The Effects of Lower Supplementation Levels of Organically Complexed Minerals (Zinc,Copper and manganese) versus inorganic forms on hematological and biochemical parameters in broilers

Bu araştırma inorganik formları yerine daha düşük seviyelerde organik mineral tüketiminin etçi piliçlerin hematolojik ve biyokimyasal parametreleri üzerine etkilerini belirlemek amacıyla yapıldı. Çalışmada 200 adet, bir günlük yaşta, etçi civciv (Ross-308) kullanıldı. Civcivler, 10’ar civciv bulunan 5 alt gruptan oluşan, biri kontrol diğer üçü deneme grubu olmak üzere 4 ana gruba tesadüfi olarak dağıtıldı. Kontrol grubunun diyeti, NRC tarafından belirtilen ticari etçi piliç yemi normlarına göre kg’da 40 mg Zn ($ZnSO _4$), 8 mg Cu ($CuSO _4$) ve 60 mg Mn (MnO) olacak şekilde hazırlandı. Üç deneme grubunun diyetlerine ise inorganik formdaki Zn, Cu ve Mn mineralleri yerine sırasıyla 1/3 (1. Grup-L1), 2/3 (2. Grup-L2) ve 3/3 (3. grup-L3) oranında organik Zn, Cu ve Mn (BioplexTM) ilavesi yapıldı. Araştırma sonunda, NRC normlarının 2/3’ü ve 3/3’ü oranlarında organik mineral tüketen etçi piliçlerin plazma çinko seviyesi önemli oranda artarken, plazma bakır seviyesi önemli oranda düştü (P

İnorganik formları yerine daha düşük seviyelerde organik mineral (çinko, bakır ve mangan) ilavesinin etçi piliçlerde bazı hematolojik ve biyokimyasal parametreler üzerine etkisi

The present study was carried out to investigate the effects of replacing inorganic with at lower level of organically complexed minerals (Zn, Cu and Mn) on hematological and biochemical parameters in broilers. A total of two hundred Ross-308 one-day-old broiler chickens were used. Chicks were randomized into 1 control and 3 treated groups each containing 50 chicks and each experimental group comprised 5 of subgroups including 10 chicks. Mineral content of the control diet was prepared according to National Research Council (NRC) as inorganic salts. In treated groups, organically complexed Zn, Cu and Mn were separately added into the basal diet at 1/3 (group 1), 2/3 (group 2) and 3/3 (group 3) proportions as $Bioplex^ {TM}$, instead of inorganic levels of those minerals recommended by NRC, respectively. The plasma Zn level significantly increased as the serum Cu level significantly decreased (P<0.05) in chickens fed at 2/3 and 3/3 levels of organic minerals. The hemoglobin concentration and packed cell volume were significantly higher in group L1. Total leukocyte count and peripheral blood leukocyte type were in the normal range reported in both the control and organic mineral supplemented groups. As the high density lipoprotein (HDL)-cholesterol level increased, low density lipoprotein (LDL)-cholesterol and total cholesterol levels decreased in chickens fed organically complexed minerals. Results showed that using at much lower level organically complexed minerals (Cu, Zn and Mn) in broiler diets instead of inorganic forms of those minerals has not created a negative impact on hematological and biochemical parameters.
