Nutrients digestibility of foodstuff in cow's feeding using complete feed

We′ve studied a complete feed influence on digestibility, nutrients accessibility, nitrogen, calcium, phosphor balance in daily diet of fresh cows. Experimental group of fresh cows digested dry matter better then controlled group by 0,78 %, crude protein - by 0,77 %, crude fat - by 3,98 %, crude cellulose - by 3,14 %, extract substances without nitrous - by 4,45 %. Calcium and phosphor balance is positive in experimental group. Moreover a percentage of using them is higher: calcium - 36 %, phosphor - 42%.
