“…Currently, the technological standards providing for the rearing of large meat chickens on deep litter have been developed and tested [22,25]. However, the possibility of producing broiler meat for deep processing with the cage method of growing poultry, depending on the cross of poultry at a standard stocking density, has not been studied in detail [1,2,12]. In most cases, birds were observed to have breast folds, in connection with which studies on the assessment of the use of crosses of domestic and foreign selection for the production of large meat chickens in cages are relevant.…”

The article presents the results of a comprehensive assessment of the possibility of producing large meat chickens of domestic and foreign crosses with the cage method of growing, considering the separation by gender. The highest broiler productivity index was 213 units, which is by 27 units higher than when growing broilers of a foreign cross. The content of histidine is significantly higher in the meat of broilers of the domestic cross (by 0.50 g in the muscles of cockerels and by 0.54 g in the muscles of hens). It was found that it is advisable to produce large meat chickens using the domestic SK-Rus 613 cross for deep processing of individual parts of carcasses. The results are confirmed by the zootechnical efficiency of broiler production, the biological usefulness of the muscle composition and meat qualities, as well as the taste and aroma properties of meat products.

The article contains results of the research on the influence of "Sporothermin" probiotics and "Chiktonik" vitamin-amino acid complex on the processes of free-radical oxidation of lipids in the muscle tissue of fish. Three groups of sexually mature African catfish were formed. The first test group received "Sporothermin" probiotic at a dose of 2 g / kg of feed. The second group received "Chiktonik" vitamin-amino acid complex at a dose of 2 ml / kg of feed, the third group was the control and received only LimKorm "Som" brand feeds. All groups were tested for malondialdehyde content (MDA) in three months. In the control group, the content of MDA of males was 7948.71 mmol / 100 g of tissue, females - 8119.65 mmol / 100 g of tissue. Fish reared with the probiotics had the lowest levels of lipid peroxidation. Males had the MDA level of 3931.62 mmol / 100 g of tissue, and females - 4273.5 mmol / 100 g of tissue. As for the second group, which received “Chiktonik” vitamin-amino acid complex, the MDA content was lower than in the control, but higher than in the group which received the probiotics and was 4358.97 mmol / 100 g of tissue (males), and 4957.26 mmol / 100 g of tissue (females). It can be concluded that the usage of "Sporothermin" probiotics and "Chiktonik" vitamin-amino acid complex in the diet of African sharptooth catfish leads to a decrease of free radical processes, reduces the activity of lipid peroxidation, stimulates the antioxidant system, provides resistance to oxidative stress, revitalizing and increasing the vitality of the organism fish.

“…At the same time, this industry is the leading one in providing the population with a high-value and dietary product -broiler chicken meat [1][2][3][4][5][6][7][8][9]. An important link in the technological chain of meat production of broiler chickens is considered to be the parent flock, the keeping of which is constantly being improved, including on the basis of innovative equipment [10][11][12][13][14][15][16].…”

The aim of the study presented in this paper was to compare the reproductive qualities of laying hens of the parent flock of the ROSS 308 cross when using manual and automatic egg collection. The experimental part was carried out in the production conditions of a separate subdivision “Novosafonovskaya poultry farm” of Kuzbass Broiler LLC on laying hens of the parent flock of the ROSS 308 cross at the age of 155-435 days. The use of automatic nests for collecting hatching eggs did not affect the intensity of egg production, but contributed to an increase in the yield of hatching eggs due to a decrease in the culled eggs because of egg contamination, breakage, cracked shell and others. A decrease in the number of cleaned eggs among the hatching eggs contributed to an increase in the hatching of chicks and, as a consequence, an increase in the yield of day old chicks per initial layer by 11.9 heads or 8.5%.
