Assessment of the rabbit meat quality and safety when using marbotrim

Abstract

One of the representatives of the third generation fluoroquinolones is marbofloxacin. It was also found that the combined use of trimethoprim and fluoroquinolones has a synergistic effect, which gives good results in the treatment of concomitant infections of the respiratory and gastrointestinal tract [6]. Therefore, the combination of marbofloxacin and trimethoprim in one preparation is very attractive. However, for the introduction of the drug into veterinary practice, a prerequisite is the conduct of preclinical and clinical studies. The research was carried out in the conditions of the vivarium of the Federal State Budgetary Scientific Institution "VNIVIPFiT". The objective of the research was to study the effect of marbotrim on the meat quality. The experiment included 10 rabbits of the Soviet chinchilla breed with a live weight of 2.7-3.0 kg, which were divided into 2 groups. Group 1 (n = 5) was the control and the animals were not administered the drug, the animals of group 2 (n = 5) were injected intramuscularly with the drug marbotrim at a therapeutic dose (0.02 ml/kg) once a day for 3 days according to the instructions for application. A day after the last injection of the drug, a diagnostic slaughter was carried out, followed by a veterinary and sanitary examination of the meat of all animals. It has been found that intramuscular administration of marbotrim at a therapeutic dose does not have a negative effect on the organoleptic and physicochemical indicators of meat quality.
