DD status as heifer


Treatment for DD in first lactation Conception rate after first insemination


The presence of DD in young- stock is associat- ed with an in- creased DD prevalence in the lactation stage.


No DD in the rearing period 13.7% 42.3%


One DD treatment in the rearing period Several treatments for DD in the rearing period 45.6% 36.3%


67.6% 29.0%


tion rate compared to cows with DD in the rearing period. The conception rate after the first insemination was monitored again in three groups: heifers with no DD in the rearing peri- od, one DD treatment in the rearing period and several DD treatments in the rearing period. The results were 42.3%, 36.3% and 29.0%, respectively (Table 1) (Gomez et al., 2015), which confirms the importance of DD control in youngstock once again.


Previous studies have shown that first-lactation cows are at greatest risk of DD, which shows the importance of con- trolling DD in this specific group (Rodriguez-Lainz et al., 1999; Somers et al., 2005).

Intra Hoof-fit Spray – some advantages: •


Ready-to-use – no mixing required. • • •


• •


Early lameness detection - more focus on hooves with weekly spraying sessions.


100% clean solution – each hoof gets product uncontaminated by the hooves of other cows.


Environmentally friendly – good adhesion helps reduce product dosage and minimise run-off on the floor.


Safe to use – no formalin, antibiotics, acids, or offensive smell.


Easy product detection – the stickiness and the green color ensure that no hoof is accidentally omitted.


• Optimum viscosity – the good flowability prevents blockages of the spraying nozzle.

The green color of Intra Hoof-fit Spray ensures that no hoof is accidentally omitted.


Healthy hooves in youngstock It is often hypothesised that youngstock may act as a DD res- ervoir, in which the causative agent can be transmitted to lac- tating cattle after calving. By implementing hoof health pro- tocols that prevent DD infections in youngstock, major problems may be averted in the lactation stage, including chronic cases of DD. As footbathing is often not a practical application for young- stock, alternative prevention measurements are needed. Indi- vidual spraying with a low-pressure sprayer or an automatic sprayer is easier, more practical and gaining in popularity compared to footbaths. Intra Hoof-fit Spray has been special- ly developed as a ready-to-use rinsing liquid for spot-spray- ing on the hoof. The strong adhesion provides a long contact time (over nine hours) and reduces waste on the floor or in the manure pit (Roijackers et al., 2019). The weekly use of Intra Hoof-fit Spray maintains, supports and promotes healthy hooves and dermis.
