hormone of the hypothalamus, which consists of pentapeptydnoho cycle and side chain residues of three amino acids that accumulate in the posterior pituitary. It increases the permeability of sodium myofibrils uterus, stimulating its contraction. Threshold oxytocin induced contractions of the uterus decreases during pregnancy, high estrogen or if the animal has already begun delivery.Oxytocin is decomposed in the gastrointestinal tract, so it should be administered parenterally. After intramuscular administration of the drug effect observed after 3-5 minutes.
Ivermectin has a pronounced antiparasitic effect on the larval and sexually mature stages of the nematodes of the gastrointestinal tract and lungs, larvae of subcutaneous, nasopharyngeal, gastric gadfly, lice, bloodsuckers, and sarcoptoid mites. The drug enhances the production of a neurotransmitter inhibition - gamma-aminobutyric acid, which leads to impaired transmission of nerve impulses, paralysis, and death of the parasite.
Due to the micellar dosage form of ivermectin and the addition of vitamin E, the drug is rapidly absorbed from the injection site, distributed in the organs and tissues of the animal, providing a parasiticidal effect for 10 to 14 days. In recommended doses, it does not have a sensitizing, embryotoxic, teratogenic and mutagenic effect. It is excreted mainly with urine and bile, in lactating animals with milk. In the external environment, the drug is rapidly destroyed. Toxic to fish and bees.
Vitamin A plays a key role in maintaining healthy eyes, skin, and mucous membranes in the respiratory, digestive, and reproductive tracts. It is also important for the proper functioning of the kidneys and the normal development of bones, teeth, and nervous tissue. Vitamin A comes from carotene, which is found in green and yellow plants.
Vitamin D is crucial for bone and digestive health. The animal body is endowed with a natural mechanism for the formation of vitamin D when exposed to sunlight.
Green leafy foods and whole grains are sources of vitamin E.
“While the animal’s need for vitamin E is critical, the specific physiological function of vitamin E is still unclear,” says Eric Bailey, a cattle feeding specialist at the University of Missouri. “Its main role may be as a chemical antioxidant to reduce the breakdown of other vitamins and essential fatty acids both in the digestive tract and after they are absorbed.”
In fact, vitamin E has been shown to be effective in treating white muscle disease in calves.
Fortunately, possible problems associated with a lack of one or more of these three vitamins do not occur as often as you might think.
