The influence of “Therapeutic and preventive immunoglobulin” immunostimulant on the veterinary and sanitary assessment of meat and the histological features of the parenchymatous organs of cattle

Abstract

Abstract The aim of the research is to study the effect of “Therapeutic and preventive immunoglobulin” immunostimulant on the veterinary and sanitary assessment of meat and the histological features of the parenchymatous organs of cattle. The study showed that pH of the meat in the experimental group was 5.32±0.03, in the control group – 5.43±0.02, the level of amine ammonia nitrogen – 1.19±0.02 and 1.21±0.01 mg in the experimental and control groups, respectively. The peroxidase reaction was positive both in the experimental and control groups, the reaction with copper sulfate was negative. The copper content was 34% more in the experimental group than in the control group (1.80±0.03 mg/kg). The concentration of zinc was 38.5±1.32 and 23.1±0.98 mg/kg in the experimental and control groups, respectively. The levels of iron were similar in the experimental and control groups. The cobalt content in the meat of calves in the experimental group was 24.6% higher than in the control group. The concentration of selenium and magnesium in the meat of calves in the experimental group was higher than in the control group. Such heavy metals as lead, cadmium, mercury and arsenic were not found in the meat of the calves in the experimental and control groups. According to the results of the histological study, the drug does not cause pathological changes in the structure of the liver, kidneys, myocardium, lymph nodes and spleen.
