“…The level of recent inbreeding in Charolais and Limousin populations was in sound with Mastrangelo et al [79]. The obtained estimates of recent inbreeding in Slovak Spotted and Slovak Pinzgau populations correspond to the pedigree estimates found by Kadlečík et al [80] and Kadlečík et al [81], respectively. The other three estimates (F GRM , F HOM , and F UNI ) of inbreeding indicated a non-significant effect of relatives mating on the genome of analysed populations.…”

This study aimed to assess the level of biodiversity in selected local cattle populations as important food resources in Slovakia. The biodiversity level was derived from the genome-wide data collected for dairy (Jersey), dual-purpose (Slovak Pinzgau, Slovak Spotted), and beef breeds (Charolais, Limousine). The commonly used indices, genomic inbreeding (FROH, FGRM, FHOM, FUNI) and effective population size (NeLD), were used to quantify the impact of relatives mating on the genome of analysed populations. Even if the low NeLD estimates signalise significant loss of genetic variability within populations, the genomic inbreeding under 1% (except Jersey) showed that the intensity of diversity loss is not so rapid and can be managed by the re-arrangement of long-term breeding strategies. The analysis of genetic differentiation degree across populations assumed that the specialisation of breeds during their grading-up led to the specific nucleotide changes, especially in genes responsible for preferred phenotypic traits. The breed-specific differences observed mainly in the genome of Charolais (carcass traits) and Jersey (milk production traits) populations resulted from the polymorphisms in CAPN1 (μ-calpain) and CSN1S2 (casein alpha s2) genes, respectively. Obtained results confirmed that the specific haplotypes are strongly associated with the genetic nature of breed depending on production type.

“…The Slovak Spotted cattle is an important dual-purpose breed with a long farming tradition in Slovakia. It is mainly due to its excellent dairy as well as beef production (Strapák, 2004;Bujko et al, 2011;Strapák et al, 2013;Kasarda et al, 2015;Kadlečík et al, 2017), and belongs to the Simmental type of cattle.…”

The study aimed to examine the analyses of the trend in the numbers of dairy cows, production and reproductive traits in the population the Slovak Spotted cattle for period 2010 to 2019. The number of Slovak Spotted dairy cows is maintained on a relatively stable level in recent years. There was a decrease in the number of animals (12 428 in 2010), but not as strong as after 1990 (85 518). From 2017 number of animals is rising from 14,062, to 14,150 (2018) and 14,627 (2019), respectively. As compared to 2010 an increase of 13.15% in 2017, 13.86% and 17.68%, in 2018 and 2019 respectively was observed. Population size raised from 113.15% (2017) to 117.68% in 2019 respectively. The average annual increase in milk production between the years 2010 to 2019 was + 157.5 kg of milk (total 1,575 kg of milk), + 5.8 kg of fat (total 58 kg of fat) and + 6.1 kg of protein (total 61 kg of protein). Positive growth of milk production in recent years is slightly comparable with the trend of breeding improvement.

“…As shown in many studies of wild as well as domestic species, the decrease of population size is mostly accompanied by the significant loss of genetic diversity. That is important for ensuring the adaptive potential of species and preventing the occurrence of inbreeding depression over a long time period (Kadlečík et al, 2016).…”

The aim of this study was to evaluate the state of genetic diversity in population of Barbary lion based on the genealogical analysis. Currently, this lion subspecies does not occur in the wild, and its population is considered to be critically endangered. The pedigree file consisted of 545 animals, while the reference population included 445 individuals. Alongside pedigree completeness, the parameters derived from common ancestor were used to analyse the state of genetic diversity in target population. The completeness of pedigree data had significantly decreasing tendency with increasing generations. The pedigree completeness index was the highest in the first generation (68%). The average value of the inbreeding coefficient was very similar in the reference population and the pedigree file (F = 0.05). Across generations, the trend of inbreeding increase was positive mainly due to the long-term use of specific lines and families for mating. The relative high average relatedness among individuals (AR = 0.06) only reflected the individual increase in inbreeding (3.18%). As expected the higher level of individual increase in inbreeding was found in the pedigree file (3.41%). The effective population size at level 26.66 confirmed that the Barbary lion is critically endangered by the loss of diversity. Because of this, the future continuous monitoring of genetic diversity of this subspecies is necessary, especially for long-term conservation purposes.
