Histological Assessment of the Internal Organs of Quails When Adding Amaranth Flour to Their Diet

The main preference is given to the use of natural supplements. Vegetable components are introduced to the poultry diet most often. They can enrich the feed not only with vitamins and micronutrients but also with vegetable protein and essential amino acids. We set the task of studying the effect of amaranth flour on the histological picture of the internal organs of Texas quails. To this end, there were formed 4 groups of one-day quails, 50 heads in each, on the basis of Z.I. Alimchueva’s Peasant Farm Household (PFH) of the Mari El Republic. The first group was as a control and was kept on a normal diet accepted in the household. The Quails of the first experimental group received 5% of amaranth flour, the second and the third ones received 10% and 15%, respectively. After 50 days, the birds were slaughtered and pieces of the liver, myocardium, spleen and bursa fabricii were taken for histological studies. The research has shown that quails received 5 and 10% of amaranth flour to the main diet didn’t develop pathological changes in the internal organs. The third group, where the quails received 15% of amaranth in the diet, developed diffuse fatty degeneration of the parenchymal organs.
