Effects of turmeric (Curcuma longa) powder supplementation in laying hens' diet on production performance, blood biochemical parameters and egg quality traits

Abstract

This study aimed to evaluate the effect of turmeric powder (TP) supplementation on laying hens' performance, blood biochemical parameters and egg quality parameters. In total, 144 laying hens (Hy-line W36) ageing 53 weeks were used in this study. Birds were randomly assigned to three treatments (6 replicates, 8 birds in each). The diets contained 0 (control), 0.25, and 0.5% TP based on the maize−soybean meal. It was found that the TP supplementation significantly reduced egg production, weight and mass throughout the experiment (p < 0.05). However, the feed conversion ratio increased (p < 0.05), whereas feed intake remained unaffected. Yolk percentage, height and index reduced, and the yolk colour, accompanied by the egg-shell percentage, increased (p< 0.05) during the first 4 weeks of the experiment. Interestingly,

Poultry feed fortified with moringa leaves and tumeric leaves to produce functional eggs: a review

“…Turmeric supplementation improved the amount, quality, or content of unsaturated fatty acids in the eggs. According to the study, supplementing a duck's diet with probiotics and turmeric at 2% and 4% can increase both the number and caliber of eggs the ducks lay [9,11] Elkhair et. al [12] examined the effects of supplementing with Moringa oleifera seed powder on heat-stressed Japanese laying quail.…”

“…According to the study, taking turmeric powder at doses of 0.25 percent and 0.5 percent could lower blood triglycerides and increase blood antioxidant activity. Then again, in common natural circumstances, it could lessen laying hen efficiency [11]. Turmeric contains phytoestrogens that can animate egg creation and egg weight in laying hens [12].…”

Effects of Bacillus subtilis Natto NB205 and Its Mutant NBMK308 on Egg Quality in Aging Laying Hens

“…The combination of quercetin and vitamin E improves egg production, egg quality, and immunity in aging breeder hens [ 6 ]. Se-enriched Cardamine violifolia improves laying performance and regulates ovarian antioxidant function in aging hens [ 7 ], while turmeric powder supplementation enhances production performance, blood biochemical parameters, and egg quality characteristics in laying hens [ 8 ]. The potential benefits of melatonin interventions and microbiota involvement in counteracting the effects of oxidative stress on the chicken ovary are demonstrated [ 7 ].…”
