It refers to soda ash (sodium carbonate) and baking soda (sodium bicarbonate) different from industrial alkali. Baking soda is the finished product after absorbing carbon dioxide from soda solution or crystal, and there is no difference between them in essence. So baking soda is also called edible alkali (powder) in some places Baking soda is solid, round, white and easily soluble in water.

Action mechanism of sodium bicarbonate (baking soda)
1. Sodium bicarbonate can neutralize gastric acid, dissolve mucus, reduce the viscosity of digestive juice, strengthen the contraction of gastrointestinal tract, and play a role in invigorating stomach, inhibiting acid and stimulating appetite.
2. Adding sodium bicarbonate to feed can supplement the decrease of carbonate in blood caused by poultry's heat wheezing (excessive CO2 exhalation), thus improving the body's calcium metabolism.
3. Adding sodium bicarbonate to feed can improve the fluidity of phosphorus in laying hens. In order to form a good eggshell, it is necessary to maintain an appropriate phosphorus concentration in the blood. Sodium bicarbonate can keep the blood night phosphorus concentration of laying birds at the optimal level necessary for eggshell formation.
4. Sodium bicarbonate can decompose and release CO2 in the digestive tract, thus taking away a lot of heat, which is beneficial to maintain the thermal balance of the body when it is hot.
5. Adding sodium bicarbonate to feed can provide sodium source, so that the blood can keep proper sodium concentration. In the feed for laying hens, sodium is 0. 14%-0.28% and chlorine is 0.20%-0.24%. The ratio of sodium to chlorine is appropriate, and the egg laying rate, egg weight, eggshell formation and feed efficiency are all good. The suitable mineral levels of broiler feed are sodium 0. 15%-0.20%, potassium 0.80% and chlorine 0. 12%-0. 15%. However, it is difficult to balance sodium and chlorine in feed with sodium chloride, and the increase of choline chloride dosage aggravates the imbalance of sodium and chlorine.
Application effect of sodium bicarbonate in poultry feed
1. Laying hens: Adding proper amount of sodium bicarbonate to the diet of laying hens in summer can improve the laying rate and eggshell strength. The experiment shows that when the ambient temperature rises 1℃ at 25-30℃, the laying rate decreases 1.5% and the egg weight decreases by 0.3g If it is higher than 22℃ for a long time, the eggshell will become thinner and the egg weight will decrease. Ran Rujun et al. (1990) conducted an experiment with 53-week-old laying hens in summer. Each layer in the experimental group added 0.3g sodium bicarbonate to the basic diet (containing 0.2% salt) every day, while the control group did not add sodium bicarbonate, and the diet contained 0.3% salt. Results Compared with the control group, the egg laying rate, eggshell density, eggshell percentage and eggshell thickness of the experimental group increased by115%, 0.20%, 1. 10% and 3.57%, respectively, with significant differences in egg laying rate (P Liu Shenting et al. (1987) used Beijing white layers and added 0.5% sodium bicarbonate to the summer diet. As a result, the laying rate increased by 3.3%, the eggshell quality increased by 0.55%, and the blood alkali storage increased by 45 mg/L.
Zhou Ming (1996) studied the appropriate ratio of chloride and bicarbonate in the diet of laying hens in high temperature season. Adding 0.2% sodium chloride (0.35% total chloride in the diet) and 0.2% sodium bicarbonate (0.38% total bicarbonate in the diet) to the diet of laying hens in high temperature season can significantly improve the egg laying rate, eggshell quality and feed conversion rate (P < 0.0 1). The suitable ratio of chloride to bicarbonate in laying hens' diet is 35: 38.
According to the research of ICI Company (1988), different levels of sodium bicarbonate of 0. 1%- 1.0% were added to the feed of laying hens for 8 months. The results showed that the egg laying rate of each group was improved by adding sodium bicarbonate, and the eggshell strength was increased by 8% at the highest. Adding 0.3% sodium bicarbonate to the standard feed for laying hens, after adding the peak of laying hens, the downward trend of laying rate with the increase of day age was alleviated, and the number of broken eggs decreased by 1%-2%. They also studied the interaction between sodium bicarbonate and phosphorus. When the sodium content of sodium bicarbonate in feed is 0.55%, the phosphorus content is 0.30%, and the laying rate is 75%. The phosphorus content is 0.75% and the egg laying rate is 77%. The experimental results also show that due to the addition of sodium bicarbonate, the utilization rate of nitrogen will increase by 3%.
2. Laying ducks: Wu Lingqian et al. (1998) reported that adding 0.4% sodium bicarbonate to the diet of laying ducks in midsummer, while reducing the salt consumption from 0.3% to 0. 15%, the laying rate increased by 5.8%, with significant difference (P < 0.05); The broken rate and death rate of soft eggs decreased significantly, and the difference was extremely significant (P < 0.05438+0). Feed reward increased by 6.8%, with significant difference (P < 0.05).
3. Broiler: Adding 0. 1%-0.5% sodium bicarbonate to broiler feed has obvious effect on improving broiler carcass grade and weight gain. British researchers reported that using sodium bicarbonate instead of sodium chloride as the sodium source in broiler feed reduced the amount of drinking water and improved the padding conditions. When the sodium content in the diet was 0. 12%-0.28%, the weight of 4-week-old broilers was 889g in the sodium bicarbonate diet group and 86 1 g in the sodium chloride diet group, and the difference was significant through variance analysis. Adding sodium bicarbonate to broiler feed can also reduce mortality and the incidence of some diseases. Irving (1994) and other studies show that adding sodium bicarbonate to corn-soybean practical diet can alkalize the diet and greatly reduce the incidence of ascites. In the high altitude environment (simulating the low pressure chamber at an altitude of 3000m), 42% of broilers fed with basic diet died of ascites, while only 24% of broilers fed with 1% sodium bicarbonate died of ascites, and the mortality rate was significantly reduced. According to Phelps( 1989), adding 10g sodium bicarbonate to broiler feed containing 90g fish meal per 1kg significantly reduced the incidence of myogastric erosion. The research of Yamanashi Livestock Farm (1990) in Japan showed that when the shed temperature was above 28℃, the mortality rate was 4.88% when adding 0.63% sodium bicarbonate to the diet of 42-63-day-old broilers, while the mortality rate of the group without sodium bicarbonate was 7.85%. Considering maintaining the acid-base balance of chickens, adding sodium bicarbonate can reduce the death caused by heat shock.
