Storing feed for livestock is essential in climates like Manitoba where a winter environment may make up half the year. Putting feed up and keeping it in good condition can be difficult, especially in wet summers. Feed spoilage is caused by the growth of undesirable molds and bacteria. Their rapid growth can cause heating of feed, which reduces the energy as well as the vitamins A, D3, E, K and thiamine available to the animal. In addition, moldy feeds tend to be dusty, which reduces their palatability.
It also slows the movement of material through the digestive system keeping the horse full and satisfied. Moisture is likely the hsated one limiting factor of storage life for roughages. Agri-News This Week. Fungi such as Aspergillus ochraceus and Penicillium viridicatum can produce ochratoxins in stored feed.

Barley is an annual cereal grain used for livestock feed and forage, as well as for malting. Barley cultivars are available for fall or spring planting.
Spring-seeded barleys are commonly planted in Midwest areas where well-drained, fertile soils provide optimum production. Barley grain can be arranged in two-rows or six-rows and hulled or hull-less. These different barley varieties result in various growth rates, feed intake and feed efficiency for pigs. Two-rowed barley produces fewer, but larger kernels per plant than six-rowed barley, so it generally has better feed efficiency, but lower grain yields per acre.
Hulless barley has higher crude protein and lower crude fiber than hulled barley, as the hull contains a large portion of the fiber. Barley has a similar nutrient profile to corn making it a versatile feed grain. Compared to other small grains, barley has a lower metabolizable energy ME value than rye and corn.
Like oats, barley has higher fiber content than other small grains because the kernels are encased in a hull. Barley also has a high heat increment content, which increases heat produced from feed digestion. High heat increments of a feed grain help to keep an animal warm in cold environments.
Keep in mind — during warm conditions, more barley will need to be fed due to lower feed intake caused by additional generated heat Iowa State Extension, Barley is well suited for grow-finish rations since feed intake is not a limiting factor and pigs can perform as well as they do on corn-based diets. Feeding Small Grains to Swine reports the high fiber content of barley does not negatively affect gains in growing-finishing pigs, and found pigs fed barley-based diets tended to have a higher quality fat than those fed corn-based diets.
Even though barley-based diets are lower in energy than corn-based diets, pigs can meet their energy requirements by eating more. Farmers like Ron Rosmann of Harlan, use barley in combination with other small grains like oats, wheat, triticale, and field peas to feed succotash. In the video below, Ron, Dan and Torray Wilson of Paullina talk about growing succotash for livestock.
Barley can also be used as the sole cereal grain in sow diets during gestation. The fiber in barley has a prebiotic effect reducing diarrhea incidences for starter pigs. Grow-Finish below lbs.
Grow-Finish above lbs. The value of small grains should be based on their nutrient contribution to the ration regarding digestibility and costs. However, when planted in rotation with corn and soybeans, winter barley keeps a living cover in the field to help protect soil health and water quality. Feeding barley in a mix like succotash can also lower feed costs. The relative cost of the two high and low rations, based on current market prices, is shown in the table below.
The table above highlights gestating sow rations with and without the inclusion of barley. From the two rations compared, the relative cost of corn and barley based on current market prices is shown in the table below. What is the cost of purchasing barley?

Part II. Several studies comparing two- and six-row barley varieties have not provided any clear-cut advantage for feeding. Barley quality parameters for North Dakota production are provided in Table 3.
Varieties designated as malting types often are used as feed and discounted in price when the grain lot does not meet the criteria for malting grade low protein, high test weight, high percent plump, low percent thin kernels and low deoxynivalenol [DON] level. High protein content is desirable in feed varieties. Hull-less barley has lower fiber and higher protein and energy levels than covered barley. Growing conditions and cultural practices may have a much larger effect on nutrient content and animal performance than varietal differences.
Variation in weather in barley-growing regions, year effect, soil fertility, pest management and harvest proficiency can affect barley grain quality significantly.
Bushel weight or other quality characteristics may be more useful in assessing feeding value than relying on variety alone. While opportunities exist for increasing the feeding value of barley through varietal selection, differences in feed value due to agronomic choices and growing conditions also pertain. No strong, consistent relationship exists between barley test weight and feedlot performance of beef cattle until test weights decrease significantly.
About 44 to 45 pounds per bushel test weight appears to be a threshold where gains are similar to heavier barley, but efficiency tends to decrease with decreasing test weight.
At less than 43 pounds per bushel weight, gains and efficiency are severely affected. Light test weight barley may be a mixture of shrunken and normal sized kernels, which in some cases were screened during seed cleaning or in preparation for malting barley purposes.
A number of studies have investigated whole barley vs. In general, animal performance with processed barley was greater than when whole barley was fed. Whole barley fed to beef steers averaged In this study, Barley has a fibrous hull, necessitating some form of processing for optimum utilization. Whole barley kernels are relatively undamaged during mastication, compared with corn Beauchemin et al.
This emphasizes the need for mechanical processing if beef cattle are to use barley effectively. Dry-rolling is the most common and least expensive processing method. Barley should be crushed or cracked so each kernel is broken into two or three pieces. A single-stage roller mill with 10 to 12 grooves per inch works better than a roller with six to eight grooves commonly used for processing corn or peas. Hammer milling barley is not recommended for feedlot cattle, but if it is the only processing method available, a large screen and slow rotor speed will reduce the amount of fines.
The grain should not be finely ground but rolled coarsely, with a particle size not less than about 3, microns. Barley ferments rapidly in the rumen Figure 1 , compared with some other grains, and fine grinding accelerates this process. Small particle size increases the surface area exposed and rate of fermentation, increasing the potential for subacute acidosis, founder and poor feed conversions. Feed additives such as ionophores and some yeast products help maintain a stable rumen environment, but proper grain processing, mixing of the ration and inclusion of some other fiber in the rations are critical for stable intake and digestion.
Variation in kernel size makes precise processing more difficult. In some cases, light and heavy barley may be blended to make a certain bushel weight grade prior to sale. Processing separate lots prior to mixing and feeding will improve the consistency of the feed.
Tempering involves adding water to barley and allowing it to soak for 12 to 24 hours to increase the moisture level prior to rolling. The target moisture content is 18 to 20 percent. Higher-moisture barley rolls more easily, resulting in more of a flaked product than dry, hard pieces of barley kernels.
The advantages of tempering include fewer fines produced during the rolling process and improved ration acceptability. Rolling tempered barley required Tempering and rolling barley increased intake and gain vs. Decreasing the flake thickness of tempered rolled barley increased the digestibility of starch Beauchemin et al. High-moisture barley grain can be harvested up to 12 days sooner than dry barley with up to Moisture at harvest should be 25 to 30 percent, with higher moisture levels possible, but kernel fill may not be complete.
High-moisture grain must be processed immediately and stored as one would silage. Appropriate preparations for high-volume processing and storage are needed to facilitate rolling or grinding and storage of grain being harvested. Bunker or upright silos or large plastic bags are useful for this purpose. Properly processed and stored high-moisture barley will ensile and become brownish yellow, giving off a distinctive fermented malt-alcohol odor.
High-moisture barley feeds as well as dry barley, with the advantages of extra yield and the grain is already processed for feeding. Barley starch may act as a binder in manufactured pellets but the optimum level of inclusion has not been determined. Pelleting barley in combination with other ingredients may work in modest-energy growing diets; however, dry-rolled barley supported improved performance better than pelleted barley in finishing trials Williams et al. No advantages in average daily gain, feed intake and feed efficiency were observed when steam-rolling or flaking was compared with dry rolling or temper rolling barley in feedlot diets.
While marbling scores increased for steers fed steam-rolled barley Hinman and Combs, , other trials have reported mixed results for carcass quality Grimson et al. Barley is an excellent feed grain in forage-based diets. Corn silage-based rations with dry-rolled barley, chopped hay, distillers grains and a commercial supplement have been used frequently for weaned steer calves at the Carrington Research Extension Center. Barley is included in the total mixed ration TMR at 6 or more pounds per head daily, depending on the gain goals for the cattle.
Dry-rolled barley added to grass silage-based diets increased weight gains and improved feed efficiencies for growing calves. Berthiaume et al. Ground barley processed to a smaller particle size than dry-rolled barley should be fed in forage-based diets in limited amounts because the smaller particle size can induce digestive problems. Ground barley fed at 1. Barley provided more rumen-degradable protein, which supports improved forage NDF digestion Brake et al.
Barley fed at less than 4 pounds per head per day in a forage- or silage-based diet for wintering or growing cattle or for beef cows can be processed to a smaller particle size because the increased fermentation rate is offset by the high proportion of forage in the diet.
High-forage diets increase the passage rate in the gastrointestinal tract, allowing less time for digestion of larger particles of grain. In addition, the dusty nature of finely ground barley is mitigated by moist silage, molasses, fat, liquid supplements or other ingredients. Bengochea et al. Barley processed to a smaller particle size improved starch digestion and feed efficiency in cattle fed medium-concentrate growing diets. Barley can be added during the ensiling of grass or corn silage to increase energy and protein, but it should be rolled for optimum animal performance Jacobs et al.
Adding barley to moist forages at ensiling increases dry-matter percent and reduces effluent losses, but less precision results in the ration when feed ingredients are mixed at the silage pile. Barley can be used as the only grain in finishing rations. Best results are obtained when the TMR includes a modest amount of forage and an ionophore at the recommended rate. Exceptional bunk management is required to keep cattle on feed when forage levels are minimized below 12 to 15 percent.
Forage quality may affect gains and feed efficiency, but alfalfa should not be fed in rations with a high percentage of barley due to the potential for bloat. Feeding more than one grain may have some advantages due to the palatability of multiple feed grains in a ration and the complementary rates of ruminal starch digestion. Blending grains can help stabilize rumen function, resulting in more consistent intake. Corn and barley fed at reciprocal inclusion levels of 0, 33, 67 and percent grain in finishing diets supported equal gains and feed efficiency when distillers grains were included in all the rations at 23 percent of the diet Anderson and Ilse, unpublished data.
Barley and corn combinations performed similarly in other trials Duncan et al. Field peas grown in the same eco-regions as barley make an excellent complementary protein source in barley-based rations Ilse and Anderson, Distillers grain is especially important in barley-based diets because bypass protein from the ethanol coproduct balances the rumen-degradable protein of barley.
In addition, distillers grain provides energy from fat corn oil and additional fiber from corn bran that may mediate the fermentation rate of barley starch. Any level of distillers grain 12, 24 or 36 percent of dry matter added to barley-based growing diets improved feed intake and gain. In a companion finishing study with the same levels of distillers grain tested, 24 percent distillers grain supported the fastest gains, and all carcass traits except rib-eye area improved linearly with increasing distillers grain levels Anderson et al.
Cattle fed barley will benefit from including an ionophore in the ration to stabilize rumen function and maximize feed efficiency and gain. Ionophores improve gains in high-forage diets without affecting intake, while in finishing rations, gain is not affected, but feed intake generally is reduced, resulting in greater feed efficiency. Some commercial products such as yeasts and enzymes may be effective in barley-based diets.
Consider unbiased research when selecting feed additives. Barley is higher in fiber than other cereal grains National Academy of Sciences, Engineering, and Medicine, and the fibrous hull is relatively low in digestibility. Rolled barley treated with an enzyme mixture of cellulase and xylanase enzymes increased ADF digestion by 28 percent Krause et al. Fibrolytic enzymes xylanase used in barley rations resulted in improved feed efficiency with no differences in average daily gain or feed intake Beauchemin et al.
More research in this area is warranted as new products are developed. Increasing the level of supplemental barley grain 10, 30 or 50 percent of the diet dry matter for grazing cattle consuming brome grass resulted in increased average daily gains and improved feed efficiencies Leventini, ; however, digestion of NDF decreased as barley supplementation increased.
Soybean meal 1. Forage intake decreased with each of the supplements, compared with nonsupplemented cattle, but total intake did not differ among treatments.
Barley supplementation resulted in lower NDF digestibility, compared with other treatments. Forage intake decreased when barley was fed at 5. Forage intake was reduced when 4 or 6 pounds of barley was fed but was not affected when 2 pounds of barley was used as a supplement.
Digestible organic-matter intake was higher in diets that contained supplemental barley, however. Lardy et al. Barley is a very useful supplement for gestating beef cows fed low-quality forage. The level of barley fed will affect forage digestion Boyles et al. Barley provides energy from starch and rumen-degradable protein nitrogen necessary for healthy populations of forage-digesting bacteria in the rumen.
Too much barley starch will affect the population of fiber-digesting microbes negatively and reduce forage digestibility. If higher levels of supplemental energy are required, feeds with more digestible fiber such as barley malt sprouts, wheat midds, soy hulls, corn gluten feed, beet pulp, oilseed meals and distillers grains may be more useful. The negative effect of excessive starch in a high-forage diet is not considered in ration-balancing software.
Momont et al. Both were equally effective as supplemental feeds. Cows fed the barley supplement consumed more ammoniated straw than cows fed the beet pulp supplement, and no adverse effects of barley on forage digestibility were noted. Cows fed a barley-cottonseed meal cake gained 31 pounds during the trial. Cows fed 2. Unsupplemented cows lost 24 pounds during the study. Vomitoxin, also known as deoxynivalenol DON , is a trichothecene mycotoxin produced by Fusarium fungi in scab-infected grain.
DON-infected barley is rejected for malting at relatively low levels 0. While DON can cause problems for swine reduced feed intake, vomiting , no evidence exists that beef cattle are affected adversely, based on multiple research trials with cows and feedlot cattle. First-calf heifers were fed dry-rolled barley with Finishing cattle were fed barley infected with up to Barley infected with DON up to 21 ppm was fed to growing and finishing cattle without adversely affecting feedlot performance or carcass characteristics DiConstanzo et al.
However, grains contaminated with DON often are contaminated with other mycotoxins encompassing a wide range of compounds.
Current Food and Drug Administration guidance www. Barley is a cool-season crop that can be planted early into cool soils. Barley is a very competitive plant that matures quickly and can be harvested for forage in approximately 58 to 65 days.
Given the short growing season, barley could be planted in some environments for double cropping. The seed cost for barley is low, and seed can be saved from most varieties for reseeding. Some specific barley varieties have been developed for annual forage, and seed often is available commercially.
Barley varieties developed for forage are generally awnless and can be harvested at a later stage of maturity milk-soft dough stage , compared with grain varieties. Forage barley varieties can be two-row or six-row types. Rosser et al. Awned varieties developed for grain production can be used for forage, although they need to be harvested shortly after heading to avoid mature awns, which can be irritating to the mouth of cattle. Barley can be grown as a monoculture or planted with peas to produce forage with increased protein and greater yield.
Trials at various university and seed company plot sites around the region provide localized forage yields and quality information. Forage barley or barley-pea mixtures can be harvested and stored as haylage if the crop is wilted to 40 to 60 percent moisture. Forage barley or mixed barley-pea stands can be harvested as dry hay as well. The stage of maturity at harvest will make a significant difference on the quality of the forage. Harvesting at heading to milk stage is recommended for optimum quality, although the soft dough stage may yield slightly more forage and still provide reasonably good quality.
The addition of peas allows the forage mix to be harvested at a later stage to increase yield while still maintaining high-quality forage. Barley or barley pea mixtures harvested as hay or silage can be used as forage in feedlot rations as well as in beef cow diets. Barley straw may be used as forage when properly supplemented, but awns are a concern.
Barley grain is a useful feedstuff for several different classes of beef cattle. When properly processed, mixed and fed, barley is an excellent feed grain. It can be used in growing and finishing diets for feedlot cattle, as supplement in forage rations for replacement heifers, and as an energy and protein source for gestating and lactating beef cows.
Research indicates beef cattle are less affected by DON than monogastric animals. Barley processing requires careful attention to maximize digestion efficiency and maintain stable rumen function. Thorough mixing of rations and good bunk management are essential with barley rations, as with other grains.

Storage Life of Livestock Feeds - Frequently Asked Questions
Does feeding management or individual feed ingredients really influence the behaviour of horses? Scientific research on the effects of feed or feeding management on horse behaviour is scarce. Given this opportunity, the horse will graze for approximately 16 — 18 hours per day, assisting a slow, continuous intake of fibrous feed into the digestive system. These horses often finish their meals — that often consist of high-energy grain and limited amounts of hay or chaff — quickly and then stand for long periods of time waiting for the next meal, with little to no natural exercise.
The combined result is an increase in stereotypic behaviours such as cribbing, wood chewing, weaving and stable walking. Possible explanations include frustration due to confinement, lack of socialisation with other horses, acid accumulation in the digestive system as a result of a low fibre, high grain intake leading to pain, or simply a lack of exercise leading to pent up energy. First, horses need to be provided with an adequate amount of forage.
Horses require a minimum of 1. Another management tool is to feed smaller meals on a more frequent basis, for example feeding three or even four times per day keeps horses occupied, alleviating boredom and frustration.
It also slows the movement of material through the digestive system keeping the horse full and satisfied. Finally, giving horses an opportunity for turnout in a paddock or an arena will provide exercise and allow horses to expend pent up energy. Turnout for as little as 30 minutes twice a day will help keep horses mentally healthy and avoid negative stereotypic behaviour.
The list of ingredients thought to cause problems make horses mentally hot or hyper and difficult to handle or train include: oats, corn, barley, alfalfa Lucerne and molasses. Several possible explanations exist for why these ingredients may alter behaviour in horses. First, each of these ingredients contains a significant amount of calories and the negative behaviour may simply be a result of overfeeding calories to horses that are not adequately exercised. Since an overfed horse would have plenty of energy and they are not getting adequate turnout or forced exercise, they may channel the energy into negative behaviour.
Starch and Sugar: A more scientific explanation for the change in behaviour may have to do with the sugar and starch content of the diet. Sugar and starch are found in large quantities in cereal grain and when it is digested in the small intestine of the horse the end product is glucose, which is absorbed into the blood.
Fluctuations in blood sugar may be the cause of behaviour changes. Research has demonstrated that horses fed the exact same number of calories as either starch or fat had more spontaneous activity and reactivity to stimuli when fed a starch-rich diet compared to a fat supplemented diet. Simply stated, more research is needed to answer this question, which brings up another interesting question.
If changes in blood sugar cause behaviour changes then why do not all horses have behaviour changes when fed grain? The answer may lie in the fact that horses have large differences in their ability to digest starch and thus alter blood sugar. Serotonin: Another interesting theory for the reason certain feeds may cause behaviour changes revolves around the brain neurotransmitter — serotonin.
It is important to understand that this theory has not been tested or studied in detail in horses, however for humans, serotonin functions to regulate mood — low levels of serotonin are often associated with depression. Thus, many human depression medications function to increase the level of serotonin in an effort to improve mood. In the human body, high levels of glucose from the digestion of starch increase serotonin levels. This improves mood, making humans more alert and active.
So if attempting to apply this theory to horses, realizing this has not been thoroughly studied in horses, a picture may be painted that high starch grain diets result in high levels of serotonin and the horse feels good and becomes more active ie. Excess protein fed to horses can be metabolised and utilised for energy, however, protein itself does not seem to influence behaviour. The individual effects of amino acids, the building blocks of protein, have not been studied to determine their effect on mood or behaviour.
To change or modify this behaviour the horse simply needs to be trained so the energy is channelled into positive work rather than poor behaviour. Molasses in feed can be partially replaced with rice bran oil, an ingredient that does not contain any sugar. Feeding the grain concentrate portion of the diet in three meals per day instead of two meals per day may also help minimise large fluctuations in blood sugar.
Finally, feeding a larger volume of good quality hay or pasture provides additional calories and helps minimise the amount of grain that must be fed to maintain body weight. Overall, these feeds generally contain lower sugar content, thus potentially resulting in less negative behaviour if fed correctly. Supplements that claim to calm horses typically have several common ingredients including thiamine and magnesium, as a deficiency of either the B-vitamin thiamine or the mineral magnesium results in nervousness, anxiety and even convulsions.
Typical diets fed to horses are rarely deficient in either thiamine or magnesium. Adequate research has not been conducted to validate the effectiveness of these supplements, although over-supplementation of the diet with these two ingredients does not result in toxicity issues. There are several herbal ingredients that may be used to calm horses; unfortunately, many of these are banned substances that cannot be utilised in the diets of competition horses.
Care must be used in administering any of these products to horses. Thanks for this info, it was very informative… I will be trying to et my local outlet to get these 2 products in if I can..
