The basic substances for building an animal's body are minerals and proteins. For the animal to move about or perform as it should it has to be supplied with energy from outside in the form of carbohydrates and fats. An over-supply of energy can be stored as a fat reserve. In the course of evolution this type of reserve has proved the most useful in animals, as fat allows the highest concentration of energy.

Global demand for animal proteins is foreseen to increase by 22% (Figure 1). Thus, one of the main challenges for 2050, in addition to meeting the high expectations in terms of food production, is facing the various issues which threaten food quality and safety, as well as land management and sustainable beef production. This will directly influence how we will raise and feed our animals to meet consumers needs. ...

The protein in alfalfa silage is subject to extensive degradation to non protein nitrogen (NPN) in the silo. Furthermore, the NPN in alfalfa silage is rapidly degraded to ammonia in the rumen and, if not captured as microbial protein, will end up largely as urea-N excreted in the urine. Milk production and milk nitrogen (N) efficiency have improving potential through amino acid balancing. Milk-N per N intake is an index for the environmental impact of the fed protein and the efficient usage...

1. Introduction. Subclinical endometritis (SCE) is one of the most important reproductive impairments in dairy cows studied in the last decade. It can be defined as the superficial inflammation of the endometrium (no deeper than the stratum spongiosum) [1] , without visible clinical signs, but significantly affecting reproductive performances [2,3] . Cytology is considered the best technique to diagnose SCE due to its feasibility...

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...

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...
