The productivity and quality of production of quails for influence dietary supplements
A complete and balanced feeding of quail is one of the factors that affect the defense mechanisms in the body and, in fact, the productivity and product quality. Therefore, it is important to development of ways to increase the transformation of nutrients and bioactive compounds in food products based on the poultry industry finding out ontogenetic regularities of growth and development of quail. At the articles provides the results of checking of the effectiveness of the complex feed additive «Bilo-Activ» in feeding quail and supplement to their food ration Copper, Zinc and Manganese in order to increase of productivity and improve the quality of the resulting product. In previous studies it was found that during of the ontogenetic the growth and development of quails infringement taking place of metabolic processes and are characterized by a decrease in protein synthesis in tissues, the activity of hydrolytic enzymes in the digestive tract and Zinc, Copper and Manganese in the muscles, skin and feathers. However, the peak of the biggest changes accounted for of quail 21-, 42-, 72-day age. Therefore, the experiment was conducted on three groups (two experimental and control) of quails breed of «Pharaoh». Of the poultry has been free access to feed and water, in accordance to the existing technological requirements. All poultry received complete feed, balanced in nutrients and bioactive substances. Quails first experimental group received the complex fodder additive «Bilo-Activ» in an amount of 0.15% to the basic diet and the second research groups – addition to diet a mineral supplement with minerals Zinc, Copper and Manganese. It was established by the end of the experiment in quail, which were added to the feed «Bilo-Activ» with surcharge Zn, Cu, Mn, was the highest body weight (was 251.95 grams, an increase of 12.67% compared to control) and egg production (the highest at 7.37% compared to control). It was shown that under the influence of the complex and mineral supplements increases biological and nutritional value of eggs and meat by increasing the number of important minerals.
