“…(2008) where feeding flaxseed oil did not change the total fat content but did manipulate the FA profile of the yolk itself. Feeding increased concentration of flax oil as free oil or milled flaxseed linearly increased deposition of EPA and DHA in the yolk ( Ehr et al., 2017 ). Cherian and Sim (1991) reported that egg yolk fat content is limited to 10% of the total yolk—this plateau is influenced by the total ALA, EPA, and DHA composition in the diet.…”

“…Incorporation of flaxseed in practical poultry diets often results in variable responses and is dependent upon a multitude of factors such as processing, enzymes, and cultivation time. For example, laying hens deposited twice the amount of n-PUFA in the yolk when fed a diet containing free flaxseed oil compared with hens fed milled flaxseed to supply similar level of dietary oil concentration ( Ehr et al., 2017 ). Flaxseed fed in mash vs. crumble resulted in significantly different nitrogen-corrected apparent metabolizable energy ( AMEn ) in broilers, roosters, and laying hens ( Leeson and Summers, 2000 ).…”

The effects of coextruded full-fat flaxseed and pulses ( FFF ; 1:1 wt/wt) mixture on n-3 polyunsaturated fatty acids ( PUFA ) enrichment in egg yolk, hepatic attributes, apparent retention ( AR ) of components, and ceca metabolites were evaluated in broiler breeder hens. The diets were as follows: 1) corn–soybean control, 2) control diet plus 18% FFF ( FFF− ), and 3) FFF plus enzyme supplement ( FFF+ ) containing galactanase, protease, mannanase, glucanase, xylanase, amylase, and cellulase activities. Twenty-six-week-old Cobb 500 broiler breeder hens were allocated to 30 identical cages (2 hens/cage) and given 1-week adaptation period. The 3 diets were assigned to 10 replicate cages based on postadaptation BW and fed based on breeder curve for 30 D. Excreta samples were collected from day 24 to 27 for determination of AR of components, and eggs were collected from day 28 to 30 for yolk polyunsaturated fatty acids analyses. On day 30, birds were weighed, killed via cervical dislocation, liver weighed, and stored for fat analyses. Ceca digesta samples were taken for concentration of short-chain fatty acids. Liver and yolk weights as well as total yolk FA were not influenced by diets ( P > 0.05). Control birds had lower yolk concentration of α-linolenic acid than birds fed either FFF− or FFF+ ( P < 0.01) corresponding to 7.5, 36.8, and 37.3 mg/g for the control, FFF−, and FFF+, respectively. Control birds also exhibited lower yolk concentration of docosahexaenoic acid ( P < 0.01). Control birds had higher hepatic concentration of crude fat and apparent retention of dry matter and crude protein compared with either the FFF− or FFF+ birds ( P < 0.05). Birds fed FFF- diet had lower ceca digesta concentration of lactic acid than control and FFF+ ( P < 0.05) birds. Results showed broiler breeder hens enriched egg yolk with n-3 polyunsaturated fatty acids without effects on the liver while the supplemental enzyme did not improve the utilization of FFF.

“…The yolks of eggs from hens that were fed flaxseed oil or ground flaxseed have also been shown to be enriched in omega-3 fatty acids. (Ehr et al, 2017). Enriching eggs with omega-3 PUFA may enhance their antioxidant status and reduce lipid peroxidation, which may improve the immune response in laying hens.…”

This study aimed to evaluate effects of supplementing the diets of laying hens with different sources of Se and different levels of flaxseed on egg Se concentration, yolk antioxidant properties and immune response. In a completely randomized design, 384 Hy-Line W-36 hens (aged 50 weeks) were assigned to a 3 × 4 factorial arrangement, comprising four replicates of eight hens. For 10 weeks, the birds were fed one of three basal diets containing 0, 50, and 100 g/kg of flaxseed and regular Se content from mineral premix, supplemented with no additional Se (SN) and 1 mg/kg of Se from sodium selenite (SS), Se-enriched yeast (SY), and hydroxy selenomethionine (SOH). The greatest Se concentration in the yolk was observed in diets containing organic Se sources. The SOH diet produced the greatest albumen Se concentration, followed by SY, and then SS. Using any Se supplementation improved glutathione peroxidase activity and total antioxidant capacity, compared with SN. However, superoxide dismutase activity and malondialdehyde were not affected by Se supplementation. Cell-mediated immune response was improved by Se supplementation, especially SS. Antibody response against sheep red blood cell (SRBC) was not affected by Se source, except that IgM was greater in the hens that received SS and SY. Neither flaxseed supplementation, nor its interaction with Se source was significant for any trait. Thus, supplementation of diets with 1 mg/kg Se, especially from organic sources, enriched the egg and improved some yolk antioxidant properties and immune system function. Supplemental flaxseed did not influence any measured traits.

“…Furthermore, recent studies showed that herbal enriched super eggs can be obtained from laying hens fed with diets supplemented with phytobiotics, herbs containing secondary metabolites such as garlic, onion, basil leaves, turmeric powder, citrus pulp, flaxseed (Damaziak et al, 2017;Mirbod et al, 2017;Ehr et al, 2017). It is therefore envisaged that performance and egg qualities will be improved in laying hens fed diets containing ginger, turmeric and garlic especially at older age.…”

Performance and egg qualities of old-laying hens fed with diets containing ginger, turmeric and garlic were evaluated in a twelve (12) week feeding trial. A total of 135 laying birds of Isa-Brown strain which were sixty-four (64) weeks old were used for the trial and arranged in a completely randomized design. Five diets were formulated for the trial: Diet 1 (control), Diet 2 (3% inclusion level of turmeric), Diet 3 (3% inclusion level of ginger), Diet 4 (turmeric and garlic at 2.25% and 0.75%, respectively) and Diet 5 (ginger and garlic at 2.25% and 0.75%, respectively). Proximate compositions of the Phytogenic Feed Additives (PFAs) were determined with the moisture content ranging between 5.03-7.50%; ash (3.26-6.11%); ether extract (7.39-14.58%); fibre (10.28-13.79%); protein (3.07-7.23%) and Nitrogen Free Extract (58.88-61.54%). The performance indices, though not significantly (P˃0.05) influenced by the test diets except for Hen Day Production (HDP) had the highest weight gained (0.16kg) recorded for birds fed on a diet containing ginger. The highest (62.92 and 62.04 %) HDP were observed in birds fed diets containing ginger and ginger + garlic; respectively. However, the lowest weight gained (0.04kg) was recorded in birds fed a diet containing turmeric + garlic; this diet also recorded the lowest % HDP and FCR with values of 57.50% and 2.37 respectively. The overall values for the qualities of eggs from laying hens fed the PFAs showed that only the Haugh Unit, yolk colour and albumen height were significantly (P˂0.05) affected; with those on Turmeric + Garlic diets having the highest for these parameters. However, the fatty acid variables were not significantly (P˃0.05) affected by the dietary treatments. It could be concluded that the inclusion of PFAs in the diets of laying hens especially at an older age would help to sustain performance with improved quality.
