Abstract
The aim of the investigation was to determine
influence of dietary supplementation with selenium on blood metabolic profile
and thyroid hormones activities in fattening lambs. The study included 36 Merinolandschaf lambs during
fattening period (50 days) divided
into three groups (control, Exp-I and Exp-II).
The
control group diet was not supplemented with Se, whereas the diet of Exp-I was
supplemented with 0.3 mg/kg inorganic selenium (sodium selenite) and Exp-II with
0.3 mg/kg organic selenium (Sel-Plex). Concentration of minerals (Ca,
P-inorganic, K, Na, Fe and Cl), biochemical indicators (urea, glucose,
cholesterol, HDL-cholesterol, LDL-cholesterol, triglycerides, creatinine, total
protein, albumin), enzyme activity (ALT, AST, GGT, LDH and GSH-Px) and
thyroid hormone activities (T3, T4)
were determined.
Significantly higher (P<0.01)
selenium content and
GSH-Px
activity as well as the lower content of
Ca was determined in the blood
of Exp-II and Exp-I groups
compared to control group (93.89 and 67.69: 34.11 µg L-1;
607.98 and 556.92: 247.52 µkat L-1; 2.38 and 2.39: 2.76 mmol L-1).
Significantly higher (P<0.01)
selenium content in the in blood
of lambs from Exp-II compared to
Exp-I group was determined.
Significantly higher (P<0.05)
concentrations of HDL-cholesterol
and T3 hormone
activity were found in Exp-II group
compared to the Exp-I and
control groups. The results showed lower blood selenium
content in control group and indicate the
justification of adding
selenium, especially organic
selenium in
lamb’s diets, raising the concentration of Se, GSH-Px enzyme,
HDL-cholesterol and T3 hormones improving the health status,
especially in areas deficient in
selenium.
