Presentation Transcript

  1. CP/Lys Requirements – Exercise • Change from previous NRC • CP for maintenance • Developing muscle during exercise • N lost in sweat

  2. CP/Lys Requirements – Exercise • CP (g/d) = (BW kg x 1.26) + (BW kg x muscle gain) + ((BW kg x sweat loss x 7.8 g/kg)/0.5/0.79)

  3. CP/Lys Requirements – Exercise • Muscle gain; sweat loss • Light = 0.089 g CP/kg BW; 0.25% • Moderate = 0.177 g CP/kg BW; 0.50% • Heavy = 0.266 g CP/kg BW; 1% • Very heavy = 0.354 g CP/kg BW; 2%

  4. CP/Lys Requirements – Exercise • 500 kg gelding, moderate exercise • CP (g/d) = (BW kg x 1.26) + (BW kg x muscle gain) + ((BW kg x sweat loss x 7.8 g/kg)/0.5/0.79)

  5. CP/Lys Requirements – Exercise • Lys (g/d) = CP (g/d) x 0.043

  6. CP/Lys Requirements – Exercise • CP (g/d) = (500 kg x 1.26) + (500 kg x 0.177 g/kg) + ((500 kg x 0.005 x 7.8 g/kg)/0.5/0.79) = • CP (g/d) = 630 g + 88.5 g + 49.4 g • CP (g/d) = 768 g • Lys (g/d) = 768 g x 0.043 = 33 g

  7. Other Nutrients – Exercise • Lost in sweat – water, salt • Cool temps – 2 to 3 oz/day • Hot temps – 4 to 6 oz/day • Vit A, E, thiamine (B1), folacin • Increased energy production • Vit E, Se • Prevent tissue damage

  8. Vit/Min Supplement – Exercise 3-oz/hd/d
