Cattle have an upper critical temperature 20 degrees cooler than humans. When humans are a little uncomfortable at 80 degrees and feel hot at 90 degrees, cattle may well be in the danger zone for extreme heat stress.
During hot summer months, the water needed for a cow herd often determines several other management decisions, but you should expect most spring calving cows need at least 24 gallons per day.
Producers should exercise caution and test forages before cutting or grazing shortly after a drought-easing shower. Some of the greatest concentrations of nitrate in forages will be recorded at this time.
If a small cow operation can market a sizeable number of calves together in one lot, it will realize a greater price per pound (on the average) than similar calves sold in singles or small lots.
Identifying and early culling of replacement heifers that failed to become pregnant during the breeding season is more important that ever.
Deciding on the use of one calving season or two calving seasons is a big first decision when commercial producers are choosing calving seasons.
Pinkeye has long been a costly nuisance with reduced beef production in the form of lower weight gain, milk production, body condition, and eventually even poorer reproduction can result from eye infections.
Weaning during very hot summer weather is stressful enough to the calves. Therefore, any management strategy that can reduce stress to the calves should be utilized.
As hay is being cut and put in large round bales, it is important to reduce hay storage losses. University of Tennessee scientists conducted a trial to compare different methods of storing round bales of grass hay.
Producers who want to improve the genetic makeup of their beef herds often turn to AI as a tool to accomplish that goal. Many times, these producers have very high expectations as they begin the first season of AI.
Making certain your cows, heifers, and bulls are receiving the minerals that they require is one of the chores that can be easily overlooked during the busy summer season.
Producers who synchronize and artificially inseminate replacement heifers or cows have already begun the process. If hot weather arrives during the AI season, some management and breeding alterations may be helpful.
Vaccines can cost more than $3.00 per dose, and if not stored properly they can be rendered ineffective. Producers cannot afford to overlook the importance of how they store vaccines and handle them prior to injection.
Spring breeding seasons need to stay on time. Breeding seasons occurring during extremely hot weather can impact pregnancy rates in several ways.
Before the breeding season begins a few simple management procedures involving your bulls can increase the likelihood of a high pregnancy percentage among your cows.
