| Dissertation note | As the poultry industry flourished rapidly during the last thirty years, it has now become a major contributor in providing low cost protein of animal origin to our population. But unfortunately poultry industry is continuously suffering loses for the past few years mainly due the fact that the conventional feed stuffs are becoming costly day by day. The serious food shortage and increasing competition between human beings and poultry regarding the consumption of cereal grains demanded that cereals should be now spared for human consumption and exploration of non conventional feed sources should be carried out in order to keep the business of poultry industry running well. Rice polishing is a by-product of rice milling so it is abundantly available in Pakistan because rice is the third largest crop produced in the country. Rice polishing compares well with the cereal grains in chemical composition. So it contains more fat and protein as compared to maize but high in fiber contents. Due to high fat contents rancidity of Rice polishing can pose some problems if it is fed after prolonged storage, specially in hot weather. Extrusion cooking is a new technique which stabilizes the high fat diets and make them fit for use in the animal rations. For this reason full fat rice polishing was subjected to Extrusion Cooking which was done at National Feed Mill. Present Experiment was conducted to replace maize with extruded rice polishing and to see the effects on the performance of broiler chicks. Six starter and six finisher rations were prepared and designated as A, B, C, D, E and F . All rations were isocaloric and isonitrogenous. Starter ration and finisher ration A. were kept as a control containing 35 % Maize and 0% extruded Rice polishing, which was replaced by extruded rice polishing in ration B, C, D, E and F. on protein equivalent basis at 15, 20, 25, 30 and 35% level In this way a complete 100% replacement of maize with extruded Rice polishing was made One hundred and eighty day old chicks were randomly divided into eighteen experimental units of 10 chicks each. Each experimental unit was placed individually. The starter rations were fed up to 28th day of age while the Finisher rations from 29th to 42nd day of age. Results of the present study indicated that the weight gain up to 25% extruded rice polishing level was promisingly good. Maximum weight gain was recorded in Ration B (15% extruded rice polishing). Second best results were noted in the control ration but the performance of the chicks fed on 20% extruded rice polishing was almost equal to that of control ration. It was noted that the weight gain started to decrease gradually as the level was raised up to 35% of the total with each increasing increment. Best feed utilization was observed in the chicks fed on ration B, whereas poor utilization of feed was noted in higher levels of extruded rice polishing in the diet having more feed consumption compared to weight gain. Better performance up to 25% level indicated that Extrusion improved the nutritional quality of rice polishing by stabilizing it and inactivating Lipases. The extrusion also made starch more available for the birds and reduced the anti-nutritional elements of rice polishing. This is evident from the fact that the level of rice polishing effected the health of the chicks. It was therefore concluded from the present study that extrusion is an excellent technique for converting low quality feed stuffs into feeds with higher nutritional quality. Specially extrusion of low priced feed ingredients such as rice polishing and it replacement with a costly feed ingredient such as wheat or maize holds good economic prospects for feed millers. As extrusion is done on a very limited scale therefore after the present study it was strongly recommended that the use of extruded feed stuffs should be promoted in poultry ration |
