Special Issue Information

Dear Colleagues,

Since pigs were domesticated, humans have made lots of efforts in their selection breeding, genetic improvement and better management, mostly to improve production traits such as the growth rate, feed conversion, backfat thickness, proportion of lean meat and number of piglets born. However, there are still a lot of characteristics that need to be improved including piglets’ survivability, resistance to diseases and the longevity of sows. Genetic improvement is attainable by maintaining genetic variation, the use of innovative breeding methods and the maintenance of rare and specialist breeds. Recently, the major focus of pig farming and breeding has been to produce pork of the quality desired by consumers. Moreover, it has become essential to turn attention to new selection goals such as environmental sustainability, animal welfare, and further improving the quality of production and meat quality. Modern pig breeding is evolving as a technology-based industry, making use of advancements in computing, biotechnology and molecular biology. Genetics and genomics have become strategic tools to increase and deepen our knowledge of pigs’ biology.That is why we are pleased to invite you to this Special Issue, established to publish high-quality research papers, review articles, and communications on topics including, but not limited to, the following: reproductive health, ovulation rate, uterine capacity, fertilization, prenatal survival and piglet preweaning survival, litter size, birthweight, variation in birthweight, the maternal behavior and milk production. Important topics may also include sow and boar longevity, libido, semen and sperm quantity and quality. Papers in the areas of pig breeding (crossbreeding, nutrition, welfare), population genetics, and application of classic and molecular methods in improvement of production traits, health, reproduction and meat quality are also welcome.

In Poland, despite a decline in the pig population, pork consumption invariably remains high. For this reason, it is important to search for a potential reduction in pig production costs. One of the feasible solutions is to use sows of hybrid lines. Currently, several sow lines are available on the Polish market, such as CG36 (Choice Genetics). The aim of this study was to determine the level of reproduction performance in this line considering the effect of parity and farrowing season. Additionally, coefficients of phenotypic correlations between analysed reproduction performance parameters were determined. The experimental material comprised 112 females inseminated with semen of a boar of the Excelium line (Choice Genetics), which produced 336 litters. The investigated population was characterised by a high level of reproduction traits and young age at first farrowing (AFF), while the number of piglets born alive (NBA), the number of piglets weaned per litter (NW), and the number of piglets weaned per sow per year (PWSY) reached high, economically advantageous levels. Primiparous sows produced and reared lower numbers of piglets than multiparous sows, which indicates the need to maintain an adequate herd structure, with a maximum share of gilts at 30%. No effect of the season on values of reproduction traits was found, which shows optimal environmental conditions in the animal housing where the pigs were kept. Dependencies between the analysed traits confirmed the results reported by other authors, where NBA was highly positively correlated with LW, although LW increased with an increase in NBA. No correlations were found between PWSY and the other traits. In turn, the observed coefficients of phenotypic correlations indicate that in order to reduce AFF in CG36 sows, it is necessary to control FI. Full article

The present work aimed to estimate the usefulness and effectiveness of selected physicochemical indicators in the evaluation of meat quality as well as culinary and processing value using a simple and canonical phenotypic correlation method. Studies were carried out in 495 porkers. The most relationships were obtained for the adenosine triphosphate (ATP) breakdown indicator (R1), electrical conductivity (EC) and glycolytic potential (GP) with meat quality traits that are non-diagnostic criteria, i.e., lipids and protein content, water holding capacity (WHC), technological yield (TY), drip loss (DL) and meat tenderness (MT). The results of this study indicate that about 62% of the variability in meat quality is the result of the initial level of glycogen in muscle tissue. The strong relationship between EC2 and pH24 (acidity of the muscle tissue at 24 h after slaughter) parameters and a wide spectrum of traits of meat quality (sets covering the parameters of the culinary and processing quality of meat and indicating the volume of drip loss), as well as with the pH1 and R1 criteria confirms the possibility to perform a quick and cheap ‘on line’ classification of qualitative meat properties in meat processing plants.

The purpose of this paper is to summarize the available important information on local pig breeds maintained in Europe. Genetic erosion has prompted national and international bodies to take organized action aimed at the minimization of further losses of biodiversity. Since the genetic resources of livestock ensure both food security and the sustainable development of rural areas, genetic diversity is indispensable for sufficient flexibility of future animal husbandry to adapt to changing consumer demands and climatic conditions. Therefore, the problem of biodiversity has recently become an essential part of the comprehensive international program of the World Conservation Strategy and the global idea of the so-called sustainable development. The issue of biodiversity protection occupies an important place in the provisions of the EU Common Agricultural Policy. The successive financial perspectives assume an increase in relevant expenditure from the EU and national budgets. With regard to the protection of native pig breeds, a particularly large increase in funding was recorded in 2014–2020. Full article
