In the process of monogastric animal feeding, including pigs, the special role is played by the quality of coarse grain crops as they compose 70-75% of swine ration structure. Determination of fodder productive effect on fattening swine was realized in the conditions of the Republic of Belarus. The basis of the analyzed fodder was formed by fodder grain of extra fine grade. Research results showed the following: inclusion of extra fine grade barley (Hordeum vulgare) and wheat (Triticum aestivum) (chosen in accordance with the standard of the Republic of Belarus) into all-in-one mixed fodders SK-26 and SK-31 for fattening swine made it possible to obtain higher productive capacity of the experimental animals in comparison with the identical mixed fodders containing barley and wheat of other grades (chosen in accordance with All-Union State Standard 28672-90); in the experimental groups the average daily weight gain in course of the fattening period was on 34 grams higher, and the average selling weight of 1 head - on 4,1 kg than in the control group. Swine which were fed with the presented mixed fodders with grain extra fine grade showed fewer deviations from the rated value of metabolism (blood serum protein and its fractions, calcium, phosphorus, acid capacity) in comparison with the control groups
