Effectiveness of mineral supplementing productivity and hematological parameters of meat quails

Keywords: quails, feed supplement, productivity, slaughter, muscle, blood


The mineral elements contained in poultry feed do not fully meet their needs. Therefore, the elements that are lacking in the diet are introduced into the feed or feed mixtures to ensure mineral integrity. The aim of the experiment was to research the cobalt chelate complex effect on live weight, weight gain, slaughter quality and hematological parameters of Pharaoh quails.Scientific studies of the cobalt chelate complex effect on quail productivity were conducted on a research farm of Vinnytsia National Agrarian University. Two 20-bird groups were formed on the principle of analogues. The experiment lasted for 42 days, i.e., equalization period lasted for five days, and the main period lasted for 37 days.Control slaughter was performed at the end of the experiment, four heads from each group were slaughtered to determine the main indicators of slaughter and blood. The quails additionally fed by the cobalt chelate complex outnumbered their control counterparts in life weight, i.e., females by 8.5 % (P 0.001) and males by 7.9 % (P 0.001).Feeding supplements increases the absolute increase by 8.5 % (P 0.001) in female quails and by 8.1 % (P 0.001) in male quails of group II than in the control group.Due to the action of the cobalt chelate complex in group ІІ, feed consumption per 1 kg of growth is reduced in females by 6.62 % and males by 6.12 % relative to control counterparts.In group ІІ, the pre-slaughter live weight of quails increased by 7.7 % (P 0.05), the gutted carcass increased by 8.1 % (P 0.05) and the gizzard weight increased by 7.8 % (P 0.05) than the control indicator.The cobalt chelate complexapplication increases the weight of the breast by 12.1 % (P 0.01) and thigh by 14.3 % (P 0.05) in group II relative to control analogues. In group II quails of the amount of hemoglobin increases by 7.2 % (P 0.05) under the action of the researched supplement in comparison with the control sample.
