Summary: In the livestock industry, the mortality rate of young animals is an important factor for farm efficiency and societal concerns. Genetic variation plays a role in survival rate, and appropriate genetic selection can help alleviate the pressure of mortality. However, survival rate is a dynamic indicator affected by various factors. Piglet survival depends on the genetic makeup of the individual piglet, the mother pig, and the nursing sow. Clear genetic variation exists in piglet survival, and genetic selection can increase their survival rate. However, it is important to balance this selection with other production traits.

Summary: The use of genetic selection in livestock has improved the sustainability of animal farming. Geneticists have selected for sows with larger litters, reducing feed requirements per piglet produced. To enhance piglet survival, genetic selection for increased sow teat number is suggested. However, more data are needed to confirm associations between sow teat traits and piglet weaning traits.

Summary: Piglet mortality from farrowing to weaning is a major concern in outdoor organic production systems. This study suggests that selection focusing on sow genotype, the use of younger sows, and crossbreeding could contribute to reducing piglet mortality in this production system.

Summary: This study used computer vision to automatically predict sow activity and investigated how sow behavior influences piglet's performance. By analyzing video images and using clustering analysis, groups of sows with similar activity patterns were identified. The results showed that sow behavior on D-1 and during the period D1-D7 had significant effects on piglet survival and growth.

Summary: The SWine IMputation (SWIM) haplotype reference panel and web server provide a valuable resource for improving imputation and genetic discoveries in pigs. By developing a reference haplotype panel based on 2259 whole genome-sequenced animals representing 44 pig breeds, this study overcomes the limitation of low density genotyped variant sites, resulting in improved genetic mapping resolution. The use of this resource for genotype imputation demonstrates significant improvements in genetic mapping resolution.

Summary: During the composting of ASFV-infected swine carcasses, the infectious ASFV was rapidly eliminated by day 5, coinciding with a temperature increase in the compost pile to >= 55 degrees C. Although ASFV DNA remained detectable in all swine tissues and some carbon samples, positive detection of ASFV DNA did not correlate with virus infectivity.

Summary: This study examined the relationship between the anti-inflammatory action of dexamethasone treatment on primiparous sows and their piglets' performance in the first 5 days of life. The results showed that dexamethasone treatment before farrowing onset could reduce the duration of farrowing and the need for obstetric intervention, but had no effect on piglet weight gain and survival rates.

Summary: This study aims to evaluate the impact of different concentrations (3%, 6%, or 9%) of dimethylacetamide (DMA) as a cryoprotectant on post-thawed sperm quality, motility, antioxidant-biomarkers, and the expression of anti-freeze related genes. The results showed that 3% DMA group maintained higher post-thawed sperm quality compared to the other tested groups, with improvements in motility, viability, and antioxidant enzyme activity. Additionally, certain anti-freeze related genes were upregulated in the 3% DMA group.

Summary: The frequency of semen collection and the season have a significant impact on the quality of rooster semen and its suitability for cryopreservation. This study found that semen collection frequency did not affect semen quality, but it was influenced by the season. Three times per week semen collection can be conducted without compromising semen quality in Thai native roosters. However, sperm concentration was negatively affected during the rainy season, while the highest sperm production occurred in the winter.

Summary: This paper discusses the decreasing viability of neonatal piglets with the increase in the number of piglets born per sow per year; emphasizes the importance of early intervention and management strategies in improving piglet survival rates; and introduces some management strategies for identifying low-viability piglets and increasing their survival rates.

Summary: Research shows that supplementing sows with HMB can increase total litter weight at birth, promote piglet growth, and increase the concentration of IgM in colostrum. Additionally, HMB has positive effects on average piglet weight and growth rate.

Summary: Soy lecithin (SL) and its nanoparticles (nano-SL) can effectively prevent spermatozoa cryodamage during cryopreservation, with a concentration of 1.0% nano-SL showing the most positive impact on post-thawing semen quality and fertility in roosters. The addition of nano-SL reduced oxidative stress levels, improved sperm motility and mitochondrial activity, and enhanced fertility and hatchability in rooster semen after artificial insemination.

Summary: The study found significant environmental influences on the loin depth, backfat depth, and carcass growth of crossbred pigs, with genetic control of heat tolerance and genotype by environment interaction detected. The impact of heat stress and genotype by environment interaction varied across traits, with backfat depth showing higher heritability under comfortable conditions. The study highlights the importance of genetic resilience and performance under changing environmental conditions in swine.

Summary: This study evaluates the impact of genetic and non-genetic factors on the conception rate of frozen semen bulls. The findings suggest that management factors have a greater influence on conception rate compared to genetic factors. The fertility-related information obtained from this study, based on data from different villages in India, is valuable for decision-making in breeding policies.
