“…Assuming equal carotenoid intake among age classes, the first possibility can thus be discarded. In contrast, intestinal absorption efficiency and blood transport may be influenced by the absorption and circulation of lipids, particularly cholesterol (Surai 2002;McGraw and Parker 2006), and evidence from poultry indicates that cholesterol levels increase with age (Dikmen and Sahan 2007). Oxidative stress in blood could also reduce the availability of carotenoids for pigmentation .…”

Many animal species show ornaments with yellow-orange-red colors produced by carotenoid pigments. Such traits have evolved as reliable signals of individual quality because of the costs inherent to their production or maintenance. In animal tissues, carotenoids are often found combined with free fatty acids, as carotenoid esters, which may confer more stability to coloration than free carotenoids. Surprisingly, the potential relevance of carotenoid esterification in the expression of animal sexual signals has been virtually ignored. Moreover, the sources of variability of esterified carotenoid levels are barely known, because most studies have not quantified their concentrations. Here, carotenoids in the ornaments (bill, eye rings, and legs) of red-legged partridges Alectoris rufa were quantified in their free and esterified forms. Carotenoid ester levels were the best predictors of leg color, whereas the redness of the other traits was better explained by free carotenoids. Nonetheless, total carotenoid levels (the sum of free and esterified forms) were always significantly correlated to redness. Young partridges had lower levels of free and esterified carotenids in the legs than did older individuals. Also, wild animals had higher ester levels and a higher proportion of carotenoids in esterified forms in all traits than did captive partridges. Probable physiological mechanisms explaining these patterns are discussed.

“…However, to reduce cholesterol contents is not easy without reducing egg production and weight. Dikman and Saham (2007). According to recommendation by Leeson and Summers (2005), the laying hens aged 18 -32 weeks old need 20 g crude protein/hen/day and 260 Kcal ME/hen/day.…”

The design used in this study was a The objectives of this study were to analyze the eggs’ nutritional characteristics and quality from laying hens fed with dried papaya (Carica papaya L) peel meal diets. A total of 200 brown laying hens strain MB 402 (42 week-old) were used in this experiment. The design used in this study was a completely randomized design (CRD) consisting of 5 treatments and 4 replications (10 hens each). The treatments consisted of dried papaya peel meal (DPPM) 0%, 3%, 6%, 9% and 12%. Total feeding trial was 8 weeks. The parameters recorded included egg weight (g/bird)), egg yolk weight (g/bird), yolk index (%), albumen index (%), egg yolk color, egg cholesterol (mg/100g), egg crude protein (%), egg crude fat (%), egg white crude protein (%), egg yellow fat (%), eggshell calcium (%), eggshell phosphorus (%), blood cholesterol (mg/dl), blood LDL cholesterol (mg/dl), and blood HDL cholesterol (mg/dl) of the laying hens. The results showed that feeding birds with 12 % increased egg yolk weight, egg yolk color, egg crude fat, egg yellow fat, egg cholesterol, egg shell calcium, egg shell phosphor, blood cholesterol, blood HDL. Moreover there were no significant differences in egg weight, yolk index , albumen index, egg crude protein, egg white crude protein and blood LDL. In Conclusion, DPPM diets can be fed to the laying hens up to 12 % to produce eggs without negative effects on the egg quality.ransomized design (CRD) consisting of 5 treatments and 4 replications (10 hens each).

“…This is mostly due to the significant effect of both maternal and paternal components (parents) on fertility and early embryo survival. Literature showed that hatchability reduction of eggs from older broiler breeders is a result of many contributing factors, including larger egg size (Leeson & Summers 2000), increased early and late embryo mortality (Elibol & Braket 2003), poorer shell quality due to bigger surface area (Bennett 1992), albumen quality deterioration (Tona et al 2004) and increased the yolk cholesterol content (Dikmen & Sahan 2007). Ransin (2005) provided the fertility and hatchability goals at certain ages of breeder flock.…”

A total of 2000 Hubbard Classic females and 180 males (male to female ratio 1:11) close to standard body weights were selected and managed separately in the same shed. The objective of this experiment was to study the effects of egg size (small, medium and large) at mid (45 weeks) production cycle and flock age (30, 45 and 60 weeks old) on hatching egg weight loss, fertility, hatchability traits, chick weight and chick yield in a commercial Hubbard Classic broiler breeder flock. The results showed that minimum egg weight loss (P ≤ 0.05) was recorded in large egg size group at different incubation periods and egg weight losses decreased with advancing the age of breeder hens. Maximum fertility and hatchability (P ≤ 0.05) was noticed in small egg size group, followed by medium and large egg size groups. However, maximum embryonic mortality (P ≤ 0.05) during incubation and higher percentage of infertile eggs was recorded in large size egg group, followed by medium and small egg size groups. Low fertility, hatchability was recorded (P ≤ 0.05) in older hen at the age of 60 weeks. The chick weight and chick length were amplified (P ≤ 0.05) with increasing the egg size. However, egg size was not influenced (P ≥ 0.05) on chick yield. The chick weight, chick yield and chick length were improved (P ≤ 0.05) with advancing age of broiler breeder.
