Abstract

The article presents the results of the effect of partial replacement of mixed feeds with organic concentrate based on dry bird droppings (DBD) on the preservation of quail, quantitative and qualitative rates of egg productivity. For the laboratory experiment, 5 experimental groups of Manchurian quail were formed by the analogous pair comparison method. The quail of the control group consumed all-in-one feed (AF), for the quail of the experimental groups (I, II, III, and IV) part of the AF – 10, 15, 20 and 25 % by weight – was replaced with organic concentrate. Results of studies reveal that the introduction of 10 % of organic concentrate into the AF contributed to improved feed intake and livestock safety, increased egg productivity and reduced feed consumption per unit of output. With respect to the indicators of biological usefulness, toxicological and sanitary-epidemiological safety, quail eggs treated with the organic concentrate met the requirements of GOST and TR TS 021/2011 “On food safety”.

Highlights

Industrial poultry farming is the most intensively developing agricultural sector in many countries of the world, providing the population with highly nutritious and affordable food [1, 2]
Quail of the control group was fed with factory-produced mixed feed DK-52 – 100 %, and 10 %, 15 %, 20 % and 25 % of organic concentrate based on dry bird droppings (DBD) was introduced into the diets of quail of experimental groups (I, II, III and IV) in exchange for a similar amount of the main diet
Based on the data of the table, it is noted that the addition of up to 25 % of organic concentrate based on DBD to mixed feeds did not have a negative effect on feed intake, there was no significant difference between the groups in terms of feed intake

Summary

Introduction

Industrial poultry farming is the most intensively developing agricultural sector in many countries of the world, providing the population with highly nutritious and affordable food [1, 2]. When preparing all-in-one mixed feeds for poultry, foddergrain crops (corn, wheat, barley, oats, millet) are being increasingly used. Their proportion in mixed feed reaches 65–80 % by weight [3, 4]. The observed population growth causes an increased demand for fodder-grain crops, resulting in their cost increase and the decrease of profitability of poultry farming. In this regard, many researchers are looking for alternative cheaper sources of energy and protein for poultry [5, 6]. Crude protein is represented by a complex of essential amino acids, ( %): glycine 1.1–1.3; aspartic acid 1.01–1.02; glutamic acid 1.2–1.3; lysine 0.7–0.8; phenylalanine 0.7–0.8; leucine 0.67–0.85; valine 0.6; serine 0.5–0.7; threonine 0.5–0.6; isoleucine 0.4–0.5; phenylalanine 0.36–0.45; arginine 0.35–0.42; proline 0.2–0.3; tyrosine 0.17–0.20; histidine 0.15–0.20. 100 g of DBD contains (mg): iron 367–900; zinc 12–39; manganese 15–38; copper – 0.5; cobalt 1.0–1.2 [7, 8]
