Influence of feeding the nano-structured form of b-carotene to egg-laying quails at the beginning of laying on productivity indicators

Purpose: checking the assimilation of beta-carotene from a nanostructured globe and influence 10% on productivity organoleptic qualities products. Materials methods. Experience was conducted basis Russian Pularka farm "Russian Pularia" Leningrad Region. 2 groups quail meat - egg direction Estonian breed were formed for 10 goals at age 50 days beginning production. All quails contained in same conditions, all parameters microclimate premises, front feeding post corresponded to recommended standards. Egg evaluated accordance with GOST 27583- 88 context groups: mass number eggs determined by loafer; Color yolk Rosh scale; The content vitamin A yolk. experience included three stages: 1 st day-the implementation landing quails; 2-10 adaptation bird new conditions content; 11-20 directly accounting period experience. Feeding control group carried out standard compound feed PC 1-1 production Gatchinsk factory. For an experimental group, mixture prepared addition 10%. (control) food rate 30 g/head. Group (experimental)-PC g/head + 36 mg (at 150 mg/kg poultry mass). weight each fixed daily journal. Eggs stored separately. Results. IResults. fodder forms are not economically impractical, especially industrial breeding bird. In our work, we studied introduction polymer complex form B-carotene into complex, which is unique. It emulsions fat -soluble vitamins, can be considered as nano. studies have shown that intensity color yolks significantly higher than this indicator shows bio-converters β-carotene egg. At time, masses higher, but excess small.
