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
