Cím:Reproductive performance of indigenous Lao pigs reared by small-scale farmers in northern provinces of Laos / Xayalath, Somsy, Novotni-Dankó Gabriella, Balogh Péter, Brüssow Klaus-Peter, Rátky József
Megjegyzések:Indigenous pigs are essential domestic animals for rural life and meat supply in Laos, especiallyfor 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-raisinghouseholds, 325 sows and 1246 piglets were included. The study aimed to observe the general trend of change inindigenous pig utilization and the altered reproductive performance regarding village location and rearing sys-tems. The semi-structured questionnaires were a key tool for gathering data required through personal interviewsand field observations. Two types of indigenous Lao pig breeds (locally named Moo Lath and Moo Hmong) werefound in study areas. The village locations were not influencing on reproductive performance of indigenous Laopigs. Larger litter size and birth weight (P <0.004?0.000) was found in the second cluster (15 to 30 km awayfrom downtown) with an average of 8.24 heads and 0.88 kg, while the first (<15 km) and third (>30 km) clus-ters had 7.72 versus 7.12 heads, and 0.70 versus 0.63 kg, respectively. Conversely, the second cluster had lowerlitter per year (P <0.001) by 1.04, compared to 1.38 for the first and third clusters. The free-scavenging rear-ing system (FRS) had a higher litter size (8.5) than the confinement (CRS) and semi-scavenge (SRS) rearingsystem (7.36 versus 7.54). The FRS had a marginally smaller litter per year (0.87) that differed from the CRSand 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 and7.57 kg). The mortality before weaning was 15 %, and no difference was found related to the villages' locationor rearing systems (P >0.070 versus 0.839). Around 56 % of the piglet's deaths were due to poor managementthat caused piglets to be crushed/injured by sow or starvation. More than 54 % of farmers did not keep sows inpens before the farrowing, and 53 % of sows gave birth near forests. In conclusion, the village locations and rear-ing 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 considerationthe successful example of Hungarian Mangalica pig, which could find a proper new role in the global premiummarkets. Our results suggest that similar complex semi-intensive farm operations as indigenous Mangalica pigfarms in Hungary should be a great option for introducing and adapting to improve indigenous pig performancein Laos.
