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.

This study's aim is to investigate the polymorphism of Simmental cattle raised on a private farm in terms of the CSN3 gene locus from milk proteins by using the PCR-RFLP method and to reveal the distribution of genotype and allele frequencies of animals in terms of related gene locations. In addition, the relationship between genotypes and some performance characteristics is investigated.

The effects of slaughter age and muscle type on meat quality properties of Eastern Anatolian Red (EAR) bulls (n = 46) were investigated in the present study. Forty-six EAR bulls were slaughtered at 15, 17, 19, 25, and 27 months. Meat samples were taken from longissimus dorsi (LD) and gluteus medius (GM) muscles obtained from the carcasses 24 h post-mortem.

The team that prepared this article developed and patented electrical teat dipping (ETD) to prevent cow mastitis. ETD was developed by combining teat dipping application and an electrical field stimulation technique on teats. In this study, it was aimed to determine the effects of ETD on clinical mastitis incidence and bulk tank milk somatic cell counts on dairy farms. Based on our findings, we conclude that the effects of ETD on mastitis rates reduction are very positive.

The aim of this paper was to evaluate semen parameters from Czech Fleckvieh bulls used in artificial insemination (AI) in the Fleckvieh population. We analyzed 1029 samples from 46 Fleckvieh bulls from one AI station. Semen from the bulls was collected once a week, which is not usual in other AI stations. We also assessed sperm quality parameters of ejaculate before freezing and after thawing. The ejaculate parameters were evaluated in relation to the collection season and the age of the bulls.

We evaluated the effects of supplementing cattle feed with difructose anhydride III (DFA III) by measuring urinary sterigmatocystin (STC) concentrations. DFA III was supplemented for 2 weeks to 10 animals, and non-treated animals served as controls. Our findings demonstrate the effect of DFA III on reducing the urinary concentration of STC in Japanese Black cattle.

For local breeds kept in small herds, consideration of classical herd effects implies imprecise genetic evaluations. In consequence, the present study aimed to evaluate different herd clustering strategies, considering social–ecological and herd characteristics. The similarities of herds within created herd clusters and improved reliabilities of estimated breeding values suggest the application of herd clusters in statistical models for genetic evaluations in local breeds.

The objective was to find whether cow growth, milk performance, and behaviour are affected by rearing conditions until weaning after a milk-fed period of 84 d. Holstein heifers were assigned to one of three treatments: SM, pen with mother to 21st day, then group pen; SN, with own mother, then in pen with nursing cow; H, in hutch from 2nd to 56th day. The SN group tended to have the highest production of milk for 305 d and crossed the maze the fastest.

Bovine cumulus–oocyte complexes were cultured in a three-step system imitating estradiol-17β (E2) and progesterone (P4) concentrations in preovulatory follicular fluid for in vitro maturation (IVM). The blastocyst formation rate after E2- and P4-imitated IVM was significantly higher than that after the other IVM (control, E2-imitated, P4-imitated), suggesting that the three-step IVM system with the preovulatory levels of E2 and P4 improves the developmental potential of embryos in vitro.

Intramammary infections in dairy cows lead to considerable economic losses for farmers. A new somatic cell count index (SCCI) was proposed for the accurate prediction of milk yield losses caused by elevated somatic cell count (SCC). Depending on the time of SCC elevation, parity, milk production level, and level of average SCC, the estimated milk yield loss from the phenotypic potential of milk yield was at least 0.8–0.9 kg day−1 for primiparous cows and 1.3–4.3 kg day−1 for multiparous cows.

This study aimed to determine the effect of cow breed, season and type of diet on the fatty acid profile of raw milk. The study was conducted on bulk milk samples collected in winter and summer from 4 herds of Czech Fleckvieh and 4 herds of Holstein cows. One half of the herds was grazed while the other half was not. Effect of breed was found in odd-chain, branch-chain and hypercholesterolemic FA while season and type of diet mainly influenced the proportion of saturated and polyunsaturated FA.

The aim of the study was to determine the impacts of different levels of mycotoxin load of dairy herds on the milk indicators. During three subsequent years, samples of feedstuffs and individual milk were collected from four herds of Czech Fleckvieh and from four herds of Holstein cows. The most frequently occurring mycotoxins were fumonisins, deoxynivalenol, and zearalenone. Changes were noted in some milk indicators such as fat, acetone, pH, electric conductivity, alcohol stability, or curd quality.

Our studies evaluated the effects of parity and season on pregnancy rates of repeat-breeder (RB) Japanese black beef cattle after embryo transfer. Our findings indicate that the parity of the recipients does not have an apparent effect on the pregnancy rates following the transfer of fresh and frozen embryos. However, season may affect reproductive performance in RB multiparous cows.

Short summary
The meta-analysis demonstrated that the relationships of major milk protein genes with other factors should be examined using the codominant genetic model in general. According to results of the meta-analysis, relationships among some CSN3 genotypes and fat yield, fat content, and protein content, and relationships among some BLG genotypes and daily milk yield, fat content, protein yield, and protein content were found statistically significant (p < 0.05).
The meta-analysis demonstrated that the relationships of major milk protein genes with other...
