This study was conducted to determine changes in internal temperature and chemical composition during the composting of broiler litter(BL) and to evaluate the feasibility of use of a small-scale pelletizer for the pelleting of composted BL. BL was composted for 4 weeks in an wooden cell with a size of 1 m length $\times$ 1 m width $\times$ 1.2 m height. Internal temperature reached to peak(68$^{\circ}C$) at the fourth day and thereafter gradually reduced. Among chemical components in BL, composting reduced organic matter content and increased dry matter and indigestible protein(ADF-CP) contents. When BL was pelleted using an economical small-scale pelletizer, the proper die diameter was 8~18 mm and the proper moisture content of composted BL was 20~25%. Beyond these proper conditions, addition of heat and pressure or pellet aids may be necessary. Pelleting of BL resulted in nearly threefold increase of bulk density, significant moisture evaporation, and little change in chemical components except for increased indigestible protein. In conclusion, BL may be converted into a feed with low to medium nutrition by the composting and pelleting process.

This study was carried out to investigate the clinical characteristics of 78 diabetics by body fat distribution pattern. It was based on the survey of nutritional status, anthropometric measurements and serum components of the patients. The results were as follows: the average ages of male and female subjects were 57.1, and that of female subjects was 58.9, respectively. The average diabetic durations of male and female subjects were 4.8 and 5.9 years, respectively. In male, the ratio of upper body obese subject was 62.5% and the lower body obese subjects was 37.5%, while those of female were 69.4% and 30.6%, respectively. In nutrient intake state, there was no significant difference between male and female subjects, but calory intake of upper body obese subjects was difference between male and female subjects, but calory intake of upper body obese subjects was tend to be higher in both male and female subjects. among the three major nutrients/calory ratio, protein/calory ratio was significantly lower in the male upper body obese subjects than in the male lower body obese subjects. Since weight, circumference of arm and waist, waist hip ratio(WHR) of both male and female subjects, body muscle mass(BMM) of male subjects and body mass index (BMI) of female subjects were significantly higher in upper body obese group, upper body obese subjects represented ore fat than lower body obese subjects. In male subjects, hemoglobin(Hb), A/G of upper body obese subjects were lower than the standard value, but there was no significant difference in the serum components between two subjects. In female subjects, Hb and A/G of lower body obese subjects were lower than those of the normal subjects, but Hb and Ht of upper body obese subjects were significantly higher than those of the lower body obese subjects.

The effect of mixed treatments of wood vinegar and sulfonylurea-based herbicides on weed control, yield and yield components, and quality of rice was investigated. Two herbicides were tested namely: imazosulfuron-ethyl+thiobencarb[ethyl-1-(2-chloroimidazo[1,2-$\alpha$]pyridin-3-ylsulfonyl)-3-(4,6-dimethoxypyrimidin-2-yl) urea+S-4-chlorobenzyl diethyl(thiocarbamate)], and bensulfuronmethyl+butachlor [methyl $\alpha$-[(4,6-dimethoxypyrimidin-2-ylcarbamoyl)sulfamoyl]-o-toluate+N-butoxymethyl-2-chloro-2',6'-diethylacetanilide]. The experiment was carried out in a randomized complete block design with 3 replications and 5 treatments. Treatments used were recommended(RH: 100%) and half-recommended(HRH: 50%) application rates of each herbicide. Half-recommended application rates were combined with 1 mL wood vinegar $500mL\;water^{-1}$(500) and 1 mL wood vinegar $1000mL\;water^{-1}$(1000) wood vinegar. Plots for no herbicide treatments were also prepared and used as control. Results showed that wood vinegar significantly increased efficacy of HRH in bensulfuron-methyl+butachlor while high efficacy was already obtained in HRH treatment of imazosulfuron-ethyl+thiobencarb. Wood vinegar did not improve the efficacy of imazosulfuron-ethyl+thiobencarb but improved rice yield. Significantly similar rice yields were obtained in the HRH+1000 WV and RH treatments of both herbicides. There were no significant variations in the yield components among the treatments; however, differences in yield can be attributed to the variations in the spikelet number and ripening ratio. Data on rice quality analysis did not show clear trend on the effects of the treatments on grain appearance and nutritional quality.

Xinjiang province is the main camel feeding area in China with a large square, and camel milk from different areas have different qualities. By now, there are few reports about the quality of camel milk from different areas of Xinjiang province in China. In this study, seven batches of camel milk and one batch of cow milk were collected, and the contents of fat, protein, lactose, total solid, and nonfat milk solid of these milk samples were determined, as well as the contents of lysozyme and vitamin C. All samples were scored and compared by principal component analysis score and comprehensive weighted multi-index score. As the results, camel milk from different areas showed different contents of fat (4.62%-7.02%), protein (3.34%-3.95%), lactose (3.85%-4.79%), total solid (13.59%-17.00%), nonfat milk solid (8.55%-9.73%), vitamin C (12.10-41.25 ㎍/mL), and lysozyme (8.70-22.80 ㎍/mL), as well as different qualities. This variation would help people to know more about quanlity of camel milk in Xinjiang province. Camel milk from Jeminay showed the best quality, and then followed by camel milk from Fukang, Changji, and Fuhai, while cow milk showed the lowest score. Therefore, Jeminay is the most suitable place for grazing camels. Our findings show the different qualities of camel milk in different distribution areas of Xinjiang province, and provide an insight for the evaluation of camel milk. In the present study, only seven components in camel milk were determined, many other factors, such as cfu, mineral, and other vitamins, have not been considered.

To cope with climate change, we compared the quality of naked oats (Avena sativa L.) cultivated in different regions. Naked oats were collected from domestic farms in different cultivation regions grouped as G1 and G2 for 3 years (2020-2022). The appearance, quality, and nutritional and functional compounds in the samples were assessed. In terms of appearance quality, the brightness and yellowness of the samples from the G1 region were significantly lower than those of the samples from the G2 region in 2020; however, no differences were observed between cultivation regions in the other 2 years. The results of testing the vitality of naked oats seeds showed that the electrical conductivity value was significantly lower in the samples from the G1 region than in those from the G2 region only in 2022. Among the nutritional components, moisture content was higher in the G2 region than in the G1 region over all 3 years, and the crude protein content was significantly higher in the G2 region than in the G1 region over all years. Carbohydrate content was significantly higher in the G1 region than in the G2 region in all 3 years and was inversely proportional to the crude protein content. The crude fat content tended to be significantly higher in the G1 region than in the G2 region, except in 2022. The levels of beta-glucan, a functional compound rich in naked oats, ranged between 3.4% and 4.2%, and except in 2020, there was no significant difference between cultivation regions. In addition, the content of avenanthramides, representative functional compounds that exist only in oats, was assessed. Over 2 years, in 2021 and 2022, the avenanthramide content was in the range of 2.4-20.7 ㎍/g and tended to be significantly higher in the G2 region than in the G1 region in both years. According to a survey of the average and minimum temperatures during the growing season of naked oats from 2020 to 2022, the average and minimum temperatures in January in the G2 region, which is the cultivation-limit area, were similar to those in Haenam in the G1 region. In conclusion, differences in nutritional and functional compounds were observed in naked oats grown in different cultivation areas. Therefore, considering the cultivation area of naked oats is expanding because of climate change, changes in the compounds that affect quality should be investigated.
