Effects of Organic Acids Supplement on Performance, Egg Traits, Blood Serum Biochemical Parameters and Gut Microflora in Female Japanese Quail (Coturnix coturnix japonica)

Abstract

This study was conducted to evaluate the effects of acetic acid, lactic acid, and butyric acid on the production performance, egg parameters (quality and quantity traits), blood and liver serum biochemical parameters and gastrointestinal tract microorganism on female Japanese quails. A total of 640 female Japanese quails aged 35-84 days were housedfor eight treatments with four replicates. They were arranged in completely randomized design (CRD) to evaluate the effects of basal diet (BD) with a supplement of acetic acid (AA), lactic acid (LA) and butyric acid (BA). The performance parameters to study this effect are feed intake, feed conversion ratio, egg traits such as egg weight, egg production, and egg mass along with specific gravity, internal quality unit (IQU), yolk and albumen indexes, and eggshell traits such as weight, thickness, and surface. It also includes blood serum biochemical parameters such as cholesterol, triglyceride, HDL, LDL, albumin, globulin, glucose, and gastrointestinal tract microflora (E.Coli and Salmonella). Eight dietary treatments were formulated by addition of organic acids such as BD without organic acids additive, BD with 124 mg/kg AA additive, BD with 104 mg/kg LA additive, BD with 113 mg/kg BA additive, BD with 63.5 mg/kg AA+53.5 mg/kg LA additive, BD with 63.5 mg/kg AA+57 mg/kg BA additive, BD with 53.5 mg/kg LA+57 mg/kg BA additive and BD with 41.6 mg/kg AA+35 mg/kg LA+37 mg/kg BA additive. The results showed that the diets containing BD+LA+BA+AA and BD+AA alone considerably increased feed intake, feed conversion ratio, egg weight, egg production and egg mass (p<0.01). The diets containing BD+AA and BD+LA significantly affected some quality traits such as eggshell thickness, eggshell weight (p<0.01), shell surface, and IQU (p<0.05). The diets containing BD+AA and BD+LA alone increased serum cholesterol, HDL, albumin, globulin and total protein significantly (p<0.01). Moreover, the groups containing BD+AA and BD+LA significantly decreased triglyceride contents in serum (p<0.05). The results showed that the diets containing BD+LA and BD+BA significantly decreased the E.Coli and Salmonella population in the gastrointestinal tract (p<0.01). Based on the experiment, it can beinferred that LA alone, or in combination with other organic acids, improved and showed positive effects on performance and egg traits in female Japanese quail.

Comparative Investigation of Egg Production in Wg, Gg and Gl Japanese Quail Populations

“…The analysis of the average laying intensity between production weeks 5-23 outlined with relatively stable egg production rates, showed statistically significantly higher values in group GL (88.98±0.54%), as compared to both meat-type populations GG and WG, with 82.87±0.86% and 80.36±0.60% respectively (p<0.001). Similar data for the egg production in Japanese quails were reported by Genchev and Kabakchiev (9), Genchev (2), Fouladi et al (10). Mori et al (11) published comparable yet higher values in meat-type quails, similar to those in our GL group.…”

“…In meat-type quails but with live body weight corresponding to the dual-purpose type (240-270 g), Santos et al (12) reported lower daily feed intake. Comparable results were also reported by Fouladi et al (10). Feed conversion ratio (FCR) is an important economic trait of efficiency of nutrients conversion into produce, herestock/breeder eggs.…”

Administration of Fermented Averrhoa bilimbi L. Fruit Filtrate on Growth, Hematological, Intestinal, and Carcass Indices of Broilers

“…With regard to the acids contained in the fermented fruit filtrate, organic acids may improve gut ecology, digestion, and absorption of protein and amino acids. The latter condition may thereby increase protein anabolism and thus increase lipoprotein synthesis (Fouladi et al, 2018), which is the major component of HDL. At both times of measurements, the increased levels of fermented fruit filtrate in drinking water were associated with increased serum ALT levels.…”

Egg Quality Traits in Wg, Gg and Gl Japanese Quail Populations

“…Analogous results were reported for this trait in several studies (9,13,16). Significantly higher yolk index values were obtained by Hanusová et al (10) in two Japanese quail population while a number of authorslower YI values (8,14,15,19,24). The trait related rather to consumers' attitudes than to egg quality is yolk colour, which also showed insignificant differences in the three groups.…”
