The research material consisted of 87 Suffolk ewes divided into control (1) and experimental (2) groups. Both groups were fed farm feeds according to DLG standards.Animals from the experimental group were given an addition of the nutritional pectin concentrate with an immunological effect (KO) produced on the basis of apple pectins. Dams were given approx. 10 g per animal per day of the preparation mixed with concentrate every 7 days during tupping, every 3 days during pregnancy and everyday during the rearing of lambs. Lambs were reared with their dams. From 14 days of age their diet was supplemented with the evaluated preparation mixed with oat meal and then with concentrate at the amount of 10% of a given feed. Reproduction results of 87 ewes including fertility, prolificacy, rearing of lambs and reproduction indices were evaluated. Based on the body weight of lambs at 2 days after birth and at the age of 1 month, 56 and 90 days, as well as on the daily body weight gains in the individual examined periods, the evaluation of the growth of the offspring being reared was performed. In the statistical analysis of the obtained results, Student’s t-test (addition of preparation) was applied. It was found that dams from both groups were characterised by similar and very low fertility (54.7–58.2%). The applied pectin preparation significantly (P≤0.01) affected the value of the prolificacy index of the examined sheep. In this respect, the ewes from experimental group were over 32 per cent better than the ewes from the control group. Similar tendency was observed for the rearing of lambs and the values of reproduction indices. The offspring of both groups of dams weighed at 2 days after birth had similar body weight. From 1 month of age a significant advantage of lambs from experimental group was observed both in respect of body weight and daily body weight gains.At the last weighing at 90 days of age, lambs given the KO preparation were significantly heavier (P≤0.01) than their age mates from group 1. In the whole experiment, lambs from group 2 were characterised by approx. 26 g higher body weight gains (P≤0.05) compared to lambs from group 1 and the values of the growth rate indices for animals in both groups were similar.
