Biochemical peculiarities of blood serum of mares of the Yakut breed when using a grain from beer in the diet

The purpose of the research was studying the influence of a beer pellet on metabolic processes of mares' organisms. The results of the research of biochemical composition of blood serum of mares of the Yakut breed of horses during their winter feeding with using in a diet of a beer pellet - a byproduct of production of light beer grades are presented. For carrying out scientific and economic experiment two groups of mares of the Yakut breed (control and experimental groups) up to 10 heads in each were created. The animals of 4-5 years old, were characterized by identical fatness and liveweight (400±10), were clinically healthy, a month before the start of the experiment the horses were dewormed. The blood from mares was taken 2 times by the standard technique - before the beginning and at the end of the experiment. The experiment began at the end of February and lasted for 45 days. During feeding the mares were held in special pens. The main diet consisted of 2 kg of hay with winter pasture...
