Heat affects performance
United States animal science expert Geoff Dhal is visiting Australia to discuss the impact of heat stress on dry cow performance, calf health and growth.
An animal science professor at Florida University, Dr Dahl researches animal production to optimise health and performance.
Dr Dahl’s research has found heat stress during late gestation has a significant effect on cow health before and after birth and on their calves’ development.
In addition to impaired immune function during the transition period, heat stress during the dry period adversely affects mammary gland development.
Dr Dahl will discuss the importance of keeping cows cool in dry times.
At two on-farm workshops, he will offer practical advice for managing the herd to reduce heat stress.
The focus of the workshops is on low-cost solutions, not on expensive infrastructure.
‘‘With a dry summer forecast for 2018-19, it’s important that dairy farmers are prepared to manage heat stress in their herd,’’ Murray Dairy regional extension officer Lisa Birrell said.
‘‘By maintaining good herd health and performance, farmers will get better production outcomes, which will help with the tight season.’’
Murray Dairy invites all farmers to workshops in Deniliquin on October 22 and Bamawm on October 23. For details, visit the Murray Dairy website.
