| Popis: | Culling due to poor condition, weight loss, mortalityand, as a result, economic losses due to perosa, accordingto various estimates, 1-5% of the group of birds. Due to thedysfunction of the limbs, the bird can suffer from a numberof diseases. Lack of essential nutrients play an important rolein the development of perosis in poultry. Often in farms dueto cost savings, reduce the cost of feed for broilers, which inturn can lead to metabolic disorders in poultry. Therefore, thediagnosis of these disorders requires new approaches. Modernscience is increasingly inclined to non-invasive diagnosis ofmetabolic pathologies. In human medicine, nails and hair areused to study persistent micronutrient deficiencies. And inveterinary medicine in the study of micronutrient deficienciesas a method of non-invasive diagnosis using animal hair.According to the results of our research, theconcentrations of microelements (Zn, Mn) in the feathers of14, 21 and 28-days-old clinically healthy and feathery broilerchickens were determined. On day 14 of the disease, theconcentration of Zinc and Manganese in broiler chickens withperosis was 65.6 ± 2.73 and 17.4 ± 0.79 μg / g, which wasprobably higher than in clinically healthy birds 46.5 ± 1.57(p |
