The period of replacement growing of broiler parental herd is conditionally divided into four phases: 0–8, 8–12, 12–16, and 16–20 weeks. Use of special feeding programs during this period allows receiving pullets with specified live weight, high productivity, as well as achieving uniformity of herd.

Poultry of numerous breeds and populations, kept in the collection of the All-Russia Research Institute of Genetics and Livestock Breeding (VNIIGRZh), are carriers of autosexing genes, bright colouring of plumage, skin and egg-shell pigmentation, decorative and productive qualities. For this reason, hens and cocks are used for creation of Russian coloured crosses that are demanded in farmer (peasant) and personal part-time farms.
Keywords: poultry production, food security, meat-egg and egg-meat crosses, breeding material, selection, autosexing population, gene fund, genetic variety, hens, productivity.
Sea-buckthorn berries and bioginseng oilseed meals used in chicken diets as feed additive either separately or combined, allow correcting hematological indicators of layer blood, and also stimulate resistance of their bodies and promote improvement of immunological indicators.

Modern egg poultry crosses show excellent results, however, if appropriate keeping is provided. Nevertheless, geneticists continue improving crosses, because increase of egg production profitability requires layers with increasing productivity.

Poultry red mite (Dermanyssus gallinae) and northern fowl mite (Ornithonyssus sylvarum) are most common external parasites of poultry. They are carriers of very dangerous diseases. The key mite control measures are treatment of premises and poultry with acaricides and insecticides as well as surveillance of mite distribution at farms.
