Protein Degradation And Utilization In Farm Animals

We are of the opinion that in the future also with the help of transcriptomics more time should be invested in researching the physiology of protein degradation and the associated protein utilization efficiency using highly standardized animal trials abstract pigs are among the most important farm animals for meat production worldwide

The concept that animals require dietary indispensable organic nitrogenous substances for proper growth and maintenance was recognized 2 centuries ago 1 2 since then our understanding of protein amino acid requirements and of the dynamics of protein metabolism including protein biosynthesis and degradation in humans and animals has grown immensely 1 2

Until the genetic influences on nutrient utilization in growing farm animals 547 mechanisms involved in controlling protein synthesis and degradation are better understood and more quantitative information on protein synthesis and protein degradation in different animal types and under varying environmental conditions becomes available it

The journal of animal physiology and animal nutrition is an animal feed science and research journal covering the physiology and nutrition of farm and domestic animals abstract protein turnover defines the balance between two continuous and complex processes of protein metabolism synthesis and degradation which determine their deposition in

We estimated ruminal crude protein degradation of twelve feedstuffs commonly used in china using in vitro and in vivo methods the in vivo net protein utilization npu levels of corn sorghum

3 whole animal and tissue proteolysis in growing animals v e baracos department of oncology university of alberta 11560 university avenue edmonton alberta canada t6g 1z2 while it is convenient to conceptualize protein synthesis as being associated with growth and protein degradation as being associated only with atrophy or senescence both processes proceed continuously in all tissues

This book addresses key issues of how energy and protein are utilized and interact in farm animals from the molecular to the whole animal and even to the herd or group level of organization it contains state of the art research and reviews on several topics of nutrient utilization and metabolism from top scientists worldwide

Pigs are among the most important farm animals for meat production worldwide in order to meet the amino acid requirements of the animals pigs rely on the regular intake of proteins and amino acids with their feed unfortunately pigs excrete about two thirds of the used protein and production of

The dietary protein source but also the microbial cp from rumen the mp systems consider both the factors thus predict the protein availability more accurately and precisely this system is aptly designed to represent the extent of protein degradation in the rumen and the synthesis of microbial protein as variable functions

Background the high dependence of intensive ruminant production on soybean meal and the environmental impact of this crop encourage the search for alternative protein rich feeds the use of insects seems promising but the extent of their ruminal protein degradation is largely unknown this parameter has major influence not only on n utilization efficiency but also on the environmental burden

This book describes current research in modelling nutrient use in farm animals from cellular to ecosystem level the chapters are developed from papers presented at a satellite meeting of the 9th international symposium on ruminant physiology held in south africa in october 1999 excellent papers from a top list of contributors

Protein digestion in the ruminant animals can be divided into two phases 1 digestion degradation in the reticulorumen and 2 digestion in the abomasum and small intestine therefore in ruminant animals dietary proteins are classified as rumen degradable and rumen undegradable proteins

Thus the efficiency of utilizing dietary protein to produce edible protein in animal products is usually higher in nonruminants than in ruminants with the highest value of 33 3 for broiler chickens during a 6 week period of growth and the lowest value of 6 7 for grazing beef cattle during a 76 week period of growth table 3 58 in addition

The concept that animals require dietary indispensable organic nitrogenous substances for proper growth and maintenance was recognized 2 centuries ago 1 2 since then our understanding of protein amino acid requirements and of the dynamics of protein metabolism including protein biosynthesis and degradation in humans and animals has grown immensely 1 2

With an exponential growth of the global population demands for animal sourced protein are expected to increase by 60 between 2021 and 2050 in addition to the production of food protein and fiber wool animals are useful models for biomedical research to prevent and treat human diseases and serve as bioreactors to produce therapeutic proteins

Diet composition grazing and environmental stress could have a significant impact on muscle metabolite composition and thereby the metabolisms to date results from farm animal muscle metabolomics have highlighted essential muscle metabolisms including energy substrate changes protein degradation and mitochondria metabolism

This book brings together the papers presented orally or as posters at the sixth international workshopon modelling nutrient utilization in farm animals held in wageningen the netherlands 6 8 september2004
