The objective of the research was to determine the effect of extruded grain of wheat, barley, rice and naked oats on piglet performance till 56 day of age as well as the parameters of
blood lipid profile. The study involved 400 piglets from 40 hybrid PIC line gilts mated to P-76 boars. The experiment comprised 4 treatment groups, each consisting of 100 weaned piglets
penned in groups of 10 animals. Piglets from group I received diet with extruded wheat, group II – with barley, group III – with rice and group IV – naked oats. The grains were extruded at 14% moisture, temperature profile 120/160,180oC and screw rotation speed 80 rpm. During the study, the production effects on the basis of individual body weight of animals on 4, 28 day of life (weaning) and 56 day as well as the feed intake for each litter were evaluated. The digestibility studies by indicator method were performed on 6 barrows from each group. Blood for analyses was collected twice from 10 piglets from a group on 28 and 56 days of age. According to the research results, extruded rice and oats proved to be more palatable components of diets for piglets than barley or wheat. Their dietary inclusion significantly increased the feed intake and assured a high health status of piglets at the rearing period. Dietary supplement of extruded rice significantly improved piglet performance manifested by higher daily weight gains and better feed conversion ratio. The piglets fed naked oats-based diet showed a significantly lower content of total cholesterol and triacyloglycerols as well as an elevated HDL cholesterol fraction in blood serum as compared to the animals receiving a wheat, barley or rice supplemented diet.
