title: [Characteristics of chyme evacuation in sheep as affected by carbamide and other supplementary substances].
abstract: Four experiments with 6 sheep with reentry cannulas of the duodenum were carried out. During the 4th experiment the animals received rations of 60% meadow hay and 20% concentrated blend with 9.4% raw protein. During the 1st, 2nd, and 3rd experiment the sheep received rations with additionally included soya groats, soya groats and carbamide and carbamide and carrots with 17, 18.5 and 17.7% raw protein. The results of the 8 hour experiments showed different quantities of chyme entering the duodenum (from 61 in the 4th experiment till 7,41 in the 3rd one) and differences in the number and capacity of the peristaltic waves for 5 min and for 30 min. The values of pH of the duodenal chyme in the rations, containing carbamide are increased.
