Probiotics help calf rearing systems
Success in calf rearing is often measured by minimising health issues and achieving target weaning weights.
One in five commercial beef farmers are now using artificial insemination and more than three quarters of commercial farmers (77%) are buying bulls from breeders that use genetic tools such as estimated breeding values, breeding indexes, artificial insemination, genomics and/or embryo transfer.
The research was done for the Beef + Lamb New Zealand-funded Informing New Zealand Beef programme (INZB).
Gemma Jenkins, programme manager at INZB, says it is encouraging to see the overall increase in awareness of INZB tools, a rise in the understanding of the numbers and science behind beef genetics and the ability to apply the genetic processes on farm, and a continued belief in the use of genetics.
“This is the third year we have undertaken the survey and it’s evident that the industry is making progress. Breeders are confidently using genetic tools,” she says.
Ninety nine per cent of breeders surveyed are using genetic tools and the usage has grown significantly across nearly all types of genetic tools compared to 2021 and 2022.
Ninety per cent of trusted professionals and breeders are also encouraging farmers to use superior genetics. There has also been a significant increase in the number of farmers using artificial insemination, up from 11% to 20% since 2021.
“This is interesting and we’re going to explore more about why we have seen this change,” says Jenkins.
“A significant majority of the farmers responding to the survey also want to be able to compare bulls across breeds.”
The seven-year INZB partnership, supported by B+LNZ, the Ministry for Primary Industries (MPI) and the New Zealand Meat Board, aims to boost the sector’s profits by $460m over the next 25 years.
It is focused on increasing the uptake of use of genetics in the beef industry. The four main components are building a genetic evaluation and data infrastructure, progeny test herds, developing breeding objectives and indexes and developing new data sources.
The industry survey tracks changes in industry attitudes and behaviours towards beef genetics over time. An analysis of the findings and suggestions from respondents will help inform the programme.
There were 336 responses to the survey including 187 commercial farmers, 112 bull breeders and 37 influencers.
