Slaughter condition, safety and quality of slaughter products of turkeys of meat productivity in the use of prebiotic drug Аctigen

Abstract

Ukraine's food security is due to the production of a sufficient number of high-quality, environmentally friendly, high-quality food products of animal origin, including poultry products. The purpose and objectives of the study. To analyze the slaughter condition, safety, and quality of slaughter products of meat turkeys in the direction of productivity when using the prebiotic drug actigen. The object of study was turkeys of the BIG-6 breed. The prebiotic Actigen was added to the essential diet of turkeys in the following doses: from the 1st to the 21st day: 0.4; 0.8 and 1 g/kg of feed; from the 22nd to the 42nd day: 0.4; 0.6 and 0.8 g/kg of feed; from the 42nd to the 120th day: 0.2; 0.4 and 0.7 g/kg of feed. Mixing prebiotics with compound feed was performed with a feed mixer on the farm for compound feed production. The bird had free access to food and water throughout the fattening. According to DSTU 3143:2013, carcasses of broiler turkeys of experimental groups belong to the first category of fattening. The macrostructural characteristics of the organs of broiler turkeys in the experimental groups correspond to the age norm of the bird. Organomacroscopic characteristics of slaughter products of broiler turkeys of all experimental groups do not differ significantly. When determining the organoleptic characteristics of broiler turkey meat after using the prebiotic Actigen, it was established that Volodar LLC, Kyiv region, sells quality products that meet the requirements of the current National Standard. In the study of microbiological and microscopic indicators of broiler turkey meat after the use of the prebiotic Actigen, it was found that the microbiological indicators of MAFANM content in broiler turkey meat of Volodar LLC of the experimental group were 2.12 ± 0.25 × 103 and control groups 2.98 ± 1.07 × 103 according to the norms 1×106 CFU/g – fresh turkey, i.e., met the requirements of the current National Standard. It was found that the broiler turkeys' meat after using the prebiotic Actigen had a higher relative biological value – 100.0 %, compared with the control group of 95.0 % (P < 0.05). The number of Tetrahymena pyriformis cells grown on a nutrient medium with broiler turkey meat after three hours of incubation in the experimental group was 100.0 ± 5.3 – due only to motile cell forms. A similar trend remained after six hours of incubation. Infusoria had the shape of a regular shoe; they are mobile. Therefore, no adverse effect of samples of the meat of turkey broilers of Volodar LLC on the morphophysiological parameters of ciliates of Tetrahymena pyriformis was found, which indicates that the studied meat of the experimental groups is not toxic.
