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...

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...
