  In my study reveal the situation of the poultry industry. In my research, I used the regularly adopted qualitative method, i.e. the interview. I conversed with the managers of the most important poultry factories, and asked them about the position of the Hungarian poultry sector, the possibility of improving its position, the changes in consumer behaviour, in marketing strategies, means and methods.
  The managers talked about the necessity of collaborating between factories. They agreed on the dominance of commercial chains. In their opinion, these prejudice their chances. They emphasized about the increasing role of processed products and the growing number of sell-stimulated marketing means. The consumer behaviour has changed in the last 10 years too, which helps the market of processed poultry products.

  This paper gives a summary of the possibility for applying genomic information for breeding value estimation in beef cattle breeding. This process is called genomic prediction and is now widely used in dairy cattle globally as well as in some beef and sheep populations. The advantage of genomic prediction is a more accurate estimate of the genetic merit of an individual at a young age thereby facilitating greater annual genetic gain, predominantly through shorter generation intervals. Genomic predictions are more advantageous for sex-linked (e.g., milk yield), low heritability (e.g., fertility) and difficult-to-measure (e.g., feed intake) traits. The larger the reference population, on average, the more accurate the genomic predictions; additionally, the closer genetically the reference population is to the candidate population, the greater the accuracy of genomic predictions. Research is continuing on strategies to generate accurate genomic predictions using a reference population consisting of multiple breeds (and crossbred). Retrospective analysis of real-life data where genomic predictions have been operation for several years clearly shows a benefit of this technology.
