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 the period of eggshell formation. End-of-lay hens were maintained on continuous light at temperatures of 30 and 35 C. Individual egg weights and shell quality measures for each hen were calculated as a pr...
متن کاملDietary Amino Acid and Sodium Bicarbonate Responses in Broilers Reared in Hot Environmental Temperatures
Better environmentally controlled broiler houses have resulted in many integrated broiler operations using the same dietary feed formulations in winter and summer months due to only minor differences in environmental temperature in the broiler house. Much research has addressed broiler nutrient needs in thermoneutral vs. hot temperature conditions, but research evaluating nutrient needs of broi...
متن کاملEHects of dietary sodium bicarbonate on egg production and egg quality of laying hens during high summer temperature
Eggshell quality is one of the most common problems in layer stocks. Results from the field have shown that the incidence of cracked eggs in layer stocks ranges from 1-2% to 30-35% (ALTAN and ALTAN, 1992). This problem is more specific in older flocks when the birds were raised under high environmental temperatures. The eggshell consists of 98% calcium carbonate. The necessary Ca for shell form...
متن کاملEggshell Quality is Improved by Excessive Dietary Zinc and Manganese
640 Hy-Line W36 white Leghorn laying hens regarding their ages (28 and 44 weeks) were divided into two 64 groups of 5 bird per cage (16×4 factorial test). 16 experimental diets included a corn soybean meal basal diet containing 50mg/kg Zn and 30mg/kg Mn supplemented with 0-0, 0-30, 0-60, 0-90, 50-0, 50-30, 50-60, 50-90, 100-0, 100-30, 100-60, 100-90, 150-0, 150-30, 150-60 and 150-90 mg/kg of Zn...
متن کاملSodium bicarbonate
Major uses Sodium bicarbonate is a main constituent of baking soda/powder. Baking powder is composed of 30% of sodium bicarbonate, with cornstarch, sodium aluminium sulfate, calcium acid phosphate, and calcium sulfate [1]. Sodium bicarbonate may be an ingredient of folk remedies containing turpentine, castor oil, lemon and sugar. It is also added to mouthwashes and dentifrices to prevent dental...
