ISSUE FOCUS 44 FEED & ADDITIVE MAGAZINE June 2022 the metabolism of minerals (potassium, calcium, phosphorus) and acidosis or alkalosis. A poorly working excretory system retains products of metabolism harmful to birds’ health, thus impairing their overall health condition; because of this, water-electrolyte metabolism disorders and reduced excretion of water via the kidneys are observed. The animals develop leg muscle contractions, comatose states, blood thickening and a tendency towards embolism. A dramatic weight loss occurs, and the mortality rate of the birds significantly increases. To help birds survive heatwaves, they should not only be kept under the best possible living conditions, but their water-electrolyte metabolism should also be supported. Environmental changes would streamline the thermoregulation processes, and adequately selected feed additives would prevent water and electrolyte loss. adiVigoSOL® PF IS THE COMPLEX SOLUTION FOR HEATWAVES In the prevention and treatment of water-electrolyte metabolism and acid-base balance disorders, mineral salt solutions combined with plant extracts are important. Such a combination of components is justified since herbal extracts contain easily absorbable bio-elements reducing water and electrolyte losses. An addition of phytocomponents, e.g., flavonoids, anthocyanins, carotenoids, chlorophyll, saccharides, sugar alcohols, amino acids, organic acids and vitamins, support electrolytes’ activity in the regulation of the body’s water metabolism. adiVigoSOL® PF works in multiple ways, like eliminating the consequences of malabsorption syndrome, leading to diarrhea and dehydration. Tannins in the treatment reduce intestinal oedema by constricting the dilated gastrointestinal blood vessels, thus preventing water loss and the development of inflammatory conditions. Vitamin C, flavonoids and tannins all promote cell membrane integration while also inhibiting inflammation and pain mediators, reducing the effects of stress in the birds. Flavonoids, anthocyanins and phenolic acids effectively prevent embolism and thrombus formation and improve blood circulation. By using adiVigoSOL® PF, you can contraindicate the frequently recommended administration of salicylates during heatwaves to reduce the risk of infarctions or embolism. On the one hand, salicylates eliminate blood thickening but on the other, they can cause tissue bleeding, and in the case of developing acidosis, they can intensify it. They also cause mucosal hyperaemia (blood accumulation under mucous membranes), which leads to the entry of pathogenic micro-organisms and infections during or shortly after heatwaves. adiVigoSOL® PF also contains similar ingredients to Ringer’s solution. It’s rich in components preventing the development of acidosis and hypertonic dehydration (a higher loss of water than electrolytes) and isotonic dehydration (simultaneous loss of water and electrolytes). It also retains water in blood and lymph and prevents chloride loss. The liquorice extract in adiVigoSOL® PF has similar properties and simultaneously protects the DURING HEATWAVES, THE FOLLOWING SHOULD BE KEPT IN MIND: • An air velocity of 8m3/h/kg per live weight of birds should be maintained; • Access to drinking water (stocking density); • There should be twice the amount of cold water (10-12ºC) available than usual; • If possible, the feed availability hours should be changed to morning and evening; • A higher concentration of feed components with a reduction of raw protein concentration (tobe supplemented with synthetic amino acids); • Adequate levels of minerals (E, D, K, A) and vitamins (B) in feed and water; To exchange a part of the energy supply to carbohydrates for energy from fats (reduced heat production by the organism).
