Forage soybeans are not normally recommended as an emergency forage. Forage soybean production has a steep learning curve. Successful producers started with a small acreage and took several years to learn how to manage this crop. Whole unroasted soybean seeds pose a risk of ammonia toxicity. Limit to 2-4 lbs/head/day. Protein exceeding animal demand will require feed energy for excretion….
Christine O'Reilly July 14, 2021 232 Comments Off on Grazing Livestock and Forage Palatability: How They Go Hand in HandThis article was written by Breann Saulnier, OMAFRA Grazing Livestock Assistant You may look out into a pasture and see an abundance of tall, delicious-looking grass for livestock to graze but this is not necessarily what the livestock see. The amount of forage available for grazing is the portion of plant material that the animal chooses to eat, not the…
Regrowth rates of hay fields following a cut and pastures following a grazing event is dependent on rainfall. Areas that received below-average rainfall may experience slower regrowth. Producers looking to buy or sell hay are encouraged to check out the new and improved Ontario Hay Listings website Southwest According to AAFC, most of the area south of Highway 7 received…
Many management decisions affect hay quality. After deciding when to cut, the next big decision is about the moisture content. Accurately timing how long to let the crop wilt when harvesting a forage crop will help ensure that it stores well. It either needs to have enough moisture to ferment correctly (silage/haylage or baleage systems), or low enough moisture…
Rain events across the province have interrupted a dry spring. While the water is welcome, the 5-7 days after a rain that ends a severe dry period increases the risk of nitrates in forage crops! Nitrates are of concern because they can increase silo gas production and cause nitrate poisoning in livestock. Silo Gas Silo gas (nitrogen dioxide, N2O) is produced…
Christine O'Reilly May 13, 2021 3828 Comments Off on Slowing down the rotation protects pasture yieldCo-written by James Byrne, OMAFRA Beef Cattle Specialist Grass doesn’t just happen. Maximizing pasture yield requires management, and one of the most important decisions a manager can make is to give their grass enough time to fully recover after being grazed. Pastures have fully recovered from a grazing event when the grass plants have 3-4 new leaves. At this stage…
Winter of 2020-2021 was mild. Although snow cover was less than normal, there were relatively few thaws. A rapid thaw in early March melted most of the snow. The warm temperatures persisted for a few days, allowing perennial forages to break dormancy. Dry conditions throughout March with warm days and cool nights provided a window to frost seed that lasted…
Frost seeding is a popular way to renovate an existing forage stand and is most effective in fields where patches of bare soil at least the size of a loonie are visible. With spring around the corner, many producers have questions about how to best use this technique to improve their hay fields and pastures. When can I frost seed…
Silage corn is grown to provide energy and fibre in a ration. It has very high yield potential. In addition to breaking corn rootworm lifecycles, alternatives to silage corn need to offer similar yield and nutritional value (Table 1). Producers should consult a livestock nutritionist to ensure rations are properly balanced. Table 1. Typical nutritional quality and yield of some annual forage…
Christine O'Reilly January 11, 2021 823 Comments Off on What is the true cost of Alfalfa Snout Beetle on your farm?This article was written by Dr. Elson Shields, Department of Entomology, Cornell University, Ithaca, NY **A note from Christine: Alfalfa snout beetle is an invasive species. A 2008 survey confirmed its presence in Leeds & Grenville, Prescott & Russell, and Stormont, Dundas & Glengarry counties. At that time, over 150 km2 were infested. Dr. Shield’s research on biocontrol nematodes was…
Christine O'Reilly January 6, 2021 810 Comments Off on Taking Root: Management Options for Bt-Resistant Corn Rootworm on Ontario FarmsThis webinar features OMAFRA specialists who provided an update on Bt-resistant corn rootworm, the impact on cropping systems and feed supplies, mitigation strategies to reduce the impact of Bt corn rootworm resistance, and alternative feeding options. While this webinar is open to anyone, it is geared towards cattle producers (dairy and beef). The webinar aired December 8, 2020. Speakers include…
Photo: It is impossible to tell by looking at frost-damaged sorghum-sudangrass what the prussic acid levels may be. Silage Corn In fields where rootworm Bt hybrids have been used for three or more consecutive years, resistance among corn rootworm populations is suspected. Producers can no longer rely solely on Bt rootworm hybrids for protection against rootworm injury. See the 2020 Canadian…
Caution! Members of the sorghum family – sorghum, sudangrass, and hybrid sorghum-sudangrass – contain dhurrin, a glucoside that breaks down to release hydrocyanic acid, also known as prussic acid (hydrogen cyanide, HCN). A sudden disruption of growth such as frost, drought or cutting, causes prussic acid to be released inside the plant at a more rapid rate. High prussic acid…
Christine O'Reilly September 21, 2020 780 Comments Off on Managing Jointing and Non-Jointing GrassesChristine O’Reilly, Forage and Grazing Specialist, OMAFRA Grass doesn’t just happen and not all species grow the same way. Understanding how different grass species grow enables producers to make good management decisions that maximize forage production in their hay fields and pastures. Jointing and non-jointing grasses respond differently to cutting, which directly affects productivity and persistence. In an established stand,…

Silage corn growers should check fields for rootworm resistance to Bt hybrids Scouting for corn rootworm injury in silage fields is important to detect potential resistance to rootworm Bt traits and…
