The use of non-conventional animal protein (NCAP) sources as alternative feed resources for poultry production has been a topic interest in recent years. NCAP sources, such insects, have the potential to significantly reduce costs, which account 80% total costs. Insects, particular, offer protein-rich options with excellent amino acid profiles, resulting remarkable taste and market value. Howev...

Introduction Current NRC recommendations for dairy cattle provide only minimum recommendations for chemically measured fiber. However, physical characteristics of fiber can influence animal health, ruminal fermentation, animal metabolism, and milk fat production independently of the amount of chemically measured fiber. Using ground fibrous by-product feeds or finely chopped forages in rations t...

The objective of this study was to investigate antimicrobial activity, during the storage period, of animal feed and any effects on in vitro rumen digestion by supplementing different levels (5.55, 11.1, and 22.2 g/kg) of freeze dried citrus peel (FDCP) to the feed compared to untreated feed and feed treated with an antifungal agent (AA) at 0.05 g/kg. In a preservation test, feed supplemented w...

Feeds contribute highly to environmental impacts of livestock products. Therefore, formulating low-impact feeds requires data on environmental impacts of feed ingredients with consistent perimeters and methodology for life cycle assessment (LCA). We created the ECOALIM dataset of life cycle inventories (LCIs) and associated impacts of feed ingredients used in animal production in France. It pro...

In this paper we present a polymerase chain reaction (PCR)-based method for detecting meat and bone meal (MBM) in compound feedingstuffs. By choosing adequate DNA targets from an appropriate localisation in the genome, the real-time PCR method developed here proved to be robust to severe heat treatment of the MBM, showing high sensitivity in the detection of MBM. The method developed here permi...

One of the great contributions of Armsby to the science of animal nutrition was the demonstration that the requirements of animals for nutrients, and the values of feeds in covering these requirements, are two separate and distinct problems, requiring different experimental methods for their solution. The requirement of an animal for energy, for example, must involve a study of the heat product...

In the intensive livestock production systems, with decrease in grazing land and intensification of agriculture, the animal feeds are most likely to be contaminated with pesticides, dioxins, radionuclide, heavy metals, bacterial, fungal / mycotoxin contaminants etc., which may , market, it is the need of the hour to produce the livestock products free from contaminants. The feeds and fodders ar...

Phytases are a group of enzymes capable of releasing phosphates from phytates, one of the major forms of phosphorus (P) in animal feeds of plant origin. These enzymes have been widely used in animal feed to improve phosphorus nutrition and to reduce phosphorus pollution in animal waste. This review covers the basic nomenclature and crystal structures of phytases and emphasizes both the protein ...

Livestock, particularly ruminants, can eat a wider range of biomass than humans. In the drive for greater efficiency, intensive systems of livestock production have evolved to compete with humans for high-energy crops such as cereals. Feeds consumed by livestock were analysed in terms of the quantities used and efficiency of conversion of grassland, human-edible ('edible') crops and crop by-pro...
