(2012): Effects of silage-free feeding on the performance of dairy cows in Tyrol
ZUCHTUNGSKUNDE. 2012; 84(2): 191-198.

Roughly 15% of the milk produced in Austria comes from farms without silage production and feeding. In this paper, lactation performances of cows kept on farms with silage feeding were compared with the lactation performances of cows kept on farms without silage feeding. All lactations completed in the province of Tyrol between 2004 and 2006 were included in the analyses. 44,729 lactations were based on a silage-free ration, and 77,095 lactations were recorded where silage was included in the ration. On average, the standard lactation performance with the use of silage was 6,281 kg, whereas the silage-free feeding resulted in 5,877 kg of milk (a difference of 404 kg; P < 0.001). The inclusion of silage led to a higher milk fat content (4.10 vs. 4.03%; P < 0.001) and a reduced lactose content (4.81 vs. 4.83%; P < 0.001). On the other hand, silage-free feeding in Simmental cows resulted in a higher milk protein content (3.35 vs. 3.32%; P < 0.001) and a higher lactose content (4.82 vs. 4.79%; P < 0.001). The milk urea content was reduced when silage was fed (21.3 vs. 21.9 mg/dl; P < 0.001). Milk from Simmental cows fed with silage had a greater somatic cell count (164,000 vs. 134,000 somatic cells/ml; P < 0.001). Cows kept on farms without silage feeding had a shorter calving interval (384 vs. 394 days; P < 0.001).
