Abstract

This study was aimed to determine the profiles of pig farming systems. Participatory situationanalysis was employed to gain data relating to pig profiles in the urban and rural areas of Manokwari.Due to the interests of combining many correlated data, multivariate analysis using Principal ComponentAnalysis (PCA) was performed. Cluster Analysis using Agglomerative Hierarchical Clustering wasapplied for analysis of merge samples based on similarity in components’ composition across sites.There were various twelve classes of pig profiles in Manokwari. In principal component of the first axiscorrelation of several components shows strong positive relation e.g. in piglets, sows, and total herd size.Status of region in the first axis of PCA (P1) through which pigs were raised had negative correlation,including grower, household member and pig production. In the second axis (P2), negative correlationswere shown in piglets, grower, boars, total herd size and the Pig Production Potential (PPP). Status ofregion has underpinned profiles of pigs. Several farmers were able to manage their farm continuity in asteady composition. Selling pigs was the main aim and few farmers play a role as pure breeder.

Abstract

The objective of this study was to depict the pig farming performances of three different nativePapuan tribes, i.e. Byak, Onate and Arfak. Sites in Biak were taken from Samofa District. Sites in Yapenwere taken from South Yapen District comprised of Famboaman, Anotaurei, Mariadei and Mantembuvillages. Site in Manokwari was chosen at Sub-district of Wosi. Participatory research using interviewand observation was done towards 105 pig farmers. One-way analysis of variance and Pearson Chisquare(χ2) were used to analyse data. Several indicators tested were age, education, objectives ofrearing pigs, and species of pigs. The characteristics of pig farmers were similar. The variations of pigfarmers’ characteristics ware found in pigs’ rearing experience, animal number and litter size. Offeredfeeding on each physiological period was different. Similar finding were feeding sources and feedingprocess. Reproduction knowledge and their experience in farrowing management are similar amongstthe tribes. In general experiences and knowledge to prevent infectious diseases in general were similar.The three tribes have relatively similar in managing their pig farming systems.
