PIEDMONTESE | PROFILE COW/CALF INSIDER Predicting Time of Calving Glenn Selk , OSU Extension Cattle Reproduction Specialist One of the advantages of fall-calving compared to spring (late winter) calving is the pleasant weather that the cow calf operator finds at 2:00 AM when he or she goes out to check the heifers. The downside of fall calving is the fact that these cows and heifers are not being fed from the truck or hay feeder. In most years, they are getting plenty of nutrition from the standing forage in the pasture. Therefore, the rancher will have less influence on the time of day that the cow goes into labor. As has been documented many times, if the cows are fed late in the day, a higher percentage of calves will come during daylight hours. Very precise records about the previous history of adult cows may give some help to that portion of the herd. Oregon State and Utah State Universities conducted an interesting study to determine whether individual beef cows display a repeatable pattern of calving time from year to year. Cows in this study ranged from 3 to 7 years of age and the number of calvings per cow ranged from 2 to 5, resulting in 523 parturitions for 201 individual cows. This data was gathered in late winter/spring calving seasons which began in late January and ended in late April. Cows were fed each day in late afternoon. Days were divided into 6 periods of 4 hours each. The percentage of cows calving within each period was: 6 AM – 10 AM, 34.2%; 10 AM – 2 PM, 21.2%; 2 PM – 6 PM, 29.8%; 6 PM – 10 PM, 8.4%; 10 PM – 2 AM, 4.4%; and 2 AM – 6 AM, 1.9%. By feeding late in the day, 85.2% of the calves came between 6 AM and 6 PM. Average time of day of calving was determined for each cow. The difference between the individual’s average and her calving time for each year was then calculated. The average difference for all cows was plus/minus 2.65 hours. Statistical analysis confirmed the average difference was significantly less than 3 hours. These results indicated that for this herd of cows, which was fed in late afternoon, the time that calving will occur may be predicted within about 2 to 3 hours based on the average time of day that a cow had previously calved. The authors noted, however, that alteration of feeding time could affect the predictability of calving time. Unfortunately, two-year olds do not have previous records to predict their calving time.

Hot Weather in Late Pregnancy Affects Gestation Length Glenn Selk , OSU Extension Cattle Reproduction Specialist Fall-calving cows and heifers don’t always read and follow the published gestation tables for their respective breeds. It is has been reported on several occasions that fall calving cows have lighter birth weights than spring calvers. Part of the reason for those lighter births may be attributed to shorter gestation lengths. Oklahoma State University physiologists studied early fall (August) and late fall (October) calving cows. Data from two successive years were combined for 50 Angus X Hereford crossbred cows. (Source: Kastner, Wettemann, and coworkers. 2004 Southern Section of American Society of Anim. Sci. Abstract 77). The “early” and “late” fall calving cows had been artificially inseminated in early November or early January, respectively. Semen from the same sire was used for all cows. All cows were exposed to a single cleanup bull for 35 days at 4 days after the AI season. The weather prior to calving was significantly different for late pregnancy in the two groups. The average maximum temperature the week before calving was 93 degrees F. for the “early” fall group. The average maximum temperature the week before parturition in the “late” calving group was 66 degrees F. There was a 100% survival rate for calves in both groups and both groups of cows had very high re-breeding rates (93% and 96%, respectively). The average gestation length for the “early fall” cows was 3 days shorter (280 days) as compared to the “late fall” cows (283 days). Producers with early fallcalving cows should expect calves to start coming several days ahead of the “textbook gestation table” dates. They should begin their routine heifer and cow checks at least a week to 10 days ahead of the expected first calving date. Therefore this would be good time to read the new Oklahoma State University Extension publication called “Calving Time Management for Beef Cows and Heifers”. E-1006. This is an excellent review of calving management ideas for the experienced rancher as well as the new participant in the beef industry. FALL 2008 PIEDMONTESE | PROFILE 25
DID YOU KNOW Notices: Did you KNOW From: The PAUS Board Due to the present market difficulties for the sale of both seedstock and feeder calves the PAUS board has decided to postpone the Fall Production Sale until October of 2009. This decision has been made in order to ensure a viable sale for the future. The sale objective is to bring a healthy number of producers and buyers together and to create sale prices that are mutually beneficial. This year it will not be possible to meet that objective. We apologize for any inconvenience this may cause. From: The Show Committee PAUS blocked 22 rooms at the Ramada Inn out side gate 4 of the Louisville Show. They will hold the rooms until October 15, 2008. The cost of each room with tax is $103.53. For reservations call 1-502-637-6336. There are other motels in the area but no rooms are blocked, check the internet or call for prices and availability.
