“…The fact that the birth weight averages of the BB genotypes were found to be high in both studies indicates that the B allele positively affects the growth characteristics of cattle. However, Pytlewski et al (2018), reported that AA homozygotes of the Pit-1 gene are characterized by the biggest calf weight. A cow's body weight is an important factor that can affect her milk and reproductive production.…”

“…They observed insignificant effects of Pit-1 gene polymorphism on milk yield and its composition in Brown Swiss cattle (Aytekin and Boztepe, 2013). In association studies on Angus, Limousine, and some other beef cattle, significant associations were reported between Pit-1 polymorphic structures and birth weight and weaning weight (Dybus et al, 2003;Xue et al, 2006;Pytlewski et al, 2018). While other researchers reported Pit-1 polymorphic structures, they stated that there was no significant relationship between the gene and meat yield characteristics (Di Stasio et al, 2002;Zhao et al, 2004;Curi et al, 2006).…”

“…Because of these functions, the Pit-1 gene may be considered as a candidate gene for increasing milk production and regulating growth and development in farm animals (Zhang et al, 2009;Heidari et al, 2012). Pit-1 acts on PRL and GH, and since these hormones are also necessary for mammary gland development and milk production (Peel and Bauman, 1987;Pytlewski et al, 2018;Thuy et al, 2018), genetic variation of the Pit-1 gene may be associated with yield traits and can be considered as a marker.…”

Abstract. The aim of this study was to examine the polymorphic structures of Pit-1 and CSN3 genes of Holstein calves bred in Gümüşhane province of Türkiye, to determine the distribution of genotype and allele gene frequencies, as well as examine the effects of determined polymorphisms on birth weight of calves. HinfI polymorphisms of Pit-1 and CSN3 genes were identified in DNA isolated from blood samples of 100 Holstein calves used in the study, using the PCR-RFLP method. According to the Hardy–Weinberg genetic equilibrium test, it was observed that the distribution of genotype frequencies of HinfI polymorphisms of Pit-1 genes in the studied population was in equilibrium, but not in equilibrium in terms of CSN3 gene location. The AA, AB, and BB genotype frequencies of the Pit-1 gene in the population were 13.4 %, 40.2 %, and 46.3 %, respectively; the frequency of the A allele was 0.34, while for B allele it was 0.66. The AA, AB, and BB genotype frequencies of the CSN3 gene were found to be 24.5 %, 36.7 %, and 38.8 %, respectively; the frequency of the A allele was 0.43 and the frequency of the B allele was 0.57. According to the Hardy–Weinberg genetic equilibrium test, the distribution of genotype frequencies was in equilibrium in the Pit-1/HinfI polymorphism, but not in the CSN3/HinfI polymorphism. A statistically significant relationship was not found between the genotypes of both polymorphic regions and calf birth weight.

“…Studies investigating the association of POU1F1 gene polymorphisms have not only focused on milk yield but also on growth and reproductive traits in various cattle breeds. Specifically, research on Polish Black-and-White Holstein-Friesian and Limousine cattle and calves has found that Pit-1 gene polymorphisms are associated with body weight, age at sexual maturity, and reproductive parameters such as insemination index (Pytlewski et al, 2018;Pytlewski et al, 2022). However, studies on Pit-1/HinfI polymorphisms and growth parameters have yielded mixed results, with some studies reporting no association with birth weight in calves, growth in Black Anatolian cattle, and growth and reproductive parameters in Canchim cattle (Grossi et al, 2015;Fındık and Özdemir, 2022;Sakar and Zülkadir, 2022).…”

As the global population grows, there is a need to produce higher yields in food, agriculture, and livestock. To achieve this, scientists are exploring new techniques and methods. However, it is crucial to select the right candidate genes and markers, especially in techniques like QTL and MAS in livestock, to ensure success. We conducted a study to determine allele frequencies and their association with milk yield in 70 Simmental cattle breeds in two lactations using the PCR-RFLP technique. The statistical analysis was conducted using the general linear model procedure with the least square method The study focused on the allele frequencies for the POU1F1-HinfI gene in Simmental cattle. The dominant B allele frequency for POU1F1/Hinf1 was 0.58, while the A allele frequency was 0.42. Simmental population was under HardyWeinberg Equilibrium (HWE) for the POU1F1-HinfI genotypes (p>0.05) The study found that genotype frequencies were in balance for POU1F1/Hinf1. No significant correlation between POU1F1-HinfI gene polymorphisms and milk yield was found, but they have been associated with growth and reproductive traits in various cattle breeds. The results could provide useful information for breeding programs aimed at improving the performance traits of Simmental cattle.
