Can adding “her” save 2 kg of dicalcium phosphate? ASB-TP sends shockwaves through the feed industry! Cutting costs without compromising efficacy—the full‑stage solution for low‑nitrogen, low‑phosphorus diets is now available.

Currently, the hog farming industry is facing a compounded impact of multiple cost pressures. Amidst these intertwined factors, controlling production costs has become essential for the survival of farming enterprises. In this wave of rising costs, dicalcium phosphate has seen particularly sharp increases, with prices soaring. 50%-80% , becoming the core pain point of this round of cost increases. Chemical raw materials closely tied to energy prices, such as benzoic acid, phosphoric acid, and organic acids, are also under upward price pressure. This is no longer a fluctuation affecting just a few individual inputs; rather, it is a wave of cost hikes sweeping through the entire industry chain.

Faced with persistently high feed ingredient prices, the industry has gradually developed four main response strategies: reducing dietary protein to cut soybean meal usage (cost reduction and volume decrease), substituting corn and soybean meal with alternative oilseed meals (ingredient substitution), decreasing dicalcium phosphate supplementation and relying on phytase to release phytate phosphorus (enzymatic enhancement), among others.

However, the implementation of these strategies often triggers a chain reaction. A sharp rise in dietary acid load is the starting point of a vicious cycle. ——By-products and high-calcium ingredients cause gastrointestinal pH Environmental degradation leads to reduced protein and phosphorus digestibility, inhibited enzyme activity, and nutrient wastage. Ultimately, this results in declines in both production performance and feed-to-meat ratio. Although the unit price of feed has decreased, the cost per unit of weight gain has risen instead, while intestinal problems have become frequent, increasing medication costs.

The key to breaking this vicious cycle lies in shifting from “pure cost reduction” to “systemic efficiency enhancement.” And the environmental systems that activate enzyme activity both inside and outside the body, releasing the “dormant” key nutrients in feed, are precisely the fundamental levers for improving overall efficiency.

Phosphorus is the third most expensive nutrient in feed; it is not only a high-cost component of production costs but also an essential element indispensable for life processes.

① The foundation of bones and structure: Approximately 85% Body phosphorus exists in the form of hydroxyapatite in bones and teeth, and a deficiency directly leads to problems such as rickets, osteomalacia, and brittle bones.

② The “universal currency” of energy metabolism: Phosphorus is ATP A key component; without phosphorus, energy cannot be stored or utilized.

③ Carrier of genetic information: Phosphorus is DNA and RNA An essential component of the skeleton, it is involved in the transmission and expression of genetic information.

④ Cell membrane structural integrity: Phosphorus is a key component of phospholipids, forming the basic framework of cell membranes.

⑤ Physiological Regulation and Buffer Systems: Phosphorus serves as an activation center for various enzymes, participates in the metabolism of the three major nutrients, and is also a component of the body’s buffer system, helping to maintain acid–base balance.

Precisely because phosphorus plays such diverse and irreplaceable roles in pigs, insufficient supply can trigger a cascade of adverse effects. Meanwhile, among feed costs, the sharp price surge of dicalcium phosphate—the primary phosphorus source—has become a major cost driver in animal husbandry. Consequently, identifying a solution that both supplements phosphorus and enhances its utilization efficiency has emerged as a critical breakthrough for reducing costs and improving productivity.

To verify Aisuanbao TP Regarding the effects during the piglet stage, we conducted a weaned piglet trial. The trial selected 120 head 21 Weaned piglets at a certain age (body weight 6.4±0.6kg ), randomly divided into 3 group, each group 4 Number of replicates, experimental period 14 Day: The control group was fed corn. - Soybean meal-based basal diet; 0.1% Love Acid Protection TP The group was supplemented in the basal diet with 0.1% Love Acid Protection TP ； 0.3% Love Acid Protection TP The group was supplemented in the basal diet with 0.3% Love Acid Protection TP , while also reducing calcium hydrogen phosphate 2kg/T。

The experimental results show that adding Aisuanbao TP Subsequently, the average daily gain of weaned piglets increased significantly, and the feed-to-gain ratio improved markedly; among them, the addition of 0.3% Love Acid Protection TP (while also reducing calcium hydrogen phosphate 2kg/T ) The group showed better outcomes, intragastric pH The value decreased significantly, and the digestive environment was effectively improved. A weaned piglet trial confirmed that AiSuanBao TP It can effectively regulate gastric acidity and promote growth performance as early as the weaning piglet stage, while also enabling cost reductions by decreasing the inclusion of dicalcium phosphate, thereby laying the groundwork for enhanced efficiency in subsequent growing and finishing phases.

The experiment was conducted in Guangdong. NIC The animal experimentation facility was established. The experiment used 80 head 110 Du of age in days × long × Growing-finishing pigs (body weight 63.41±0.21kg , with equal numbers of males and females), randomly assigned according to the principle of similar body weight and consistent male-to-female ratio to 4 Group: ① Control group: fed corn - Soybean meal-based basal diet (normal nitrogen and phosphorus levels) ② Low-nitrogen, low-phosphorus group: Reduce nitrogen and phosphorus levels in the basal diet and supplement with phytase ③ Experiment I Group: Low Nitrogen and Phosphorus - Added to phytase-containing feed 0.1% Love Acid Protection TP ④Experiment II Group: Low Nitrogen and Phosphorus - Added to phytase-containing feed 0.2% Love Acid Protection TP . Each group 4 a repetition, each repetition 5 A pig. The experiment is divided into 60~75kg and 75~100kg The study was conducted in two phases. Slaughter and sampling were performed after the feeding period.

Note: The low nitrogen and phosphorus group is in 60~75kg and 75~100kg Dietary protein was reduced separately in the two phases. 1% , the available phosphorus decreased relatively, respectively 0.04% (Reduce the addition of soybean meal and dicalcium phosphate.)

6.1 Growth Performance — Acid-Tolerant and Resilient TP Ensures weight gain and improves feed conversion ratio.

Diets low in nitrogen and phosphorus often result in reduced growth performance. This experiment found that adding Aisuanbao TP This effectively offset the loss.

6.2 In the stomach pH Regulation—Creating an Environment for Phytase Activation

The primary challenge associated with low-nitrogen and low-phosphorus diets is the alteration of the digestive environment. This experiment found that adding Aisuanbao TP The agent significantly altered the gastric environment. pH Environment.

Figure 3 Add Aisuanbao to the feed. TP To the gastrointestinal tract pH The impact of values

From the figure 3 It can be seen that, compared with the low nitrogen and phosphorus group, the experiment I Group and Experiment II Stomach group pH The value decreased significantly, with the experiment II Stomach group pH The value was significantly lower than that of the control group. Dersjant ‐ Li ( 2015 A review indicates that some microbial-derived phytases in pH 2.5~4.5 It exhibits high activity within the specified range. Meanwhile, the experiment I group and II group's pH Value range ( 3.56~3.47 ) Exactly within this range; in other words, it loves acid and is resistant to TP Inside the stomach pH The regulation has brought it into the optimal activity range of phytase.

Furthermore, an appropriate acidic environment in the stomach helps activate pepsinogen and increase mineral solubility, laying the groundwork for the subsequent digestion and absorption of nutrients.

6.3 Improved Nutrient Digestibility — Direct Evidence of Phytase Efficacy Enhancement

Optimizing the gastric environment leads to improved nutrient digestibility. This experiment found that adding Aisuanbao TP Significantly improved phosphorus digestibility.

Figure 4 Add Aisuanbao to the feed. TP Effect on apparent nutrient digestibility ( 60~75kg Stage)

From the figure 4 It can be seen that the phosphorus digestibility in the low nitrogen and phosphorus group was significantly lower than that in the control group; adding Aisuanbao TP Afterwards, experiment I Group and Experiment II Phosphorus digestibility in the low-nitrogen, high-phosphorus group was significantly higher and had fully recovered to the level of the control group. Crude protein digestibility also showed an upward trend, with all experimental groups exceeding the low-nitrogen, high-phosphorus group.

This result reveals the acid-loving and acid-stable TP The complete process in collaboration with phytase. Under acidic conditions, phytase is efficiently activated and hydrolyzes phytic acid molecules, thereby releasing sequestered phosphorus on the one hand and disrupting the chelation of proteins, amino acids, and digestive enzymes by phytic acid on the other. This is precisely the underlying mechanism responsible for the significant increase in phosphorus digestibility and the improvement in crude protein digestibility observed in the experimental group.

Vötterl Wait ( 2016 ) Studies in growing pigs have shown that acidification can further enhance the hydrolytic efficiency of phytase toward phytate phosphorus. 44.7% . In this experiment, Aisuanbao TP It is precisely through optimizing the stomach environment pH , fully unlocking the potential of phytase.

6.4  Optimizing blood markers—evidence from a metabolic perspective

The improvement in nutrient digestibility is ultimately reflected in blood biochemical parameters. This experiment found that adding Aisuanbao TP Significantly improved serum phosphorus and blood urea nitrogen levels.

Figure 5 Add Aisuanbao to the feed. TP Effect on serum nitrogen and phosphorus levels

From the figure 5 It can be seen that serum phosphorus levels in the low nitrogen and phosphorus group were significantly lower than those in the control group, reflecting insufficient phosphorus intake caused by the low-phosphorus diet. Meanwhile, with the addition of Aisuanbao TP Subsequently, serum phosphorus levels in the experimental group increased significantly, reaching the level of the control group. Regarding serum urea nitrogen, the low-nitrogen–low-phosphorus group showed a significant reduction compared with the control group; the experimental group exhibited an additional significant decrease on this basis.

Serum urea nitrogen is a sensitive indicator of protein utilization efficiency; lower levels generally indicate higher protein utilization. At the same dietary nitrogen level as the low-nitrogen/phosphorus group, the experimental group showed a further significant reduction in urea nitrogen, confirming the effects of Aisuanbao. TP It promotes the digestion and absorption of protein and improves nitrogen utilization efficiency. Meanwhile, the restoration of serum phosphorus levels indicates that the body’s phosphorus homeostasis has returned to normal—directly reflecting the increased release of phosphorus following phytase activation.

6.5 Improvement in bone metabolism markers — calcium-phosphorus regulation is trending toward balance

Changes in bone metabolism markers further confirmed the improvement in calcium and phosphorus metabolism. This experiment found that adding Aisuanbao TP Restores bone metabolism markers to normal levels.

Figure 6 Add Aisuanbao to the feed. TP Effects on bone metabolism markers

From the figure 6 It can be seen that the active vitamin in the low nitrogen and phosphorus group D₃ A significant decrease, with a marked increase in calcitonin, indicates disruption of calcium-phosphorus metabolic balance; addition of Aisuanbao TP After, active vitamin D₃ A significant rebound occurred, and calcitonin returned to normal levels. This indicates that, as phosphate absorption efficiency improved, the organism began to… “ Phosphorus deficiency stress ” The state returns to normal physiological homeostasis.

6.6 Enhancing Environmental Benefits — Dual Emission Reductions from Source to Process

Nitrogen and phosphorus emission reduction is one of the core objectives of this study. The experimental results indicate that Aisuanbao TP It has a significant effect on both source reduction and odor control during the process.

Figure 7 Add Aisuanbao to the feed. TP Impact on nitrogen and phosphorus emissions from manure ( 60~75kg Stage)
 

Figure 8 Add Aisuanbao to the feed. TP Effect on the odor concentration of fermented manure ( 75~100kg Stage)

From the figure 7、8 It can be seen that nitrogen derived from manure in the low-nitrogen and phosphorus group was significantly lower than in the control group; the experiment I Nitrogen from fecal sources was further significantly reduced in the low-nitrogen–phosphorus group. Regarding phosphorus from fecal sources, the experimental group showed a decreasing trend, demonstrating a dose‑related additive improvement effect. As for fecal odor, fecal fermentation 8h At that time, the ammonia concentration in the experimental group was significantly lower than that in the control group.

Ammonia production primarily results from the microbial decomposition of nitrogen-containing organic matter in manure, while urease exhibits high activity only under neutral to alkaline conditions. The reduction in odor observed in the experimental group may be associated with Aisuanbao. TP Regarding feces pH Its regulation inhibits urease activity. Overall, Aisuanbao TP By activating phytase and improving nitrogen and phosphorus use efficiency, source‑level reductions in nitrogen and phosphorus emissions were achieved; at the same time, fecal fermentation odors were reduced to some extent ( NH ₃ ), demonstrating environmentally friendly emission reduction outcomes.

6.7 Production Efficiency Analysis — The Ultimate Validation of Cost Reduction and Efficiency Gains

Beyond environmental protection, economic benefits are equally a key criterion for assessing the feasibility of a plan.

In the low nitrogen and phosphorus group, feed costs were lower than in the control group due to reduced use of soybean meal and dicalcium phosphate, resulting in overall feed cost savings over the entire trial period. 5.6 Yuan. Add Aisuanbao on this basis. TP Subsequently, although the unit price of feed rebounded slightly, the overall economic benefits improved further due to enhanced growth performance and reduced feed consumption. 0.1% Love Acid Protection TP The total feed consumption over the entire experimental period was lower than that of the control group. 2.7kg , total feed input was reduced compared to the control group 9.2 Yuan, the unit cost of weight gain from the control group was 11.0 yuan /kg Drop to 10.6 yuan /kg . This means that for every length 1 Kilograms of meat, reduced costs 0.4 Yuan.

Optimization of production efficiency stems from two aspects: first, the low-nitrogen, low-phosphorus diet itself reduces raw material costs; second, Aisuanbao TP By activating enzyme activity, it significantly enhances the efficiency of nitrogen and phosphorus utilization and improves feed conversion efficiency, achieving sustained productivity gains while reducing costs. The synergistic effect of these two factors ultimately translates into substantial economic returns!

Conclusion

 

Overall, adding Aisuanbao to a low-nitrogen, low-phosphorus diet (containing phytase) TP , replacing two kilograms of calcium hydrogen phosphate can achieve a systemic upgrade—from cost reduction to increased efficiency and emission cuts—while ensuring growth performance!
