  • In this study, we determined the effect of the mulberry leaf powder on blood lipid metabolism and liver function improvement of mice fed a high fat diet. The mulberry leaf showed a moisture content of $10.74{\pm}0.56%$, ash $9.67{\pm}0.56%$, crude protein $25.24{\pm}1.02%$, and crude fat $2.66{\pm}0.08%$. In the group with high fat diet supplemented with mulberry leaf powder, serum low-density lipoprotein (LDL-cholesterol) and total cholesterol levels were significantly lower (p<0.05); also, serum phospholipid and aspartate amino transferase (AST) levels were significantly lower (p<0.05). Serum insulin and leptin levels were high in mice fed a high fat diet; however, addition of mulberry leaf powder 10% in the diet had no significant effect on blood insulin and leptin control. The results of the study suggested that various plant sterols in mulberry leaf improve lipid metabolism and liver function in ICR-mice.

  • This experiment was conducted to compare the productivity of five silage corn varieties. Corn varieties were Pioneer 3144(P 3144), 3160(P 3160), 3282(P 3282), 3352(P 3352) and Suweon 19(S 19) and were seeded on May 2 and harvested on August 15. Ratios of stalk, leaf and ear, chemical composition and yields of nutrients were investigated in respective corn part. Experimental design was accepted by Latin square arrangement with five replicates and each plot had twenty two plants. The results obtained were as follows: 1. Crude portein, crude ash and nitrogen free extract(NFE) contents of whole plant ranged from 6.32 to 7.18%, 5.16 to 7.43% and 52.62 to 57.90%, respectively, and there were no significant(P>.Ol) differences between varieties. Crude protein and NFE content were the highest in ear between corn parts. 2. Crude fiber conent of whole plant ranged from 18.98 % to 24.01 %, and was the highest in suweon 19 and the lowest in P 3352(P<.01). Crude fiber content was the highest in stem and the lowest in ear, However, crude fat content(2.03-3.66 %) vice versa. 3. Yields of organic matter, crude protein, crude fat, NFE and TDN per 10a were the greatest(P< .01) in P 3282, however crude fiber yield was the highest(P<.Ol) in P 3352. 4. Ratios of different part to total dry matter yield ranged from 12.7 %(P 3352) to 17.8 %(P 3160) for leaf, 44.5(P 3352) to 66.9 %(P 3160) for stem and husks, and 16.9 %(P 3282) to 42.8 %(P 3352) for ear, and there were significant differences between corn varieties(P<.Ol). Consequently, P 3352 has the greatest nutrient yields, particularly by ear, and P 3282 has a great nutrient yield by stem. This result suggested that could be appear a better character of silage corn by hybridization of this two corn varieties.

  • 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.

  • Plant-based, grain-free, and gluten-free diets have been the focus of recent research, as part of the premiumization trend in dog food. However, the lack of comprehensive information regarding carbohydrates in dog food makes it difficult to produce nutritionally balanced meals. Therefore, we aimed to evaluate the nutritional value of carbohydrate ingredients commonly used in commercial dog foods. First, using data from Euromonitor, we investigated the trends in the dry dog food industry and analyzed the annual volume of dry dog food sales, as well as the dog population from 2010 to 2021 in Korea. The growth of the market was greatest in 2021, when the total value of sales of premium dry dog food was 254.3 billion KRW (Korean won) more than in 2010. In addition, sales of dry dog food by age category were marked by a significant increase (404.8%) in the market for dry food for senior dogs. Second, we examined the frequency of carbohydrate ingredients used in dry dog food and conducted a proximate analysis of the top 10 most frequently used ingredients. Subsequently, we analyzed the crude protein, crude fat, and nitrogen-free extract in the carbohydrate ingredients based on dry matter (DM) and calculated the ratio of metabolic energy content supplied from each nutrient in the carbohydrate ingredients. The ratio of metabolic energy content in the carbohydrate ingredients indicated that mung beans had the highest crude protein content (31.3%), whereas oats exhibited the highest crude fat content (23.3%). Sweet potatoes had the highest nitrogen-free extract content, measuring at 93.6%. The results of this study are expected to provide a valuable foundation for the growth and development of the domestic dog food industry, while also contributing to a deeper understanding of the specific role of each ingredient as a carbohydrate source.
