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

Öz

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.

Laktasyon Döneminin Sonunda Merada Beslenen Farklı Yaşlardaki Norduz Keçilerinin Kan Mineral Seviyelerinin Karşılaştırılması

Öz

Bu çalışma Van Yüzüncü Yıl Üniversitesi Araştırma ve Uygulama Çiftliği'nde (Van, Türkiye) merada beslenen toplam 26 Norduz keçisinin (1. laktasyon sonunda (n=10), 2. laktasyon sonunda (n=8) ve 3. laktasyon sonunda (n=8)) kanındaki bazı makro ve mikro mineral düzeylerinin belirlenmesi amacıyla yapıldı. Bu amaçla Haziran ayı başında laktasyon dönemini tamamlamış keçilerden usulüne uygun olarak kan örnekleri alındı. Keçilerden toplanan kan örneklerinden elde edilen bazı makro minerallerin düzeyleri (potasyum (K), magnezyum (Mg), kalsiyum (Ca), sodyum (Na)) ve bazı mikro minerallerin düzeyleri (cobalt (Co), bakır (Cu), demir (Fe), nikel (Ni), manganez (Mn), selenyum (Se), çinko (Zn), kurşun (Pb),) keçilerden toplanan kan örneklerinden elde edilen serum örnekleri endüktif olarak eşleşmiş plazma optik emisyon spektrometresi (ICP-OES) ile belirlendi. Sonuçlar SPSS 24.0 versiyonu (IBM SPSS Inc, Chicago, ABD) kullanılarak tüm istatistiksel analizlere tabi tutuldu (SPSS, 2016). İstatistiksel olarak anlamlı tüm farklılıklar (P<0.05) Duncan'ın Çoklu Aralık Testi ile karşılaştırıldı ve sıralandı. Daha sonra mineraller arasındaki ilişkiler Pearson Korelasyon Katsayısı (P≤0.05) ile ortaya konuldu. Ayrıca bu çalışmada makro ve mikro minerallerin sıralaması ve bu minerallerden bazılarının oranları da (Ca/Mn, Ca/Mg, Ca/Zn, Cu/Fe, Cu/Zn, Fe/Mn, Fe/Zn, K/Mg, K/Na, K/Mn) sunuldu.
