Another benefit of brassicas is they are fairly tolerant of dry conditions and hold up well to heavy grazing. Jillian Bainard, of AAFC Swift Current, noted that cattle were less likely to graze brassicas during her ongoing study into grazing intercrops. Forage brassicas can potentially be used to extend the grazing season into the fall for beef cattle operations, thereby reducing input costs. They reach near maximum production levels in 80 to 90 days. In addition, the digestibility of the forage remains high over a relatively longer period than perennial crops. Avoid abrupt changes from dry summer pastures to lush Brassica pastures. In addition to their benefits to cattle, brassicas — with large fibrous roots — can also help old, compacted pastures.

Swedes are only recommended for cattle with fully mature teeth and are not suitable for broken mouthed sheep. Although higher-CP forages are generally desired by producers, levels this far in excess of dietary … Nitrate poisoning has been documented from excessive nitrogen fertilization. Brassicas are high quality forage if harvested before heading. As previously mentioned, forage brassicas can be grown to supplement perennial cool-season pastures in August and September or to extend the grazing season in November and December. Plant in the early fall for single late fall or early winter grazing, similar to stockpiling fescue. Nutritional quality of brassicas is very solid. 0000005552 00000 n Forage brassicas are sown as supplementary feed for animals, typically during periods when pasture growth is limited or quality is poor. ~5ƿ,=�5xm��d9 �!�=��M��b�#[6F6�l�ll��ز1��ecdc���Ɩ��M_v�����։��s��b�Z�v���!��dO���e��` ��} endstream endobj 712 0 obj <> endobj 713 0 obj <>stream 0000006624 00000 n This makes great grazing for any class of livestock.

Straw or hay should be available ad lib in the paddock at all times to assist with digestion. In the first instance, brassicas would be planted in May or early June because spring rains will help ensure production for August and September grazing (Figure 1). A last note, do not grow brassicas in the same field for more than two consecutive years as diseases will build up to reduce stand and yield. This practice can extend the grazing period well into late winter. Hall says, for example, that the typical seasonal stocking rate on a thriving brassica crop in Pennsylvania is about 160 cow (or 1,500 ewe) grazing days per acre. Brassicas feature in most polycrop seed mixes on the market, but feeding cattle on those mixes may require some extra consideration. ����L~6���Qdz�G������d���뼐_���J~o�[���3��1�O��@?~s� Mary & Diarmuid answer some questions on grazing brassicas like kale, hybrid brassica & forage rape - Duration: 3:13.

Incorporating Brassicas Into Your Grazing System; Incorporating Brassicas Into Your Grazing System. Straw or hay should be available ad lib in the paddock at all times to assist with digestion. It makes little sense to take out a productive perennial pasture for an annual forage. The roots of turnips and kale usually have 10-14% crude protein and 80-85% digestibility. Brassicas can provide grazing at any time during the summer or fall depending on seeding date. While high in crude protein and energy, Brassica crops, like all grazing crops and lush pastures, are low in fibre content. For example, over a dry autumn raphanobrassica provided more than 3,000 sheep grazing days compared to forage rape, which provided 1,200 sheep grazing days.” Other considerations Accumulation of calcium and potassium can reduce the availability of magnesium to animals, resulting in hypomagnesemia or “grass tetany”.
