the role and dosage of Sodium bicarbonate in chicken, pig and cattle feed
Sodium bicarbonate(baking soda) is a white crystalline powder, salty, soluble in water, molecular formula is NaHCO3, aqueous solution is weakly alkaline, odorless, commonly known as acidic sodium carbonate, heavy alkali, baking soda or sodium bicarbonate , Oral administration helps digestion, dissolves mucus, neutralizes gastric acid, and has a certain expectorant effect after being absorbed by the body.
Clinically, it is mainly used to neutralize gastric acid, extensive burns, gastrointestinal catarrhal inflammation, sepsis and severe diarrhea, etc. It is widely used in medical and food fields, and is often used as antacids and additives. Sodium bicarbonate can be used as a feed additive with low price, easy operation and good application effect. Adding it to the diet of livestock and poultry can better improve the digestibility of livestock and poultry, accelerate the speed of weight gain, accelerate the absorption of nutrients, and excrete harmful substances. It can improve the body's anti-stress ability, maintain the body's immunity and resistance, prevent diseases, and ensure the growth of livestock and poultry.
1. The mechanism ofaction of sodium bicarbonate
In fact, it is the nutritional and physiological role played by sodium bicarbonate as an electrolyte. The electrolyte balance in the body plays an important role in maintaining water and salt metabolism, osmotic pressure and acid-base balance. Sodium bicarbonate can increase appetite, reduce the viscosity of digestive juice, suppress acid, strengthen gastrointestinal contraction, and strengthen the stomach. Adding an appropriate amount of sodium bicarbonate to the poultry diet can supplement the reduction of carbonate in the blood caused by excessive CO2 exhaled by the poultry, thereby improving the body's calcium metabolism. Sodium bicarbonate can neutralize the organic acid in the stomach and the acidity of silage. It can accelerate the absorption of carbohydrates, cellulose and hemicellulose in the rumen of ruminants, and maintain the stable pH of the rumen at all times, which is conducive to the reproduction of microorganisms and improves the Livestock performance. Sodium bicarbonate can increase the pH and alkali reserve content in the blood, thereby improving the anti-stress ability and buffering ability of livestock and poultry.
2. Application in livestock and poultry production
2.1 Application in chicken production
Adding 0.7% sodium bicarbonate to the diet of broiler chickens over 2 weeks old can increase the weight of broilers by 5%~6%; adding 0.5%~0.8% sodium bicarbonate to the diet of laying hens can make the eggshell thickness Increase by about 6%, reduce egg breakage rate and significantly increase egg weight and egg production; add 0.4% sodium bicarbonate to breeder diet, the fertilization rate can increase by about 5%. If you choose to use sodium bicarbonate instead of table salt, you can significantly improve litter hygiene, reduce broiler drinking water, and reduce the incidence of chest abscesses.
2.2 Application in pig production
Adding an appropriate dose of sodium bicarbonate to the daily diet of piglets can significantly increase the feed intake and daily gain of piglets, and effectively prevent piglets from red, yellow and white scour; The feed consumption rate is significantly reduced, and the daily gain is increased; when 1.2% sodium bicarbonate is added to the diet of sows during lactation or late pregnancy, the body condition of sows is maintained in good condition, and the litter weight of weaned piglets is significantly increased.
2.3 Application in cattle production
Adding 3% sodium bicarbonate to the ration of calves can significantly increase the feed intake and the calves grow rapidly; adding 5% sodium bicarbonate to the ration of beef cattle can significantly shorten the fattening time and improve the utilization rate of feed , to neutralize the acid-base balance of the rumen to prevent excessive acidity; adding an appropriate dose of sodium bicarbonate to the diet of lactating dairy cows increases milk production by 30%, advances the peak milk production and maintains it for 8 months, and improves lactation performance be effectively improved; in the ratio of 6: 4 concentrate and coarse feed rations, the appropriate proportion of magnesium oxide and sodium bicarbonate is mixed and fed to dairy cows, and each cow can increase the production of 3.8 kg of fresh milk every day, especially It is the cows fed silage in the early stage, and the effect is particularly remarkable.
Adding sodium bicarbonate can effectively prevent symptoms such as ruminal acidosis, fatty liver, ketosis and abomasum lesions in dairy cows. Adding 100 grams of sodium bicarbonate to the diet of postpartum non-estrus dairy cows, after continuous feeding for 5 days, the effective estrus rate Reaching more than 90%, it has a significant effect on estrus cows caused by follicle development disorders, persistent corpus luteum and ovary quiescence.
3.benefits of sodium bicarbonatein disease prevention and treatment
Use 2%~3% sodium bicarbonate solution to flush the mucous membrane, which can remove the exposed mucus and reduce inflammation; Intravenous injection of 5% sodium bicarbonate can effectively alleviate it; taking it with streptomycin at the same time can improve the antibacterial effect of the urethra; Sexualizes urine to help excrete nitrates from the body.
4. Matters needing attention
At the beginning of feeding sodium bicarbonate, the poultry will appear anorexia, and it should be gradually transitioned in a small amount and several times, and it can be adapted after about 1 week. The concentration of sodium bicarbonate in drinking water is generally 0.2%~0.3%, and it is easy to decompose in a humid environment, thus affecting the use effect. Therefore, it is best to implement the "three-present" principle, that is, adding, mixing, and feeding, and it is not suitable for long-term storage. , so as not to fail. Organic acids, folic acid, vitamin B, and other substances that are easily destroyed by alkali should be avoided in combination with sodium bicarbonate, and when feeding sodium bicarbonate under high temperature conditions, attention should be paid to controlling the dosage to prevent chickens from eating too much Sodium can cause poisoning. In the actual production process, if improper operation causes excessive sodium bicarbonate, it can be remedied in the following two ways: (1) Increase the ingredients other than sodium bicarbonate in the diet to make it proportionate. (2) It can be neutralized by adding acid or acidic medicine.
