Özet
Bu araştırmada, merinos kuzularda rasyona çinko (Zn) ve bakır (Cu) ilavesinin bazı kan metabolitleri üzerindeki etkileri incelendi. Bu amaçla, yaklaşık 3,5 aylık ve 26 kg. canlı ağırlığında toplam 24 adet erkek kuzu kullanıldı. Hayvanlar eşit olarak dört gruba ayrıldı. Beş ay boyunca, gruplardan biri kontrol rasyonu ile beslenirken, diğerleri sırasıyla Zn (kuru maddede 250 mg/kg), Cu (kuru maddede 25 mg/kg) ve aynı miktarlarda Zn ile kombine olarak Cu ilave edilen rasyonla ad libitum olarak beslendiler. Kan örnekleri ayda bir olmak üzere beş ay süre ile vena jugularis' den alındı ve plazmaları elde edildi. Rasyonlarına Zn ve Zn ile birlikte Cu ilave edilenlerin plazma Zn düzeyleri, diğer gruplardaki hayvanların aynı değerlerinden daha fazla miktardaydı, Cu ilaveli rasyonla beslenen hayvanların plazma Cu düzeyleri, kontrol kuzuları ve Zn ilaveli rasyonla beslenenler ile karşılaştırıldığında, birinci ay haricinde genelde daha yüksekti. Zn ile kombine olarak Cu ilaveli rasyonla beslenen hayvanların ikinci ve üçüncü aylardaki plazma Cu düzeylerinin de Zn ilaveli rasyonla beslenen kuzularınkine göre daha fazla olduğu bulundu. Diğer yarıdan, rasyonuna Zn ilave edilen grubun üçüncü aydaki plazma total protein düzeyinin diğer gruplara göre daha fazla miktarda olduğu belirlendi. Kontrol grubunun beşinci ayındaki değeri ile karşılaştırıldığında, Zn ilaveli yemle beslenen grubun aynı aydaki plazma albümin düzeyinde de benzer bir artışın olduğu gözlendi. Zn ilaveli rasyonla beslenen grupta ikinci, dördüncü ve beşinci aylarda ölçülen plazma total kolesterol miktarı kontrol grubundakilere göre daha az miktardaydı. Sonuç olarak, bu araştırmada rasyona Zn ilavesinin kuzuların plazma total protein, albümin ve total kolesterol düzeylerinde değişiklere neden olmasına karşın, Cu ve Zn ile kombine olarak Cu ilavesinin önemli bir etkisinin olmadığı belirlendi.
In this study, the effects of supplementation of zinc (Zn) and copper (Cu) to the ration on some blood metabolites of merino lambs were investigated. For this purpose, 24 male lambs, which were about 3.5 months old and 26 kg in body weight, were used. The animals were equally divided into four groups. Over five months, while one of the groups was fed the control ration, the others were fed rations supplemented with Zn (250mg/kg in DM), Cu (25 mg/kg in DM) and the same amounts of Zn plus Cu ad libitum. Blood samples were taken from the vena jugularis at one month intervals over five months and their plasma levels were obtained. Plasma Zn levels of the lambs fed the ration supplemented with Zn and Zn plus Cu were higher than those of the animals in the other groups. When compared with the control lambs and the ones fed the ration with Zn added, the plasma Cu levels, except during the first month, generally increased in the animals fed the ration with Cu added. It was found that the plasma Cu levels of the animals fed the Zn plus Cu supplemented ration were also higher than those of the lambs fed the Zn supplemented ration in the second and third months. On the other hand, it was determined that the group with Zn added to the ration in the third month had higher plasma total protein levels than the other groups. In addition, when compared to the value of the control group in the fifth month, a similar increase was seen in the plasma albumin level in the group supplemented with Zn in the same month. The determined total cholesterol levels of the lambs fed the diet supplemented with Zn in the second, fourth and fifth months were lower than those of the control animals. Consequently, it was determined that Zn supplementation to the ration caused differences in the plasma total protein, albumin and total cholesterol levels of the lambs. Cu and Zn in combination with Cu supplementation had no significant influence.
