Summary: The study revealed differences in vaginal microbiota between sows with varying risk for POP during late gestation, as well as differences within sows that subsequently experienced POP. Furthermore, differences in vaginal microbiota were observed between sows scored PS1 at gestation week 12 and those scored PS1 or PS3 at gestation week 15.

Summary: In Poland, pork consumption remains high despite a decline in the pig population. One potential solution to reduce pig production costs is to use sows of hybrid lines. This study aimed to investigate the reproductive performance of CG36 sows in relation to parity and farrowing season. The results showed that the investigated population had high levels of reproduction traits and young age at first farrowing. The number of piglets born alive, number of piglets weaned per litter, and number of piglets weaned per sow per year reached economically advantageous levels. There was no effect of farrowing season on reproduction traits, indicating optimal environmental conditions in the animal housing. The study also found correlations between certain reproduction traits, suggesting the need to control certain factors to reduce age at first farrowing in CG36 sows.

Summary: Efficient food production and good animal welfare are of utmost importance in current times. Parturition in pigs is a critical process that affects piglet outcomes and sow health, leading to economic loss and welfare concerns. However, there is no consensus on the prevalence of dystocia in pigs and how to identify it. Understanding the parturition process and influencing factors is crucial for the early identification of dystocia and the development of best practices.

Summary: The experiment aimed to evaluate the efficacy of NSAID and SAID for improving farrowing house performance of sows, but found that administering meloxicam to older sows reduced the number of live piglets born. While both NSAID and SAID improved feed intake, there was no significant improvement in piglet growth or postnatal mortality.

Summary: Abortion in sows can result in significant financial losses and can be caused by both maternal and fetal factors, including factors related to pregnancy control and infections. Risk factors for abortion include inappropriate temperature, seasonal effects, stress, and toxic substances. Diagnosis and prevention of abortion require consideration of multiple factors, including clinical evaluation, pathogen detection, and proper management practices.

Summary: Animal production, particularly pork production, is influenced by environmental factors and climate change, impacting feed production and nutrient cycles. This study assessed daily feed intake of sows and associated greenhouse gas emissions, finding that different production scenarios led to varying levels of CO2 emissions per kilogram of piglet. Improving production efficiency in animal farming, especially in relation to environmental impact, is crucial for sustainable practices.

Summary: This study focused on exploring sow lactation performance, estimating the heritability of litter weight gain (LWG) as an indicator for milk production ability, and identifying seven significant SNPs related to milk production in Yorkshire pigs. Further analysis revealed potential candidate genes involved in lactose metabolism, colostrum immunity, milk protein, and milk fat, providing valuable insights into improving milk production in pigs.

Summary: This study establishes a swine model system to evaluate the protective effects of maternal vaccination-induced immunity against influenza virus infection in pregnant sows and neonatal piglets. The results demonstrate that the candidate vaccine can induce robust immune responses in pregnant sows and passively transferred to newborn piglets. This study provides valuable insights into the impact of vaccination on maternal immunity and fetal/neonatal development.

Summary: This study found that adding yeast extract (YE) to sow diets can increase feed intake, reduce body weight loss during lactation, and positively impact nucleotide concentrations in milk, potentially promoting piglet growth. Furthermore, YE can enhance antioxidant capacity in both sows and piglets.

Summary: The aim of this study was to estimate the genetic parameters of elk hunting traits in the Finnish Jamthund population. Phenotype and pedigree data were used, and a repeatability animal model was applied to estimate the genetic parameters. Weather, trial factors, and dog characteristics were considered in the models. The heritability estimates were generally low, with the highest estimate seen in the searching behavior.

Summary: The study aimed to detect pigs in need of medical treatment or extra management by monitoring changes in feeding behavior patterns. A machine-learning algorithm was used to predict the health status of pigs based on one-day, three-day, and seven-day features. The model based on the seven-day window showed the best results, achieving an 80% AUC. In conclusion, feeding behavior-based features demonstrated good sensitivity and specificity in predicting sickness, but the precision of the method was low.

Summary: Genomic selection has been utilized in dairy cattle breeding to predict breeding values accurately and increase genetic gain. However, there is a concern that genetic diversity may decrease due to increased inbreeding rate and decreased effective population size. This research aimed to estimate the impact of genomic selection on inbreeding rate and effective population size using both pedigree and genomic data.

Summary: In this study, the effect of enriched carnosine synthesis on metabolomic profiles and biochemical compounds in slow-growing Korat chicken jejunum tissue was investigated. It was found that significant changes in the concentrations of metabolites were detected between different experimental groups. Furthermore, supplementation of beta-alanine and L-histidine precursors in the diet showed a correlation with specific biochemical compounds. These findings help to understand the relationships and patterns between the spectral and metabolic processes related to carnosine synthesis.
