Description
Brassica pekinensis X B. rapa var. tyfon was evaluated for its potential for extending the grazing season and utilization for finishing lambs. Tyfon was seeded without tillage in mid-July and grazing was initiated in each of two years about 70 days after seeding with lambs which had previously grazed clover-grass. A similar group was placed on a balanced ration of hay and grain. Tyfon maintained high quality throughout the grazing period, which was 45 days in 1983 and 68 days in 1984. Lambs gained an average 214 and 249 g day-1 in 1983 and 1984, respectively, on tyfon, while lambs on hay and grain gained 195 and 186 g day-1. Quality of animal carcasses from both rations was equivalent. Tyfon shows good potential for incorporation into a grazing system and utilization for late-season lamb fattening, while minimizing cost of production.
