“…Further, shell thickness influences the egg shell weight, which is the cause of significant shell weight differences (p<0.05) recorded between the groups in the present study. In birds, L-AA augments conversion of 1,25 dihydoxycholecalciferol in the kidney and increases calcium mobilization from skeleton which suggests its role in egg shell formation and strength (Dorr and Balloun, 1976; Bollengier-Lee et al, 1999). Besides, the content of organic matrix in the shell is positively correlated to the available ascorbic acid.…”

Environmental stress boosts the levels of stress hormones and accelerates energy expenditure which subsequently imbalance the body’s homeostasis. L-ascorbic acid (L-AA) has been recognized to mitigate the negative impact of environmental stress on production performances in birds. The present investigation was carried out to elucidate the effect of different dietary levels of L-AA on production performance, egg quality traits and fertility in Japanese quail at low ambient temperature. Sixty matured females (15 wks) were equally divided into three groups (20/group) based on the different dietary levels of L-AA (0, 250 and 500 ppm) and coupled with an equal number of males (1:1) obtained from the same hatch. They were managed in uniform husbandry conditions without restriction of feed and water at 14 h photo-schedule. Except for feed efficiency, body weight change, feed consumption and hen-day egg production were recorded highest in 500 ppm L-AA supplemented groups. Among the all egg quality traits studied, only specific gravity, shell weight and thickness differed significantly (p<0.05) in the present study. Fertility was improved significantly (p<0.01) to a dose dependent manner of L-AA. The findings of the present study concluded that dietary L-AA can be a caring management practice at least in part to alleviate the adverse effect of cold induced stress on production performance in Japanese quail.

“…It has been reported that ascorbic acid plays arole in bone maturation by improving hydroxyproline production which is required for collagen formation. Accordingly, in birds it was postulated that ascorbic acid stimulates 1, 25dihydroxy cholecalciferol and together with it in increases calcium mobilization from bones, suggesting vitamin C has an important role in egg shell formation (Dorr and Balloun, 1976).…”

The effect of chromium (Cr) and ascorbic acid (AA) as a dietary supplementation on digestion of nutrients, mineral concentration, egg quality and hematological parameters in laying hens were studied under winter condition (December-February). Total number of 275 (250 hens + 25 cocks) Dokki4 chickens, of 30 weeks old were divided into 5 groups of 5 replicates each (10 hens +1 cock/ replicate). Birds in the 1st group (Cont.+) were kept in controlled normal temperature (CNT,25C) with 64±2% relative humidity (RH) and fed corn-soybean meal basal diet (16.4% crude protein, 2750 kcal ME/kg diet), without any supplementation. Birds in groups from 2 to 5 were exposed to natural low temperature (NLT, 8-18C) with 65±2%. These groups were fed either basal diet (Cont.-), or the basal diet supplemented either with either 250 ppm AA, 400 ppb Cr or 250 ppm AA plus 400 ppb Cr. Results obtained showed that except for crude fiber, cold stress impaired nutrient digestibility and mineral retention compared with those of birds exposed to normal ambient temperature. A combination of AA and Cr rather than each alone, provided the better digestibility of dry matter, crude protein, ether extract and mineral retention. The highest values of nutrient digestibility and Ca, P, Fe and Zn retention were observed with the combination of AA + Cr group while the lowest values were showed with the control group. It could be concluded that the combination between AA + Cr may improve the retention of nitrogen and mineral retention in laying hens under low ambient temperature. Low temperature decreased yolk weight, shell weight, yolk index, shell thickness and Haugh unit. The results showed that there was no significant (p≤0.05) effect of treatments on blood hemoglobin. The results showed that low temperature decreased total lymphocytes cells while, erthrocytes, leukocytes, heterophil and H/L ratio were increased by cold weather compared to control birds at normal temperature. Lymphocytes cells are significantly higher (p≤0.05) in the group fed the combination of AA and Cr than groups fed AA or Cr alone. However, erthrocytes, leukocytes and heterophil were lower in the groups supplemented with AA and /or Cr than the low temperature control birds (p≤0.05). The results of the present study conclude that a combination of 250 mg of AA and 400 mg of Cr provides the highest positive effect on nutrients digestion, mineral concentration, egg quality and hematological parameters of local laying hens under winter condition in Egypt .

“…Sahin and Onderci (2002) detailed that a diet blend of vitamin C at level 250 mg/kg and Cr at level 400 μg gives the most raised useful results on the exhibition and egg quality attributes of laying birds under a low temperature. Dorr and Balloun (1976) reported that in birds, it had proposed that vitamin C corrosive animates 1, 25-dihydroxycholecalciferol and alongside it increments calcium arranging from bones, recommending that vitamin C has a colossal effect in eggshell course of action. The aim of this research is to study the effect of using chromium chloride or L-carnitine either alone or with vitamin C during heat stress in the summer on egg production and egg quality of Golden Montazah hens.…”

Two experiments were done in this experiment to evaluate the comparison of the use of chromium chloride (Cr) as CrCl3 and L-carnitine, either alone or in combination with vitamin C, during heat stress in the summer on the egg performance and egg quality. In each experiment, one hundred and twenty individual of a 28-week golden Montazah-layer hen, according to a completely randomized design were divided into four groups, each group had three replicates, and each replicate had 10 laying hens. Layers were housed in cages (one bird/cage) and at high ambient temperatures (day and night cyclic temperatures ranged from 28 to 42°C) throughout the 12-week trial period. Layers have been fed by commercial classes throughout the experiment with access to feed and water. In1st experiment, the treatments were Group 1 = control, (0 additives), group 2 = vitamin C, (250 mg/kg feed), group 3 = Cr, (400 mg/kg feed), group 4 = (Cr 400 mg/kg feed + vitamin C 250 mg/kg feed). In 2nd experiment were Group 1 = control, (0 additives), group 2 = vitamin C, (250 mg/kg feed),, group 3 = L-carnitine, (100 mg feed), group 4 = (L-carnitine 100 mg feed + vitamin C 250 mg/kg feed), The results indicated that groups supplementation of 400 mg (Cr) and 100 mg L-carnitine either alone or combination with 250 mg vitamin C /kg diet improving feed conversation, egg number, egg mass and egg production percentage compared with control group or vitamin C alone, while egg weight increased by using L-carnitine with vitamin C compared with other groups. Also results demonstrated feeding supplemental (Cr) and L-carnitine, either alone or in combination with vitamin C had no effect on egg length, egg diameter, egg shell thickness, egg shell weight but its increased albumen height (p<0.01). It can be concluded that supplementation of 400 mg (Cr/kg feed) and 100 mg L-carnitine /kg feed either alone or combination with vitamin C 250 mg /kg diet, improved production performance for Golden Montazah hens at 29-40 weeks of age during the summer season.
