1. Rumen protects dairy cows against mycotoxins… only partially Mycotoxins are toxic metabolites, produced by fungi, that can develop in grains and forages. The most well-known and probably the most feared type of mycotoxins in dairy production are...

Wasting nutrients is a waste of money. But feed losses also have a direct effect on animal health and performance and makes the diet less sustainable. This can be prevented by giving the rumen more care and attention. In a healthy working rumen, digestion is...

INTRODUCTION The importance of nutritional management for improving production and minimizing environmental impacts from beef and dairy cattle industry is well-established (McAllister et al., 1996; Havlík et al., 2014; Bach et al., 2020). Corn grain is the most commonly used cereal grain for dairy and beef production in the United States and its high starch content yields energy to support greater levels of milk and meat production (Giuberti et al., 2014)....

Introduction Fatty liver occurs in approximately 50-60% of dairy cows at orshortly after calving2,3. It occurs because the cow mobilizes energy from adipose tissue in response to hormonal changes at calving and negative energy balance immediately after calving when the cow cannot consume enough energy to support maintenance and milk production. However, it can also occur anytime the cow experiences negative energy balance from other factors such as sickness, suboptimal...

Background Reducing the rate at which ammonia is released from urea into the rumen may allow rumen bacteria to more effectively capture the nitrogen released. Slowing the rate of release of ammonia from urea can be accomplished by encapsulating it with lipids. NitroShure Precision Release Nitrogen uses Balchem’s proprietary encapsulation technology to provide a more consistent nitrogen supply to rumen microbes, maximizing microbial protein yield, improving...

1. Introduction The use of tannin in ruminant nutrition is increasing, mainly due to its diverse positive effects in several aspects concerning physiology, metabolism, and animal performance. However, research results are quite controversial regarding the concentrations and sources used, which reinforces the need for further studies to elucidate these still evident gaps. According to Haslam and Lilley [1], tannins represent secondary compounds of plants and are present in...

Why should we do this? With a good controlled fermentation (con-trolling pH or acidity) in the rumen, we will do two things: first, we will maximize the energy derived from the fiber, starch and other carbohydrates fed and secondly we will optimize microbial protein flow from the rumen. This results in high quality protein production in the rumen and can reduce the need to feed more expensive ingredients to meet the energy and amino acid requirements of the...

INTRODUCTION Sorghum ( Sorghum bicolor (L.) Moench) is a tropical forage species widely used in ruminant nutrition. Sorghum is considered the best option in arid and semi-arid regions worldwide. Sorghum is a typical plant of hot climates due to its xerophilic characteristics, low soil fertility requirements, high tolerance/resistance to water stress and salinity (HASSAN et al., 2018). Sorghum grain has been used as an energy source in ruminant diet formulation and...

Ruminants naturally discriminate between feeds to preserve their health. They reject bitterness and sourness, but they accept salty and sweet. Do you want to know more about how cows discriminate between feeds and how palatability can improve voluntary feed intake? Listen to Sébastien Chaboche, Business Manager for Palatability in Europe and CIS, with more than 20 years of experience in ruminant nutrition....

Considering the livestock production, natural betaine plays a key role in the metabolism of monogastric animals. However, the role of betaine in ruminants and the rumen activity is underexplored until now. Therefore, AGRANA invested in a research project to study the effect of natural betaine on the rumen activity. In collaboration with the University of Veterinary Medicine, Vienna a recent study in vitro was carried out. The aim was to test natural betaine as a possible...

Increasing efficiency in the feeding systems is an important contributing factor to farm profitability. Feed efficiency is a complex function of nutrient intake in relation to growth-performance potential. Because roughly 80% of the total tract digestible organic matter intake is fermented in the rumen, an understanding of the principles of fermentation processes and the limits of the rumen function are key to optimizing feed efficiency. ...

Somatic cell count (SCC) is related to the total number of cells per millilitre of milk. Primarily, SCC is composed of leukocytes that are produced by the cow’s immune system during an inflammatory process in the mammary gland, commonly referred to as mastitis (Looper, 2012). This inflammation results from the introduction and multiplication of pathogenic microorganisms in the mammary gland, and a complex series of events leading to reduced synthetic activity, compositional changes and...

Previous studies showed that inclusion of polyphenol-rich plant extracts in feed improves performance in ruminants, but the effect may vary depending on the dosage used. It has been shown that polyphenols modify the digestive process through modulation of gastrointestinal microbiota and bypass of protein digestion. The rumen houses a highly complex microbiota which is able to convert indigestible plant mass into energy mainly through production of short-chain fatty acids...
