The effect of inorganic and organic form of zinc on digestibility of nutrients dairy cows in three stages of reproductive cycle

Popis výsledku v původním jazyce

The aim of our experiment was to compare the effect of feeding inorganic and organic forms of zinc in premix on the coefficient of digestibility of nutrients in the feeding ration for cows in three stages of reproductive cycle -- 14 day before calving and 30 day and 60 day after calving. The experiment was carried out on 19 Holstein cows that were divided into two groups. A control group of nine cows designated as "Inorganic zinc form" (IZF) was fed a diet supplemented with mineral premix containing inorganic form of zinc (ZnO). An experimental group of ten cows designated as "Organic zinc form" (OZF) had zinc oxide replaced with zinc fixed to methionine (Khei-chelate Zn powder 15% by Kheiron). The experiment was divided into three periods - the firstperiod lasted from 14th day before calving until 2nd day after calving, the second period lasted from 3rd day to 30th day after calving and the third period lasted from 31st day to 60th day after calving. Cows were fed the diet based on m
