Feeding behaviour is a permanent subject of research in connection with the more comprehensive study of the mechanisms controlling forage consumption and digestibility and appropriate productive characteristics of animals. The objective of this study was to compare some characteristics of feeding behaviour of early weaned lambs, the one group of which at live weight of 9,5 кg tо 22 кg was fed with rations based on lucerne hay and dried pelleted distillers grain, maize grain and soybean oil meal and the other group was given wheat straw instead of hay. It was found that lambs ate 52 to 75 times per a 24-hour period provided that the time of eating of more than 1 minute is taken as one feeding. The total time spent by lambs for eating and rumination was 41 tо 50% of the whole time of the 24-hour period. There was a higher rate of forage intake expressed by g DM intake/min in lambs fed with lucerne hay, as compared to those fed with the ration based on straw. The time of intake and rumination of 1 kg DM of the ration based on straw was 23% longer than that in feeding with the ration based on lucerne hay.
