Effects of foliar-applied ethylene inhibitor and synthetic cytokinin on creeping bentgrass to enhance heat tolerance
Heat stress is a major factor causing leaf senescence and other physiological damages in cool-season grass species. Cytokinins and ethylene are two major plant hormones affecting leaf senescence. The objective of this study was to determine whether foliar application of an ethylene synthesis inhibitor (aminoethoxyvinylglycine, AVG) and a synthetic cytokinin (trans-zeatin riboside, t-ZR) would ...

Optimizing dosages of seaweed extract-based cytokinins and zeatin riboside for improving creeping bentgrass heat tolerance
Seaweed (Ascophyllum nodosum Jol.) extract-based cytokinins (SWEC) have been used to improve turfgrass stress tolerance, but optimum dosages for improving creeping bentgrass (Agrostis stolonifera L.) heat tolerance are lacking. This study was designed to examine effects of SWEC at various dosages on creeping bentgrass heat tolerance and to compare their effects to a trans-zeatin riboside ...

Summer Strategies to Reduce Whole-Herd Heat Stress
Summer is just around the corner and with it, heat stress. According to a 2019 Foundation for Food and Agriculture Research study, the US dairy industry experiences $1.5 billion in losses annually to heat stress. Higher temperatures can affect herds, and in turn, can decrease performance, production, and profit. However, heat stress impacts more than just the milking herd. Between calves, dry ...

Three Tips to Reduce Heat Stress in Dairy Cows
Summer is here and with it comes high temperatures, high humidity, and increased chances of heat stress. According to a 2019 Foundation for Food and Agriculture Research study, the US dairy industry experiences $1.5 billion in losses to heat stress annually. With afternoon humidities of 60-70%, and temperatures at 75-77°F, cows may already begin to experience the effects of heat stress ...

The Long-Term Ramifications of Heat Stress on Dry Cows
At VES, there are few aspects of cow care that fester in our craw more than ignoring the impacts of heat stress on dry cows. It’s a critical period in a cow’s lactation cycle that deserves every ounce of care and attention as all others and can have long-term implications on a herd if ignored. Dry Cow (n.) – A late gestation, non-lactating cow. Often considered an afterthought ...

Water: A Key Element for Cow Cooling from The Inside-Out
When thinking about achieving cow comfort, our focus at VES revolves around the engineering, design, and layout of fans, lighting, soaking technology, and high-pressure fogging within a barn. Those elements comprise the core of what we do, but it’s not everything. Consider this: 88 percent of milk consists of water, so ensuring plenty of fresh drinking water is available to cows at all ...

Seasonal infertility: the cause, the cost and can you prevent it from happening?
Still summer and already warning for the upcoming seasonal infertility?! A good understanding of what causes seasonal infertility or the so-called after-summer dip can help in preventing and limiting the negative consequences. What is seasonal infertility? It is the natural phenomenon occurring in September and October when healthy sows spontaneously return to service about 4 weeks after ...

White wheat grain quality changes with genotype, nitrogen fertilization, and water stress
The production of hard white winter (HWW) wheats (Triticum aestivum L.) with acceptable protein content and quality over different environments requires the correct combination of genotypes and management practices. The objectives of this study were to evaluate moisture deficit and N management on grain protein and quality of seven HWW and two soft white winter (SWW) genotypes, and to identify ...

Planning a Successful Ventilation Retrofit
In a perfect world, every barn would be a new build where ventilation could be entered into the formula throughout the design, engineering, and building process. That fantasy, as you may have guessed, sure isn’t what we at VES work with on a day-in-day-out basis. The reality is that a large swath of the ventilation consultations and installations we do at VES are actually retrofits ...

A higher birthweight due to preventive actions!
The majority of pig breeders knows the yearly production cycle. A productive first half of the year turning into a period with possible heat stress followed by seasonal infertility in September to end with less viable piglets in October and November. Breaking this cycle completely is impossible due to the fact that some of the causes are deeply wired into the genetic code of the pig. Although, ...

Swine Production Tips and Feeding Strategies to Dodge Temperature Variations : Beating the Heat in Farrowing!
The effects of heat stress on lactating sows has been studied by several research institutions worldwide. We can look at primiparous (first parity) or multi-parous sows but the results are similar (Williams, 2009) For this discussion, let us look at farrowing room environment conditions of 68°F (desired) vs. 77°F (hot). The period that should be most scrutinized is the ambient ...

Chicago Council lists three-decade changes in greenhouse gases and average temperature
In 2011, we wrote a column, “Global warming is happening: How should farmers respond?” (http://agpolicy.org/weekcol/549.html). In that column we began by saying, “There was a time when one could legitimately argue that there was a lack of scientific agreement over the issue of the role of humans in global warming and even whether we were in a cooling or warming period. It is ...
