X-Zelit improved production in Hungary

The test included 48 cows in the X-Zelit group, and 80 cows in the control group. Blood samples were drawn when cows entered the close-up group (approx. two weeks before calving), at calving, and on the third and fifth day after calving. The samples were analysed for calcium, phosphorous and magnesium. The results showed that calcium levels in the X-Zelit group increased around calving, and that the animals prevented subclinical hypocalcaemia. Furthermore, the blood samples revealed reduced phosphorous levels, which corresponds entirely to the outcome of previously conducted tests. Low phosphorous values are important to obtaining an optimum effect of X-Zelit and are also indicative of the cows having consumed the expected amount of X-Zelit.

A comparison was made of the number of diseases during early lactation. A significantly reduced frequency of clinical mastitis was observed, with the frequency in the X-Zelit group reduced to 25% compared to the control group. Prevalence of lameness and metritis was slightly reduced Retained placenta was reduced from 21% to 14.6%, and the number of cows culled within the first milk control had decreased.
A comparison was made of the milk yield at the first milk control after calving. In the X-Zelit group, it was 30.6 ECM, and 29.4 ECM in the control group.

In conclusion, X-Zelit reduces metritis and mastitis, in particular. The milk yield in the X-Zelit group exceeded that of the control group by 1.2 kg.
