Abstract The advantage of supplemental sodium bicarbonate (NaHCO3) on eggshell quality in laying hens changes with age. Besides increasing calcium (Ca) secretion in the eggshell gland, it may improve Ca absorption in the intestine or kidney. Hy-Line Brown layers (n = 384), 25 weeks of age, were allocated to two treatment groups in two experiments, each of which included 4 replicates of 24 hens. Hens were fed a basal diet (control) or the basal diet containing 3 g NaHCO3 g/kg for 50 or 20 weeks… Expand
Dietary supplementation with sodium bicarbonate or sodium sulfate affects eggshell quality by altering ultrastructure and components in laying hens.
Dietary supplementation of NaHCO3 or Na2SO4 could increase eggshell breaking strength, which may be related to increased sulfated GAG contents in eggshell membranes and improved ultrastructure. Expand
Effects of dietary supplementation of arginine-silicate-inositol complex on absorption and metabolism of calcium of laying hens
The effects of supplementation of arginine-silicate-inositol complex (ASI; 49.5–8.2–25 g/kg, respectively) to laying hens were investigated with respect to eggshell quality, calcium (Ca) balance, andExpand
The partial replacement of sodium chloride with sodium bicarbonate or sodium sulfate in laying hen diets improved laying performance, and eggshell quality and ultrastructure
Overall, dietary Cl reductions could improve laying performance and eggshell quality by substitution of NaHCO3 or Na2SO4 for part of NaCl, and there were no differences in the improvements between these two substitutes. Expand
Effects of Dietary Phosphorus Level on the Expression of Calcium and Phosphorus Transporters in Laying Hens
Both the phosphorus absorption in proximal intestine and its reabsorption in kidney are involved in the adaption to low AP diet, and both the Ca and P transporters were highly expressed in duodenum. Expand
Effect of Pre-Slaughter Antacid Supplementation of Drinking Water on Carcass Yield and Meat Quality of Broiler Chickens
It can be concluded that supplementing the drinking water with an antacid for three days before slaughter improves the carcass and meat quality of broiler chickens by maintaining the pH and water holding capacity of the meat. Expand
The differences of gonadal hormones and uterine transcriptome during shell calcification of hens laying hard or weak-shelled eggs
The study concluded that mammillary thickness and mammillary knob width of the HS were significantly lower than LS, and inferred P4 or 1,25-(OH)2D3 may effect the ultrastructure of the mammillary layer by regulating the expression of uterine genes. Expand
Blood Mineral Response of Local Duck Fed the Diet Containing Seaweed Gracilaria sp. Waste and Additives Multienzyme
The study aimed to evaluate the blood mineral of Tegal ducks as a response to diet containing Gracilaria sp. waste and additive multienzyme. The study used 72 laying ducks of 22 weeks old which wereExpand


Improving eggshell quality at high temperatures with dietary sodium bicarbonate.
Two experiments were conducted that confirmed the hypothesis that a dietary bicarbonate supplement will improve eggshell quality in hens at high temperatures as long as feed is consumed during theExpand
Eggshell quality as influenced by sodium bicarbonate, calcium source, and photoperiod.
Eggshell quality was improved by increasing the photoperiod to 24 hr and was most pronounced when hens were fed diets supplemented with .5% NaHCO3 and limestone as the only source of Ca. Expand
Nutritional and environmental factors involved in egg shell quality of laying hens.
It is suggested that midnight lighting programmes provide a means of supporting egg shell quality of older laying hens during the summer months without a significant reduction in egg production. Expand
The Effect of Feeding Low Chloride Diets with Added Sodium Bicarbonate on Egg Shell Quality and Other Economic Traits
Abstract Diets with and without sodium bicarbonate were fed to commercial Leghorn type hens in an attempt to improve egg shell quality. Trials were conducted with layers housed on the floor and inExpand
Re-evaluation of calcium and phosphorus requirements in aged laying hens
Dietary P content appears to be sufficient for maintaining egg production and shell quality in aged laying hen given 36 to 40 g/kg Ca, and increasing dietary Ca above 40g/kg may require a higher dietary P content. Expand
Laying Performance and Egg Quality of Hens Supplemented with Humate and Sodium Bicarbonate during the Late Laying Period
Abstract Yörük, M.A., Gül, M., Hayirli, A. and Laçin, E. 2004. Laying performance and egg quality of hens supplemented with humate and sodium bicarbonate during the late laying period. J. Appl. Anim.Expand
Physiological changes associated with the production of defective eggshells by hens receiving sodium chloride in the drinking water
1. Supplementing the drinking water of laying hens with 600 or 2000 mg sodium chloride/l induced large increases in egg-shell defects without corresponding changes in egg production, egg weight orExpand

It appears that 0.08% chloride was not adequate for egg production but 0.14% was adequate, and hen-day egg production of the groups fed the lowest level of chloride was significantly lower than production at any of the higher chloride levels. Expand
Dietary interaction of phosphorus with sodium from either chloride or bicarbonate affects laying hen performance.
Experimental diets consisting of two levels of total phosphorus and three different treatments of supplemental sodium affected egg production more strongly than sodium chloride did and addition of sodium bicarbonate to the low phosphorus diet significantly (P less than .05) decreased feed consumption of the hen.

Egg shell quality and cholecalciferol metabolism in aged laying hens.
Results indicate a) that the capacity for expression of 1,25(OH)2D3 in the intestine is not altered by age and b) that prolonged feeding of 1-hydroxylated derivatives of vitamin D3 improves shell quality in aged laying hens and increases culling and mortality. Expand
