Ewes' reproductive performance could be predicted using the data available early in their life. Ewe birth rank, dam birth rank, first litter size, and first lambing interval are significantly associated with ewe reproductive performance up to the fourth year of life. Precise prediction of ewe reproductive performance using the early predictors is impossible due to the low R² predicted. The value of the lower threshold of the 95 % prediction interval might be useful in making selection decisions.

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 results of this study found that a mutation site of the MLPH gene was associated with the white-feather phenotype of quail, which provided a theoretical basis for the study of quail feather color change and quail reproduction.

The addition of 1 mL kg⁻¹ pomegranate seed oil (PSO) to feeds improved performance. The addition of PSO had a positive effect on shelf life, and it increased punicic acid and conjugated linoleic acid (CLA) levels without reducing egg quality.

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.

The application of antibiotics is being regulated continuously. Therefore, natural agents are being investigated that aim to strengthen the defense system of poultry. In our study, capsanthin was applied to investigate its effect on immune response under lipopolysaccharide immunization. Based on our results, capsanthin decreased the levels of pro-inflammatory cytokines at both mRNA and protein levels, which suggest the positive effects of capsanthin during inflammation in broiler chickens.
