It was founded a scientifically justified need of workers number and of the stuff provision level of veterinary service in incubatory production hall at the poultry farms with egg manufacture line. There were determined the reasons of incubatory eggs and one day old chicken culling, then a volume and the types of works that are realizing by veterinary workers at the incubatory production hall during from 2012 until 2016 years. We used an analytically-experimental method based on previously established norms of the time spending for making special measures to normalize a work of veterinary stuff in different categories. The production volumes increasing led to raise of veterinary-sanitary actions laboriousness during analyzed period, first of all with special veterinary measures about 11,22–25,51% then with veterinary-sanitary measures about 6,65–10,23%. During analyzed period a number of the veterinary doctors in Private limited company “Chebarkul’skaya ptitsa” were higher than it was required by scientifically justified need on 7,53–17,64% or was lower it on 9,09%, and at the Open joint-stock company “Ptitsefabrika Chelyabinskaya” the number of veterinary doctors was lower than it was required by scientifically justified need on 6,54–12,28% in this period. The number of assistive personnel on the both poultry farms were lower or also higher than it was required by scientifically justified need. The nonconformance with the workers number that required by scientifically justified need is made an influence on the number of newborn chickens, so when it was higher that it necessary for about 2,43% the level of newborn chickens was about 75,17%, and when it was lower for about 5,49% the level of them was 82,8%, that’s why it’s necessary to search any directions to optimize a manning table of veterinary service.
