Abstract:
Heteronuclear chelate citrates of the general formula M2I·MII·L2·nH2O (where MI and MII = Mn, Zn, Fe, Co,Cu) have been synthesized. Premixes prepared on their basis were tested in nutrition of layer and broiler poultry. On the basis of experimental data we calculated economic efficacy of egg-laying for layers within 60 days from starting intense egg-laying. Economic efficiency of poultry rearing, for broilers, was calculated from the 7th day after hatching till the 35th day. Computations for broilers were made per 1000 broiler, while for layers – per 20 hens. In both cases four groups were used: I – control, when feed was balanced with the premix used generally at the factory; II group, experimental – with the premix that contained minimal doze of chelate citrates; III group, experimental – with premixes containing normal doze of chelate citrates and the IV group, experimental – with premix containing maximal dose of chelate citrates.On the basis of the experiment results we can conclude that in all (three) experimental groups where the premixes were balanced with the synthesized chelate citrates, the profit, compared to the control group, was higher, while the highest profit was obtained from the group which was given feed with the premix balanced with maximum dose of chelates.We have carried out physical and chemical study of heteronuclear citrates. Solubility of these citrates was investigated in various solvents. It was determined that these citrates are characterized by poor solubility in all solvents, both at room temperature and when heating.To determine the nature of citrate ion deprotonation and linking with metals in the M2I·MII·L2·nH2O type chelate compounds, we made and studied their IR absorption spectra, according to which, the synthesized compounds are the internal type chelate compounds and as it was expected, all three deprotonated carboxylic groups of citrate acid form both ionic and coordination bounds with metal atoms.
