    Effects of dietary licorice root (Glycyrrhriza glabra) supplementation, storage time and temperature on quality of quail eggs
    (Mattioli 1885, 2018) Doğan S.C.; Baylan M.; Yaman S.; Bulancak A.
    This study was conducted to investigate the effect of licorice root (Glycyrrhriza glabra) supplementation, different storage temperature and storage time on egg quality in quails. Two hundred and forty 10-wk-old laying Japanese quails, randomly divided into four equal groups for dietary treatments, were fed using the commercial diet as a control group and the commercial diet supplemented with 0.5, 1.0 and 1.5% licorice root powder. The forty eggs were sampled and weighed for each one of storage time groups (i.e. 15, 30 and 45 days), and were stored at +4°C and +25°C. Egg internal and external quality characteristics were determined at the end of each storage period for each temperature. The egg albumen pH level was increased in a parallel of the escalation of storage time and temperature, whereas it was decreased as the licorice level was increased. Haugh Unit (HU) value was decreased with an increase of storage time and temperature, but it was increased in a parallel of accelerating level of licorice root. Though there were no significant differences in egg weight loss, yolk index and egg shell weight between the treatments, they were significant for the albumen index and egg shell thickness (P<0.05). Moreover, albumen index and egg shell thickness were increased with an enlarged licorice root supplementation. It was concluded that the use of licorice root in laying quail diet may be effective for the expansion of egg shelf life. © Mattioli 1885.

    The effects of licorice (Glycyrrhriza glabra) root on performance, some serum parameters and antioxidant capacity of laying hens
    (Fundacao APINCO de Ciencia e Tecnologia Avicolas, 2018) Canogullari Dogan S.; Baylan M.; Erdoğan Z.; Küçükgül A.; Bulancak A.
    The current study was conducted to determine the effects of the licorice root (Glycyrrhriza glabra) in laying hens diets on performance, egg cholesterol, some plasma parameters and antioxidant capacity. One hundred, 40-week old laying hens were divided into four groups, each group consisted of 25 hens and were placed in individual cages. The mean of the initial body weight of laying hens was 1829.18±9.595 g. Commercial laying hen diet was supplemented with 0, 0.5, 1.0 and 2.0% levels of licorice root powder and four different dietary groups were formed. From the experimental findings, it was ascertained that the licorice root supplementation had no significant effect on egg weight and feed conversion ratio (p>0.05), but feed consumption decreased with increasing licorice root (p<0.05).Egg yield was recorded as 88.94%, 89.56%, 86.82% and 85.02% in the groups of 0, 0.5, 1.0 and 2.0, respectively (p<0.05).Plasma low density lipoprotein (LDL) and egg yolk cholesterol level decreased with the addition of licorice root, while plasma high density lipoprotein (HDL) level was increased with licorice root addition (p<0.05). Licorice root addition had a positive effect on total antioxidant capacity (TAS) of plasma. It was determined that the total antioxidant capacity was increased by increasing amount of licorice root. From the overall findings, it can be concluded that licorice root could be used as a feed additive without any adverse effect on performance. It has been demonstrated that the licorice root enables the production of functional eggs. © 2018, Fundacao APINCO de Ciencia e Tecnologia Avicolas. All rights reserved.
