Sažetak
Biological investigations were carried out on 20 Tsigai sheep divided by age (10 from 3 and 10 sheep young than 1 year). The sheep fed with of 300 g a feed mixture and meadow hay (ad libitum). In this investigation determined body weights, exterior traits and blood biochemical concentration (glucose, urea, total proteins, albumin and cholesterol) and thyroid hormones (T3, T4) of sheep. The average body weight of adult sheep was statistically much higher (P<0.01) comparing to the sheep younger than 1 year (76.60 and 46.15 kg) as well as exterior traits (body measures: body length, chest circumference, chest width and chest depth ; index of anamorphosis, body proportion and body condition score) with comparing to the sheep younger than 1 year. The concentrations of total proteins and albumin within the blood of the adult sheep (74.98 and 30.31 g/L) have been statistically much higher (P<0.01) comparing to the sheep younger than 1 year (68.73 and 27.19 g/L). Analyses of thyroid hormones in Tsigai showed statistically lower (P<0.05) levels of T3 in ewes under 1 year in comparison with adult ewes (1.29 and 1.56 mmol/L). Results of these investigations showed that of most exterior traits and the blood biochemical parameters (total proteins and albumine) as well as thyroid hormone (T3) were significantly affected by the age of the sheep.
