The document describes trials of a supplement called X-ZELIT given to dairy cows before and after calving on 4 farms. The supplement was mixed in feed or top-dressed and aimed to reduce health issues after calving like milk fever, displaced abomasum, and metritis. Results showed reductions in these issues on 3 of the farms and no problems with cow consumption. General observations found the supplement helped minimize health issues but did not clearly increase milk production, and it was difficult to administer to cows outside. Most farmers planned to continue using the supplement.
A study was conducted to test the effects of X-Zelit® supplementation on non-problem dairy herds. Cows were assigned to either receive X-Zelit® or be part of the control group. Results showed cows receiving X-Zelit® had slightly higher milk yields and lower somatic cell counts, particularly for multiparous cows. X-Zelit® supplementation also reduced the occurrence of metritis in third-lactation or greater cows.
1) The document discusses data from several UK farms on the impact of feeding cows X-Zelit® on common health issues around calving like milk fever, metritis, retained placenta, and left displaced abomasum.
2) The farms reported reductions in the rates of these issues after adopting X-Zelit®, for example one farm reduced milk fever cases from 32% to 0% of cows calved.
3) The potential savings from reductions in treatment costs for these issues on a hypothetical farm of 100 cows ranged from hundreds to thousands of pounds per year.

Falköping, Schweden
• Im Frühjahr und Sommer wurde eine kleine Studie auf dem
Hof Duvereds Lantbruk durchgeführt, bei der X-Zelit und sein
Einfluss auf das Auftreten von Milchfieber getestet wurde.
• Bei insgesamt 21 Kühen wurde vor dem Kalben X-Zelit 10-20
Tage zum Futter zugegeben. Anschließend wurden die
Ergebnisse mit den 21 Kühen verglichen, die früher gekalbt
hatten und daher kein X-Zelit erhielten. Erstgebärende
wurden ausgeschlossen.

Anmerkungen
* Hierbei handelte es sich um eine Sechstgebärende, die nach dem Kalben paretisch erschien; es lag jedoch
ein nach links verlagerter Labmagen bei Durchfall bis zum Kalben vor. Die Kuh erholte sich danach.
*** Einschließlich zweier zwillingskalbender Tiere, die wegen der geringfügig kürzeren Trächtigkeit nur 5
bzw. 8 Tage X-Zelit erhielten.
**** Eine Kuh mit Verdacht auf Festliegen. Die Kuh erholte sich.
