Merinos ve ile de France X Akkaraman (G2 melezi) koyunlarında laktasyonun değişik dönemlerinde yapağı, serum ve süt iz element düzeylerinin karşılaştırılması.
Özet
The aim of this study is to determinate wool, milk and serum trace element ( Fe,Cu, Zn, Mn, Co, Se) levels in the firs, middle and last period of lactation (forMerinos 15th, 45 th ve 75 th days, for Akkaraman hybrid 15 th, 75 th ve 150 th days) andserum trace element level after lactation to compare the levels and to find out if thereis any differences between metabolic diseasses and diseasses depending on lack oftrace elements in Merinos and Ile de France x Akkaraman (G2 hybrid) sheep.Ankara Polatlı in TİGEM the Merinos Akkaraman x Ile de France Akkaraman(G2 hybrid) sheep which has close together in age, nutrition and the maintenance ofhygienic conditions, beginner, intermediate and final stages of their lactation period,30-pieces, 60 pieces in total serum and 60 pieces of milk samples at the beginning oflactation and wool, feed and water samples were collected. Milk and serum samplingprocess was repeated three times for a total duration of lactation. Received wool,milk, feed and water samples were digested with the appropriate method inmicrowave oven; Fe, Cu and Zn analysis FL-AAS, Se, Mn and Co analysis were alsoin GF-AAS.As a result of analysis of the two races of the milk and serum Zn, Se, Mn andCo values during lactation were found to show changes parallel to each other. Serumand milk Fe values during lactation in Merinos inversely corrolated changes while inthe parallel hybrid Akkaraman a trend that the value of Cu, in Merinos duringlactation while a linear increase in Akkaraman hybrids in the middle of lactation andlactation have fallen towards the end of rising again; Merino wool in with thespecifics of the Cu and Se in terms of was significantly higher in Akkaraman hybridshave been identified. Lactation period in both races by the value of serum Cu, serumZn values at the end of lactation, although it is low in animals with any clinicalsymptoms hipokupremi and hipozinkemi not observed. Serum Co with in thereference value for the duration of lactation and remained low, but not until theclinical signs will emerge; the end of lactation serum Se values were found to watchlean limit values. Interms of trace elements serum, milk and wool levels duringlactation were not significantly related. Animals given diets during the lactation andlactation in terms of Cu and Co from the middle in terms of Zn and Se will benefitfrom reinforcing has been concluded.
