Aim: The objective of this study was to evaluate the effect of feeding fermented fish silage (FFS) on serum biochemical parameters of Japanese quails (Coturnix coturnix japonica).
Materials and Methods: A total of 192, 7-day-old broiler Japanese quail chicks of either sex, were randomly distributed into four dietary treatments with four replicates in each group having 12 chicks in each replicate pen. The dietary treatments were T1 - Control diet, T2 - Diet containing 5% FFS, T3 - Diet containing 10% FFS, and T4 - Diet containing 15% FFS. Group body weight and feed consumption were recorded at weekly intervals. Feed conversion ratio (FCR) was derived by dividing the feed consumed with the weekly body weight gain. At the end of the experiment, 8 birds from each treatment were selected randomly and sacrificed by cervical dislocation to study the carcass traits expressed as % pre-slaughter live weight. At 5 weeks of age, about 2 ml of blood was taken from the jugular vein of each selected bird, and serum samples were separated after centrifugation. Total protein, albumin/globulin (A/G) ratio, calcium, phosphorus, triglyceride, total cholesterol, high density lipoprotein-cholesterol (HDL-C), very low density lipoprotein-cholesterol (VLDL-C), low density lipoprotein-cholesterol (LDL-C), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were estimated in the serum.
Results: The cumulative body weight gains from 1 to 5 weeks of age did not vary significantly between control and 5% FFS group. However, a linear decrease in body weight gain was observed by increasing the levels of FFS beyond 5% in the diet. The cumulative feed consumption was significantly higher in case of birds under control group during 1-5 weeks of age as compared to birds fed FFS based diet (5%, 10%, and 15%). No statistical difference in cumulative feed conversion ratio could be noticed during 1-5 weeks of age. The eviscerated yield decreased and giblet weight increased due to the dietary supplementation of FFS at 15% level. The breast meat yield decreased due to dietary supplementation of FFS at 10% and 15% level in the diet of broiler Japanese quails. The effect of FFS was found to be nonsignificant (p>0.05) with respect to serum total protein, globulin and A/G ratio under different treatments whereas significant difference observed in serum albumin concentration. Dietary supplementation of FFS at 10% and 15% level significantly increased the AST concentration in serum. There was no significant difference among the treatments regarding the parameters such as ALT, calcium, phosphorous, triglyceride, total cholesterol, HDL-C, VLDL-C, and LDL-C.
Conclusion: The serum-biochemical parameters are influenced by the dietary supplementation of FFS in broiler Japanese quails.
