The design and current status of EarthCARE/CPR are described in this report. Basic design of CPR will be confirmed in this year, and engineering model development and testing will be done this year and the next year. In parallel with the development activity of CPR, algorithm development activity is in progress. The data from CPR is expected to contribute to reveal the detailed information of clouds and to the studies on global warming. It is also expected the continuation of cloud observation from CloudSat data that was launched in 2006[4].

Three growing wethers were used to investigate the differences in nitrogen (N) retention, blood plasma metabolite concentration and energy-yielding nutrient supply to muscle and adipose tissue. The wethers were fed one of three diets: timothy hay with concentrate (THD), Italian ryegrass with concentrate (IRD), and rice straw with concentrate (RSD) for 11 days. The experimental diets were adjusted to the animals to provide 100 g of daily gain. The triglyceride (TG) concentration of blood plasma in arterial and portal veins was higher with THD and IRD than with RSD. Conversely, the available amount of TG in tissues was higher with IRD. The daily amount of glucose and non-esterified fatty acids (NEFA) supplied to muscle tissue and adipose tissue was numerically higher with THD than IRD or RSD. Although N retention did not differ among the diets, it was numerically higher with THD than with IRD or RSD. The results suggest that the difference in the amount of glucose and NEFA delivered to muscle tissue may reflect the N retention in response to forage based diets.

Objective: In dryland areas of China, alfalfa hay (AH) is a possible substitute for concentrate feed for beef cattle. To evaluate the potential benefits of this substitution, we studied the effect of the ratio of AH intake to total dry matter (DM) intake on average daily body-weight gain (ADG), dietary energy utilization status, and economic benefit in Gansu province. Methods: In each of two feeding trials in 2016 (trial 1 [T1], July 3 to 17; trial 2 [T2], August 15 to September 23), crossbred male Simmental calves were allocated to low AH (LA), medium AH (MA), and high AH (HA) feeding groups (n = 4 per group). The target ADG was set as 1 kg for both trials. In a one-way-layout design based on conventional feeding practices in the province, calves received diets containing the different AH amounts, with a constant ratio of corn stover:total DM and decreasing rations of concentrate feed proportional to the increase in AH. Calves in T1 received AH at 15% (T1-LA), 23% (T1-MA), or 31% (T1-HA) of their dietary DM allowances; those in T2 received 9% (T2-LA), 24% (T2-MA), or 34% (T2-HA) AH. Results: Among the T1 groups, both ADG and economic benefit were highest in T1-LA; whereas in T2, they were higher in the T2-LA and T2-MA groups than in T2-HA. Energy digestibility did not significantly differ among the groups in either trial. The dietary AH inclusion ratios of 14% in the warm season and 8% to 21% in the cool season appeared to yield optimal ADG, metabolizable energy intake, and economic benefit. Conclusion: Low-level inclusion of AH, ranging from 8% to 21%, is a practical approach for beef cattle feeding. This modified feeding regimen likely will promote increased growth performance during the fattening stage of beef steers in dryland areas of Gansu province, China.

Endoscopic ultrasound (EUS)-guided transgastric drainage has been performed as a less invasive procedure for pancreatic fistulasand intra-abdominal abscesses occurring after surgery in recent years. However, there are no reports of EUS-guided transgastricdrainage of intra-abdominal abscesses following gastrectomy. This case report describes 2 patients who developed an intra-abdominalabscess following gastrectomy and underwent EUS-guided transgastric drainage. Both patients underwent laparoscopy-assisted distalgastrectomy with Billroth-I reconstruction for gastric cancer. The intra-abdominal abscesses were caused by postoperative pancreaticfistula that developed following gastrectomy. One patient underwent naso-cystic drainage and the other underwent only a needlepuncture of the abscess cavity. EUS-guided drainage was performed safely and effectively, although 1 patient developed gastroduodenalanastomotic leakage related to this procedure. In summary, EUS-guided transgastric drainage is safe and technically feasible evenin post-gastrectomy patients. However, it is necessary to be careful if this procedure is performed in the early period followinggastrectomy.
Laser methane detector-based quantification of methane emissions from indoor-fed Fogera dairy cows

Objective: Portable laser methane detectors (LMDs) may be an economical means of estimating CH<sub>4</sub> emissions from ruminants. We validated an LMD-based approach and then used that approach to evaluate CH<sub>4</sub> emissions from indigenous dairy cows in a dryland area of Ethiopia. Methods: First, we validated our LMD-based approach in Simmental crossbred beef cattle (n = 2) housed in respiration chambers and fed either a high- or low-concentrate diet. From the results of the validation, we constructed an estimation equation to determine CH<sub>4</sub> emissions from LMD CH<sub>4</sub> concentrations. Next, we used our validated LMD approach to examine CH<sub>4</sub> emissions in Fogera dairy cows grazed for 8 h/d (GG, n = 4), fed indoors on natural-grassland hay (CG1, n = 4), or fed indoors on Napier-grass (Pennisetum purpureum) hay (CG2, n = 4). All the cows were supplemented with concentrate feed. Results: The exhaled CH<sub>4</sub> concentrations measured by LMD were linearly correlated with the CH<sub>4</sub> emissions determined by infrared-absorption-based gas analyzer (r<sup>2</sup> = 0.55). The estimation equation used to determine CH<sub>4</sub> emissions (y, mg/min) from LMD CH<sub>4</sub> concentrations (x, ppm m) was y = 0.4259x+38.61. Daily CH<sub>4</sub> emissions of Fogera cows estimated by using the equation did not differ among the three groups; however, a numerically greater milk yield was obtained from the CG2 cows than from the GG cows, suggesting that Napier-grass hay might be better than natural-grassland hay for indoor feeding. The CG1 cows had higher CH<sub>4</sub> emissions per feed intake than the other groups, without significant increases in milk yield and body-weight gain, suggesting that natural-grassland hay cannot be recommended for indoor-fed cows. Conclusion: These findings demonstrate the potential of using LMDs to valuate feeding regimens rapidly and economically for dairy cows in areas under financial constraint, while taking CH<sub>4</sub> emissions into consideration.
