Natural acids are powerless and can't be totally isolated and the majority of these acids have antimicrobial action [1]. Natural acids were chosen as promising food added substances in poultry creation because of their capacity to keep up with the trustworthiness of the gastrointestinal cell layer, diminish the quantity of destructive microorganisms, work on the pace of processing and food retention and add to working on useful execution [2,3]. Concentrates on natural acids affirmed that blending at least two natural acids works on the useful execution and resistance of birds better compared to any corrosive added to the eating routine alone [4].

Citrus extract is quite possibly of the most broadly consumed natural corrosive on the planet, which has prompted a colossal business interest in it as well as prodding researchers to find new predominant creation strategies [5]. Citrus extract (CA) is a Krebs-cycle corrosive with a chain of six carbon particles (C6) found by the Swedish scientist Carl Wilhelm Scheele in 1784 through his crystallization of lemon juice [6]. CA's name comes from the Latin word citrus, a tree got normally from citrus products of the soil [7].

CA and its salts assume a significant part in energy digestion PP keeping up with gastrointestinal homeostasis and epithelial honesty, taking part in the safe reaction, decreasing aggravation and diminishing oxidative pressure in poultry [8-11].

Citrus extract (CA) is a feeble natural corrosive that makes different antibacterial impacts, contingent upon the pKa worth of the corrosive and the gastrointestinal pH [12], that cause the demise of unsafe microorganisms in the stomach of creatures [13]. What's more, the antibacterial movement of CA makes an acidic state in the stomach (pH 3.5-4.0), which represses the development of Salmonella Escherichia coli and other corrosive prejudiced Gram-negative microorganisms in the gastrointestinal system of birds [14]. Its component of activity is by actuating proteolytic proteins and decreasing the gamble of disease [15].

This study was directed in the field of poultry in the Division of Creature Creation/School of Farming/College of Diyala for the period from 10/1/2022 to 11/4/2022 for a time of 35 days. The impact of adding sodium citrate to water on the useful and physiological execution of grills has been considered.

In the examination, 405 unsexed, one-day-old 308 Rose chickens were utilized, haphazardly dispersed to nine medicines, with three replications for every treatment, with three distinct densities and the utilization of two unique centralizations of sodium citrate. The medicines are as per the following:

• T1: It was benefited from a standard eating regimen and normal water at a thickness of 12 fowl/m2

• T2: They were benefited from a standard eating regimen and water to which 1.5 g/l of sodium citrate was added, at a thickness of 12 birds/m2

• T3: They were benefited from a standard eating routine and water to which 3 g/l of sodium citrate was added, at a thickness of 12 birds/m2

• T4: Control treatment and benefited from standard eating routine and normal water at a thickness of 15 birds/m2

• T5: They were benefited from a standard eating regimen and water to which 1.5 g/L of sodium citrate was added, at a thickness of 15 birds/m2

• T6: They were benefited from a standard eating routine and water to which 3 g/l of sodium citrate was added, at a thickness of 15 birds/m2

• T7: Control treatment and benefited from standard eating regimen and ordinary water at a thickness of 18 birds/m2

• T8: It was benefited from a standard eating regimen and water to which 1.5 g/l of sodium citrate was added, at a thickness of 18 birds/m2

• T9: They were benefited from a standard eating regimen and water to which 3 g/l of sodium citrate was added, at a thickness of 18 birds/m2 (Table 1)

A factorial experiment using Complete Randomize Design (CRD) in analyzing the data between the treatments. Significant differences between the means of the treatments were measured using the Duncan test at the level of significance of 0.05. The ready-made statistical program SAS [16] was used to analyze the data.

Microbial Traits

One gram was taken from the jejunum of each bird of the three slaughtered birds for each treatment at the age of 35 days and it was added to the physiological saline solution in a volume of 9 mL under sterile conditions and decimal dilutions were made from it up to a dilution of 5-10 to estimate the numbers of the following bacteria:

• Total bacteria preparation

• Preparation of E. coli bacteria

• Preparation of Lactobacillus bacteria

The Spread Plating Method was used according to the method of Samanta et al. [17], by using Nutrient Agar to estimate the number of total bacteria, Mac Con Key Agar to estimate the number of coliform bacteria and MRS Agar to estimate the number of lactic acid bacteria, through transfer 0.1 mL of each decimal diluent by a sterile pipette (Micropipet) into each two dishes of Petri dishes prepared in advance from the special culture medium for each of them and spread on the surface of the solidified medium by means of a sterile hooked glass rod resembling the large letter L, then the special dishes were incubated for total aerobic bacteria and bacteria coli in an inverted manner at 37°C for 24 hours, while the dishes for lactic acid bacteria were incubated upside down and away from air at a temperature of 37°C for 48 hours and the growing colonies were counted in each of the three media, by selecting a culture plate that is good for growing the number of colonies from each two dishes for each  decimal dilution and the numbers of colony forming units (cfu) were calculated and multiplied by the inverse of the dilution to obtain the number of bacterial colonies per gram of the fasting sample and the concentrations of these bacteria were converted to logarithmic numbers to the base (10) and expressed as log 10 and mt/g.

From the results of the beneficial qualities in this review, it is noted that the expansion of sodium citrate, whether in feed or water, mainly affected its improvement and the justification for this improvement may be that the expansion of natural acids tries to reduce the pH in the frame related to the stomach, which gives a reasonable climate To formulate pepsin catalyst and thus expands the dissociation of proteins into amino acids, which leads to more advanced processing and retention of supplements, attempts to keep up the credibility of films and the wall of the gastrointestinal tract, increase profitable microorganisms and achieve microbial balance and improve the rate of digestion and absorption of nutrients and thus contribute to the improvement of productive performance for poultry [2,19-24].

When birds are fed organic acids, this leads to a decrease in the pH of the gut of poultry, which reduces pathogenic bacteria and improves gut morphology and microbial balance. In this way, further development of the assimilation limit of enteric supplements in the gastric framework, further development of gastrointestinal processing and retention, expansion of the amount of supplement consumed [25,26] and the addition of Sodium Citrate (SC) in the diet of birds domestic animals has strong antibiotic effects. Oxidative stress inhibits many harmful microorganisms [27]. The end result is an improved productive performance of the organic acid-fed birds.
