VERFAHREN ZUR VERBESSERUNG DER MILCHLEISTUNG VON KUEHEN

摘要

Method for qualitatively and quantitatively improving milk output in cows involves feeding the cows during the puerperal phase with 150-600 g protein/day in addn. to the usual fodder, the additional protein being administered as a feed supplement in the form of protein cpds. protected against premature degradation in the rumen. The supplementary protein overcomes the protein deficiency experienced by high-yield milk cows during the puerperal phase (10 weeks following calving or onset of lactation) attributed to increased energy requirement at this time accompanied by poor absorption of nutrients. Protection of the protein against degradation by rmen bacteria ensured that all of the administered protein is physiologically available to the cow. The protein content of the milk from cows fed the supplementary protein is up to 15% higher than that of cows given no protein supplement. In addn. the supplementary protein prevents reproduction disorders and other disorders that can otherwise occur with high-yield dairy cattle.
