Abstract
ABSTRACT :
The present study was carried out to study the effect of inclusion of ajwain powder at varying levels on growth performance, serum biochemical profile, carcass characteristics and nutrient utilization in Japanese quails. One hundred and fifty day old quail chicks distributed randomly to five dietary groups each with three replicates of ten quails and were offered broiler quail diets to meet the nutrient requirements (NRC, 1994). During the experiment, ajwain powder is included at 0.0% (T1: Control), 0.25% (T2), 0.50% (T3), 0.75% (T4) and 1.0% (T5) level by marginal adjustment of other feed ingredients. All the rations were made iso-caloric and iso-nitrogenous. Chemical analysis indicated that ajwain powder contained 18.3% CP, 9.86% CF, 4.84% EE, 1.5% calcium and 0.3% phosphorus. Results indicated that inclusion of ajwain powder up to 1.0% level in the diet of Japanese quail had no effect (P>0.05) on body weight gains, feed intake and on feed consumed / kg gain. The serum biochemical profile of quails revealed that inclusion of ajwain powder up to 1.0% level in the diet had no effect (P>0.05) on serum total protein, albumin and globulin content in quails. Further, inclusion of ajwain powder in the diet had no effect (P>0.05) on serum glucose, triglycerides, total cholesterol, HDL, LDL and VLDL cholesterol content. Similarly, there was no effect (P>0.05) on serum calcium and phosphorous levels. However, the study indicated that the serum creatinine levels increased with increase in the level of inclusion of ajwain powder from 0 to 1.0% in the diet but the differences were not significant (P>0.05). The digestibility of DM, OM and NFE increased (P<0.01) with inclusion of ajwain powder at 0.25% in the diet as compared to the control. Further, inclusion of ajwain powder up to 1.0% level in the diet had no effect (P>0.05) on the digestibility of CP, CF, EE, NDF, ADF, hemi-cellulose and cellulose. However, inclusion of ajwain powder at 1.0% in the diet resulted in decreased (P<0.05) CP, NDF and cellulose digestibility as compared to 0.25% inclusion in the diet. Similarly, inclusion of ajwain powder up to 1.0% level in the diet had no effect (P>0.05) on percent nitrogen, calcium and phosphorous utilization as compared to the control. Furthermore, inclusion of ajwain powder up to 1.0% level in the diet had no effect (P>0.05) on carcass yield, dressing percent, ready to cook yield, meat to bone ratio, percent weight of heart, liver, gizzard and giblet in quails. The feed cost / kg gain decreased by 1.01 in T2 while it is increased by 4.11 in T3, 6.84 in T4 and 9.55 in T5 groups of quails fed diets containing ajwain powder up to 1.0% level as compared to the control. The study indicated that ajwain powder can be incorporated up to 0.25% level as natural feed additive in the diet of quails without any adverse effect on production performance.
