dc.description.abstract | A study was conducted to optimize the inclusion level of shrimp waste meal (SWM) as replacement for fish meal (FM) in broiler ration and to study the impact of feeding SWM on production performance and carcass characteristics of commercial broilers up to five weeks of age. A total of 300 day old straight run Cobb chicks belonging to single hatch were weighed and randomly allotted into five treatment groups with three replicates and each replicate had twenty chicks.The basal diet (T1) was prepared for broilers with the inclusion of 10% fish meal. The T2, T3, T4 and T5 diets were formulated by incorporating shrimp waste meal at 2.5%, 5%, 7.5% and 10% levels, replacing fish meal. Data on production performances like mean body weight, cumulative body weight gain ; feed consumption, feed conversion ratio and per cent livability, carcass yield, cut-up parts yield, proximate and fatty acid profile, HI titre against NDV and serum biochemical profile and economics were recorded. The data collected were subjected to statistical analysis and the results were interpreted. The results revealed that there was significant differences (P<0.01) in mean body weight and BWG among the treatment groups throughout the study period of five weeks. The treatment groups (T4 and T5) fed with higher inclusion level of SWM (7.5% and 10%) exhibited significantly (P<0.01) higher final body weight and BWG and comparable to T1 and T2, whereas T3 (5% FM + 5% SWM) recorded lowest values among the treatments. The mean cumulative feed consumption, FCR and per cent livability were not significant between the treatments. Carcass characteristics and carcass proximate composition did not differ significantly among treatments. There were significant (P<0.05) differences observed on stearic and behenic acids (saturated fatty acids) and palmitoleic acid (MUFA) in T3 (5% FM + 5% SWM) group; however, the other saturated fatty acids, MUFA and PUFA levels were not significant among groups. HI titre against NDV, the HDL: LDL and total cholesterol: HDL ratios were significant (P<0.05) and desirable values were obtained in T5 and T4 (10% and 7.5%) treatments and all other serum biochemical parameters were not significant between the treatments. The additional profit per kg body weight was more in higher SWM inclusion (T5-10% SWM and T4-7.5% SWM) groups when compared to higher FM included (T1 and T2) groups and was lowest in T3 (5% FM+ 5% SWM). The 7.5% SWM (T4) treatment group performed well in terms of broiler economic indices with higher returns and was comparable to T5 (10% SWM) group. | |
