Sažetak
The aim of the research was to determine the possibility of replacing soybeans as the most common source of protein in the diets with pumpkin seed cake by-products in oil production and to determine the influence on lamb production and their haematological indicators. The study was conducted on 20 Merinolandschaf lambs at the age of 70 days. Lambs were evenly divided by gender and then allotted to two treatment groups: control with the soybean as a source of protein in a fodder mixture and experimental in which the soybean was replaced with 7% of pumpkin seed cake. Lambs had hay and water ad libitim. Body weight and lamb blood samples were taken on day 0, 15, and 30 of the study. In addition, the average daily gain, conversion, and lambs indexes of physical development were calculated. Analysis of the obtained results at the end of the study did not reveal significant (P>0.05) differences in body weight (29.80 : 28.98 kg), body measurements and indexes of physical development of lambs fed soybean and pumpkin seed cake. In addition, there was no significant (P>0.05) differences in average daily gain between the control and experi-mental group of lambs (232 : 230 g). Conversion in the control group of lambs was 3.54 kg/kg and in the experimental group of lambs 3.62 kg/kg. By consummation of pumpkin seed cake as a source of protein in rations of lambs there was no change in production - haematological parameters of lambs. By using pumpkin seed cake in rations of lambs it is possible to substitute soybean of suspected genetic origin and health safety. With regard to ecological pumpkin production, it is possible to emphasize the nutritional and dietary quality of lamb’s meat, and the organic producers might have the adequate protein source available.
