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.
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.
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.

Editor's Notes
Потребление корма В общей сложности 12% по сравнению с 0,4% корма осталось в течение последней недели сухостойного периода, что составляет соответственно 12 коров, принимавших X-Zelit, и 3 контрольные коровы. Статистический анализ не выполнялся.
