Introduction Sugar is a concentrated energy food. However, it is not documented as a vital nutrient for humans. If we never had another teaspoon of dietary sugar in our life, our nutritional health would not be affected in the slightest. So from a health view point sugar is valueless. Sugar is traditionally seen as a danger to blood-glucose levels. The US Dept of Agriculture recommends that sugar makes up no more than about 8...

Lipids are metabolic regulators of reproduction in dairy cattle. As pregnancy losses are substantial in dairy cattle, it is necessary to implement strategies to counter this issue. Among them, nutritiona ones, and particularly fatty acids, are day by day proven to be more effective. Early stages of conceptus development constitutes a window of action, as this period requires substantial coordination of lipid metabolism by conceptus cells (changes in concentration or composition of fatty...

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...

Relative feed value has been used for a number of years to indicate the overall feed value of forage. In recent years, there have been some changes considered to make this assessment more accurate in regards to predicting the feed value of forage. It is well accepted that there is a correlation between the acid detergent fiber (ADF) portion of forage and the energy value of the forage. One of the problems has been that different labs will use different methods of calculating the energy...

Introduction With the increased cost of grain and forages in the USA, dairy producers have turned their attention to the feed efficiency of milk production. Low on-farm starch digestibility contributes to reduced feed efficiency. Several researchers have demonstrated that measuring fecal starch (FS) is highly correlated to total tract starch digestibility in dairy cows. One factor affecting the digestibility of starch in...

Introduction Grouping cows is a common practice farmers use to manage their herd more efficiently. Farmers use this strategy to separate far-off, close-up, sick, fresh, and pregnant cows. Grouping addresses cows’ specific needs. However, grouping lactating cows for nutritional purposes and providing groups with more precise diets has not been adopted as widely as it could be, despite the fact that many studies...

Why use organic micro minerals? Use of organic micro minerals (Zn, Cu and Mn) has a positive effect on hoof health, udder health, reproduction and milk yield. How are inorganic micro minerals absorbed? Inorganic micro minerals have to be dissolved in the digestive fluid (is transformed into ionic form) and then bound to a suitable adjuvant...

A robust immune system is vital for dairy cows to live long, healthy, and productive lives. Multiple factors affect the immune system, and, arguably, good nutrition is one of the most significant keys to efficient immune function. Research shows a properly functioning immune system uses key diet components, including vitamins, minerals, energy, and antioxidants.
Vitamins Immune system function can be significantly impaired...

1. Introduction. The intensification of grazing dairy systems has led to an increase on the use of supplements and more recently on the use of total mixed rations (TMR) (Wales et al., 2013), particularly when imbalances between herbage production and herd requirements occur during the course of a year (Chilibroste et al., 2007; Wales et al., 2013). Increased levels of TMR...

Introduction Over millennia, grazing ruminants have, for the most part, evolved on the great grasslands of the world, ranging from the savanna and tropical grasslands of the equatorial regions to the temperate grasslands at slightly higher latitudes. Less extensive are the high-altitude alpine pasture and marginal tundra biomes, in which many unique distinctive breeds and species of livestock have evolved, which, although...
