Feed quality and nutrition

By Rick Grant, William H. Miner Agricultural Research Institute | Forage quality is an overlooked component of cow comfort. Forage particle size, NDF degradability, fragility and dietary forage percentage must allow the cow to consume feed within 3 to 5 hours per day. Too much forage fiber, poorly digested and/or coarsely chopped forage will extend eating time beyond 5 hours per day and probably limit dry matter intake (DMI).

By Erin Schwandt, Ph.D., and Paige Gott, Ph.D., dsm-firmenich | The presence of mold on grains and feed ingredients has been shown to negatively impact the nutritional value, impacting energy, vitamin and amino acid digestibility. Mold also can reduce feed palatability.

By Cody McCary and Michelle Chang-Der Bedrosian, Ph.D., | Butyric fermentations occur in silages that are wet and have a high pH, which creates the ideal growth environment for Clostridia. A low pH is our best tool to combat clostridial fermentations, and the faster the pH can decrease the better.

By Stacy Nichols, Vita Plus | As we enter the summer months, we face a higher risk of milk fat depression caused by several factors.  One of those factors can be the increased availability of starch and corn oil in well-fermented corn silage and high moisture corn.

By Michelle Chang-Der Bedrosian, Ph.D., Vita Plus | The initial phase of making silage is the aerobic phase and it is characterized by the presence of oxygen.  The aerobic phase begins when the plant is cut in the field and continues until the silo is sealed (either the plastic is laid on top of the silo or the bag silo is sealed) and oxygen is consumed by the upfront fermentation. 

By Luke Daninger, Ag Partners Coop | As we approach warmer temperatures and alfalfa greens up throughout the countryside, it is good to think about a key factor in alfalfa production: minimizing ash content during harvest. Main concerns of high ash content in forage include the fact that it has no energy value and that elevated soil contamination could potentially result in Clostidria being found in the silage.

One strategy to control costs on your dairy is to retain of much of your homegrown forages - and the nutrients they contain - as possible.  Choosing the right inoculant and oxygen barrier plastic will help you limit dry matter (DM) loss and spoilage.  

By Luiz Ferraretto, Ph.D., University of Wisconsin-Madison | Forage needs vary vastly within and among dairies across years.  Implementation of practices targeting greater yields is key; however, finding the sweet spot between yield and nutritive value is no simple task, especially when producing silage with high fiber digestibility.

By Jon Rasmussen, Vita Plus | While farms may “break the rules” of forage storage every now and then, the goal should always be to SAFELY store forages with nearly zero oxygen exposure.  If you find yourself frequently breaking the rules, it might be time to resize your feed pad.  Following are four rules to help you in the planning process.

By Kassidy Buse, University of Nebraska | The quality and characteristics of forages can have direct impact on milk production and profits.  We typically focus on characteristics such as starch content, protein content and NDF digestibility as we include forages in rations.  But as the attributes of fiber and its fractions have continued to be explored, forage fragility has emerged as an area of interest.

By Renato Schmidt, Ph.D., Lallemand Animal Nutrition | Quality forage inoculants can be used to control the fermentation and quality of forages, as well as enhance the overall value at feedout. A newly available inoculant offers flexibility in feedout by allowing a silage to be fed as soon as 15 days post-ensiling.

By Dr. Zach Sawall | We often focus on growing crops to maximize tonnage, and we figure out how to deal with that feed once it’s in the bunk. A more economical approach is to look at what the cow needs and focus on growing forage to meet those needs.

A long fall allowed for great harvest conditions across most of the upper Midwest.  Vita Plus consultants across the region recap the 2022 harvest.

By Cody McCary, Vita Plus forage specialist | The stage of plant growth and timing of harvest are essential to achieving the yield and quality goals for a given grass crop. The progression from one stage of maturity to the next often happens rapidly. To combat a narrow harvest window, consistent monitoring of in-field conditions and plant stage of maturity is necessary.

Steve Murty, Vita Plus – Delayed planting, volatile grain markets and high feed costs are once again dominating agricultural headlines, reminding farms to double down on forage management practices to preserve homegrown protein yields and save out-of-pocket expenses.

Dr. David Weakly, Forage Genetics International – One of the major factors negatively impacting harvested alfalfa forage quality is leaf loss. That’s because leaves have an RFQ of about 550 while stems have an RFQ of 70 to 80. A new equation predicts the percent of leaves in alfalfa from NDF, protein and NDFd28 measured in the sample.
