ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of The Invention
Applicant's invention relates to a feedstock for herbivores and the method of using the feedstock to improve digestive efficiency and control harmful and toxic plants. Specifically, this invention relates to inexpensive additives which can be added to feedstock and fed to ruminants, e.g. goats, deer, and cattle, to absorb or adsorb defensive organic plant chemical compounds.
2. Background Information
Members of the family of woody plant weeds commonly called cedars or junipers have spread over a substantial part of the North American continent. These weeds deprive the soil of nutrients that would be available to other plants, such as forbs and grasses, on which domesticated animals as well as wild animals, such as deer, feed. These weeds are also a major source of allergens caused in the Southwest part of the United States. One cause for the spreading of these weeds is that herbivores, particularly ruminants, whether domesticated or wild, do not adequately feed on them. The animals are repelled from feeding on junipers because of their defensive organic constituents. For example, female goats that feed on most plants and trees do not consume substantial quantities of junipers because of their defensive chemicals. It is hypothesized that the chemicals may, for example, upset the delicate balance of microorganisms in the herbivore's stomach. It has also been hypothesized that some examples of the defensive compounds are terpenes. There are other mechanisms by which defensive chemicals may act.
Examples of junipers growing in the Southwest United States containing defensive organic compounds are: Rocky Mountain Juniper; Western Juniper; One Seed Juniper; Utah Juniper; California Juniper; Alligator Juniper; Pinchot Juniper; A she Juniper; Weeping Juniper; and Eastern Red Cedar. Similar chemical defense compounds against grazing animals are found also in other plants, such as creosote-bush, larkspur, western bitterweed, woolly paperflower, mustards, spurges, agarito, perennial snakeweed, and oaks. The oil or solvent soluble chemical constituents in other plants which repel, sicken or kill grazing animals should also be absorbed by or be adsorbed onto the polymers. Examples of these compounds are terpenes, diterpenoid alkaloids, organic thiocyanates, sesquiterpenoid lactones, tesinoids, resins, tannins, and creosotes. It is recognized that activated charcoal will also absorb some of these compounds and provide relief from their toxic symptoms.
It is well known that oil or solvent soluble organic compounds, including mono, di, tri and tetraterpenes, and their derivatives can be absorbed or adsorbed by polymers. The rate of absorption is determined usually by the surface area contacting the oil and by the rate of permeation of the oil into the polymer. The available surface area can be readily increased by shredding the polymer. This increases the rate of uptake, whether by absorption or by adsorption bringing it to within a period comparable to or shorter than the dwelling period of the plant in the rumen and remainder of the digestive system. A specific family of polymers in which permeation rates and therefore absorption rates can be high is the family of elastomers, which are rubbery materials. A source of particularly inexpensive elastomeric materials is the used tire, for example the used automotive tire. Tires may comprise polymers or copolymers of butadiene or isoprene. Such polymers or copolymers may include polyisoprene, polybutadiene, and/or ABS rubber. ABS rubber is a copolymer of acrylonitrile, butadiene, and styrene. Applicant is unaware of any information in the prior art which suggests that these polymers can be combined into a feedstock, as does the present invention. Nor is applicant aware of any prior art that indicates that these polymers can be fed to herbivores to allow them to improve their digestive process and to eat harmful and toxic plants which contain oil or solvent soluble organic compounds, as does the present invention.
Furthermore, it is known in the prior art that ruminants can be fed water insoluble water swellable polymers to absorb acid conditions in the rumen resulting from the ingestion of prepared foods, e.g. silage, but not open pasture. U.S. Pat. No. 5,004,603. However, applicant is unaware of any prior art that suggests that a nonwater-swellable as well as nondigestable polymer, such as in the present invention, can be used to absorb harmful plant chemicals in the gut of the herbivore.
Presently, there do not appear to be any polymer compositions available on the market that act as feedstocks for herbivores to absorb oil or organic solvent soluble chemicals from plants, for instance to aid ruminants in eating cedar and juniper. The present feedstock can be fed to an herbivore so as to absorb or adsorb the harmful chemicals in the herbivore's digestive system thereby allowing the herbivore to digest its food more efficiently and eat more of the harmful, and potentially toxic, plant. This feedstock can therefore also be used as a means to control harmful and toxic plants.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a feedstock which contains organic polymers which absorb or adsorb harmful plant oil or solvent soluble organic compounds in the digestive system of an herbivore.
It is still another object of the present invention to provide a feedstock which contains organic polymers which absorb or adsorb harmful plant oil or organic solvent soluble organic compounds in the rumen of a ruminant.
It is another object of the invention to absorb in the digestive tract of herbivore volatile oils and other organic oil or solvent soluble chemicals which interfere with the digestive process thereby improving digestive efficiency generally.
It is another object of the present invention to provide a feedstock for use in controlling harmful and toxic plants.
It is another object of the present invention to provide a method of using a feedstock to control harmful and toxic plants.
It is an object of the present invention to provide a feedstock to aid herbivores in eating harmful and toxic plants.
It is another object of the present invention to provide a feedstock which contains elastomers.
It is yet another object of the present invention to provide a feedstock which contains organic polymers which are excreted intact by the herbivore.
It is a further object of the present invention to provide a feedstock which contains a polymer or copolymer of butadiene or isoprene.
It is another object of the present invention to provide a feedstock which contains polyisoprene, polybutadiene, and/or ABS rubber.
It is still another object of the present invention to provide a feedstock for use in absorbing or adsorbing harmful plant oil or solvent soluble organic compounds in the digestive system of an herbivore.
It is a further object of the present invention to provide a feedstock for use in absorbing or adsorbing plant terpenes, thiocyanates, terpine derivatives, resins, resinoids, tannins, diterpenoid alkaloids, sesquiterpenoid lactones, and creosotes.
It is still a further object of the present invention to provide a feedstock which contains organic polymer absorptive or adsorptive materials which absorb terpenes, organic thiocyanates, plant resins, resinoids, plant tannins, diterpenoid alkaloids, sesquiterpenoid lactones, plant creosotes, and large aldehydes and ketones.
It is yet another object of the present invention to provide a feedstock which can be used to control allergens released from harmful and toxic plants.
It is another object of the present invention to provide a feedstock which can be fed to herbivores to aid them in eating more classes of indigenous plants thereby controlling pasture overgrazing problems.
It is another object of the invention to aid the digestion of herbaceous materials originating from both prepared feeds and open pasture.
It is still another object of the present invention to provide a feedstock which can be fed to a ruminant with
