Вплив інтровіту на природну резистентність та енергію росту телят

Abstract

Викладено дослідження впливу інтровіту на показники природної резистентності і енергію росту телят. Встановлено вірогідне підвищення гуморальних, клітинних показників неспецифічного захисту організму а також живої маси та середньодобових приростів у телят, яким вводили інтровіт.

The purpose of our research was to study the formation of heterospecific resistance of organism, growth energy of calves at the use of immunostimulant of new generation – introvit which consists of vitamins A, D3, Е, B1, B2, B6, B12, В3, В5, Н; amino acids: methionine and lysine. During the study of humoral factors bactericidal activity of blood serum in a test group after introduction of introvit increased from 59,9±4,9% to 68,3±1,1 %, and lysozyme activity - from 8,1±0,2% to 12,8±0,4% (Р < 0,01). The growth of indexes of phagocytic activity of neutrophils was also marked - from 43,9±0,8% to 52,7±0,5% (Р < 0,01). Introduction of introvit also influenced the productive indexes. Thus, at birth, living mass of humoral calves of test and control groups was practically identical. Henceforth, calves which got introvit grew more intensively. Therefore, growth energy of test group was higher than of control group: by 20,4 % on 30th - day, by 8,9 % - on 60th - day and by 16,4 % -on 90th - day. Reliable increase of humoral, cellular indexes of heterospecific protection of organism and also living mass and average daily growth in calves which got introvit were determined.
