When a cow produces 1,000 lbs. of butterfat in a year, that is good news for her owner, big news for dairymen. Last week the American Jersey Cattle Club was celebrating the biggest news yet: a new world's butterfat champion. Six-year-old, 1,000-lb. Sybil Tessie Lorna 996685, a Jersey owned by L. A. Hulbert of Independence, Ore., had produced 17,121 lbs. of milk in the official 305-day test period, enough butterfat to outweigh herself by 20 lbs. Previous holder of the all-breed record was Aaltje Salo Hengerveld Segis 823991, a Vermont...
...cows be brought to them. Nevertheless for many months Argentine cattlemen have had their eyes on two fine Holstein-Friesian bulls at the U. S. Department of Agriculture station in Beltsville, Md.: Chief Piebe Ormsby Burke and Double Gerber Colantha Hero, both renowned for transmitting high milk and butterfat productivity to their female offspring. Last July an attache of the Argentine Embassy in Washington approached Roy Ralph Graves of the Beltsville station, proposed that sperm from the two bulls be bottled and shipped to Argentina...
There are two ways of measuring a cow's production: by actual amount of milk given or by the milk's butterfat content. World records for total milk production and total butterfat production have always been held by different cows. Last week a purebred Holstein on Carnation Co.'s experimental dairy farm near Seattle finished a year's test which set new world records in both classifications. The cow: Carnation Ormsby Butter King, known to her attendant as Daisy. In 365 days Daisy produced 38,606.6 Ib. of milk and 1,420 Ib. of butterfat. That...

...could find what they wanted. They found first, as others had found, that a cow inherits productive capacity from both dam and sire. They found further that, as regards quantity of milk, a cow gets seven-tenths of her inheritance from whichever parent has the higher inheritance; as regards butterfat percentage, four-tenths of her inheritance from whichever parent is higher. The dam's inheritance was obvious from her output. The problem remained how to evaluate the bull's transmitting capacity. The Prentice group chose the method of systematically comparing the yield of bulls' daughters with...
