  6. Swine Nutritional Timeline Starting Weight Days on Feed Species Slaughter Weight Grain % Swine 45 to 60 lbs. 220 to 250 lbs. 100 to 120 100 • Starting at the correct weight helps you avoid problems. • Buy at 40 to 50 lbs. 110 days before the fair. • The pig should be around 130 to 150 days old at the fair.

  7. * Lowerfigure is for barrows and higher figure for gilts. Adapted From Normal Req. from University of Illinois, July 23, 2001.Available at http://porknet.outreach.uiuc.edu

  10. Measure length and heart girth in inches. For hogs weighing less than 150 lbs., add 7 lbs. to final total. Wt. in lbs. = (HG x HG x BL)/400

  11. Measure length and heart girth in inches. Homework: Estimate a pig’s weight when the heart girth is 39 “ and the length is 42 “. Wt. in lbs. = (HG x HG x BL)/400

  13. Preliminary Grade: No. 1 = < 1.00 in. BF No. 2 = 1.00 – 1.24 in. BF No. 3 = 1.25 – 1.49 in. BF No. 4 = 1.50 & > Adjusted by Muscling Score (4.0 x BF) – (1.0 x Musc.) With thin musc. = 1, Avg = 2, and Thick = 3.

  14. Speeding Up ADG • Swine: Increase lbs. fed; Add milk or fat to feed

  15. * Lowerfigure is for barrows and higher figure for gilts.

  16. Slowing Down ADG • Swine • Substitute 10 to 15% alfalfa pellets for grain • Reduce lbs. Fed from Ad Lib by 15% • Exercise

  17. * Lowerfigure is for barrows and higher figure for gilts.

  27. You figure what you need to do! • Your fair is on September 15th. • You will buy a pig on Memorial Day. • Your pig weighs 50 lbs. when you buy it. • You want the pig to weigh 240 lbs. at the fair. • The pig needs to gain ___ lbs. in ___ days. • So, the pig needs to gain ___ lbs. / day. • Is it possible? Will the pig be too heavy, too light, or just about right for the fair for market weight?

  28. Paylean™ - Ractopamine • Feed additive; • Feed 150 to 240 lbs. live weight (last 90 lbs. live weight gain); • Feed at 4.5 to 9 grams/ton (5-10 ppm)

  30. Proper use of Paylean® in show pigs • Paylean may only be fed to finishing swine from 150 pounds to 240 pounds body weight. • Paylean must be fed in a complete ration containing at least 16% crude protein. • There are no approved extra-label uses for Paylean. Extra-label use is illegal. • Feed Paylean so your pigs receive it for approximately four weeks. • Increase total dietary lysine by 0.30% from present feeding levels.

  31. Improper use of Paylean Do not offer Paylean in a complete feed at levels less than 4.5 g/ton or greater than 9 g/ton. Do not topdress with a Type A Paylean premix or intermediate premix (Type B). Do not restrict water intake.
