Comparison of growth curves of broiler under different stocking densities by Gompertz model

Öz:

Kanatlı biliminde büyüme eğrisinin bilinmesi büyümenin tarifinde ve yetiştirme tekniklerinin uygulanmasında çok önemlidir. Bu araştırmanın amacı kuluçkadan 42. gün ağırlığına kadar üç yerleşim sıklığında yetiştirilen etlik piliçlerden elde edilen canlı ağırlıkları, Gompertz büyüme eğrisi modeli ile tahmin etmektir. Denemede 3 yerleşim sıklığında (9, 13 ve 17 etlik piliç/m2) tesadüfen dağıtılan toplam 284 adet Ross 308 etlik piliç kullanılmıştır. Bütün hayvanlar haftalık olarak tartılmıştır. 9, 13 ve 17 etlik piliç/m2 yerleşim sıklığında etlik piliçlerin, asimptotik ağırlıkları (A) sırasıyla; 4198.46, 3807.45 ve 3999.92 g olarak (P<0.05); büyüme oranı (K) sırasıyla 0.055, 0.058 ve 0.052 olarak (P<0.01) tahmin edilmiştir. Tüm yerleşim sıklıklarında belirtme katsayısı değeri (R2) sırasıyla 0.998, 997 ve 0.996 olarak bulunmuştur (P<0.05). Ek olarak hata kareler ortalaması (MSE) yerleşim sıklığı 9/m2 olan grupta en düşüktür (P<0.05). Bu çalışmanın sonucunda tahmini ergin canlı ağırlığa (A), belirtme katsayısı değeri (R2) ve hata kareler ortalamasına (MSE) göre 9 etlik piliç/m2 olan yerleşim sıklığında etlik piliçlerin büyümelerinin daha iyi olduğu söylenebilir.

Öz:

The knowledge of the growth curve in poultry science is very useful for describing growth kinetics and setting commercial management procedures. The objective of this research was to fit the Gompertz growth curve from hatching weights to 42 d-old weights of broilers in 3 stocking density groups. A total of 284 Ross 308 broilers randomly divided into 3 stocking density groups (9, 13 and 17 birds/m2) in this experiment. All birds were weighted weekly. The asymptotic weight (A) of broiler chickens for 9, 13 and 17 bird/m2 stocking density groups were 4198.46, 3807.45 and 3999.92 g, respectively (P<0.05). The growth rates (K) of broiler chickens for 9, 13 and 17 bird/m2 stocking density groups were 0.055, 0.058 and 0.052, respectively (P<0.01). The coefficient of determination for all stocking density groups were 0.998, 0.997 and 0.996, respectively (P<0.05). Moreover, the mean square error (MSE) value was lowest for 9 bird/m2 group (P<0.05). The current study suggested that stocking density of 9 bird/m2 was better for the broiler growth of the different stocking densities on the base of mature live weight (A), coefficient of determination (R2) and mean square error (MSE).
