Definitions

  • This invention relates to techniques for improving the efficiency of feed conversio growth and yield of meat from ruminant livestock.
  • US Patent 3 507 662 concerns a feed supplement in which the protein content i primarily protected from rumen degradation by cross-linking with natural tannins. Th specification includes examples showing that the protein is indeed, protected but there i 25 no exemplification of body weight response.
  • US Patent 3 541 204 concerns the encapsulation of biologically active substance such as amino acids, vitamins and drugs with hydrogenated fats to protect them fro rumen degradation.
  • finishing steers fed encapsulate methionine over a 10 week period exhibited weight gains which were of the order of 22 o better than those of animals on an unprotected control diet.
  • feeding encapsulated methionine over 30 days resulted in weigh gains approximately 14% better than those of animals on the control diet.
  • Australian Patent 402 712 discloses a supplement in which the protein, by treatmen with an aldehyde, is rendered insoluble in the rumen but soluble in the abomasum. Th 5 invention is particularly directed to increasing wool growth in sheep, however, on example indicates that sheet fed the supplement were likely to experience a 6 to 8% bette body weight response than sheet fed an unsupplemented diet.
  • Australian Patent 450 530 concerns a supplement in which the lipid component is encapsulated within aldehyde cross-linked protein to prevent reaction with rumen contents. The supplement is designed to permit modification (in particular to increase the unsaturation level) of ruminant meat and milk fat, and the feeding of high energy diets without digestive disturbance. The patent does not reveal that the supplement has any effect on growth rate.
  • the present invention makes use of nutritional materials protected against rumen degradation, but offers the possibility of achieving food conversion significantly in excess of that previously reported. Additionally, the invention offers considerable scope for modifying carcass fat/protein ratios to meet market requirements. It is based on the discovery that simultaneous feeding of controlled amounts of protected protein and protected lipid results in increases in feed conversion, growth rate and carcass yield, which are greater than anything that might reasonably have been expected from past experiences of feeding such supplements independently, ie. there is a synergistic effect. Moreover the increases are of a magnitude which will almost certainly prove economically attractive to the producer.
  • Figure 1 shows the relationship between body weight and the weight of carcass protein and fat for beef cattle.
  • the period A is the period of maximum muscular development, that is, when weight gain derives mainly from protein production - often called the “growing phase”.
  • the breakpoint B
  • a method of improving the growth rate and modifying the carcass quality of ruminant livestock which comprises simultaneously feeding to the livestock, protected protein and protected lipid in ratios selected to meet protein and energy requirements favourable to the achievement of desired carcass characteristics.
  • a method of improving the growth rate and modifying the carcass quality of ruminant livestock which comprises simultaneously feeding to the livestock, protected protein and protected lipid ratios varying from about 3: 1 to about 1: 1 during the growing phase to about 1 : 1 to abo 1:3 during the fattening phase.
  • a method improving the growth rate and modifying the carcass quality of ruminant livestock whi comprises simultaneously feeding to the livestock, protected protein and protected lipid ratios substantially the same as the carcass protein/fat ratios indicated in Figure 1.
  • the term "simultaneous” is used to mean feeding within a peri of about 24 hours, ie. to realise the benefits of the invention it is not essential that t intake of protected protein and protected lipid takes place at the same time, rather it important that within a given 24 hour period the animals blood plasma is enriched wi both protein and lipid constituents by absorption from the abomasum or lower digesti tract.
  • protected we mean treated so as not to be fully exposed to the degradati action of the rumen environment, but available for absorption from the abomasum lower digestive tract.
  • Suitable techniques should allow accurate control of the amount of cross-linking th occurs between the protein feedstuffs and the aldehyde; this may be achieved by varyin the amount of aldehyde relative to the protein content and its amino acid composition, s that the protein is optimally "protected” from rumen degradation, but may be completel digested and absorbed from the small intestine.
  • t optimal degree of rumen protection lies in the range 50 to 70% , ie. 50 to 70% of t protein content of the supplement will pass undegraded through the rumen.
  • Likewis dietary fats can be protected from ruminal metabolism by encapsulation in a matrix cross-linked proteins, and here the preferred window of protection ranges from 65% t 90% , especially 75% to 90% for fats derived from various sources; ie. 75% to 90% the fats will pass undegraded through the rumen.
  • the invention is not to be construed as requiring the continual, simultaneous feeding of protected protein and protected lipid throughout the growing and/or fattening phases.
  • the benefits possible from practising this invention can be expected to be related to the continuity and period of feeding the protected materials, and to amounts fed, but other factors such as target markets and cattle specifications, eg. genotype, age, and physiological condition; the environmental situation (temperature, humidity), should also be taken into account when deciding on the feeding regime to be adopted.
  • the feeding of protected protein and protected lipid in the proportions of about 3:1 to about 1:1 for approximately 90 to 100 days would be recommended for optimum feed conversion, growth rate and carcass yield.
  • the better procedure would be to change the proportion of protected protein to protected lipid from about 1: 1 to about 1:3 as the body weight of the animal increases from 400kg to 700kg during a 150 day feedlot period.
  • the invention embodies a practical feeding strategy with considerable flexibility to satisfy the various phases of growth and fattening.
  • SSM Sunflower seed meal (NOT protected)
  • PSM Protected sunflower seed meal
  • PCS Protected canola oil seed
  • Example HI Two hundred Hereford steers, average weight of 280kg, were assigned to two groups of 100 and received the following barley based concentrate ration. The results are shown in the followin table:
  • SSM Sunflower seed meal (NOT protected)
  • PSM Protected sunflower seed meal
  • SSM Sunflower seed meal (NOT protected)

  • PSM Protected sunflower seed meal
  • PCS Protected cotton seed lipid supplement
  • SSM Sunflower seed meal
  • PSM Protected seed meal
  • PCS Protected cotton seed lipid supplement
  • the present invention makes use of nutritional materials protected against rume degradation, but offers the possibility of achieving food conversion significantly in exces of that previously reported. Additionally, the invention offers considerable scope fo modifying carcass fat/protein ratios to meet market requirements. Practise of thi invention can be expected to offer economic benefits irrespective of the type of animal i question, however, a particular benefit will be observed with what might be called "hig weight" steers, ie. steers above about 400kg.

Abstract

L'invention se rapporte à des techniques permettant d'améliorer l'efficacité de la conversion des aliments, le taux de croissance et le rendement en viande du bétail composé de ruminants. Selon l'aspect le plus général de cette invention, un procédé permettant d'améliorer le taux de croissance et de modifier la qualité de la carcasse des ruminants est décrit, ce procédé consistant à alimenter le bétail en protéines protégées et en lipides protégés selon des rapports choisis pour satisfaire les besoins protéiques et énergétiques favorables au développement des caractéristiques de carcasse requises.
