Abstract
This invention relates to aqueous compositions suitable for ensiling substrates said composition comprising formic acid and octanoic acid. The composition may contain in addition other components such as propionic acid and ammonia to improve ease of handling. The feature of the invention is that octanoic acid, which when used alone, has no ensiling or fermentation activity, has enhanced ensiling activity when used in conjunction with formic acid and thus increases nutritionally desirable sugars in the ensiled product.
Description
COMMONWEALTH OF AUSTRALIA PATENTS ACT 1952 COMPLETE SPECIFICATI 5 7 FOR OFFICE USE Short Title: Int. Cl: Application Number: Lodged: Complete Specification-Lodged: Accepted: Lapsed: Published: Priority: Related Art: TO BE COMPLETED BY APPLICANT Name of Applicant: BP CHEMCIALS LIMITED Address of Applicant: Belgrave House, 76 Buckingham Palace Road, London SW1W OSU, ENGLAND Actual Inventor: David Andrew JACKSON; Edward MCGEE and David Andrew PARKER Address for Service: GRIFFITH HACK CO 71 YORK STREET SYDNEY NSW 2000 Complete Specification for the invention entitled: ENSILING COMPOSITION The following statement is a full description of this invention, including the best method of performing it known to us:- 04185-KY PJW/SMcL 2658A/SMcL Case 7312/7417(2) lA- ENSILING COMPOSITION The present invention relates to a composition for use in silage preparation which enables the enhancement of residual sugars during fermentation of silage.
0o Formic acid is well known to be an excellent silage additive.
0 O 5 The acid, usually at about 80%w/w concentration in aqueous solution, is usually applied on the substrate to be ensiled at the rate of about 2-4 litres per ton. At these levels lactic acid fermentation 00 o o o 0 occurs. In order to restrict the fermentation process and to 0 .0 enhance the residual sugar content of the ensiled substrate e.g.
grass, it is necessary to increase the application rate of formic acid (85%w/w) to about 6 litres per ton.
However, increasing formic acid in silage not only makes the 0o 0 silage less palatable to the animals but inevitably increases acidity of the silage thereby causing corrosion problems during 0o o storage etc. Moreover, formic acid has relat’vely low antimicrobial activity and hitherto this has been mitigated by the use of various quantities of sterilants such as e.g. formaldehyde.
It has now been found unexpectedly that a higher carboxylic o acid when used together with formic acid in appropriate proportions o 20 can mitigage these effects.
Accordingly, the present invention relates to an aqueous composition suitable for use as an ensiling agent comprising a combination of formic acid and octanoic acid.
The relative proportions of formic acid and octanoic acid in the composition are suitably such that for every 100% w/w of -n
IA-
I
2 aqueous solution of formic acid (containing 85% w/w formic acid) there is present suitably from 0.5-10% w/w, preferably from 2-8% w/w of octanoic acid.
The composition is most suitable for ensiling substrates and is preferably applied to the substrate in an amount ranging from 0.35 to 0.9% w/w, most preferably from 0.4-0.7% w/w of the substrate.
Preferably, the aqueous composition conzains 10-50% w/w of water.
The compositions of the present invention may contain in addition other components including propionic acid and ammonia depending upon the activity desired. For instance in a formulation containing both these additional components, formic acid and octanoic acid, the ratio of propionic acid to octanoic acid is suitably at least 2 1 w/w, preferably from 3 1 to 5 1 w/w; and the molar ratio of formic acid to ammonia in said composition suitably is at least 4 1, preferably from 4 1 to 8 1, typically 6 1.
SThus a typical composition of this type may contain 75.7% w/w of an aqueous solution of formic acid (corresponding to 64.345%w/w actual formic acid), 10.0% w/w propionic acid, 2.0% w/w octanoic S 20 acid and 12.3% w/w aqueous ammonia. (corresponding to 4.06% w/w actual ammonia).
The composition may be applied to the substrate either by direct mixing of the harvested substrate with the ensiling formulation or by impregnating a particulate and porous carrier material such as pumice, vermiculite, perlite dried beet pulp or dried citrus pulp with the formulation and then uniformly distributing the impregnated carrier into the substrate to be ensiled.
Thus, according to a further embodiment the present invention is a process for ensiling substrates as hereinafter defined, said substrate being treated with an aqueous composition by mixing said composition comprising a mixture of formic acid and octanoic acid thoroughly with the substrate to be ensiled.
By the term «substrate» is meant here and throughout the specification grass, agricultrual crops and whole plant materials 2 3 used in preparing animal feedstuffs such as grass, lucerne, alpha alpha, barley, wheat, oats, rye, maize, rice, hay, silage, tick beans, soya beans, sunflower seed, rape seed, groundnuts.
A feature of the invention is the synergistic effect observed by using a combination of these acids whereby the C 8 acid not only aids inhibition of the rapid fermentation induced by relatively low levels of formic acid so as to reduce levels of lactic acid formed and enhance residual sugars in the ensiled substrate but also confers a preservative antimicrobial effect on the substrate treated.
Moreover, the level of formic acid addition can be reduced in spite of the C 8 acid which, when used alone, has little or no known ensiling or fermentation activity.
The present invention is further illustrated with reference to 15 the following example and accompanying graph.
°Example 1 o ?The experiments reported below were designed to compare he o o effect of formic acid (85%w/w aqueous solution) applied at 1,3,5 o o and 7 litres/t, alone and (ii) as a blend thereof with octanoic acid on the biochemicals changes occurring during the ensilage of lucerne (Medicago sativa).
The residual sugars (water soluble carbohydrates) found in the o° o silage after 100 days peaked at the application rate of 5 litres/t.
o< At these levels fermentation of the silage was clearly restricted and the inclusion of octanoic acid increased the efficacy of S" the additive. This is graphically shown in Figure 1.
Examples 3 and 4 (Laboratory Scale): During the natural fermentation process of ensilage, the desirable sugars found in grass are converted to undesirable lactic 0o 0 30 acid by the epiphytic microflora. This results in the production of 0 00 a forage that is deficient in the desirable sugars and therefore the efficiency of utilisation by the animal is reduced. The formulations of the present invention were developed specifically to suppress this natural fermentation process and therefore enable these feedstuffs to retain many of the nutritional advantages of 3- I' I -4fresh grass feed.
The following Examples 2, 3 and 4 demonstrate this effect. In these Examples the ensiling formulation used contained: Aqueous formic acid 75.7%w/w (64.345%w/w actual formic acid) Propionic acid 10.0%w/w Octanoic acid Aqueous ammonia 12.3%w/w (4.06%w/w actual ammonia).
Example 2 (Farm Trial): The st-.dy was carried out on a dairy farm.
A total of 1300 tonnes of grass was ensiled on 3rd July, 1989 with approximately 500 tonnes treated with the formulations specified above at 6 litres/tonne level by thoroughly mixing the formulation with the chopped grass as it was being harvested. The remainder was left untreated. In both cases the grass was stored 15 under substantially anaerobic conditions for 50 days.
Thereafter the ensiled samples were analysed for standard nutritional parameters using the techniques described in "The Analysis of Agricultural Materials", Ministry of Agriculture Food and Fisheries, RB 427, 2nd Edition, published in 1981 by Her Majesty's Stationery Office, London. The appropriate pages relevant for the specific analyses are indicated, where applicable, in the Tables below: Results q 0 ae o 4 i 4 0 S440 40 4 0a *ss 4 t t t 1 1 s a 4 4 1 400 I 04
