They mature at an early age and the female birds are usually in full production by about 50 days of age, moreover quail meat has more protein than chicken meat. Its meat is very tasty and tender. It is fortified with nutrients required for human health and has a very low percentage of cholesterol More over quail meat has comparatively more protein percentage as compared to chicken meat and is a good source of certain B. vitamins. Sunflower (Helianthus annuus) oil meal is a by-product obtained after the extraction of oil from the decorticated sunflower seed. Being good source of vegetable protein (34% CP) the sunflower meal can be developed as a good vegetable protein supplement for different poultry rations. Sunflower meal is cheaper than soybean meal. It possesses high fiber content and chiorogenic acid an anti-nutritional factor, which can be reduce with the inclusion of enzymes. Kemzyme is stabilized multi-enzyme product from Kemin Europa NV, Belgium. It contains alpha - amylase beta - glucanase, lipase, protease, cellulase and hemicellulase complex including pentosanase, xylanase, pectinase and cellubiase. The enzyme mixture is claimed to break down the non-starch polysacchardies (NSP), reduces the viscosity of gut content and improves the utilization of feed nutrients,mainly cellulase and hemicellulase complex of Kemzyme by degrading high amounts of crude fiber in the sunflower meal. The present experiment was conducted to study the effect of enzyme (Kemzyme HF) supplementation on the nutritive value of diets containing different levels of sunflower meal on the performance of Japanese quails. Two hundred and seventy (270) day old quail chicks of mixed sexes were purchased from local hatchery and randomly divided into six groups of 45 quails each. Then each group was further subdivided into three replicates of 15 quails each and were kept in battery cages. Six isocaloric and isonitrogenous rations were prepared using three levels of sunflower meal viz., 5, 10, 15% without enzyme (Kemzyme HF) supplementation designated as A, B & C and with enzyme (Kemzyme HF) supplementation (500 g/ton) designated as D, E & F. The data on the weekly feed consumption and body weight recorded during the experiment. The total weight gain and feed consumption were used to calculate feed conversion ration and economics. At the end of the experiment three birds from each replicate were slaughtered to determine the dressing percentage. Proximate analysis of experimental rations were done according to AOAC (1984). The data collected was analyzed by applying analysis of variance technique using Least Significant Difference (LSD) test to detect the difference among the treatments and means, were compared by using least significant difference test. The results showed that the maximum weight gain (190 gm) feed consumption (515 gm), feed conversion efficiency (2.71) and dressing percentage (69%) were observed in the quails fed on ration E, containing 10% sunflower meal with enzyme supplementation. While the minimum weight gain (125 gm), lowest feed consumption (427 gm) poor feed conversion efficiency (3.41) and lowest dressing percentage (60%) were observed by the chicks fed on ration C containing 15% sunflower meal without enzyme supplementation. Economics of different experimental rations fed to birds with and without enzyme supplementation revealed that enzyme supplementation sunflower meal based diets increased the profit margin by the reduction in feed cost per unit gain. CONCLUSIONS On the basis of the results of present study the following conclusions may be drawn: 1. The optimum inclusion level of sunflower meal, without dietary modification in quail rations may be below 10 percent. 2. Enzyme (Kemzyme HF) supplementation can improve the weight gain, feed consumption, feed conversion ratio and dressing percentage and was the economical. 3. Enzyme (Kernzyme HF) supplementation of quail diets can only be feasible when sunflower meal used at 10 percent level.

The quail has gamed an important place in the poultry farming due to its better growth rate, less space requirement that is 8 or 10 quails occupy the same space on which a broiler can be reared. They mature at an early age and the female birds are usually in full production by about 50 days of age, moreover quail meat has more protein than chicken meat. Its meat is very tasty and tender.

Sunflower (Helianthus annuus) oil meal is a by-product obtained after the extraction of oil from the decorticated sunflower seed. Being good source of vegetable protein (34% CP) the sunflower meal can be developed as a good vegetable protein supplement for different poultry rations.

Sunflower meal is cheaper than soybean meal. It possesses high fiber content and chiorogenic acid an anti-nutritional factor, which can be reduce with the inclusion of enzymes.

Kemzyme is stabilized multi-enzyme product from Kemin Europa NV, Belgium. It contains alpha - amylase beta - glucanase, lipase, protease, cellulase and hemicellulase complex including pentosanase, xylanase, pectinase and cellubiase. The enzyme mixture is claimed to break down the non-starch polysacchardies (NSP), reduces the viscosity of gut content and improves the utilization of feed nutrients,mainly cellulase and hemicellulase complex of Kemzyme by degrading high amounts of crude fiber in the sunflower meal.

The present experiment was conducted to study the effect of enzyme (Kemzyme HF) supplementation on the nutritive value of diets containing different levels of sunflower meal on the performance of Japanese quails.

Two hundred and seventy (270) day old quail chicks of mixed sexes were purchased from local hatchery and randomly divided into six groups of 45 quails each. Then each group was further subdivided into three replicates of 15 quails each and were kept in battery cages.

On the basis of the results of present study the following conclusions may be drawn:

1. The optimum inclusion level of sunflower meal, without dietary modification in quail rations may be below 10 percent.

2. Enzyme (Kemzyme HF) supplementation can improve the weight gain, feed consumption, feed conversion ratio and dressing percentage and was the economical.

3. Enzyme (Kernzyme HF) supplementation of quail diets can only be feasible when sunflower meal used at 10 percent level.
