Considerations in developing hay and pasture systems:
1. What are the natural resource advantages and challenges of the farm?
a. Soil & site characteristics -- Soil type & suitability (depth, drainage, etc.) -- Soil fertility -- Site topography
Considerations in developing hay and pasture systems:
1. What are my natural resource advantages and challenges?
a. Soil & site characteristics -- Soil type & suitability
(depth, drainage, etc.) -- Soil fertility -- Site topography
These factors determine what can be grown and the type of livestock system that can be supported.
Considerations in developing hay and pasture systems:
2. What are the goals & objectives of the intended grazing system?
-- Summer pasture -- Maximize grazing/minimize
Choose your species based on:
1. Species adaptation to site.
2. Species response to cutting or grazing system.
3. Potential forage yield and seasonal distribution of growth.
4. Palatability and nutritional value.
5. Persistence.

The Horse as a Social Animal.
An issue that directly effects holistic resource management.
Dr Temple Grandin - Livestock Handling and Behavior –
Colorado State University
She has owned, loved, and worked with horses all her life.
People with autism see things more as animals do.
Some comments she has granted me to use on
horse management from her book, Animals in Translation :
Page 155: Animals in Translation.
“Socializing Animals to Others Animals Anyone who interacts with
animals has to know how to manage an animals’ aggressive nature. Two
actions are essential: make sure the animals is properly socialized to other
animals, and make sure the animal is properly socialized to people.
You have to make sure animals are socialized to other animals because
most of what animals do in life they learn from other animals. Adults teach
their young where to eat, what to eat, whom to socialize with, and whom to
have sex with. The adults teach the young one social rules and respect for
their own kind. If an animal does not learn these rules when he’s young,
there may be many problem behaviors when he grows up…
Page 158: Animals in Translation.
On wild horses…. In the wild, constant fighting is not normal…
When a stallion is raised in solitary confinement he never learns normal
social behavior, and that’s what makes him dangerous to other males…
Raising young stud colts in a pasture full of older geldings will teach
them some manners and create a good stallion that you can ride like
a normal horse, People with fancy horses are actually abusing them
with too much care. Young horses need to get out and have a chance
to be horses…….
Concerning a horse she worked with called Blackie; I think that since
Blackie had never learned social skills he had never learned that once
he had Achieved dominance he no longer had to keep fighting. “
Forage Quality, Animal Behavior, and Health
Management Considerations
Why continuous grazing is like kids in a candy store.
Under continuous grazing (one paddock no animal movement).
Horses will regraze the same plants every 3-5 days when
Regrowth forage volume wise is sweeter
( think of young tender carrots.)
Rotational grazing allows for more grass maturity with
more fiber and volume wise less sugar.
More research looking at rotational grazing and sugars
needs to be done.

Rotation System Together and BMP Components
Management Considerations
How Fast - Managing by grass heights is the best.
Most grass grazing recovery is 15 – 30 days.
Time varies by time of year, heights do not.
This waiting time is necessary for grass to regrow
and be productive. (Like when you have the flu)
Less than 15 days will cause grass death
Continuous provides how much rest?

regrowth time and grazing time problems.
Complete reestablishment works the best.
Overseeding 0-20% of seeds make it.
Plan a management system then install BMPs

Soil – Plant Considerations
Simple mixes of one or two grasses
or varieties of same grass best for the site’s
climate, soil, drainage and management.
Complex mixes come on strong
And do not persist.
What is least adapted dies first
Weeds take it place.

Animal Behavior Considerations
Animals put pressure on what they
like most and ignore the rest and
Kill the best out.
An old pasture has what they don’t want.
Why keep it? Complete reestablishment is the best
and cheapest in the long run.
Animals learn what they like and that can be changed.

THE VALUE OF A HORSE GRAZING MANAGEMENT SYSTEM FOR COVER IN DOLLARS AND SENSE?
ASSUME: 6 Acres of well drained soil with a pH 6.2 with good fertility
3 horses / one fenced field / 1 watering system in place
Cost of replacement forage is $3.00 / small hay bale
Established Novel Endophyte Tall Fescue and Kentucky bluegrass on all
acres with an annual yield of 4.5 tons (9,000 lbs)/ acre
LET’S EVALUATE SOME KEY EXPENSES OVER 5 YEARS
1 PADDOCK SYSTEM 3 PADDOCK SYSTEM
Purchased hay $ 5,220 Purchased hay $ 4,860
Seeding costs (seed only) 3,000 Seeding costs (seed only) 300
Temporary fencing 0 Temporary fencing 800
Watering system 0 Portable Watering system 600
System cost $ 8,220 System cost $ 6,560
ROTATIONAL GRAZING FOR COVER DOESN’T COST, IT PAYS AND CREATES MUCH LESS RESEEDING HEADACHES!
Forage calculations were done using the NRCS Maryland Grazing Handbook and C-Graz Grazing Analysis Tool. Cost estimates were based on using basic portable fencing and watering systems.

Also suggest having a sacrifice area to prevent the worst compaction in wet field conditions.
To prevent grazing below recommended heights which will kill your grass, feed animals hay elsewhere when grass is below recommended grazing heights.

RECOVERY
LEGEND
Only about 25% of the forage yield potential will be realized due to regrazing of recovering grass plants. Grass quickly regrazed is high in sugar a concern with founder issues. Constant regrazing will cause rapid stand death.
Value of pasture forage is 45 small bales of hay / acre. Needed additional hay/acre: 58 small bales of hay costing $174 an acre or $1,044 a year or $5,220 over a 5 year expected stand life in a 6 paddock rotation.
Annual reseeding costs $100 an acre (seed only) or $600 per year.

RECOVERY
LEGEND
Age of forage should be fine for most horses. About 27% of the forage yield potential will be realized due to short regrowth time and regrazing of the grass plants, but this grass recovery time usually will maintain cover. Think about your lawn!
Pasture forage produced equals 49 bales/acre: Worth $147 an acre or $882 a year or $4, 410 over a 5 year expected stand life in a 3 paddock rotation where animals are moved when grass removal heights are reached to the sacrifice area. Additional forage needs are 54 bales/acre or $162 in purchased hay per acre or $ 972 per year or $4,860 over a five year period.
Annual reseeding costs for spot treatments should be less than$10 /acre or $60/yr (seed only).
Also need to have a sacrifice area ( Corral, field, building ) to prevent the worst compaction in wet field conditions.

Age of forage should be good for horses, medium quality needs. About 58% of the forage yield potential will be realized due to some rejection and regrazing of grass plants, but grass recovery time is adequate for all purposes.

Benefits of Rotational Grazing
Adequate Grass Recovery produces Maximum forage growth and quality. Longest stand life and cuts costs.
Greater ability to produce desired weight management with less grain and supplements.
Greatest environmental benefits. Nutrients Water Quality
