In About the Abstract, the experts discuss a study by Cordial and Carrie (2024) in the Journal of Animal Science, which compared the impact of metaphylaxis with Tulathromycin versus saline on high-risk beef stocker calves over 42 days. The study found that calves treated with Tulathromycin had higher average daily gain, especially in the first 14 days, and fewer treatments for respiratory disease. Culture results showed more bacteria in saline-treated calves at follow-up. Antimicrobial use was higher in the Tulathromycin group, but the number of regimens was similar. The study suggests that metaphylaxis may improve health and performance while managing antimicrobial resistance.
In this episode of BCI Cattle Chat, guest Dr. Cassandra Olds continues the discussion of Theileria, a tick- and fly-borne parasite affecting U.S. cattle herds. The team explains how it spreads from the East Coast westward, causes anemia-like symptoms, and persists for life in infected animals. They stress prevention through stress reduction, parasite control, and good nutrition, noting that no approved treatment exists. The conversation shifts to preparing heifers for breeding season, emphasizing pre-breeding exams, tracking weight and reproductive readiness, and managing nutrition to ensure early conception and lifelong productivity.
In this Tox Talk episode, Dr. Brad White and Dr. Scott Fritz review a case involving six dead calves out of 38 fall-calving cow–calf pairs on pasture. The producer had not been checking the herd frequently, making the exact timeline of deaths unclear. With at least one calf estimated to have been dead for 4–5 days. They emphasize how decomposition, weather, and time since death affect necropsy value. Initial differential diagnoses focus on infectious causes and potential toxicities, given that only calves were affected.
This episode of Cattle Chat features guest Dr. Cassandra Olds, an entomologist, who shares with the group about her research on Theileria, an emerging protozoan parasite in cattle. Dr. Olds explains that Theileria is tick‑borne but can also be spread by sucking lice, possibly stable flies, limited placental transmission, and contaminated needles or equipment, emphasizing single‑needle use and the difficulty of vector control. The conversation then shifts to winter hay feeding strategy: estimating cow weights and forage intake, testing hay quality, minimizing waste, cleaning up old hay to reduce stable fly breeding sites, and tracking bale disappearance over time to adjust feeding and prevent cows from losing condition.

On Cattle Chat this week, Dr. Bob Larson, representing the Academy of Veterinary Consultants (AVC), and guest Dr. Fred Gingrich, with the American Association of Bovine Practitioners (AABP), discuss the work their organizations are doing. Anaplasmosis is also discussed, highlighting its transmission by ticks, the limitations of current control methods, and the importance of early veterinary intervention to manage the disease.
Brad White and Dr. Bob Larson discuss a case where a client found an aborted fetus in their herd. Dr. Larson suggests identifying the aborting animal, collecting samples from the fetus, including the placenta, lung, liver, and brain, and holding them for further analysis. He emphasizes the importance of understanding the herd’s history, including the age and origin of the cows, and potential causes like Neospora, IVR, BVD, and feed contamination.
In this week’s episode of Cattle Chat, the experts discuss the evolution in the feedlot industry. They debate how producers used to calculate cost based on feed efficiency. The team also questions different cow-calf practices. Lastly, they debate whether or not you should have bigger cows with heavier weaned weight for your calves or if you should have smaller cows so there are more cows per acre, resulting in more calves being sold. Â

Weaning and preconditioning calves is a stressful time for the calves, but a time when a lot of value can be gained with the right management. Preconditioning can allow calves to get over the stress of weaning, become bunk broke, and gain some weight all of which adds value to the calves at the time of sale. Calves that are weaned often spend a considerable amount of time walking the fenceline bawling, and more importantly not eating. During this time calves can lose weight, which means that for preconditioning to be cost effective, the calves must regain the lost weight and gain additional weight.
A recent study evaluated 3 different weaning methods and 3 different forage sources on preconditioning weight gain. Calves were weaned abruptly, fence-line weaned, or nose-flap weaned. Within each weaning method, calves were fed cool-season grass-clover baleage, bermudagrass hay, or grazed a pasture with a mixture of crabgrass, pearl millet and forage soybean for 60 days. The crude protein of the baleage, hay, and pasture were 14.9, 12.8, and 10.6%, and the estimated total digestible nutrients of all forage sources was approximately 55%. All calves were fed dried distillers grains at 1% of body weight.
There was no interaction between weaning method and preconditioning diet. Calves weaned using the fence-line method gained 1.85 lb/day compared with 1.76 lb/day for the nose-flap and abrupt weaning methods during the first 30 days. There was no difference in weight gain among weaning methods for the second 30 days or overall.
Calves fed hay gained faster in the first 30 days of the preconditioning period, but much slower in the second 30 days than calves fed baleage or pasture (Figure 1). There was no difference in gain between baleage and pasture groups in the first or second 30 days. Over the entire 60 days, calves fed hay gained less than calves fed baleage or pasture.
Weaning method and forage source can affect weight gain in the first 30 days, but more important economically is the weight gain of the overall preconditioning period. In this case, weaning treatment did not affect overall weight gain, but forage source did.
