Comparison of Field and Hatchery Practices in Spray Vaccination Against Infectious Bronchitis

Abstract

In this study, vaccine intake data obtained after the administration of infectious bronchitis vaccine to commercial broiler animals by spray method in hatchery and in the field were compared. Both applications were made using the spray method. In the study, spray infectious bronchitis (IB) vaccine was administered to one of the 2 broiler flocks with an entry capacity of 10,200 and 10,400 at the age of 1 day, and the other at the age of 12 days. Tracheal swabs were taken from the flocks in which both treatments were applied, and RT-PCR analysis was performed on the 4th day following vaccination. Tracheal swab samples were taken on the 5th day from the chicks sent to the farm after the incubation spray application and on the 17th day from the field sprayed herd. RT-PCR analysis was performed from swab samples. The presence of vaccine virus of both groups was compared with one sample t test. According to the findings obtained, the vaccine uptake values obtained after the spray application applied on the 1st day of incubation were statistically significant compared to the traditional field vaccination (p<0.05). Keeping the vaccine intake values of animals at an optimum level has limited success, as vaccine applications in the field contain many variables. In this study, it was determined that animals positioned in a uniform structure in the hatchery were vaccinated with the appropriate dose and technique, and had higher vaccine take rates compared to field vaccinations.

Enfeksiyöz Bronşite Karşı Sprey Aşılamada Saha ve Kuluçkahane Uygulamalarının Karşılaştırılması

Abstract

Bu çalışmada ticari broyler hayvanlara enfeksiyöz bronşit aşısının sprey yöntem ile kuluçkahanede ve sahadaki uygulamasının ardından elde edilen aşı alım verileri kıyaslanmıştır. Her iki uygulama sprey metot kullanılarak yapılmıştır. Çalışmada 10.200 ve 10.400 adet giriş kapasitesine sahip 2 adet broyler sürüsünün birine kuluçkahanede, 1 günlük yaşında, diğerine ise 12 günlük yaşta sprey enfeksiyöz bronşit (IB) aşısı uygulanmıştır. Aşılamayı takip eden 4. gün içerisinde her iki uygulamanın yapıldığı sürülerden trake sürüntüleri alınarak RT-PCR analizi yapılmıştır. Kuluçkahanede sprey uygulaması ardından çiftliğe gönderilen civcivlerden 5.gün ve saha sprey aşı uygulaması yapılan sürüden ise 17. gün trakeal sürüntü örnekleri alınmıştır. Sürüntü örneklerinden RT-PCR analizi yapılmıştır. Her iki grubun aşı virüsü varlığı one sample t testi ile kıyaslanmıştır. Elde edilen bulgulara göre kuluçkahanede 1. gün uygulanan sprey uygulaması sonrasında elde edilen aşı alım değerleri, geleneksel saha aşılamasına göre istatistiksel olarak anlamlı bulunmuştur (p<0.05). Saha aşı uygulamaları birçok değişkeni içinde barındırmaktadır ve hayvanların aşı alım değerlerini optimum düzeyde tutmak sınırlı başarıya sahiptir. Bu çalışmada kuluçkahanede üniform yapıda konumlandırılmış hayvanların uygun doz ve teknik ile aşılanmaları neticesinde saha aşı uygulamalarına göre daha yüksek aşı alım oranlarına sahip olduğu saptandı.
