Definitions
- Raw material for animal nutrition comprising an organo-mineral complex containing food phosphate and a humic substance
- the invention relates to a new raw material containing phosphate intended for animal feed.
- This new raw material combines feed phosphate with an organic compound in the form of an organo-mineral complex, which makes it possible to increase the digestibility of inorganic phosphorus in the diet of farm animals, and which has beneficial effects on certain biological effectors.
- Phosphorus (P) is a chemical element essential to life on earth. It participates in the proper functioning of the metabolism of many organisms, fauna and flora such as human beings, animals, micro-organisms or plants, by intervening in the energy processes (production of adenosine triphosphate, ATP), in bone and dental synthesis, in the composition of deoxyribonucleic (DNA) and ribonucleic (RNA) acid, in the composition of cell membranes (phospholipids, etc.) and in the regulation of blood acidity.
- ATP adenosine triphosphate
- DNA deoxyribonucleic
- RNA ribonucleic
- cell membranes phospholipids, etc.
- P is therefore an essential element for the good health of animals and for the productivity of farms. It is necessary to add mineral phosphorus to the feed ration of livestock in order to improve animal weight gain, milk production, bone mineralization and fertility.
- a deficiency in dietary P can disrupt milk production, feed consumption and animal performance and lead to a state of latent acidosis which, despite dietary intake, is not resolved until salivation does not is not sufficient.
- the solubility of the source is not a determining factor in managing this disorder.
- the ruminant system will draw on their P reserves, namely the P stored in the tissues or in the bones. This type of short-term deficiency in early lactation is not a problem if it is corrected quickly before the start of the 2nd stage of lactation, as in the case of calcium (Ca) metabolism.
- the raw material of the invention contains a food phosphate and a humic substance, such as humic acid, fulvic acid or humates.
- Humic substances are commonly used to improve the digestibility of the ration.
- the prior art has already described food or food raw materials containing humic substances and calcium phosphate, such as for example the patent application CN109198275, which proposes a raw material to improve the nutritional balance of carp and promote their growth.
- the calcium phosphate is not complexed with the humic substance, since they have not been reacted together. The two compounds are simply dry mixed and ground so that the complex cannot form.
- patent application CN109198275 does not deal with the problem of bioavailability of phosphorus in animals.
- the invention solves these problems and meets these needs by proposing a food raw material for animal nutrition comprising an organo-mineral complex containing food phosphate and a humic substance, said humic substance engaging physico-chemical bonds with atoms, such as for example calcium atoms, and/or with the phosphorus atoms of food phosphate.
- a food raw material for animal nutrition comprising an organo-mineral complex containing food phosphate and a humic substance, said humic substance engaging physico-chemical bonds with atoms, such as for example calcium atoms, and/or with the phosphorus atoms of food phosphate.
- the inventors have in fact found, surprisingly, that the humate-phosphate complex confers an improvement in the effects of phosphate compared with the results recorded, when the latter is used alone. These effects relate in particular to zootechnical performance, the digestibility of phosphorus in the ration and the regulation of certain biological effectors.
- the inventors have in fact shown that the nutritional properties of phosphorus of mineral origin can be improved by complexing it with a humic substance.
- the inventors believe that, in the case of calcium phosphate, the complexation of calcium with the humic substance makes it at least partially unavailable in the digestive tract and thus makes it possible to increase both efficiency of phosphorus digestion and efficiency of phytase activity.
- the raw material of the invention thus makes it possible to reduce the necessary dose of phosphate and/or the necessary dose of phytases in food.
- the present invention stems from the surprising advantages demonstrated by the inventors of the effect of complexation by humic substances of calcium and/or phosphate ions on the bioavailability of phosphorus during digestion in a monogastric animal.
- the digestibility of inorganic phosphorus is in fact improved by using a complex between mineral P and an organic molecule based on humic substance, in particular humates or humic acids. This leads in particular to better digestibility of the ration (and of phosphorus in particular) for all species, better bone mineralization (for chickens and hens, for example, which reduces lameness in breeding and delays the culling of layers) and better eggshell quality (for hens) which reduces egg downgrade rate and increases hatchability and chick viability.
- the raw material of the invention also brings benefits for breeders, since it allows a saving of ingredients and an increase in productivity.
- the fact of binding calcium with a humic substance limits many reactions of this cation with the other elements present in the digestive tract. These reactions are indeed often sources of loss of performance.
- the raw material of the invention therefore leads to better efficiency of the ration, and thus reduces phosphorus discharges into the environment.
- the food raw material allows zootechnical performance to be maintained if it is incorporated at a dose making it possible to reach 80% of the usual phosphorus requirements.
- the raw material of the invention also makes it possible to fight against mycotoxins because it is capable of adsorbing them at different pH during digestion.
- the organo-mineral complex is capable of adsorbing some of the aflatoxins and other mycotoxins initially present in the ration.
- the food raw material for animal nutrition may comprise an organo-mineral complex based on food phosphate and a humic substance, said humic substance being able to engage physico-chemical bonds with phosphorus atoms of the food phosphate.

- the organo-mineral complex is a matrix of calcium phosphate comprising from 0.5% to 15% by mass, preferably from 1.0 to 2.5% by mass of humates relative to the mass of calcium phosphate and humates.
- the humic substance can initiate chemical bonds with some or all of the phosphorus atoms of the food phosphate: the phosphorus can be complexed with the humic substance.
- the complexation of phosphorus with the humic substance in the organo-mineral complex can be demonstrated by any method known to those skilled in the art, in particular by X-ray diffraction (XRD) or phosphorus-31 nuclear magnetic resonance (NMR 31 P ).

- aqueous solutions of sodium humates with a variable concentration of humates ranging from 100 g/L to 250 g/L are prepared by dissolving the sodium humates in water, preferably water heated to 50°C.
- Sodium humate (CAS number 68131-04-4) is commercially available under the reference Nut Mordan® manufactured by the company Humatex.
- the pH of this product diluted at 10% in water is between 10.0 and 12.0 and its humic acid content by dry weight is greater than 60%.
- the content of humic acids by dry weight is equal to the complement to 100% of the ash content measured after calcination of the sample in an electric furnace at 500°C for 60 minutes and at 805°C-825°C for 60 minutes (according to the manufacturer).
- Each aqueous solution of humates is then poured with stirring into the phosphoric acid solution, stirring being maintained to disperse the solid formed and the temperature maintained at 50°C.
- Calcium carbonate (having a total CaO content greater than or equal to 53%) is then poured into the dispersion, then the mixture is stirred vigorously, lumped together, granulated and then dried.
- phosphoric acid is not diluted in water, and it is poured simultaneously with the solution of sodium humates on calcium carbonate.
- the mass ratio between undiluted phosphoric acid at 54% P 2 O 5 in water and calcium carbonate was 2.5 to manufacture MCP.
- MCPH10 monocalcium phosphates containing 1.0% (noted MCPH10), 1.5% (noted MCPH15), 2.0% (noted MCPH20), 2.5% (noted MCPH25), 5.0% (noted MCP50) and 10.0% (denoted MCP100) of humates could be prepared.
- Dicalcium phosphates containing 0% (denoted DCP), 1.0% (denoted DCP10), 5.0% (denoted DCP50) and 10.0% (denoted DCP100) of humates by applying a mass ratio [phosphoric acid at 54%P 2 O 5 / calcium carbonate] 1.3. could also be prepared. In most of the tests, and in order to limit the number of invention samples studied, the choice fell on doses between 1.0% and 2.5%, preferably 1.5%.
- a diffractometer X'Pert Pro, PANalytical brand
- In the path of the X-ray beam were mounted as primary optics Soller slits of 0.04 rad, a divergence slit of 1/16°, a mask of 10 mm, an anti-scattering slit of 1/8°, and as secondary optics, a Nickel filter and Soller slits of 0.04 rad. After fine grinding, the samples were compacted in a rear-loading sample holder.
- the peaks of the MCPH15 diffractogram reveal that this sample mainly contains monocalcium phosphate monohydrate (Ca(H 2 PO 4 ) 2 .H 2 O), probably anhydrous dicalcium phosphate (monetite Ca(HPO 4 )) and possibly calcite ( calcium carbonate; CaCO 3 ) and anhydrous monocalcium phosphate (Ca(H 2 PO 4 ) 2 ( Figure 2).
- the diffractogram of MCPH15 shows less intense diffraction peaks than that of MCPH0, which indicates that this sample is less crystallized.
- the samples were introduced (packed) into a cylindrical sample holder (rotor) made of zirconium oxide 4 mm in diameter closed by a Kelefl® stopper.
- the 31P MAS spectra were recorded at a rotation speed of 12kHz with a pulse angle equal to a duration of 3 microns and a recycling time of 200s.
- the chemical shifts are expressed relative to an 85% aqueous solution of H 3 PO 4 . After analysis, the samples were fully recovered.
- Figure 4 shows the superposition of the 31 P-NMR spectra of the two samples analyzed. More precisely, Figure 5 shows that after deconvolution, the spectrum of MCPH0 presents four signals at 0.75, -0.15, -1.45 and -4.65 ppm.
- the signals at -0.15 and -4.65 correspond to the presence of monocalcium phosphate monohydrate (Ca(H 2 PO 4 ) 2 .H2O) major compound (80%), as demonstrated by XRD analysis.
- these two signals correspond to two H 2 PO 4 ' groups which are differentiated, that at -4.65 being an acceptor of hydrogen bonds with the protons of the water molecule while that at - 0.15 would be a donor of a hydrogen bond .
- the two broader signals at -1.45 and 0.75 ppm characterize the crystallographic sites of dicalcium phosphate (CaHPO 4 ) not revealed by XRD and in a minority quantity in this sample (20%).
- Figure 6 shows that after deconvolution, the spectrum of MCPH15 presents five signals at -0.1, -0.2, -1.75, -4.75 and -10.0 ppm.
- the characteristic signals of monocalcium phosphate monohydrate (Ca(H 2 PO 4 ) 2 .H2O) are observed at -0.2 and -4.75 ppm but in a lower proportion (40% of the sample) , their corresponding peaks being weaker than for MCPH0.
- the peak at -1.75 ppm corresponds to the peak at -1.45 ppm of MCPH0, it is therefore the presence of dicalcium phosphate (CaHPO 4 ), up to 10%.
- the signal at - 0.1 ppm particularly wide would correspond to the superposition of several elements chemicals, namely: the missing part of monocalcium phosphate monohydrate (Ca(H2PO4)2.H2O; i.e. 20%), the invisible resonance of this dicalcium phosphate (CaHPO 4 ; i.e. 10%) and a hidden part of anhydrous monocalcium phosphate ( Ca(H 2 PO 4 ); up to 5% to 10%) the only phosphate component whose chemical shifts can be found in the region around -0.1 ppm.
- the very broad signal between -6.0 and -12.0 ppm corresponds to amorphous p-Ca 2 P 2 O 7 type pyrophosphates, present at about 15% in the sample.
- This amorphous characteristic is highlighted by the width of the signal which indicates that the environment of the P is very unordered and therefore modified.
- This peak reflects the new environment of phosphate bound by Ca-humic acid binding sites, highlighting the complexation of humic acids with minerals (Ca or P). The widening of these two peaks, revealing amorphous phases, highlights a chemical reaction between the sources of phosphorus and the humates indicating the presence of complexes.
- the results of the XRD and 31 P NMR analyzes of the two samples are consistent and complementary.
- the two methods confirm the presence of crystallized monocalcium phosphate monohydrate (Ca(H 2 PO 4 ) 2 .H 2 O).
- the 31 P NMR makes it possible to highlight the presence of dicalcium phosphate otherwise called monetite (CaHPO 4 ) in the MCPH0 and probably in amorphous form (broad signals at -1.45 and 0.75 ppm of the NMR) because not detected in XRD. This means that the 3 unidentified peaks beyond 64° do not correspond to this monetite.
- the 31 P NMR makes it possible to confirm the presence of crystallized phases observed in XRD, namely: monocalcium phosphate monohydrate (Ca(H 2 PO 4 ) 2 .H 2 O) which is predominant followed by monetite (CaHPO 4 ).
- 31 P NMR also highlights the presence of a new species, calcium pyrophosphates (p-Ca 2 P 2 O 7 ) which are in amorphous form since they are not identified by XRD.
- the 31 P NMR makes it possible to evaluate in a very relative way the distribution of phosphorus in the following way: majority phase, more than 50% of Ca(H 2 PO 4 ) 2 .H 2 O, several minority phases (less than 50%) were identified from CaHPO 4 , amorphous pyrophosphates and partially crystallized Ca(H 2 PO 4 ) 2 , also an amorphous phase represented by the broadening of the spectra (curves) corresponding to our organo-mineral complex.
- the two XRD and NMR analyzes reveal the presence of amorphous phases equivalent to an organo-mineral complex resulting from chemical reactions in the medium between humic acids and inorganic compounds (calcium phosphates).
- Example 2 In vitro test on an artificial fermenter: impact of the product of the invention on the fermentation parameters
- a test in an artificial fermenter was carried out with the four products of invention MCPHO, MCPH10, MCPH5 and MCPH100 prepared according to Example 1.
- the principle of artificial fermentation is based on the incubation of rumen juice under anaerobic conditions at 39°C (Menke and Steingass, 1988).
- the bacterial flora in the presence of the appropriate substrate reproduces ruminal fermentations, which makes it possible to monitor gas production as well as end products such as volatile fatty acids (VFA), N-NH 3 etc. depending on the objectives of the study.
- the device consists of 21 250ml bottles containing 150ml of an inoculum based on rumen juice and buffered artificial saliva (1:2). This inoculum is incubated under anaerobic conditions at 39°C without substrate (White) or with 1.25g of substrate (corn silage, hay, concentrate: 50/30/20, provides 2.2g of P/kg) alone (Control CT) or with the substrate added with the appropriate dose of each product tested to have an identical phosphorus supply (MCPHO to MCPH100).
- the vial sampling system will allow kinetics to be carried out at 2h, 4h and 6h30. Table 1 recalls the experimental design of the trial.
- FIG 8 shows that the VFA concentrations increase over time (p.val ⁇ 0.001). Certain treatments in particular tend to increase the production of total VFAs compared to Control CT (p.val ⁇ 0.10).
- MCP supplementation increases the production of VFAs and the formulas with 1% and 10% humic acids promote this effect (p.val ⁇ 0.01).
- Example 3 In vitro monogastric digestion test: impact of the product of the invention on the digestibility of the minerals Ca. P and Mq
- the present in vitro digestion test aims to evaluate the digestibility of the Ca, P and Mg minerals of the invention products of Example 1. In order to confirm the results, the test was repeated once.
- the results of the two in vitro tests carried out are presented as follows: test 1 and test 2 below.
- the device used is a Bain-Marie composed of 15 places that can each accommodate a 50 ml Eppendorf tube each containing a food sample of 1.0 g.
- the samples are incubated at 40°C.
- a test takes place in 3 stages in order to mimic the digestion of growing chickens, in the crop (amylase, pH: 5.8, duration: 35 min), then the succenturiate ventricle (pepsin, pH: 2.7, duration: 42 min) and finally in the intestine until the ileal phase (pancreatin, pH: 6.5, duration: 170 min).
- Nine tubes are used to receive samples of complete feed for growing chickens which contain the products of the invention at the following doses of humates: 0% and 1.5%.
- the solubility of calcium is significantly higher by 3 points in the presence of 1.5% humates than in its absence.
- Example 4 In vitro study of the adsorption capacity of mvcotoxins by the product of the invention in the digestive tract of monoaastrigues
- the purpose of the present in vitro study is to evaluate the mycotoxin adsorption capacity of the product of the invention under the conditions of digestion of monogastrics.
- the principle consists in bringing the product into contact with a given dose of mycotoxins at a given temperature and pH.
- mycotoxins were chosen according to the recurrence of their presence in food or vegetable raw materials intended for monogastrics but also according to the sensitivity of poultry and pigs (young and adult) towards them.
- the dose of each of these four mycotoxins was determined according to European regulations (aflatoxin B1) and the sensitivity of the two species (zearalenone, ochratoxin A and deoxynivalenol).
- aflatoxin B1 European regulations
- zearalenone, ochratoxin A and deoxynivalenol three doses (0.5%, 0.8% and 1.0%) of the product of the invention MCPH15 were brought into contact with 100 to 900 ng/ml of mixed mycotoxins (Table 4).
- the mycotoxin concentration was measured after each incubation time to determine the quantity adsorbed by the product.
- Mycotoxin concentrations were measured by UHPLC-MS/MS. Specifically, a buffered phosphate solution was prepared at 0.1 M at pH 2.50 ⁇ 0.05 (average stomach pH between pig and poultry) and spiked with mycotoxins at the concentrations listed above. The sample was added to the mycotoxin enriched solutions and the suspension was then incubated at 40°C for 1 hour. The suspension was then centrifuged and the supernatant was sampled. The remaining supernatant was discarded, and the test material was then resuspended in a solution of 0.1 M buffered phosphate at pH 6.80 ⁇ 0.05 (average testin pH between pigs and poultry) before being incubated at 40° C. for an additional 3 hours.
- Example 5 - Test 1 in vivo on meat poultry effect of the product of the invention on performance, metabolism and meat quality
- the feed was made to order with the incorporation of the products tested during the mixing of the raw materials.
- the food does not contain microbial phytase and the raw materials chosen are low in endogenous phytases.
- Products tested monocalcium phosphates with or without humates.
- the doses of humates in the product of the invention vary from 1.0 to 2.5%.
- Example 6 In vivo test on meat poultry: effect of the product of the invention on the performance, the quality of the legs and the litter
- Zootechnical test on 16 cages of 30 male chickens in a conventional breeding building with a minimum prevalence of 70% in pododermatitis and a standard consumption index (IC 1.50 at D35 and 1.65 at D42).
