Title: Notes on Selecting and Feeding 4H Market Lambs


1
Notes on Selecting and Feeding 4-H Market Lambs
  • Ron Torell, Area Livestock Specialist

2
  • Live animal shows identify one animal as the
    Grand Champion. This gives the impression that
    this particular animal is far superior to the
    remainder of the class. In reality, several of
    the animals in that class may have equal product
    value and yield the same eating experience.

3
Lamb Yield grade 1 to 5 Determining Factors
  • External fat cover
  • Rear leg size
  • Kidney Pelvic Heart
  • Hot Carcass Weight

Select the feeder lamb with the end product in
mind Calculate Correct Starting Weight
  • Estimate Finish Weight
  • Frame, breed, genetics, age, ration
  • Determine Days on Feed (DOF)
  • Days until fair
  • Multiply DOF by Predicted ADG
  • Be conservative when estimating ADG
  • Subtract from desired finish weight

12
Select the feeder lamb with the end product in
mind Estimating Starting Weight (Lamb)
  • Finish weight of 135 pounds
  • Medium framed Suffolk
  • 90 day feeding period
  • June 1 to September 1
  • 90 DOF X 0.95 Lbs. per day 85 Lbs.
  • you estimated the lamb will gain 85 Lbs.
  • 135 Lbs. minus 85 Lbs. 50 Lbs.
  • Choose an April or May born lamb that weighs no
    less than 50 Lbs.

13
Select the feeder lamb with the end product in
mind
  • Correct wt. age for fair date nutrition
    program
  • Put the muscle where the money is at.
  • Long bodied
  • Wide, long loin
  • Well muscled rear leg
  • Moderate framed
  • Eye appeal
  • Homegrown

14
Factors Affecting ADG
  • Genetics and breed
  • Growth stage of feeding period
  • Type of ration
  • Experience of manager
  • Temperature and facilities
  • Frequency and scheduling of feedings
  • Amount of roughage in diet
  • Fed separately?
  • Health status parasites

Nutrition Tips
  • Commercial feeds versus mix your own?
  • starter, grower, finisher
  • Higher protein feeds early
  • Higher energy feeds late
  • Put on extra weight early
  • Expect rapid gains early
  • Expect slow gains last 40 days
  • Better to over finish versus under finish
  • Feed for finish wt. not fair maximum sale wt.

17
Match Nutrition to ADG Divide feeding period into
thirds
  • Starter - higher in protein lower in energy
  • Grower reduced protein higher energy
  • Finisher high in energy lower in protein

18
Nutrition Tips
  • Assume 3 body weight consumption
  • Increase concentrate gradually (ring method)
  • Weigh feed
  • May have to limit feed roughage (hay)
  • Weigh animal every 30 days and adjust ration
  • Target weight - todays weight divided by days
    on feed
  • 135 Lb. TW 90 Lb. 45 Lbs. to reach goal
  • 45 Lbs. / 50 days 0.90 ADG required

19
Check Weights
  • Weigh animal under same conditions each time
  • Livestock scales, bathroom scales, tapes, visual
    estimate
  • Adjust nutrition program accordingly
  • Do not weigh too often (second guessing)

20
Recognizing Finish on a Lamb Fat Deposition
  • Knuckle method over ribs
  • Physical appearance
  • Experience
  • Carcass evaluation programs

21
Keeping Animals Healthy at Fair Time
  • Why do animals get sick???

22
What are the challenges?
  • Infectious diseases
  • Bacteria
  • Viruses
  • Parasites
  • Non-infectious diseases
  • Feed
  • Poisons
  • Allergic reactions
  • Injury
  • Tumors

23
RAISE THE RESISTANCE LOWER THE CHALLENGE
24
Tips on how to raise resistance
  • Reduce stress on animal
  • Feed water often at fair, avoid overfeeding
  • Halter break gentle well in advance of fair
  • Radio, people and hauling
  • Genetically gentle animal
  • Temperature control
  • Vaccinations
  • Parasite control
  • Apply common sense

25
Tips on how to lower the challenge
  • Sanitation
  • Animal health checks by fair management
  • Leave sick or infected animals at home
  • Parasite control
  • Do not share feed pans water buckets
  • Do not share tack and equipment
  • Keep animals separate from infected animals
  • Apply common sense

26
Quality assurance Become BQA Certified http//bqa.
wsu.edu/
  • Use only approved products
  • Read and follow label directions
  • All injections
  • Under the skin in the neck region
  • Clean, sharp needle
  • Sanitary conditions
  • Keep records
  • Adhere to withdrawal times!!!!

27
Minimum Recommended Health protocol
  • 7-way (enterotoxemia) expect local reaction
  • Parasite control
  • Fresh water
  • Sound nutrition
  • Protection from environment
  • Sanitation
  • Low Stress

28
Challenges of Selecting Feeding Market Lambs
for a County Fair
  • Specific finished date vs. physiological date
  • Availability of feeder lambs of correct age
  • Novice showman
  • Too much misinformation
  • Time competition i.e. FFA, baseball games
  • Competitive factor

29
Calculate Breakeven
  • Total Expenses / Sale weight of animal
  • 220 / 135 Lbs. 1.62 / Lb.

To Make The Best Better
  • Keep winning in perspective
  • Winning is nice but making friends and new
    experiences is a much more worthy goal.
  • If you give your best you already won.
  • Sometimes you win when you should not have.
  • Sometimes you should have won when you did not.
