Sidorova N. Optimization of the technological process of incubation of eggs of the cross "ISA-WHITE" in walk-in incubators.

Incubative eggs of the adult herd & the day-aged young stock were the object of this investigation. "ISA-White" young stock type was bred for egg production. Technological processes, egg incubation regimes & the methods which promote delivery & ensure viability of the day-aged young stock were regarded as the subject of scientific research. The young stock of the "ISA-White" type was bred for egg production. Genuine technological, zootechnical, morphological & biometrical investigation methods were applied during this research. For the first time in Ukraine the complex evaluation was assessed & the main technological process parametres were developed. Egg incubation quality was estimated. The morphological peculiarities of the embryo development by the "ISA-White" type hen egg incubation were investigated. Pre-incubation egg conservation span & the layer age were taken into account. The eggs were selected for incubation & the improved evaluation method was applied. It was proved that biological controlon the embryo development during incubation & young stock delivery enables to boost chick birth & improve the day-aged chick viability.
