Influence of Phytase with Or without Organic Acid (Sodium Di-Formate) Supplementation on Growth Performance, Carcass Response, Protein and Mineral Digestibility in Starter Phase of Broilers

Abstract

This experiment was planned to evaluate the effects of phytase supplementation with or without organic acid (OA) on performance, protein, calcium (Ca), phosphorus (P) and sodium (Na) digestibility and carcass parameters in broiler chickens fed low Ca and low P diets in comparison to a high Ca and high P diet with standard specifications. For this purpose, two iso-nitrogenous and iso-caloric diets were prepared in such a way that one diet had high Ca (9.80) and high P (4.50) and second diet had low Ca (8.50) and low P (2.40), respectively. Low Ca and low P diet was further supplemented with enzyme phytase @ 500 FTU/ kg, and phytase @ 500 FTU/kg + organic acid (1 kg/ton). Rations were offered to seven replicates of ten birds each, from day 1 to 21. Results revealed that the experimental treatments had no effect on feed intake and growth performance of birds (p>0.05). Carcass parameter results showed highest thigh meat yield % and liver weight % in the birds fed diet with low Ca & P and supplemented with enzymes phytase (p<0.05). Fecal P and Na digestiblities were high (p<0.05) in experimental broilers fed low Ca low P with enzyme phytase supplementation as compared to the diet without phytase supplementation. It is concluded that phytase and OA supplementation in the starter diet with low Ca and low P level did not influence intake, growth and feed conversion of the broilers. However, thigh meat yield percent and mineral digestiblities (P and Na) increased in the broilers that received the diet with low Ca and low P level and supplemented with enzyme phytase.

Gastrointestinal digestibility insights of different levels of coated complex trace minerals supplementation on growth performance of yellow-feathered broilers

“…During days 52 to 54, the broilers were fed an experimental diet and complete excreta were collected for 3 days ( 21 ). Excreta were collected thrice per day (07:00, 12:00, and 19:00 h) from each fecal tray under cages, weighed the weight of chicken excreta, mixed evenly, collected about 100 g of chicken excreta samples, and stored at −20°C.…”

A comparative study on the effects of fungal and bacterial phytase with or without citric acid on growth performance, serum mineral profile, bone quality, and nutrient retention in broilers

“…It was reported that organic acid decreases the pH of the broilers, and adding it to diets increases the effectiveness of added phytase [ 4 , 5 ]. Additionally, the synergistic effect of dietary phytase with citric acid (CA) was informed by several scientists [ 6 – 8 ].…”

Efficacy of bacterial phytase, citric acid and their combination in broiler fed inorganic phosphorus free diet

“…Considering these circumstances, it may be applicable to conduct research on broilers fed inorganic P free diets, but phytase. Several studies have been conducted using phytase in broilers diet, but in most cases, diets contained inorganic P (Ebrahimnezhad et al, 2008;Nezhad et al, 2011;Nourmohammadi et al, 2010Nourmohammadi et al, , 2012Mohammadagheri et al, 2016;Demirel et al, 2021;Anwar et al, 2022). Besides, organic acid such as citric acid (CA) is a well-recognized feed additive that is recently used in broiler diets to increase nutrient digestibility, mineral retention (Chowdhury et al, 2009;Islam et al, 2012) as well as enhance phytase activity (Vieira et al, 2018).…”
