Monitoring of haematological indices of poultry when applying the feed additives on the basis of tripoli
Abstract
In the effective management of poultry, it is necessary to take into account such fundamental components as the technology of growing poultry, the cross used and, most importantly, feeding. Strict observation of technological standards and rules of poultry farming allows getting maximum productivity with minimal labor and money expenditure. The zootechnical service of the poultry farm is obliged to ensure the full-value and balanceness of compound feeds, and if necessary the introduction of various feed additives for preventive purposes that do not reduce the nutritional value of the diet. The veterinary service is designed to support fast -growing poultry and timely respond to the negative processes that occur in their bodies. At present, the introduction of adsorbents of mycotoxins into mixed feeds for prophylactic purposes is a prerequisite for growing a conditioned broiler that meets the standards of the cross. Timely control over the physiological parameters of poultry and prompt correction of pathological changes will ensure high safety of the livestock and increase the gross meat production at industrial complexes. In the conditions of JSC "Poultry farm" Gorodok ", in order to prevent mycotoxicosis, we have introduced into production zeolite-containing feed additives enriched with a prebiotic (" Vami-Lactulose ") and an acidifier ("Kiskad") at a dose of 2.0%. At the end of the technological period of growing in order to monitor the physiological state of the poultry we studied the haematological indices of Ross-308 cross broiler chickens. It has been established that the introduction of zeolite-containing additives contributes to an increase the concentration of haemoglobin in the young poultry blood – by 1.0-3.4 %, bactericidal blood activity (BBA) – by 4.6-5.2 p.p.%, lysozyme activity – by 2.7-2.8 %. In the blood of poultry of all groups the phagocytic index and the phagocytic number have no significant differences.
