Use of acetic acid and lactic acid as growth promoters and its effect on productive and physiological perfomance in different strain of quail

Abstract EN

This study was conducted to evaluate the responses of quail strains to acetic acid and lactic acid 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 bird were 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 2.5 mg acetic acid / kg ratio and the 3rd group was reared on standard ration supplemented with 2.5 mg lactic 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 gain and feed consumption were improved from the T2 food conversion factor and T3.

The results showed in the weight of the carcass at age 6 weeks in favor of T2 and T3 superior to T1, as well as weights of the back, thigh and chest.

The dressing percentage has exceeded T2 and T1 compared with T3 (P <0.05), which gave a lower percentage of them and gave the brown strain higher percentage of the black strain and the addition of organic acids improved the weight of the parts of liver and gizzard compared with T1.

The blood parameters were significantly higher for P <0.05 in RBC(Red blood), PCV(Packed cell volume), HB(Hemoglobin) and MCH(Mean corpuscular Hemoglobin) for the first treatment, while T1 and T2 were higher than T3 in MCV(Mean corpuscular volume) and MCH and the black strains scored higher than brown in RBC, PCV, HB and MHC.

(P <0.05) T1 and T2 on T3 in serum blood glucose and triglycerides.
