Although excessive inflammation is bad, the results of a University of Guelph study revealed why some inflammation at calving is positive. The key is discovering the balance between healthy and excessive inflammation, according to Barry J. Bradford, PhD. Inflammation is needed to drive the birthing process, and we also think it’s important for aiding in the metabolic … [Read more...]
Paired housing in lieu of group housing
Group housing for dairy calves is not an easy system for all farms to implement. Dairies can still reap the benefits that come from raising calves in social groups by housing two calves together as a pair. I really like pair housing because we get a lot of the advantages of social housing without the detrimental effects of large groups. There is a lot of opportunity to modify … [Read more...]
Scouring calves still need milk
Calves must maintain adequate fluid and nutrient consumption while dealing with diarrhea. Jesse Goff, DVM, reminded producers, “If you withhold milk from the calf, the calf starves.

Dry cows need shade to thrive, increase lifetime production
When talking about environmental impact in dairies, most would think about carbon footprint or water quality. However, a University of Florida study determined it is most ideal to cool dry cows during the entire dry period to prevent milk loss. The same should be provided for bred heifers. Researchers found reduced dry matter intakes pre-calving and weaker immunity pre- and … [Read more...]
Target these goals for dairy steers
Dairy and crossbred steers are no longer thought of as subquality meat. However, there are some nuances to ensure quality.

Could artificial insemination become illegal?
Artificial breeding might become illegal should a ballot initiative in Colorado be enacted by the state’s citizens says Corey Geiger.

Cows aren’t to blame for most mastitis
Considering all factors that contribute to mastitis risk, cow factors only account for 20 percent of cases. The other 80 percent of infections are caused by humans, and more specifically, how the farm is managed. About 100 organisms can cause infections in the udders of dairy cows. When we have mastitis issues, we can’t really blame the cow. We have to look at ourselves … [Read more...]
Are farmers teaching cows bad habits?
It could be that slug feeding methods are forcing dairy cattle to eat too much too quickly causing a negative impact on the rumen environment. Management plays a role in feed bunk behavior, as farmers don’t have to just think about what feed animals consume, but also the manner in which they eat it.

Overtime pay for dairies is closer than you think
Dairy farming is not a 40-hour per week job, but with labor laws becoming more restrictive, employers may have to treat it as such.

Resiliency trumps size on smaller dairies
Sometimes bigger is not better. That is one conclusion that can be drawn from a recent University of Minnesota study of small- to medium-sized dairies. The study data set combined animal health, production and farm financial data to help dairy farms create more financially sustainable operations. Financial resiliency was defined using the adjusted net farm income ratio. … [Read more...]

Don’t penny-pinch preweaning
Inherent in animal health pro relationships with dairy producers is the element of helping them manage their ROI. A.F. Kertz provides a review of research about calf inputs and concludes cutting costs in the calf period may save on a daily basis but doesn’t pay over the heifer raising time period. I think too often dairy producers focus on the calf period as a place to cut … [Read more...]
