Abstract
Abstract The method of preparing bovine colostrum for use in treating livestock comprising the steps of: 1. Collecting bovine colostrum milk: 2. Removing substantially all of the fat from the colostrum milk: 3. Removing the casein from the colostrum milk to obtain bovine colosteral whey: 4. Dializing the whey: 5. Adjusting the pH of the dialsate to 4.0 to 4.5: 6. Precipitating the whey: 7. Removing the supernant from the precipitated whey: 8. Clarifying the supernant: 9. Adding a water, saline and phenol mixture to the clarified supernant to obtain the desired concentration: 10. Sterilizing the mixture; and 11. Placing the sterilized mixture into containers for subsequent storage and use.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
96 words
The method of preparing bovine colostrum for use in treating livestock comprising the following steps, collecting bovine colostrum milk, removing substantially all of the fat from the colostrum milk, removing the casein from the colostrum milk to obtain bovine colosteral whey, dializing the whey, adjusting the pH of the dialsate to 4.0-4.5, precipitating the whey, removing the supernant from the precipitated whey, clarifying the supernant, adding a water, saline and phenol mixture to the clarified supernant to obtain the desired concentration, sterilizing the mixture, and placing the sterilized mixture into containers for subsequent storage and use.
Claim 2
Independent Claim
96 words
The method of preparing bovine colostrum for use in treating livestock comprising the following steps, collecting bovine colostrum milk, removing substantially all of the fat from the colostrum milk, removing the casein from the colostrum milk to obtain bovine colosteral whey, dializing the whey, adjusting the pH of the dialsate to 4.0-4.5, precipitating the whey, removing the supernant from the precipitated whey, clarifying the supernant, adding a water, saline and phenol mixture to the clarified supernant to obtain the desired concentration, sterilizing the mixture, and placing the sterilized mixture into containers for subsequent storage and use.
Claim 3
Dependent Claim
35 words
The method of claim 1 wherein said bovine colostrum milk is frozen after collection, said frozen milk then being partially thawed, said fat being removed by skimming off the fat from the partially thawed milk.
Claim 4
Dependent Claim
22 words
The method of claim 2 wherein substantially all of the remaining fat is removed after the partially frozen milk is completely thawed.
Claim 5
Dependent Claim
13 words
The method of claim 3 wherein said fat is removed by centrifugal separation.
Claim 6
Dependent Claim
72 words
The method of claim 1 wherein the casein is removed by: a. adding approximately 1.0-2.0 mg of CaCl 2 per liter of milk; b. adding approximately 0.5-1.5 tablets of rennin per liter of milk; c. mixing the mixture; d. heating the mixture to 20-80° C; e. mixing the heated mixture; f. allowing the heated mixture to stand until the casein precipitates from the mixture; and g. filtrating the casein from the mixture.
Claim 7
Dependent Claim
23 words
The method of claim 5 wherein the whey is dialized against tap water having a temperature of 40°-54° F for approximately 96-120 hours.
Claim 8
Dependent Claim
17 words
The method of claim 6 wherein the whey is precipitated by heating the dialsate to 35°-65° F.
Claim 9
Dependent Claim
19 words
The method of claim 7 wherein the supernant of the precipitated whey is removed from the mixture and centrifuged.
Claim 10
Dependent Claim
25 words
The method of claim 8 wherein water, saline and 0.3% Phenol mixture is added to make a final bovine IGG concentration of 100 mg %.
