The lack of locally available low-cost feeds and suitable feed making equipment to produce them has been identified as one of the major constraints limiting the development of small scale aquaculture in PNG. At the same time, the availability and cost of commercially manufactured feeds makes their use prohibitive. The supply and nutrient composition of local feed ingredients which are suitable for use in simple aqua-feeds is also extremely variable. Ingredient choice is also problematic, because while PNG farmers have access to many ingredients (mostly by- products), many of them are of low quality in terms of protein content, especially for. | Smallholder Poultry Production CHICKEN GENETIC RESOURCES USED IN SMALLHOLDER PRODUCTION SYSTEMS AND OPPORTUNITIES FOR THEIR DEVELOPMENT _____________________5 Smallholder Poultry Production CHICKEN GENETIC RESOURCES USED IN SMALLHOLDER PRODUCTION SYSTEMS AND OPPORTUNITIES FOR THEIR DEVELOPMENT PoulSorensen Department of Biotechnology and Genetics Faculty of Agricultural Sciences University of Ảrhus Denmark1 1 With support from Dr Mette H Hansen Department of Biotechnology and Genetics Faculty of Agricultural Sciences University of Ârhus Denmark FOOD AND AGRICULTURE ORGANIZATION OF THE UNITED NATIONS Rome .
