Often, Ward Laboratories, Inc receives sorghum samples and producers want us to test prussic acid and nitrates.  My recommendation would be to send two separate samples when testing for grazing purposes because prussic acid and nitrates accumulate in different parts of the plant. Prussic acid accumulates in the leaves of the grass in contrast to...Read More

Last week I attended both the Colorado Cattlemen’s Annual Convention and the Sandhills Ranch Expo at the Ward Laboratories Inc tradeshow booths.  At both locations, producers had concerns about nitrates.  The climate and weather however were contrasting conditions.  Colorado producers wondered how drought stress might affect the nitrate levels in their forages, while Nebraska and...Read More

Weedy alfalfa is often a concern when water resources are scarce. The weeds sometimes even seem to outcompete the alfalfa in extremely dry years. Weeds can impact forage quality and contribute to toxicities. Ultimately, this reduces the value of the forage and hits the pocket book! Here are 4 reasons to make a plan to...Read More

Typically, we advise livestock producers to monitor pond water quality as temperatures rise and pond water levels drop. However, when we are in drought and starting the grazing season with low water levels and concentrated water sources. Here are five considerations for pond water quality: 1. Total Dissolved Solids (TDS) This is a measure of...Read More

Ward Laboratories has been performing stalk nitrate testing since 1990. This test can be utilized to evaluate the efficiency of your in-season nitrogen program for corn and sorghum. A stalk nitrate analysis is to be used only for agronomic management. When evaluating nitrogen use efficiency, we specifically check a lower portion of the stalk for...Read More

Recently, I have consulted with packgoat hobbyist and livestock producers to interpret their livestock water suitability report. Because water is a vital nutrient, understanding these reports is very important to make good decisions. Water plays an important role and many biological functions including transportation of essential nutrients to body tissues and cells, lubricant for the...Read More

Utility hay is low quality hay. Typically, hay categorized as utility hay is high in fiber and low in energy and protein. Upon visual inspection, poor quality hay often contains seed pods, if it is a legume species, or seed heads if it is a grass species. Utility hay is hay that has been harvested...Read More

Acute nitrate toxicity occurs when animals consume high-nitrate forages for a short period of time. Nitrate is converted to nitrite by rumen microbes as an intermediate step in converting the nitrate to microbial protein. Ruminant animals are specifically at risk, as they bring up the feed bolus for chewing and inhale the nitrite. The nitrite...Read More

BMR forages include sorghums, millets, sudans, corn and hybrid variations such as sudex. BMR stands for brown midrib, the visible phenotype associated with the low-lignin genetic mutation. These forage varieties claim to improve animal performance when fed ad libitum. Improved digestibility increases the rumen passage rate. A rapid passage rate results in less time spent...Read More

Brown mid-rib forage (BMR) varieties have been around since the early 2000s. Yet, I still find producers aren’t sure about what BMR means to their operation. Traits associated with BMR varieties can impact forage quality and animal performance. First, lets define what BMR really is. Then, we can examine how this trait impacts forage quality...Read More

Here at Ward Laboratories, INC. we have recently updated our fee schedule and website. One major change in the fee schedule is that we are asking clients to call and visit with our Professional Animal Scientist prior to sending samples to be analyzed for Prussic Acid in livestock feed. We have heard some of the...Read More

Even before the ‘bomb cyclone’ hit, it was a heartbreaking spring for livestock producers. I was receiving phone calls of late term abortions and lost calves and cows due to poor nutrition. Before these historic floods, Nebraska and surrounding states were already enduring unusually low temperatures and heavy snow fall. Producers were struggling with guidelines...Read More

Often when a producer is determining the cause of an abortion storm, they look to the feed as a potential cause. While feed can potentially contain toxins which cause abortion, working with your veterinarian is key in determining the cause of an abortion. Toxins in the Feed Nitrates are often the first thoughts when an...Read More

I have received several phone calls from producers with concerns about toxic plants or noxious weeds in hay. Most of the time grazing animals avoid these toxic plants, and prefer to as weeds are typically unpalatable. However, when the animal is consuming hay or a mixed ration contaminated by these toxic plants, it is difficult...Read More

Last Saturday I spent the day in a classroom at the US Meat Animal Research Center learning about sheep production and tools put out by University of Wyoming Extension to help producers make the best possible management decisions. The meeting was a cooperation between the University of Wyoming Extension, Great Plains Veterinary Educational Center, Nebraska...Read More

Every once in awhile I get asked if soybean plants or stubble should be tested for nitrates.  Soybeans are legumes like alfalfa, and like alfalfa, under stressed conditions can accumulate a toxic concentration of nitrates.  Soybeans are listed as nitrate accumulators by the Iowa Beef Canter.  Therefore, if you are having doubts, send a sample...Read More

We’ve all heard the Luke Bryan song “Rain is a Good Thing”. While it may be a catchy lyric, lack of rain can cause livestock producers to suffer from drought and heat stress issues, while too much rain can leave farmers dealing with flood damage.  This year has been especially testing from those aspects.  The...Read More

The highlights of this year’s KSU Cattlemen’s Day were the tour of the Feed Intake Measurement Facility given by Dr. Bob Weaber and the necropsy demonstration given by DVM A.J. Tarpoff.  The take away I want to reiterate to any livestock producers is that a post-mortem exam is crucial in determining the cause of death...Read More

The state of Nebraska is in the center of the High Plains Region of the United States.  The states that make up this region are Nebraska, Kansas, Colorado, Wyoming, and the Dakotas.  I checked the current drought monitor and found that southern Nebraska and southern Wyoming are abnormally dry, and Kansas, Colorado and the Dakotas...Read More

Typically, livestock water access and quality are considered during the summer months when heat stress is a concern.  I am choosing to address this topic during the cold winter months because as the temperature drops, below the thermal neutral zone animals consume more feed to increase metabolic heat production and water intake requirements increase with...Read More
