The effect of fish skin mucus on hemostasis indicators of some animal species in vitro in comparison with collagen
Modern pharmacology is actively searching for new sources of natural peptides and developing new methods of their synthesis for further introduction of protein preparations into production, so it is necessary to identify the natural sources of biologically active peptides, such as fish skin mucus. In order to assess the effect of fish skin mucus on animal hemostasis indicators in vitro in comparison with collagen, the hemostatic activity of skin mucus of carp (Cyprinus carpio carpio Linnaeus, 1758) and African clarias catfish (Clarias gariepinus Burchell, 1822) on the blood of cows and dogs was studied. It was found that the most active in the hemostatic relation was the mucus of the African Clary catfish. Hematological and statistical methods of research were used in this work.

Thromboelastographic Assessment of Coagulation Potential of Blood in Horses
The work reviews the possibility of using thromboelastogram to assess the coagulation potential in horses. The experiment engaged ten clinically healthy mares aged from one to five years and five newborn foals up to ten days of Russian trotting breed. The thromboelastogram was recorded in citrated blood by means of a two-channel computerized Coagulation Analyzer (TEG® 5000 - Hemoscope, USA) and applied diagnostic program. Such parameters as R (min), K (min), Ang (°), MA (mm) were taken into consideration; no significant difference was found in parameters between mares and foals. R (min) and K (min) were higher in horses (13.55 ± 2.11 min and 4.6 ± 0.91 min, respectively) than in foals (12.77 ± 0.41 min and 3, 65 ± 0.34 min, respectively). Ang (°) was lower in horses compared to foals (46.41 ± 5.89 ° and 52.14 ± 3.58 °, respectively). MA (mm) was at the same level in animals of both groups and amounted to 57.28 ± 3.04 mm in horses and 57.77 ± 2.59 mm in foals. The work presents reference coagulation intervals in adult horses and foals, but when interpreting of individual results, the effect of hematocrit, platelet count and fibrinogen concentration must be taken into account.
Changes in Milk Productivity Using the Feed Concentrate “Urga” in the Diet of Highly Productive Cows
The results of research in milk productivity of lactating cows using the feed concentrate “Urga”, products of the EM series (LLC “EM-cooperation”) were analyzed. The received the feed concentrate “Urga” animals had higher monthly milk yield, the amount of milk produced in terms of base fat and protein, higher level of realization of productive capacity, which pointes out the feasibility in developing a feeding program and increasing the efficiency of milk production.
