The Substitution Effect of Different Levels of Fish Meal with Shrimp Head Waste Meals by Soaking with Dusk Rice Husk Solution in Indigenous Chicken Diets

Abstract

209 The Substitution Effect of Different Levels of Fish Meal [ Mirzah] The objective of this study was to measure the effect of substituting different levels of shrimp head waste meals (SHW) for fish meal (FM) in indigenous chicken diets. FM is sole crude protein from animal sources. A control fish meal indigenous chicken diets and five different levels of SHW substituted for crude protein FM were fed to “ayam kampong” of 808 strains from day old chick to eight weeks of age. The crude proteins FM were replaced by 0 (R0); 25 (R1); 50 (R2); 75 (R3); and 100 (R4) percent of crude protein SHW. The five treatments were assigned to completely randomized design. Feed consumption, body weight gain, feed conversion, carcass percentage and income over feed cost were recorded to measure the perfor-mances. The results showed that feed consumption, body weight gain, feed conversion, carcass percentage and income over feed cost were not significant with the increasing level of SHW as substituted crude protein FM in indigenous chicken diets. However these parameters in bird fed 100 % SHW diets tended to decrease differ from those in bird fed 18.4 % FM (7.22 % crude protein from FM). The decreasing of performances may be due to the decreasing of feed intake and amino acid balance, and the increasing of the chitin contentഊin the diet. The conclusion of this experiment was that SHW can be used as a protein source in indigenous chicken diets up to 100 percent.
