The objective of this study was to evaluate the inclusion of powder cinnamon in the diet of Japanese quails, regarding their performance and egg quality. A total of 360 quails, 18 weeks old, were distributed in a completely randomized design with five treatments and six replicates of 12 animals. The experimental period lasted 84 days. The treatments were the inclusion of 0; 3.0; 6.0; 9.0 and 12.0 g kg-1 of cinnamon powder in the diet. The performance and quality of eggs produced were evaluated. A sensorial analysis of the eggs was carried out to evaluate the color of the egg yolk, the taste of the egg and the purchase intention. There was no significant effect on the performance and egg quality variables, except for the specific gravity and color of the yolk, which increased linearly. The evaluators presented a higher intention to purchase eggs from the treatment with 6g kg-1 of cinnamon addition in the diet. We concluded that the inclusion of 12.0 g kg-1 of cinnamon powder in the diet for laying quail does not affect the performance and the taste of the eggs, nevertheless, this level of inclusion provides an improvement in the specific gravity and color of the yolk.

Abstract The study was carried out in the poultry field of the Animal Production Department of the Faculty of Agriculture at Tikrit University. The current study aimed to estimate the effects of adding different percentages of octacosanol, wheat germ oil and rice oil to the ration on egg quality traits. 96 laying quail (age 45 days), were used and divided into six treatments were included: adding the octacosanol/kg feedstuff (T1 without adding, T2=15 mg, T3=20 mg, T4=25 mg), (T5) was adding 5 ml of wheat germ oil/kg feedstuff and (T6) wasadding 5 ml of rice oil/kg feedstuff, which each treatment included four replicates. It used three female quails for each one male, during 90 days at the age of 16 weeks. The results showed the following: no significant effect (P<0.05) of dietary octacosanol, wheat germ oil and rice oil supplementation which was recorded on relative weights of shell, yolk and albumen, and shell thickness also yolk color, egg shape index, albumen index, yolk index, egg quality of laying quail. However, there was a significant increase (P<0.05) in hough unit for the two treatments that it included octacosanol powder (20 and 25 mg) compared to the control treatment, However, there was no significant difference between the addition treatments.

Abstract Background Transcription is arrested in the late stage oocyte and therefore the maternal transcriptome stored in the oocyte provides nearly all the mRNA required for oocyte maturation, fertilization, and early cleavage of the embryo. The transcriptome of the unfertilized egg, therefore, has potential to provide markers for predictors of egg quality and diagnosing problems with embryo production encountered by fish hatcheries. Although levels of specific transcripts have been shown to associate with measures of egg quality, these differentially expressed genes (DEGs) have not been consistent among studies. The present study compares differences in select transcripts among unfertilized rainbow trout eggs of different quality based on eyeing rate, among 2 year classes of the same line (A1, A2) and a population from a different hatchery (B). The study compared 65 transcripts previously reported to be differentially expressed with egg quality in rainbow trout. Results There were 32 transcripts identified as DEGs among the three groups by regression analysis. Group A1 had the most DEGs, 26; A2 had 15, 14 of which were shared with A1; and B had 12, 7 of which overlapped with A1 or A2. Six transcripts were found in all three groups, dcaf11, impa2, mrpl39_like, senp7, tfip11 and uchl1. Conclusions Our results confirmed maternal transcripts found to be differentially expressed between low- and high-quality eggs in one population of rainbow trout can often be found to overlap with DEGs in other populations. The transcripts differentially expressed with egg quality remain consistent among year classes of the same line. Greater similarity in dysregulated transcripts within year classes of the same line than among lines suggests patterns of transcriptome dysregulation may provide insight into causes of decreased viability within a hatchery population. Although many DEGs were identified, for each of the genes there is considerable variability in transcript abundance among eggs of similar quality and low correlations between transcript abundance and eyeing rate, making it highly improbable to predict the quality of a single batch of eggs based on transcript abundance of just a few genes.

Effect Of Age

The aim was to assess the internal and external quality of consumer eggs of egg‑laying hens of two selected genotypes depending on their age. All of these hens were kept in enriched cages. There were compared eggs from Hy‑Line Brown and ISA Brown hens at the age from 36 to 64 weeks. In total, 3840 eggs from 300 hens were evaluated. Quality of eggs was determined by their technological value. Statistically significant interactions (P = 0.001) between age and genotype were found in all evaluated parameters except for the yolk colour (P = 0.044), whereas there was not found interaction (P = 0.072) between age and genotype in eggshell strength. The significant effect of hens’ age was found in all evaluated parameters, with the only exception of the yolk colour. The results showed that the average weight of eggs, eggshell, albumen and yolk increased with the age. Also the eggshell proportion, its colour and yolk index values ​​increased, whereas the egg shape index, eggshell thickness and strength, albumen proportion, Haugh units, the albumen and the yolk index decreased. Statistically significant effect of the genotype was found in all evaluated parameters except for the yolk index. When comparing both genotypes, the eggs from ISA Brown hens had a better quality. The trend of deteriorating egg quality with age was confirmed.

Supplementation of Averrhoa bilimbi L. juice which contains vitamin C and organic acid in drinking water has been proposed to reduce the effect of heat stress on the quail layer.  So this is expected to increase the productivity of quail and their egg quality. The aim of this research was to determine the effect of A. bilimbi juice supplementation in quail drinking water on quail performance,  physical quality of egg, and egg yolk antioxidant level. Two hundred and forty birds aged 4-5 weeks were maintained for 42 days. A Completely Randomized Design was used in this study with 4 treatments. Each treatment has 4 replications and 15 quails in each replications. Addition of Vita Chick (P0) to the drinking water was used as a positive control. The treatments given were the addition of A. bilimbi extract with different levels of 0% (P1), 2.5% (P2), and  5% (P3) respectively. The variables observed were quail performance, physical egg quality, and egg yolk antioxidant levels. The results showed that the  physical quality of quail eggs obtained were the weight of albumen and egg shells did not different all treatments. The  addition of A. bilimbi juice in drinking water  has affected on the weight and percentage of albumen, eggshell, and Haugh Unit. The addition of 2.5% of A.bilimbi juice (P2)  had the lowest feed conversion ratio (FCR). However it showed the highest Haugh Unit number of the egg. There was no different effect of the highest dose of A. bilimbi juice (5%, P3) on the egg yolk antioxidant  activity and capacity (41.54%  and 23.91 ppm respectively).  It was concluded that supplementation of A. bilimbi juice in drinker water  could  changed to antistress drug commercial.
