Siemers Lr Broker – Developed for Hot Climates

The impact of heat stress to livestock is increasing rapidly. Environments with high temperatures and humidity are detrimental to the productivity and sustainability of commercial animal agriculture. Improved heat tolerance through a cooler hair coat is a novel trait in dairy breeding.

HEAT STRESS AND ECONOMIC LOSSES

How much is heat stress costing you? Heat stress losses in the dairy industry add up to billions of dollars every year, due to decreases in dry matter intake, milk yield, and impaired reproductive efficiency.

Broker’s Genetic Information

The Genetic Advantage

Holsteins with slick hair have superior thermoregulatory ability compared with non-slick animals and experience a less drastic loss in performance (dry matter intake, milk yield, reproductive efficiency) during hot months.

MOST EFFICIENT APPROACH FOR HEAT STRESS

Every year millions of dollars are invested in heat stress reduction equipment and strategies. Selecting cattle for increased thermotolerance is a sustainable strategy to reduce the severity of heat stress effects.
