Hepatoprotectors in Highsex Brown” cross parent fl ock hens feeding at their egg production peak

The authors has established that introduction additives with hepatoprotection effect in parent fl ock layers diet has infl uenced positively on metabolism normalization in poultry body through liver morphologic and functional state improvement. Synergistic action of these additives components has been proved to initiate end metabolites content decreasing in plasma such as uric acid, urea, creatinine and bilirubin, and also to vitamin A content increasing. All these show the additives positive action at liver function normalization, A-hypovitaminosis prevention and at egg production level. Egg production intensity and hatching eggs yield have increased by 1.97 and 1.43% in experimental group 1 and by 2.44 and 1.87% in experimental group 2 comparing to control group.
