    There are several important factors to be concerned when conducting a commercial piggery including feeding and housing. Feeding is one of the most important tasks based on meeting the animal’s requirements for energy and protein to optimize the growth performance and carcass lean content (Pettigrew and Esnaola, 2001). In general feed cost accounts for 55 % - 75 % of the total cost in any commercial pig farm (Ologhobo et al., 2012). As an alternative for high cost ingredients, some local feed that are inexpensive can be used in feed formulation for the fatteners which provide complete nutrition. Poultry Offal meal (POM) is one of the highly important feed stuffs available for the animal feed formulation (Hansen et al., 2006). Recycling of poultry offal waste helps to reduce the high cost of dietary ingredients and feeding that are associated with intensive animal production systems as well as to reduce the environmental and health hazards to human (Ologhobo et al., 2012). The objective of this experiment was to develop a ration with POM for feeding fattening pigs to reduce the cost of production and supply required level of nutrients. Methodology The current study was carried out at the Maxies & Company (Pvt) Ltd, Wennappuwa. One month old twelve fatteners were divided into four groups and fed with three experimental feed rations (Feed A, 23 % POM; Feed B, 20 % POM and Feed C, 18 % POM) and the commercial pig starter ration was given as the control feed for the fourth group. All three experimental feed rations were formulated with different proportions of POM and other ingredients as listed in Table 1., according to the swine nutritional recommendations of National Research Council (NRC, 1995).

    A Preliminary Study on Developing a Feed Ration with Poultry Offal Meal for Young Fattening Pigs
    (Uva Wellassa University of Sri Lanka, 2013) Perera, D.S.R.S.P.S.
    Twenty four young fattening Large white pigs at one month of age were selected from four litters born on same day, from same breed, reared under same environment, with same health conditions and mixed together and randomly divided into four groups (Experimental group A, B, C, and control) ensuring that each group contains three females and three males. The first three groups were fed with three treatments (Feed A, B, and C) of poultry offal meal (POM); 23%, 20%, and 18% respectively with other ingredients including maize, rice bran, wheat bran, and a premix of micro — macro ingredients and the control group with commercial pig starter for a period of nine weeks. The experimental feed rations (A, B, and C) were formulated ensuring that every feed ration provides the proper nutrient amounts recommended by NRC (2009) for the fatteners in tropical countries. Weekly body weight gaining was measured using a bridge scale (Farm MateTM, USA) along with the feeding program. Data were analyzed using non-parametric procedure (P<0.05). The study was conducted to develop a POM incorporated feed ration instead of the commercial pig starter for the young fattening pigs at 1 — 3 months of age and to determine the preferable inclusion of POM to formulate the least cost ration. The body weight gaining of all feeds were not significant (P>0.05) and the preferable and least cost ration with a 44.25% replacement profit of Rs.24.61 was the experimental ration B with POM inclusion of 20% when the cost of all feeds were compared.
