Abstract |
The objective of this study was to find zinc (Zn) concentration in blood
and different tissues in Baluchi lambs fed different levels of organic
and inorganic sources of this element. Thirty-six male growing lambs
with an average weight 26.5±0.3 kg were divided into six groups and fed
basal diet (no Zn supplementation, BD), 50 or 100 ppm zinc sulphate
monohydrate (Zn-S), zinc proteinate (Zn-P) and their mixture (Zn-P+S, 50
mg/kg each). Results showed that serum Zn concentration was
significantly (P<0.05) high in lambs fed 100 mg/kg Zn-P or mixture of
Zn-P-S at the rate of 50 mg/kg each. Zn in heart and testis was
significantly (P<0.05) high in lambs fed Zn-S (100 mg/kg) and Zn-P-S. In
kidney, liver, muscle and spleen, Zn concentration was significantly
(P<0.05) high in lambs fed with Zn-P, Zn-S and Zn-P-S. The results
showed that Zn fed as organic source at the level of 100 mg/kg or at the
rate of 50 mg/kg in combination with ZnSO 4 showed higher
bioavailability in serum and tissues.
