Effects of L-carnitine supplementation to the diets containing different levels of energy on performance and some blood parameters of quails

Abstract

This experiment was carried out to determine the effects of the usage of L-carnitine in diets with different levels of energy on some productive characteristics and blood parameters of Japanese quail. A total of 204 quail chicks aged one week (Coturnix coturnix Japonica) were used. They were divided into four groups each containing 51 quail chicks. Diets having normal (3000 kcal/kg) and low (2700 kcal/kg) metabolizable energy level were supplemented with 0 and 100 mg/kg L-carnitine. Diets were formulated to be isonitrogenic. The experimental period lasted five weeks. L-carnitine supplementation to the diets having normal energy level did not affect the live weight at the end of the experiment, total live weight gain, feed intake per one kg live weight gain and carcass yield but increased total feed intake (p

Farklı enerji düzeylerindeki rasyonlara L-karnitin ilavesinin bıldırcınlarda performans ve bazı kan parametreleri üzerine etkisi

Abstract

Bu araştırma, farklı enerji düzeylerindeki rasyonlarda L-karnitin kullanımının Japon bıldırcınlarında performans özellikleri ve bazı kan parametreleri üzerine etkilerini belirlemek amacıyla yapılmıştır. Denemede toplam 204 adet bir haftalık Japon bıldırcın civcivi (Coturnix coturnix Japonica) kullanılmıştır. Her biri 51 adet bıldırcın civcivi kapsayan 4 grup düzenlenmiştir. Normal (3000 kcal/kg) ve düşük (2700 kcal/kg) metabolize olabilir enerji düzeyine sahip karma yemlere 0 ve 100 mg/kg L-karnitin ilave edilmiş ve ham protein düzeyleri eşit olacak şekilde düzenlenmiştir. Deneme 5 hafta sürdürülmüştür. Normal enerji düzeyine sahip rasyona L-karnitin ilavesi ile bıldırcınlarda deneme sonu canlı ağırlık, toplam canlı ağırlık artışı, bir kg canlı ağırlık artışı için tüketilen yem miktarı ve karkas randımanı etkilenmemiş, fakat toplam yem tüketimi artmış (p
