“…Also, Egila et al (2023) reported that during Japanese quail laying, antioxidants in diet impacted productivity, blood hematology, constituents, resistance, lipid digestion system, and antioxidative properties in serum and egg yolk. Ashour et al (2024) found that dietary energy and protein concentrations significantly affect digestion ratios in layer Japanese quail, suggesting a recommended energy content of 2,900 kcal metabolizable energy/kg with 20% crude protein.…”

Including dietary fat can increase the energy density of diets fed to ruminants, reducing dry matter intake (DMI). Effects of different fat sources on nutrient digestion and fermentation can vary depending on dietary fat concentration and the forage-to-concentrate ratio (F:C). Therefore, this study’s objective was to screen the effects of fat sources supplemented at different concentrations to high- and low-forage diets on in vitro digestibility and fermentation. Treatments included either low forage (LF; 35%) or high forage (HF; 70%) with two fat levels (6 or 9% DM) using six different fat sources, plus control. The control diet (CON) had a basal level of fat in the diet (3% fat; 0% fat inclusion), and fat sources were added to attain 6% or 9% dietary fat and consisted of the following: Coconut oil, CO; Poultry fat, PF; Palm oil, PO; Palm kernel oil, PKO; Soybean oil, SOY; and Ca Salts, MEG. In vitro Gas Production (GP) modules were randomly assigned to treatments in a 2 × 2 × 7 factorial design and were incubated for four 24 h runs. The CO-fed module had the highest dry matter (DM) apparent digestibility (AD) (p < 0.01), followed by SOY and PF. The true DM digestibility (TDMD) and organic matter (OM) AD were the highest in CO (p < 0.01) than the other fat types. The AD for DM, OM, neutral detergent fiber (NDF), and acid detergent fiber (ADF) was higher in LF (p < 0.01). The 6% fat inclusion had a higher GP (109 vs. 103 mL ± 2.09; p < 0.03). Total volatile fatty acid (VFA) concentration was lower in different fat types than the CON and the acetate molar proportion (p > 0.01). The propionate was the lowest for the CON, which increased the acetate to propionate (A:P) ratio (p < 0.01). These results suggest that LF diets with high fat concentrations can be utilized, and different fat sources may improve DM and fiber digestibility.

Quails are a valuable type of poultry, as their eggs and meat have high nutritional value. Moreover, quails are distinguished by early sexual maturity, high egg production and small body size. These unique characteristics make them an attractive object for breeding and scientific research. The purpose of the study was to investigate the effect of feed with extruded components and phytobiotics on the meat productivity and blood biochemistry of Texas quails. The methodology involved dividing 200 quails into experimental and control groups, feeding them different diets over a 60-day period, and analysing their growth performance, meat yield, and biochemical blood parameters using statistical analysis tools. As a result of the research, it was revealed that feed produced according to the developed recipe has a positive effect on the weight gain of quails. In the experimental group (EG), the absolute increase was 313.7 ± 4.34 g, in the control group (CG) – 275.9 ± 2.89 g (not significant difference, P > 0.05). Furthermore, the feed with extruded components and phytobiotics led to improved feed conversion ratio in the EG compared to the control. The birds in the EG also demonstrated higher carcass weight and yield. The experimental diet also appeared to have a positive influence on the immune status of the quails. The results demonstrate the potential benefits of incorporating extruded components and phytobiotics into quail feed to improve growth performance and maintain healthy physiological parameters. Evaluating the biochemical blood test results, it can be indicated that no significant changes in the blood composition were detected, which may indicate the absence of a negative effect of the developed feed on the body of birds. The results obtained may be of practical importance for developing optimal diets for meat quails and improving the quality and safety of their products
