Abstract

Agriculture modernization is a topical issue for both the global and domestic economy. Intensification of livestock farming results in an increased production of manure. Recycling of manure into bedding is one of the modern utilization technologies. National regulations do not specify requirements for currently applied bedding types, including manure-based bedding. The foreign experience, however, demonstrates several economic, zootechnical and hygienic advantages of this material. The field veterinary study revealed the positive health effect of bedding. The cows housed without bedding featured threefold higher risk of surgical diseases of limbs. Technical and economic assessment of a dairy farm with 1000 dairy cows showed the following annual operating costs when the major part of manure was passively composted and a part of manure was recycled into the bedding by (1) aerobic solid-state fermentation in a chamber fermenter and finish drying in a dryer drum – 24.2 million roubles; (2) aerobic solid-state fermentation in a drum fermenter – 21.7 million roubles; and (3) thermal drying in a dryer drum – 27.5 million roubles. At the same time, if all manure produced was composted and the bedding was purchased from external sources, the costs would be 27.9 to 35.2 million roubles depending on the bedding material.

Highlights

Ensuring food security is one of the priority areas for global economic development
The field study established the surgical limb diseases to be a serious problem in dairy farming
Under the intensive livestock farming conditions, they are not able to fully provide the optimal environment for keeping the highly producing cows resulting in their lower productivity

Summary

Introduction

Ensuring food security is one of the priority areas for global economic development. Adherence to the principles of sustainable nature management addresses this challenge avoiding the uncontrolled expansion of manufacturing capacities and subsequent waste disposal [1, 2].Agriculture is the only economic sector that can provide the population with high-quality food. Ensuring food security is one of the priority areas for global economic development. Adherence to the principles of sustainable nature management addresses this challenge avoiding the uncontrolled expansion of manufacturing capacities and subsequent waste disposal [1, 2]. Agriculture is the only economic sector that can provide the population with high-quality food. Farming is inextricably linked with the production of the main types of products but a significant amount of waste. The main task of modern agroengineering science is to develop and test new, more efficient and environmentally friendly farming technologies based on smart use of natural resources [3]. The manure management problems are well known to specialists; the rest of the population, practically do not realize them and consider them insignificant. In 2018, Russia produced 2.5 times more animal and poultry manure than the total crop and animal products (Table 1) [4]
