In the most simplistic terms, the body (humans and animals) could be compared to a medium in which millions of chemical reactions take place with the support of food energy. These reactions are the basis of life without which life will cease to exist. The body can simply be called the “fire of life” because oxygen is one of the main substances required by humans and animals to maintain this fire. This fire can neither be allowed to burn out of control nor be extinguished...

Key mechanisms of action of a blend of plant extracts within the ruminants microbial systems. The results of several trials and published researches coming from every part of the world have recently brought to light new modes of action that explain the reasons why tannins foster an improvement in both animal welfare and performance, going deeper than the traditionally recognised ruminal protein by-pass mode of...

Introduction The work of Dr. Mike Allen, Michigan State in the late 80’s, measuring NDF digestibility of different corn silage hybrids, initially resulted in much controversy. There was much resistance to the concept that differences in fiber digestibility in corn silage could have an impact on animal performance. He proceeded to do studies with BMR hybrids as well as with conventional hybrids both in lactating cow studies as well as a demonstration of a wide range...

Today, due to rising feed costs, one of the key objectives for farmers is to optimize the value of the diet. The cornerstone of ruminant health and performance is the rumen, where forage and feed are converted into energy (volatile fatty acids, VFAs) and microbial protein thanks to the activity of the rumen microflora: bacteria, protozoa and fungi. The rumen microflora is responsible for fiber degradation, and the extent and efficiency of the process relies on various factors and determines...

In the current context of the international dairy market, increasing milk production regarding quantity is no longer relevant due to low prices. Now more than ever, producing more milk fat and protein is a proven way to enhance herd profitability. The best way to boost milk fat and protein is to promote rumen fermentation with a particular focus on fiber digestion. ...

For many years dietary protein binding has been considered the main property of tannins within animal nutrition, but more recent speculations have highlighted many other mechanisms of action for tannins. Antispasmodic effect on gastrointestinal passage, reduction of rumen starch degradation, local immune response modulation and antioxidant effect are some known examples, but perhaps the most important mechanism that explains the role of tannins, their strong and lasting impact on...

Many dairy herds will see milk butterfat levels drop when their herd is grazing lush, spring grass – something that is often accompanied by dungs becoming loose.
But back in 2016, dairy farmer, Tim Fitzgerald, not only noticed loose dung and reduced butterfats in his...

Making the most of grazed grass is critical for any profitable dairy enterprise. When weather conditions allow, farmers will already be trying to get cows out grazing by day and will get their herds out full time as soon as weather and ground conditions, as well as grass supply, allow.

INTRODUCTION Rumen microbes ferment dietary carbohydrates and protein to obtain ATP, which in turn is the major source of energy required for microbial growth. The two major reactions of rumen fermentation are volatile fatty acids (VFA) and microbial cells; the former are a primary source of metabolizable energy and the latter the primary source of metabolizable amino acids for maintenance and milk synthesis. The efficiency with which dietary nutrients are converted to energy...

Introduction Accurate predictions of nutrient supply and nutrient requirements are essential to modern ration formulations and animal production. Accurate and precise models allow provision of nutrients to meet requirements for maintenance and optimal production without supplying excess nutrients that contribute to inefficiency or environmental damage. Most nutrient models predict...

Over the past 30 years, the concept of establishing requirements and evaluating nutritional adequacy by use of nutritional models for dairy cattle has taken over the feed industry. Private companies, universities, feed companies, governments and even individual nutritionists have developed models. It will be the purpose of this paper to look at some concepts governing nutritional modeling, recommend some techniques for evaluating a model, and look at a few...

Take Home Messages By-product feeds can provide nutritional and economic benefits for dairy managers. Pricing and positioning are key focus areas to consider. Several questions must be managed for on-farm success. Feed variation must be considered when building dairy rations using by-product feeds. ...
