Vientiane, Laos

National University of Laos is the leading university in Vientiane, the capital of Laos. Founded in 1996, with departments brought in from other existing colleges, it is the only national university in the country. NUOL accepts top students from Laos with few international students. National University of Laos is cooperating with various international universities, especially from Japan. The university is a partner of the Greater Mekong Sub-region Academic and Research Network and ASEAN University Network . Wikipedia.

The impact of replacing soybean crude protein (CP) with CP from ensiled taro leaves (ET) on growth performance, carcass traits, and organ weights in Landrace × Yorkshire (LY) and Moo Lath (ML) Lao pigs was studied. Twenty-four castrated male pigs, 12 of each breed, were allocated to the treatments according to a completely randomized 3 × 2 factorial (three levels of ET × two breeds) arrangement with four pigs per treatment. The pigs were kept in individual pens and were fed at 4 % dry matter of body weight for 105 days. The control diet (ET0) was formulated with soybean meal as the main CP source, and in the other two diets, soybean CP was replaced to 25 % (ET25) and 50 % (ET50), respectively, with CP from ensiled taro leaves. Calculated metabolizable energy intake decreased with increasing replacement of soybean CP in the diet, while dry matter intake (DMI), CP intake (CPI), average daily gain (ADG), and feed conversion ratio (FCR) were unaffected. Carcass weight, back fat thickness, and dressing percentage were unaffected by soybean CP replacement, while organ weights (except for spleen) increased (P < 0.001) when soybean CP was replaced by CP from ensiled taro leaves in the diet. LY pigs had higher (P < 0.001) DMI, CPI, and ADG and better (P < 0.001) FCR than ML pigs. LY pigs had higher carcass weight (P < 0.001), lower back fat thickness (P < 0.001), and higher organ weights (P < 0.05-0.001) than the ML pigs. In conclusion, taro leaf silage can replace up to 50 % of soybean CP in the diet of growing Lao LY and ML pigs without negative effects on performance and carcass traits. Source

The Nam Ngum 1 hydropower project took place in the early 1970s and displaced about 23 villages and 570 households. This research focuses on two resettlement villages: Pakcheng and Phonhang. A comparison is made concerning the livelihood conditions of these two villages, resettled in 1968 and 1977, respectively. The methodology involved consultation meetings in each village and one-on-one interviews of 100 households (50 households per village). This case study has determined that in terms of family income for these two villages, Pakcheng is significantly more affluent than Phonhang. This is probably because Pakcheng is located along a main road and has far better facilities and irrigation systems. © 2013 Copyright Taylor and Francis Group, LLC. Source

A survey was carried out in smallholder farming systems in the districts of Borrikun, Khamkeuth, and Pakkading, in central Lao People's Democratic Republic, to assess the feeding regime and health status of local Lao pigs. In total, 216 farmers, 72 in each district, were interviewed using a questionnaire. Feed samples were collected for nutrient analysis and pen soil samples for mineral content determination. Farmers kept sows of native breeds such as Moo Lath, Moo Chid, and Moo Hmong. The number of sows per household was low (1.1 ± 0.1, 1.1 ± 0.1, and 1.2 ± 0.1 in Borrikun, Khamkeuth, and Pakkading, respectively) and pigs were mainly fed with rice bran and fresh cassava roots. Daily protein and mineral (Calcium, phosphorus, potassium, and sodium) allowances were lower than requirements. In all districts, the number of piglets at birth was around seven and pre-weaning piglet mortality was around 20 %. The most common causes of piglet death, before weaning, were diarrhea, runts, and squashed piglets. Most piglets were weaned after 4 months of age, but in the Borrikun and Pakkading districts, 11-16 % of households were weaned at <4 months. In all districts, pig management was mainly women's responsibility (around 90 %) and most farmers spent less than 1 h per day on pig management. A feasible and cheap way to increase nutrient supply to local pigs in central Lao People's Democratic Republic would be to include more fresh plant material (e.g., thick head, taro) and salt in the diet. Information and education on improving pig management should be targeted towards women. Source

Background: Activities and diet during the postpartum period are culturally dictated in many Southeast Asian cultures, and a period of confinement is observed. Plants play an important role in recovery during the postpartum period in diet and traditional medicine. Little is known of the Kry, a small ethnic group whose language was recently described, concerning its traditions and use of plants during pregnancy, parturition, postpartum recovery and infant healthcare. This research aims to study those traditions and identify medicinal plant use.Methods: Data were collected in the 3 different Kry villages in Khammouane province, Lao PDR, through group and individual interviews with women by female interviewers.Results: A total of 49 different plant species are used in women's healthcare. Plant use is culturally different from the neighboring Brou and Saek ethnic groups. Menstruation, delivery and postpartum recovery take place in separate, purpose-built, huts and a complex system of spatial restrictions is observed.Conclusions: Traditions surrounding childbirth are diverse and have been strictly observed, but are undergoing a shift towards those from neighboring ethnic groups, the Brou and Saek. Medicinal plant use to facilitate childbirth, alleviate menstruation problems, assist recovery after miscarriage, mitigate postpartum haemorrhage, aid postpartum recovery, and for use in infant care, is more common than previously reported (49 species instead of 14). The wealth of novel insights into plant use and preparation will help to understand culturally important practices such as traditional delivery, spatial taboos, confinement and dietary restrictions, and their potential in modern healthcare. © 2011 Lamxay et al; licensee BioMed Central Ltd.
