Bolused dairy herd achieves uplift in milk yield

A dairy producer with 1200 milking cows says he has seen an uplift in daily milk yield of one litre per cow after bolusing his autumn-calving herd.

 

 

Ed Dale, who farms in partnership with his parents and wife in Cheshire, says high iron content in drinking water had been restricting copper intakes in the cows.

“We got an instant response and within a couple of weeks they looked different animals altogether, really sharp and a lot happier.’’
And the bolus has improved fertility in the spring-calving cows too. “We have gone from well over 20% empty after 10 to 12 weeks to well under 20% empty. Perhaps that’s not just the bolus but I’m sure it has made a big contribution,’’ says Mr Dale.
“We gave the cows an Animax bolus and within a week to 10 days the milk had actually lifted by one litre a cow and we think that the bolus is probably the reason why,’’ says Mr Dale.
 

He also trialled the bolus on yearling heifers that had not achieved target weights. They were weighed six weeks later and had caught up with the rest of the group. “They were growing considerably faster than the ones that hadn’t had the bolus so we bolused the whole lot,’’ says Mr Dale.
