With a history tracing back to at least the 18th century and a substantial global influence on various breeds, Polish Arabian horse population is of paramount importance for both breeders and conservationists. However, its genetic makeup and the population dynamics are still not well understood. This study presents an analysis of the modern Polish...
Arabian show horses are well known for their exceptional beauty and elegance. The breed type, body conformation and movement are assessed during horse shows by licensed judges. The five judging categories are type, head and neck, body and topline, legs and movement, which are scored on a 20 point scale. It can be hypothesized that the scores in dif...
The Commission on Genetic Resources for Food and Agriculture, was initially established by FAO, in 1983, to address plant genetic resources (PGR). It became the primary permanent international forum for governments to discuss, negotiate and decide on matters specifically relevant to genetic resources for food and agriculture (GRFA). Over time, the...

Sustainability in animal breeding can be understood as continuous availability of breeding animals and their germinal products for commercial production, that now and in the future, meet the requirements of a broad range of stakeholders: breeders, farmers, livestock keepers, producers, consumers and others, while respecting animal welfare and promo...
The domestication of the horse began about 5500 years ago in the Eurasian steppes. In the following millennia horses spread across the ancient world, and their role in transportation and warfare affected every ancient culture. Ownership of horses became an indicator of wealth and social status. The importance of horses led to a growing interest in...

Horse racing serves as a performance test to evaluate the speed and endurance of horses. Globally, the breed most widely used for racing is the Thoroughbred. In Poland, the Purebred Arabian horse racing sector size is comparable to that of Thoroughbreds, as the racing merit is a crucial element of the complex Polish breeding goal for Arabian horses...
The European Regional Focal Point for Animal Genetic Resources (ERFP), is the European regional platform of National Coordinators (NCs) supporting management of animal genetic resources (AnGR). To assess the performance of the ERFP platform/network and consider options for its further development, a survey was performed among NCs. Twenty-five NCs r...
Native breeds of farm animals, despite their unique characteristics and adaptability to diverse and often adverse environmental conditions, are at risk due to their lower profitability and corresponding declining use. According to FAO data, there are currently around 8800 livestock breeds in the world ( http://www.fao.org/dad-is/en/ update: 09.11.2...
Two mutations affecting the ovulation rate and litter size are segregating in Olkuska sheep population, FecX O in the BMP15 gene, and the G7 site mutation in GDF9 gene. Homozygous carriers of both mutations are hyperprolific, contrary to the sterility observed in homozygous carriers of most other BMP15 and GDF9 mutations. The objective of this stud...
Highly pathogenic avian influenza (HPAI) poses a huge threat to poultry production and also introduces an epidemiological risk in the human population. Thus far, HPAI has been controlled mainly through widespread implementation of biosecurity, and in the case of an outbreak, liquidation of flocks and establishment of protection zones. Alternative s...

The aim of this study was to assess the level of genetic variability in the Olkuska sheep population and evaluate inbreeding effects on birth weight, weaning weight (at 56 days of age), lamb survival up to 56 days and the litter size of ewes. Pedigree information over a 36 year period of Olku...
The study aimed to identify important factors threatening genetic diversity within small sheep populations, and to propose sustainable management strategies. Demographic evolution, genetic diversity and current genetic management practices were analyzed in a population of Polish Olkuska sheep. Unbalanced contributions of individual rams to the next...
Due to the competition with high yielding international dairy breeds, many local cattle breeds that traditionally supplied the European dairy market are being marginalised and thus increasingly endangered. While there are many options to enhance profitability of dairy utilisation of local dual purpose cattle breeds, in some of them, for various rea...
The aim of this study was to conduct genetic analysis of 219 cold-blooded Sztumski mares, which were enrolled in the genetic resources conservation programme in 2008. The inbreeding level in the mares, their average genetic relationship with the population, and the average coefficient of kinship were analysed, as well as the number and origin of co...
Some sheep breeds are naturally prolific, and they are very informative for the studies of reproductive genetics and physiology. Major genes increasing litter size (LS) and ovulation rate (OR) were suspected in the French Grivette and the Polish Olkuska sheep populations, respectively. To identify genetic variants responsible for the highly prolifi...

The need to provide policy-makers with succinct, yet informative, messages is widespread in biodiversity management, and has led to the development of various “indicators” that can serve this purpose. While global data on the status of animal genetic resources for food and agriculture (AnGR) have been made available in a number of publications, the...
The degree to which a breed is exposed to becoming extinct, i.e. its degree of endangerment (DE), is an essential information to orient conservation policies. Assessing DE properly is a difficult task, as numerous factors are involved. Several methods are currently used in Europe and the paper first discusses the development of some objective crite...
Recent discoveries that high prolificacy in sheep carrying the Booroola gene (FecB) is the result of a mutation in the BMPIB receptor and high prolificacy in Inverdale sheep (FecX(I)) is the result of a mutation in the BMP15 oocyte-derived growth factor gene have allowed direct marker tests to be developed for FecB and FecX(I). These tests were car...
