Abstract

Lead is one of the ubiquitous environmental pollutants that induce a broad range of physiological and biochemical dysfunctions in animals. This study evaluated the effects of dietary lead exposure and ascorbic acid on performance, serum biochemical parameters, plasma malondialdehyde and lead accumulation in broiler chickens. For this purpose, lead acetate at 200 mg/kg and ascorbic acid at 100 mg/kg were added to the diet alone or in combination for 42 days. A total of 120 broiler chicks were divided into 4 treatment groups: control, ascorbic acid, lead, and lead + ascorbic acid. By the end of the study, lead caused body weight and body weight gain to decrease significantly, although its effects on feed consumption and the feed conversion ratio were not significant. While lead did not alter thep serum lactate dehydrogenase, aspartate aminotransferase or alanine aminotransferase activities or albumin or total protein concentrations, it increased malondialdehyde (P < 0.001) and triglyceride (P < 0.01) levels. Although the lead contents of the serum and muscle were unchanged, lead was accumulated in the liver and kidneys (P < 0.001). Our results showed that lead (200 mg/kg diet) had an inhibitory effect on the growth of broilers and appeared to be inducing lipid peroxidation. The addition of ascorbic acid to the diet reduced the plasma malondialdehyde levels induced by lead and tended to reduce the inhibitory effect of lead on growth. It is concluded that the addition of higher doses of ascorbic acid to the diet may be more efficacious in fully reversing the negative effect of lead on growth.

Özet

Kurşun hayvanlarda fizyolojik ve biyokimyasal fonksiyon bozuculuklarına yol açan, yaygın bulunan çevre kirleticilerden biridir. Bu araştırmada broyler piliçlerin yemle kurşuna maruz kalmasının ve askorbik asit ilavesinin performans, serum biyokimyasal parametreler ile plazma malondialdehid seviyesi ve kurşun birikim düzeyi üzerine etkisi belirlendi. Bu amaçla, kurşun asetat 200 mg/kg ve askorbik asit 100 mg/kg oranında ayrı ayrı ve birlikte 42 gün süreyle karma yeme katıldı. Araştırmada 120 adet broyler civciv 3'er alt gruplu: kontrol, askorbik asit, kurşun ve kurşun + askorbik asitten oluşan 4 gruba ayrıldı. Araştırma sonunda kurşun ilavesi, canlı ağırlık ve canlık ağırlık artışında belirgin düşüklüğe neden oldu (P < 0,05). Yem tüketimi ve yemden yararlanma oranı, kurşun ve askorbik asidin ayrı ayrı ve birlikte katılmasından etkilenmedi. Kurşun, serum laktat dehidrojenaz, aspartat aminotransferaz, alanin aminotransferaz aktivitesi, albumin ve total protein konsantrasyonunu etkilemezken, malondialdehid (P < 0.001) ve trigliserid (P < 0,01) seviyesini belirgin olarak yükseltti. Serum ve kas kurşun düzeyi değişmezken, kurşun, böbrek ve karaciğerde birikim yaptı (P < 0,01). Bu araştırma sonucunda, kurşunun (200 mg/kg yem) broylerlerde büyümeyi baskıladığı ve plasma malondialdehid seviyesini yükselttiği belirlenmiştir. Yeme katılan askorbik asit kurşunun neden olduğu lipid peroksidasyonunu düşürmüş ve kurşunun büyümeyi baskılayıcı etkisini azaltma eğiliminde olduğu belirlenmiştir. Rasyona daha yüksek dozlarda askorbik asit katılmasının kurşunun büyüme üzerine olan olumsuz etkisinin tamamen giderilmesinde etkili olabileceği sonucuna varılmıştır.
