Forage crops for hogs
… rape, rye and corn are the most important forages for hogs and should be contained in every rotation if possible. 2. That corn, shorts and tankage are the best concentrates both for the growing hog and for the breeding herd. 3. That growing hogs should receive a full concentrate ration of …

Grasshopper species complexes of forage crops in the piedmont region of Virginia
Field collections of grasshoppers (Orthoptera: Acrididae, Tetrigidae, and Tettigoniidae) from twenty hayfield and pasture sites in twelve counties in Virginia were made in 1979 and 1980. Fifteen Acrididae, two Tetrigidae, and six Tettigoniidae species were found among the 20,793 grasshoppers …

Stock wintering systems in Southland
… have occurred in Southland. The area of forage crops for wintering stock has greatly decreased with the development of low cost wintering systems. The change in emphasis from crop to grass wintering of livestock may have affected production per animal and per hectare. Several farming …

The effect of winter grazing and a nitrification inhibitor on nitrous oxide emissions and denitrification in a stony soil
Intensive grazing of forage crops by dairy cows is common practice during the winter months in the Canterbury region of New Zealand. Such intensive grazing on wet soil increases the risk of denitrification and the production of the powerful greenhouse gas, nitrous oxide (N₂O). However, at the …

Control of green June beetle larvae attacking pastures, and residues resulting from insecticidal treatments
… capable of almost completely destroying certain forage crops such as alfalfa and clover, not by direct feeding, but from the results of their search for food. The adult, although not of prime economic importance in this region, does cause considerable economic losses. It feeds on fruits from a …

Some Life History and Ecological Activites of the Richardson Ground Squirrel In South Dakota
… natural predators. With the advent of cultivated crops, the range herbivores found a new and tasty source of food. Among these primary consumers which took advantage of man’s interference with the natural prairie was the Richardson ground squirrel, Citellus richardsoni (Figure 1). During the past …

Assessing Impacts of Winter-hay Feeding on Soil and Forage Nutrient Dynamics in a Rotationally-Grazed Pasture System in Arkansas
… of nutrients beyond those required to grow the forage needed for animal consumption. At the same time, a large amount of nutrients is recycled back to pasture systems directly from hay fed to cattle. This study evaluated the effects of winter-feeding hay management on soil fertility and forage …

Determination of tannin levels in multi-purpose Kenyan trees and fodder crops, their variation and effect on protein digestibility in ruminants
… therefore multipurpose fodder trees (MPT) and forage crops are advocated as the alternative supplements, because they are inexpensive, able to provide green forage even in dry season and have high protein content. These trees have tannins whose levels, seasonal and altitude distribution have …

Assessment of stockpiling methods to increase late summer and early fall forage biomass
As one of the major forage crops of the United States management programs to optimize stockpiled tall fescue (Festuca arundinacea Schreb.) can potentially increase livestock profitability. This study consists of two experiments designed to assess different aspects of summer stockpiling. Experiment …

Evaluation of the Persistence of Grazing Alfalfa Varieties
… legume, and is one of the most nutritional forage crops available. It is proposed that alfalfa was cultivated 4000 to 5000 years ago and produces the most protein per acre of any forage crop. Live weight gains for beef cattle grazing alfalfa average 230 to 360 kg ha-1. There is no cheaper …

Effects of Excessive Soil Phosphorus Accumulation on Loblolly Pine (Pinus taeda L.) Seedlings
… to pastures as a source of nitrogen (N) for forage crops. After many years of repeated poultry litter application, soils can accumulate extremely high extractable phosphorus (P) concentrations, sometimes over 1000 mg kg<sup>-1 </sup>of plant available P. Landowners report the conversion of …

Satellite image classification and spatial analysis of agricultural areas for land cover mapping of grizzly bear habitat
… in agricultural areas were found in grasses / forage crops 77% of the time, with small grains and bare soil / fallow fields making up the rest of the visited land-cover. Locational data for 8 bears were examined in an area southwest of Calgary, Alberta. The 4494 km² study area was divided into …

Annual forage cropping-systems for midwestern ruminant livestock production
<p>Annual forage cropping systems are a vital aspect of livestock forage production. One area where this production system can be enhanced is the integration of novel annual forages into conventional cropping systems. Two separate projects were conducted to investigate alternative forage options in …

Response of alfalfa to foliar applications of long-chain fatty acids or seed treatments with Chevron XE-1019
Forage crops grown in many parts of the Appalachian region are restricted in yields as a consequence of shallow soils, low levels of essential nutrients, toxic levels of aluminum, and low pH. Therefore, the successful growth of alfalfa in these regions is dependent on either changing existing …

Intercropping for food, fiber, and fuel on pine plantations in Virginia and North Carolina
… as a management approach where two or more crops are planted on the same forested site simultaneously. The advantages of applying this concept on young pine plantations in the south can increase site utilization, reduce weed competition, provide annual or semi-annual revenues early in the …

Industrial hemp agronomic management for grain, fiber, and forage
… fertility rates, and the potential of hemp as a forage crop. A three-year study was conducted in Blacksburg and Orange of Virginia State to assess the effects of tillage management and production systems (e.g., seed, dual, and fiber) on hemp establishment and productivity. Two cultivars, Joey (a …
