Abstract
The authors highlight that broiler poultry is considered to be one of the most profitable and promising sectors of agriculture. At the same time, industrial technologies experience unsolved problems, such as death of young poultry in the first weeks of life due to the lack of resistible immune system, which is formed by the end of the third week. In this regard, development and application of immune stimulating specimens is a promising direction for stimulation and maintenance of natural poultry resistance and improve its economic parameters. The specimens used should not affect the quality and products safety. The example of such specimen is ImmuGuard; it was tested in the experimental vivarium conditions at the Department of Veterinary and Sanitary Expertise of Livestock Products And Hygiene of Agricultural Animals at the Institute of Veterinary Medicine And Biotechnology of Omsk State Agrarian University. The researchers arranged three experimental groups from Ross broilers on the basis of similarity. 1st experimental group received the specimen dosed 150; second group of broilers -250 g / t of water during 18 days from the date of hatching, and the 3rd group was arranged as a control one. Growth and weight parameters were determined by individual weighing of poultry every seven days. The quality of broilers’ meat was assessed by means of conventional methods used in veterinary and sanitary assessment of poultry meat. The experience showed a positive effect of the specimen on live weight gain of poultry: the authors observed body weight of broilers aged 42 days from first experimental group was 4.12 higher; broilers from the 2nd group 1.39% in comparison with the control group. The authors highlight a significant increase in the average daily growth: the 1st group showed the growth on 32.21% from the 22nd to the 35th day in respect to the control parameters. Organoleptic, physico-chemical and microbiological parameters of meat of all groups conformed to GOST 31470-2012 and SanPiN 2.3.2.1078-01 standards.

Summary
Ключевые слова: продуктивность, качество мяса, цыплята-бройлеры, иммуностимулятор, иммуностимулирующий препарат. В связи с этим разработка и применение иммуностимулирующих препаратов является перспективным направлением для стимуляции и поддержания естественной резистентности организма птицы и повышения её продуктивно-хозяйственных показателей. Одним из таких препаратов является ImmuGuard, его испытание проводили в экспериментальных условиях вивария на кафедре ветеринарно-санитарной экспертизы продуктов животноводства и гигиены сельскохозяйственных животных Института ветеринарной медицины и биотехнологии ФГБОУ ВО «Омский ГАУ». Из общего поголовья цыплят-бройлеров кросса Ross по принципу аналогов были сформированы три группы: 1-я опытная группа получала препарат в дозировке 150, 2-я – 250 г/т воды в течение 18 суток с момента вылупления, а 3-я группа служила контролем. Росто-весовые показатели определяли индивидуальным взвешиванием птицы каждые семь суток. Качество мяса цыплят-бройлеров оценивали по общепринятым методикам ветеринарно-санитарной оценки мяса птицы.
