It's important that we investigate the CNV of GAL3ST1 gene and process the association between the results of Q-PCR and growth characteristics of Chinese cattle. The study revealed that GAL3ST1 gene expression in various tissues was high in intestine and low in liver tissue, as shown by the results. In a word, we speculated that the GAL3ST1 gene would be used as a molecular marker, but this report revealed that it does not have a CNV of cattle that could be used for molecular breeding of cattle in China.

Based on previous research, we predict that CLCN2 may be a candidate gene involved in cell volume control, transepithelial transport, and cell proliferation. This research was designed to investigate CNVs in the CLCN2 gene and determine its relationship with growth characteristics in four Chinese cattle breeds. The CNV2 mutation in the XN cattle race had a significant effect on body slanting length, chest girth, and body mass. The correlation of CLCN2 gene CNV1 and CNV2 in the YL cattle and cannon circumference was significant. The CNV1 and CNV2 in CLCN2 are correlated with growth traits in two distinct cattle populations and could be used as candidate markers for cattle molecular breeding.

This research was carried out to determine the genotype and allele frequencies, as well as some physical characteristics in Simmental and Brown Swiss breed cattle raised in Turkey's province of Erzurum, Turkey. The leptin/Sau3AI gene in the population, with 88,7% for AB and 1,6% with BB genotypes were determined in Brown Swiss cattle, with genotype AA, 78,3% with AB, 16,7% with AB, and 5,0% with 5,0% BB genotypes were determined. The A allele frequency in the Simmental cattle was 0,87 and B allele was 0,13, while B allele frequencies were 0,13 in the Simmental cattle, and A allele was 0,97 and B allele was 0,06 in the Brown Swiss breed. According to a Hardy-Weinberg genetic balance test, the population of the Brown Swiss breed was balanced, but not in the Simmental breed.
