Short-season forages planted in late summer can be sources of highly digestible fiber in ruminant livestock rations. There are several excellent forage options that can be considered for no-till or conventional tillage plantings in the late summer or early fall planting window. These forages can be a planned component of the overall forage production plan. They can be utilized on land that would otherwise sit idle until next spring, such as following wheat or an early corn silage harvest.
Oat or Spring Triticale silage
These cereal forages can be planted for silage beginning the last week of July and into early September. Dry matter yields of 1.5 to 3 tons per acre (about 5 to 5.5 tons at 30 to 35% DM) of chopped silage are possible if planted in late July to early August. Harvesting between late boot, or early heading, will optimize quality. Yields will be lower for plantings made in early September, in which case late autumn grazing would be a more viable option.
The potential feed value of oat silage can be similar to mid-bloom alfalfa. As a grass, maximum inclusion rates in diets for animals with high nutritional demand (e.g. lactating cows) are less than those for alfalfa, but it is a very acceptable feed.
Spring Triticale is the biotype of the hybrid cross between cereal rye and wheat (there is also a winter biotype that acts like winter wheat). In our research, oat averaged slightly higher fall yields than spring triticale, but this varied across years. If cut at the proper maturity, spring triticale forage has a higher feed value than oat, similar to early-bloom alfalfa. Seed cost for spring triticale is usually higher than oat, but it is later maturing than oat or barley and will maintain its forage quality for an extended harvest window. Continue reading
