Underperformance Flashcards
What accounts for 70% of costs on pig farms?
Feed
What is the estimate for food wasted on farm?
5-20% of feed is wasted on farm
How is food wasted on farm?
Physically: spillage, down the slats, trodden on, pests
Nutritionally: wrong feed, wrong feed scale, contamination, water, not enough, wrong flows poor access
Environmentally: severe climate, too hot or cold, aggressions,crowding, dusty, bad layout
What is phase feeding in pigs?
Matching requirements to stage of growth. Lean growth at lease cost.
What is the importance of efficient feeding?
If potential lean growth is to be fully supported, then the amoun of protein relative to energy in the diet should be reduced with increasing live weight.
Too little protein will fail to exploit lean growth potential, too much protein with reduce growth and increase nitrogen excretion.
What factor affects pork tenderness?
Growth rate
What are the 3 types mortality evaluated at pig farms?
Pre weaning mortality, post weaning mortality, and adult mortality
What is the normal time to first suckling by a piglet after birth?
25-35 min
True or false: piglets establish teat order by 4 to 6 hours
True
What is the percentage of reliability that. Piglet with go to the same teat?
About 90%
True or false: milk ejection is induced by the rear teats on a sow?
False: the front teats cause milk ejection
What are the characteristics of normal piglets?
On their feet with in 1-2 min after being born Suckling with in 2-5 min Sleep between meals, Don’t need much care First burns get the most colostrum
What are the characteristics of weak piglets?
Last in the litter/ get less colostrum Low birth weight Trouble competing Oxygen deprived IUGR head shape
How can you help weak piglets?
Help them suckle
Stomach feed colostrum, or milk replacer
Inject glucose intraperitoneal.
Make sure feed and injections are warm 35C
Why is it important to keep piglets warm after birth( 35 degrees C for 1 week then 25 C)
Born with no subcutaneous fat, no brown fat, and no hair, hey have limited capacity for gluconeogenesis, and can suffer from hypoglycemia with in 15-20 hours with out adequate suckling. Takes then 1-2 hours to raise their temp, after eating
What are ways to measure pig underperformance?
Feed/ weight
Weight and days to slaughter
Abbott our payments
Use a program: BPHS
What is the difference between production and productivity?
Productivity =the total value of output per unit time/ total value of inputs per unit of time
Why is it important to identify the resources used when evaluating performance?
The estimate of output per unit of the scarce resource should be used to measure performance
What is a technical optimum?
The maximum amount of production
What is required for an economic optimum?
Maximized profits from the difference between the value of the inputs and the value of the out puts
What is profit?
Profit is the difference between the total revenue and the total costs.
What is a break even point?
Total revenue is equal to total costs
Where on a graph of total revenue and total cost is max profit ?
Profit is maximized where the slope of the total revenue line is equal to the slope of the total cost line
What is an economic optimum?
The maximum profit
