优化膳食电解质平衡

Until now, sodium bicarbonate was commonly used to improve sodium content and dEB in poultry feeds. However sodium bicarbonate represents a hidden cost as a source of sodium, 因为它也有很高的缓冲能力. 因此它能中和酸, whether they be acidifiers which are added at a cost or the gastric acids which is vital for optimal digestion.

关于碳酸氢钠的神话
Unfortunately t在这里 are also some myths that have built up around sodium bicarbonate, 通常总结为, “the animal needs bicarbonate to combat a lower blood pH due to heat stress.”

During heat stress poultry increase their rate of respiration during heat stress in an effort to cool down. The net effect of this is expelling CO2 giving an excess of bicarbonate in the blood, increasing pH and ultimately leading to a chronic respiratory alkalosis. 所以事实上，问题是他们的血液pH值太高. 另外, the orally ingested bicarbonate in sodium bicarbonate is neutralized by digestive acids resulting in CO2 and H2O and an increase in pH.

By increasing dEB we increase the sodium that once absorbed acts as a buffer and binds the bicarbonate that is in the blood due to the respiratory alkalosis. In this form (NaHCO3) the animal is able to excrete the excess bicarbonate via the kidneys returning blood pH back to normal. A secondary effect of the higher sodium is that it stimulates the thirst center, 增加饮水量，降低体温. So in fact it is the sodium that the key for handling heat stress and not bicarbonate.

额外的好处-减少抗生素
One of the most common tools available for antibiotic reduction is the use of acidifiers due to their antimicrobial effects. 这些效应只适用于未解离的酸, since in dissociated form the acid is charged and cannot cross cell walls. So, the lower the pH the greater the chance that the acid will occur in undissociated form. Studies support this by showing that the lower the pH in the stomach the greater the antimicrobial effect in vivo as measured by levels of pathogens in the duodenum. 与此形成鲜明对比的是, the same studies have also shown that sodium bicarbonate can actually increase the levels of pathogens like E. 小肠中的大肠杆菌.*1

另外 acids can be added to the diet for their pH lowering effect. It is considered that a low gastric pH is important for the effect of enzymes like pepsin. This is particularly important in young animals whose enzyme and acid production capabilities are immature. To add expensive acidifiers to any diet and then risk losing up to one third of them by adding sodium bicarbonate seems counterproductive to what we are trying to achieve.

During the summer months pathogens are flourishing due to the increase in warmth, 在某些地区也是如此, 也是由于湿度增加. 在柏斯托，我们知道使用proorce™AC 299, 不仅能输送对抗热应激所需的钠吗, 它还具有抗菌作用. Ideal in a situation when the animal is stressed, immunosuppressed and under pathogenic pressure.

The antimicrobial effects of proproce™AC 299 and sodium bicarbonate (SBC) in vitro against S. 鼠伤寒杆菌和大肠杆菌. 在异钠水平下的大肠杆菌.

proproce™AC 299 is sodium formate based and as such offers both a source of rapidly available sodium and formate. 这可能不仅有助于改善dEB, 还有助于维持胃pH值和营养物质的消化率, 同时也是抗菌的. The latter due to the fact that the formate in low pH will occur as formic acid due to the high availability of protons.

选择合适的合作伙伴和十大正规网堵平台
柏斯托是全球甲酸钠生产的领导者, 生产165,我们在世界各地的许多工厂都有1000吨的生产能力. Sodium formate can be derived from different chemical processes giving different product qualities. The majority of these products are only suitable for industrial purposes. W在这里as Perstorp produces the vast majority of the sodium formate suitable to meet the stringent requirement for a feed quality product.

We have selected this high-quality product to produce proproce™AC 299 which is specifically formulated for ease of use in feed production. 这得到了该领域许多满意客户的支持. Today we are in the process of expanding our platform even further to meet the increasing demand for highly effective dry acidifier solutions and sodium bicarbonate replacement.

Perstorp’s 135 year history in organic acids enabled us to be the world leader in production of sodium formate (165,000 tons) and the only company that can realistically offer a competitive solution for dEB, 并支持目标所要求的十大正规网堵平台数量.
