Gunnar Pettersson, tidigare försöksledare, säger att man efter ca 1 års tester föredrar att använda Juvelit-micro till sina robotar då det visat sig att spenkonditionen, som alltid varit utmärkt på Kungsängen, blivit ännu bättre med Juvelit-micro!
It is important for Topro Animal Health and our partners that we support the Topro products with results of field trials. We know the products work from practice use, but what do we actually measure? The aim of this trial is to measure the effect of preventive treatment with Topro Calcium boluses on health and milk yield of dairy cows. The question arose because subclinical milk fever is still a common problem in cows around the calving.
Research method: 141 dairy cows participated in the study (1 control and 2 test groups). The study was conducted on 9 different dairy farms in Gelderland and Overijssel, The Netherlands. The dairy farmers were using automatic milking systems and the control and test groups experienced the same conditions on the individual farms. The test group-1 received 1 treatment, 1 day before calving. Test group-2 received 2 treatments, 1 day before and 1 day after calving (1 treatment = 2 boluses = 40 g pure calcium). This study focused in particular on rumination activity and milk production in cows around calving.

The aim of this trial is to measure the repeated effects (of trial TP0L001-21) of preventive treatments with a Topro Dry bolus on the health and milk yield of dairy cows. The previous trial showed good results, but can this be measured and confirmed again?
110 dairy cows participated in the study (57 in the test group and 53 in the control group) at 8 dairy farms in Gelderland and Overijssel, The Netherlands. These dairy farms did not participate in the previous field trial. The dairy farmers were using automatic milking systems. The test group received 1 Topro Dry bolus on the first day of the dry period.
This research has repeatedly shown that the Topro Dry bolus significantly increases the feed intake activity and rumination activity. In this study we can conclude that the Topro Dry bolus leads to a higher milk yield in the critical weeks of lactation. It is plausible that a higher feed intake and rumination activity leads to higher milk production. More feed intake, on the other hand, has a positive effect on the cow’s energy supply, which can reduce the risk of transition diseases (such as milk fever and subclinical milk fever). Optimalization of feed intake in the first weeks of lactation is very important for a good start of the dairy cow. This will ultimately also contribute to a longer lifespan. * ANOVA test P ≤ 0,05
