Blister beetles, from the family Meloidae, are sometimes referred to as oil beetles and found in all parts of the Unites States and Canada. Adult blister beetles vary in size and color but are recognized by the elongated, narrow, cylindrical, and soft bodies. In Nebraska, the three-striped, grey, and black blister beetles (Fig. 1) are the most common species. Blister beetles produce a chemical called cantharidin which is toxic to animals and humans. The male blister beetle secretes cantharidin and presents it to the female after mating.Spanish:
Early Detection and Rapid Response (EDRR) is a concept to identify potentially invasive species prior to or just as the establishment of the invasive is taking place. An Integrated Pest Management plan (IPM) can be developed to manage, contain and eradicate the invasive species before it can spread further. This will avoid costly, long-term control efforts.
a.k.a. – Nodding thistle, Nodding Plumeless thistle
Scientific name: Carduus nutans L.
Family: Asteraceae (Sunflower family)
As we prepare for the breeding season or for those in the midst of the breeding season, it is important to think about how we can manage bull fertility and understand critical factors that can impact fertility. There are many factors that can affect sperm production; however, the main factors that can decrease sperm production are disease, fever, injury, and extreme environmental conditions. We must keep in mind that spermatogenesis, the production of sperm, is a 61-day process in bulls; therefore, it will take upwards of 60 days to have normal sperm again following an injury/insult.Spanish:
Food production is essential, and that requires beef producers to carefully consider how COVID-19 infections may impact cattle work. It is important to remember how the virus is transmitted (source: Centers for Disease Control and Prevention):Spanish:
For cattle producers who rely on wells in pastures and rangelands as a water source for their cattle, much time is spent checking water to make sure that windmills and submersible wells are delivering the water cattle need. These water checks are often made daily or every other day to ensure water is available. When problems occur with a water source cattle depend on, time is limited to get the problem fixed, haul water or move the cattle to another location where water is. Timeliness of knowing there is a problem with a well or a tank that stores water is essentialSpanish:
Basis is defined as the cash minus futures. Cash market reflects today's supply conditions and price. Futures market reflects upcoming supply and demand conditions. If it is anticipated that there will be a period of increasing supplies, futures prices will decline to reflect that information. Likewise, periods of time with expected decreasing supplies, future prices are expected to increase.Spanish:
The Central States Center for Agricultural Safety and Health (CS-CASH) at the University of Nebraska Medical Center is providing guidance on the prevention and spread of COVID-19 for farmers, ranchers and agricultural workers. Precautions include eliminating exposure, finding ways to reduce person-to-person contact, using administrative authority to establish new work guidelines as necessary, and making use of all appropriate Personal Protective Equipment.
As we approach the breeding season, cows and heifers are faced with a variety of stressors from the metabolic pressure of providing for a calf to changes in environment. Stress during early pregnancy is well documented to cause embryonic death and loss of pregnancy. However, making strategic management decisions during the fragile 2 months after breeding can help minimize those losses.Spanish:
You do not have to go far on social media to find farmers in tractors or families out with newborn calves with the hashtag “social distancing” and the caption “I’ll be engaging in social distancing this spring, like I do every year!”Spanish:
Meadows cover approximately 10% of the land area in the Nebraska Sandhills. These meadows have both subirrigated and wetland ecological sites and are an important forage resource for many ranches and provide 2 to 3 times more forage than associated Sandhills uplands. Meadows are also vital to biodiversity and hydrology in the Sandhills and there are many native wildlife and plant species that are found in these subirrigated and wetland areas.Spanish:
As livestock producers prepare for another grazing season, thoughts are often directed towards grass conditions, animal conditioning, and fence repair. An additional very important consideration should include what type of flies will impact their pastured cattle, and what method of fly control will work best for their management system. Livestock fly control should be viewed as having a positive economic impact on livestock operations. In Nebraska and elsewhere, there are three fly species that economically impact pastured cattle; horn fly, face fly and stable fly.Spanish:

Branding is the social event of the spring signaling the end of winter and the long hours of calving, and the beginning of greener pastures ahead. Friends and neighbors come from far and wide to help out and relive the cherished tradition.
As the US continues to limit the spread of COVID-19 by closing offices and promoting social distancing and working from home, agriculture does not stop. The work must go on. Although calves must be branded, not taking precautions can mean the difference between life and death for some loved ones.Spanish:
Many cow-calf producers in Nebraska have become accustomed to using distillers grains as a source of both protein and energy to help meet the nutritional needs of lactating cows from calving until green grass is available. Due to the ongoing distillers shortage, many producers are considering including corn silage in the ration to help alleviate some of the energy shortfall in their hay resources. However, concerns have been expressed that silage in the diet will result in diarrhea or scours in their calves.Spanish:
One of the ways that beef producers can be successful in their business is to identify what their competitive advantage is in relation to their competition. What is it about your product, skills, reputation, business structure, location or service that sets you apart from others? What gives you a “leg up” on the competition?Spanish:
Heifer CONSULT (Collaborative, Online, Novel, Science-based, User-friendly, Learning, Tool) is designed to help beef cow-calf producers improve the reproductive success of their heifers and young cows. If a producer is not satisfied with the current reproductive success of replacement heifers and/or first-calf heifers, this CONSULT will help identify problem areas and provide possible solutions. Please work closely with your veterinarian to create the best heifer development program for your herd.Spanish:
Best Management Practices for Livestock and Farm Operations to Stop the Spread of a Virus (like COVID-19)
While Mother Nature decided to give us a taste of spring last weekend then pull it right back, the reminder that pasture green up is just around the corner shouldn’t be ignored. One of the earliest species we see greening up is cheatgrass (also called Downy brome, Bromus tectorum). This invasive species is found throughout Nebraska but is most prevalent on rangelands in the western portion of the state. Early spring is a good time to begin planning for cheatgrass management.Spanish:
