Global Research Trends and Future Perspectives on the Repeat Breeder Syndrome

Abstract

In cattle farming enterprises, reproductive efficiency is one of the most important factors that determine the income level of enterprises by directly affecting milk production and the number of calves born. One of the reasons for low productivity in dairy farming is repeat breeder cows. In this study, worldwide trends in repeat breeder were analyzed bibliometrically. The aim of the research is to analyze the trends and groups by examining the publications in this field. In the searches made with the keyword “repeat breeder” in the Web of Science (WOS) database between 1980-2025, 1746 studies were examined, inappropriate studies were eliminated and 1713 articles were analyzed. Data collection was based on information including the title, author names, year of publication, journal name, and citation count. VOSviewer software was used for the analysis, with accuracy ensured by applying text mining and visualization techniques (e.g., bubble maps). The results show that there are 1713 articles in the field of repeat breeder with 37419 citations and an average of 22 citations per article. The number of published articles and corresponding citations has grown since 2002. Most articles (72%) were published in the fields of agriculture and veterinary medicine, with the USA, India, and China accounting for the highest number of publications (45%). The majority of the studies (92%) are indexed in the SCI-Expanded category. This study highlights global trends and important studies in the field of repeat breeders and provides guidance on future research directions in this field.

Repeat Breeder Sendromu Üzerine Küresel Araştırma Eğilimleri ve Gelecek Perspektifleri

Abstract

Sığır yetiştiriciliği işletmelerinde üreme etkinliği, süt üretimini ve doğan buzağı sayısını doğrudan etkileyerek işletmelerin gelir düzeyini belirleyen en önemli faktörlerden biridir. Süt sığırcılığında verim düşüklüğünün nedenlerinden biri de döl tutmayan (repeat breeder) ineklerdir. Bu çalışmada, repeat breeder ile ilgili dünya çapındaki eğilimler bibliyometrik olarak analiz edilmiştir. Araştırmanın amacı, bu alandaki yayınları inceleyerek eğilimleri ve grupları analiz etmektir. Web of Science (WOS) veri tabanında 1980-2025 yılları arasında “repeat breeder” anahtar kelimesiyle yapılan aramalarda 1746 çalışma incelenmiş, uygun olmayan çalışmalar elenerek 1713 makale analiz edilmiştir. Veri toplama için başlık, yazar isimleri, yayın yılı, dergi adı ve atıf sayısını içeren bilgilere dayanmaktadır. Analiz için VOSviewer yazılımı kullanılmış olup, doğruluk metin madenciliği ve görselleştirme teknikleri (örneğin, kabarcık haritaları) uygulanarak sağlanmıştır. Sonuçlar, repeat breeder konusunda 37419 atıf ve makale başına ortalama 22 atıf ile 1713 makale olduğunu göstermektedir. Yayımlanan makale sayısı ve buna karşılık gelen atıflar 2002'den bu yana artmıştır. Makalelerin çoğu (%72) tarım ve veterinerlik alanlarında yayınlanmış olup, en yüksek yayın sayısı ABD, Hindistan ve Çin'e aittir (%45). Çalışmaların çoğu (%92) SCI-Expanded kategorisinde indekslenmektedir. Bu çalışma, repeat breeder konusundaki küresel eğilimleri ve önemli çalışmaları vurgulamakta ve bu alandaki gelecekteki araştırma yönleri konusunda rehberlik sağlamaktadır.
