Jenny-Lou Marshall Ousts His Full Brother… Then Dies

Cattle breeding company Dairy Daughters has reported a bitter-sweet success story for one of its top type and milk production bulls, Jenny-Lou Marshall.

The bull (otherwise known as Lou) came through the last Holstein proof run with such outstanding performance figures - including over three points on type and more than 700kg milk - that the company was keen to secure extra semen supplies to offer British farmers.

But having clinched one of the best deals they could and secured most of the international semen stocks of the bull, he promptly died, inevitably curtailing future supplies!

“We were devastated to hear the news but relieved that we had at least secured what supplies there were of such a popular bull,” says Alison Lovell from Dairy Daughters. “For years, he has been almost level-pegging with his perhaps more well-known full brother, Jenny-Lou Mrshl Toystory, but now he has moved some way ahead on many important traits. This includes Type Merit at 3.02; mammary composite at 2.92, ranking him 16th in the UK; legs and feet at 2.04 and weight of milk at 712kg.

“The reports we have had back from British farmers have always given us enormous confidence in this bull and these figures corroborate their findings.

“His better performance results from 113 second crop daughters in 79 herds being added to his proof, giving him a total of 461 daughters in 305 herds,” she says.

Lou is a son of the popular Mara-Thon BW Marshall and out of the Norrielake Cleitus Luke daughter, Jenny-Lou Patron Toyane.

His daughters are tall and powerful with dairy strength, extremely wide rumps, ideal pin setting and good feet and legs. Udders are very well attached and have a strong ligament, while front teats are closely spaced and teat length is longer than average.

“With the bonus of being BB for kappa casein – an important benefit in milk destined for cheese – we don’t expect supplies of this bull will be around for too long,” concludes Miss Lovell.
