Development of Poultry Sausages Utilizing Manually and Mechanically Deboned Meat from Spent Laying Quails

The growth in quail egg production presents opportunities to utilize spent laying quail meat in value-added products, thereby enhancing the poultry industry. This study aimed to develop and evaluate sausages made with quail breast meat (QBM), chicken breast meat (CBM), mechanically deboned quail meat (MDQM), and mechanically deboned chicken meat (MDCM). The poultry breast and deboned meat samples were characterized and used to prepare five sausages (S1 = 100% CBM, S2 = 100% QBM, S3 = 60% CBM + 40% MDQM, S4 = 60% QBM + 40% MDCM, and S5 = 50% MDCM + 50% MDQM). QBM exhibited a higher protein content (25.26%) than CBM (22.33%), while MDQM contained higher collagen (1.23%) and ash (3.78%) contents than that of MDCM. MDCM displayed a darker (lower L*), redder (lower h), and more intense (higher C*) color than MDQM. Sausages containing mechanically deboned poultry meat (S3, S4, and S5) exhibited a more yellowish (h = 62.9°) tone compared to those containing only breast meat (h = 56.2°). S4 sausages exhibited the highest sensory acceptability (score 7.2), whereas S5 sausages, described as having a dark, non-uniform appearance and sandy texture, were less preferred (score 5.1). These findings highlight the potential of spent quail meat in sausage production, offering a promising avenue for product innovation and market expansion.

Effects of Dietary Resveratrol and Black Soldier Fly (Hermetia illucens) Larvae Meal Supplements on Quail Egg Production, Quality, and Consumer Acceptance.

This study aimed to examine the effects of supplementing a basal diet with resveratrol and black soldier fly (Hermetiaillucens) larvae meal on Manchurian Golden quail egg production and quality as well as consumer attitudes towards the quail eggs and their acceptability. Quail were allotted three treatments for a laying period of 3 months. The dietary treatment groups were those of a basal diet, a basal diet with 250 mg/kg resveratrol pliusACE, and a diet supplemented with 10% black soldier fly larvae meal (BSF). The BSF larvae meal supplement increased the live weight of the quail, but the differences in the mean egg production and egg external parameters between the experimental groups were insignificant. The egg yolk from the quail fed with resveratrol and BSF supplementation demonstrated lower (p < 0.001 and p < 0.01) pH compared with the quail fed a basal diet. Egg yolk colour showed lower (p < 0.05) lightness and lower (p < 0.01) yellowness and colour saturation in the group of quail fed with resveratrol supplement compared with BSF supplement. Resveratrol inclusion in the basal diet resulted in increased (p < 0.001) protein content in the yolk. BSF inclusion in the diet showed the effect by increasing (p < 0.001) dry matter in albumen. The total monounsaturated fatty acids, polyunsaturated fatty acids, and cholesterol content were not affected by the dietary treatment. The inclusion of BSF larvae meal in the diet increased the proportion of total saturated fatty acids and lowered the proportion of total trans fatty acids in yolk lipids and demonstrated less favourable ratios of fatty acids and nutritional indices, except for the peroxidisability index, and showed higher oxidative status (p < 0.05), flavour score, and overall egg acceptance compared with the quail fed on a basal diet.

Effects of Dietary Schizochytrium Algae as ω-3 PUFA Source on the Egg-Laying Quail Performance, Serum Indexes, and Egg Yolk Fatty Acids Contents.

The objective of this experiment is to investigate the effects of SAP or SAO as ω-3 PUFA raw materials on production performance, egg quality, serum immunity, serum lipids, and fatty acid deposition patterns in the eggs of laying quails. Chinese yellow-feathered quails served as the experimental subjects. A single-factor design was employed to randomly assign 1288 quails into four treatment groups, with seven replicates per treatment and 46 birds in each replicate. The groups included a control group (basal diet with no SAP), 1.6% SAP, 3.2% SAP, and 0.8% SAP + 0.3% SAO. The results indicate that: (1) Compared to the control group, the 0.8% SAP + 0.3% SAO group exhibited a reduction in daily egg-laying rate and egg mass, alongside an increased FCR; (2) the 3.2% SAP group enhanced egg yolk color, while the 1.6% SAP group reduced eggshell thickness, and the 0.8% SAP + 0.3% SAO group increased eggshell thickness; (3) compared to the control group, the 3.2% SAP group decreased total cholesterol (TC) and high-density lipoprotein cholesterol (HDL-C) levels in serum; the addition of either the 3.2% SAP or the 0.8% SAP + 0.3% SAO group significantly elevated quail serum immunoglobulin M (IgM) levels (p < 0.05); (4) in comparison to the control group, the addition of SAP or with SAP increased the contents of monounsaturated fatty acids (MUFA), polyunsaturated fatty acids (PUFA), docosahexaenoic acid (DHA), and ω-3 PUFA in 56-day-old egg yolks while reducing the ω-6/ω-3 ratio (p < 0.05). These findings suggest that SAP as a source of ω-3 PUFA raw materials could improve quail health by improving lipid metabolism and immunity. 3.2% SAP was recommended as the optimal level to produce the enriched ω-3 PUFA quail eggs with the ω-3 PUFA ≥ 300 mg/100 g.

Effect of Thermal Manipulation During Embryogenesis on Pre and Post-Hatch Performance of Stored Hatching Eggs of Japanese Quails

This research investigated the influence of high incubation temperature on hatching, and post-hatch characteristics of stored hatching eggs of Japanese quails. Hatching eggs of Japanese quails were stored for 7 days and incubated under two temperature conditions. The T1 group (control, 75 eggs) was subjected to a standard incubation temperature (37.5°C) while the T2 group (75 eggs) was exposed to a thermal manipulation protocol (of 38.5°C for 5 hours daily between embryonic days 5-15. The egg weight classification, chick weight, chick length, wing length, weekly body traits, body weight, total feed intake, and stress responses, weight of internal organs, whole carcass, breast, neck, wing, thigh, and neck did not significantly differ (P&lt;0.05) between the incubation treatments. Hatchability was higher and early embryonic mortality was lower in T2 than in T1. Late embryonic mortality was lower in T1. Significantly (P≤ 0.05) higher pectoral muscle width at hatch and carcass yield/dressing percentage were observed in quails exposed to thermal manipulation protocol during embryogenesis. It was concluded that exposure of stored eggs to thermal manipulation protocol (of 38.5°C for 5 hours between embryonic days, ED 5-15, T2) during embryogenesis could enhance embryonic and growth traits, as well as carcass traits without any negative effect on stress indicators.

Price fluctuations of quail eggs at the farm level and their contributing factors in The Jabodetabek and East Java

Quail eggs offer numerous health benefits, including enhancing the immune system, supporting brain growth and development, and repairing damaged cells. Indonesia has key quail egg production centers in East Java, with the Jabodetabek area serving as the primary consumer market. This has led to price disparities between the two regions at the producer level. From October 2023 to September 2024, the average price of quail eggs at the producer level in East Java was IDR 30,738 per kg, while in the Jabodetabek area, it was IDR 32,738 per kg. The highest prices in both regions were recorded in May, with the lowest prices observed in December. In May, the price of quail eggs in Jabodetabek reached IDR 36,000 per kg, while in December, it dropped to IDR 22,000 per kg. In East Java, the price in May was IDR 34,000 per kg, and in December, it decreased to IDR 20,000 per kg. The most significant price fluctuations in Jabodetabek occurred in February, with a coefficient of variation (CV) of 0.739, while in East Java, the highest fluctuations were recorded in both November and February, with a slightly higher CV of 0.740.

The influence of using fermentated rumen content at quail feed to the protein of yolk and albumen of quail eggs

Ruminal content is one of slaughterhouse waste that has not been utilized optimally, in fact there are cases where ruminal content are thrown away haphazardly, causing environmental pollution. The nutritional value of ruminal content is relatively high which is caused by the imperfect nutrition absorption do not have much difference with the original nutritional value coming from the cattle feed itself. nutritional value in ruminal content is 8.86% of protein, 2.6% of fat, 28.78% of fiber, 0.55% of phosphor, 18.54% of ash and 10.92% of water content. The aims of this research was to find out whether the usage of fermentation cattle ruminal content in quail’s feed ransom can influence the protein content inside the yolk and albumen of an egg. This research used fermentation cattle ruminal content and divided into four treatments. The first treatment (T0) was only giving formula feed. The second treatment (T1) was Formulation feed (5% fermentated rumen content). The second treatment (T2) was Formulation feed (10% fermentated rumen content). The third treatment (T3) was Formulation feed (15% fermentated rumen content). The experiment design was Completely Randomized Design.

Potential of fermented rumen content of cow feed on daily egg productivity and quality of yolk color of quail egg (Cortunix cortunix japonica)

The purpose of this study was to determine the effect of fermented rumen contents on quail rations. The parameters measured were daily egg production and egg yolk quality. There are 96 quails with 4 treatments and 6 repetitions. (T0) formulation feed without fermented rumen contents, (T1) formulation feed + 5% fermented rumen content, (T2) formulation feed + 10% fermented rumen content, (T3) formulation feed + 15% fermented rumen content. Samples are observed daily for daily egg production and the last week for egg yolk quality. The results showed that the uses of fermented rumen contents in rations at a rate of up to 15% causeddid not interfere towards daily egg production and could even improve the quality of egg yolk.

Manifestation of the FLASH effect in proton irradiation of embryos

Purpose In order to study the FLASH effect using live models, this work compared proton-induced damage to embryos (nine days after fertilization) and one-day-old chicks (18 days after fertilization) from irradiated at different dose rates eggs of Japanese quail (Coturnix coturnix japónica). Materials and methods Eggs were irradiated with protons in different modes depending on the dose rate: in a conventional mode (<1 Gy/s, CONV), in a flash mode (∼100 Gy/s, FLASH) and in a single-pulse flash mode (∼105 Gy/s SPLASH). Results By the criteria of body weight and length, as well as the number of erythrocytes with micronuclei in nine-day-old embryos from eggs irradiated in the spread-out Bragg peak (SOBP) (8.5 Gy), FLASH and SPLASH modes were found to be less traumatic compared with the CONV mode. Among all irradiated embryos, the maximum body weight and length were observed in the SPLASH mode. The lowest death incidence and the smallest number of abnormal erythrocytes were recorded after FLASH and SPLASH irradiation. In chicks that hatched from eggs irradiated in the CONV mode, a tendency for an increase in the number of abnormal erythrocytes was observed. The speed of movement of chicks from FLASH- and SPLASH-irradiated eggs was comparable with that from unirradiated eggs, while chicks from eggs irradiated in the CONV mode were less active than all others. Conclusions The proton irradiation of eggs in SOBP using high dose-rate modes is less damaging for healthy tissues and for the development of embryos and chicks on the cellular, anatomical, and physiological levels.

Evaluation of black soldier fly larvae oil (Hermatia illucens L.) calcium salt as an alternative fat source for laying quail diets.

This study aims to determine the effect of adding saponified black soldier fly larvae oil calcium salt (BSFLO-SCa) to quail feed as an alternative source of fat on laying performance, blood lipid profile, egg quality, and gene expression in lipid metabolism. A total of 120 female Japanese quails (Coturnix japonica) aged 24 weeks were divided into 3 treatments, each with 8 replications, and each replication consisted of 5 quails in a completely randomized design. The applied treatments were the inclusion of basal feed as a control (T0) and basal feed supplemented with 1% BSFLO-SCa (T1) and 2% BSFLO-SCa (T2). The study indicated that the supplementation starting from 1% of BSFLO-SCa significantly decrease (p<0.05) in feed conversion ratio (FCR), blood lipid profile (total cholesterol, LDL-cholesterol). Gene expression on fat synthesis of fatty acid synthase (FAS) and cholesterol synthesis of 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGR) downregulated (p<0.05). In addition, the other parameters did not affect by supplementation of 1% BSFLO-SCa. The inclusion at 2% of BSFLO-SCa significantly increased (p<0.05) protein content of yolk and albumen, egg weight, egg shape index, and gene expression on fat oxidation of carnitine palmitoyltransferase-1 (CPT-1). Egg yolk cholesterol, egg albumen ash, haugh unit (HU), and gene expression on fat synthesis of acetyl-CoA carboxylase (ACC) were significantly reduced (p<0.05). Addition of 2% BSFLO-SCa in the feed improves performance, egg quality, and reduces cholesterol in the blood and eggs of quail. This improvement is accompanied by a reduction in the expression of key genes involved in lipid metabolism. BSFLO-SCa oil has the potential to be an alternative oil source in quail feed.

Influence of storage periods of quail eggs of Radonezh breed on the results of incubation and the development of young poultry

The storage period of eggs has a negative influence on the incubation period, embryo development, egg hatchability and hatching of young animals, which ultimately reduces the economic efficiency of the poultry farm. In breeding quail farms, the collection period of hatching eggs can reach 2–3 weeks. Our studies have studied the infl uence of the storage period of hatching eggs on the duration and results of incubation, the development of young quails. These issues have been studied not enough in meat-productive quails. In Russia, similar studies have been conducted on egg-productive quails of Japanese gray breed. However, poultry with meat productivity differs in both the duration of incubation and its results due to differences in metabolism in the body. Research has been carried out at the Siberian Research Institute of Poultry Farming on the eggs of Radonezh quail breed. It has been established that storing quail eggs for more than 7 days reduced the capacity of egg hatchability by 3.3–29.0 abs.%, and the hatching of young animals by 6.2–36.5 abs.%. Extending the shelf life of quail eggs to 14–21 days increased the average incubation hour by 2.5–9.7 hours, had a statistically signifi cant infl uence during embryogenesis on the live weight of day-old quails, the use of nutrients in the yolk sac and the development of the heart, liver and muscular stomach. It is advisable to store the hatching eggs of meat-productive quails of Radonezh breed before incubation for no more than 7 days. The results of these research can be used in breeding, industrial and farm quail farms for planning the sampling time, the number of eggs laid for incubation and places for planting day-old young animals, the population of future layers, and the volumes of necessary feed.

COMPARATIVE CHARACTERISTICS OF FOOD EGGS

The most commonly consumed poultry eggs in the world are chicken and duck eggs. Eggs contain all the essential amino acids, making them an excellent source of complete protein. Egg whites, both chicken and duck, are similar in composition and have many functional properties.The purpose of this work is to comparatively characterize the chemical composition and quality characteristics of commercially available eggs of various types produced in Kazakhstan. The work used generally accepted chemical and physical methods of determination, as a result of which it was established that all types of eggs differ in quality characteristics and chemical composition. The experiments carried out established that duck eggs have the largest mass (79.49 g). Egg white has an alkaline pH, while the yolk has a neutral pH. The highest water content is found in chicken protein (87.7%), duck eggs have a high lipid content - 36.79%, and the highest ash content in quail eggs – 1.8 g.The results of the research will be used in the development of egg products from raw materials that must meet the requirements of the standard.

Development of an Enhanced Quick, Easy, Cheap, Effective, Rugged, and Safe Method for Determination of Quinolone Drug Residues in Quail Eggs

ABSTRACTAn enhanced quick, easy, cheap, effective, rugged, and safe (QuEChERS) purification method utilizing multi‐walled carbon nanotubes (MWCNTs) has been developed and coupled with liquid chromatography‐tandem mass spectrometry for the determination of eight quinolone drug residues in quail eggs. The sample was extracted using ethylenediamine tetraacetic acid‐McIlvaine buffer (pH = 4.0) and 2% formic acid in acetonitrile, followed by salting out with MgSO4, and purification with primary secondary amine (PSA), MWCNT, and Octadecylsilane (C18). The method demonstrated linear relationships for the target compounds within the range of 2–100 µg/L with correlation coefficients (r) exceeding 0.99. The limits of detection and quantification were determined to be 0.4 and 0.8 µg/kg, respectively. Validation through a three‐level spiking test (low, medium, and high) in quail eggs resulted in an average recovery rate ranging from 86.8% to 113.7%, with relative standard deviations between 2.6% and 10.2% (n = 6). This method offers rapid operation, excellent purification efficiency, and high sensitivity, making it suitable for the qualitative and quantitative analysis of quinolone drug residues in eggs. Application of this method to a batch of 20 quail eggs revealed the presence of enrofloxacin and ciprofloxacin, suggesting a potential risk of non‐compliant quinolones use in quail egg production.

Transparent mechanism of salted egg (white) hierarchically and synergistically driven by NaCl, NaOH and thermal treatment: Based on empirical data and molecular simulation

Currently, it is a challenge that the yolk in salted preserved egg tends to preserved egg yolk due to extreme NaOH treatment. Therefore, NaCl, NaOH and thermal were successfully used to prepare a new translucent salted quail egg (T-SQE), which combined advantages of preserved egg white with transparent appearance and salted egg yolk with unique texture and odour. Moreover, transparency of opaque gel (Transmittance: 0.09 %) subjected to NaCl and thermal was demonstrated to be improved under the synergistic effect of NaOH (8.55 %) via empirical data and molecular simulation. The disordered and dense network in opaque T-SQE induced by NaCl and thermal tended to form an ordered, porous and transparent structure in presence of NaOH, with more immobilized water that was poorly bonded to protein, larger radius of gyration and lower hydrophobic interaction. This research provides new insight into understanding the influence of hierarchy and synergism on transparency of egg products.
