What is the Konefal method of calving management? - ANSWER -When you feed the cattle at a certain time in the day every day to get them to only calve in the daylight hours How does the ISU farm manager use pelvic measures in his management program? - ANSWER -If he knows that a cow/heifer will not have a big enough pelvic to support the birth of the calf, then he will not breed it. This saves the whole trouble of dystocia during a birth that otherwise would have most likely occurred by breeding it. Having the knowledge of the pelvic area will give you an idea of how parturition would go. How does the farm manager predict calving ease scores? - ANSWER -he measures the height from the pubic spine and the spine at the shortest distance and the width using the widest distance. Multiplies those values together to find the area of the pelvic. He wants the pelvic area to be 169 and above. What is the primary challenge and cause of death to calves presented breech? - ANSWER -When the umbilical cord breaks and the calf could suffocate in the womb if the head is not out of the womb in time What are the reasons why a commercial cow-calf producer would wish to early wean his calves? What is the biggest benefit to this person? - ANSWER -improve repro on dam better feed usage better feed efficiency better carcass quality it would be best for retained ownership Why would a feedlot operator pay a premium for early weaned calves? - ANSWER -1. better feed efficiency2. produce carcasses that reach ave choice or higher How does someone who retains ownership through the feedlot phase benefit from early weaning? - ANSWER -better feed usage (save feed costs because not as much feed) better feed efficiency better carcass quality How does a producer who sells calves at weaning financially benefit from early weaning? - ANSWER -improve repro on dam and saves feed costs and grade better What is early weaning? How old are calves when they are weaned "early"? - ANSWER -wean between 3-5 mos What is the traditional time frame in which calves are weaned? Why are calves traditionally weaned then in Iowa/most of US? - ANSWER -7 mos- when pasture runs out For what reason is creep feeding often not cost effective (don't ANSWER that feed costs are high . . is a given)? - ANSWER -very low feed efficiency about 10 lbs of feed for 1 lb of gain. Name the three categories of leasing arrangements. Define the by how they work when income is generated, and by how risk is distributed between owner and operator. - ANSWER -Cash Lease: Operator with risk, operator get someone's calves and owner gives a check Crop Share: Share in risk, owner and operator collaboratively define their cost contributions Each share income in proportion to their contribution towards costs Flexible Share: Owner Risk, when you lease cows from a parent and they will take the risk and make sure that your costs are covered first and then they're cost Is there more or less risk in a cash lease than a flexible share lease for the owner? Why is that the case? - ANSWER -Less risk in the cash lease for the owner because they just write the check and the operator is in charge of doing all the work to get the calves to make a profit For what reason would one wish to use a calf-share lease agreement? Specifically, why would they want to split the calf crop rather than the gross revenue check at market time. - ANSWER -If the operator is putting more work into it then he should want to be making more from the calf crop. In a calf share agreement, why is the payout of gross revenue not 50% to each? - ANSWER -The operator could be putting in a higher percentage to cover costs and the percentage split from the gross revenue should represent that as well. What are some criteria that should be considered in writing a lease? Offer examples (not category names). - ANSWER -1. Physical(purchasing bulls and vet) 2. Financial(culls deciding, replacements) 3. Legal(time of agreement, liability) What are two of the several factors that need be determined to calculate "cost of ownership"? - ANSWER -1. cow replacement cost 2. interest on investment 3. death loss Feedlots use step-up programs for feedlot cattle. What is a step-up program? Why do they employ them? - ANSWER -Begin by offering relatively high forage diet with low grain content laid-in - ANSWER -If you lay in an amount of something, you buy it and store it to be used later. shrink - ANSWER -A deduction of weight from the live weight of an animal, usually 3 percent for cattle off pasture and 4 percent for off-feed weights of fed cattle. bunk management - ANSWER -determine the amount of feed to offer. feed efficiency - ANSWER -The amount of feed consumed by an animal per unit of body weight gain. ionophores - ANSWER -Antibiotic that enhances feed efficiency in cattle by altering ruminal fermentation. Acidosis - ANSWER -An acute or chronic disease condition in feedlot cattle. Results from overconsumption or too rapid consumption of grain (starch). Acute cases generally result in death. Chronic cases are common and result in erratic intakes and/or reduced feed intake but probably are hidden by pen intakes, which
