Winter of 2010 May Have Lingering Effects

Monday, March 15th, 2010

The winter of 2010 is being recorded as one of the most severe in recent memory. Some areas have been hit harder than others, but the effects of the cold and snow may impact your business the rest of the year.

For instance, this year’s corn crop may already be affected by the weather in Texas. The optimal time to start planting corn in the Gulf Coast and Central Texas regions is about the third or fourth week of February, with planting continued into mid- to late-March, according to Travis Miller, Texas AgriLife Extension Service agronomist.

“But the Gulf Coast has been (too) wet for four months or more,” Miller said. “Central Texas is pretty much the same. No field work has been done; no fertilizing, no land preparation. There are lots of weeds in the fields. We’re very close to planting time and absolutely no field work has been done.”

Miller said if a few weeks of clear weather were to come soon, producers could move into the fields and get some land preparation done. If the planting is delayed by only a couple of weeks, there probably wouldn’t be much detriment to this year’s crop, though there is some risk associated with late planting.

“Late planting always increases the risk of heat and drought injury when we tend to have dry and hot weather mid-summer,” he said.

After an early winter decline, cash corn prices have recovered to the $3.60 per bushel level. That puts corn into cattle feeding rations around the $7 per hundredweight level.

Despite recent gains, grain analysts expect the corn market will struggle to continue higher in the near term. That’s because large U.S. supplies and favorable South American crop weather have put pressure on the market, and demand has been called lackluster. Corn growers are also expected to increase sales of stored grain due to the market’s recent rally.

Certainly there is ample time for field work in the major U.S. corn growing areas before there is concern for a shortened crop in 2010. But this winter has also affected the price and performance of livestock that is produced with corn.

Since the market low of $80 in December, cash fed cattle prices have rallied $9 to $10. Much of that price rally is directly due to the severe winter as carcass weights are running 10 to 15 pounds below year ago levels, helping keep beef tonnage down.

The weather has also delayed placements of cattle into feedyards, which, in turn, is likely to reduce overall beef production for the year. That may translate into better prices for beef, assuming consumer demand is adequate.

Restaurants, especially on the East Coast where record snows hit last week, report dramatic declines in business, while retail outlets saw an increase in sales as consumers hunkered down. As the weather warms restaurants are hoping business picks up again. If so, demand for beef and other meats could see a significant boost that would also be supportive of prices.

Baby Calf Health

Cattle producers preparing to work spring-born calves should be taking steps now to protect their animals from the respiratory diseases, infectious bovine rhinotracheitis and bovine viral diarrhea virus.

By vaccinating calves now, the first vaccination against IBR and BVDV takes place at a time when there is comparatively less stress on a calf.

 “This gives the animal an excellent opportunity to begin the development of cell-mediated immunity,” said Glenn Selk, Oklahoma State University Cooperative Extension cattle reproduction specialist. “The calf then is re-vaccinated at weaning time.”

Selk cites the July 2008 issue of the Journal of American Veterinary Medical Association, which details a study comparing a “calf-working” vaccination program with the traditional “pre-weaning” vaccination schedule.

OSU veterinary medicine scientists, in cooperation with scientists at the Samuel Roberts Noble Foundation in Ardmore, studied the timing of modified-live virus vaccinations in beef calves.

For years, the recommendation for the timing of modified-live vaccines called for the vaccine to be administered after maternal passive immunity antibodies had decreased to negligible levels in the blood of the calf.

 “It was thought that maternal antibodies received in the colostrum would interfere with the effectiveness of the modified-live virus vaccine,” Selk said. “Therefore most viral vaccines were not administered until the calves were 4 months to 5 months of age or older.”

However, the OSU-Noble Foundation research demonstrated otherwise. The scientists vaccinated calves at 67 days of age and re-vaccinated them at weaning – 190 days – and then compared those animals with others vaccinated at 167 days of age and given a second vaccine at 190 days, at the time of weaning.

 “There was no difference in the percentage of calves protected by the vaccine due to the timing of the first vaccination,” said Dr. John Kirkpatrick, OSU emeritus professor and veterinarian who worked on the study. “The result with both vaccination schedules was improved serum antibody titers compared with un-vaccinated control calves.”

Kirkpatrick said it came as no surprise that the vaccinated calves had lower treatment costs and less mortality in the feedlot than the non-vaccinated control calves.

Before the study was initiated, all cows and replacement heifers were vaccinated after calving and 30 days before breeding with a modified live vaccination for IBR and BVDV types I and II, as well as bovine respiratory parainfluenza-3 and bovine respiratory syncytial virus, commonly referred to as PI-3 and BRSV.

 “The research suggests that the first vaccination with a modified-live virus vaccine can be administered at normal ‘calf-working’ time, provided a booster is given at weaning,” Kirkpatrick said.

Following all vaccine label directions, cows that nurse these newly vaccinated calves should have already been protected with a modified-live vaccine against the same respiratory diseases.

Calving Season

Tuesday, March 2nd, 2010

Even with the best of intentions situations exist where the calving season gets to be longer than ever intended. Conditions that result in poorer body condition at calving and breeding can lead to delayed return to estrus and a long calving season the following year. The calving seasons could get long rather abruptly due to disease outbreak or bull infertility or gradually get longer and longer over several years. Sometimes heifer development or young cow nutrition shortfalls create the problem.

Whatever the cause, long calving seasons reduce weaning weights and increase variation in those weights. To determine the best route back to a tighter calving season, it helps to review the influence of days postpartum and body condition on when cows might be expected to begin cycling again after calving.

In a 60-day breeding season, a cow that was bred on the last day of this year’s breeding season will only be 22 days postpartum at the start of the next year’s breeding season. In contrast, a cow bred on the first day of this year’s breeding season will be 82 days postpartum at the start of next year’s breeding season.

Data from over 3000 Kansas cows (Figure 1), predicts that approximately 70% of cows that are 81 to 90 days postpartum would be cycling at the beginning of the breeding season and less than 10% would be cycling when less than 30 days postpartum. If a 90-day breeding season is allowed, then the last cow to be bred is just one week from calving at the start of next year’s breeding season. If she is in good condition this cow may have one and possibly two opportunities to conceive before the end of a 90- day breeding season.
