Eficacy of tribasic copper chloride (TBCC) to reduce the harmful effects of aflatoxin in broilers

Bu çalışma, yemleriyle aflatoksin alan broylerlerin yemlerine üç bazlı bakır klorid halinde ilave edilen bakırın, serum biyokimyasal değerleri ile büyüme performansı üzerine etkilerinin incelenmesi amacıyla yapıldı. Aflatoksin serum albumin (P < 0,001), toplam protein (P < 0,001).ve toplam kolesterol (P < 0,01) düzeylerini önemli oranda azaltırken; serum alanin aminotransferaz, L-laktik dehidrogenaz ve alkalen fosfataz aktivitelerini önemli oranlarda (P < 0,001) artırdı. Bu değişiklikler üç bazlı bakır klorid ilavesi ile düzeltildi. Aflatoksine bağlı olarak serum bakır konsantrasyonunda meydana gelen azalma üç bazlı bakır klorid ile düzeltildi. Serum Zn konsantrasyonları üç bazlı bakır klorid ve aflatoksin+üç bazlı bakır klorid gruplarında etkilenmedi. Tüm uygulama gruplarında serum demir konsantrasyonlarında önemli düzeyde (P < 0,05) azalma oldu. Aflatoksin grubunda canlı ağırlık artışında önemli bir azalma ve yemden yararlanma oranında ise önemli bir artış belirlendi. Aflatoksininin yemden yararlanma oranında meydana getirdiği olumsuz etki üç bazlı bakır klorid ilavesi ile tersine döndürüldü. Sonuçta, broyler yetiştiriciliğinde aflatoksinlerin zararlı etkilerinin önlenmesinde yeme üç bazlı bakır klorid ilavesinin yararlı olabileceği kanısına varıldı.

Broyler yetiştiriciliğinde aflatoksinlerin zararlı etkilerinin önlenmesinde üç bazlı bakır kloridin (TBCC) faydaları

This study was conducted to evaluate the effects of copper as tribasic copper chloride on serum biochemical values and growth performance of broilers intoxicated with aflatoxins. Anatoxins significantly decreased the level of albumin (P < 0.001), total protein (P < 0.001) and total cholesterol (P < 0.01), and increased the activities of alanine amino transferase, L-lactic dehydrogenase and alkaline phosphatase (P < 0.001) in serum. These AF-induced changes were significantly improved by adding tribasic copper chloride to the diet. The decrease in serum copper concentration induced by afiatoxin was reversed by tribasic copper chloride. Serum zinc concentrations were not affected in tribasic copper chloride and tribasic copper chloride plus afiatoxin groups. Serum iron levels decreased in all the treatment groups significantly (P < 0.05). Aflatoxins caused significant decrease in the body weight gain and significant increase in the feed conversion ratio. Adverse effects of aflatoxins on feed conversion ratio were reversed by tribasic copper chloride supplementation to the diet. It is suggested that tribasic copper chloride might be used for reducing the adverse effects of aflatoxins in broiler production.
