Additives and feedstuffs in dairy cattle nutrition
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 United States dairy production has continued to grow despite competition for land and other agricultural resources from other agronomic and livestock/poultry alternatives. More efficient utilization of resources has now become a major objective of many dairies as they increase the size of their dairy herd despite a limited land base. In the Midwest and Northeast U.S. this growth has been driven by increases in use of corn silage, increased...

In ruminants concentrates, oils\fats inclusion is lower that in monogastrics' ones, where low durability and pasty textures can be found due to high inclusion of fats. In ruminants diets, where fats level of inclusion is lower, do you have any data\and or experience regarding the effect of calcium soaps of fatty acids (and\or hydrogenated fats) on pellet quality? ...

Over the past few years, the dairy industry has made it a priority to feed higher forage diets with a correct balance of amino acids and an accurate ratio of lysine to methionine. With this strategy, there also has been more attention on the amount of undegradeable protein (RUP) being fed.
“We are feeding more high forage diets than we ever had in the past,” said Gene Goenner, territory product representative for Alltech Wisconsin. “With this feeding...

Crude protein (CP) is a required nutrient for dairy cattle, typically ranging from 15 to 18% on a dry matter basis. Dietary CP is often the most expensive macronutrient, and there’s been considerable interest in reducing the inclusion rate of high protein ingredients to decrease costs. In addition, there’s greater focus on reducing the environmental impact of the dairy industry, with much of...

Introduction Modern day intensive production systems, especially with high producing dairy cows, involve the feeding of high levels of concentrates in order to supply sufficient nutrients to support a high level of milk production. Feeding these high levels of concentrate often leads to metabolic dysfunction and eventually rumen acidosis; especially under conditions of poor methods of feeding and/or composition of diets. Ruminal acidosis can be...

We conducted a study evaluating the growth performance and total tract nutrient digestion of heifers fed diets high in distillers dried grains with solubles (DDGS) with different forage particle size. Particle size is important for rumen fermentation and rumination. Large forage particles help stimulate rumination which aids in buffering with saliva. Buffering may be important when considering feeding DDGS because it is considered an acidic feedstuff with a pH...

Introduction The objective of this article is to briefly describe the most common ethanol coproducts, how they are produced, and typical nutrient compositions. Rapid growth of the ethanol industry in the United States over the last decade has generated large quantities of ethanol coproducts, which are now commonly available as feedstuffs for livestock. These coproducts are often added to livestock diets as a source...

Feeding has been evolved to be an important tool to in feeding to support animal production. When the production enhancement was considered a task in animal industry balanced animal rations were developed. The ration consists of forages, grain, protein meals and other concentrate feeds. The above ration may contain elements required and not required by the animal. It was arduous to separate the not required elements which may require sophasticated process...

Grain producers are often looking for ways to increase revenues from their land. In the Upper Plains it might not be economical, or even practical, to plant another grain crop during the growing year; however, it may be in the producer’s interest to consider a cover crop. Cover crops provide multiple benefits to the producer and the environment. The primary benefit is additional forage production from the growth of the cover crop which can be used by the...

Introduction Pakistan is comprised of large number of livestock population with a contribution of more than half 50 % value added share in the agricultural GDP. Livestock are the back bone of the socio-economic structure of the small land holders in the rural areas of the country (Raza and Rowlinson 2004; Raza et al., 2000 and Sultan et al., 2007, ). The land allocation for livestock production is continuously reducing...

- What kind of hay is suitable for haylage?
- Do we need to use inoculant for it?
- When is the adequate cutting time?
- What is the limit of use?
- What kind of equipments do we need?
- What is the adequate moisture to cut?

Feed prices for the last 5 years have been at historic highs. Coupled with periods of low milk prices, this has resulted in extremely tight (sometimes negative) margins for dairy producers. The ability of ruminants to convert lower digestibility feedstuffs (forages and other high fiberfeeds) into useable products has always been a positive attribute and one that has historically allowed the use of lower cost feedstuffs,...
