[The effect of feeding corn silage juices on selected indicators of metabolism in dairy cows given feed containing various proportions of silage and hay].
In farm production conditions two comparative trials lasting 58 and 128 days were carried out. Acidogenic exposure to acids of silage juices, silage and haylage (lactic acid, acetic and butyric acids) in feed ration ranged from 0.33 to 2.85 mol per 100 kg live weight. It was proved that it was possible to include 9 to 10 litres of silage juices in feed ration under the condition that the total daily intake would not exceed 1.94 mol of acids per 100 kg live weight. This supplement of silage juices increased milk production. Higher amount of acid (2.65 and 2.85 mol) resulted in acidogenic and ketogenic type of silage juice enriched feed ration, which caused a more rapid decrease of lactation curve in dairy cows fed this feed ration than in those in the control group.
