Sažetak

The aim of this study was to indicate the nutritional status of growing Tsigay breed lambs (n = 20) in organic breeding. Lambs suckled and had a mixture of grains and alfalfa hay ad libitum, while during fattening were fed mixture and alfalfa hay ad libitum. Lambs were weighed at birth as well as at the average age of 40 days and in the fattening period (70 days), when and other exterior characteristics and blood were taken. Production traits and exterior characteristics of lambs in suckling and fattening period were satisfactory, although according to genetic potential production results of lambs could have been better, especially in the suckling period. Concentration of Fe in the blood of lambs was at the lower limit of reference values, indicating a lack of this element in feed. Rich meal energy is indicates by the concentration of glucose in the blood that was at the upper limit reference values and concentrations of thyroid hormones and triglycerides in the blood of lambs. Concentration of urea and albumin in the blood of fattening lambs indicated on inadequate supply of protein. Enzyme activity and haematological parameters in blood of lambs did not show significant changes compared with the reference values of weaned lambs. All this points to the problems in feeding sheep in organic breeding because the growth of suckled lambs largely dependents on nutrition sheep-mothers. Therefore, determining the blood metabolic profile and body condition scores, with the establishment of production traits, can be taken as reliable indicators in monitoring the nutritional status of lambs in organic breeding.
