ADSORPTIVE VITAMIN AND MINERAL FEED ADDITIVES IN MYCOTOXICOSIS PREVENTION IN EGG-LAYING HENS

Abstract

Sometimes fodders of plant or animal origin intended for poultry production do not meet biological safety requirements and are impaired by fungi-producing mycotoxins resulting in huge economic loss. Yet there have been developed and tested feed additives based on the natural minerals and biologically active agents (vitamins, organic acids) - ekobentokorm and adsorptive vitamin and mineral feed additive (AVMFA), which are capable of neutralization of mycotoxins, enrich fodder with highly biologically available minerals and vitamins, thus enhancing digestion, diminishing toxic load, improving fodder safety and productivity, and upgrading fodder composition and ecological sustainability. Morphological, biochemical, and immune status was found improved in the blood of egg-laying hens when fed with compound fodder supplemented with adsorbing additives which enhanced oxidation and reduction processes and protein assimilation in the bird’s organism. These changes resulted in improvement of morphological and biochemical characteristics of eggs thus promoting their biological and nutrition value. To stimulate egg-laying poultry production adsorbing additives ekobentokorm and adsorptive vitamin and mineral feed additive (AVMFA) were introduced in amount of 3.0% of the ration mass. It was found that the most advantageous additive to the compound fodder was adsorptive vitamin and mineral feed additive (AVMFA).
