Proizvodno-hematološki učinci primjene pira (Triticum aestivum spp. spelta L.) u tovu janjadi

The aim of the research is to determine the possibility of using spelt in lamb diets and to determine its effect on productivity and haematological status of lambs. The research was conducted on an organic family farm, which farms Merinolandschaf breed sheep. The research included 21 lambs in the average age of 95 days. Lambs were evenly divided by sex into three groups: I.- control group ; II. - group with 10 % of dehulled spelt and III. - group with 20 % of dehulled spelt. Lambs had hay and water available ad libitum. Body weights, measures and blood samples of lambs were taken on the 0th, 15th and 30th day of research. In addition, the average daily gain, feed conversion, and lambs indexes of physical development were calculated. Analysis of the obtained results at the end of the research did not reveal significant (P>0.05) differences in body weight (35. 89 : 34.92 : 34.99 kg), body measures, and indexes of physical development of lambs depending on group. In addition, there were no significant (P>0.05) differences in average daily gain between control and experimental groups of lambs (237.71 : 209.71 : 207.14 g). Average feed conversion in control group of lambs was 4.40 kg/kg, in II. -group 4.97 kg/kg, and in III. group was 4.99 kg/kg. By consuming spelt as organic grain and his substitute for common cereals (barley and oat) in rations of lambs, there was no change in production - haematological parameters of lambs. With regard to the higher resistance to environmental factors, spelt can be cultivated in harsh ecological conditions, on organic way, which even more emphasize quality of lamb’s meat.
