“…Форвіт містить комплекс жиророзчинних вітамінів. Вітамін А бере участь в окисно-відновних процесах, необхідний для синтезу глікопротеїнів органічного матриксу кісткової тканини (Parker, Gardiner, Kessell, & Parker, 2017). Вітамін D регулює фосфорно-кальцієвий обмін: стимулює абсорбцію кальцію і фосфору в кишечнику, формування органічного матриксу кісткової тканини та її мінералізацію (Christodoulou, Goula, Ververidis, & Drosos, 2013).…”

Diseases of metabolism, in particular mineral and vitamin, are widespread among animals of various species, and lead to significant economic loses as a result of decrease in productivity.The aim of this study was to determine the effectiveness of veterinary drug «Forvit solution of vitamins A, D, E, F in oil for injection» in the complex treatment of cows with osteodystrophy.The object of the study was 8 black-and-white cows at the age of 4-6 years, with clinical signs of osteodystrophy.The diagnosis was made in a complex base; we took into account anamnestic data, clinical symptoms and laboratory tests of blood serum. Clinical studies of cows were carried out according to the generally accepted methods. After confirming the diagnosis, the animals were prescribed complex treatment. We gave 100 g of Tricalciumphosphate with grain every cow once a day during 25 days and injected intramuscularly 15 ml of «Forvit solution of vitamins A, D, E, F in oil for injection» once every 5 days, a total -5 injections.Inorganic phosphorus -by the spectrophotometric method; calcium (total and ionized) -using the AEK-01 electrolyte analyzer; alkaline phosphatase (ALP) activity according to the Bodansky method; activity of alanine (ALT) and aspartate aminotransferases (AST) -by an optimized enzymatic kinetic method (a set of reagents from Vital Diagnostics SPb); protein -by biuret reaction; cholesterol -by the Endrashik method; urea and creatinine -by the kinetic method were determined in blood serum. Mathematical processing was carried out using the Fisher-Student T-test and the standard "Statistics" package in the EXCEL program.The cause of osteodystrophy in cows was a lack of calcium (30,4 %), phosphorus (30,3%) and vitamin D (86,5 %) in the diet. Clinically, the disease was manifested by unsteadiness of the incisors, resorption of the last caudal vertebrae, and partial lysis of the last pair of ribs. Concentration of calcium and phosphorus in blood serum of cows with osteodystrophy was reduced by 11,5 % and 11,1 %, respectively, and activity of alkaline phosphatase was increased by 47,2% compared with the norm.Concentration of calcium increased by 6,9 %, and activity of alkaline phosphatase decreased by 47,4 % in blood serum of cows after using «Forvit solution of vitamins A, D, E, F in oil for injection» and Tricalciumphosphate.

“…1 In grazing animals, this deficiency is frequently observed during the winter or after grazing drought-affected pastures in which the levels of beta-carotene in the forage are inadequate to meet the nutritional requirements of cattle. 2,3 However, on intensive production systems, where the diet is mostly based on harvested feed, this deficiency can occur at any time without proper vitamin A supplementation. 1 Young animals are the most susceptible within the herd due to their rapid growth, their highest requirements and the lowest reserves of vitamins.…”

Hypovitaminosis A negatively impacts the health of ruminants feeding on low‐fresh forage diets for long periods of time. Although this disease is characterised by different clinical presentations, its congenital form is underreported. Here, we describe an outbreak of vitamin A deficiency that affected 30% of calves born in a dairy heifer herd. At birth, the affected animals showed weakness, ataxia, mydriasis, bluish coloration of the tapetum lacidum and blindness as the main clinical signs. The gross pathological findings at postmortem examination revealed cerebellar herniation, flattened gyri and narrowed sulci of the cerebral cortex in an affected calf. Histopathology showed squamous metaplasia of the efferent ducts in the parotid gland and hyperkeratosis of the ruminal mucosa. In addition, the plasma levels of vitamin A in the heifers and calves were below the reference values. These results confirmed the first reported case of congenital hypovitaminosis A in cattle in Argentina.

“…Whereas oral vitamin E supplementation improved the health of calves at feedlot entrance [ 23 ], parenteral vitamin E (1 mg/kg) and Se (0.1 mg/kg) supplementation improved immunoglobulin G titers against Mannheimia haemolytica in shipping-stressed calves [ 24 ]. Injectable vitamin A is not commonly used because cattle fed fresh grass are not normally deficient, even though rare cases of hypovitaminosis A can occur in extensively grazed beef cattle [ 25 , 26 ]. On the other hand, parenteral vitamin A supplementation has been reported to increase weight gain in calves [ 27 ].…”

We aimed to evaluate the effects of injectable mineral and vitamin supplementation on weaning calves subjected to a low-stress (fence-line) weaning system. Seven-month-old Aberdeen Angus female calves (n = 40, 152 ± 11 kg body weight) from a selenium-deficient area of extensive cattle production on natural grass were randomly assigned to two groups (n = 20 each). One group received subcutaneous supplementation with copper, zinc, selenium, manganese and vitamins A and E (SG), and the other was given sterile saline solution (CG). The animals were supplemented twice, seven days before weaning (day −7) and on the day of weaning (day 0), and they were evaluated 30 (+30) and 60 (+60) days after weaning. Total antioxidant status (TAS), selenium-dependent glutathione peroxidase (GPx) activity, body weight, and average daily gain (ADG) were evaluated. Additionally, antibody titers were assessed prior to and after each immunization with a vaccine containing bovine herpes virus type 1 (BoHV-1). On day +30, body weight (p = 0.03) was higher in SG, whereas TAS (p = 0.02) and GPx (p = 0.0038) activity were lower in CG and remained constant in SG. Antibody titers increased in SG and CG following immunization, being higher in SG on days +30 and +60 (p < 0.05). In conclusion, parenteral supplementation of minerals and vitamins with antioxidant effects in a low-stress weaning system prevented the decrease in TAS and GPx activity, improved antibody response and had positive effects on body weight.

Hypovitaminosis A in extensively grazed beef cattle

Abstract: Plant assays for both β-carotene and crude protein concentrations in dry matter (DM) were less than the recommended dietary requirements for beef cattle (0.30 mg/kg DM and 56 g/kg, respectively).
