Abstract

The aim of this study was to determine the effect of probiotic supplementation on egg weight in laying hens by using meta–analysis. The limitations of the eight studies –indexed in SCI– taken into the meta–analysis were 18 – 42 week old brown and white laying hens; 10(7) – 10(10) CFU/g Bacillus subtilis was used as a probiotic and the dose ranged between 400 – 1000 g/ton. The meta–analysis was carried out using (experimental–control) means for continuous data. As a result of the research, it was determined that all studies did not share a single common effect (heterogeneous). In addition, the overall effect size using the random effect model was calculated as 0.223. Based on z and p values, the hypothesis of the study was accepted (z = 2.90; p < 0.05). In other words, "the probiotic has a significant effect on egg weight in laying hens".

Özet

Bu çalışmanın amacı, yumurtacı tavuklarda diyet probiyotik takviyesinin yumurta ağırlığı üzerindeki etkisini meta-analiz kullanarak belirlemektir. Meta analize alınan sekiz çalışmanın sınırlılıkları; SCI-exp endeksinde olması, 18-42 haftalık kahverengi ve beyaz yumurtlayan tavukların kullanılması; probiyotik olarak 10(7)-10(10) CFU / g Bacillus subtilis kullanılması ve doz olarak 400-1000 g / ton arasında değişmesiydi. Meta-analizinde, sürekli veriler için (deneysel-kontrol) ortalamalar kullanılarak etki büyüklüğü hesaplanmıştır. Araştırma sonucunda, tüm çalışmaların tek bir ortak etkiyi paylaşmadığı belirlendi. Ayrıca, rastgele etki modeli kullanılarak toplam etki büyüklüğü 0.223 olarak hesaplandı ve z ve p değerlerine göre çalışmanın hipotezi kabul edildi (z = 2.90; p <0.05). Başka bir ifadeyle; "yumurtacı tavuklarda diyet probiyotik takviyesinin yumurta ağırlığı üzerinde önemli bir etkisi vardır".
