Behoud van melkproductie en diergezondheid bij verlaging van de P-output op dierniveau door optimalisering van voedingsadviezen

By Harm Stokman

Abstract

In this feeding experiment we have looked to the effects of Phosphorus gifts and structure variation on the milkproduction of high productive cows on the top of their lactation. We made 4 groups of each 12 cows and have feeded 2 different levels of Phosphorus and 2 different levels of structure.During a period of 10 weeks we took a lot of samples(blood,bone etc) and we checked the feed intake and milkproduction/health of the cows.When we look at the results we see the best P-values in the blood.There was some influence on milkproduction and feed intake but we haven't seen any health problems.The conclusion is that it will be possible to feed lower Phosphorus in the ration in the future
