Trophic Efficiency

Trophic Efficiency

Trophic level transfer efficiency (TLTE) is a measure of the total energy transfer from one trophic level to the next. Due to extensive energy loss as metabolic heat, an average of only 10% of the original energy obtained is passed on to the next level. This pattern of energy loss severely limits the possible number of trophic levels in a food chain.

Overview of Protein Metabolism

Overview of Protein Metabolism

Proteins are broken down into amino acids during digestion. Unlike fats and carbohydrates, which are stored for later use, proteins are not. Instead, amino acids are either used to produce ATP through oxidation or contribute to the creation of new proteins for the growth and repair of the body. Any surplus amino acids from the diet are converted into glucose or triglycerides rather than excreted.
Amino acids play various roles in the body once they are absorbed into cells. They are restructured...

Area of Science:

Livestock Science
Metabolomics
Animal Nutrition

Background:

Metabolomic technologies are advancing livestock feed efficiency (FE) understanding.
This offers new avenues for improving ruminant production profitability and sustainability.

Purpose of the Study:

To systematically review metabolomics methods for assessing FE in ruminants.
To synthesize findings on biological mechanisms influencing FE variations across species.

Main Methods:

Comprehensive literature search of PubMed, Web of Science, and Scopus (1971-2023).
Systematic evaluation of 71 studies applying metabolomics to FE in cattle, sheep, goats, and buffaloes.

Main Results:

Cattle studies predominantly used targeted metabolomics to identify biomarkers like amino acids and fatty acids.
Key metabolic pathways identified include energy metabolism, nitrogen utilization, and muscle development.
Challenges include small sample sizes, inconsistent methods, and limited validation, especially for non-cattle species.

Conclusions:

Metabolomics can provide cost-effective, non-invasive molecular markers for FE evaluation.
This supports more efficient and sustainable livestock management.
Future research requires larger, species-specific studies with standardized methods for biomarker validation and practical application.
