“…All drying methods compared produced significantly different effects (P< .05) with respect to both carotene and xanthophyll concentration. Freeze-drying was the optimum method to maintain the maximum xanthophyll concentration, followed (in decreasing Fletcher et al (1985) reported that xanthophyll levels decreased 18%, from a high of 364 to 299 mg/kg, after only 6 h of field-wilting. Livingston et al (1968) reported xanthophyll losses ranging from 28 to 73% and carotene loss from 0 to 33% during pilot and industrial scale alfalfa processing, with xanthophylls much more susceptible to thermal destruction than carotenes.…”

“…Coastal bermudagrass has been evaluated as a potential xanthophyll source for commercial poultry feed by several authors (Barnett and Morgan, 1959;Wheeler and Turk, 1963;Wilkinson and Barbee, 1968;Burdick and Fletcher, 1984;Fletcher et al, 1985) but apparently no research has been published on feeding common or turf type bermudagrass to poultry.…”

Experiments were conducted to determine the effect of drying method and grass-clipping length on the concentrations of carotene and xanthophyll in turf type bermudagrass (Cynodon dactylon). This lawn grass has potential for use as a xanthophyll source for poultry in the southern US.Oven-drying at 150 C for 40 min, oven-drying at 70 C for 20 h, dark room-drying at approximately 25 C for 120 h, and field-drying in natural sunlight were compared with freeze-drying. The field-drying method resulted in carotene and xanthophyll concentrations of only 15 and 52 mg/kg, whereas freeze-drying yielded the best values: 499 and 886 mg/kg, respectively. Regression analysis of both carotene and xanthophyll content indicated no significant differences that could be attributed to grass-clipping length. (

“…Miller et al (1975) indicated that heating retained more xanthophylls than acid precipitation. Recovery of pigments such as carotenoids and xanthophylls would likely be advantageous in diets for fish and crustaceans for pigmentation (Harpaz et al, 1998;Yanar et al, 2008) and in poultry diets for egg yolk coloration (Fletcher et al, 1985). Additional studies are needed to optimize recovery of these nutrients.…”

Alternative plant‐based protein sources are needed for supplementing or replacing fishmeal in formulated animal feeds. Alfalfa (Medicago sativa L.), a perennial legume, is grown worldwide as a high‐protein forage crop used primarily for dairy and beef cattle feeds. However, its utility as a protein source for feeding other farmed animals has great potential. Wet fractionation can provide several products that increase the value of the crop. The amount of alfalfa protein concentrate (APC) recovered from a fresh press filtrate was measured from several feedstocks: herbage of a nonlodging biomass‐type alfalfa, genetically modified reduced‐lignin alfalfa, and conventional alfalfa as well as from leaves of the biomass type fractionated at harvest. Additionally, five methods for APC recovery were compared. Approximately 854 kg of APC, 7,109 kg of press residue suitable as low quality animal feed, and 4.5 Tg of dry hay could be produced annually from a hectare of biomass‐type alfalfa. The amounts of APC recovered from a reduced‐lignin alfalfa and a conventional cultivar were similar. Acid‐based precipitation methods resulted in the largest recovery of APC, whereas heating produced the highest concentration of protein in the concentrate and highest concentration of methionine, lysine, and threonine. The percentage of fatty acids and sugars in the concentrate varied significantly by precipitation method. All methods resulted in low amounts of fiber in the concentrate. Our results indicate that a nonlodging biomass‐type alfalfa can produce high yields of APC and co‐products with fewer harvests than a conventional cultivar, which reduces costs and promotes crop productivity.

“…Dehydrated grasses such as Coastal bermudagrass and turf bermudagrass also represent potential xanthophyll sources for commercial poultry feeds. The utilization of Coastal bermudagrass as a pigmenting agent to laying hens has been well documented (Barnett and Morgan, 1959;Wheeler and Turk, 1963;Wilkinson and Barbee, 1968;Marusich and Bauernfeind, 1970;Burdick and Fletcher, 1984;Fletcher et al, 1985). .Turf bermudagrass has also recently been evaluated as a pigmenting source for laying hens (Chen Authors and Bailey, 1988;Bailey and Chen, 1988a).…”

The characterization of xanthophylls in egg yolks from laying hens fed turf bermudagrass (Cynodon dactylon) meal was studied. Laying hens were fed 2 wk on a mile-soybean meal diet to deplete the birds' xanthophyll stores from developing ova prior to introduction of 9% turf bermudagrass. After an additional 4 wk the various carotcnoids present in egg yolks were determined by open-column, thin-layer, and high-performance liquid chromatography. Chromatographic analyses suggest that the yolk color was due mainly to the prcsencc of free lutein and zeaxanthin at a ratio of 4:l. Neoxanthin and violaxanthin wcrc present in minor amounts. The presence of p-carotene was not detected.
