    1. Equine ScienceClasses of Feeds Marshal Stork Tarleton State University

    2. Classes of Feeds • Roughages • Concentrates • Supplements

    3. Roughages • High in Fiber • Low in Energy • Pasture • Hay • Forage Crops • Silage

    4. Hay • Most common form of roughage • Many variables affect hay quality • Plant Species • Rainfall • Stage of plant growth • Harvesting Procedures

    5. Coastal Bermudagrass Hay • Can be cut 4-5 times per year • Value can be increased by mixing in legumes

    6. Sudangrass Hay • Cut in early bloom stages for maximum nutrient quality • May be toxic if harvested early • Prussic Acid • Similar to Johnsongrass

    7. Alfalfa Hay • Highly Palatable (acceptability of taste) • High in Protein (18%-19%) • Good Source of Vitamins A and B • Higher Priced (Bale = $7-$10) • 5-8 cuttings (not all are clean) Cubes

    8. Clover Hays • Nutritious • Similar to alfalfa • Difficult to cure • 14%-16% protein • Mostly raised for pasture, not hay

    9. Pasture • Native is most common • Grasses, legumes, and forbs • Generally, pasture should be a mixture of 1-2 grasses with 1-2 legumes. • A mature horse requires a minimum of 2 acres

    10. Review – Hays and Pasture • What is the most common form of roughage? • What can you do to improve the value of bermudagrass hay? • Name 1 advantage to alfalfa hay? • Disadvantage? • What is the main disadvantage of clover hays?

    11. Concentrates • Low in fiber and high in energy • Grains • Grain by-products

    12. Concentrates • The concentrate part of the ration contains the grains • Higher in energy • Lower in fiber • Most Common • Oats • Barley • Corn Than Roughages

    13. Oats • Most Popular grain fed to horses • High fiber content (13%) • More bulk per nutrient content • Must eat more to satisfy nutrient content • Less likely to founder or colic • Cleanliness is a must • Dust feeds can lead to respiratory problems • Whole or processed

    14. Barley • Comparable to oats • Lower in fiber • Weighs more per unit volume than oats Barley Oats

    15. Corn • Very “energy-dense” • Large amounts of carbohydrates • Excellent for horses that require a lot of energy • Working horses • Race Horses • Low in protein • High weight per unit volume

    16. Molasses • A popular component of mixed concentrates • Palatable • Cheap source of energy • Can reduce the quantity of dust in feed • 5% of the ration - recommended

    17. Review - Concentrates • What are the three most common types of concentrates? • What is one advantage to a high fiber content? • What is the most notable thing that corn adds to a diet? • What is one way to reduce the dust in my feed while also making it more palatable for my horse?

    18. Supplements • Can help correct deficiencies in protein, minerals, and vitamins. • Increases nutritive value • 4 common types • Protein • Vitamin • Mineral • Combination of all three

    19. Protein • Higher requirement for horses that are: • Growing • Lactating • In later pregnancy stages • Eating poor quality roughage • Performance animals (high stress) • Converted to energy by the horse

    20. Protein • Examples of protein supplements include: • Alfalfa • Linseed • Soybean • Cottonseed Meal

    21. Vitamins • Horses derive no benefits from “extra” vitamins. • Supplements for Vitamin A: • Fish liver oils • Liver meal • Supplements for Vitamin B: • Dried brewer’s yeast • Dried legumes

    22. Vitamins • Supplements for Vitamin D: • Suncured hay • Exposure to sunlight • Supplements for Vitamin E (usually not necessary): • Alfalfa pellets

    23. Minerals • Frequently needed to balance the mineral content of rations. • Most common deficient minerals are: • Calcium • Phosphorus • Sodium chloride

    24. Minerals • Supplements for Calcium and Phosphorus: • Steamed Bone Meal • Dicalcium Phosphate • Supplements for sodium chloride: • Salt block

    25. Review - Supplements • Name two situations where a horse might need protein supplements. • T/F – Vitamins supplements are always a must for horses. • What is a good supplement for vitamin D? • T/F – Alfalfa pellets are a good supplement for vitamin E. • What is a good supplement for a sodium chloride deficiency?

    26. Group Activity • Divide into groups • Discuss scenarios

    27. Scenario 1 • I have a horse that I am feeding coastal hay to. I want to add some value to next year’s hay – what can I plant with my coastal Bermuda?

    28. Scenario 2 • I am looking to buy a place to put my horses. I want them to graze on pasture grass. Approximately how many acres do I need to buy to support 23 horses?

    29. Scenario 3 • I just bought a race horse who has a deficiency in vitamin B. • What can I feed him to increase his energy level? • What can I give him to supplement for Vitamin B?

    30. Any Questions?
