- Abstract
In this project feed intake and milk yield of barn fed cows were compared with those of cows who had access to pasture for 6 hours per day. Therefore, 16 cows of Holstein Friesian and dual-purpose Simmental breed were equally split into two groups, considering milk yield, breed and the number of lactations. The barn fed dairy cows were kept indoors the whole time of the project (from April 19th to October 3rd) and were fed with grass silage ad libitum, 3.8 kg DM hay per day and an energy and protein concentrate according to milk yield. The pasture group was offered grass silage ad libitum and 2.0 kg DM hay every day in the evening. In comparison to the indoor group, concentrate offering was more restrictive. After the morning milking, the pasture group had access to a continuous grazed pasture (growth height 4.0-4.5 cm, Rising Plate Pasture Meter). Milk yield and indoor feed intake were observed on individual level in both groups. The feed intake of pasture was calculated by recommended energy supply. Results showed no differences in total feed intake per day (17.0 kg DM) between the two groups. The pasture group had a pasture intake of 7.5 kg DM per day and showed a second milk-peak during the lactation, as well as a better persistence until the end of the grazing period. This resulted in a significantly higher milk yield in the pasture group (3,756 towards 2,975 kg ECM/cow). Milk fat contents did not differ between the two groups, but the contents of milk protein and milk urea were significantly higher in the pasture group (2.94 across from 3.19% and 19 towards 32 mg/100 ml). There were no differences in the concentrate input per kg ECM (135 g and 134 g/kg ECM).
