The fatty acid (FA) composition of milk fat can be positively influenced by the modification of dairy farming and the possible selection of raw material for processing. The question arises as to whether the benefits of a better FA composition will be maintained even after processing dairy products. Thus, the aim was to obtain a more favourable FA composition by a targeted selection of cow’s milk (grazing vs stabled herds) and then compare FAs of milk and fermented product (yoghurt). Bulk tank milk of grazing herds had significantly better FA composition than milk of stabled herds (for example, C16:0 28.07% vs 32.27%,...

This research was carried out to evaluate the pedigree data of the Debrecen White rabbit breed. Pedigree information was supplied by the Debrecen White Rabbit Breeder Association. The final dataset contained all available information on animals registered by the breeding association up to 2023. The reference population was the active breeding stock in 2023. The estimated complete generation equivalent was 7.8, while the mean of maximum generations was 16.29 for the present stock. All individuals within the current population were inbred, with a 5.37% mean inbreeding coefficient. The division of the inbreeding coefficient showed that homozygosity...

Whole-genome sequencing revealed the population structure of Fujian chicken breedsOriginal Paper

Indigenous chicken breeds from Fujian Province, China, exhibit unique and distinctive phenotypic characteristics, including morphology, behaviour, integumentary pigmentation, feather colouration, and production performance. However, the underlying genetic basis governing these specific traits remains unclear. This study aimed to elucidate the population structure of six Fujian local chicken breeds [Bairong chickens (BRCs), Jinhu chickens (JHCs), Minqing chickens (MQCs), Dehua chickens (DHCs), Xiangdong chickens (XDCs), and Hetian chickens (HTCs)] in terms of their genetic resources within the province. The whole-genome resequencing revealed 8 678 612...

Cryopreservation of early-stage male Black Sea trout (Salmo trutta labrax) germ cells and comparison of the whole tissue and enzymatically isolated cellsOriginal Paper

The high plasticity, or the ability to differentiate into various cell types, and capacity to become both gametes of early-stage germ cells (eGCs) allows them to be used for the long-term storage and recovery of genetic information. In this study, species-specific protocols (isolation period, enzymatic separation solution, incubation period, appropriate cryoprotectant, and cryopreservation protocol) were established for the isolation and long-term preservation of Black Sea trout eGCs. In addition, the difference between the application of cryopreservation to the whole gonad tissue and to the enzymatically separated cells has been shown in terms...
