“…Recently, functional traits such as reproductive and health characteristics have been more focused on biological, economic and ethical causes and also because of animal welfare concerns. The profitability of dairy cattle depends not only on the production of milk but also on non-production traits such as fertility and health (Toghiani, 2012;Dahiya et al, 2020). Today's production efficiency in farm animals has become the primary concern of breeders in the livestock industry.…”

Objective: The aim of this study is to determine genetic correlations between linear type traits, yield characteristics and first lactation profitability for use in selection programs. Material and Methods: The research was carried out in Hatay province between 2012-2017. A total of 810 cows in the first lactation were used in the study. Analysis of variance and covariances of genetic parameters was carried out with Multivariate Limited Maximum Likelihood test. Results: The average first lactation net profit, 305-d milk yield, first calving age, conception rate at first service, and calving ease rate were determined as 540 US$, 6008 kg, 793 d, 61.6%, and 91.7%, respectively. Heritabilities of linear type and production traits ranged from 0.10 to 0.42 and 0.04 to 0.39, respectively. The genetic correlations between first lactation profitability and type traits ranged from -0.08 and 0.42, while between first lactation profitability and production traits ranged from 0.06 and 0.34. The highest genetic correlation was between first lactation profitability and central ligament (0.42), while the lowest genetic correlation was between first lactation profitability and udder depth (-0.08). The highest genetic correlation was between first lactation profitability and lactation protein yield (0.34), while the lowest genetic correlation was between first lactation profitability and conception rate at first service (0.09). Genetic correlations between type and production traits varied from -0.42 (FA and CFS) to 0.49 . Conclusion: These results showed that primiparous cows having more angular, strong fore udder attachments, strong foot and legs structure were more profitable and opportunities of selection programs by using genetic correlations between linear type traits and production characteristics. It also concluded that the first lactation profitability could be used successfully in Turkish dairy cattle breeding programs. ÖZAmaç: Bu çalışmanın amacı, ıslah programlarında kullanılmak üzere doğrusal tip özellikleri, verim özellikleri ve birinci laktasyon karlılığı arasındaki genetik korelasyonların tespitini yapmaktır. Materyal ve Metot: Araştırma 2012-2017 yılları arasında Hatay ilinde yürütülmüştür. Araştırmada toplam 810 baş birinci laktasyonda olan inek kullanılmıştır. Genetik parametrelerinin varyans ve kovaryanslarının analizi ise Multivariate Limited Maximum Likelihood testi ile gerçekleştirilmiştir. Bulgular: Ortalama inek başına birinci laktasyon net kar, 305-gün süt verimi, ilk buzağılama yaşı, ilk tohumlamada gebe kalma oranı ve kolay doğum oranı 540 US$, 6008 kg, 793 gün, %61.6 ve %91.7 olarak belirlenmiştir. Doğrusal tip özellikleri ile verim özelliklerinin kalıtım dereceleri sırasıyla; 0.10-0.42 ve 0.04-0.39 arasında tahmin edilmiştir. Birinci laktasyon karlılığı ile doğrusal tip özellikleri arasındaki genetik korelasyonlar -0.08 ve 0.42 arasında, birinci laktasyon karlılığı ile verim özellikleri arasındaki korelasyonlar 0.06 ve 0.34. arasında tahmin edilmiştir. Birinci laktasyon karlılığı ile en yüksek korelas...

“…Thus, genetic links between routine observations carried out by appraisers during the evaluation process can be used to validate the classifications from individual appraisers [31,32]. In general, udder central ligament, teat length, udder (in general), and teat placement receive different scores that relate to milk production ability in several cattle breeds [31,33,34].…”

The traditional point of view regarding dairy cattle selection has been challenged by recent genomic studies indicating that livestock productivity prediction can be redefined based on the evaluation of genomic and phenotypic data. Several studies that included different genomic-derived traits only indicated that interactions among them or even with conventional phenotypic evaluation criteria require further elucidation. Unfortunately, certain genomic and phenotypic-derived traits have been shown to be secondary factors influencing dairy production. Thus, these factors, as well as evaluation criteria, need to be defined. Owing to the variety of genomic and phenotypic udder-derived traits which may affect the modern dairy cow functionality and conformation, a definition of currently important traits in the broad sense is indicated. This is essential for cattle productivity and dairy sustainability. The main objective of the present review is to elucidate the possible relationships among genomic and phenotypic udder evaluation characteristics to define the most relevant traits related to selection for function and conformation in dairy cattle. This review aims to examine the potential impact of various udder-related evaluation criteria on dairy cattle productivity and explore how to mitigate the adverse effects of compromised udder conformation and functionality. Specifically, we will consider the implications for udder health, welfare, longevity, and production-derived traits. Subsequently, we will address several concerns covering the application of genomic and phenotypic evaluation criteria with emphasis on udder-related traits in dairy cattle selection as well as its evolution from origins to the present and future prospects.
