The development of intelligent systems for the tracking of free-range livestock is a challenge to both information and communication technology (ICT) scientists and those in the animal sciences. Cyber-physical systems make it possible to track and control processes involving intelligent objects from the physical and virtual worlds. In the case of free-range grazing, it is necessary to manage processes in two domains ‒ that of the intelligent pasture management and that of the animals. Due to the differences in the conditions of different types of pastures – plain or high land and the characteristics of the cattle breeds, ready-made...

This study compared the efficacy of the egg yolk (EY) and soy lecithin (SL) semen extender during 72-h storage at 4 °C in the presence/absence of streptomycin, penicillin, lincomycin, and spectinomycin. Bull semen samples (n = 12) were obtained and stored in either ANDROMED® (SL extender) or TRILADYL CSS® (EY extender). After 24, 48, and 72 h of storage at 4 °C, bacterial colonies (CFU – colony forming units) were grown and counted on tryptic soy and blood agar, and the bacterial isolates were identified using the MALDI-TOF MS Biotyper. Sperm motility, mitochondrial membrane potential (MMP), membrane...

This study was conducted to investigate the effects and mechanisms of glutamine (Gln) on the repair of acid-induced injury in dairy cow ruminal epithelial cells (RECs) in vitro. Dairy cow RECs were cultured in a medium with pH of 5.5 for 3 h and subsequently treated with various concentrations of Gln (4, 8, 12, 32 mmol/l) for 12 h. The messenger ribonucleic acid (mRNA) expression levels of occludin (OCLN), claudin 1 (CLDN1), toll-like receptor 2 (TLR2), toll-like receptor 4 (TLR4) and genes for inflammatory factors were measured using reverse transcription-quantitative real-time PCR (RT-qPCR)....

The aim of the study was to examine the rabbit consumption habits and opinions of people living in countries that regularly consume rabbit meat. Snowball sampling of data collection was used, a total of 1 860 error-free questionnaires were evaluated. Most of the completed questionnaires came from Hungary, Italy, Spain, China, Poland, France and Mexico. It is to note that 21.3% of respondents have not yet consumed rabbit meat: China (32.1%), Hungary (24.7%), Poland (22.4%), and France (4.8%). The main reasons for not consuming rabbit meat were emotional reasons (22.3%), it does not fit their dietary habits (15.7%). There are 28.7% of respondents...
