Description

Forage grasses and legumes are a main component of livestock diets in winter cold zones, There are over 130 million ha of grassland in this zone and there is a large, undeveloped land base in fringe areas suitable for forage production. Regulations on land ownership and use hamper efficient development of forage-based farming systems in some regions. The short growing season Ii mils the grassland farming in the winter cold zones. The winter season is long and cold temperatures, freezing and thawing, and diseases' exert severe stress on overwintering forage plants. The development of persistent cultivars is essential for sustained production, particularly in the fringe areas with marginal growing season. The seasonality of dry matter production is a result of high growth rates in early summer and low dry matter accumulation in late summer and autumn. Innovative management practices and cultivars with improved regrowth capacity are necessary to overcome such skewed production pattern and to extend effective grazing season. Improved pastu1e production is an important factor in reducing costs in livestock operations and remaining competitive. It is suggested that applying available technology would increase forage and pasture productivity and reduce dependence on stored feeds, thus improving profitability of small producers in particular. Reducing nutrient losses during harvesting, storage and feeding is essential for improved production efficiency during confinement feeding. The development of low cost and labour-saving methods of ensiling is critical for .improved efficiency and profitability of forage-based enterprises. Livestock industries must respond to consumer preferences for low fat and low cholesterol foods. Research and development of entire production systems is emphasised for developing viable enterprises.

Factors Required to Sustain Pastoral Farming Systems and Forage Supply in Winter Cold Zones

Forage grasses and legumes are a main component of livestock diets in winter cold zones, There are over 130 million ha of grassland in this zone and there is a large, undeveloped land base in fringe areas suitable for forage production.
