Dr. Brad White and Dr. Bob Larson are back to discuss a case where a producer had 20% of heifers open. They explore potential causes behind this reproductive issue, from bull problems to nutritional and health-related factors. They also share practical strategies and management tips producers can implement to improve reproductive success and set the herd up for a better breeding season.

In this episode of Bovine Science Dr. Matt Miesner is back to discuss calf scours. Dr Miesner brings some tips on rehydrating calves, the options available, and how long you should give the calf electrolytes. They also discuss resources that are available to assist in making decisions.

This week on After the Abstract, Dr. Brian Lubbers and Dr. Brad White break down a cutting-edge study that explores how technology can help detect bovine respiratory disease (BRD) earlier in pre-weaned dairy calves. The study tested automated monitoring systems that track calves’ feeding patterns, movement, and social interactions. The goal? To see if behavioral changes could serve as early warning signs for BRD—before clinical signs appear.

In this episode of Bovine Science, we delve into the intricacies of sorghum silage processing and its impact on beef heifer nutrition. Our discussion centers around the recent study published in the Journal of Animal Science titled “Evaluation of kernel processing and processor type in whole-plant sorghum silage: effects on nutrient digestibility and animal performance in backgrounding beef heifers” (https://doi.org/10.1093/jas/skae369).

Introducing the newest edition of Bovine Science, Pasture Pulse. For this edition Dr. Brad White is joined by Dr. Matt Miesner to discuss cattle health cases. On this episode a cow appears sick shortly after having the calf, but the cause is not easy to identify. Thanks for listening.

When this producer goes to move his heifers he finds one dead and others ill. With no obvious clues, what caused the heifer to die and could this happen to the others? Find out on this episode of Tox Talk a Bovine Science Podcast with Dr. Brad White and Dr. Scott Fritz? Thanks for tuning in and enjoy the show!

The toxicology website and Bovine Sciences with BCI podcasts have been sponsored in part through a veterinary services grant that Dr. Scott Fritz, Dr. Steve Ensley and Dr. Bob Larson have received to share more toxicology information and examples for people to understand what to submit and how to submit. Another part of that grant has been working with people and producer in the field.

On this episode of After the Abstract Dr. Brian Lubbers brings in a hefty research paper which aims to compare nasal microbiome community diversity and composition. Drs. Lubbers and White discuss the implications of these findings, considering how nasal microbiome profiling could enhance BRD diagnostics and inform targeted interventions. Thanks for listening!

In this episode our hosts discuss the affects of pregnancy on digestion in beef cattle. They look at passage rate and extent of digestibility. Dr. Lancaster brings and article out of Brazil that studies these aspects.

On this episode of Bovine Science Dr. Bob Larson brings a case study where a producer had only their purebred cattle open and not crossbred. Dr. Larson and Dr. Brad White will go through how they got to the bottom of this case. They will also look at what the producer can do to keep from having this problem again.

Four dead calves found in a pasture after being turned out for the spring. What caused it, and why were no cows affected? Find out on this episode of Tox Talk a Bovine Science Podcast with Dr. Brad White and Dr. Scott Fritz? Thanks for tuning in and enjoy the show!
