Concentrates Flashcards
(70 cards)
Feedstuffs can be sorted into
Roughages vs concentrates
Concentrates can be sorted into
Energy sources, protein sources, vitamins, and minerals
Concentrate protein sources can be sorted into
Vegetable & non-vegetable origins
A good ration should be
Balanced, palatable, not harmful, low cost, and homogeneously mixed
What is a concentrate?
Animal feed rich in energy and/or protein but low in fibre (<18%) used with another to improve nutritive balance of the ration; intended to be diluted and mixed to produce a supplement or complete feed
What is a supplement used for
Used to improve the nutritional value of the ration complementing the nutrients in the base feed, to produce a more complete feed
Can a concentrate become a supplement?
Yes
Is there a difference between concentrates & supplements?
Yes - concentrates can be used to make supplements. Supplements complement the nutrients in base feed, but concentrates are meant to make supplements?
Energy concentrates - Cereal grains parameters
<18% CF, >70% TDN, but <20% CP
Minerals, vitamins, & aa’s - variable quantity & less important than energy
Cereal grains Energy concentrates have __________ as major component
Carbohydrates with primary role as energy source
Cereal grains energy concentrates examples
Corn, barley, wheat, oats
Cereal grains starch, fibre, and CP content
Starch - 55-75% (more amylopectin than amylose)
Very low in fibre and low CP (8-12%)
Are cereal grains fed to ruminants and non-ruminants
Yes - for non ruminants, some aa (lysine, tryptophan, threonine, and methionine are low)
Cereal grains Ca/P amount
Low Ca & high P
How much do cereal grains get used for cows, sheep, horses, pigs, poultry, companion animals
Sheep > Poultry > pigs > companion animals > cattle > horses
Energy densities of cereal grains listed in order (barley, wheat, corn, and oats)
Corn > wheat > barley > oat
Protein density of cereal grains (barley, wheat, corn, oats)
Wheat > barley > oat > corn
