Hay
Sugar beet
Alfalfa
In the form of fibre, sugar, and starch
Provides energy
Fats and oils:
What?
Why?
Vegetable oil
Fish oils
Some pure unprocessed plant based oils
Provides energy
What is Digestible energy (DE)? How is it measured?
Gross energy food contains- the amount of energy estimated will be lost in the feces Mj/kg
Low energy feed?
horse maintains weight easily
7-9 Mj/kg
Medium energy feed?
Horses in medium work or need just a little extra help maintaining condition
9-10 Mj/kg
High energy feed?
Provide energy for hard work or help increase body weight
11 Mj/kg or more
Too much or too little DE?
Too much: horse will get fat or excitable
Too little: lose weight, lethargic, irritable and prone to infection
Protein
How?
Why?
Hay and feeds - sufficient for healthy horse
Concentrates if needing help maintaining body condition
Aids the repair and replacement of body tissue, increasing resistance to disease, improving coat condition and hoof horn quality
Too little vs too much protein
Too little: delayed healing of wounds, increased vulnerability of infection, and poor coat and hoof condition
Too much: cannot be stored. Removal of excess protein from the body puts unnecessary strain on the kidneys, heart and lungs and increases water requirements
What are proteins?
22 amino acids
12 are synthesized adequately by horses gut
Lysine and methionine are likely to be deficient
Lacking specific amino acids and signs?
Lysine and methionine- hoof and coat condition
Tryptophan- increased nervousness
Why provide Vitamins and minerals?
Preserve strong bone structure and healthy teeth
Aid energy metabolism and feed utilization
Assist in the maintenance of fluid balance, nerve and muscle function
Boost efficiency of the immune system
Some:
help maintain skin coat and hoof
Act as antioxidants- help deal with infections and inflammation and prevent the decay of body tissues
Not enough vitamins and minerals results?
Difficulty maintaining weight
Prone to infection
Develop brittle bones or loose teeth
Poor hoof and coat condition
Suffer from anemia, delayed wound healing, nervousness or muscle damage
Too much vitamins and minerals?
Adversely affect the absorption and action of others
