Study of physiological activity of microelements- and glutamine acid-containing chelate citrates

摘要

Premixes prepared on the base of microelements and glutamine acid-containing chelate citrates and their composites with natural zeolite, clinoptilolite were tested in mixed feed for rabbits. Optimal composition and quantity of chelate microelements were determined on the base of test and major experiments. To study more thoroughly the results of the experiments the control slaughter was performed in 120 day old rabbits. Live mass indices of the first experimental group animals (when mixed feed was balanced with the premix that contained microelements and the composites of glutamine acid chelate citrates and clinoptilolite) slaughtered at 120 day age exceeded those of the 2nd (when mixed feed was balanced with premix that contained microelements and glutamine acid chelate citrates) and those of the control group (which was given the fodder used commonly at the farm) by 0.15 and 0.45?kg, respectively. As to the index of slaughter weight, here again the animals of the first experimental group occupied the leading position and this index equaled to 55,07%, that of the second group was- 54.54%, while that of the control group - 51,7%. Meat coefficient index in the first experimental group was 3,11, in the second group - 2,95, and in the control one - 2,89. Study of masses of inner bodies of rabbits after their slaughter showed that the animals of the first experimental group were distinguished by the best indices while the animals of the control group showed the least indices. For more profound study of meat productivity we investigated chemical characteristics of rabbit meat: water, fat, protein and ash. It was proved that here again the animals of the first experimental group show comparative advantage. Fat index in the meat of animals of the first experimental group equaled to 9,2% and exceeded the fat indices of the meat of animals of the second and control groups by 1,4 and 2,1%, while the fat index of animals of the second experimental group exceeded that of the control group by 0,7%. Water and protein were fixed in greater quantity in the meat of the control group animals which is logical. Study of skin-and-fur quality, after slaughter of rabbits, proved that here, again comparative advantage was shown by the animals of the first experimental group. Indices of the animals of the second experimental group exceed those of the control one, but legged behind those of the first group.
