Definitions

  • This invention relates to ruminant feedstuffs and to their production.
  • the rumen In the case of protein metabolism, it is known that at certain times during the period of growth and development, and subsequent lactation in the case of a high- yielding dairy cow, the rumen is not capable of producing sufficient microbial protein to meet the animal's full requirements for maximum growth or maximum production of milk. It is therefore desirable that a proportion of the animal's protein requirement be met by supplying a supplement containing protein which is not degraded in, and thus passes through, the rumen. This can result in an improvement in feed conversion efficiency, growth rate and production as compared with the use of an equal weight of degradable protein, which degradable protein does not bypass the rumen.
  • the free fat or free fatty acids can physically coat fibrous or cellulosic material in the rumen and thus prevent it from being broken down by the rumen micro-organisms. This can have an adverse effect on the total digestibility of the diet and result in a reduced yield of milk and/or butter fat. Further excess free fatty acids and especially some unsaturated fatty acids are toxic to certain micro-organisms in the rumen and this too can have an adverse effect on the total digestibility of the diet.
  • GB-PS 2113521 describes ruminant feedstuffs comprising animal or vegetable protein nutritional material dispersed in an edible, water-insoluble calcium or magnesium salt of a fatty acid, the said salt constituting 50 to 80% of the feedstuff.
  • the nutritional material is dispersed in the edible water-insoluble fatty acid salt or salts.
  • the fatty acid salt is insoluble, and thus it passes substantially unaltered through the rumen to the relatively acidic conditions of the abomasu and small intestine, where the salt is converted to the free acid and mineral ion which can then be utilised.
  • This feedstuff can be obtained by forming a dispersion of the protein material in an aqueous solution of a water-soluble salt of the fatty acid and then adding an aqueous solution of a compound comprising a calcium or magnesium cation which forms a water- insoluble salt with the fatty acid so that an edible water- insoluble fatty acid is precipitated on the dispersed animal or vegetable protein.
  • the animal or vegetable protein may be dispersed in the fatty acid salt while the latter is in the molten state and then the mixture is allowed to cool.
  • US-PS 4826694 describes a dry friable, easy-to- handle, ruminant feedstuff comprising edible water-insoluble calcium or magnesium salt of fatty acid, extractable triglycerides and edible calcium or magnesium oxide.
  • This feedstuff is produced by forming a mixture of basic oxide such as calcium oxide, fatty acid and triglycerides and water and allowing the oxide to react with the acid to form the water-insoluble salt.
  • a feedstuff containing up to 65% by weight of proteinaceous nutritional material.
  • the protein in the feedstuff of GB-PS 2113521 and any protein in the product of US-PS 4826694 is substantially in its native or unprocessed state and any protection of the protein within the rumen is provided by the presence of the water-insoluble fatty acid salt.
  • elevated temperatures occur in the production of these products, for example as a result of the exothermic formation of the fatty acid salt, the conditions are not such as to allow the rumen degradability of the protein material to be substantially affected. Accordingly these processes are not suitable for producing rumen-bypass protein.
  • a ruminant feedstuff which comprises, in admixture, one or more edible, water-insoluble calcium or magnesium salts of one or more saturated or unsaturated fatty acids, and animal or vegetable protein nutritional material, the protein nutritional material having been converted during formation of the fatty acid salt, e.g. by interacting fatty acid and calcium or magnesium compound, into a form which is substantially non-degradable in the rumen but which is digestible in the lower gut.
  • the animal or vegetable protein material contained within the feedstuff according to the present invention is of improved non-degradability and by-passes the rumen with substantially reduced loss of protein within the rumen compared to that shown by the animal/vegetable protein when in its native or unprocessed state.
  • the protein material in the feedstuff according to the present invention is digested in the lower gut with a high level of efficiency, for example not less than 60% and preferably better than 75% digestible.
  • substantially non-degradable in the rumen is to be understood that less than 50%, preferably less than 30%, of nitrogen in the feedstuff is lost from a sample of the feedstuff suspended in a bag, e.g. Dacron bag, in the rumen for 16 hours.
  • a bag e.g. Dacron bag
  • the feedstuff according to the present invention cannot be obtained by simple mixing.
  • the conditions of processing of the ingredients are important and must be such as to render the protein material substantially rumen non- degradable on the one hand but, on the other hand, must not be so severe as to render it also lower gut non-digestible.
  • excessive heat treatment can render proteins both rumen-non-degradable and lower gut non-digestible (Wilson PN and Strachan PJ, Undegradable protein and the protein requirement of dairy cows, Recent Advances in Animal Nutrition 1980, Butterworths) .
  • the processing conditions will of course vary according to the amount and type of protein material being processed.
  • the feedstuff according to the present invention usually is in particulate form and comprises a substantially homogenous mixture of the ingredients.
  • the proportions of the ingredients in the feedstuff can be adjusted to satisfy or meet the energy and protein requirements of the animals to be fed.
  • the feedstuff will contain at least 30% by weight protein material and up to 70% by weight calcium or magnesium fatty acid salt.
  • the feedstuff may contain 30 to 90% by weight, preferably 40 to 75%, alternatively 55 to 80% by weight, protein material and, respectively, 70 to 10%, 60 to 25% or 45 to 25% by weight fatty acid salt.
  • the feedstuff according to the present invention may contain other conventional ingredients, including further ingredients as described in GB-PS 2113521 and US-PS 4826694.
  • the present invention also provides a process for the production of ruminant feedstuff, which process comprises forming a substantially homogeneous mixture of animal or vegetable protein nutritional material, one or more fatty acids and a calcium or magnesium compound capable of forming an edible water-insoluble salt with the fatty acid(s) at elevated-temperature such that salt formation is initiated and maintaining the processing conditions until the protein material is rendered substantially rumen non-degradable but digestible in the lower gut, and then cooling the product.
  • This is a particularly convenient production process, in which the calcium or magnesium salt is formed, with the heat of reaction being employed to provide at least part of the conditions required for treatment of the protein material to render it rumen non-degradable.
  • the process according to the invention may be carried out batchwise using a reactor or, more conveniently, continuously e.g. using a reactor conveyor.
  • the process ingredients In order to initiate the salt formation, the process ingredients must be raised to elevated temperature.
  • the actual temperature will vary according to the particular fatty acid and calcium or magnesium compound to be reacted but generally a temperature of the order of 50 to 70°C may be sufficient.
  • ruminant feedstuff may be obtained by forming a substantially homogeneous mixture of animal or vegetable protein nutritional material, one or more fatty acids, suitably in liquid form, and a calcium or magnesium compound capable of forming an edible water-insoluble salt with the fatty acid(s) under the conditions employed, initiating reaction of the fatty acid(s) and calcium or magnesium compound, suitably by injecting steam into the substantially homogeneous mixture formed, maintaining the mixture at elevated temperature, e.g. 110 to 115°C, until the protein nutritional material is rendered substantially non- degradable in the rumen while remaining digestible in the lower gut, and then cooling the product, which may then if necessary be disintegrated to the desired particle size, and packed.

  • the animal or vegetable protein nutritional material used according to the present invention is preferably a good quality animal or vegetable protein.
  • Such nutritional materials are grass meal, lucerne meal, field beans, peas, lupin seed, coconut meal, cottonseed, groundnut, linseed, palm kernel, soya bean, sunflower seed, rape seed, fish meal, meat and bone meal, skimmed milk, whey protein, distillers' by-products, barley, maize, oats, rye, rice, gluten meal, locust bean, canola, feather meal, sorghum, safflower seed, single cell protein, and yeast, all of which are suitable for feeding to ruminants to improve the quality of their protein intake.
  • Such materials may be ground as necessary before inclusion in the feedstuffs according to the present invention.
  • references to seed, kernel and fruit nutritional materials include references to corresponding meals (which may be defatted) made therefrom, e.g. rapeseed and soya bean meals.
  • oleaginous protein material e.g. full fat seeds
  • the oil or fat contained therein may be converted, at least partly, into free fatty acids which, in turn, will react with the calcium or magnesium compound resulting in the presence of additional fatty acid salt in the feedstuff.
  • the fatty acids used in the invention are edible, saturated or unsaturated fatty acids suitably containing 14, 16, 18 and 20 carbon atoms per molecule, preferably myristic acid, palmitic acid, stearic acid, oleic acid, linoleic acid or linolenic acid. However higher and lower carbon content acids may also be used such as lauric and arachidic. It is normally preferred to use a naturally occurring mixture of such fatty acids derived for example from beef or mutton tallow, lard, palm oil, rapeseed oil, olive oil, soya bean oil or groundnut oil. Such materials are produced as by ⁇ products of edible oil refining.
  • Calcium oxide is the preferred basic oxide for use in the process according to the present invention but magnesium oxide may also be used.

Abstract

Un aliment pour ruminants comprend un mélange d'un ou plusieurs sels d'acides gras de calcium ou de magnésium non hydrosolubles comestibles et d'une substance nutritive à base de protéines animales ou végétales, substance transformée pendant la formation du sel d'acide gras en élément non dégradable en pratique dans la panse mais digestible dans l'intestin. On peut obtenir cet aliment en formant un mélange homogène en pratique de cette substance nutritive à base de protéines animales ou végétales, d'un ou plusieurs acides gras sous une forme liquide appropriée et d'un composé de calcium ou de magnésium capable de former un sel comestible non hydrosoluble avec l'acide gras dans les conditions d'utilisation. On enclenche la réaction du ou des acides gras avec le composé de calcium ou de magnésium de manière opportune en élevant la température des ingrédients, par exemple en injectant de la vapeur dans le mélange homogène ainsi formé, qu'on maintient à une température élevée, 110 à 115 °C par exemple, puis on refroidit le produit. Ce procédé comporte aussi l'avantage de détruire en pratique d'éventuelles mycotoxines présentes dans la substance nutritive grâce à l'action combinée des températures élevées et des acides et des bases gras, l'oxyde de calcium par exemple, utilisés de préférence.
