Abstract Background The importance of local breeds as genetic reservoirs valuable variation is well established. Pig breeding in Central and South-Eastern Europe has a long tradition that led to the formation several pig breeds. In present study, diversity parameters were analysed six autochthonous from Slovenia, Croatia Serbia (Banija spotted, Black Slavonian, Turopolje pig, Swallow-bellied Mangalitsa, Moravka Krskopolje pig). Animals each these genotyped using microsatellites single...

Genetski uvjetovana stresna osjetljivost svinja jedan je od najpoznatijih problema koji se javlja u proizvodnji i preradi svinjskog mesa. Imajući vidu ekonomsku važnost proizvodnje mesa ova pojava nastoji izbjeći budući da može povećati mortalitet završnoj fazi uslijed razvoja maligne hipertermije te uzrokovati probleme za mesnu industriju zbog loše kvalitete koje manje pogodno tržište ili preradu nepovoljnih fizikalno-kemijskih karakteristika. Cilj ovog rada bio prikazati mehanizam nastanka...

African swine fever (ASF) is a highly contagious viral disease affecting domestic and wild pigs, leading to high mortality rates significant economic losses. Local pig breeds, such as the Black Slavonian pig, are particularly vulnerable due increased contact with boar. This study aimed assess genetic diversity parameters of pigs in Eastern Croatia following recent ASF outbreak using pedigree-based analyses. Pedigree data comprising 13,306 animals were analyzed, reference population 1,658...

Anthropogenic activities and rapidly increasing climate change have led to a significant loss of genetic diversity in domestic animals. Genealogical data traditionally been used monitor diversity. However, due dependency on pedigree completeness errors that can occur genealogical records, inaccurate estimation population parameters, such as the inbreeding coefficient or effective size, might occur. To reduce possible errors, it is necessary combine with molecular data. An integrated approach...

The inclusion of linseed in cattle diets can improve the fatty acid (FA) profile meat, but effects supplementation at different ages have been insufficiently studied. Hence, this study examined and slaughter age on beef carcass meat quality, FA profile, lipid oxidation. Eighty Simmental bulls (initial 221 ± 9 days) were evenly allocated experimental treatments, consisting a control diet linseed-enriched (around 1% whole linseed) fed to until 13 or 17 months age, 2 × factorial design. After...

The Turopolje pig (TP) is a local Croatian breed that almost became extinct in the second half of 20th century. Today, TP still endangered, and new conservation strategy based on products with higher added value needed to preserve breed. There little information quality meat such as smoked dry-cured ham, including impact natural feeds or processing innovations smoke reduction. This study, therefore, investigated effects animal’s diet (either conventionally fed acorn-supplemented) method...

Abstract Improvement of litter size in pigs through selection was considered a difficult task the past. Low heritability, negative correlation between direct additive genetic and maternal effect, limited nucleus population, expression only females, relatively late age measurements, were main reasons for slow improvement. Many environmental factors, as well complex interactions them, influence pigs. The present work describes reviews most important effects influencing size: (1) effects, such...

The aim of the study was to estimate genetic diversity parameters for Banija spotted pig population and apply optimisation methods control inbreeding in three different scenarios. first scenario consisted minimizing by average kinship without considering breeding values. second minimize accounting third traditional optimal contribution selection maximizing value offspring. A total 5 boars 49 sows were selected create mating plan minimise next generation. coefficient 6.97, while effective...

Genetic diversity and breed structure of Banija spotted pig (BS) was analyzed trough 721 pedigree records polymorphism 23 microsatellites on 30 BS pigs. Two phylogenetic trees were constructed from microsatellite information. The inbreeding coefficient obtained by markers 5.6%, while the analysis 3.68%. rate per generation 1.74% effective population size 28.81. In analyses, relationship coefficients genetic distances between individuals calculated using data. Phylogenetic corresponded well...

Banija spotted pig breed was created at the end of 19th century by crossing domestic white sows with drooping ears and/or Turopolje black Berkshire. After a period stagnation in breeding, population is newly recognized only few years ago and currently process valorisation.

Microsatellites (MS) have been, for the last two decades, widely used parentage analysis in all types of livestock, including pigs. Conservation efforts on Banija spotted pigs included genetic characterization breed with MS markers. Since recent comparison pedigree and data revealed some inconsistencies, aim this study was to develop a set highly polymorphic heterozygous markers, which could be prevent errors. 12 markers information content (PIC) above 0.62 were chosen combined into single...

Connectedness between the Landrace pig herds in Croatia was evaluated on field test records (4,930) from 2005 to 2008.

Although population of stable today, this still one endangered breeds that are severely threatened by inbreeding. aim work was to evaluate genetic diversity parameters recent Croatia and consider mating strategies limit increase inbreeding using algorithms within an optimal contribution selection frame. pedigree 1155 individuals analysed. In addition basic structure, following were analysed:...

The mechanisms underlying the domestication process have already been well explained. Starting with Belyaev's pioneering experiment on silver foxes, which showed that selection for tameness (reduced fear response, changes in 'hypothalamic-pituitary-adrenal system'-HPA axis) leads to destabilisation of regulatory systems control morphological and behavioural development, resulting characteristic syndrome. Later, thyroid rhythm hypothesis neural crest cell (NCC) provided additional...
