Definitions
- the present invention relates to a process for obtaining ruminant nutritional product containing carboxylic acids in the form of encapsulated microparticles for nutrition of ruminal microorganisms, as well as methods of providing them. More specifically, it comprises the isobutyric, isovaleric, valeric and 2-methylbutyric carboxylic acids, whether or not combined, their respective salts, intermediates, analogs, isomers, similar, precursors or derivatives, encapsulated in microparticle form.
- the present invention also relates to encapsulated microparticle-containing compositions of said carboxylic acids and methods of use obtained by said process.
- a diet that alters microbial protein production directly affects the quantity and quality of protein that reaches the small intestine, and thus of targeted products such as meat and milk.
- it has been an objective in ruminant nutrition to maximize the flow of microbial protein to the small intestine, thus increasing the productive efficiency, since besides having an excellent nutritional profile for the animal, it is undoubtedly the most protein source. for any production system.
- Most current ruminant nutrition additives belong to the class of antimicrobials, whose purpose is to "forcefully select" ruminal microorganisms, weakening or eliminating undesirable ones.
- additives which, even if intended for ruminants, target the animals' small intestines and thus rumen escape, or bypass, without fermentation.
- Formulations containing organic acids have gained ground in the world animal nutrition market as an important alternative to the use of additives.
- Isobutyric, isovaleric, and 2-methylbutyric carboxylic acids also known as branched chain volatile fatty acids, or isoacids, and valeric acid, are essential nutrients in ruminant nutrition.
- branched chain volatile fatty acids or isoacids, and valeric acid.
- cellulolytic bacteria These bacteria have their own requirement for essential nutrients, which, in addition to isoacids, also require ammonia (NH 3 ), B-complex vitamins and carbon dioxide (CO2).
- US 4,376,790 comprised a mixture of the ammonium isobutyrate, valerate, isovalerate and 2-methylbutyrate salts as a feed supplement for ruminants. Its efficacy has been scientifically proven through several studies, already known in the state of the art, showing perspectives of its potential use as a nutritional additive. However, the fact that the product was marketed in liquid form, coupled with issues of certain variability in the results, as well as possible rejection by the animals due to the strong odor, caused difficulties in the success of marketing. Such problems led to the application of new patent.
- WO 84/00669 comprised a composition of product mixtures of the reaction of nitrogen sources with isobutyraldehyde, isovaleraldehyde, valeraldehyde and 2-methylbutyraldehyde aldehydes as a feed compound for ruminants.
- the new formulation has advantages over the art because it apparently has a reduced odor and solid form presentation.
- aldehydes are known to have irritating odors and are practically insoluble. Probably for these reasons, the new formulation was not successful in the market either.
- EP 0 233 819 B1 comprised formulations in pelleted form containing a mixture of isobutyric, 2-methylbutyric, valeric and isovaleric acid calcium salts, with the addition of animal fat, tallow, or coconut oil, described to suppress the dust caused by calcium salts and facilitate the formation of pellets.
- animal fat, tallow, or coconut oil described to suppress the dust caused by calcium salts and facilitate the formation of pellets.
- the incorporation of oil or fat into the product, together with calcium salts has made the product very poorly degradable in the rumen, or bypass.
- the alleged improvements in art did not, in fact, achieve the proposed goal of benefiting the rumen of animals.
- Efficiency in ruminant production is achieved through better utilization and utilization of ingested fiber, for example from pasture and other feed as by-products, crop residues, among others, so that these animals are able to exploit their true ecological niche in the most economical way, offering them the best conditions to optimize their production by transforming the ideal food, fiber, into the perfect nutrient, microbial protein, which only a ruminant can produce.
- the process of encapsulating substances in animal nutrition has been growing day by day.
- the use of this process and its methods aim to protect the external environmental and / or internal digestive degradations of the active ingredients.
- ruminant animals have many particularities regarding the digestion of the food they eat, due to rumen-related characteristics, a complex environment compartment and dependent on the interaction between host and microorganisms, which live in perfect symbiosis.
- the encapsulation process applied to ruminant nutrition cannot simply be seen as a protection against ruminal degradation when the focus is on the rumen, and meeting the requirements of its microorganisms is a prime prerequisite.
- microparticle encapsulation process is defined herein as the inclusion or distribution of small particles containing said carboxylic acids in solid or semi-solid forms, or liquid droplets, in normally polymeric material.
- the resulting microencapsulate containing the active ingredients may further receive a coating, coating or film layer which allows the formation of a physical barrier between the external medium and the active ingredients, effectively reducing or even eliminating the pungent odor of carboxylic acids, and At the same time, it is capable of undoing under specific stimulus, releasing the active component at the ideal place and moment, ie, in the rumen and in sync with fiber degradation.
