Effect of an injectable trace mineral at the initiation of a 14 day CIDR protocol on heifer performance and reproduction.

In the spirit of this week’s Bill E. Kunkle Interdisciplinary Beef Symposium update, let’s review a new TAS article that evaluates heifer reproductive performance when given an injectable trace mineral, paired with the 14 day CIDR estrous synchronization protocol.

In vivo measures of mammary development in gestating gilts.

Learn about alternative measurements of mammary development in gestating gilts in this issue Journal of Animal Science.

Validation of transrectal ultrasonography for assessment of corpora lutea characteristics in pregnant sows and its relationship with litter characteristics at birth.

Learn about using transrectal ultrasonography in pregnant sows for assessment of corpora lutea in this issue of Translational Animal Science.

Effect of forage species and supplement type on rumen kinetics and serum metabolites in growing beef heifers grazing winter forage.

Learn about feeding alternative forage species and supplement types on growing beef heifers.

Economic impacts of lameness in feedlot cattle.

Learn about the economic impacts of lameness in feedlot cattle.

Dietary supplement rich in fiber fed to late gestating sows during transition reduces rate of stillborn piglets.

In a December 2017 study published in the Journal of Animal Science, researchers investigated how dietary fiber (DF) supplemented feed affected sow reproductive performance. It was hypothesized that DF supplementation starting from two weeks before farrowing (including transition) would reduce piglet mortality.

Review: Effects of Ractopamine Hydrochloride (Paylean) on welfare indicators for market weight pigs.

Read more about the December 2017, Translational Animal Science published review article that summarized the effects of various dosages of Ractopamine Hydrochloride on market weight pig welfare.

Intraruminal infusion of oligofructose alters ruminal microbiota and induces acute laminitis in sheep.

In a December 2017 article published in the Journal of Animal Science, researchers induced acute laminitis in sheep with oligofructose. Read this interpretive summary for more information.

Porcine Reproductive and Respiratory Syndrome virus reduces feed efficiency, digestibility, and lean tissue accretion in grow-finish pigs.

In a recent study published in the December 2017 issue of Translational Animal Science, a research team at Iowa State University has concluded that Porcine Reproductive & Respiratory Syndrome (PRRS) virus reduces feed efficiency in grow-finish pigs.

Effect of castration method and analgesia on inflammation, behavior, growth performance, and carcass traits in feedlot cattle.

In February 2018, Journal of Animal Science published an article that investigated the effect of castration timing, method, and analgesia use on feedlot cattle behavior, physiology, and performance.

Utilization of canola and sunflower meals as replacements for soybean meal in a corn silage-based stocker system.

In December 2018, Translational Animal Science published an article that investigated the effect of using an alternative protein source in stocker diets.

Responses of pregnant ewes and young lambs to ovalbumin immunization, antiovalbumin antibody transfer to lambs, and temporal changes in antiovalbumin antibody.

A recent study published in Translational Animal Science in December 2017, researchers investigated immunity in lambs by measuring anti-ovalbumin antibody (OV-IgG).

Cultured equine satellite cells as a model system to assess leucine stimulated protein synthesis in horse muscle.

A research team at the University of Minnesota has found that the amino acid leucine activates the mTOR translation initiation pathway and increases transcription of global proteins in cultured equine satellite cells.

Effect of ruminal acidosis and short-term low feed intake on indicators of gastrointestinal barrier function in Holstein steers.

A recent study published in the Journal of Animal Science in February 2018, researchers looked at the effects of low feed intake and rumen acidosis on gastrointestinal tract barrier of Holstein steers. 

Risk factors associated with animal mortality in pasture-based, seasonal-calving dairy and beef herds.

In January 2018, Journal of Animal Science published an article that investigated the risk factors associated with animal mortality in pasture-based, seasonal-calving dairy and beef herds.


Part I: Brand influences steak palatability ratings

In today’s society, many consumer purchasing decisions are brand-driven. Beef is no different.

Part II: Brand influences ground beef palatability ratings

When consumers are aware of ground beef brand and fat concentrations, it greatly influences how they rate their eating experience.

Lighting type affects ground beef color

Research published in the October 2016 issue of the Journal of Animal Science examines the effect of retail display lighting on ground beef color.

Methane matters

Growing concerns posed by climate change have fueled animal science research into reducing methane emissions from livestock.

New interpretive summary from July (2016) Animal Frontiers

It is important to understand how the microbiota play a role in digestion so that we can better understand how to achieve efficient weight gain in livestock.

Oral stomach tubing effectively collects ruminal dissolved hydrogen

Oral stomach tubing may be a feasible method to collect ruminal dissolved hydrogen in intact animals.

Heat stress affects pig's digestive and absorptive capacity

The metabolism of some amino acids is modified in pigs to counteract the negative effects of heat stress.

New JAS interpretive summary

Researchers have observed that differences in beef juiciness, tenderness, and flavor were dependent on dark cutting severity.

Identifying “Super Momma” Cows

Researchers have found that if a cow produces and transfers increased amounts of immunoglobulins into her colostrum she is likely to do so again and again – giving calves that receive colostrum from “super moms” the best chance for a healthy start.

Researchers discover methane traits are heritable in beef cattle

For the first time ever, researchers in Australia have discovered that methane emissions from beef cattle are a heritable trait.

No difference in meat from rabbits fed GM soybean meal

A study from researchers in Italy adds to a growing body of research that shows meat from animals fed genetically modified plant material is no different than meat from animals fed a conventional diet.
