Autochthonous cattle breeds represent important resources of genetic diversity. The Busha cattle breed is reared in the Balkan Peninsula and is characterised by high adaptability, resilience, longevity, small body size, and low maintenance and production requirements. During the 36-year observation period, the total population of the autochthonous Busha cattle breed in the Republic of Croatia amounted to 10 411 animals. Pedigree completeness for the total population, considering the first parental generation, was 97.1%. The average inbreeding coefficient was 2.44%, ranging from zero to 42.6%, while the average relatedness coefficient was 3.56%...

Our study investigated the genetic variability of specific foot and claw disorders, namely dermatitis digitalis, sole ulcer, and three broader categories (infectious diseases, claw horn lesions, and general claw disorder) in Czech Holstein cows. We also examined their genetic relationships with clinical mastitis and key fertility traits. Using both linear and threshold animal models, we concluded that heritability estimates for foot and claw disorders were consistently higher when employing the threshold model. A significant finding was the genetic correlation between sole ulcer and dermatitis digitalis, which ranged from 0.21 (calving...

The domestication process has had a substantial and varied impact on animals in terms of anatomy, physiology, and behaviour. Poultry species are particularly important for humans, with the most significant being chickens, geese, and ducks. However, it is not well understood whether, or to what extent selection influences the eggshell structure compared to wild ancestors. In the present study, we compared eggshells from three species: Red junglefowl and its four domesticated forms: Green-legged partridge, Lohmann Brown, Ko-Shamo, meat type breeder (Cobb 500); Greylag goose, and two domesticated breeds: Bilgoraj goose and White Koluda goose, as well...
