rate of return (IRR), and benefit/cost ratio (BC ratio), and each method was verified through sensitivity analysis. For our analysis, the benefits were grouped into three categories: the benefits of reducing labor costs, the benefits of improving meat yield production, and the benefits of reducing pig feed consumption through optimization. The cost-benefit analysis of the system resulted in an NPV of approximately 615.6 million Korean won, an IRR of 13.52%, and a B/C ratio of 1.65.

The Impact

China’s wood industry is vulnerable to the COVID-19 pandemic since wood raw materials and sales of products are dependent on the international market. This study seeks to explore the speed of log price recovery under different control measures, and to perhaps find a better way to respond to the pandemic. With the daily data, we utilized the time-varying parameter autoregressive (TVP-VAR) model, which can incorporate structural changes in emergencies into the model through time-varying parameters, to estimate the dynamic impact of the pandemic on log prices at different time points. We found that the impact of the pandemic on oil prices and Renminbi exchange rate is synchronized with the severity of the pandemic, and the ascending in the exchange rate would lead to an increase in log prices, while oil prices would not. Moreover, the impulse response in June converged faster than in February 2020. Thus, partial quarantine is effective. However, the pandemic’s impact on log prices is not consistent with changes of the pandemic. After the pandemic eased in June 2020, the impact of the pandemic on log prices remained increasing. This means that the COVID-19 pandemic has long-term influences on the wood industry, and the work resumption was not smooth, thus the imbalance between supply and demand should be resolved as soon as possible. Therefore, it is necessary to promote the development of the domestic wood market and realize a “dual circulation” strategy as the pandemic becomes a “new normal”.
