Title: Rumen bypass composition of biologically active ingredients

Description:
FIELD OF INVENTION 
     The present invention discloses rumen bypass and thermally stable composition containing rumen bypass coating/encapsulation matrix and biologically active substances. More particularly, the present invention discloses rumen stable/rumen bypass coating or encapsulation matrix for biologically active substances. 
     BACKGROUND AND PRIOR ART OF THE INVENTION 
     Rumen fermentation reduces the nutritive value of carbohydrates and proteins while destroying unsaturated lipids by hydrogenation and also degrade unprotected biologically active agents that are delivered orally to ruminants substantially by bacteria which contain fermentation enzymes. 
     In ruminant animals, such as cattle or sheep, the direct oral administration of biologically active substances, such as amino acids and vitamins, causes most of the substances to be decomposed in the rumen due to bacteria which contain fermentation enzymes; thus they are not effectively utilized/absorbed. Therefore, it is important to bypass the biologically active substances through the rumen without decomposition to allow the biologically active substances to be effectively digested and absorbed in the subsequent digestive tract, so as to improve the health and productivity of ruminants. For example, the bacteria in the rumen of a cow easily degrade or metabolize amino acids, like lysine and methionine into its by products and therefore, when the biomass reaches the intestine there are no amino acids remaining for the absorption by the animals. 
     The rumen is the largest of the four digestive chambers of ruminants and the microorganisms present in the rumen degrade the diet by fermentation process over a period of time from about 10 to 30 hours or longer. Most of the ingested protein material breaks down in the rumen to soluble peptides and amino acids that are used as nutrients by the rumen microorganisms. The rumen contents are passed into the subsequent digestive chambers along with the microorganisms. Once the contents dump into the abomasum and intestine, the microbial mass is digested, providing protein and amino acids to the ruminant. Therefore, the nutrients and medicaments shall be designed for use with ruminants must be protected against microbial action and the effects of pH, so that the active agent can remain bioavailable at the absorption site, thereby enabling the ruminant to increase its productivity such as increased quantity and improved quality of milk, meat etc. 
     There is ample literature available on methodologies that are designed to protect biological active ingredients such as amino acids, vitamins and minerals from ruminal degradation including heat and chemical treatment, encapsulation and coating, etc. 
     The earliest literature on these methodologies include U.S. Pat. No. 3,959,493 which discloses a rumen bypass system that uses aliphatic fatty acids having at least 14 carbon atoms, applied as a coating to the nutrient because the said fatty acids are resistant to rumen degradation. The active agents then are delivered to the abomasum and/or intestine where the fatty acids are reduced in that post-ruminal environment. 
     U.S. Pat. No. 5,093,128 describes a beadlet nutrient coating which includes fats and calcium based products. Coated ruminant nutrients have the disadvantage of cracking or abrading either in handling or in being masticated by the animal. Yet another U.S. Pat. No. 5,807,594 attempted to improve weight gain and feed efficiency in a ruminant by encapsulating a choline chloride composition in a rumen-protected carrier. The suitable encapsulating or coating materials for use in this invention include among others: hydrogenated oils, mono- and di-glycerides, waxes, and seed fats. All these encapsulation materials are thermally unstable. 
     US20020127259 suggests providing a composition comprising (i) a modified lecithin having the formula C8H17O5NRR′, wherein R and R′ are fatty acids having the formula CH3(CH2)nCOO, wherein n is between 4 and 22; and (ii) an active agent wherein said lecithin is present in an amount effective to protect said active agent from environmental oxidation. 
     As is evident from the foregoing, it has been proposed in the literature to coat ruminant animal feed additives containing biologically active substances with protective substances, such as higher melting point fatty acids, hardened animal oils and hardened vegetable oils. However, particles coated with these fats and oils are not only stable in the rumen, but also in the abomasum and subsequent digestive tract making the biologically active substances difficult to be released in the abomasum and subsequent digestive tract. The problems associated with these coating methods are costly, stability and suitability in mixing with feed, as they are sticky. They are also thermally unstable. 
     U.S. Pat. No. 4,808,412 reports a post-rumen effective composition for oral administration to ruminants containing a bioactive substance molecularly dispersed with a basic polymer. 
     In the light of the foregoing, there remains a need in the art to provide a thermally stable, rumen stable/rumen by pass coating or matrix for the delivery of biologically active substances, which is simple, cost effective, suitable, nonsticky, nonhygroscopic and delivers the active substance by bypassing the rumen.

     Process of Manufacturing Slow Release EPA and DHA Formulation
     1. Adding EPA and DHA granules to the coating equipment followed by starting the machine;   2. Slowly adding/spraying the preheated Palm fatty acid distillate to the contents of step (1);   3. Mixing well for uniform distribution of the contents of step (2);   4. Adding/spraying calcium hydroxide while mixing;   5. Mixing well to get the free flowing coated granules;   6. Sieving to remove excess calcium hydroxide;   7. Filling into different HDPE containers or into suitable packaging material for next coating.   

     Note: Rice bran wax can be used instead of Palm Fatty acid distillate

     Process for Manufacture of Multicoated Methionine Rumen Bypass Formulation:
     1. adding required amount of methionine granule to a cleaned coating equipment/planetary mixer;   2. Optionally, heating the contents of step (1);   3. Adding the preheated palm stearin/fatty acid into the contents of step (2);   4. Optionally heating the contents of step (3);   5. Mixing well for uniform distribution of the contents of step (4);   6. Adding calcium hydroxide while mixing;   7. Mixing well to get the free flowing dry granules coated with coating material embedding methionine;   8. Repeating step (1) to (7) for five times to get Methionine Rumen bypass multicoated granular product.   

     Testing for Stability of Granules: 
     The granules are expected to be stable without releasing the active ingredient for 8 hrs (retaining time of the feed in Rumen). Stability of methionine granules in water (considering the pH of rumen, which is 6.5 to 7) was done by adding methionine rumen bypass formulation at concentration 1 mg/ml in water at continuous stirring at 50 RPM. Sample was collected at regular intervals (0, 1, 2, 3, 4, 5, 6, 7, 8 hrs) and analysed for methionine content. No release of active ingredient observed upto 8 hours.

     Testing for Stability of Granules: 
     The granules are expected to be stable without releasing the active ingredient for 8 hrs (retaining time of the feed in Rumen). Stability of Sodium Butyrate granules in water was done by adding Sodium Butyrate rumen bypass formulation at concentration 1 mg/ml in water at continuous stirring at 50 RPM. Sample was collected at regular intervals (0, 1, 2, 3, 4, 5, 6, 7, 8 hrs) and analysed for Sodium Butyrate content. No release of active ingredient observed upto 8 hours. This indicates that, the product will be stable in rumen for 8 hrs.

     Testing for Stability of Granules: 
     The granules are expected to be stable without releasing the active ingredient for 8 hrs (retaining time of the feed in Rumen). Stability of Vitamin B12 granules in water was done by adding Vitamin B12 rumen bypass formulation at concentration 1 mg/ml in water at continuous stirring at 50 RPM. Sample was collected at regular intervals (0, 1, 2, 3, 4, 5, 6, 7, 8 hrs) and analysed for Vitamin B12 content. No release of active ingredient observed upto 8 hours. This indicates that, the product will be stable in rumen for 8 hrs.

Stability of Calcium granules in water was done by adding Calcium rumen bypass formulation at concentration 1 mg/ml in water at continuous stirring at 50 RPM. Sample was collected at regular intervals (0, 1, 2, 3, 4, 5, 6, 7, 8 hrs) and analysed for Calcium content. No release of active ingredient observed upto 8 hours. This indicates that, the product will be stable in rumen for 8 hrs.

     Testing for Stability of Granules: 
     The granules are expected to be stable without releasing the active ingredient for 8 hrs (retaining time of the feed in Rumen). Stability of Blend of organic acids granules in water was done by adding Blend of organic acids rumen bypass formulation at concentration 1 mg/ml in water at continuous stirring at 50 RPM. Sample was collected at regular intervals (0, 1, 2, 3, 4, 5, 6, 7, 8 hrs) and analysed for each organic acids content. No release of active ingredient observed upto 8 hours. This indicates that, the product will be stable in rumen for 8 hrs.

     Testing for Stability of Granules: 
     The granules are expected to be stable without releasing the active ingredient for 8 hrs (retaining time of the feed in Rumen). Stability of Choline/Protein granules in water was done by adding Choline/Protein rumen bypass formulation at concentration 1 mg/ml in water at continuous stirring at 50 RPM. Sample was collected at regular intervals (0, 1, 2, 3, 4, 5, 6, 7, 8 hrs) and analysed for Choline/Protein content. No release of active ingredient observed upto 8 hours. This indicates that, the product will be stable in rumen for 8 hrs.

     Thermostability of the Vitamin Formulation: 
     The thermostability of coated product from the present invention was tested in comparison to currently available product in the market ( FIG. 1 ). Known amount of products were taken in a separate glass container and boiling water was added to both the products. The results shows that, the product from present invention was stable and the currently available product is not. Thermostability enables the product to be used in pelletization of the feed, where the feed will be passed through extruder with high temperature (70 to 90° C.) and steam. The ubstable products will release the active ingredients during pelletization and hence not suitable.
