This study aimed to investigate the effects of dietary Ptecticus tenebrifer on the fecal microbiomes of bichon frise. A total of 16 bichon frise dogs (average weight, 2 kg) were randomly allotted to 4 dietary treatments (4 dogs/group): general pet food, two types of domestic pet food containing Ptecticus tenebrifer, and one imported pet food containing Ptecticus tenebrifer. In the controls, Firmicutes accounted for the highest proportion (82%) at the phylum level in the fecal microbiomes. The Tax4Fun2's functional prediction program indicated that the control groups showed a relatively high amount of obesity-related microorganisms; the pathways included three types of carbohydrate metabolism. Among the treatments, Firmicutes abundances was the least in the treatments with the two types of domestic pet food containing Ptecticus tenebrifer; this did not affect the functional prediction of Tax4Fun2. In conclusion, the two types of domestic feed with Ptecticus tenebrifer were healthy and suitable for bichon frise; they could be beneficial in terms of obesity.

With the growing interest in companion animals and the rapidly expanding animal healthcare and pharmaceuticals market worldwide. With the advancements in RNAsequencing (RNA-seq) technology, it has become a valuable tool for understanding biological processes in companion animals and has multiple applications in animal healthcare. Historically, veterinary diagnoses and treatments relied solely on clinical symptoms and drugs used in human diseases. However, RNA-seq has emerged as an effective technology for studying companion animals, providing insights into their genetic information. The sequencing technology has revealed that not only messenger RNAs (mRNAs) but also noncoding RNAs (ncRNAs) such as long ncRNAs and microRNAs can serve as biomarkers. Based on the examination of RNA-seq applications in veterinary medicine, particularly in dogs and cats, this review concludes that RNA-seq has significant potential as a diagnostic and research tool. It has enabled the identification of potential biomarkers for cancer and other diseases in companion animals. Further research and development are required to maximize the utilization of RNA-seq for improved disease diagnosis and therapeutic targeting in companion animals.

Purpose : The purpose of this study is to investigate how the existence of companion animals and the type of companion animals affect the quality of life and emotional stability of adults in their 20s. Methods : The subjects of this study were adults in their twenties living in Busan who could understand the method of this study. The survey method was conducted with a questionnaire, consisting of 4 questions on general characteristics, 26 questions on quality of life, and 20 questions on emotional stability for a total of 50 questions. An independent t-test and one-way ANOVA were used to verify the difference in quality of life and emotional stability according to general characteristics. Results : As a result of analyzing the difference in the quality of life of the study subjects, the case of having a companion animal scored statistically significantly higher in the satisfaction of the physical domain, psychological domain, living environment domain, overall quality of life domain, and social domain. In addition, there was a statistically significant difference in the case of companion animals according to the type of companion animal. However, there was no statistical significance in the analysis of differences in emotional stability of study subjects according to the presence or absence of companion animals. Conclusion : This study was conducted with 400 adults in their twenties to determine the effects of the presence and absence and type of companion animals on the quality of life and emotional stability of adults in their twenties. As a result, the group with companion animals showed higher satisfaction scores than the group without companion animals in terms of quality of life. This suggests that raising companion animals for adults in their 20s has a positive effect on improving their quality of life. Therefore, it can be recommended for the physical, psychological, and social health of adults in their 20s.

Due to social phenomena such as rapid aging in Korea, nuclear familyization, single marriage, and low birth rate, the number of Companion animals and the number of households with Companion animals are increasing due to the increase in single-person households. In fact, one out of every four households has a pet, and the scale of the industry is expected to reach 6 trillion won in 2027. In particular, in a situation where the Companion animal cosmetics market is in the spotlight amid the diversification of the pet industry, there is a great lack of research on related research and industry development methods. Accordingly, this study attempted to search and analyze academic data, patented technologies, and the latest data related to pet cosmetics and provide them as basic data for the Companion animal cosmetics industry, and the results are as follows. Academic data included verification of the effectiveness of natural materials to improve the skin condition of dogs, analysis of the pet cosmetics industry, and research on ICT-converged pet cosmetics, and the industry was mainly cleaning cosmetics, with pet shampoo launches in Amorepacific, LG Household & Healthcare, and Aekyung. In the patented technology for pets, a patent has been registered for natural product material composition and formulation ratio for skin moisturizing, skin improvement, thinning, and inflammation symptom relief. As a result of this award, it was confirmed that research and development are still insufficient compared to the consumption demand of the pet cosmetics market, and it is believed that industry analysis and development research in related fields should be actively carried out.

Naringin, major citrus flavonoids, has been identified to exert antioxidative, antidiabetic, and lipid lowering effects. In this study, we examined the effect of 0.2 g/kg, 0.5 g/kg naringin supplementation for 3 times/week for 5 weeks on lipid metabolism and antithrombotic capacity in rat. Eighteen five week-old Sprague Dawley(SD) female rats, which had initial body weights of $246{\pm}9g$, were randomly divided into three groups: Control (non naringin group); Low (0.2 g/kg naringin-supplemented group); High (0.5 g/kg naringin-supplemented group). Three groups of rats were supplemented with three experimental diets for 5 weeks and we investigated antithrombotic capacity before sacrifice. Naringin did not significantly alter the body weight gain, relative organ weight. However, the level of serum triglyceride, serum free fatty acid, serum total lipid and serum glucose levels were significantly lowered compared to those of control. The high group (0.5 g/kg naringin-supplemented group) was showed significantly increased bleeding time compared to control group. These results suggest that naringin supplemental diets reduces the level of hypertension, glycosuria and fatness on the female SD rats, when orally administered below the dosage 0.5 g/kg for 5 weeks.

This study was performed to investigate the effect of dried powder of chestnut on lipid metabolism, anti-thrombotic effect in rats. Thirty 5-week-old male Sprague Dawley (SD) rats were randomly allocated into five groups and used for experiment. We examined the lipid metabolism and antithrombotic capacity of SD rats administered for 5 weeks with 0.16 g/kg, 0.5 g/kg chestnut flesh powder and 0.16 g/kg, 0.5 g/kg chestnut inner shell and flesh powder mixture, respectively. Food intake, body weight gain and food efficiency ratio were also checked. The levels of serum triglyceride and tree fatty acid were not statistically significant between the all experimental groups. However, the antithrombotic capacity and total lipid levels of the treatment groups were significantly lower than those of the negative control group. These results suggest that the supplementation of chestnut on diet lower the total lipid level in SD rats.

Eugenol, which can be extracted from clove oil, is a phenolic aromatic compound and has been found to have antibacterial, antiviral, antifungal, anticancer, anti-inflammatory, and antioxidant functions. Consequently, clove oil has long been used in several fields (food, medicine, skincare). Hence, in this study, the sensory profile of clove oil contained in milk analogs (almond, oat, and soy milks) was evaluated at different amounts (added at 0.25%-0.5% increments from 0% to 1.5%). Because of the strong scent of clove oil, the value of the evaluation for sensory profile determined in this study tended to be low. However, compared with the control group, good values in the evaluation for the sensory profile were found in all samples containing 0.25% of clove oil. We evaluated clove oil contained in milk analogs to help increase their sales through products with improved functionality.

As the number of companion animals reaches 15 million in 2022, the pet wear market is expected to grow at an average annual rate of about 14.5% from KRW 1.5684 trillion in 2014 to a market size of over KRW 6 trillion in 2027. However, most of the pet clothing and various supplies currently in circulation are either cheap, low-quality products imported from China or other countries, or expensive products released by overseas luxury brands. Therefore, it is urgent to develop a brand that can compete with luxury products coming from overseas by developing premium pet fashion products using high-end functional fabrics produced domestically. This study seeks to propose ways to revitalize the domestic pet fashion market by examining the current status of global pet fashion, the domestic textile industry, and the current status of the pet fashion market. The suggestions and expected effects are as follows. First, active support is needed for the development of products using domestically produced fabrics, such as raising awareness through various subsidy projects and contests. Second, it is expected that small and medium-sized businesses will be revitalized through the production of pet fashion products using high-quality functional knit fabrics produced in northern Gyeonggi Province. Third, it is necessary to produce high-quality premium products through continuous and intensive support from the government and collaboration between large corporations and small and medium-sized enterprises. Fourth, there is an urgent need to provide opportunities to train experts for the expected effects of starting businesses and creating new jobs.
