A new Queensland-bred forage oat variety, Genie, offers a new grazing option and significant million-dollar benefits to livestock producers. Minister for Primary Industries and Fisheries, Tim Mulherin, said the breeding program demonstrated how government and industry could work together to benefit Australian farmers. Mr Mulherin said funding and field support from Heritage Seeds and Meat and Livestock Australia were integral to the oat breeding program. In launching the...
A study by the Agricultural Research Service (ARS) and the University of North Dakota lays a foundation for eventually allowing ranchers to get Web-based information on the quality and quantity of forage plants in their fields. Ranchers could use this information to determine stocking rates, as well as how much carbon is stored in their forage plants. Scientists Rebecca Phillips and Ofer Beeri have developed a way to measure rangeland forage plant yields in pounds per acre, and their...
Recent rains across northern and central Indiana give producers a small window to accomplish forage management related tasks, said a Purdue University expert. One of those tasks is seeding crops. Producers must be cognizant of the time of season they seed in, said Keith Johnson, Purdue Extension forage specialist. “It’s too late to feel good about seeding alfalfa in the very northern parts of the state, but if you have fallow land and received rainfall, there’s still time to...
EU ministers and national experts are due to approve a genetically modified (GMO) sugar beet variety this month despite a long running dispute over the use of biotechnology. Officials say around 10 GMO products, mostly maize types but also cotton, soybeans and a high-starch potato, are scheduled for discussion at various levels of the EU in the next few months. Although the bloc's member governments clash consistently over GMOs, never reaching the required majority under its...
The practice of making sweet ensilage, the favoured method of the early protagonists, involved allowing the forage in the silo to heat to a temperature above 160 oF (71 oC; Fry, 1885). This practice, which would today be met with horror by the farming community, was promoted well into the 20th century by respected bodies such as the Ministry of Agriculture and Fisheries (Anon., 1926). Sweet ensilage (with its high level of undesirable volatile fatty acids) is probably also...
In temperate regions of the world forage legumes growing in spring and summer are frequently stored as silage for delayed use during periods of feed shortage. However, in contrast with most grass species, they often undergo fermentation pathways that are detrimental from a nutritional perspective. In the ensilage process there is an early and short aerobic phase followed by a major anaerobic phase during storage time, and finally a new exposure to air when feeding the ensiled...
The points of the silage triangle are represented by persons responsible for (1) the animals, (2) the forage, and (3) the harvesting/ensiling processes. In some beef and dairy operations, one person is responsible for all three points. But in many instances, both growing the silage crop and harvesting and ensiling the crop are done completely on a contract basis, creating a situation where a different person is at each point of the triangle. When communication between the points of the...
Biotal forage inoculants manufactured by Lallemand Animal Nutrition, Milwaukee, Wis., feature a new formula for improved stability.
This new formulation ensures the product stays viable when mixed with water for application. Once the bacteria in inoculants have been re-activated by mixing with water they begin to produce acids as they do when they are applied to forages. In many inoculants this is uncontrolled and the bacteria can die off quickly from the effects if the acids. Biotal's...
The primary goal of making silage is to maximize the preservation of original nutrients in the forage crop for feeding at a later date. Unfortunately, fermentation in the silo is a very uncontrolled process usually leading to less than optimal preservation of nutrients. In order to assist in the fermentation process, various silage additives have been used to improve nutrient and energy recovery, often with subsequent improvements in animal performance. This review will focus on some practical...
Grass silage is, and will remain, the basal forage for the majority of beef and dairy cattle in Ireland, the United Kingdom, Northwestern Europe and the Nordic countries during the winter indoor feeding period. Currently in Ireland and the UK 22 and 50 million tonnes, respectively, are ensiled annually (Wilkinson and Stark, 1992), half of which are treated with an additive. Most silage in Ireland and the UK is harvested by contractor using selfpropelled precision-chop forage harvesters...
In South Africa summer rainfall occurs in the northern parts and winter rainfall in the southern parts. In some areas of the Southern Cape, rainfall varies from 750 to 1200 mm annually and rain occurs throughout the year. Even in this area farmers need to irrigate pastures as total rainfall and rain distribution vary considerably from year to year. To achieve the continuous supply of high quality roughage that forms the basis of profitable dairy farming, crops or grasses must...
