  1. MAIN IDEA: • What are the measures of reproductive, production and financial efficiency in the sheep industry?

  2. Today • You need to read and take notes over the slides • You will need to be ready for a quiz on Thursday.

  3. 1. Measure of Reproductive Efficiency: • Pregnancy Rate: • Measures the number of ewes diagnosed as pregnant divided by the number of ewes exposed to a ram • Should approach 100% • Helps identify infertileewes for culling USDA photo by unknown photographer.

  4. 1. Measure of Reproductive Efficiency (cont.): • Live Lambs Born per Ewe Lambing: • Ideal is for each ewe that lambs to have twins with both lambs alive, healthy and thrifty. • With dystocia (difficult births), ram problems during the breeding season, or low fertility,this may be closer to one than the desiredtwo live lambs per ewe. • Triplets or quadruplets are frowned upon because of light birthweights and the inabilityof most ewes to raise that number of lambs.

  5. 1. Measure of Reproductive Efficiency (cont.): • Live Lambs Born per Ewe Exposed: • Includes nonpregnant ewes exposed to a ram • The number will be lower (although hopefully not much lower) than the number of live lambs born per ewe lambing.

  6. 1. Measure of Reproductive Efficiency (cont.): • Lambs Born per Ewe per Year: • Some breeds of sheep can breed andlamb year round. • Producers can take advantage of those breeds by accelerating the lambing schedule so that ewes lamb more often than once each year. • Program may attempt three lambings every two years or five lambings every three years.

  7. 2. Measures of Production Efficiency: • Percent Lamb Survival: • Divide the number of lambs weaned by the number of lambs born alive. • This number should approach 100% • May be lower if ewes give birth to a large number of triplets or quadruplets. • Lower numbers could indicate a predator problem, especially in larger Western flocks.

  8. 2. Measures of Production Efficiency (cont.): • Pounds of Lambs Weaned per Exposed Ewe: • Accounts for fertility, lambing percentage and pre-weaning growth • Poor performance reduces the number of total pounds of lambs to sell, reducing income. • Weaning age can affect this measure. • Each exposed ewe should wean at least 100 pounds of lambs in most situations.

  9. 2. Measures of Production Efficiency (cont.): • Pounds of Wool per Exposed Ewe: • Wool production is currently of relatively minor value compared to the value of a lamb • Wool income can add valuable dollars to a sheep flock's bottom line. • Between her own fleeceand the fleece of her lambs(shorn or unshorn), eachexposed ewe should yieldat least nine pounds ofwool per year.

  10. 3. Measures of Financial Efficiency: • Feed Cost per Ewe or Feed Cost per 100 Pounds of Lambs Sold: • Feed costs to maintain the ewe flock account for a majority of expenses. • Reducing feed costshelps make the operationprofitable. • Includes purchased feeds,grazing fees and othergrazing costs.

  11. 3. Measures of Financial Efficiency (cont.): • Gross Income: • The total amount of money generated from sales over the course of the year. • Reproductive efficiency counts for a major portion of gross income to sheep producers. • The other half of the equation is market price, which is largely a function of supply and demand. • Ethnic and seasonal demand for lambs can increase market price.

  12. 3. Measures of Financial Efficiency (cont.): • Net Income: • Net income is simply gross income minus the costs associated with the enterprise. • Feed costs are the major cost center. • Veterinary services, shearing, insurance, trucking, fuel and depreciation costs must also be subtracted. • Net income is simply the return to labor and management.

  13. Summary: • Efficiency of the sheep flock is no less important than efficiency for dairy, beef or swine. • Reproductive efficiency can be evaluated in many ways, but all measures aim to increase lamb or wool production. • Growth rate may be combined with reproductive efficiency to indicate the potential for increased sales. • Costs, especially feed costs, must be reduced to ensure a profitable enterprise as measured by net income.
