Cows that can take hot cli­mates

South Waikato News - - Agribusiness - GER­ALD PIDDOCK

Bull se­men that pro­duces dairy cows ca­pa­ble of per­form­ing in trop­i­cal coun­tries has been re­leased by Waikato com­pany Dairy So­lu­tionz.

The three bulls from the new Ki­wipole breed - Slick Pathos, Slick Eros and his brother Slick Himeros - are be­lieved to be the world’s first ho­mozy­gous ‘‘slick’’ dairy type bulls avail­able for ex­port se­men sales.

The bulls will trans­mit the heat tol­er­ance as­so­ci­ated with the ‘‘slick gene’’ to all of their daugh­ters. This gene al­lows cat­tle to per­form in hot and hu­mid con­di­tions, with main­tained and even im­proved milk pro­duc­tion.

Slick genes will bet­ter reg­u­late body tem­per­a­ture while main­tain­ing milk yield un­der heat stress.

Dairy So­lu­tionz re­cently launched the breed at the Tu­lare World Ag Expo event in Cal­i­for­nia, in part­ner­ship with St­ge­net­ics.

Dairy So­lu­tionz chief ex­ec­u­tive Derek Fair­weather said the launch was a chance to show­case the ge­net­ics to farm­ers who run North Amer­ica’s large scale mega-dairies.

‘‘It’s not a so­lu­tion for the whole of Amer­ica, there’s niche cli­mates and con­di­tions where it’s got a role but it’s a pretty com­pelling value propo­si­tion and the sci­ence is in be­hind it.’’

Heat stress was a sig­nif­i­cant is­sue in the United States among cat­tle, he said.

‘‘You’re ei­ther in­cur­ring a lot of costs to mod­er­ate the en­vi­ron­ment and it gets over 100 de­grees fahren­heit (37degc) pretty fre­quently and that’s pretty hot.’’

He also met with farm­ers from Nige­ria, Ethiopia and Mex­ico who were in­ter­ested in the ge­net­ics. ian and Pak­istan mar­kets. Philip­pines sup­plier Dave Hay­man has ex­ported New Zealand dairy cows to the Philip­pines and has used the Ki­wipole bull se­men, with calv­ing tak­ing place soon.

‘‘In the Philip­pines, it’s a tough cli­mate for dairy pro­duc­tion, and these ge­net­ics will make the prog­eny of the New Zealand live heifers that we im­ported, more ro­bust and pro­duc­tive.’’


Dairy So­lu­tionz will be look­ing to mar­ket their heat tol­er­ant dairy ge­net­ics in trop­i­cal coun­tries as well as New Zealand.
