The hatchability is one of the key factors affecting the supply of market chicks and economic benefits, and it is significantly influenced by the eggshell thickness. The aim of this study was to develop a genotyping method for SNP of ovocleidin-116 in commercial native chicken and layer by using real-time PCR technology labeled with kompetitive allele-specific polymerase chain reaction (KASP). Commercial red feather native chicken, silkie, and Lohmann layers were randomly sampled for DNA extraction and genotyping with 50 birds per breed. Preliminary results indicated that the allelic frequency of cytosine in commercial red feather native chicken, silkie, and Lohmann layers were 0.85, 0.2, and 1, respectively. The effect of OC-116-C1336G on eggshell thickness and hatchability will be further investigated to confirm the essential influence.

The EXOC4 genetic marker is one of the candidate markers for pig litter size traits. The purpose of this study was to screen the EXOC4 genotypes of stock pigs in breeding farms to understand the frequency of favorable genotypes or alleles indicated in the literature and to further evaluate the markers for industrial applicability. DNA samples were collected from 942 pigs of 9 breeding farms, including 371 Duroc, 414 Landrace, and 157 Yorkshire. The analysis results show that the percentages of CC, CT and TT genotypes in all tested pigs were 66.35, 28.13 and 5.52%, respectively﹔ the CC, CT, and TT genotype percentages of individual breeds of Duroc, Landrace, and Yorkshire pigs are 50.67, 38.54, 10.78% vs. 70.53, 27.05, 2.42% vs. 92.36, 6.37, 1.27%,
respectively. Analyzing the genotypes of 109 sows with litter size traits, the percentages of CC, CT, and TT genotypes were 77.06, 18.35, and 4.59% respectively. In addition, preliminary analysis of the association between genotypes and litter size traits shows that the Duroc and Landrace sows with CT genotype had higher mean litter size than CC and TT ones. However, this part still needs to continue to collect, analyze, and verify data on litter size traits in order to evaluate the applicability of EXOC4 as a breeding marker for pigs.

Uniformity of body weight is a very important management tool and an important economic trait in chicken industry. In order to explore the impact of the body weight of breeding roosters on the uniformity of the marketing body weight of their offspring, this study used the 16-week-old body weights of 266 breeder chickens of the G14 generation and 2,017 growing chickens of the G15 generation of four inbred lines of Taiwan native chicken Taizhu No. 1 to conduct uniformity analysis. The 16-week-old body weight of male and female chickens of each line was divided into high- weight group, medium-weight group (M) and low-weight group. We analyze the 16-week-old body weight of the offspring between the medium body weight group and all breeding roosters group (AL), and compare their coefficients of variation. The results showed that there were significant differences in the coefficient of variation of body weight at 16 weeks of age between the comparison groups of breeding roosters (P < 0.05). The offspring of breeding roosters in group M have a lower coefficient of variation than the offspring of roosters in group AL, reflecting better uniformity. The results obtained in this study can be used as a reference for chicken breeders to select breeding roosters for producing broiler chicks.

Intramuscular fat (IMF) content is one of the key factors affecting pork tenderness, juiciness, odor, and flavor. The literature indicated that GPATl (Glycerol-3-phosphate acyltransferase l) and PRKAG3 (protein kinase AMP-activated non-catalytic subunit gamma 3) genes significantly affect the IMF content and pH value of the longissimus dorsi muscle in pig. This study aims to develop a genotyping method in pig breeds using real-time PCR technology. Thirteen Duroc, thirteen Landrace, eight Yorkshire, and thirteen black pigs were randomly sampled for genotyping. Preliminary results showed that the CC genotype frequencies of the above breeds at the GPATl- SfaNI site were 3l, l00, l00, and 62%, respectively﹔ the GPATl-BbvI site were 39, 39, 63 and l00%, respectively. However, the AA genotype frequencies for PRKAG3-A325G were 46, 23, 75, and 23%, respectively. In the future, we will further analyze the correlation between the above GPATl and PRKAG3 gene mutations and the IMF content of pig longissimus dorsi muscle to clarify their impact.

Climate change is a global issue. Increased ambient temperatures will intensify the challenges of raising animal in tropical and subtropical areas. Heat stress have a negative impact on boar fertility. This experiment collected the semen of Duroc boars auctioned by the Formosan Farmers Association for Swine Improvement from 2014 to 2015. Samples were divided into 4 group by March-May (spring), June-August (summer), September-November (autumn) and December- February (winter) and evaluated the effect of season on semen quality traits such as volume, motility, concentration, total sperm number, viability, acrosome and sperm membrane integrity, mitochondria depolarization and sperm chromosome structural integrity. The results showed that the semen concentration of Duroc boars in spring and winter were significantly higher than that in summer and autumn (P < 0.05). The total sperm number in spring and winter were significantly higher than in autumn (P < 0.05). The proportion of sperm mitochondria depolarization in autumn was higher than in spring (P < 0.05). The sperm chromatin structure integrity in autumn was lower than in spring (P
< 0.05). It shows that the semen quality in autumn was worse than in spring. The semen quality of Duroc boars are affected by season. In order to cope with climate change, semen evaluation indicators in hot seasons can be considered selection of boars for heat tolerance in the future.

0evelopment of tissue-engineered vascular grafts (TEVGs) using pluripotent stem cells holds significant potential for treating human cardiovascular diseases. However, current research involving the use of porcine induced pluripotent stem cells (piPSCs) to construct TEVGs is still at the attempt stage, and the technology requires further development for preclinical studies. Here, we report the generation of smooth muscle cells (SMCs) derived from piPSCs and the utilization of a 30 mold to autonomously assemble SMCs into a flexible tubular structure, which can be used to create small-sized TEVGs through multiple layering. This technique can construct TEVGs without scaffolds. To fulfill their application potential, further validation through in vivo transplantation studies in animal models after strengthening the structure is required.

Lanyu pigs are a miniature swine breed used extensively in Taiwan for biomedical research, such as in the fields of basic research, cardiovascular diseases, tissue engineering, and pharmacology. They hold significant potential for understanding and treating human diseases. However, the understanding of the anatomical structures of Lanyu pigs is limited. Furthermore, the lack of anatomical atlases and biomedical imaging data hampers precise and effective procedures during animal research. Here, male and female Lanyu pigs are subjected to magnetic resonance imaging (MRI) of the brains, abdominal fat, and reproductive organs, and to computed tomography (CT) of whole bodies. This comprehensive biomedical imaging database consists of sequential cross- sections that can be reconstructed into 30 structures. The imaging allows for real-time review on a computer, promoting precise and efficient procedures during animal research and reducing the number of animals used. This database will be available online in the future, offering substantial benefits for experimental research and educational purposes.

This experiment aimed to explore the effects of increasing incubation temperature in the early and late stages on chick quality and mortality. 300 fertilized broiler eggs were used and randomly divided into 4 groups according to egg weight. Group A had a fixed temperature of 37.8°C as a control﹔ Group B and C raised the incubation temperature to 39.5°C for 6 hours a day on days 4 to 7 and 15 to 18 after hatching, respectively﹔ Group D combined the treatments of Groups B and C. The results showed that the egg weight loss ratio of groups B and D was significantly higher than the control group and group C after 7 days of incubation. The incubation periods of groups B, C, and D were significantly shorter than the control group. The total hatchability of each group was similar﹔ however, the mortality in group C was higher in the late incubation period, while the mortality in group D during the middle incubation period was significantly higher and lower in the late period. There was no significant difference in chick body weight between groups, but the body temperature of group D was significantly lower than others. In summary, raising the incubation temperature at different incubation periods had no effect on the body weight of the chicks. However, if the incubation temperature was increased in both the early and late stages, the chicks would have a lower body temperature, which could be used as a reference for subsequent research on the regulation of chicken body temperature under temperature changes.

The application of artificial reproductive technologies aims to improve the economic benefits of livestock. Among these technological applications, in vitro embryo production (IVEP) has attracted attention, and its application in the livestock industry continues to increase. The number of bovine embryo transfers worldwide has increased tenfold in the past decade (200,000 to 2 million / year), of which live egg collection combined with in vitro embryo production (OPU-IVP) accounts for the majority (reaching more than 68% in 2022), which has become The key research and development direction is to improve the efficiency of cattle breeding and increase unit output. The purpose of this study is to evaluate the effectiveness of Ovum Pick Up in collecting oocytes from dairy cows. The ovaries are fixed in the rectal veterinary examination method and the eggs in the ovarian follicles are aspirated using an ultrasonic imaging probe combined with an egg collection probe. In this way the operation process requires skilled skills to achieve a recovery rate of more than 60%. The surface- coated egg retrieval probe can effectively improve the development effect on the ultrasonic display screen, and can increase the recovery rate by an average of 7% compared with traditional probes.

Damage to boar sperm from cryopreservation is known to result in reduced motility, viability and litter size. Novel sperm function assays were used to detect poor quality frozen porcine semen prior to use and thus improve AI success. The purpose of this study was using novel sperm function assessment to characterize cryopreserved boar spermatozoa. Low freezability boar showed about 37.0% (P < 0.05) motility decrease, 22.1% (P < 0.05) progressive motility decrease, 24.0% (P < 0.05) sperm viability decrease and 8.3 % (P < 0.05) acrosome integrity decrease, 1.9% intact DNA decrease and 2% of oxidative stress increased after frozen-thawed were observed. In summary, freezable ejaculates assessment and sperm selection before starting the cryopreservation process will benefit the artificial insemination with frozen-thawed boar sperm products and can provide reasonable fertility outcomes.
