[Low milk fat syndrome in dairy cows. Field trial with potential fat content increasing substances (author's transl)].

In cases of low milk fat syndrome in dairy cows, in which no cause-factor could be found, a mixture of different potential fat content increasing substances was added to the feed, one group was fed 50 g NaHCO-3, 50 g MgO, 50 g urea and 100 g sodium bentonite mixed into 250 g of carrier per cow per day, while another group was fed the same mixture with sodium bentonite excluded. A third group was used as an untreated control. Fat content and milk yield were not positively influenced by these additives. The inclusion of sodium bentonite even seemed to result in a certain decrease of milk yield. In another similar trial, 150 g NaHCO-3 and 100 g MgO were fed, mixed into 250 g of carrier per cow per day. This improved the milk fat content when compared to an untreated control group. The increase was not significant. The milk yield, however, was significantly influenced by the addition. The yield increase in this trial was calculated to be approx. 2.0 kilos FCM per cow per day.

The effect of different calcium doses in milk fever therapy. A comparative internordic field study.

In an internordic field study of the effect of the Ca dose (6, 9 and 12 g) on the therapeutic result in parturient paresis, considerably better results were recorded in Finland than in the other countries at all dose levels. In Finland a full effect was obtained with 6 g, while in all others 9 g Ca yielded a significantly better result than 6 g. Raising of the dose to 12 g produced no improvement. There was a significant difference in therapeutic results between the two Finnish breeds. A larger number of fatal cases was recorded among paretic cows with plasma Ca greater then 8.0 mg/100 ml.
