Abstract

The composition has a dry weight of 750 to 850 g/l, it assays 13.5-16.5% of urea nitrogen and 5.5-7.5% (by weight) of phosphorus. In a preferred form, it contains, in addition, certain proportions of ammonia nitrogen, sulphur, zinc, manganese, copper, iodine and cobalt. The composition is prepared by mixing, in the weight ratios corresponding to the above levels, urea phosphate and urea and by dissolving them in water; for the preferred composition, ammonium sulphate and the sulphates of the trace elements mentioned are added. The composition can be advantageously used with cellulosic vegetables low in nitrogen and phosphorus.

Description

The present invention relates to an aqueous liquid composition for the enrichment of cellulose vegetable matter for animal feeding.

,.- ' The complementing of vegetable residues with compounds such as mineral salts, vitamins, hormones, molasses or *. f residuary liquor from sugar refining has been the subject of many papers. •j . For example, Russian Patent No. 268,884 deals with ’ the enrichment of beet pulp with a nutritive supplement • 10 consisting of orthophosphoric acid, urea and sodium . sulphate in order to reduce loss through storage. German ΐ Patent No. 1,930,609 describes a food with good storage i · properties prepared by the incorporation of solid crystall > lised mineral salts into cossettes11 of beet pulp.

The attractive, nutritional properties of mixtures s . . > . of urea and urea phosphate are also known and in our j French Patent No. 2,273,482 and our French Patent of Addition No.· 2309158, we describe a method of pre;-.. . paring nutritive compounds for animal feeding based on 20 a mixture,- in fixed proportions, of dry vegetable residues = ’ · with a mixture of melted urea and urea phosphate.

However, these various methods do not yield entirely t satisfactory results. Thus, for example, the addition of - ; mixtures of crystallised products or of melted salts to the j 25 cellulosic'Vegetable matter can be difficult to carry out. ( ί Furthermore, the resultant foods can often be deficient, μ :i if not in nitrogenous substances andphosphorus, at least . . in sulphur, trace elements or vitamins, and this deficiency 5 · ' : has to be made good by the introduction of supplementary j 'I - 30 additives. - 2 45616 According to the present invention there is provided a liquid aqueous composition for the enrichment of cellulose vegetable matter of very poor food value for animal feeding, the composition having a dry material content of 750 to S50 g/1 and comprising 13.5 to 16.5% by weight of ureal nitrogen, 0. to 3.5% ammoniacal nitrogen s 5.5 to 7.5% phosphorus, 0 to 4% sulphur, 0 to 0.44% zinc, 0 to 0.15% manganese, 0 to ppm by weight copper, 0 to 8 ppm iodine and 0 to 0.6 ppm cobalt.

.The composition of the present invention may include all the basic elements needed for a good food, ureal nitrogen, ammoniacal nitrogen, phosphorus, sulphur, as well as the necessary trace elements: zinc, manganese, copper) iodine, cobalt and the vitamins A, Dj, E. When it is desired to introduce vitamins into the cctnpositions of the invention, generally the following doses are used, Vitamin A: to 100,000 international units (I.U.) vitamin 0 to 20,000 I.U., vitamin E:0 to 20 I.U, each range being per kg of solution. The specific gravity of the composition of the invention is 1.25 to 1.30, its Brookfield viscosity at 20°0 is 9 to 11 centipoises and its crystallisation point is always below -6°C.

Because of its high dry material content the composition of the invention can be used without difficultyin existing dehydration plant and requires no further, or complementary drying of the dry vegetable base which has been enriched in this way. It is perfectly clear and fluid, can be stored in tanks which are not agitated, and can be sprayed without difficulty, and without blocking, through the finest jets.

•· The present composition is particularly suitable for the enrichment of beet pulps but it can be used with advantage in general with all cellulose vegetable matter poor -in nitrogen and in phosphorus, such as ground . fodder, straw whether treated with soda or not, maize cobs, brans, chaff, fragments and bran from rice, ground draff from breweries, beetroot cossettes, potato pulp, fruit pulp, especially of citrus fruits,' sugar cane bagasses, ground nut shells and cacao husks, banana flour, and flour from different kinds of vegetable matter.

The composition for enriching cellulose vegetable matter according to the invention can be prepared starting , from metallic salts by any suitable method, but the • simplest method consists in mixing appropriate amounts of the starting crystallised salts, then dissolving them in the required amounts of water which are raised progressively to a temperature of 50 to 60°C. Utilisation of all the salts which, in suitable proportions, make it possible to obtain the desired content of chemical elements is possible, but the use, apart from urea phosphate and urea, of ammonium sulphate and sulphates of the various other introduced metals is the most practical and most economic method of preparing the compounds according to the invention.

From the raw materials which are available it may . be of advantage to use, instead of urea phosphate, phosphoric - 4 4S361G acid, And the appropriate supplement of urea. In such a case the' urea supplement is mixed in the crystallised form with the other salts and the phosphoric acid is previously’ added to the amount of water needed to give the desired content of dry material.

With the liquid compositions of the invention it is possible to obtain complete foods for ruminants which are of exceptional value in that they give proportions between the different components which are especially well adapted to complementing·the vegetable residues and are particularly well suited to the feeding requirements of the ruminants.

The present compositions may be utilised for the enrichment of dehydrated vegetable matter for the manufacture on an industrial basis of liquid animal feeds, or directly, on the farm, for spraying animal foodstuffs.

A vegetable dehydration works constitutes a particularly advantageous site for the incorporation 2o of the compositions of the invention in fodder, especially in beet pulps and dehydrated maize, with which it is possible to obtain complete foods which are perfectly adapted to fattening bull calves, the raising of heifers, and as a basic ration for dairy cattle. A tank, a pump, a flow meter, plastic hose and a spray nozzle are enough to ensure good distribution of the product.

The compositions of the present invention can be used by manufacturers of cattle feeding stuffs to make up economically and practically a liquid feed capable of 30 meeting the requirements of cattle breeders. Thus the ccrnpositicns of the present invention can be added to cellulose vegetable matter such as beet pulp, citrus pulp,-sugar cane bagasse, - 5 4 5616 ί 'ft1 .-'ϊ • i -s 5 1 straw, fodder or any fibrous matter. For ' example a food with 40/50% protein equivalent can be obtained by mixing 300 to 400 litres of the composition of the present invention with 400 litres of molasses and 250 litres of a pickling brine, a solution with 20% sodium chloride and 5%·' calcium chloride. A liquid composition of · this type may equally well be sprinkled, and incorporated • in a feeder of - the ball - type or of the licking wheel type. lo . The following Examples illustrate the invention.

- Example 1 The available material is a dehydrated beet pulp with the following composition: - dry material ............ 87.4% - mineral materials ......- . . . . . 5 >1 % of the dry material ' • 1 '1 i j.

Since dissolution is strongly endothermic the paste is kept at ambient temperature until dissolution is complete by means of an external source of heat. Once dissolution has ended the temperature is raised to 60°C, kept there for about ten minutes, and then the mixture is allowed to cool.

In this way a metric ton of a clear, fluid liquor is obtained having a specific gravity of 1.282, Brookfield viscosity at 20°C of 10, a titration value of 6.43% phosphorus and 17-2354 nitrogen in all.

The liquor, prepared as just described, is sprayed over the beet pulp before it is dehydrated, at the-rate of 35 litres of liquor per metric ton of pulp dry matter.

The pulp, thus complemented, dehydrated and conditioned in small rolls with a diameter of 7 to 10 mm, has the following compositions: - dry material ........... 87.7 % - mineral material ......... 7.4 % of the dry material - total nitrogenous material ....... 14. 8% - cellulose material........ 20. 2% - fodder units ..... 0.79% - phosphorus ............ 0.39% - calcium .............. 0.86% - sodium . . . . ..........0.11% ' ς. 45616 - sulphur .,..,........., 0.37% of the dry material - to .....113.2 ppm of dry . . material - Zn ...............89.' 4ppm 11 _ Cu ...............14.5 This complemented beet pulp was used to feed a batch of 20 Salers bull calves in comparison with another batch of . bull.calves who were fed an uncomplemented pulp, i.e. a • pulp having no addition of liquor in accordance with the present invention.
