Animal Nutrition Flashcards
Nutrition is required for these 3 basic needs
maintenance (HR, RR, digestion), growth, reproduction
secondary needs that require proper nutrition
production (eggs, milk, etc.), finish of meat animals, performance (racing)
why protein is needed
additional growth, reproduction, lactation, cell formation
what a protein deficiency causes
poor growth, lack of production, reproductive issues
excess protein can cause
joint disease, reproductive disease
most expensive nutritional component
protein
energy is needed for
body functions (in measured amounts)
an energy deficeincy can cause
poor growth, decreased production, no energy for handling stress/protecting against disease
an excess in energy can cause
overconditioning or obesity, joint disease, osteocondritis dissicans (OCD)
what is OCD, in what cases is it most common
osteocondritis dissicans, seen in large fast growing animals, swollen hock joint, common in horses and dogs fed an excessive high energy feed
what salt is needed for
water balance, kidney function, eliminates waste
excess v deficient salt
excess- salt toxicity
deficiency- Pica (animal eats nonnutritive things; ex: cattle eating rocks or drinking urine)
what calcium and phosphorus are needed for
needed in ratio, important for lactation
what a calcium:phosphorus deficiency causes
bone disease (osteoporosis- less dense bones)
what iron is needed for
needed for hemoglobin production in RBCs
what hemoglobin does
helps bring O2 to tissues and carry CO2 away
