Heat af­fects per­for­mance

The Cobram Courier - - NEWS -

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.
