This study aims to investigate the screening of leptin genetic polymorphism and its effect on lameness prevalence. Prevalence of lameness was evaluated and results showed that genotypes and other factors included in the logistic regression model significantly affect the prevalence of lameness in Holstein cows (P < 0.01). The probability of lameness incidence varied between 37 % and 99 % with parity. This recorded incidence is greater in winter and autumn than in the summer and spring.

The lactation curve and lactation survival are important in dairy cattle breeding. Their simultaneous improvement results in economic benefits. The genetic relationship between the lactation survival and the lactation curve shape traits of milk yield and fat and protein percentages using information from of 25 981 primiparous Tunisian Holsteins was investigated. Cows that had higher persistencies for fat and protein percentages were more likely not to survive.

Short summary
Genetic parameters for 11 456 Tunisian Holstein cows were estimated for the following five reproductive traits: calving interval (CI), calving to first service interval, calving to conception interval (CCI), first service to conception interval and number of services per conception. Low heritabilities were estimated for these traits, and genetic correlation estimates between them were moderately high. The CCI–CI genetic correlation was 0.85, indicating that they are the same trait genetically.

Polyunsaturated fatty acids play an important role in a wide variety of physiological processes. They are produced by a series of chemical reactions. One of the enzymes converting such acids is a delta 6 desaturase encoded by the FADS2 gene. Therefore, we aimed to determine possible associations between the polymorphism in this gene and milk fatty acid composition in dairy cattle. An identified substitution could be used as a potential genetic marker for fatty acid composition in bovine milk.

Resequencing of diversity hidden in the innate-immunity genes of the TLR series in Czech Simmental, its conserved subpopulation, and the ancestral Czech Red cattle showed sufficient potential for infection resistance breeding regardless of the prevailing breeding for production traits on the one hand and a limited potential of diversity preserved in the historical populations on the other. The importance of the characterization of genetic resources to counteract changing infections is implied.

Four indels were identified by sequencing with DNA pool. Association analysis showed that three of them were associated with growth traits (P<0.05). Our results demonstrated that the polymorphisms in bovine MSRB3 gene were significantly associated with growth traits, which could be candidate loci for marker-assisted selection (MAS) in cattle breeding. These molecular markers are expected to accelerate the process of molecular breeding.

Most gene mtDNA 16S rRNA studies were with aquatic organisms, insects, and a few mammalian species; no reports involved cattle. The objective of this research was to characterize the genetic and phylogenetic diversity among 12 cattle breeds utilizing gene mtDNA 16S rRNA. The base percentages of this gene had a strong bias towards A + T. Only transitions or transversions were detected. The phylogenetic analysis indicated the existence of Bos taurus and Bos indicus ancestry in Chinese cattle.

The study was to clarify the roles of ACSL5 in regulating synthesis of triglycerides and lipid droplet formation in bovine preadipocytes through vectors constructing and electransfection. Research results confirmed that the ACSL5 gene could promote the synthesis of triglycerides in bovine adipocytes by participating in the fatty acid metabolism pathway. The interaction of ACSL5 with related fatty acid synthase in the fatty acid biosynthesis pathway needs further analysis.

We used lots of Chinese cattle to detect the specific regional variation in the IGF1R genome. It was found that this variation in the Chinese cattle population is related to the weight and height of the cattle. There is a lot of genetic information in this mutated region, which may be the cause affecting the traits. Our study provided a preliminary result for the functional role of the IGF1R variation in larger populations and for an important marker in cattle breeding programs.

ASIP can regulate the obesity of mice but studies of ASIP effects on bovine fat deposition and meat quality are rare. The L1-BT element inserted upstream of bovine ASIP can cause ASIP mRNA overexpression. In this study, L1-BT element indel, two single nucleide polymorphisms (SNPs) in ASIP, and its haplotypes showed significant correlations with fat deposition traits and fatty acid composition in Chinese Simmental steers, suggesting that ASIP may be a biomarker for beef cattle breeding selection.

An extensive genetic evaluation of cattle fattening performance was performed in this study. Fifteen SNPs in the LEP, FABP4, DGAT1, TG, IGF1, IGF1R, MYF5, LGB, CAPN1, CAST, GHR, and OLR1 genes were evaluated in 296 purebred Holstein–Friesian bulls using PCR-RFLP. This study clearly demonstrated that individual or combined effects of the genotypes at the selected genes may be effective on performance traits at different periods of animal growth and fattening.

Genetic markers are important tools for beef cattle breeding. Our work suggests that CAPN1 genetic markers have a positive effect on meat tenderness and marbling traits, the most important meat quality traits for consumers. The associations between the genotyped SNPs in this research and meat quality traits are of potential interest to the beef industry and could lay an important foundation for the expanding panel of functional variation relevant to meat quality.

Effects of miRNA polymorphisms on phenotypic traits have been studied in several species but much less in cattle. We tested the association between polymorphisms of bta-miR-2313 and growth and carcass traits in the Slovenian Simmental cattle breed and developed an atlas of miRNA regulatory elements. Bta-miR-2313 warrants further functional analysis since it overlaps with several QTL, has over 3100 predicted targets, and is located within GRAMD1B, associated with production traits in cattle.

ACADSB is a member of the acyl-CoA dehydrogenase family, which can catalyze the dehydrogenation of acyl-CoA derivatives in lipometabolism. Our previous transcriptome analysis results identified it as a differentially expressed gene in mammary tissue between low and high milk fat cattle. Current results showed that ACADSB expression level was positively correlated with cellular triglycerides content, and it was actively involved in fatty acid metabolism pathway in BME cell of dairy cattle.

The androgen receptor (AR) plays the vital role of a bridge on the function of the androgen and has sexual size dimorphism. For this reason, the objective of this study was to explore the novel indel variants within the cattle AR gene and to detect a novel 24 bp indel within the AR gene. It significantly affected growth traits, suggesting that this indel may be a useful DNA marker for the elimination or selection of excellent individuals for cattle breeding.

This work identified SNPs in the growth- and development-related ATBF1 gene in cattle. Five novel SNPs were found in 644 cattle. The results found that SNP1, SNP2, and SNP3 and the combined genotypes SNP1–SNP3, SNP1–SNP4 and SNP2–SNP5 were significantly associated with growth traits in Qinchuan and Jinnan cattle. These findings indicate that the bovine ATBF1 gene has marked effects on growth traits, and the growth-trait-related loci can be used as DNA markers for MAS breeding programs in cattle.

Bovine mastitis, a prevalent and complex infectious disease, can result in significant dairy cattle losses. MicroRNAs (miRNAs) play important roles in regulating innate and adaptive immune responses. The results in this paper show that the expression of miR-144-5p and miR-130b-5p in mastitis-infected mammary tissue was significantly downregulated and upregulated, respectively, compared to healthy tissue. Our findings may provide a method for the treatment of mastitis.

The main contribution of our paper is the identification of several SNPs of the SIRT1 gene in beef cattle and their relationships to carcass traits such as weight and meat percentage. We believe that this contribution is theoretically and practically relevant because beef cattle are bred to maximize carcass quality, but traits that lead to carcass quality are difficult to assess in vivo. We provide a method to select individuals for breeding based on genetic propensity for meat production.

Prosaposin (PSAP) is involved in muscle development and as a candidate gene in economic traits of cattle. Six novel SNPs of PSAP were identified and 47 traits in beef cattle measured. Association analysis revealed I10-65G > A, I10-162C > T, and E11-93C > G were significantly associated with carcass composition traits. Individuals with GCCCGC and ACCTCC haplotypes showed higher dressed weight, backfat thickness, and rib eye area, thus suggesting a genetic influence on cattle carcass composition.

Genetic polymorphims in the growth hormone (GH) gene were studied in 410 Holstein dairy cows. Genotyping was carried out using PCR-RFLP. Data were analyzed by the MIXED procedure to reveal the effect of GH genotypes on reproductive traits. GH-AluI had a favorable effect on exanimate traits except for the age at the first calving. The homozygous LL genotype seemed to be advantageous for calving interval and days open. A significant effect of different GH-AluI–MspI combined genotypes was found.
