Turmeric and sorghum for egg-laying quails

Abstract

The aim of the present study was to assess the effect of adding different turmeric amounts to sorghum-based diets for Japanese quails on animal performance, animal metabolism, yolk colour, egg quality, blood and liver biochemical parameters and sensory attributes of the eggs. The study included 210 egg-laying quails aged 50 days and lasted for 90 days. The study had a completely randomised design with six treatments and five replicates with seven birds per replicate. A control corn-based feed and sorghum-based feeds to which different turmeric levels were added (0%, 0.5%, 1.0%, 1.5% and 2%) were tested. The results showed that the sorghum-based feeds with added turmeric levels did not affect animal performance, metabolisation of protein and ether extract, internal and external quality of eggs, serum biochemical profile, including calcium, phosphorous, protein and liver transaminase enzymes. Blood cholesterol and triglyceride levels decreased when !0.5% percentages of turmeric were added to the feed. Yolk colour of the treatments differed significantly from that of the control, but the yolks were considered well suited for consumption. Turmeric reduced the cholesterol and triglyceride levels in egg-laying quails.

Black Soldier Fly (Hermetia Illucens) as Dietary Source for Laying Quails: Live Performance, and Egg Physico-Chemical Quality, Sensory Profile and Storage Stability

“…Independently to the dietary treatment, the weight of the eggs produced by quails in the present experiment was higher (14.5 g) than values commonly found in literature [18]. Birds of the present study were almost at the end of their productive career, whereas most research studies considered 8–12 weeks-old birds [33].…”

“…The pH values recorded during the storage trial on quails’ eggs were slightly lower than values presented by Silva et al [18]. This finding was not surprising as albumen pH gives a clear indication of the freshness of the egg and, in the present experiment, pH measurement was conducted the day after the eggs were laid.…”

“…Despite this, the influence of BSF larvae meal in laying quails’ diets is not clear yet. Quail production has been increasing in the last years, thanks to a series of positive intrinsic characteristics of this avian species: It provides high quality meat and eggs with fast return on investment, thanks to the early sexual maturity, rapid growth, short generation interval, high laying rate and limited feed and space requirements per bird [17,18].…”

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

“…[1] observed a greater presence of white color in the egg yolks when they replaced 50% of the corn from the layer diet by sorghum and used 2% of dry turmeric rhizome. Also [14] concluded that dry turmeric rhizome was not a good pigment for quail egg yolk staining.…”

Productive performance, egg-related indices, blood profiles, and interferon-Ɣ gene expression of laying Japanese quails fed on Tenebrio molitor larva meal as a replacement for fish meal

“…Eggs are low-cost source of high-quality protein, lipids, vitamins and minerals (Miranda et al 2015) with rapidly increasing production, expected to reach the 89 million ton by 2030 (Secci et al 2018). In this respect, quail egg production has been increasing in recent years due to early sexual maturity, short generation interval, high laying rate and limited feed and space requirements per bird (Gonz alez 1995;Silva et al 2018). On the other hand, the higher need to poultry production increases the need to further feed, accounting for more than 65% of variable expenses of producing poultry products (Kiarie et al 2013).…”
