Abstract
Test was conducted in 1960-61 with the purpose to study the effect of feedine different rations to pregnant ewes during late gestation on their production (body weight, fleece and milk yield and birth and weaning weigght of lambs). Fourteen pregnant five - year - old „pramenka“ ewes were devided into two uniform groups, about 60 days before lambing time. Both control and treated group dropped two pairs of twins and five singles (six female and three male). The first group of ewes was fed 1,5 kgs meadow hay and 0,25 kg concentrate dailv per ewe.The concentration mixture consisted of maize 40 %, wheat bran 30% , ground oats 15%, sunflower oil meal cake 11% , mineral mixture (koštan) 3% an salt 1%. The second group (control ewes) was fed 2 kilos meadow hay daily per ewe only. According to Popov, both rations had the same nutritive value (1,1 nutritional units and 75-82 grammes digastible proteine). After lambing time treated and control ewes wene fed as one flock. According to the results of this experiment cuold be concluded that pregnant ewes can be fed good quality meadow hay as the only ration. No significant difference in average body weight, wool and milk yield of ewes, and birth and weaning weight of lambs was found.
