Abstract

In the article the results of clinical trials are given in relation to an unconcern and efficiency of new veterinary preparation Bioton, to solution for per oral application, that contains complex biologically active foods of metabolism of mushrooms-endophytes (Cylindrocarpon Magnusianum), medical plants abstracted from a root. For the study of application of veterinary preparation Bioton it was formed 3 groups of turkeys of cross «Big-6», for 25 heads in each. The first group got preparation in a dose a 1 ml/l, the second group got in a dose 2 ml/l of water during 7day in 1, 6, 15, 21 week to fattening, the third group did not get preparation – control. The dynamics of change of body weight was determined by the individual weekly weighing. In times of carrying out the test of rejections in relation to behavior, clinical state of turkeys and diseases did not appear. Preparation Bioton, solution for per oral application, well carried by turkeys, did not cause structural changes in the investigated internals, assisted the improvement of metabolic processes, increase of body and for slaughter exit of carcass weight. Macroscopic of internal organs of turkeys that got preparation Bioton, in a dose 1–2 ml/l of water during 7 days in 1, 6, 15, 21 week of fattening, kept a characteristic anatomic structure. Weight coefficients of thymus, bursa of Fabricius, of testicles were higher in turkeys of the second group. The histological structure of the investigated internal organs specified on their active morphofunctional state in accordance with age of turkeys. The difference of indexes was more expressed in an experience group that got preparation Bioton in a dose 2 ml/l of water. Then, as for the turkeys of control group, we found out the changes of dystrophic-necrotizing character in a liver and atrophy of lymphoid tissue of organs the immune system.

Effect of β-mannanase enzyme supplementation on the morphofunctional state of broiler chickens’ immunocompetent organs

“…Such a discrepancy in the timing of the involution onset may be associated with the active bird vaccination, because this organ is directly responsible for the formation of humoral immunity, and all processes occurring in it are directly related to immunomorphology. In this regard, it is important to assess the morphological and functional state of the organs that are directly responsible for the immunological reactivity of the bird's body (Krasnikov & Keleberda, 1999;Gromov 2010;Zhyla et al, 2016). Such an assessment of the state of immunocompetent organs in a practical aspect is based on the qualitative and quantitative indicators of their tissue, cellular and molecular components, and antibodies, and it is the basis for monitoring the effectiveness and safety of feed additives, immunomodulators, drugs, and vaccines used in veterinary medicine and animal husbandry (Acamovic, 2001;Bäck, 2009;Stehnii, 2013;Romanovych et al, 2019).…”
