I I Section B -- Times Leader, Thursday, June 30, 2016 by Kris Ringwali, Beef Specialist, NDSU Extension Service Bulls need to be monitored throughout the breeding season. For most, June is bull turnout time. Some lingering cows still may need to calve, but the focus is on cropping and haying because the plans for next year's feed supply are well under way. Producers wanting March-April calves already have turned out the bulls. A June 1 turnout has a pro- jected March 12 start of calving. A July 1 turnout has a projected April 11 start of calving. But do not get too focused on other activities. Bulls need to be monitored throughout the breeding season. And if the bulls are not turned out yet, keep an eye on them in their pens. A dull, droopy bull may very well mean a poor day in the breeding pen. If your bull was turned out on June 6, 62 percent or more of the cows exposed should be bred by June 27 (one heat cycle). By July 18 (two heat cycles), 87 percent of the cows should be pregnant. Remember, I am using an aver- age bull with a bull turnout date of June 6. Goals reflective of an individual producer's management calendar need to be established for bulls turned out from mid-May to mid-July or later. An achievable goal for producers turning out bulls for natural service on May 15 would be 90 percent of the cows bred by June 26. Likewise, producers with bull turnout dates of May 29, June 12 and June 26 should expect 90 percent of their cows bred by July 10, July 24 and Aug. 7, respectively. Unfortunately, the evaluation of bulls while in the breeding pasture is difficult, but the bulls still need to be monitored. Excessive cows in Producer Goals for Cows Conceived Dates when 90 percent of cows should be conceived. Bull Turnout Cows Conceived May15 June 26 May 29 July 10 June 12 July 24 June 26 August 7 heat past the second cycle should be a huge warning of potential bull problems. Only 10 percent of the cows are expected to be in heat after two breeding cycles, so if 100 cows are exposed to the bulls, only 10 cows should be cycling after 42 days of breeding. On average, that would mean only one cow in heat every couple of days. However, the obvious is not always obvious because bulls will tend to seem content and may even be somewhat distant with the cows and still have conceived calves with all the cows that were in heat. Every breeding season, someone will call and ask, "I just do not think the bull is breeding. What should I do?" The response to the first question is, "Was the bull's fertility checked?" If the answer is "yes," the producer has some reassurance. Bull fertility may change, but if the bull was healthy at the breeding sound- ness exam and remains active with no obvious health issues, the bull's fertility should not change. Bulls mate at their own pace. Ask yourself, "Was the bull in good physical condition to meet the rig- ors of an active reproductive life as the bull was turned out to the cows? Was the bull allowed some pre-breeding exercise prior to bull turnout?"

Dickey County Courthouse, Social Services, Health District and Highway Department Offices will be closed on July 4th in observance of Independence Day. Re-evaluate the bull's physical condition, body condition, feet and legs, eyes and any other indication of illness. At this point of the breed- ing season, internal rectal examina- tions are only available with a lot of work, but a producer certainly can do a visual external examination of the testes, scrotum, penis and pre- puce to note changes. Bulls can get hurt, particularly the penis while mating, and if hurt, the bull will not breed. But even given all the precautions and evalu- ations, some bulls still will not mate, regardless of their excellent physical condition and having passed the breeding soundness exam. So keep an eye on the bull, but more impor- tantly, keep an eye on the cows and monitor heat-cycling activity. For some producers, multiple sires with cows provide backup bull power; however, multiple sires also means the establishment of a peck- ing order. In some cases, bulls may fight aggressively while mating, or the more timid bull simply may chose not to mate. Two bulls in a breeding pen sel- dom sire half the calves each. One bull will tend to sire more calves. Thus, the single-mated groups have fewer dynamics of bull management but more impact if the bull fails to breed. The number of cows a bull can breed annually can be quite high. Three to four mature bulls per 100 cows are the most common quoted numbers, but some producers run two mature bulls per 100 cows if the physical ability of the bulls to breed is evident. Producers must take managerial care to assure bulls are in breeding shape prior to bull turnout. In closing, a cow is expected to start cycling following birth and prior to the bull arriving, and then settle with next year's calf. Therefore, the cow is expected to maintain an average calving interval of 365 days. When a cow fails to meet those expectations, the cull pen gate is opened and off she goes. That's a sad point, so let's make sure the problem was not the bull. As a producer, one could ask why all the cows don't conceive on the first 21 days of the breeding season. Is it the bull or is it the cows? Keep an eye on both. May you find all your ear tags.

By Dan Loy, Iowa Beef Center Director, and Grant Dewell, ISU Extension Beef Veterinarian June 22, 2016 - During a heat stress incident in southwest Iowa on July 11 and 12, 1995, an estimat- ed 3,500-4,000 cattle died of heat stress. A deadly combination of tem- peratures exceeding 100 degrees, 50% relative humidity and no wind or cloud cover centered over the region. In the Midwest, deadly com- binations such as this one are usu- ally short lived but can occur any time from June to August. Dr. Terry Mader, retired beef spe- cialist at the University of Nebraska, has noted that an incident similar to the one described has occurred somewhere in the central and north- ern plains states each year from 2009 to 2013. To prevent cattle losses during such heat events, feed- lots should implement one or more mitigation strategies. Shade.

In fact, where cattle were provided access to shade from a building or constructed shed death loss was no different than normal conditions. It is suggested to provide at least 20 square feet of shade when building structures for feedlot cattle. Water and sprinkling. In the survey, producers also indicated that sprinkling or spraying water on the cattle was effective. Cattle cool by evaporative cooling so intermittent sprinkling is one method. Cattle will also walk in and out of continu- ous sprinkling. South Dakota State University has evaluated methods ' Of wetting the feedlot SUrface in the evening to reduc'e the lot surface temperature. Signs of heat stress. As cattle accumulate heat during the day they will show multiple signs of heat stress. Initially cattle will increase respirations as they try to cool them- selves by panting. As the heat load increases, cattle will become restless and begin to drool. Even though, at this stage, cattle are spending energy trying to cool themselves they are in danger. With additional increases in the heat load cattle will begin to breathe through their mouth, which I lira is an indication that a heat mitiga- tion strategy should be implemented if it has not been initiated proactive- ly. The last indication is that cattle will protrude their tongue as a last attempt to increase cooling. These cattle are at risk of dying and even if they survive, may take time to recover. Care should be taken to not increase other stresses when trying to cool these cattle. Feed and water consumption. Expect feed consumption to decrease during periods of heat stress by as much as 20%-40%. In these circum- stanceS, cattle tend to eat more of their feed in the evening s0many ~dlot managers will adjust feed deliveries to account for this. Water consumption can increase signifi- cantly during periods of heat stress so be sure to provide adequate water and drinking space for each animal. Individual animals can consume as much as 15-20 gallons per day dur- ing these periods, so be sure to provide at least 1-2 linear inches of drinking space per animal. This may need to be increased to 3 linear inches during severe heat events to provide proper access to water. -from Drovers CattleNetwork Ire Calendar - Gun Raffle Winner June 24 Ellendale, Blown'in Insulation Closed Celt Foam Open Celt Foam , Top Soil, Snow Removal, Tree Removal, Road ng, Scraper, Loader, Dozer, Backhoe, Excavation Work MICHAEL L.
