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.
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.
Slick Cows Handle the Heat Better
Better Regulation of Body Temperature Under Heat Stress
- Increased sweating rate
- Lower respiration rate
- Lower vaginal temperature
Superior Performance Under Heat Stress
- Better dry matter intake
- Higher milk yield
Shorter Calving Intervals
- Better reproductive efficiency
- Soundness of feet and legs
Replacement Heifers Reach Puberty Faster
- Better weight gain in hot months
