Testing of the ingredients for the development of a phytobiotic for laying hens

Abstract

At the modern market phytobiotics are widely used. Regulatory legal acts do not restrict the registration status of phytobiotics in any way, there are two registration status - a feed additive and a drug, thus the legal requirements, as well as the development tests for their release are different. When developing a phytobiotic, it is necessary to clearly understand the purpose of its use. According to Rosselkhoznadzor, the VetIS component "Irena" is used to automate the registration process of medicines and feed additives for veterinary use. For a phytobiotic feed additive, the selection of ingredients should be based on such parametres as digestibility and bioavailability. For the choice of the destination mode, the economic benefit should also be as priority. It is rational to use a feed additive at the form of powder or granules, since they are convenient to dose and apply on large poultry complexes. At the same time, the bioavailability of liquid forms for enteral use is higher, but their digestibility on a large poultry population may not be 100 %,and liquid forms are known to have a shorter shelf life, but they are well applicable in a private farms on a small poultry population. Based on the results of the analysis of the regulatory framework for the development of the phytobiotic "Phytogalinarum" for laying hens, the research direction for the development of feed additives for veterinary use was chosen. "FitoGalinarum" is designed to enrich the poultry diet with vitamins, organic acids and dyes (flavonoids) to increase the weight gain of poultry and egg weight. The aim of the study is to compare the indicators of the digestibility and bioavailability of the ingredients of the feed additive "FitoGalinarum" as they are prescribed in liquid and solid enteral forms. According to the results of an experiment conducted in a private poultry farm on laying hens of the Bielefelder breed, a conclusion was made about the higher digestibility and bioavailability of the ingredients-Cinnamon rosehip fruits and Peppermint leaves at the form of powder together with feed, rather than infusion for drinking.
