Broyler hindi rasyonlarına L-karnitin ilavesinin performans, kan parametreleri ve bağışıklık sistemi üzerine etkileri

Abstract

Bu araştırma, hindi yemlerine farklı düzeylerde (0, 50, 100 ve 150 mg/kg) L-karnitin katılmasının verim özellikleri, bazı kan parametreleri ve bağışıklık sistemi üzerine etkilerini belirlemek amacıyla yapılmıştır. Araştırmada hayvan materyali olarak toplam 48 adet 6 haftalık dişi palaz kullanılmıştır. Deneme her biri 12 adet dişi palazdan meydana gelen 1 kontrol ve 3 deneme olmak üzere toplam 4 grup halinde yürütülmüştür. Her grup 3 dişi palazdan oluşan 4 tekrar grubuna ayrılmıştır. Birinci, ikinci ve üçüncü deneme grupları rasyonlarına sırasıyla 50, 100 ve 150 mg/kg düzeylerinde L-karnitin ilavesi yapılmıştır. Kontrol grubu rasyonuna L-karnitin ilave edilmemiştir. Araştırma 10 hafta sürdürülmüştür. Araştırma sonunda yemlere farklı düzeylerde katılan karnitinin hindilerde canlı ağırlık, canlı ağırlık artışı, yem tüketimi, yemden yararlanma oranı, karkas randımanı, iç organ ağırlıkları ve abdominal yağ ağırlığı ile oranlarını, ince bağırsak pH'sı ve kan serumunda toplam protein, kolesterol, trigliserit, alanin amino transferaz, aspartat amino transferaz ve alkalin fosfataz düzeyleri üzerine etkisi gözlenmemiştir. Hindilerde karnitinin bağışıklık sistemi üzerinde de herhangi bir etkisi olmadığı görülmüştür. Sonuç olarak, yemlere 50, 100 ve 150 mg/kg düzeylerinde L-karnitin ilavesinin broyler dişi hindilerde verim özellikleri, bazı kan parametreleri ve bağışıklık sistemi üzerinde önemli bir etkisi saptanmamıştır

The effects of dietary supplementation of L-carnitine on performance, blood parameters and immunesystem in broiler turkeys

Abstract

This experiment was carried out to determine the effects of different levels of L-carnitine (0, 50, 100 and 150 mg/kg) added to the broiler turkey diets on performance characteristics, some blood parameters and immune system. A total of 48 female poults aged 6 weeks were used in this experiment. They were divided into one control group and three treatment groups each containing 12 female poults. Each group was divided into four replicate groups each containing 3 poults. The diets of the first, second and third treatment groups were supplemented with 50, 100 and 150 mg/kg L-carnitine, respectively. L-carnitine was not added to the diet of control group. The experimental period lasted 10 weeks. At the end of the experiment live weight, live weight gain, feed consumption, feed efficiency, carcass yield, weights and rates of internal organs and abdominal fat, pH value of small intestine and total protein, cholesterol, trigliceride, and activities of alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase of blood serum were not affected by different levels of carnitine supplementation to diets. Immune system of female poults was not affected by dietary L-carnitine. The results in this study demonstrated that L-carnitine supplementation at the levels of 50, 100 and 150 mg/kg to the diets of female poults did not have any significant effects on performance characteristics, some blood parameters and immune system
