Limited data about the effects of various factors on forage quality and β-carotene content of rye produced in Korea are available, so this study investigated the effects of two preservation methods. Samples were collected from rye harvested every 5 days between April 25 and May 31, and comparisons were done among rye silage wilted for different periods of time and hay of three growth stages of rye. For the silage, dry matter (DM), acid detergent fiber (ADF), and neutral detergent fiber (NDF) contents increased with advanced maturity of rye, whereas crude protein, in vitro dry matter digestibility (IVDMD), total digestible nutrients (TDN), relative feed value (RFV), and DM loss decreased (p < 0.0001). Wilting increased the DM content and pH value significantly (p < 0.0001). Silage harvested at the heading stage had the lowest pH value (4.45), propionic acid (0.83 g/kg DM), butyric acid (0 g/kg DM), and fungi and yeast populations (3.70 Log CFU/g of fresh matter [FM]); conversely, it had the highest lactic acid (9.7 g/kg DM), lactic acid bacteria (LAB) (6.87 Log CFU/g of FM), total microorganisms (TM) (7.33 Log CFU/g of FM), and Flieg's score (70) (p < 0.0001). Wilting elevated LAB and TM populations, but it had no consistent effect on other fermentation products. Both delayed harvest and prolonged wilting decreased β-carotene content. Rye silage harvested around May 9 (heading stage) with 24 h of wilting was preferred for highland, Pyeongchang. For rye hay, advanced maturity decreased DM loss, IVDMD, TDN, and RFV, but it increased DM, ADF, and NDF significantly (p < 0.05). β-carotene was decreased by delay of hay-making. Consequently, to attain lower DM loss and higher hay quality, the harvest date of May 9 (heading stage) is recommended.

Although it has recently been regulated for use as an eco-friendly policy in Korea, the use of EPS (Expanded Polystyrene) cooling boxes, which are used as cold chain delivery insulation boxes for fresh agricultural and livestock products, is also increasing rapidly as e-commerce logistics such as delivery have increased rapidly due to COVID-19. Studies were conducted to optimize the EPS cooling container through internal air heat flow of CFD (Computational Fluid Dynamics) analysis and FEM (Finite Element Method) random vibration analysis using domestic PSD (Power Spectral Density) profile of the EPS cooling box to which the refrigerant is applied in this study. In the analysis of the internal air heat flow by the refrigerant in the EPS cooling box, the application of vertical protrusions inside was excellent in volume heat flow and internal air temperature distribution. In addition, as a result of random vibration analysis, the internal vertical protrusion gives the rigid effect of the cooling box, so that displacement and stress generation due to vibration during transport are smaller than that of a general cooling container without protrusion. By utilizing the resonance point (frequency) of the EPS cooling box derived by the Model analysis of ANSYS Software, it can be applied to the insulation and cushion packaging design of the EPS product line, which is widely used as insulation and cushion materials.

Objective: With improvements in living standards and increase in global population, the demand for meat products has been increasing; improved meat production from livestock could effectively meet this demand. In this study, we examined the differences in the muscle traits of different male crossbred sheep and attempted to identify key genes that regulate these traits. Methods: Dubo sheep×small-tailed Han sheep (DP×STH) and Suffolk×small-tailed Han sheep (SFK×STH) were selected to determine meat quality and production performance by Masson staining. Transcriptome sequencing and bioinformatic analysis were performed to identify differentially expressed genes (DEGs) related to meat quality. The presence of DEGs was confirmed by real-time polymerase chain reaction. Results: The production performance of SFK×STH sheep was better than that of DP×STH sheep, but the meat quality of DP×STH sheep was better than that of SFK×STH sheep. The muscle fiber diameter of DP×STH sheep was smaller than that of SFK×STH sheep. Twenty-two DEGs were identified. Among them, four gene ontology terms were related to muscle traits, and three DEGs were related to muscle or muscle fibers. There were no significant differences in the number of single nucleotide mutations and mutation sites in the different male parent cross combinations. Conclusion: This study provides genetic resources for future sheep muscle development and cross-breeding research.

In this study, a meta-analysis was performed to determine the correlation between the expression of tight junction protein in the intestine and the productivity of broiler chickens. A total of 9 papers were selected in which the result values consisted of the mean and standard deviation value, and the standardized mean difference was calculated to compare the mean of the control and treatment groups. A meta-regression test was conducted to determine the effect of each type of tight junction protein. The TJPs observed in each study were claudin1, claudin2, claudin3, occludin, ZO1, ZO2, etc., and the indicators to indicate the productivity of broilers were body weight gain (BWG), feed intake (FI), and feed conversion rate (FCR), average daily feed intake (ADFI), average daily gain (ADG), and feed/gain ratio (FPG). Although there are differences depending on the type of TJP, it was found that the change in expression level had a close effect on the productivity of broilers. In particular, occludin significantly correlated with body weight gain, feed intake, and feed conversion rate. Based on the results of this study, a study on a method to effectively increase the expression level of TJP is expected to contribute to improving the productivity of broilers and producing safe livestock products.

Currently, the web page that provides residual substance information provides information on residual acceptance criteria in food for pesticides and veterinary drugs. Residual substances refer to pesticides or veterinary drugs that are left in agricultural, livestock, or marine products after being used by diluting them thousands of times. However, users are experiencing inconvenience due to the lack of information on pesticides and veterinary drugs, delays in search time, and Web page errors. In addition, the manager has the inconvenience of manually entering information such as residual acceptance criteria and analysis methods. Thus, this paper proposes a system that can efficiently manage and update the history of changes in information, such as residual material standards for pesticides, animal medicines and the characteristics of drugs.

The article deals with issues related to the tradition of carpet production on the territory of Kazakhstan where, for the most part, tribes engaged in nomadic livestock raising lived. Analyzing the technological component of this traditional craft, the author focuses on the main factor that influenced carpet weaving along with arts and crafts-the nomadic method of production of the Kazakhs. The study of the ideological component that accompanies the process of making various types of carpets allows us to conclude that it has a sacred meaning and subordination to myth, rite, and ritual. At the mythmaking level, the process of making carpets, like any other activity among nomads, personified the process of creating the world, the marriage of Kok-Tengri (Heaven) and Zher-Su (Earth), and the creation of the Cosmos from Chaos. The process of carpet weaving, as well as the process of making felt, symbolized the act of creation, the marriage of Heaven and Earth, and male and female principles. The study of various types of ornaments that Kazakhs and their ancestors used to decorate carpets allows us to conclude that the ornament applied to carpet products was the bearer of the most valuable information about the mythological worldview of the people. Carpets in their structure reproduced the structure of the Universe, which has a binary, ternary, and quaternary system. The ornament has turned into a kind of coded text, reflecting ideas about the cosmogonic structure of the Universe and an awareness of the harmony of the world. The location of Kazakhstan on the northern routes of the Sogdian Road (Great Silk Road) allowed the spread of various ideas, due to which carpet weaving was influenced by other peoples in technical and stylistic design.

Livestock production depends on the utilization of nutrients, and when this is accomplished, there is accelerated momentum toward growth with a low cost-to-feed ratio. Public concern over the consumption of pork with antibiotic residues in animals fed antibiotic growth promoters (AGP) has paved the way for using other natural additives to antibiotics, such as herbs and their products, probiotics, prebiotics, etc. Numerous feed additives are trending to achieve this goal, and a classic example is vitamins and minerals. Vitamins and minerals represent a relatively small percentage of the diet, but they are critical to animal health, well-being, and performance; both play a well-defined role in metabolism, and their requirements can vary depending on the physiological stage of the animals. At the same time, the absence of these vitamins and minerals in animal feed can impair the growth and development of muscles and bones. Most commercial feeds contain vitamins and trace minerals that meet nutrient requirements recommended by National Research Council and animal feeding standards. However, the potential variability and bioavailability of vitamins and trace elements in animal feeds remain controversial because daily feed intake varies, and vitamins are degraded by transportation, storage, and processing. Accordingly, the requirement for vitamins and minerals may need to be adjusted to reflect increased production levels, yet the information presented on this topic is still limited. Therefore, this review focuses on the role and function of different sources of minerals, the mode of action, the general need for micro and macro minerals in non-ruminant diets, and how they improve animal performance.

This study was performed to investigate the distribution of mosquito vectors related to the zoonotic disease in Daejeon. Samples were taken using a blacklight trap once a month from March to November 2021 at the slaughterhouse in Daejeon. A total of 820 mosquitoes were captured and classified into 5 genera and 8 species. Among the collected mosquitoes, 319 (38.9%) and 295 (35.93%) were Aedes vexans nipponii and Culex pipiens pallens, respectively, making them the dominant species. The overall number of mosquitoes collected started to increase from May and reached the largest value of 329 (40.12%) in June. Trapped mosquitoes are created 72 pools by environmental condition and by species. The pools were tested by PCR methods for 7 zoonotic pathogens. Flavivirus-positive products were confirmed by DNA sequencing. Japanese encephalitis viruses were detected in 3 pools collected from cow lairage (Culex pipiens pallens) in May, cow by-product processing room (Aedes vexans nipponii) in June and cow lairage (Mansonia uniformis) in June. Culex flavivirus were detected in 4 pools. Based on the results of this study, it is considered that continous surveillence of mosquitoes in livestock assembly facilities (slaughterhouse) should be performed for controlling mosquito populations and mediating disease spread by mosquitoes.

Objective: A study was conducted to determine the chemical composition of banana meal and rice bran from Australia or South-East Asia and test the hypothesis that there are no differences in rice bran produced in different countries, but there are differences between full-fat and defatted rice bran. Methods: Two sources of banana meal and 22 sources of rice bran (full-fat or defatted) from Australia or South-East Asia were used. All samples were analyzed for dry matter, gross energy, nitrogen, amino acids (AA), acid hydrolyzed ether extract (AEE), ash, minerals, total starch, insoluble dietary fiber, and soluble dietary fiber. Banana meal was also analyzed for sugars including glucose, fructose, maltose, sucrose, stachyose, and raffinose. Results: Chemical analysis demonstrated that banana meal from the Philippines is primarily composed of starch. Full-fat rice bran from Australia had greater (p<0.05) concentrations of AEE, lysine, and glycine than samples from the Philippines and Vietnam. Full-fat rice bran from Australia and Thailand had greater (p<0.05) concentrations of gross energy and most AA than rice bran from Vietnam. Full-fat rice bran from Australia had greater (p<0.05) concentrations of tryptophan and manganese than all other sources, but full-fat rice bran from the Philippines contained less (p<0.05) zinc than all other sources of rice bran. Gross energy, AEE, and copper were greater (p<0.05) in full-fat rice bran compared with defatted rice bran, but defatted rice bran contained more (p<0.05) crude protein, ash, insoluble dietary fiber, total dietary fiber, AA, and some minerals than full-fat rice bran. Conclusion: Banana meal is a high-energy source that can be used as an alternative ingredient in livestock diets. Full-fat rice bran from Australia and Thailand contained more concentrations of AEE and AA than samples from the Philippines or Vietnam. Full-fat rice bran had more gross energy and AEE than defatted rice bran, whereas defatted rice bran contained more crude protein, ash, and total dietary fiber.
