Abstract

This study examined the effects of zinc (Zn) from different sources and microbial phytase on the broiler performance, biochemical parameters and digestibility of nutrients when they were added to broiler diets containing low available phosphorus. A total of 875, 1-day-old male broilers of the Ross 308 strain were randomly separated into two control groups (positive and negative) and five treatment groups each containing 125 birds; each group was divided into 5 replicates of 25 birds. The positive control (PC) group was fed a diet containing adequate concentration (0.45 %) of available phosphorus due to mineral premix (except zinc) and feeds. The negative control (NC) group was fed a basal diet including low concentration (0.30%) of available phosphorus due to mineral premix (except zinc) and feeds. The basal diet was supplemented with 0.30% phosphorus and 500 FTU phytase (PH); 0.30% phosphorus and organic zinc (OZ; 75 mg/kg of Zn from Zn-proteinate); 0.30% phosphorus and inorganic zinc (IZ; 75 mg/kg of Zn from ZnSO4); 0.30% phosphorus, organic zinc and 500 FTU phytase (OZ + PH); and 0.30% phosphorus, inorganic zinc and 500 FTU phytase (IZ + PH) in the treatment groups 1, 2, 3, 4 and 5, respectively. The lowest value for mean body weight was in the negative control group on a diet containing low available phosphorus. The use of supplementation with organic and inorganic zinc alone or in combination with microbial phytase significantly (P<0.05) increased the digestibility of Zn in the male broilers. Supplementation of those diets with OZ + PH or IZ + PH was very effective for increasing the body weight, body weight gain and the feed conversion ratio. In conclusion, the effects on broilers of diets with low phosphorus levels may be overcome by the addition of inorganic or organic zinc compounds in combination with microbial phytase.

Özet

Bu araştırma, düşük fosforlu diyetlere organik ve inorganik çinko ile mikrobiyal fitaz ilavesinin broilerlerde performans, biyokimyasal parametreler ve besin madde kullanımı üzerine etkisini araştırmak amacıyla yapılmıştır. Araştırmada hayvan materyali olarak toplam 875 adet günlük civciv denemeye alınmıştır. Her grupta 125 adet hayvan olacak şekilde, iki kontrol (pozitif ve negatif ) ve beş deneme grubu oluşturulmuştur. Her grup 5 alt gruptan, her alt grupta ise 25 civcivden oluşturulmuştur. Pozitif kotrol grubu, çinko içermeyen mineral ön karması ve yeterli miktarda yararlanılabilir fosfor (%0.45) içeren rasyonla beslenmiştir. Negatif kontrol grubu ise, çinko içermeyen mineral ön karması ve düşük fosfor (%0.30) içeren temel bir rasyonla beslenmiştir. Temel rasyona %0.30 fosfor ve 500 FTU fitaz ilave edilmiştir (PH). Deneme grupları 1, 2, 3, 4 ve 5 ise sırasıyla %0.30 fosfor ve organik çinko (OZ; 75 mg/kg Zn-proteinat); 0.30% fosfor ve inorganik çinko (IZ; 75 mg/ kg ZnSO4); 0.30% fosfor, organik çinko ve 500 FTU fitaz (OZ + PH); ve 0.30% fosfor, inorganik çinko ve 500 FTU fitaz (IZ + PH) oluşturmuştur. Düşük fosfor içeren negatif kontrol grubunda en düşük canlı ağırlık belirlenmiştir. Organik çinko ve inoganik çinko ile mikrobiyal fitaz kombinasyonunda çinkonun sindirilebilirliği artmıştır. Rasyonlarına OZ + PH ve IZ + PH ilave edilen gruplarda canlı ağırlık ve canlı ağırlık artışı artarken, yemden yararlanma oranı olumlu yönde etkilenmiştir. Sonuç olarak, düşük fosforlu diyetlerle beslenen broylerlerde organik ve inorganik çinkonun mikrobiyal fitaz ile kombinasyonlarının yeterli olacağı kanısına varılmıştır.
