Abstract

An experiment was conducted in order to estimate the ME value of full-fat soybean processed with wet extrusion using 480 day old mixed sexes ROSS broiler chicks. Three dietary treatments were formulated assuming the full-fat soybean to have three ME values (3300, 3500, 3700 Kcal/kg). Broiler diets (starter, grower and finisher) were mixed isocaloric and isonitrogenous according to Ross (2002) recommendations and were fed as ad libitum. Eight replicate groups of 10 day old broiler chicks were randomly assigned to each of 3 treatments in two blocks. Ten birds were placed in each of the experimental cages with wire floor and equipped with nipple drinkers and trough, feeders. The experiment was set up according to completely randomized blocks. Chicks were given 23 h light and 1 h dark throughout the 42 day experimental period. The results of the present experiment indicated that broilerperformance was significantly (P<0.05) affected by the given different ME values of full-fat soybean. Body weight, feed intake, weight gain and European Efficiency Index of the group fed with 3700 Kcal ME/kg were significantly (P<0.05) lower than the other two groups fed with 3300 and 3500 Kcal ME/kg values. Body weight of the experimental groups were respectively, 2302, 2344 and 1965 g during the 42 day experimental period. European Efficiency Index of the group fed with 3700 Kcal ME/kg was significantly (P<0.05) lower than the other two groups (3300 and 3500 Kcal ME/kg) being 276, 322 and 332, respectively. In conclusion, full-fat soybean processed with wet extrusion was estimated to have an ME value of between 3300-3500 Kcal/kg and averagely 3400 Kcal ME /kg. To estimate the ME value of a full-fat soybean a broiler performance trial can be considered reliable.

Özet

Tam yağlı soyanın (TYS) metabolik enerjisi (ME) bilimsel literatürde 3300 den 3900 Kcal/kg a kadar değişen değerler almaktadır. Belirli bir köken (ABD) ve işleme yöntemine (ekstrüzyon) sahip tam yağlı soyanın ME değerini belirlemek üzere broyler civcivlerle bir araştırma denemesi düzenlenmiş ve broyler performansından ME değerinin tahminine çalışılmıştır. Bunun için TYS'nin 3300, 3500-ve 3700 Kcal ME/kg içerdiği varsayılarak broyler başlatma (%23 H.Protein; 3010 Kcal ME/kg), büyütme (%21 H. Protein; 3175 Kcal ME/kg) ve bitirme (%19 H. Protein; 3225 kcal ME/kg) rasyonları formüle edilerek, sırasıyla 0-14, 15-28 ve 29-42. günler arasında ROSS ırkı erkek-dişi karışık civcivlere yedirilmiştir. Deneme şansa bağlı tam bloklar deneme desenine uygun olup, civcivler her 3 muameleye 8 er teker-rüilü ve iki blok halinde ve her tekerrürde 10 adet olacak şekilde şansa bağlı olarak dağıtılmıştır. Deneme yemleri ve su civcivlere serbest olarak verilmiştir. Deneme odaları 23 saat aydınlık ve 1 saat karanlık olacak şekilde aydınlatılmıştır. Deneme 42 gün sürmüştür. Toplanan veriler varyans analizi ve Duncan's Multiple Range testlerine tabi tutulmuştur. Deneme sonucunda TYS'nin ME değerinin 3700 alınması halinde, yem tüketiminin azaldığı ve buna bağlı olarak 3300 ve 3500 değerlerine göre 42 günlük canlı ağırlık ve besi süresince elde edilen ağırlık kazançlarında istatistik olarak önemli (P<0.05) düşmeler meydana geldiği görülmüştür. 3300, 3500 ve 3700'lü gruplarda canlı ağırlık sırasıyla 2302, 2344 ve 1965 gram olarak bulunmuştur. Yem dönüşüm oranlan (1.649; 1.630; 1.647), karkas randımanları (%75.8, 76.6 ve 75.3) ve abdominal yağ (% 1.63, 1.79 ve 1.49) oranında muameleler arası önemli bir farklılık çıkmadığı halde, Avrupa İndeksi 3700'lü grupta (276) diğerlerine (322 ve 332) göre önemli derecede (P<0.05) daha düşük çıkmıştır. Bu denemenin sonucunda denemeye alınan TYS'nin ME değerinin 3300 ile 3500 arasında olabileceği ve ortalama olarak 340Q Kcal/kg alınabileceği sonucuna ulaşılmıştır.
