The pharmacological effects of medicinal plants play a primary role in the mild correction of body weight in humans and animals, reducing the accumulation of fat in their bodies during a state of obesity. Origanum vulgare L. and Scutellaria baicalensis Georgi are widely used as food additives and medicinal plants, but their comprehensive physiologi...

Phytotherapy for the correction of excess body weight is widely used. However, a comprehensive study of herbal preparations on the organism of model animals has been carried out only for a few plant species. Supplementing the diet of rats with closely related sage species (Salvia officinalis L. and S. sclarea L.) against the background of high-fat...

Animal reproduction is one of the main factors limiting the efficiency of livestock production. Its optimal level is possibly achieved when certain conditions are created for animals. As reproduction is a complex reflex process depending on neuroendocrine regulatory mechanisms, the character and strength of stimuli, which, in turn, is due to a numb...

Choosing the optimal time of insemination of she-dogs is one of the urgent problems in the reproduction of dogs, because it causes fertility and can be the cause of artificially acquired infertility or low in fertility. To this end, a number of methods are used in practice, but none of them fully meets the requirements. Therefore, the question of c...

One of the key issues in solving the problem of mastitis is the therapy efficacy. It is important to find such treatments for animals that, along with pronounced antibacterial and other therapeutic properties, have no negative effects. Therefore, the aim of the work was to develop a method for treating goats with mastitis using ozonized materials –...

Comparative morphology forces us to examine organized beings from a multitude of points of view, and must go hand in hand with the study of man. The structure known as anatomy and physiology of the animal's body have been singularly advanced by the discoveries that have been made on animals. Nature has endowed animals with various qualities by thei...
