The Effect of Adding levels of Acetic and Citric Acids to Drinking Water on Indicators of Productive Efficiency of Broiler Chickens

Abstract

 The experiment was carried out at the College of Agricultural Engineering, within the design (CRD) On (225) hybrid birds from the Ross 308 randomly distributed into three treatments (control, treatment 1, treatment 2) (3*3*25). Citric and Acetic acids were added in combination, at two concentrations, the first (1.5, 1.5) and the second. (3, 3) ml, g/liter with the aim of determining their effect on indicators of production efficiency and carcass of broiler chickens. The results of the experiment showed that there was no significant effect (P>0.05) of adding organic acids on the live weight of birds treated (1,2) at the age of (1,2,3,4) weeks and at the age of (42) days, its effect was significant(P<0.05) on the birds of the treatments (1,2), and did not affect the weekly weight gain significantly(P>0.05), at the age of (6) weeks. Coefficients (1,2) on the control with significant differences(P<0.05).

The amount of feed consumed/g/week decreased in treatments (1,2) compared to the control, and at the age of (6) weeks, the amount of feed consumed increased in the birds of treatment 1 compared to the control and treatment 2, with significant differences (P<0.05). The addition of organic acids did not affect the feed conversion coefficient significantly(P>0.05) in weeks (1,2,3) and it improved in week (4) among birds treated (1,2) compared to the control, and the differences were significant between the control and treatment 1 (P<0.05) In week (6), the conversion factor of the treatment birds (1,2) improved compared to the control birds. The cumulative feed conversion factor improved in experimental birds (1,2) compared to the control, and the differences were significant between the first and the control (P<0.05)
