Principles of Animal Nutrition - Feedstuffs

Flashcards based on key concepts from the Principles of Animal Nutrition lecture focused on feedstuffs.

Soilage

Herbage cut and chopped in the field and fed to animals in confinement.

Silage

High-moisture forages fermented anaerobically, producing lactic acid.

Corn (Maize)

A highly digestible cereal grain that serves as a standard for energy comparison in other grains.

Amino Acids

Building blocks of proteins, some of which are limiting in certain feedstuffs.

Lysine

An essential amino acid often deficient in cereal grains like corn.

Sorghum

A cereal grain with a protein content around 11%, limited by lysine and threonine.

Wheat

Cereal grain with a protein content of 13-15%, highly digestible and palatable.

Barley

A cereal grain higher in lysine and tryptophan than corn but lower in energy value.

Oats

A cereal grain suitable for breeding stock in ruminants, with higher protein than corn.

Protein Concentrates

Feed ingredients high in protein sourced from animals or plants.

Meat/Bone Meals

Protein concentrates banned for ruminants due to BSE risk, used in swine and poultry.

Blood Meals

Highly protein-rich feed for early-weaned pigs, though low in isoleucine.

Poultry Byproducts

Protein sources from poultry, especially feather meal, which requires cooking.

Milk Proteins

Expensive protein supplements used in milk replacers, prone to quality loss when overheated.

Fish Meals

High-quality protein sources from fish, rich in lysine, often used in swine and poultry feeds.

Soybean Meal

Highly digestible plant protein source with limiting amino acids of methionine and lysine.

Cottonseed Meal

Plant protein source with a protein content of 41%, having gossypol, a toxic compound to nonruminants.
