Welcome to the page about Additives and feedstuffs in dairy cattle nutrition of Engormix; a source of knowledge on Additives and feedstuffs in dairy cattle nutrition.
The Nature Conservancy, the Innovation Center for U.S. Dairy, and the Institute for Feed Education and Research are launching a three-year project to explore innovative feed management strategies that can reduce enteric methane emissions in dairy cattle. The U.S. Department of Agriculture (USDA) recently announced a $537,440 award for this project through its Conservation Innovation Grants On-Farm Conservation Innovation Trial program. With project partner resource contributions, the project...

Author: ballyabio Just like humans, dairy cows are also prone to a number of infectious diseases and health conditions. Timely diagnosis of diseases and effective treatment strategy is very much important for the well-being animals and significant growth of dairy business. Overall profitability of the dairy business highly depends upon how you keep cows healthy and free from diseases.

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...

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...

As this is written (Winter, 2012) feed prices continue to hover around historic highs and although milk prices have risen they have not kept pace with the increases in feed costs. Feed costs are usually the largest single expense on a dairy farm and with well-above average feed costs, the feeding management and nutrition of the dairy herd must be scrutinized now more than ever. ...

Modern animal feeding includes prophylactic approaches for supporting intestinal homeostasis and immunity, in order to avoid dysbiosis, diseases, and need for antimicrobial medication. According to the principles of the One Health concept, the well-being of humans, animals and the environment are all connected, and at these times of a pandemic, avoiding the excess usage of antibiotics in animal farming is more important than ever. Pro-, pre- and synbiotics Prebiotics and...

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...

Feed flavours are additives that are being increasingly used in animal nutrition as a tool to enhance both the smell and taste of feed, in order to improve feed intake. It is generally observed that a higher feed intake in animals leads to improved performance and consequently a higher return on investment. ...

Introduction Complementary grazing systems (CGS) involve the rotation of animals between forage resources of species with different patterns of seasonal growth and development (Gillen et al., 1999; Moore et al., 2004). The aim of the CGS is to overcome the seasonal deficiencies in the production of dry matter and nutrients content that are inherent to the use of a single resource. The advantages of CGS include more efficient use of each forage resource and the subsequent...

Imminent VFD regulations are anticipated to create challenging conditions for dairy producers. Yeast products are one of the many options that are being explored to overcome these challenges. There is a wide range of yeasts and yeast-derived products available but with varying efficacy. Refined Functional Carbohydrates (RFC™) derived from yeast act through a number of mechanisms to alleviate production stressors leading to improved profitability. Some of these benefits include ability...

Silvopastoral systems One of the limitations for the efficient production of meat and milk in livestock systems of Venezuela is the scarcity of high-protein forage from plants adapted to the acid soils and prolonged droughts of the Llanos (savannas). The Llanos cover an estimated area of 15-20 M ha predominantly in the southeast and southwest of the country. They are mainly covered with native grasses (Trachypogon spp.), which have low carrying capacity (0.10-0.25 AU/ha; 1 AU =...

Introduction Feeding high-producing cows continues to challenge dairy farmers and nutritionists. Also, dairy profit margins vary as milk prices and feed costs shift yearly. Feed costs represent the largest input cost to produce milk (estimated to be 35 to 50 percent). Feed additives are a group of feed ingredients that can cause a desired animal response in a non-nutrient role, such as pH shift, growth,...
