Experimental evaluation of the acute toxicity and irritant effect of “BTF plus” – a veterinary medicinal product for the normalization of metabolic processes in animals and poultry

Abstract

Laboratory studies were conducted to determine the acute toxicity of the veterinary drug “BTF plus” on white rats and white mice. The preparation “BTF plus” is a complex vitamin and mineral preparation, which is used to normalize and correct metabolic processes in poultry and animals. The drug is used for various types of animals and poultry as a stimulating, tonic and general strengthening agent for: obstetric pathologies (difficult births, postpartum complications, paresis, eclampsia, sexual cycle disorders); metabolic disorders caused by irrational feeding, malnutrition, asthenic syndrome, etc.; anemia with helminthiasis; secondary anemias, as an additional means in the treatment of magnesium and calcium deficiency; to increase muscle activity, with significant loads, overstrain and exhaustion in animals; to increase the body’s resistance to various pathogens; to stimulate growth, development and live weight gain in young animals; as an additional means in the treatment of diseases caused by various factors (infectious and non-infectious origin). Based on the results of determining the parameters of the acute toxicity of the drug “BTF plus” in the case of a single intragastric administration to white female rats, it was not possible to calculate the LD50, since the death of laboratory animals was not detected within 14 days after administration. At the same time, the maximum injected dose (based on the absolute weight of the drug) was 40000.0 mg/kg of body weight, which allows the drug to be classified as VI class of toxicity – the substances are relatively harmless (LD50 > 15000.0 mg/kg of body weight), and according to the degree of danger to IV class – low-hazardous substances (LD50 > 5000.0 mg/kg of body weight). Based on the results of determining the parameters of the acute toxicity of the drug “BTF plus” in the case of a single subcutaneous injection to white female rats and male mice, it was not possible to calculate the LD50, since the death of laboratory animals was not detected within 14 days after administration. At the same time, the maximum injected dose (based on the absolute weight of the drug) was 20000,0 and 40000.0 mg/kg of body weight for both species of animals, respectively, which allows it to be classified as VI class – relatively harmless substances (LD50Subcut > 4500 mg/kg of body weight). Further studies will be the next stage of pre-registration tests aimed at studying the embryotoxic effect of “BTF plus”, which is mandatory material of the “Safety and residue studies” section of the dossier for this drug.

Research on the embryotoxic effect and carcinogenicity of the drug “BTF plus” – a means for normalizing metabolic processes in animals and poul-try

“…Therefore, today, the development of tonic, stimulating, and strengthening agents, which are an integral part of systemic therapy and possess significant efficiency and envi-ronmental safety, has remained relevant (Sachuk, 2019;Sachuk et al, 2019Sachuk et al, , 2023. Thus, "DAVIE" LLC was offered a new drug -"BTF plus".…”
