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.
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.
UNIVERSITY PARK, PA – The Penn State Extension Dairy Team has just released their third mobile app; CropCents. The new mobile app calculates the cost of all home raised feeds by including direct and indirect costs. This app can be used by crop, dairy, and beef producers.
DairyCents Pro producer and consultant versions of the mobile app are now available for both platforms - Android and iPhone
Careful planning keeps milk production high when the Penn State Dairy transitions to new corn silage.
Preliminary research from Purdue found that on average, farms could spend an additional $7.50 for polled genetics and break even with the average costs of dehorning.
