- Copper Sulfate Hoof Baths and Copper Toxicity in Soil
- On most dairies spent hoof baths are dumped into the manure pit or lagoon so the copper ultimately gets spread on production ground with the manure. Recently there have been several reports in the dairy press regarding copper accumulation in soils from this practice.
- Cost and Other Risks Associated with Natural Service Sires
- Based upon a survey of Pennsylvania dairy producers, the major reasons listed by those who do not use artificial insemination for their heifers are the perception of lowered conception rates with artificial insemination (AI), difficulty or time involved with estrous detection, location of heifers was inconvenient for reproductive management and lack of restraint facilities.
- Costs and Risks Associated with Natural Service Sires
- In light of the recent tragic death of a Pennsylvania dairy producer by a herd bull I feel it is important to review once again the costs and risks of having a bull on the premises.

- Dairy Needs to Make a Decision Soon: Air Emissions Consent Agreement
- The current air quality related issues making news are not about odor. This is a whole new arena, which involves how much ammonia, hydrogen sulfide, and particulate matter is being emitted from an animal facility. Citizen groups are saying that animal agriculture was not exempt from the 1997 Clean Air Act and EPA should be enforcing these regulations against AFOs (Animal Feeding Operations). Technically, EPA could go back starting in 1997 and fine an operation that exceeded air quality parameters or did not apply for appropriate permits.

- Dehydration in Dairy Calves
- Evaluating and monitoring dehydration in your dairy calves is an important task for the dairy calf manager.
- Develop a Plan to Minimize the Adverse Affect of Heat Stress on Reproduction
- Even in Pennsylvania, periods of high temperature decrease reproductive performance. It is real! Dairy cows are at risk of becoming heat stressed more than most animals because with genetic selection for milk yield the cow has a high internal heat production. This has presented the dairy producer with a constant challenge to maintain high production and good reproductive performance during the summer. In lactating cows, the critical limit when hyperthermia occurs is approximately 78 degrees.
