Etlik Piliçlerde Bazı Civciv Kalite Ölçütlerinin Besi Performansı Üzerine Etkileri

Bu çalışma, etlik piliç civcivlerinde 4 farklı kalite ölçütünün (civciv ağırlığı, parmak uzunluğu, incik uzunluğu ve boy uzunluğu) besi dönemi sonundaki canlı ağırlık, yem tüketimi, yemden yararlanma ve ölüm oranı üzerine etkisini incelemek amacıyla yürütülmüştür. Denemede toplam 192 adet erkek etlik piliç civcivi kullanılmış olup, her bir kalite ölçütü için iki farklı grup oluşturulmuştur. Günlük civcivlerde vücut ağırlığı için ağır ve hafif (≥47.7 ve <47.7 g); parmak uzunluğu (≥2.01 ve <2.01 cm), incik uzunluğu (≥2.9 ve <2.9) ve boy uzunluğu için uzun ve kısa (≥18.3 ve <18.3) olmak üzere ikişer grup oluşturulmuştur. Altı haftalık besi dönemi sonunda; ağır vücut grubu hafif gruba, kısa parmak grubu uzun parmak grubuna, kısa boy grubu uzun boy grubuna göre önemli (P<0.01 ve P<0.01) düzeyde yüksek canlı ağırlığa sahip olmuşlardır. Yem tüketimi bakımından ağır vücut grubu hafif gruba, kısa incik uzunluğu grubu uzun gruba ve kısa boy grubu ise uzun boy grubuna oranla daha fazla (P<0.01) yem tüketmiştir. Yemden yararlanma düzeyleri, kalite ölçütlerinden etkilenmiş olup ağır vücut grubu hafif gruba, kısa parmak grubu uzun parmak grubuna ve kısa boy grubu uzun boy grubuna oranla daha iyi yemden yararlanmıştır. Deneme gruplarına ait ölüm oranları ise, incik uzunluğu grubu dışındaki gruplarda önemli (P<0.05) düzeyde farklılıklar göstermiştir.

Effects on Growth Performance of Some Chick Quality Measurements in Broilers

This study was conducted to examine the effect of 4 different quality criteria (chick weight, toe length, shank length and chick length) on live weight, feed consumption, feed conversion ratio and mortality in broiler chicks at the end of the fattening period. A total of 192 male broiler chicks were used in the experiment, and two separate groups were formed for each quality criterion. In 1 day-old chicks, a heavy group and a light group (≥47.7 g and <47.7 g) were created for chick weight; and a tall group and a short group were created for each of the toe length (≥2.01 cm and <2.01 cm), shank length (≥2.9 cm and <2.9 cm) and chick length (≥18.3 cm and <18.3 cm) criteria. At the end of the six-week fattening period, the live weight was significantly higher in the heavy group compared to the light group; in the short toe group compared to the tall toe group; and in the short chick length group compared to the tall chick length group (P<0.01 and P<0.01). In terms of feed consumption, more feed was consumed in the heavy group compared to the light group; in the short shank group compared to the tall shank group; and in the short chick length group compared to the tall chick length group (P<0.01). The feed conversion ratios were influenced by the quality criteria, and the feed efficiency was better in the heavy group compared to the light group; in the short toe group compared to the tall toe group; and in the short chick length group compared to the tall chick length group. The mortality of the experimental groups showed significant differences in the groups other than the shank length group (P<0.05).
