Effect of diets with various sources of metonin on quail productivity and carcass quality

M. Sychov, A. Chsherbina


The authors have investigated the effect of different sources of metonin in the diets of quails on their productivity and carcass quality. Experimental studies were carried out with Pharaoh quails in Problematic Research Laboratory of Feed Additives in the National University of Life and Environmental Sciences of Ukraine. The experiment was carried out by method of groups-analogues. Compound feed were fed in dry crumbled form; young birds were fed in a group. The daily amount of compound feed was divided in two parts – morning and evening rations with different sources of metonin (DL- metonin, L-metonin and МНА)).

We have found that compound feed with the L-metonin contributes to live body weight increase by 5.3% or 13 g, average daily growth by 5.9 % or 0.37 g, reduces feed conversion by 2.1%, increases the mass of not gutted carcass, semi gutted carcass and gutted carcass of 12.5 (6.2%), 12.5 (6.2%), and 10.5 g (6.4%); increases the mass of pectoral muscles and muscles of the pelvic limbs by 7.37 and 6.49 g (18.2% and 24.5%) and mass of liver by 0.94 g. Use of diets with MНA and DL-methionine did not significantly effect the productivity and carcass quality, whereas entry to the diet of MNA increased feed conversion by 5.4%. During the study period the safety of livestock which was fed with different sources of metonin ranged from 93 to 96%.

We believed the further research are needed to examine the impact of different sources of metonin on the egg production of egg-laying quails, morphological and chemical composition of eggs and their hatching quality.
