Backyard poultry production forms the basis for transforming the rural poultry sector from subsistence to a more economically productive base. The current study was conducted to evaluate the egg quality of eggs produced by Athulya, native and IWN x Native crossbred layers under backyard system. At 36 weeks of age, one egg from each group of birds was collected for fatty acid estimation of egg yolk and 20 eggs from each group was collected at 40 weeks of age for assessing the haugh unit score, yolk colour, shell thickness and shell colour. The beneficial polyunsaturated fatty acid content was higher in native bird eggs. The eggs from Athulya and native chicken had better internal quality in terms of haugh unit and yolk colour score. The shell thickness of eggs was similar among three groups. The egg shell colour was white in Athulya, tinted to brown in native and tinted in IWN x Native crossbreds and the shell colour in native and crossbreds exhibits more consumer preference.

Consumer interest in buying eggs from animal welfare-friendly systems with outdoor access is increasing, leading to an increase in the need for knowledge on genotypes suitable for free-range systems. Two Turkish laying hen genotypes, Atak-S (brown, n = 210) and Atabey (white, n = 210), were reared in a free-range system from 19–72 weeks of age, and their suitability for the system was assessed based on laying performance, egg quality, and yolk fatty acid profile. Mean hen-day and hen-housed egg production were found to be higher in Atabey than Atak-S (p < 0.01). The brown eggs from Atak-S hens tended to be heavier than the white eggs from Atabey hens (p < 0.01). Brown eggs obtained from Atak-S hens had a stronger shell structure (p < 0.01), while white eggs from Atabey hens had higher mean yolk index, albumen index, and Haugh unit than brown eggs (p < 0.05). At 56 weeks of age, total saturated fatty acid content in yolk was higher in white eggs than in brown eggs (p < 0.01). These findings related to genotype could help free-range egg producers in their choices for more profitable production and for meeting consumer demands on egg quality and egg yolk fatty acid levels.

ABSTRACT The bromelain enzyme content in pineapple peel waste predicted to promote digestive tract health and a positive effect on egg quality. This research aimed to evaluate the use of fermented pineapple peel waste in laying hens diet on egg quality. A total of laying hens 200 birds with Isa Brown strain, egg production of 70%, The average egg weight and body weight were 58.58 g/egg, and 1.62 g/bird, respectively. A completely randomized design was used, 5 different levels of fermented pineapple peel waste as treatment (0, 5, 10, 15, and 20%), and all treatments were repeated 4 times. Egg shell thickness, egg shell strength, haugh unit, egg yolk fat, and egg yolk color were measured. The use of fermented pineapple peel waste in the diet of laying hens up to 20% highly significant (P<0.01) on egg yolk color, and did not negative effect (P>0.05) on egg shell thickness, egg shell strength, haugh unit, and egg yolk fat. Fermented pineapple peel waste can be used as much as 20% in laying hens diet without disturbing egg quality and improve egg yolk color.

In order to investigate the effects of omega (n) 3 fatty acids on egg quality a group-control trial was organized. Trial lasted 40 days and was performed in production conditions. Total number of 1264 laying hens of Lohman Brown classic provenience were used and randomly allotted into one of four groups by 316 hens each (C-control, I experimental, II experimental and III experimental). All groups of hens were fed diets of standard ingredients and chemical composition, while feed of I, II and III experimental group of hens was supplemented with micro algae Schizochytrium spp. (DHA Gold?, Martek, USA) as a source of n- 3 fatty acids in amount of 0.5, 0.7 and 1.0 % respectively. In order to investigate the influence of micro algae Schizochytrium spp. feed supplementation on egg quality, from the aspect of content and ratio of fatty acids, random egg samples (n=10) were taken at the 10th, 20th and 40th day of the trial from each group. Egg yolk fatty acid content was determined by gas chromatography on Varian 1400 with flame ionization detector (FID detector) (on a packed column 20% LAC-3R-728 Chromosorb WAW 80-100 mesh). Significant differences in egg yolk fatty acid content as well as their ratio were determined between treatment groups. Positive influence of supplemented micro algae preparation was observed. Highest content of n-3 poly unsaturated fatty acids (PUFA n-3) was determined in egg yolks of III experimental group while lowest content was determined in egg yolks of control group of hens. Micro algae feed supplementation, at the end of the trial period, positively affected egg yolk PUFA n-6/PUFA n-3 ratio, since determined ratio of 4.24 in III experimental group was more desirable than 12.27 determined in a control group. Marine algae (Schizochytrium spp.) feed supplementation in laying hens in amounts above 0.5% significantly affected egg yolk fatty acid composition as well as ratio of n-6/n-3 PUFA. These findings support its use from nutritive, medical and economic point of view.

In this study, the performance, egg quality, egg yolk colour and fatty acids profile of quails fed on diets containing different fat sources were determined. During 8 weeks trial, a total of 75, 10-weeks-old laying quails were used. Three diets were formulated to contain soybean oil (SBO), sunflower oil (SFO) and hempseed oil (HSO), respectively. The performance parameters were not significantly influenced by the dietary different oil sources. Eggshell ratio, eggshell thickness, eggshell breaking strength, egg shape index, egg yolk index, albumen index and egg yolk colour values (except a*) were not influenced by the different dietary oil sources. The a* value was significantly affected and the highest a* value was the HSO of group. The different oil sources supplementation to the diets was effective on fatty acid composition of the egg yolk. The highest value in terms of α-linolenic acid, total polyunsaturated fatty acids and total n-3 fatty acids were found in the diet fed group with HSO added. As a result; supplementation of different sources of oil to quail diets without negatively affecting performance and egg quality can be used to change the egg yolk fatty acid composition. Hempseed oil may increase the amount of total polyunsaturated fatty acids and total n-3 fatty acid content of egg yolk.

Salinity is a known factor in shaping population dynamics and community structure through direct and indirect effects on aquatic ecosystems. Salinity changes further influence food webs through competition and predation. The responses of Moina macrocopa (Cladocera) collected from Setiu Wetland lagoon (Terengganu) was evaluated through manipulative laboratory experiments to understand the ability of M. macrocopa to tolerate high salinity stress. Specifically, the fatty acid composition, growth, survival, and reproduction of this cladocerans species was examined. Sodium chloride (NaCl) as used in the treatments water with the concentration 0, 4, 6, 8, 12, and 15 salinity. Fatty acid levels were determined using Gas Chromatography and Mass Spectrophotometry (GC-MS). The results indicated that optimal conditions produced the highest fatty acid content, especially the polyunsaturated fatty acid content, such as EPA (eicosapentaenoic acid), ALA (alpha-linoleic acid), ARA (arachidonic acid), and DHA (docosahexaenoic acid). Furthermore, M. macrocopa survival was best at salinity 0, with a percentage of 98%, whereas the opposite occurred at salinity 15, with approximately 20% of viable animals surviving. Besides, M. macrocopa also showed the highest reproduction rate at salinity 0 (e.g., average initial age of reproduction, 4.33 ± 0.58 days) compared with other salinities level. Interestingly, the difference in growth at different salinities was not evident, an unusual finding when considering adverse effects such as osmoregulation pressure on the organism. Based on the results, we conclude that M. macrocopa can only tolerate salinity below salinity 8 and cannot withstand stressful environmental conditions associated with salinities above 8.

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.
