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...

Enzymes have been used extensively in the diets of poultry and pigs, and as silage additives, but, until recently, not much in the diets of ruminants (Beauchemin et al., 1995; Beauchemin et al., 1999a; Yang et al., 1999), due to the view that feed enzymes would be rapidly degraded in the rumen before they could have any effect (Beauchemin et al., 1995; Beauchemin et al., 1999a; Kung et al., 2000; Bowman et al., 2002a) and due to the high cost of enzymes and inconsistency of responses (Yang et...

Introduction The concept of strategic supplementation is the art and science of putting the appropriate supplemental feed in front of the cow at the right time. To understand the idea of strategic supplementation the word "strategic" needs to be defined. The online dictionary defines "strategic" as 1) "pertaining to, characterized by, or of the nature of strategy; 2) important in or essential to strategy; 3) forming an integral part...

Magnesium oxide is the most common form of supplemental magnesium used to prevent grass tetany. So if your cattle graze pastures where they have experienced grass tetany, magnesium oxide supplementation is necessary. Magnesium oxide is not very palatable and has been characterized as having a bitter taste. Livestock are often unwilling to consume it at recommended levels, making free-choice supplementation of magnesium oxide to grazing cattle sometimes a challenge. Feed companies have...

An in situ trial was conducted to evaluate effects of corn moisture and length of ensiling on dry matter digestibility (ISDMD) and degradable intake protein (DIP). Corn treatments consisted of dry-rolled, high-moisture, and reconstituted dry corn. Corn samples were incubated in situ for 22 hours and ISDMD (%) and DIP (% of CP) values were calculated. Both highmoisture and reconstituted corn had higher ISDMD and DIP values than dry-rolled corn. Dry matter digestibility and degradable...

This factsheet can both guide producers through a feed test and help them understand the results. With a feed test in front of you, look at the following rules and compare them to the feed test. Remember, these are rules of thumb, which means they hold true most of the time, but variations in management and cow type will affect the end result. These rules of thumb should not be considered a replacement for balancing rations with proven software, but rather an aid to...

Cows calving during January through March are right now experiencing their highest nutrient demand for the year. This comes at a time when the quality of feed they are offered is often less than the best. This mismatch between feed quality and cow nutrient requirements can have serious implications later.
The economic situation has put cow-calf producers in a cost-price squeeze. Costs of a lot of inputs are higher than they have been historically (except for the ridiculous levels...

If more time was spent discussing the nutrient requirements of beef instead of the merits of different management systems, all the cows would be better off.
Winter continues to pummel us with extreme cold, wind and snow. A normal winter, if there is such a thing, occasionally gives us a breather, but not this year.
Winters like this year create discussion about what type of cattle operation is best. Despite the discussion, the fact remains that the...

Bahiagrass is the most predominant forage for grazing cattle in Florida. It is resistant to overgrazing and most pasture pests. Also, bahiagrass is adapted to grow in multiple Florida soil environments. In recent years, concerns have arisen about sulfur deficiency in Florida bahiagrass. In the past, fertilizer impurities provided pasture forages with supplemental sulfur, but the refinement of modern fertilizer manufacturing processes has made sulfur contamination uncommon. Therefore, the...

A study that involved a comparison of four types of round bale hay select feeders was conducted by Michigan State Univ. researchers. The types of feeders were cone, ring, trailer, and cradle. A total of 160 non-lactating pregnant beef cows were assigned to the four feeder types. Each of the four types provided approximately 17 inches of linear feeder space per cow. During the study, the hay that fell onto a concrete surface surrounding the feeder was considered waste, and was collected and...

A mineral supplementation program should simple, economical, and meet the needs of the cow herd as they change from one phase of production to another, and as they change diets (grazed pastures to harvested forages). These kinds of strategies have a good chance of being implemented. Calcium and P are probably the two minerals that most cow/calf producers should focus on especially when feeding harvested forages and before and during the breeding season. Phosphorus is...
