Abstract

This study was performed to investigate the effects of stocking density, dietary energy level and carnitine supplementation on performance, total costs, egg sale prices and profit of laying hens. One hundred seventy six, 32 weeks of age, Bovans white laying hens were used in the study. At the beginning of the study, hens were distributed to 8 groups with 4 replicates, hens in 4 groups were placed at the density of 500 cm2/hen and in the remaining 4 groups were placed at the density of 287.5 $cm^2$/hen. Hens were fed either basal diet (low; 2650 kcal/kg ME or high; 2850 kcal/ kg ME) or basal diet supplemented with 200 ppm carnitine. Treatments were not effected the live weight, egg production and egg weight (p>0.05). Feed intake was significantly decreased and feed efficiency was significantly increased (p

Özet

Bu çalışma, yumurta tavuklarında farklı yerleşim sıklığı, enerji düzeyi ve rasyona karnitin ilavesinin performans, toplam maliyetler, yumurta satış geliri ve kâr üzerine etkilerinin araştırılması amacıyla gerçekleştirilmiştir. Araştırmada 32 haftalık, 176 adet beyaz Bovans ırkı yumurta tavuğu kullanılmıştır. Tavuklar çalışma başlangıcında 4 tekrarlı 8 gruba ayrılmış, grupların 4’ünde tavuklar 500 $cm^2$/tavuk olacak şekilde yerleştirilirken, diğer 4’ünde ise 285.7 $cm^2$/tavuk olacak şekilde yerleştirilmiştir. Tavuklar ya bazal diyet (düşük; 2650 kcal/kg ME veya yüksek; 2850 kcal/kg ME) ya da 200 ppm karnitin ilave edilmiş bazal diyet ile beslenmiştir. Uygulamalar, canlı ağırlık, yumurta verimi ve yumurta ağırlığını etkilememiştir (p>0.05). Yüksek düzeyde enerji içeren yemlerle beslenen gruplarda yem tüketimi önemli oranda azalmış, yemden yararlanma oranı ise artmıştır (p
