This study aims to present a more systematic and developmental research direction by classifying animal-medication-related research trends published in Korea. We analyzed the research trends of 68 domestic animal-medication programs published in 26 journals over the past 24 years under the premise of the necessity of animal-medication therapy, which is considered a very effective intervention method in the practice areas of various subjects. Therefore, this study examines the year of publication of animal-medication-related research conducted in various academic fields from 1998 to 2022, research data sources, characteristics of research subjects, types of interventions and research topics, research design and intervention sessions, intervention methods, and ethical consideration statements. The results of this study are as follows: First, in the source of research and research trends by year, the number of papers published in animal-related societies was the highest at 34 (50%); the number of studies has been steadily increasing since the mid-2000s. Second, regarding research trends by subject, 45 (66%) were general subjects, 23 (34%) were medically diagnosed, 60 (88%) were selected through pre-evaluation, and 8 (12%) were requested. Third, regarding research trends by method, 27 (40%) of the pretests were conducted before and after the experiment-control group, and only 3 (4%) of the 68 papers were examined later. Fourth, regarding research trends by content, depression (25%) was the most frequently applied variable, and regarding intervention sessions, 53 (78%) were less than 12 sessions. Fifth, regarding research trends and ethical consideration statements by treatment approach method, 58 cases (85%) of individual treatment approaches and 10 cases (15%) of intervention approaches integrated with individual treatment approaches, and 23 cases (34%) of studies with ethical consideration statements or the Institutional Review Board’s (IRB) approval. Based on the study results, the implications and research directions of animal-assisted therapy-related research are discussed.

Lactococcus taiwanensis starin K_LL001 was isolated from the gut of grasshopper (Oxya chinensis sinuosa). In this study, we presented the complete genome sequence of L. taiwanensis stain K_LL001. The genome of K_LL001 genome was composed of 1 circular chromosome without plasmids. The length of the whole genome was 2,018,259bp, guanin + cytosine (G±C) content (%) was 38.75%, with 2,021 predicted protein-coding sequences (CDS). The most abundant CAZyme class in L. taiwanensis strain K_LL001 was glycoside hydrolases (GH) class. GHs is the key enzymes involved in carbohydrate metabolism, and they catalyze the hydrolysis of glycosidic bonds in complex carbohydrates such as cellulose, hemicellulose, and starch. Moreover, L. taiwanensis strain K_LL001 has genes encoding enzymes which can catalyze the transformation of one glycoside to another. Overall, this study will contribute to a further understanding of L. taiwanensis strain K_LL001 at the genomic level and provide a theoretical basis for its future application in swine industry.

Interest and investment in cultivated meat are increasing because of the realization that it can effectively supply sufficient food resources and reduce the use of livestock. Nevertheless, accurate information on the specific technologies used for cultivated meat production and the characteristics of cultivated meat is lacking. Authorization for the use of cultivated meat is already underway in the United States, Singapore, and Israel, and other major countries are also expected to approve cultivated meat as food once the details of the intricate process of producing cultivated meat, which encompasses stages such as cell proliferation, differentiation, maturation, and assembly, is thoroughly established. The development and standardization of mass production processes and safety evaluations must precede the industrialization and use of cultivated meat as food. However, the technology for the industrialization of cultivated meat is still in its nascent stage, and the mass production process has not yet been established. The mass production process of cultivated meat may not be easy to disclose because it is related to the interests of several companies or research teams. However, the overall research flow shows that equipment development for mass production and cell acquisition, proliferation, and differentiation, as well as for three-dimensional production supports and bioreactors have not yet been completed. Therefore, additional research on the mass production process and safety of cultivated meat is essential. The consumer’s trust in the cultivated meat products and production technologies recently disclosed by some companies should also be analyzed and considered for guiding future developments in this industry. Furthermore, close monitoring by academia and the government will be necessary to identify fraud in the cultivated meat industry.

The present study aimed to find out the feasibility of increasing the meat quality of finishing gilts by increasing their slaughter weight (SW) to an extra-high (XH) level and also by using a low-lysine (lys) diet in XH-weight pig production. Twenty-four gilts and eights barrows were divided into four treatments (T) by gender, SW, and diet: T1 [barrow; 116-kg SW; Medium (Med)-lys (0.80%) diet], T2 [gilt; 116-kg SW; Med-lys], T3 [gilt; XH (150 kg) SW; Med-lys], and T4 [gilt; XH SW, Low-lys (0.60%)]. Growth performance from 85 kg of body weight to SW was measured only for T3 and T4. All animals were slaughtered at their target SW, followed by physicochemical analyses and sensory evaluation on the Longissimus lumborum muscle (LL). Average daily gain did not differ between T3 and T4. Dressing percentage was greater for T3 vs. T2. Backfat thickness was greater for T1 vs. T2 and T3 vs. T2, not being different between T3 and T4. The LL pH was lower and Warner-Bratzler Shear force value was greater for T3 vs. T2. Other physicochemical measurements including the intramuscular fat content were not different or different narrowly if different at all (p < 0.05) between T3 and T2 or T4, but not between T1 and T2. The percentages of major fatty acids including 16:0, 18:0, 18:1, and 18:2 in LL, which did not differ between T2 and T3, differed between T3 and T4 apparently resulting from a difference in composition of the ingredients of the two diets. The sensory texture score was greater for T3 vs. T2 in fresh LL; in cooked LL, juiciness and umami scores were greater for T3 vs. T2, flavor score being less for T4 vs. T3. The gender effects on physicochemical and sensory pork quality were small, if any. Overall, the meat quality of finishing gilts could be improved by increasing the SW to the XH level, but not by using the Low-lys diet, suggesting that it will be feasible to produce XH-weight market gilts if the increased meat quality can make up for the expected decrease in production efficiency accompanying the increased SW.

Hanwoo and Jeju Black cattle (Jeju Black) are native breeds of Korean cattle. Jeju Black cattle are recognized as natural monuments and are known to exhibit slower growth rates compared to Hanwoo. While several studies have analyzed the genetic characteristics of these cattle, there has been limited research on the differences in their microbiome. In this study, rumen fluid was obtained from three Hanwoo steers and three Jeju Black steers, and three different diets (total mixed rations [TMRs] for growing, early fattening, and late fattening periods) were used as substrates for in vitro fermentation. The in vitro incubation was conducted for 3 h and 24 h following a 2 × 3 factorial arrangement. After both incubation periods, fermentation characteristics were analyzed, and ruminal microbiome analysis was performed using 16S rRNA gene sequencing, employing both QIIME2 and PICRUSt2. The results revealed significant differences in the ruminal microbiota due to the inoculum effect. At the phylum level, Patescibacteria and Synergistota were found to be enriched in the Jeju Black inoculum-treated group. Additionally, using different inocula also affected the relative abundance of major taxa, including Ruminococcus, Pseudoramibacter, Ruminococcaceae CAG-352, and the [Eubacterium] ruminantium group. These microbial differences induced by the inoculum may have originated from varying levels of domestication between the two subspecies of donor animals, which mainly influenced the fermentation and microbiome features in the early incubation stages, although this was only partially offset afterward. Furthermore, predicted commission numbers of microbial enzymes, some of which are involved in the biosynthesis of secondary metabolites, fatty acids, and alpha amylase, differed based on the inoculum effect. However, these differences may account for only a small proportion of the overall metabolic pathway. Conversely, diets were found to affect protein biosynthesis and its related metabolism, which showed differential abundance in the growing diet and were potentially linked to the growth-promoting effects in beef cattle during the growing period. In conclusion, this study demonstrated that using different inocula significantly affected in vitro fermentation characteristics and microbiome features, mainly in the early stages of incubation, with some effects persisting up to 24 h of incubation.

The objective of this study was to identify genomic regions and candidate genes associated with productive traits using a total of 37,099 productive records and 6,683 SNP data obtained from five Great-Grand-Parents (GGP) farms in Landrace. The estimated of heritabilities for days to 105kg (AGE), average daily gain (ADG), backfat thickness (BF), and eye muscle area (EMA) were 0.49, 0.49, 0.56, and 0.23, respectively. We identified a genetic window that explained 2.05-2.34% for each trait of the total genetic variance. We observed a clear partitioning of the four traits into two groups, and the most significant genomic region for AGE and ADG were located on the SSC 1, while BF and EMA were located on SSC 2. We conducted Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG), which revealed results in three biological processes, four cellular component, three molecular function, and six KEGG pathway. Significant SNPs can be used as markers for quantitative trait loci (QTL) investigation and genomic selection (GS) for productive traits in Landrace pig.

This study investigated the correlation between piglet performance and sow body weight change (BWC) during two gestational periods: 35-70, 70-105, and 35-105 days. A cohort of 70 sows was evaluated for body weight change (BWC), backfat thickness change (BFC), caliper score change (CALC), feed intake, and weaning-to-estrus interval (WEI). The collected data were then analyzed according to the two specified periods. Our findings highlighted that piglet birth weight, weaning weight, and average daily weight gain (ADG) correlated with sow body characteristics, including BFC and CALC. The strongest correlation was observed with BWC. Piglet mortality was intimately associated with BFC. Piglet birth weight, weaning weight, and ADG showed a positive correlation with sow BWC, particularly during the 35-70 day period. Furthermore, sows displaying a higher BWC during the 70-105 day period, and also exhibiting a higher BW gain from 35-70 days, registered greater piglet weight gains and higher weaning weights. These trends became more apparent as the sow

The objective of this experiment was to evaluate the physiochemical characteristics of three tertiary hybrids (crossbreeds) of pigs, with and without coffee supplementation. A total of fifty pigs of different mixed breeds Landrace × Yorkshire × Duroc (LYD), Yorkshire × Berkshire (YB), and Yorkshire × Woori (YW); 113.45 kg ±3.33 kg) at age 190 days old were employed to measure the effect of spent coffee grounds from Gangneung-Si area of South Korea on the meat quality of pigs in the pigsty at the Kangwon National University Teaching and Research Farm using the 2 × 2 factorial arrangements. Our result shows that the fat percentage was higher (P<0.05) in YB and YW. pH was higher (p<0.05) in the YB breed. Meat colour a* was higher (p<0.05) in the YB and YW breeds. Meat colour b* was higher (p<0.05) in YW. Water holding capacity was higher (p<0.05) in the YB and YW breeds. Drip loss 6 was lower (p<0.05) in YB and YW. Cooking loss was higher (p<0.05) in LYD and YW breeds. The fatty acid components such as linolenic (C18:2), myristic (C14:0), and palmitoleic (C16:1) were higher (p<0.05) in the YB. Palmitic (C16:0), stearic (C18:0), and arachidic (C20:0) was higher (p<0.05) in YW. Lignoceric (C24:0) was higher (p<0.05) in LYD and YW. Unsaturated fatty acid (UFA) was higher (p<0.05) in YB and YW, while Polyunsaturated fatty acid (PUFA) was higher (p<0.05) in YB. Monosaturated fatty acid (MUFA) / PUFA was higher (p<0.05) in LYD. Saturated fatty acid (SFA) was higher (p<0.05) in YW. UFA and MUFA were higher (p<0.05) in the YB. MUFA / PUFA were higher (p=0.05) in YB. We concluded from our results that YW and YB had close meat qualities in terms of firmness and flavour compared to LYD as the physiochemical characteristics of meat were improved. SCG supplemented at 0.5% had no detrimental effect on the parameters measured.

The Enterococcus faecium (E. faecium) strain AK_C_05 was isolated from cheonggukjang, the Korean traditional food, collected from a local market in South Korea. In this report, we presented the complete genome sequence of E. faecium strain AK_C_05. The genome of E. faecium strain AK_C_05 genome consisted of one circular chromosome (2,691,319 bp) with a guanine + cytosine (GC) content of 38.3% and one circular plasmid (177,732 bp) with a guanine + cytosine (GC) content of 35.48%. The Annotation results revealed 2,827 protein-coding sequences (CDSs), 18 rRNAs, and 68 tRNA genes. It possesses genes, which encodes enzymes such as alpha-galactosidase (EC 3.2.1.22), beta-glucosidase (EC 3.2.1.21) and alpha-L-arabinofuranosidase (EC 3.2.1.55) enabling efficient utilization of carbohydrates. Based on Clusters of Orthologous Groups analysis, E. faecium strain AK_C_05 showed specialization in carbohydrate transport and metabolism indicating the ability to generate energy using a variety of carbohydrates.

Incorporating organic acids into cattle feed should be carefully considered because dietary organic acids may affect voluntary feed intake and rumen fermentation. We conducted a feeding trial for the practical evaluation of grain vinegar. Lactating Holstein cows (n = 19) were divided into two groups, then were subjected to each of two treatments in a crossover design. The rumen fermentation parameters, blood urea nitrogen and NEFA, milk composition, and milk fatty acid content were analyzed. No notable changes were observed in rumen fermentation parameters or blood metabolites. Corn silage intake, milk production, and 4% FCM were not affected by vinegar supplementation. The proportions of fatty acids in milk originating from de novo synthesis in the mammary gland were 25.2% and 25.4% in control and vinegar-fed groups, respectively. The levels of branched-chain fatty acids iso-C14:0, iso-C15:0, and iso-C16:0 were substantially decreased by vinegar supplementation, are known to be related to rumen environmental stress. This study showed that feeding grain vinegar to lactating dairy cows had no effect on feed intake, rumen fermentation, or milk production, although the proportion of some branched-chain fatty acids in the milk decreased.
