“…On the contrary, feed consumption was observed to increase along with body weight in a study on the effects of citric acid on phytate phosphorus utilization (Rafacz-Livingston et al, 2005). Similar results were also reported by Nezhad et al (2007) where the supplementation of citric acid in feed did not significantly affect feed intake in broilers. However, increased feed intake was reported in CA-fed broilers by Islam et al (2008) and Sharifuzzaman et al (2020).…”

The study was conducted to evaluate the effects of citric acid and mannanase feed supplementation on the growth performance of broiler chickens. Three hundred twenty day-old unsexed Cobb broiler chicks from a commercial hatchery plant were used in the study. The chicks were randomly assigned to four treatment groups following a completely randomized design. The following treatment groups were used: T1: Control, T2: 3% (w/w) Citric Acid supplementation, T3: 80 ppm β-Mannanase supplementation, and T4: 3% (w/w) Citric Acid and 80 ppm β-Mannanase supplementation. The supplementation of citric acid and mannanase significantly improves the growth performance of broiler chickens. Body weight and body weight gain were significantly higher (P<0.05) in the citric acid and β-mannanase combination group compared to all the treatment groups. The evaluation of feed intake revealed that T3 and T4 had significantly lower (P<0.05) feed intake than the other groups. The combination of citric acid and β-Mannanase also resulted in a significantly more efficient (P<0.05) feed conversion ratio. No mortality was observed during the experiment. It may be concluded that the supplementation of citric acid and β- mannanase resulted in a better performance in broilers.

An experiment was conducted to evaluate the effects of phytase (PHY), alone or in combination with citric acid (CA), on growing Japanese quails under moderate and severe phosphorus (P) restriction. For this, 504 one-day-old female quails were distributed in a completely randomised design with seven treatments and six replications. Treatments consisted of the following diets: (a) positive control (PC): formulated according to quails nutritional requirements; (b) negative control 40% (NC 40 ): PC with 40% less aP; (c) NC 40 +PHY; (d) NC 40 +PHY+CA; (e) negative control 65% (NC 65 ): PC with 65% less aP; (f) NC 65 +PHY; (g) NC 65 +PHY+CA. Phytase and CA were included at 300 FTU/kg and 40 g/kg, respectively. Performance, bone mineralization and plasma mineral concentration were evaluated at day 35; calcium (Ca) and P metabolism, between days 36 and 39. No significant differences in performance, plasma Ca and Pwere detected between quails fed PC or NC 40 ; however, NC 40 decreased tibia ash (p < 0.01). Treatment NC 65 impaired daily weight gain (p = 0.01), tibia ash (p < 0.01), and tibia optical densitometry (p = 0.03), as well as modified plasma Ca (p < 0.01) and P (p = 0.03) concentrations when compared to PC. Both NC 40 and NC 65 reduced P excretion (p < 0.01). Phytase alone restored tibia ash of NC 40 quails to regular rates. Nevertheless, only PHY and CA combined returned plasma P, tibia ash, tibia optical densitometry, and daily weight gain of quails fed NC 65 to similar values as those observed in PC. In conclusion, PHY alone suppresses the negative effects of moderate P restriction in growing Japanese quails, but fails in this task under severe P restriction. In such a situation, only the combination of PHY and CA ensures regular rates of growth and bone mineralization. This concept should be better explored by producers in order to take full advantage of the reduction in P excretion achieved by lowering dietary P concentrations.
