Research Progress on Supplementary Feeding of Grazing Livestock in Cold Season
With an increase in grazing livestock numbers,grassland degradation poses an enormous threat to human,which continuously sharpen the forage-livestock-people contradiction.The four seasons are not distinct in alpine meadow,but only the cold and warm seasons;the standing forage varies greatly with the season.Supplementary feeding in cold season can not only improve livestock body weight and morality,but also alleviate grazing pressure,so as to keep the sustainable development of grass-based livestock husbandry.In this review,we summarized the feed types,the effects of supplementary feeding on the growth and reproductive performance of livestock,as well as the ecologic function of grasslands.It would provide a reference for further research.
