Effect of feeds containing different sources of manganese on certain carcass parameters of quail

Abstract

In the article, results of researches on an establishment of an optimum source of Manganese are resulted. Manganese was additionally added mixed fodder for quails grown for meat. Experimental studies conducted in terms of problem research laboratory of feed additives National University of Life and Environmental Sciences of Ukraine. Independent experiment was conducted with growing Pharaoh Coturnix quails. We conducted a randomized block experiment with 3 treatments, each with 4 replicates of 25 growing birds (1 to 35 d of age). A diet consisting of corn, soybean and sunflower meal, wheat, fish meal, sunflower oil, premix (28% CP, 2.88 kcal of ME/g on 1 to 21d of age, 20.5% CP, 2.97 kcal of ME/g on 22 to 35 d of age) having severally Manganese sulphate, Manganese glycinate and Manganese citrate. Diets and water were offered ad libitum. After 5 weeks of dietary treatments the carcass composition (breast muscles, leg muscles, skin, subcutaneous fat, liver, kidneys, lungs, heart, gizzard) were affected by dietary treatments. Carcass weight and breast muscles was increased (P < 0.05) with organic sources of manganese in the diet. It found little effect (P = 0.053) sources of manganese in the fodder for eviscerated yield. Therefore, Manganese glycinate could be used as a good tool for improving carcass yield of quails.
