Information × Registration Number 0209U005997, 0106U004244 , R & D reports Title To prove and develop the methods of increasing of genetic potential realization of egg crosses hens. popup.stage_title Head Boroday Vitaliy, Registration Date 24-06-2009 Organization National agricultural university of Ukraine popup.description2 Object of researches: laying hens of industrial herd, hens chickens of paternal herd, incubation eggs. Purpose of work - to reserch the level of the productivity of egg hens of modern crosses at the different methods of maintenance and feeding; to develop the methods of increase of realization of their genetic potential. Methods of researches - experimental, statistical. As a result of the conducted researches substantial influence of feeding, terms of maintenance, different technological equipment on the level of realization genetic potentials of the productivity of the specialized egg crosses hens on the indexes of the egg productivity, safety of bird and expenses of electric energy at the egg production are set. The use of methods of mathematical modelling (with the use of models of Mak-Millan, Mak-Nelly, T.Bridges, F.Richards) and parameters of intensity of increase of laying productivity for the estimation of level of laying productivity and description of curves of laying productivity allows to set the level of realization of genetic potential on the egg productivity.Poultry.
