متن کاملPerformance of lactating dairy cows fed either alfalfa silage or alfalfa hay as the sole forage.
Alfalfa was harvested from alternate windrows as 40% DM silage or hay in small rectangular bales and fed in two 12-wk 4 x 4 Latin square trials, each with 20 multiparous lactating cows (4 with ruminal cannulas). Diets contained (DM basis) 69 (trial 1) or 66% (trial 2) alfalfa, 26 to 33% high moisture corn, 1.3% minerals and vitamins, and about 1.6 Mcal of NEL/kg of DM. In trial 1, second-cuttin...
متن کاملChanging Forage Quality Testing for Alfalfa Hay Markets:
There is ample evidence that our current fiber-based marketing system is inadequate in predicting some of the most important features of alfalfa and other hay products. Worse, our current system has the potential for abuses. Seven of these abuses are described here. One key misuse is the over-emphasis of small differences in fiber concentration (as translated to TDN or RFV), while ignoring impo...
