Effect of Pomegranate Molasses on Egg Quality Traits During Different Storage Time in Laying Hens

Abstract

The present study trial was conducted to investigate the effects of pomegranate molasses on egg quality at different storage periods. A total of 240 Babcock white laying hens (58 weeks old) were divided into 5 groups (n=48) with 8 subgroups having 6 hens in each. Pomegranate molasses was added in the drinking water to experimental groups with 0%, 0.1%, 0.25 %, 0.5%, and 1%, respectively during 4 weeks. At the end of study (30 days), total of 320 eggs were collected randomly and eighty eggs (80) were analyzed at 0 day of storage while other eggs were stored at 4°C temperature for 10, 20 and 30 days. The result reveals that the egg weight, egg shell thickness and albumin index remained non-significant (P>0.05) during the whole trial Moreover , Haught unit showed positive response in the group B and D at 10 day storage as compared with control group however, it was remained non-significant (P<0.05) at 0, 20 and 30 days of storage. It is concluded that pomgranate mollases has shown positive effect on some egg quality traits during several storage periods 0, 10, 20, 30 days.

“…However, Gültepe et al [17] reported a positive effect of lemon juice on the performance of older laying hens. Additionally, Çetingül et al [18] reported that providing pomegranate molasses in drinking water to laying hens had no major effect on egg quality after 30 days storage at 4°C, although it had some minor effects in earlier storage days. In our knowledge, this is the first report on the effects of water supplementation of MPE on the performance of laying hens.…”

“…Gültepe et al [17] observed some positive effects of lemon juice as a water supplement on egg production during the late phase production cycle of laying hens. Furthermore, Çetingül et al [18] reported that supplementation of pomegranate molasses with drinking water to laying hens may affect some quality parameters in eggs after 30 days of storage.…”

Potential Implications of Natural Antioxidants of Plant Origin on Oxidative Stability of Chicken Albumen during Storage: A Review

“…Natural plant products, such as natural astaxanthin [32], pumpkin seed meal at 9% [30], Chinese herbal extracts [93], marigold extract [49], and tea polyphenols [29], maintained HU values during storage compared to controls. In another study, pomegranate molasses enhanced HU values compared to controls, but not beyond ten days during 30 days of storage [55]. In addition, dietary peptides [98] and natural vitamin E antioxidants [99] slowed the rate of HU decline in stored eggs and preserved their shelf life.…”

“…Reduced HU values during storage indicate a loss in albumen quality, and when HU values of stored eggs are similar to those of fresh eggs, this suggests that albumen quality is preserved, with extended shelf life. Previous studies [33,54,55,96] have demonstrated that supplementation with natural plant antioxidants in the diets of laying hens reduced the rate of decline in the HU values of stored eggs and preserved the shelf life of albumen. Natural plant products, such as natural astaxanthin [32], pumpkin seed meal at 9% [30], Chinese herbal extracts [93], marigold extract [49], and tea polyphenols [29], maintained HU values during storage compared to controls.…”
