The efficiency of use of probiotic feed additive “Propoul PLV” in feeding quails of egg production line is presented in the materials of the scientific and practical publication. The biological effect of the additive is revealed in the rapid growth of positive bifidobacteria, which are able to take away nutrients in the intestine pathogenic organisms, thereby preventing their growth and reproduction. That improves overall health of bird, increases productivity due to better absorption of nutrients feed.
Scientific and industrial research has been conducted in conditions of LLC “Barcom”, Pustomyty district, Lviv region on four groups of young quail, and later adults over 100 birds in each group. Groups were formed by analogues principle by live weight and age. Feed addition was administered in composition of the mixed fodder at the calculation of 4, 6, 8 g/of 100 g mixture by mass to 1st group (control) and 2nd, 3rd, 4th ones (experimental), respectively. Quails were fed three times daily with nutritionally balanced dry chopped concentrated feed. Access to water was free.
It is established that feeding of “Propoul PLV” feed additive with the mixed fodder had a positive influence on the morphoproductive indexes of quail eggs. Mass of an egg white and yolk in the 3rd and 4th groups was higher; the indexes of durability of shell in these groups were the best too. That is important for the estimation of marketability of eggs, and also as amount of standard. An analogical picture was observed and on quality indexes, such as content in yolk of eggs of hepatin, carotenoids, vitamin А. Positive estimation was received by the results of incubation, especially it touches the derivability of quails, the results of that ground to assert about expedience of the use of probiotic feed additive of “Propoul PLV” in feeding quails.
