Abstract: The main target of this study was to determine the efficacy of acetic acid in improving the utilization of low protein-low energy broiler diets. In this study, a total number of 192 unsexed one day old Arbor Acres (FS) broiler chicks were distributed randomly and divided equally into eight experimental groups (4 concentrations of acetic acid each with one of two diets) nearly equal in average live weight. Each group was represented by birds in three replicate pens of 8 chicks each and kept under similar management conditions. Four concentrations (0, 3, 6 and 12%) of acetic acid were mixed daily with each of two diets at 20 ml / kg. The first diet (HP HE) contained the strain catalog recommendation of both energy and protein (23% CP and 3100 kcal ME /Kg from 0-3 weeks of age and 20% CP and 3200 kcal ME /Kg from 3-6 weeks of age), while the second diet (LPLE) contained low protein and low energy (21% CP and 2900 keal ME /Kg from 0-3 weeks of age and 18% CP and 3000 kcal ME/Kg from 3-6 weeks of age).
The results of this study showed that both strain catalog recommendation (HP HE) and acetic acid at concentration of 3 and 6% improved significantly (P<0.05) body weight (BW) and body weight gain (BWG) at 3 weeks of age. Improvement values in BWG due to addition of 3 and 6% acetic acid solutions to HPHE diets were 9.88% and 12.83% at 3 weeks of age respectively, while during the total period were 3.96% and 2.15%, respectively. Addition of same solutions to LP LE diets improved BWG only at 3 weeks of age by 3.98% and 2.65% as compared to the control of HPHE. Addition of acetic acid to either HPHE or LPLE diets increased the total amounts of feed consumed as compared to the control of HPHE diets. In general, there were no significant differences between the values of either total feed intake, feed conversion or viability due 10 acetic acid addition or the interaction between the diet and acetic acid concentration. Addition of acetic acid (at 3 and 6%) to HPHE or LPLE diets increased
liver and decreased bursa and thymus percentages. In addition, it improved the utilization of almost all the nutrients, increased blood calcium and decreased blood total lipids. Therefore, it is possible to suggest addition of 3 and 6% acetic acid solutions to either the strain catalog recommendation of both energy and protein (HPHE) or low protein and low energy (LPLE) diets at 20 ml/kg during the first three weeks of age to get the best broiler performance.
