Abstract

Data are presented on the average daily milk yield of cows during the mass abundance of horseflies, mosquitoes and midges depending on the technology of keeping animals in the Tyumen region. Keeping the cows during this period without grazing on the walking grounds at the farm is one of the methods of preserving their milk productivity. During the period of mass flight of gnats, the milk productivity of cattle grazing in forest pastures is significantly reduced. Loss of milk during this period is 13.68%, while the longer the harmful effects of the vulture, the more significant these losses.

Highlights

Cattle breeding is an important part of the agricultural sector in the Russian Federation
Starting from July 7 the cows were taken to the pasture where they were grazing from 9-10 a.m. and until 4-5 p.m., and starting from July 9 and up to July 23 before driving off to pasture they were treated according to Methodological instructive regulations... (2003), by 0.001% water emulsion of Delcid (4% e.c. deltamethrin, IRC (Innovation and Research Center) "Agrovetzashchita") by the method of medium-volume spraying with the use of universal horizontal wholetube boom sprayer (UHWBS) designed by All-Russian Research Institute of Veterinary Entomology and Arachnology- Branch of Tyumen Scientific Center, SB RAS(Gavrichkin et al, 2018)
Data on the abundance of midges counted in conventional units in the pasture and data on milk productivity of cows during the experimental period in 2018 are presented in Figure 1, according to which swarming of the researched midge types began in the first decade of June

Summary

Introduction

Cattle breeding is an important part of the agricultural sector in the Russian Federation. At the present time many farms in the south of the Tyumen region are choosing zero grazing keeping system in the summer period Such approach is practiced by the farms that keep highly productive imported dairy cows. The goal of this research is to study changes in milk productivity of cows affected by midge attacks with consideration of different types of animal housing To achieve this goal, the following tasks were set: 1) to study the seasonal dynamics of the number of horseflies, mosquitoes and midges in the pastures and farms, and 2) to analyze the changes in milk production of cows before and during the time of the midge season comparing different animal housing systems
