Busol L. Veterinary and Sanitary Expertise of Slaughter Products of Broiler Chickens fed Nanocomposite Powder of Ferromagnetic

The Thesis is devoted to the theoretical and experimental substantiation of the application the nanocomposite powder of ferromagnetic produced by the thermochemical method as a feed supplement in order to increase the productivity of nutritional and biological value of broiler meat. Found that positive effect of nanodrugs is due to its concentration in the units per weight of feed. During its consumption by broiler chickens from 5 to 42 days of age in the doses: 1 mg/kg feed (group 1) the live weight gain increases at 15,1%; 3 mg/kg feed (group 2) - at 10,0%; 10 and 20 mg/kg feed - decreases at 21,7% and 27,7%, respectively compared with the control group of birds. No changes in clinical condition of birds were observed in all groups. The data of hematological and biochemical blood examinations of birds first and second experimental groups enable us to assert that there is no significant difference on the basic parameters compared with control. Veterinary and sanitary expertise of slaughter products of broiler chickens experimental groups showed a positive corrective effect of nano nutriceuticals on nutritive and biological value, technological and cooking properties of meat. The organoleptic characteristics, chemical composition (moisture content, protein, fat), biological value of proteins (amino acid composition), content of macro- and microelements (Fe, Cu, Mn, Zn, Br, Ca and P), chemical and microscopic properties of the breast and thigh muscles of chickens first experimental group (a dose of ferromagnetic is 1mg/kg) exceed pointed out muscle characteristics as the control as the second experimental group (3 mg/kg). While the safety of broiler chickens meat first group is established on the biological objects.
