1 Coated calcium chloride Protected anionic mineral supplement for animal nutrition Sintoclor CATION-ANION BALANCE

2 APPLICATION OF ANIONIC SALTS IN ANIMAL NUTRITION As factor of electrolytic equilibrium of the organism with particular reference to the cation-anion balance C.A.B. Cation-Anion Balance

3 When the balance between cation and anion result in a net negative charge blood pH is lowered. To neutralize the lower blood pH caused by negative DCAD, the animal mobilizes buffers including Ca phosphate and bicarbonate from bone. The metabolic manipulation normally leads to lower urine pH. Urinary pH is a good indicator of susceptibility to parturient hypocalcemia and the effectiveness of DCAB adjustment. Using the correct DCAD a urine pH of 6 to 6.5 will be achieved. Cation-Anion Balance (CAB)

4 C.A.B.

5 Suggested DCAD (dietary cation-anion difference) values

6 Acidogenic potency of feedstuffs Mineral content of some feedstuffs (% dm)

7 Acidogenic potency Quick calculation

8 Metabolism Ammonium sulphate (NH 4 ) 2 SO 4 Metabolic problem Epsom salts MgSO 4 Bad absorption Calcium sulphate (gypsum) CaSO 4 Bad absorption Calcium chloride CaCl 2 Off flavour, risk of rumen acidosis Ammonium chloride NH 4 Cl Metabolic problem Physiological and sensorial estimation of acid salts

9 MAIN MINERAL SALTS USED TO BALANCE THE CAB Calcium chloride Magnesium sulphate Ammonium chloride

10 Calcium chloride is one of the best source of anionic salts for transition cows and pre-farrowing sows. Double action calcium salt. Good source of calcium at very low acid-binding capacity and high bio-availability Cl - anion (>90%). It can achieve the correct level of cation-anion balance and in this way the calcium requirements will be met without mineral restriction. Relative Potency of Acidogenic Substances CaCl 2 Calcium chloride

11 Relative Potency of Acidogenic Substances The effectiveness of MgSO 4 as an acidifier is arguable. Mg supplementation might be beneficial in cows fed NH 4 Cl 2 if the basal Mg intake is marginal. Ammonium salts may impair Mg utilization, thereby producing a secondary magnesium deficiency. MgSO 4 - magnesium sulfate Dietary supplementation with Mg might help prevent this adverse effect of ammonium salts and might also help counteract impairment of magnesium absorption associated with high dietary potassium.

12 Relative Potency of Acidogenic Substances NH 4 Cl - ammonium chloride Ammonium chloride is acidogenic because the NH4 + ion dissociates into NH 3 and H +, and the NH 3 can be converted to urea in the liver. Ammonium salts may impair Mg utilization thereby producing a secondary magnesium deficiency. Not included in the feed materials list of EU (excluding France only for fattening lamb). Waste of energy.

13 Relative Potency of Acidogenic Substances On the basis of data referred to the acidogenic potency, calcium chloride is the most active but it shows palatability and handling problems during feed production A protection technology is necessary for an efficient use in order to avoid all negative factors

14 COATED CALCIUM CHLORIDE Why? Negative factors Highly hygroscopic Very soluble Unpalatable Irritation of mucosa Risk of acidosis

15 Technology of protection W.R.C.® (Water Releasing Control) Protection coating Slow release Main target small intestine

16 Hygroscopicity: comparison between CaCl 2 and SINTOCLOR products exposed to air, observed under the microscope Granular calcium chloride at time 0 SINTOCLOR at time 0

17 SINTOCLOR after 4 min Unlike SINTOCLOR, CaCl 2 begins to adsorb humidity already after 4 minutes of exposure to air. Hygroscopicity: comparison between CaCl 2 and SINTOCLOR Granular calcium chloride after 4min products exposed to air, observed under the microscope

18 SINTOCLOR after 6 min Humidity penetrates into the granule of CaCl 2, while it remains adhering to the surface of SINTOCLOR without penetrating. The granule is translucent, as it is absorbing water Hygroscopicity: comparison between CaCl 2 and SINTOCLOR products exposed to air, observed under the microscope Granular calcium chloride after 6 min

19 SINTOCLOR after 20 min After 20 minutes of exposure to air the described phenomena continue. Hygroscopicity: comparison between CaCl 2 and SINTOCLOR products exposed to air, observed under the microscope Granular calcium chloride after 20 min

20 SINTOCLOR after 30 min After 30 minutes of exposure to air CaCl 2 is completely surrounded unlike SINTOCLOR, where small water drops are forming only on the surface. Hygroscopicity: comparison between CaCl 2 and SINTOCLOR products exposed to air, observed under the microscope Granular calcium chloride after 30 min

21 products wet with water, observed under the microscope Calcium chloride and SINTOCLOR have been placed on a slide, a coffee spoon of water was added and observed under the microscope. Immediately after the contact with water, CaCl 2 begins to dissolve while SINTOCLOR remains unaltered. SINTOCLOR at time 0 Hygroscopicity: comparison between CaCl 2 and SINTOCLOR Granular calcium chloride at time 0

22 SINTOCLOR after 1 minute CaCl 2 continues dissolving, causing an increase of water temperature, while SINTOCLOR remains unaltered. Hygroscopicity: comparison between CaCl 2 and SINTOCLOR products wet with water, observed under the microscope Granular calcium chloride after 1minute

23 SINTOCLOR after 2 minutes Hygroscopicity: comparison between CaCl 2 and SINTOCLOR products wet with water, observed under the microscope Granular calcium chloride after 2minutes CaCl 2 continues dissolving, causing an increase of water temperature, while SINTOCLOR remains unaltered.

24 After 5 minutes CaCl 2 has completely dissolved, while SINTOCLOR microgranules only show small water drops at the surface. SINTOCLOR after 5 minutes Hygroscopicity: comparison between CaCl 2 and SINTOCLOR products wet with water, observed under the microscope Granular calcium chloride after 5 minutes

25 SINTOCLOR wet with water, observed under the microscope after 30 minutes The water drop cannot penetrate the granule of SINTOCLOR and remains on the surface Hygroscopicity: comparison between CaCl 2 and SINTOCLOR

26 SINTOCLOR wet with water, observed under the microscope after 120 minutes Hygroscopicity: comparison between CaCl 2 and SINTOCLOR
