Effects of Dietary Turmeric Powder on Laying Performance and Egg Qualities in Laying Hens

Abstract

This experiment was conducted to investigate the dietary effects of turmeric powder (TP) on laying performances, egg qualities and its transfer into eggs. A total of two hundred, 60-wk-old, Lohmann Brown layers were divided into 4 groups, placed in to 5 replicates per group (10 layers each) and fed each one of four diets containing 0% TP (control), 0.10, 0.25 or 0.50% TP, respectively, for 7 wks. Egg production in the all groups fed diets containing TP were significantly higher than that in control (P<0.05). No differences in feed intakes, egg and eggshell qualities were observed among the treatments, but Roche color fan number (yolk color) in group fed diet with 0.5% TP was significantly higher than in control (P<0.05). In the groups fed diets containing TP, Haugh units after 2 wk of storage were significantly higher than that of control (P<0.05). The curcumin content of egg yolk in the groups fed diet containing 0.50% TP was significantly higher than those in the other groups (P<0.05). The cholesterol levels of egg yolk were not influenced by dietary TP. It was concluded that dietary TP was effective in improving laying performance and internal egg qualities. TP can be also used as a feed additive for the production of value-enhanced eggs with increased yolk color and curcumin content.

Turmeric and Vitamin E on the Performance and Quality of Eggs from White Layers

“…According to the authors, turmeric can improve the performance of the digestive tract in laying hens, resulting in improved egg production. [5] showed that turmeric affected egg production, but not egg weight.…”

“…Durrani et al (2006) reported that diet supplemented with turmeric (5 g/kg of diet) resulted in a significant improvement in body weight gain and FCR. Park et al (2012) found that the addition of 0.01, 0.25, and 0.5% turmeric powder in diet of Lohmann Brown laying hens (60 to 67-week-old) significantly increased egg production.…”

Turmeric on Poultry Production: A Review

“…Active ingredients such as tetrahydrocurcuminoids were found in turmeric, according to studies [14]; curcumin, demethoxycurcumin, and bisdemethoxycutcumin have also been found in turmeric [15]. Some studies have been carried out to find out the effects of curcumin on the performance of broilers [16] [17] and laying hens [18] [19]. The antioxidant effect of turmeric has already been reported in the case of broilers [17].…”

“…[25] were able to observe that turmeric powder extract improved the production performance of Ac "Black bone" hens with better egg mass production and feed: egg conversion from 28 to 34 weeks of age and no change in egg mass. [19] showed that turmeric powder affected egg production significantly, but not egg weight. [12] indicated that production and mass of egg increased by addition of turmeric due to the fact that uterus media could have been improved (especially the site of calcium deposit) and result in enhanced shell weight and thickness.…”

“…According to [47], turmeric can be included as an additive in animal feed at a level of 1 and 2% in the total to obtain better and positive results in carcass yield and lean meat production (breast meat), which could reduce the risk of hyperlipidemia and increase consumer acceptability. [19] and [21] reported that serum total cholesterol concentration of layers was not significantly affected by the addition of turmeric, however in a study carried out with turmeric for laying hens, it was reported that cholesterol decreased significantly [48]; the authors reported that turmeric could be useful in the man- [49] reported that turmeric decreased lipid peroxidation due to its antioxidant effects and increased plasma vitamin E in rabbits.…”
