The prospect of using chicken breeds of the combined type of productivity in organic poultry farming

Abstract

Relevance. The demand for organic meat products is constantly increasing. Organic agriculture is the leading global trend. The organic market for 2020 is estimated at $ 130 billion with an annual growth of 13–15 %. During the pandemic, sales of organic products in developed countries increased by 30–40 %. Methods. The object of the study were chickens of the Pushkin breed and the Ross 308 cross (broiler). The birds were grown up to 85 days of age under the same conditions, the stocking density was 10 birds/m2. At the age of slaughter in industrial production (48 days – broiler) and organic production (85 days) according to the methodology of the All-Russian Research and Technological Institute of Poultry (2001), anatomical cutting of 9 heads was carried out. Analysis of quality indicators of meat by high performance liquid chromatography (M02-902-142-07) was carried out in the certified laboratory «Leningradskaya MVL». Dry matter was determined by the express method according to the Rygalova E. A. and the water binding capacity of meat was determined by the Grau – Hamm method in the Volovinskaya – Kelman modification. Results. Extending the fattening period of broilers to 85 days to meet the requirements of organic poultry farming does not sufficiently improve the quality of their meat. Low livestock safety (58.16 %) reduces the profitability of organic broiler production. An increase in the total protein content from 20.44 % to 24.41 % and amino acids (tryptophan and prolin), as well as a decrease in fat content from 5.1% to 1.35 % in the pec-toral muscle of broiler chickens from 45th to 85th day improves the dietary qualities of broiler meat. However, a decrease from 51.46 % to 48.54 % of the water-binding capacity of meat reduces its taste and techno-logical qualities. In chicken of the Pushkin breed this figure is 51.35 %. Thus, using the example of the Pushkin breed of chickens, it is shown that breeds of the combined direction of productivity are more suitable for long-term cultivation in organic poultry farming for obtaining meat products.
