USE OF ACETIC ACID AND LACTIC ACID AS GROWTH PROMOTERSAND ITS EFFECT ON PRODUCTIVE AND PHYSIOLOGICALPERFOMANCE IN DIFFERENT STRAIN OF QUAIL

This study was conducted to evaluate the responses of quail strains to acetic acid and lacticacid supplementation on some productive and physiological parameters . 126 quail (1 day old)divided 63 birds from brown strain and 63 bird from black strain were used in the study. The birdwere divided into 3 groups 42 birds /group, 3 replicates 14 birds/replicate), The 1st group (control)was reared on standard ration , the 2nd group was reared on standard ration supplemented with 2.5mg acetic acid / kg ratio and the 3rd group was reared on standard ration supplemented with 2.5 mglactic acid / kg ratio . the treatment continued for 6 weeks. The results showed that T2 and T3 (P 0.05) were superior to the T1 in live body weight at the age of 1 week and 5 weeks, the weight gainand feed consumption were improved from the T2 food conversion factor and T3. The resultsshowed in the weight of the carcass at age 6 weeks in favor of T2 and T3 superior to T1, as well asweights of the back, thigh and chest. The dressing percentage has exceeded T2 and T1 comparedwith T3 (P 0.05), which gave a lower percentage of them and gave the brown strain higherpercentage of the black strain and the addition of organic acids improved the weight of the parts ofliver and gizzard compared with T1. The blood parameters were significantly higher for P 0.05 inRBC(Red blood), PCV(Packed cell volume), HB(Hemoglobin) and MCH(Mean corpuscularHemoglobin) for the first treatment, while T1 and T2 were higher than T3 in MCV(Meancorpuscular volume) and MCH and the black strains scored higher than brown in RBC, PCV, HBand MHC. (P 0.05) T1 and T2 on T3 in serum blood glucose and triglycerides.
