Cleaning water consumption in milking parlours Сarousel

The article presents an analysis of the actual water consumption for cleaning each zone of various technological operations during the operation of a milking parlor of the "Carousel" type in the conditions of an operating farm. The data obtained can be used at the design stage to calculate the consumption of water resources and the amount of sewage contaminated with manure that requires further storage and disposal.

Introduction. The capacity of livestock complexes on an industrial basis is increasing, both in the whole country and in the Leningrad region. In agricultural organizations of the Leningrad region, the majority of cows are milked in milking parlors. On large dairy farms, it is recommended to use automated rotating milking parlors, the specific area of which, taking into account the holding area and galleries, is on average 8.8% of the animal placement area. These areas should always be kept clean and their washing is carried out, as a rule, after each milking. The purpose of the research is to analyze the actual water consumption for cleaning each zone of various technological operations during the operation of a milking parlor of the "Carousel" type in the conditions of an operating farm.

Object. The object of research is the milking and dairy unit.

Materials and methods. The research was carried out during the operation of a milking parlor with a Carousel-type installation for 50 seats in an operating farm with an average milking herd of 1200 heads and triple milking. Water consumption was recorded every hour in automatic mode in various areas of the milking parlor. The total area requiring cleaning was 925 m².

Results and conclusions. During the monitoring, the average daily water consumption in the milking parlor was 33.5 m³. The main amount of water (45.8%) is spent on cleaning the udders of animals and maintaining cleanliness in the milking parlor during and after milking, 29.3% – on cleaning the pre-milking area and the area of entry and exit of animals to the milking unit, 23.4% – on cleaning the sanitary zone and hoof treatment, 1.5% – on cleaning the maintenance area (inner circle) of the milking machine. The average daily water consumption per unit area when washing the floor and fences in different areas ranges from 5.6 to 49.3 l·/ (m²·day), depending on the washing zone and the degree of its contamination. The data obtained can be used at the design stage to calculate the consumption of water resources and the amount of sewage contaminated with manure that requires further storage and disposal.
