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.
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.
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.
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.
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.
The Penn State Dairy Herd makes valuable improvements over past 12 years due to excellent team work.
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. The demand for a safe, high quality product is driven, in part, by consumers who put pressure on producers for transparency and adherence to safety standards. Processors also require a product that consistently meets their standards resulting in the production of a high quality, uniform product on a regular basis. Producers in turn, may be rewarded with premiums for meeting quality standards. But do these inspections correlate with the quality of milk that is being shipped?
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.
Corn silage quality changes more than the weather at the Penn State Dairy Farm.
The Penn State dairy herd feeds sorghum-sudan silage for the first time with success.
Maintaining energy requirements through the cold winter keeps the Penn State Dairy Herd milking consistently to take advantage of almost a $30 milk price.
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.
The fresh cows increases milk production by ten pounds due to diversity of energy sources and the amounts altered to complement the forage quality.
Changes in forages result in pleasant component increases.
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.
