what are the 6 steps in formulating rations

1. describe the animal
2. describethe nutrient requirements
3. describe the feedstuffs
4. describe the feed delivery system
5. describe te ration or diet
6. describe the results

2

feed intake

increased by adjusting
animal comfort
access to feed, time conditions n competition
physcal form of feeds
water content
palatability
proper balace to ehance digestion

3

how can energy density be increased or decreased

adding fats
increasing fiber

4

corn is lysine ...

deficient but soybeans has it

5

the more mature the plant the fiber

is less digestable

6

macrominerals are

ground rock

7

microminerals

added to diets
interacts with other microminerals
copper and molybdenum are competative
interact with other nutrients

8

vitamins

also added to the diet
water soluble vitamins are not usually needed

9

describe the diet using the pearson square

take percent nutrient subtract from middle number. sum is the sum of columns one and two

10

cut and fit formulation

start with largest components (fiber in ruminants)
add minerals and vitamins
fill space with energy sources

11

lest cost diet formulations

linear programming.
results depeend on the nutrient and feedstuff constrainnts nd the prices of feeds used.
potentially dangerous to use
