 ch Proposal\n\nFeeding unbalanced forages that are high in nitrogen (N) an
 d low in carbohydrates to ruminants can be detrimental for agricultural pr
 oducers\, both environmentally and economically. Nutritionally unbalanced 
 forages are associated with potentially high N losses as the rumen microbi
 ome may be unable to assimilate efficiently the N present in forages if th
 ere is insufficient energy provided by carbohydrates. Therefore\, to impro
 ve N efficiency\, it is necessary to balance the amount and the availabili
 ty in the rumen of both carbohydrates and protein fractions of forage fed 
 to ruminants. Two ratios of carbohydrates to proteins are predominantly us
 ed to assess this balance: i) water-soluble carbohydrates over crude prote
 ins\, and ii) mono and oligo-saccharides + starch over non-protein N + rap
 idly degradable proteins. Increasing these ratios in forages will allow fo
 r a better N utilization by the microbial population of the rumen. A proje
 ct has been established at three contrasting sites in Canada to assess if 
 changes in forage species used in mixtures can be a mean of increasing car
 bohydrate to protein ratios. The experiment contains twenty-one different 
 treatments composed of combinations of three different forage legumes (alf
 alfa\, red clover\, and birdsfoot trefoil) in different proportions and th
 ree different grass treatments (timothy\, tall fescue\, or no grass). The 
 above ratios along with other nutritive attributes will be measured to ide
 ntify mixtures with the highest N efficiency potential.\n\nTO PARTICIPATE.
