Performance, egg quality, and sensory analysis of the eggs of quails fed whole rice bran stabilized with organic acids and stored for different amounts of time

Abstract

Whole rice bran (WRB) was added to Japanese quail feed, and the effects of stabilization of the WRB with organic acids and its storage for different amounts of time were evaluated with respect to performance and egg quality, centesimal composition, and sensory characteristics. We used 150 90-d-old Japanese quails. We had a 5 × 2 factorial scheme of five storage periods (0, 30, 60, 90, and 120 d), with and without organic acid treatment. To replace corn, 20% WRB was added to the diet. Feed consumption increased for up to 71 d of bran storage (P = 0.01) and then subsequently decreased. An increasing quadratic relationship was observed between egg mass and storage time for up to 71 d of storage (P = 0.03); egg mass then decreased thereafter. The specific gravity of the eggs produced by birds that received treated WRB at 0 d of storage was greater than those of eggs produced by birds that received treated WRB after 90 d of storage. In conclusion, the organic acid treatment maintained the quality of the WRB over up to 120 d of storage and could comprise 20% of the laying quails' diet without affecting growth performance, egg quality, bromatological composition, or the sensory attributes of the eggs.Key words: egg quality, quails, whole rice bran, storage, sensory attributes.Résumé : Le son de riz entier (WRB) a été ajouté à l'alimentation des cailles du Japon et les effets de la stabilisation du WRB avec des acides organiques et son entreposage pendant des périodes de temps différentes ont été évalués par rapport à la performance et la qualité des oeufs, la composition centésimale et les caractéristiques sensorielles. Nous avons utilisé 150 cailles du Japon âgées de 90 jours. Un schéma factoriel 5 × 2 de cinq périodes d'entreposage (0, 30, 60, 90 et 120 jours), avec et sans traitement à l'acide organique. Pour remplacer le maïs, 20 % de son de riz entier a été ajouté à la diète. La consommation d'aliments a augmenté pendant 71 jours d'entreposage du son (P = 0,01), puis a diminué. Une relation quadratique croissante a été observée entre la masse de l'oeuf et le temps d'entreposage pendant jusqu'à 71 jours d'entreposage (P = 0,03); la masse de l'oeuf a diminué par après. La densité des oeufs produits par les oiseaux ayant reçu le son de riz entier traité à 0 jour d'entreposage était plus élevée que celle des oeufs produits par des oiseaux ayant reçu le son de riz entier traité après 90 jours d'entreposage. En conclusion, le traitement à l'acide organique a maintenu la qualité du son de riz entier pendant jusqu'à 120 jours d'entreposage, qui peut être utilisé à raison de 20 % de la diète des cailles pondeuses sans effet néfaste sur la performance de croissance, la qualité des oeufs, la composition bromatologique ou les caractéristiques sensorielles des oeufs.

Evaluation of the External and Internal Quality Characteristics of Quail Eggs Produced in Benghazi

“…(1986) and Moura et al, (2010) who observed that the specific egg weight was 1.054-1.081 and 1.074 g / cm 3 , respectively, and these differences can be attributed to strain, nutrition, age and method of measurement. Hrnar et al, (2014) found that the unit of egg whites in the Japanese quail-breed strain was 87.28, higher than the Haughunit and quail eggs in this study by 20.5%, the same increase observed by Gopinger et al, (2016) and Hassan et al, (2017). The deterioration in the quality of the yolk may be due to poor egg storage conditions after delivery, which causes the elasticity of the yolk membrane, its expansion and increase in its area, and in other words, the yolk diameter and then a decrease in the yolk guide.…”

Functional Quails Eggs using Enriched Spirulina during the Biosorption Process

“…Egg samples from each of the three periods were weighed before and after the oven drying at 60°C for 72 h and moisture content of the samples was calculated ( Gopinger et al, 2016 ).…”

“…Due to the direct effects of gamma-linolenic acid on the immune system and use in the treatment of many diseases, there has been a great interest in producing high concentrations of gamma-linoleic acid ( Andrade, 2018 ). Numerous studies have been done on the enrichment of quail feed with the use of S. platensis ( Boiago et al, 2019 ), lycopene ( Sahin et al, 2008 ), fish oil ( Kamely et al, 2016 ), vegetation such as liquor ice ( Doğan et al, 2018 ), and rice bran ( Gopinger et al, 2016 ), to enrich its eggs ( Wang et al, 2007 ). One of the side effects of using antibiotics is the formation of antibiotic resistance.…”
