Summer-annual grasses provide excellent forage during the summer. Small grains can be mechanically harvested as silage or hay and can ease fall or spring. pastures during drought can further weaken plants. Grazing during times of low moisture, the effects of drought will Lack of adequate forage during drought. Semi-dormant alfalfa varieties have been heavily promoted and widely adopted, as part of an effort to maximize forage production during the upper Midwest’s.

Tall Fescue, Orchardgrass and Timothy The majority of pastures and hayfields in Tennessee contain either tall fescue, orchardgrass durig timothy.
They can be valuable in the development of a year-round forage system. These forages have the potential to provide hay and grazing during the summer, when cool-season grasses are less productive due to drought and heat. Increase N, P 2 O 5K 2 O fertilization by a third if the crop will be harvested as both pasture and grain.
They will make high-quality feed if the plants are cut when the seed pods are still green. Soft Red Winter Wheat is an excellent fall and spring pasture which is didig in digestibility. As drought sets in, the herdsman can temporarily lower stocking densities fewer grazing animals per acrestretch available forage with hay or supplemental feedstuffs, or even lower the nutritional needs of animals.
Issued in furtherance of the acts of May 8 and June 30, The most common usage is for late-summer or fall grazing.
As these plants mature, they will be higher in fiber which reduces the feeding value. Dry females have their lowest nutritional needs in early to mid pregnancy.
Forage Species|UT Beef and Forage Center
If grazing begins before a sufficient re-growth has occurred, this additional stress will prevent the plant from accumulating reserves for future regrowth and will cause further thinning of stands. They are more likely to contain toxic levels of prussic acid than are other summer-annual grasses.
Although these species are termed forzge, many continue to be productive throughout the summer. A stalk chopper and hay rake should be used before baling. Soil tests should be taken and fertilizer applied according to the soil-analysis results. Summer Annual Grasses Livestock production in Tennessee is based on cool-season perennial forages such as tall fescue and orchardgrass.
Early weaning and pasture supplementation strategies for beef cattle are presented in Drought Management Strategies for Beef CattleUniversity of Georgia Extension Bulletin Soybeans can be used for hay or silage, should the need arise. These tactics, categorized in order of early, advanced, and severe drought stages, are based on specific characteristics including water loss, forage growth, and rainfall.
Using Sweet Bran instead of forage during grain adaptation in finishing feedlot cattle.
Forage and Field Crop Seeding Guide for Tennessee This guide includes recommended species, seeding rates, planting dates, planting methods, and other important facts on the forage. Associated with the increased yield was reduced forage quality. Since the need for extra forage usually becomes obvious after row crops have been planted in the early spring, summer-annual grasses are a good double-crop option when planted after a small grain has been removed as forage late May-early June or grain late June-early July.
Mid-season, tall-growing varieties will provide the highest yields. During this period, cool-season grasses produce very little growth and shortages can quickly occur if moisture is inadequate. Split nitrogen applications will help reduce these problems.
Forage Use and Grazing Herd Management during a Drought | UGA Cooperative Extension
In general, ruminants are more susceptible to prussic-acid poisoning than swine or horses. Table 3 of this publication gives establishment information. Alfalfa High-quality Forage Production Alfalfa scientific name Medicago sativa is one of the most well-known and widely used forage crops in the world.
Cool-Season Perennial Grasses Grasses in this category tend to predominate forage programs in Tennessee. It usually contains lower levels of prussic acid than sorghum-sudangrass hybrids, but is also lower yielding. Using an up-to-date forage and feedstock inventory, calculate exactly how many animals if any that the operation can feasibly carry through the drought.
As a result, plant growth slows. Crop residues are a very economical source of feed to supplement pastures. Seventy-five pounds of N per acre is recommended. Having both makes legumes a component of the pasture that we should focus on constantly. These Legumes make most of their growth in the winter and spring. Small Grains Annual Ryegrass.
Summer-annual grasses respond best to rotational-grazing systems. Spring oats may be sown in August for fall pasture, but it will be killed by frost and will not produce spring growth. Pay close attention to the long-range weather forecasts and the current market.
Furthermore, toxic compounds like nitrates or prussic acid may be present in high concentrations following a drought.
Make proactive management decisions in order to minimize damage from sustained drought stress. With proper management, salt, mineral, and vitamin A are the only supplemental feed required for mature beef-cows grazing corn residue during the first third of gestation.
By paying attention to the “percent-purity” figure on the seed tag and purchasing quality seed from a reputable dealer, many of these problems can be eliminated. Triticale, a nontraditional small grain, can also be used for these purposes. Silage should be made when the “black layer” forms.
Corn silage, crop residues, and soybeans can also be utilized by the livestock producer to help meet forage needs. Just as with warm-season annual grasses, these grasses tend to be expensive, so their use should be limited.
Extension Changes Georgia University of Georgia Cooperative Extension programming improves people’s lives and gets results. When summer-annual grasses are harvested at the proper growth stage, digestibility will be moderate to high and animal performance will be good. Some of the more traditional crops that can be used for emergency or supplemental forage include small grains such as wheat, rye, barley, and spring oats.
The result of this cross will be a plant that may or may not have rhizomes. These factors indicate that as far as animal feeding is concerned, small-grain forage can be substituted for orchardgrass or low-endophyte tall fescue on a one to one basis.
Brassica Crops turnips, kale, and rape can be described as high-yielding, high-quality, and fast-growing biennial crops.
