MANAGEMENT OF M.BOVIS AT CRV:
CRV Ambreed has a strong strategic focus on biosecurity, built up over many years, and as the second largest producer of AI semen in New Zealand we are confident our biosecurity protocols and procedures will effectively mitigate the known risks associated with the current M.Bovis outbreak.
In order to ensure our bulls and staff visiting farms maintain appropriate biosecurity standards, we have highlighted below key components that relate to the management of M.Bovis at CRV Ambreed.
International disease testing standards are followed:…read more ›
Four new ‘environmentally friendly’ bulls have been included as part of CRV Ambreed’s latest team of proven sires.
New graduates Ambzed Powells CORTEX S2F, Tralee Shadow DART-ET S2F, Glen Leith Degree OMNIBUS, and Calrenah And WATCHMAN ET are four of 28 bulls in the CRV Ambreed LowN Sires team for 2018.
“In March last year, we announced our plans to market bulls that are genetically superior for a new trait that is related to the amount of urea nitrogen in milk,” says Product Manager Oceania Peter van Elzakker.
He says the LowN Sires bull team was popular when…read more ›
Eighteen new graduate bulls have been awarded gold medal status as part of CRV Ambreed’s latest team of proven sires.
The bulls and their breeders have been through a rigorous, four-year selection process, which identifies those sires with the highest genetic merit.
CRV Ambreed’s proven sires feature in the herd improvement company’s annual catalogue, which thousands of dairy farmers peruse each year to select the right genetics to meet their herd improvement goals.
Product Manager Oceania Peter van Elzakker says dairy farmers want milking herds that are healt…read more ›
New Zealand’s 4.8 million milking cows excrete 1000 tonnes of nitrogen a day in their urine and 200 tonnes of that ultimately ends up leaching into groundwater.
CRV Ambreed has determined the daily numbers using existing information related to milk urea concentration in daily bulk milk reports. The nitrogen numbers are large and the herd improvement company says it’s important to see them reduced.
CRV Ambreed’s head of R&D Phil Beatson says CRV Ambreed is encouraging conversations about how New Zealand dairy farmers could make use of the Milk Urea concentrati…read more ›
Every day farmers supplying Open Country Dairies, Fonterra, Synlait, Westland Milk Products and possibly other processors receive the Milk Urea concentration (MU) of their bulk milk sample which is also analysed for protein, fat and somatic cell content as the basis of their milk cheque. Across NZ the average MU value is 30 units.
MU gives us a good idea of how much Nitrogen is excreted in urine – this is called urinary nitrogen. Overseas plus limited NZ research shows a straight-line relationship between MU and grams of urinary nitrogen excreted per day per cow. On…read more ›
