SDSU Extension Offers Feedlot Shortcourse, BQA Transportation Training Opportunities

July 16, 2019

SDSU Extension is offering an opportunity for cattle feeders to sharpen their management skills and improve their profit potential by participating in the 2019 Feedlot Shortcourse. During the shortcourse, a training will also be offered for participants to obtain Beef Quality Assurance Transportation (BQAT) certification.

Keeping Your Vaccines Viable

Vaccines are a vital part of keeping all livestock healthy. Vaccines help in the prevention of disease, which results in less utilization of antibiotics due to fewer sick animals. A valid vet-client-patient relationship will help you as you select the vaccine of choice for your livestock health program.

Ensuring Quality Milk Replacer Through Proper Storage

Milk is the source of nutrients in newborn mammals. When mother’s milk is not available, a milk replacer is utilized. To ensure the proper growth and health of the young newborn, it is critical provide a quality milk replacer and proper storage of this product is a key component for success.

Understanding and Mitigating Heat Stress in Young Dairy Animals

We often don’t focus as much on heat stress in young dairy calves and tend to focus more on cold stress. However, it is just as important and producers or calf raisers should have a plan in place to help mitigate heat stress in these animals also.

Dietary Carbohydrates in Heat-Stressed Dairy Cows

Rumen acidosis results from an excessive acid load in the rumen not neutralized by salivary or feed buffers. Changes in physiology, metabolism, and behavior of heat-stressed cows increase their susceptibility to both sub-acute (SARA) and acute acidosis.

Panting increases, respiration rate, loss of carbon dioxide (metabolic alkalosis) loss of saliva's bicarbonate (drooling), increased water losses.

Dealing With Heat Stress in Dairy Cows

Alleviating heat stress is critical to milk production. Heat stress from high environmental temperatures can be compounded by mistakes in managing and feeding cows. Water is your first concern during periods of high temperatures.

Water Importance in Lactating Dairy Cows

When considering the importance of water in lactating cow diets, we need to remember that milk is 87 percent water, and its consumption is directly correlated with milk production and feed intake. Water also makes up anywhere from 55 percent to 70 percent of the body weight of a lactating dairy cow, depending upon the phase of the lactation cycle.
