It was good advice then, and it still rings true. An adventure in cleaning out old file cabinets yields record keeping advice that has stood the test of time.
Fall is almost here and with that will come corn silage harvest. One common side effect of silage making is silage effluent. No matter our best efforts to harvest at the correct moisture and in a timely fashion, it happens. If you have a silo, upright or horizontal, you have some amount of silage effluent.
Synchronization protocols have become a great tool for many breeding programs, but most would probably abandon them in a heartbeat if there was another effective way to consistently predict ovulation and pinpoint the perfect time to breed cows. Activity monitors may provide a solution.
Several microbiological parameters are used to screen for the overall quality of milk. These analyses are associated with milk quality. They also can provide direction for trouble-shooting sanitation and procedural issues on the farm.
As tie stall dairy producers think about herd expansion they often consider converting their existing building into a milking center. In many cases this is a reasonable idea. However, ‘low-cost’ should not be interpreted as ‘cheap.’
Scientists from around the globe presented the results of their most recent research at the joint annual meeting of the American Dairy Science Association and the American Society of Animal Science last month in Kansas City, Missouri. This article highlights some of the latest findings related to feeding and managing dairy calves.
The goal of monitoring dry matter intake is getting to know your cows. This is extremely important for understanding what is normal and what is abnormal for the operation. It can also help explain how the cows may be responding to forage quality changes, ration changes, or labor’s implementation of the feeding program.
What is the difference between a barn built in 2014 and one built in 2002? It is likely there are multiple opportunities to upgrade an older barn and improve cow comfort.
Inspections are an inevitable part of the routine on most dairy farms.
Water makes up 87% of the milk given by a cow, and drinking water satisfies 80 to 90% of a cow’s total water needs. Consider how and when cows drink to create a watering system that ensures every cow gets as much water as she will drink.
A 2013 study suggested that US EPA estimates of methane production underestimated true emissions. Penn State scientists collaborated with other experts to examine that claim. Using a method of calculating emissions based on feed consumption, these researchers concluded that the EPA estimates are accurate.
Most of the time when we think about sorting and dairy cows, we focus on the negative consequences of cows selectively eating the finer particles in a diet. But there is growing evidence that cows facing an acidosis challenge will select feeds with high ruminal buffering capacity if given the opportunity.
When it comes to risk management it seems like things are never simple. The new approach in the farm bill appears complicated. However, farms that have developed cash flow plans on their own or with the Extension Dairy Team, already have the tools available to implement the program effectively.
Designed, installed, and operated properly, tunnel ventilation systems can play a major role in keeping cows comfortable and productive during hot weather. Providing enough fan capacity is important, but properly sized inlets – located to supply uniform distribution throughout the animal space – are essential to provide a more comfortable space for the cows.
Successful culling strategies are based on economics and utilize accurate production data. This article discusses metrics that incorporate information from a current test day and for the current lactation.
As group housing systems for calves have gained popularity in recent years, interest in acidified milk systems has also been renewed. This article describes reasons for acidifying milk or milk replacer and examines research on acidified milk feeding systems.
Consistency is one of the biggest goals when feeding calves. Whatever the liquid feed (milk or milk replacer), the temperature, total solids percentage, and nutrient level should be reasonably consistent from feeding to feeding. Large changes in any of these parameters can lead to unwillingness of calves to drink or scours in calves that do drink.
Is the dairy industry ready to move from the past 75 years of artificial insemination (AI) as the primary way of advancing genetic progress, to using genomics, ovum pick-up (OPU), and in vitro fertilization (IVF) as another combination of technologies that could be used routinely to help take the dairy industry to the “next level” of genetic progress?
Prevention of mastitis requires reducing exposure to mastitis pathogens and enhancing the ability of the heifers’ immune system to respond.
The variety of production systems make it difficult for any one farm to truly know the cost to feed its herd when basing prices solely on the prevailing market. Though analysts do a reasonable job approximating the market costs for feedstuffs like corn silage and alfalfa haylage, actual producer costs can vary greatly within the same state. For this reason, it pays to know the true costs to produce the crops fed on the dairy farm.
