Abstract

The present experiment was conducted to describe the effects of dietary supplementation of oregano essential oil at different levels, on plasma concentrations of total and HDL cholesterol and triglycerides in broilers. A total 450 Ross 308 male chicks were used in the experiment. There were 3 dietary treatments, each consisting of ten replicates. A replicate was a cage with 15 birds so that each treatment had 150 animals.

Abstract

ÖZET

Bu araştırma, etlik piliç yemlerine farklı düzeylerde esansiyel kekik yağı (Oreganum vulgare) ilave edilmesinin plazma total kolesterol, plazma HDL kolesterol ve plazma trigliserit üzerine etkilerini belirlemek amacıyla yapılmıştır. Araştırmada; 450 adet Ross 308 erkek broyler civciv deneme materyali olarak kullanılmıştır. Biri kontrol, ikisi deneme olmak üzere üç grup oluşturulmuştur. Her bir grup 15 civcivin bulunduğu 10 tekrar grubuna ayrılmıştır. Kontrol grubundaki civcivlere başlangıç (0-21 gün) ve büyütme (21-42 gün) dönemlerinde mısır - soya ağırlıklı temel rasyon yedirilmiştir. Deneme gruplarında ise temel rasyona birinci deneme grubunda 150 ppm esansiyel kekik yağı, ikinci deneme grubunda 300 ppm esansiyel kekik yağı ilave edilmiştir. 42 gün süren deneme periyodu boyunca yem ve su ad libitum olarak verilmiştir. Denemenin 21. ve 42. günlerinde V. subcutanea ulnaris'ten kan örnekleri alınarak, plazma total kolesterol, plazma HDL kolesterol ve plazma trigliserit analizleri ticari kitler kullanılarak spektrofotometrik yöntemle yapılmıştır. Denemenin 21. ve 42. gününde alınan kan örneklerinde, plazma total kolesterol düzeylerinde gruplar arasında istatistik önemde bir farklılık gözlenmemiştir. Çalışmanın 21. ve 42. gününde alınan kan örneklerinde 300 ppm kekik yağı ilave edilen grupta plazma HDL kolesterol düzeylerinin diğer gruplara göre önemli derecede düşük (P<0,05) olduğu belirlenmiştir. Plazma trigliserit düzeyleri bakımından gruplar arasında istatistiksel açıdan farklılık saptanmamıştır.

ABSTRACT 

EFFECT OF OREGANO ESSENTIAL OIL SUPPLEMENTATION ON PLASMA LIPID CONCENTRATIONS IN BROILERS

 

The present experiment was conducted to describe the effects of dietary supplementation of oregano essential oil at different levels, on plasma concentrations of total and HDL cholesterol and triglycerides in broilers. A total 450 Ross 308 male chicks were used in the experiment. There were 3 dietary treatments, each consisting of ten replicates. A replicate was a cage with 15 birds so that each treatment had 150 animals. The control group was fed maise-soybean based diet while the other groups were fed diets supplemented with oregano essential oil at 150 and 300 ppm levels. The experiment lasted for 42 days. Feed and water were provided for ad libitum consumption. At 21 and 42 d of age, blood samples were collected from V. subcutanea ulnaris. Plasma concentrations of total and HDL cholesterol and triglycerides were measured spectrophotometrically by using commercial kits. There was no significant effect on plasma total cholesterol. At 21 and 42 days of age, plasma HDL cholesterol concentrations were significantly lower (P<0.05) in the birds given 300 ppm oregano essential oil when compared with the 150 ppm oregano essential oil group. Plasma triglyceride concentrations were not changed by any dietary treatment.
