RUMEN BYPASS COMPOSITION OF BIOLOGICALLY ACTIVE

INGREDIENTS

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 US3959493 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.

US5093128 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 US patent 5807594 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 C8H1705NRR', 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.

US4808412 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.

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 Lutein granules in water was done by adding Lutein rumen bypass formulation at concentration lmg/ml in water at continuous stiring at 50 RPM. Sample was collected at regular intervals (0, 1, 2, 3, 4, 5, 6, 7, 8 hrs) and analysed for Lutein 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 (Figure (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.
