animal nutrition Flashcards
nutrient requirements
water ,
energy,
protein
vitamins
minerals
what is energy
energy is carbohydrates( simple or complex fats) and protein ( atp )
what is a nutrient classe
substrates that provides specific nutrients
what are the different nutrients classes
water,
carbohydrates ,
fats,
amino acids,
vitamins(fat soluble and water soluble
minerals (macro.micro)
water function
transport (via blood) other fluids like
nutrients,
waste produces,
c2 /co2 and
hormones
lubrication
effects of friction
cooling
temperature regulation = homeotherms
exception is a camel
what do we focus on first when balancing rations
energy
energy is the most limiting nutrient
true
energy is carbohydrates what are the different carbohydrates
monosaccharides, disaccharides and polysaccharides
energy an also be in the form of
lipids
where does energy go ?
gross energy
digestible energy
metabolic energy
net energy
maintenance
production
protein =
amino acids
how many essential amino acids must be in a diet
9 but there are 20 in all
what is a complete protein
has all 20 amino acids
protein in ruminants
in diet to digest microbes
2 different minerals
macrominerals and microminerals
what are macrominerals
there are 7 increase amounts required
calcium = bone teeth muscle and nerve function
sodium, potassium, chlorine
what are vitamins and what soluble are they?
fat soluble can be stored in organisms and protected by metabolic breakdown
what are the different fat soluble vitamins
vitamin A - cell growth
vitamin D- bone formation
vitamin E- red blood cell
vitamin K- clotting function
what are water soluble vitamins
can be stored in organism= protected from metabolic breakdown
what are the different water soluble vitamins
vitamin C= antioxidants
vitamin B
B- complex- steps of metabolism
what are roughages
plant compnents ( not grain , fruit) - stem leaves and flower
they are high in cellos
what is the importance of roughages
food substrate for microbial digestion and to maintain gastrointestinal tract
what is proteinaceous
they are roughages with 15/18% cp
alfalfa
clovers
what is a symbiotic relationship and how does it work
rhizobium spp
the bacteria take nitrogen from the air to fixate into plant + soil
nitrogen base components for amino acids
carbonaceous
low cp (grasses
what is a concentrate
energy - seed/grain and fruit ( low in fiber =high energy )
protein = plants ( crude protein)
what are nutrient additives
vitamins and minerals
what are non nutrient additives
not nutrients but influence metabolism or how nutrients are utilized
what are animal sources
greater than 60% crude protein , by-products of processing animals for human consumption
ex. blood, bone, fish, and feather meal
plant sources
oilseeds, soybeans dehull the seed cook and grind = soybean mill
cottonseed, dehull( remove seed coat) heat ( destroys the gossapal )grin cotton seed mill
ruminants can be feed cotton seed
