Morphometric of pig livers under different doses of minerals in feed allowance

Abstract

It is recognized that microelements' compounds in the inorganic form are difficult to absorb by the organism, and increasing their dose to enhance assimilation's level in animals, as a rule, promotes the development of toxicoses. Therefore, the object of this work is to study the influence of dissimilar doses of microelements' complex in organic form (based on an L-Aspartic acid) on the morphometric of the pig liver. The research and production experiment on White Large pigs living in a large pig-breeding complex was made to achieve this goal. To date, the subject has not been studied very much in literature. According to information received, the average distinction between radii from the central vein to the hepatic lobe in 7-month old pigs from different groups is 4-7 mu m. Thus, animals from the control group have 30.3 +/- 0.17 mu m radius, animals which were given to their ration 7.5% of mineral additive from normal range have 32.5 +/- 0.41 mu m (p=0.001) radius, the 2nd control group (10% of mineral additive) have 34.4 +/- 0.29 mu m (p=0.001) radius and the 3rd control group (12.5% of mineral additive) have 50.2 +/- 1.03 mu m (p=0.001) radius. We found that the addition of a 10% chelate complex of microelements (iron, zinc, manganese, copper, and cobalt) increases the activity of metabolic processes in animal organisms from control groups and causes the most expressive beneficial effect of absorbency
