“…The indigenous pig breeds are vital for Lao economic development and food supply, especially the rural communities where approximately 9−14% of a household's annual income is from native pig production (Xayalath et al, 2020). Moo Lath pig is one of the famous native pig breeds in Laos.…”

This study aims to evaluate the effects of the birth weight of crossbred Moo Lath x Duroc (CMD) gilts on their puberty and first mating age, including the body condition and morphology. The litter size and birth weight of their offspring were also evaluated. Eighteen (18) CMD gilts were selected after weaning and kept in an individual pen 1.5 x 2 x 1 m after puberty. The gilts were grouped into three groups based on birth weight: groups A, B, and C (with <0.7, ≥0.7−0.9≤, and >0.9 kg, respectively). 15 mature purebred Moo Lath (PML) gilts reared by farmers were also involved in this study to compare the morphology between the CMD and PML at first mating. There was no difference in the age and body weight of CMD gilts at puberty and first mating among the studied groups. However, the gilts in group A showed a lower mean age at puberty, and marginally lighter body weight than those in groups B and C. Birth weight showed a significant influence on the backfat thickness at puberty and first mating (P<0.039 and 0.031). The CMD gilts could have their first mating at 193 days, that is at their 3 rd and 4 th estrous cycle, with approximately 40 kg of body weight, 38 mm of backfat thickness, 90 cm of heart girth, 100 cm of body length, and 51 cm height at wither. The CMD gilts' birth weight did not influence their litter size, but influenced their offspring's birth weight.

In Laos, pork is the second most common meat source after fish and its demand is constantly growing annually. Recently, pork has been in short supply in urban and rural areas, forcing the Lao government to import thousands of tons from neighbouring countries, particularly Thailand, Vietnam, and China. In view of the earlier-mentioned, this study aimed to look at the current situation of pork production and supply in Vientiane Capital (VC) and the prospects for pork production in VC, Laos. In 2020, Laos had a pig population of about 4.3 million, with over 91.0% being native pigs and only 366,000 heads being European pig types, with over 54.0% being reared in VC. In 2019, Laos had 578 commercial pig farms, with 188 farms (33.0%) of which were located in VC. Despite the fact that most of the commercial pig farms are located in VC, pork demand is still high, with the consequence that consumers need to pay a high price. For example, in 2020, the average price of pork was 46,000 LAK/kg ($ 4.00); it rose up by 22.0% against 2019 and by 11.0% from 2015. Several feed raw materials (maize, cassava, and rice bran) are produced in VC, and nearby provinces, which the farmers can use to combat the dramatic changes or instabilities of feed price. We concluded that there is a high potential to develop pig production in VC, especially local breeds considering the high demand for premium pork and more available raw feed materials.

Abstract. Indigenous pigs are essential domestic animals for rural life and meat supply in Laos, especially for ethnic people in remote areas. Northern provinces have the most numerous indigenous pig populations, i.e. covering 84 % of the total pig population. This study was conducted in northern Laos, where 164 pig-raising households, 325 sows and 1246 piglets were included. The study aimed to observe the general trend of change in indigenous pig utilization and the altered reproductive performance regarding village location and rearing systems. The semi-structured questionnaires were a key tool for gathering data required through personal interviews and field observations. Two types of indigenous Lao pig breeds (locally named Moo Lath and Moo Hmong) were found in study areas. The village locations were not influencing on reproductive performance of indigenous Lao pigs. Larger litter size and birth weight (P<0.004–0.000) was found in the second cluster (15 to 30 km away from downtown) with an average of 8.24 heads and 0.88 kg, while the first (<15 km) and third (>30 km) clusters had 7.72 versus 7.12 heads, and 0.70 versus 0.63 kg, respectively. Conversely, the second cluster had lower litter per year (P<0.001) by 1.04, compared to 1.38 for the first and third clusters. The free-scavenging rearing system (FRS) had a higher litter size (8.5) than the confinement (CRS) and semi-scavenge (SRS) rearing system (7.36 versus 7.54). The FRS had a marginally smaller litter per year (0.87) that differed from the CRS and SRS (1.45 and 1.41). The CRS had a shorter suckling period (2.38 months) with a lower weaning weight (6.74 kg), while the FRS and SRS had longer (2.72 versus 2.8 months) and higher weaning weight (7.76 and 7.57 kg). The mortality before weaning was 15 %, and no difference was found related to the villages' location or rearing systems (P>0.070 versus 0.839). Around 56 % of the piglet's deaths were due to poor management that caused piglets to be crushed/injured by sow or starvation. More than 54 % of farmers did not keep sows in pens before the farrowing, and 53 % of sows gave birth near forests. In conclusion, the village locations and rearing systems did not influence the reproductive performance of indigenous pigs in northern Laos. However, pre- and post-farrowing management had a strong effect on it. During the whole study, we took into consideration the successful example of Hungarian Mangalica pig, which could find a proper new role in the global premium markets. Our results suggest that similar complex semi-intensive farm operations as indigenous Mangalica pig farms in Hungary should be a great option for introducing and adapting to improve indigenous pig performance in Laos.
