Your weekly glimpse into research in action at Southern Dairy Hub.
Insights
Pasture covers continue to be high this week and therefore will continue to use late calving cows to help manage post grazing residuals behind the milkers as the ground conditions allow.
We will continue to feed 0.5kg Inshed feed to ensure cows get the required magnesium and calcium at this time of the year. We are dusting additional magnesium oxide and lime flour on paddocks for the colostrum mob and magnesium oxide for springers and milkers on effluent paddocks. This is to help prevent/manage metabolic issues.
We are on target to finish our swede paddocks at the end of the month with our later calving cows. We are very happy with the area allocation and crop yield for this season.
Last week we mentioned in our notes we were recording the brix testing colostrum grade against each cow. It’s surprising the variability of colostrum colour to brix results – when you think it should be gold quality visually it is not always 😊.
Soil temperatures have continued to fluctuate over the last couple of weeks and therefore have not applied N fertiliser to date. We are looking for ideal ground conditions and a rising ground temperatures above 7 degrees.
We used the mastatest tool this week to determine best treatment for a mastitis. We are loving the detail around the best suited treatment to the type of infection. We certainly believe this tool will ensure a proactive timely treatment plan, saving costs to help for a speedier recovery of the cow. A high percentage of cows will not require treatment and therefore a reduction in antibiotic use. Check out the AgriHealth website for more information AgriHealth.
