(sī`lĭj) or


(ĕn`səlĭj), succulent, moist feed made by storing a green crop in a silosilo,
watertight and airtight structure for making and storing silage. Silos vary in form from a covered pit, such as was used by the early Romans, to the modern storage tower, dating from the 19th cent.

. The crop most used for silage is corn; others are sorghum, sunflowers, legumes, and grass. In a sealed silo, typically in the past a tall cylindrical structure but often today in a surface pile covered tightly with heavy-gauge plastic, the crop ferments for about one month. This fermentation process, called ensiling, produces acids and consumes the oxygen in the silo, preserving the plant material. In pit ensiling, compacted silage ferments in an unsealed underground enclosure. Silage replaces or supplements hay for cattle, horses, and sheep. It is rich in carotene, an important source of vitamin A. A machine called an ensilage harvester cuts and chops the crop in one operation, preparing it for storage in the silo.

a succulent feed preserved in an airtight container. Corn, potato, sunflower, vetch-and-oat, and other silages are distinguished. Silage is close in nutritive value to the green material that is ensiled. Carotene and vitamin C are preserved in silage, as are smaller quantities of water-soluble sugars. Organic acids are also present: lactic acid (up to 2 percent), acetic acid (up to 0.6 percent), and, in certain types of silage, propionic and valeric acids. When improper ensiling and storage procedures are employed, butyric acid may be present.

The feed value of silage depends on the ensiling method, on storage conditions, and on the type of plants used and their stage of development at harvesting. One hundred kg of sunflower silage contain approximately 16 feed units, 1.4 kg of digestible protein, 350 g of calcium, 160 g of phosphorus, and 1,500 mg of carotene. An equal amount of corn silage has approximately 20 feed units, 1.4 kg of digestible protein, 150 g of calcium, 50 g of phosphorus, and 1,500 mg of carotene. In 100 kg of alfalfa silage there are 18 feed units, 2.9 kg of digestible protein, 600 g of calcium, 60 g of phosphorus, and 2,500 mg of carotene.

Good silage is pale olive or yellowish in color; silage that has been exposed to a great deal of heat is dark brown. The odor of silage is reminiscent of sauerkraut or of soaked apples; it is sometimes fruity. When a great deal of warming has taken place, the odor resembles that of freshly baked bread or of honey. Spoiled silage smells like spoiled herring or manure. Silage must be crumbly in texture; an oily consistency indicates spoilage. With a moisture content of approximately 70 percent, the pH of good silage is 4.2. When the moisture content is 65 percent, the pH is somewhat higher.

The consumption of silage improves digestion and facilitates better utilization of other feeds, especially roughage. All farm animals are fed silage. Silage may constitute as much as 50 percent of the nutritive value in rations for dairy and beef cattle and as much as 20 percent in rations for swine. Special silage is prepared for calves, swine, and poultry. Silage for calves is prepared from legumes, soft cereals, and mixtures of legumes and cereals harvested during the early stages of development. For swine, combinations are used, consisting chiefly of sugar beets, carrots, potatoes, melons, and corn cobs. Silage for poultry consists of legumes, vitamin-rich gourds, carrots, beet tops, and sugar-beet roots. Silage is fed in the winter and, in arid regions, in the summer as well. In the USSR the total consumption of silage by cattle and poultry was 166.7 million tons in 1965 and 185.3 million tons in 1974.



Green or mature fodder that is fermented to retard spoilage and produce a succulent winter feed for livestock.

Being airtight and subject to direct sunlight, there is a large amount of gas and silage liquor produced in the ag-bags which needs maintenance by the owner, typically by releasing the gas to avoid the bags bursting and removing of the liquor to stop the polluting liquid escaping and getting into the environment.
The previous studies reported that application of hybrid had effect on fermentation quality and aerobic stability of corn silage [11-13].
However, DMP also has a high content of total phenolics which have the capacity to inhibit the growth of various bacteria including gram positive bacteria (Butkhup and Samappito, 2011), thereby, potentially hindering the establishment of a stable silage. In addition to the WSC content, the number of epiphytic LAB on forages also are important to ensure the rapid establishment of a stable silage.
"The financial implications of getting it wrong are high, with losses typically adding over 25% to the cost of silage production," said Dr Davies.
speciosa) (ICBP) combined with ingredients based on natural matter (NM), in the following proportions: BM = ICBP+ 25% broken maize; BR = ICBP+ 25% broken rice; CS = ICBP+ 25% cassava scrapings; CC = ICBP + 10% coffee husk + 15% broken maize; and SC = sugarcane silage. In addition, the silage was inoculated with Lactobacillus plantarum (Silobac[R] 5), with a minimum guarantee of 1 x [10.sup.-11]CFU.[g.sup.-1], following the manufacturer's recommendations: 1g of inoculant for 1 t of silage, at a concentration of 2 L of solution.
Preserved form of fodder which is known as silage made from different cereal crops especially of corn is getting more prevalent as main dairy animals feeding requirement (Kljak et al., 2017).
Their attention to detail on their dairy farm was very impressive and their rations were well formulated to make full use of their excellent silage and the way that father and son worked together impressed me.
The analysis shows the intake potential, the value of the feed to the animals, it identifies possible problems or health impacts on the cow and allows the farmer to reflect on possible causes of unsatisfactory quality.Put it in another way, the results offer the farmer a chance to learn from mistakes and make informed decisions when making subsequent silage for better quality.
The addition of leucaena (Leucaena leucocephala) may be a good option for ensiling with sorghum due to its nutritional qualities, tolerance to water stress and its high productivity (Silva et al., 2015), and there is little known about this type of silage. In this sense, the goal of this study was to evaluate the effects of leucaena addition on sorghum silage at the time of ensiling.
Big Bale silage AN 850-acre farm with a five-cut grass system, producing more than 3,000 bales of silage, was the winner of the all-Wales title.
Right Agri's Eugene Gabriel says the variety is mainly intended for silage making but it can also be planted for grain production.
