The second for the significance livestock sector is pig breeding, which accounts for one-third of the country’s meat production. Long-term world practice of pig farming confirms the high maturity of this species of animals, excellent taste, nutritious meat and most importantly the ability to quickly increase food production, and thereby ensure the optimal balance of the diet of the population. One of the constraining factors for the development of this industry is the development of iron deficiency alimentary anemia in pigs during the first 7 days of animal life, which affects the growth, development and increase of live weight in animals. Without preventive measures to supplement the iron with animals, up to 100% of piglets become sick with anemia, which can lead to the death of a significant part of the young population. This article presents the results of the toxicological approbation of a new iron-containing preparation for farm animals. The question of finding a less toxic iron preparation with a higher prolonging effect is relevant.

The development of industrial poultry farming requires not only the breeding of new highly productive poultry breeds, but also the development of new rearing technologies and the improvement of standardized nutrition. Currently, in the field of feeding farm animals and poultry an important research area is the search for cheaper non-traditional and affordable feed products that can replace part of the grain in the poultry diet. It is very important to use local raw materials. One of these crops is naked oat, which has the highest energy content, the highest concentration of lysine and methionine among all cereals. The purpose of the researches was to determine the eff ectiveness of using naked oat in compound feed for quails. The results of the influence of complete nutrient-balanced compound feeds with naked oat on zootechnical and economic indicators in the rearing of quails have been presented in the article. It has been found that the live weight of quails in the experimental group has been increased by 3,06 %, while the average daily feed consumption has been increased by 1,83 %. Feed expenditures per 1 kg of live weight gain in the experimental group have been lower by 1,31 % due to the absorption of feed nutrients. According to the results of the balance experiment, the digestibility of raw protein has increased by 1,90, fat by 0,41 %, nitrogen-free extractive substances by 2,77 %. When calculating economic indicators, it has been found that the use of naked oat in compound feed for quails allowed to increase the yield of meat and revenue from its sale by 3,75 %. Despite an increase in the total cost of feed consumed by the experimental group by 2,27 %, the profi t has been received by 9,59 % more. The level of profi tability of quail meat production in the experimental group exceeded the indicator of the control group by 3,40 %.

An experiment has been conducted to determine the effectiveness of growing broiler chickens when whole wheat grain has been included in the compound feed. The purpose of the research was to develop an appropriate scheme and dose for feeding whole wheat grain depending on the age of broilers, while observing the normative content of metabolic energy and nutrients in the diets, and to determine the economic effectiveness of rearing of broilers. To determine the effectiveness, data on live weight, growth rate, livability, uniformity of broiler population by live weight and variability of live weight of chickens have been studied. In the course of the work, the livability, average daily gain, feed conversion, homogeneity and variability coefficients, and the productivity index have been calculated. An increase in the live weight of broilers, as well as the rate of growth in pre-slaughter age when using whole grains in poultry diets, as well as a decrease in feed consumption per unit of live weight gain has been revealed. In conclusion, the economic effectiveness of broiler meat production has determined when whole grain has been included in diets. The use of whole wheat grain as an additive to the main diet in broiler feeding allowed to increase profits and increase the level of profitability. It has been found as a result of research that it is advisable to add whole wheat grain to the main diet for broilers at the age of 8–14 days in an amount of 5 % of the feed weight, at the age of 15–21 days – 15 %, at the age of 22–28 days – 20 %, at the age of 21–29 days – 30 % of grain without reducing the overall nutritional value of the diet.

Farm-animal species play crucial roles in satisfying demands for meat on a global scale, and they are genetically being developed to enhance the efficiency of meat production. In particular, one of the important breeders’ aims is to increase skeletal muscle growth in farm animals. The enhancement of muscle development and growth is crucial to meet consumers’ demands regarding meat quality. Fetal skeletal muscle development involves myogenesis (with myoblast proliferation, differentiation, and fusion), fibrogenesis, and adipogenesis. Typically, myogenesis is regulated by a convoluted network of intrinsic and extrinsic factors monitored by myogenic regulatory factor genes in two or three phases, as well as genes that code for kinases. Marker-assisted selection relies on candidate genes related positively or negatively to muscle development and can be a strong supplement to classical selection strategies in farm animals. This comprehensive review covers important (candidate) genes that regulate muscle development and growth in farm animals (cattle, sheep, chicken, and pig). The identification of these genes is an important step toward the goal of increasing meat yields and improves meat quality.

This review attempted to collate and synthesize information on goat welfare and production constraints during heat stress exposure. Among the farm animals, goats arguably are considered the best-suited animals to survive in tropical climates. Heat stress was found to negatively influence growth, milk and meat production and compromised the immune response, thereby significantly reducing goats’ welfare under extensive conditions and transportation. Although considered extremely adapted to tropical climates, their production can be compromised to cope with heat stress. Therefore, information on goat adaptation and production performance during heat exposure could help assess their welfare. Such information would be valuable as the farming communities are often struggling in their efforts to assess animal welfare, especially in tropical regions. Broadly three aspects must be considered to ensure appropriate welfare in goats, and these include (i) housing and environment; (ii) breeding and genetics and (iii) handling and transport. Apart from these, there are a few other negative welfare factors in goat rearing, which differ across the production system being followed. Such negative practices are predominant in extensive systems and include nutritional stress, limited supply of good quality water, climatic extremes, parasitic infestation and lameness, culminating in low production, reproduction and high mortality rates. Broadly two types of methodologies are available to assess welfare in goats in these systems: (i) animal-based measures include behavioral measurements, health and production records and disease symptoms; (ii) resources based and management-based measures include stocking density, manpower, housing conditions and health plans. Goat welfare could be assessed based on several indicators covering behavioral, physical, physiological and productive responses. The important indicators of goat welfare include agonistic behavior, vocalization, skin temperature, body condition score (BCS), hair coat conditions, rectal temperature, respiration rate, heart rate, sweating, reduced growth, reduced milk production and reduced reproductive efficiency. There are also different approaches available by which the welfare of goats could be assessed, such as naturalistic, functional and subjective approaches. Thus, assessing welfare in goats at every production stage is a prerequisite for ensuring appropriate production in this all-important species to guarantee optimum returns to the marginal and subsistence farmers.

The importance of chemical products in todays society is known, which can increase food production, improve the quality of life and extend the lifespan. However, their dangers are also obvious. In addition, a large number of chemical accidents, that produce chemicals, continue to take place in the chemical industries in spite of the great improvement in the safety management standard of worldwide chemical industries. Such accidents are taking place not only in the developing countries, but also in developed countries, which result in a lot of property loss, death and serious environmental issues with long term negative effects. Therefore, how to live with these substances and how to handle, use and dispose them safely have attracted much attention because chemical safety and risk management of chemicals have formed an international challenge.

Pig breeding is one of the key areas for the development of livestock meat production both in Russia and in the world. According to forecasts of various agro-industrial companies and information and analytical agencies, by the end of 2020, pork production was predicted to grow similar to that in 2019, which was 5,1% (or more than 192,6 thousand tons, in slaughter weight, compared to 2018). This would represent more than a third of the total meat production in Russia, which was estimated at 11,04–11,22 million tons (as compared to 10,9 million tons in 2019). According to preliminary data from the Ministry of Agriculture of the Russian Federation (dated February 4, 2021), pork production increased "at 8.9% by 2019, which in live weight is +446 thousand tons", while the total meat production in Russia in 2020 reached 15,6 million tons, an increase of 3,1% (+472 thousand tons) more than in 2019. These indicators significantly exceed the forecasts indicated above, which is associated with the implementation of investment projects (primarily with state participation) in this direction and "expansion of export opportunities for Russian suppliers" in 2020. Despite the sanctions, coronavirus and other global challenges to the Russian economy, pork has been the "main driver" for the growth of meat production in Russia in recent years. Now our country is on the 4th line in the ranking according to the pig numbers (46.5 million heads in 2019) after China, the European Union and the United States of America. Agricultural enterprises in Russia account for 83,4% of pigs, 14,6% – on personal subsidiary plots, 2,0% – on farms. According to experts, the long-term development trend is an increase in the number of pigs in 5 years by 27,7%, in 10 years – by 36,1%, and the annual increase in pork production is planned at about 5%. Thus, in recent years, pork production has determined a positive trend in all domestic livestock farming in terms of the volume and quality of meat produced in Russia.

Bovine insulin-like growth factor 1 (IGF1), thyroglobulin (TG), diacylglycerol-O-acyltransferase 1 (DGAT1) and myogenic factor 5 (MYF5) genes play an important role in the physiology of lipid and muscle metabolism and are therefore considered as candidate genes for meat production traits in farm animals. The objectives of this study were to investigate single nucleotide polymorphisms (SNPs) in IGF1, TG, DGAT1 and MYF5 genes and to evaluate whether these polymorphisms affected meat colour, tenderness and cooking loss in Holstein cattle. Initially, the SNPs were detected by polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) method. Meat samples (N= 50) derived from M. longissimus thoracis et lumborum (LTL) were used in the current study. Significant differences in variations of meat colour parameters were observed at 24 hours post-mortem. IGF1 was associated with colour parameters of a* and chroma values. In addition, effects of TG were statistically significant on L* and a* values, while, effects of MYF5 were significant on a* value. There was no association of the tested SNPs with meat pH, tenderness and cooking loss. The results presented here may give the valuable information for improving meat colour in cattle.
