The electronic feeding system was used in the fattening of young pigs with three, four and five feeding periods per day. Daily feeding time of 15-16 hours, was divided into 3, 4 or 5 equal time periods and daily feed was divided the same way. Therefore, pigs with growing feeding periods received more meals/day but a lower feed ratio/period than those with fewer feeding periods. Together 11 groups each with 14 growing pig were introduced into the trial. Evaluation of performance proved than the number of daily feeding periods did not influence the daily growth rate or, to a small extent, the feed conversion and daily feed intake. But standard deviation of traits dipped significantly with an increase in the number of feeding periods, thus showing a uniformity of production traits. Frequent feeding slightly increased average daily feed intake as well. The analysis of behaviour patterns suggests no differences in daily eating time but significant differences (P<1 and P<0,1) in the speed of eating among the programmed feeding schemes. The greater the number of feedings, the smaller the amount of feed provided in one portion. This obviously raised the eating intensity. Feeding periods regulated in different ways were utilized by the pigs differently: in case of three feeding periods: 97, four periods: 90 and five periods: 84, respectively. As far as behaviour is concerned, growing pigs easily adapted themselves to electronic feeding. Increasing the frequency of feeding was not disadvantageous to performance, moreover it proved favourable from the point of homogenity in production traits and simultaneous finishing of pigs. Therefore, feeding in five daily periods can be recommended for test programmes and production without risk.
