Productive qualities of laying hens against the background of body immunoprophylaxis

In the present study, the feasibility of using the complex probiotic preparation Immunoflor in egg production technology to increase the egg production and quality of the eggs of laying hens of the Decalb White cross hens was carried out. Against the background of the use of this drug, it was found that the average daily egg production in the 1st and 2nd experimental groups exceeded the control layers: by 150 days - by 9.66 and 8.48 %, by 180 days - 8.8 and 5.04 %, by 210 days - 8.16 and 6.44 %, on 240 days -11.68 and 3.8 %, 270 days - 7.72 and 4.84 %, on 300 days - 8.34 and 5.86 %. In addition, the average daily egg mass of 1 and 2 experimental groups was higher than in the control, by 4.04 and 3.1 g or 7.38 and 5.77 %; on the 7th day of storage - by 4.06 and 3.1 g or 7.53 and 5.87 %; on the 14th day - by 4.32 and 3.16 g or 8.18 and 6.12 %, respectively. It was found that on the 7th day of storage, the loss in egg mass in the 1st and 2nd experimental groups were 1.50 and 1.56 %, which is lower than in the control (1.66 %). On the 14th day of storage, the loss in egg mass in experimental groups 1 and 2 was 1.95 and 2.36 %, which also turned out to be lower than in the control (2.63 %).
