Comparison of Blood Mineral Levels of Norduz Goats of Different Ages Fed on Pasture at the End of the Lactation Period

Abstract

This study was carried out to determine some makro and micro mineral levels in the blood of a total of 26 Norduz goats (at the end of 1st lactation (n=10), at the end of 2nd lactation (n=8), at the end of 3rd lactation (n=8)) fed in pasture at Van Yuzuncu Yil University, Research and Application Farm (Van, Turkiye). For this purpose, blood samples were duly taken from goats that had completed the lactation period at the beginning of June. Some macro mineral’s levels (potassium (K), magnesium (Mg), calcium (Ca), sodium (Na)) and some micro mineral’s levels (cobalt (Co), copper (Cu), iron (Fe), nickel (Ni), manganese (Mn), selenium (Se), zinc (Zn), lead (Pb)) in samples of serum obtained from blood samples collected from goats were determined by inductively coupled plasma optical emission spectrometry (ICP-OES). Results were subjected to all statistical analysis using SPSS 24.0 version (IBM SPSS Inc, Chicago, USA) (SPSS, 2016). All statistically significant differences (P<0.05) were compared and ranked with Duncan's Multiple Range Test. Later, the relationships between minerals were revealed by Pearson Correlation Coefficient (P≤0.05). In addition, in this study, the ranking of macro and micro minerals and the rates of some of these minerals (Ca/Mn, Ca/Mg, Ca/Zn, Cu/Fe, Cu/Zn, Fe/Mn, Fe/Zn, K/Mg, K/Na, K/Mn) were also presented.
