Stall Sizes for Jerseys

(2016 Jersey Canada) It is reasonable to expect that the stall size for Jersey's will be smaller than what is required for larger cows. Read more about our recommendations for the ideal stall size to keep your Jerseys comfortable, safe and productive. Read more ...

(2015 Dairy Farmers of Canada - ProAction) Jerseys require 80% of the space that a mature Holstein cow requires. Read more in the ProAction Animal Care Reference Manual on page 7.

Economic Analysis of Dairy Breeds

(2014 University of Guelph) E. Currie, J. James, J. Whytock, L. Carty, S. Wick, Economic Analysis of Dairy Breeds: Which Breed is the Best, 2014, University of Guelph

The Jersey breed is the most economical and financially viable dairy breed. The smaller size is a benefit due to efficient conversion of feed, lower labour costs, higher components, lower health and reproduction costs and lower investment in fixed assets.

Environmental Impact of of Jersey to Holstein Milk for Cheese

(2012 Journal of Dairy Science) An article in the Journal of Dairy Science compared the environmental impact of Jersey to Holstein milk for cheese production. It concluded that producing cheddar cheese from Jersey milk consumes fewer natural resources and has a lower environmental impact compared with using milk from Holstein cows. For Jerseys and Holsteins to produce the same amount of protein, milkfat and other solids, the Jersey population requires 32% LESS water, uses 11% LESS land and substantially LESS fossil fuels, and produces LESS waste. The research claimed a 20% reduction in the total carbon footprint. Read more ...

(Agricultural Operations Regulation, Environment Quality Act: chapter Q-2, r. 26) A milking Jersey cow produces 55% less phosphorus (P2O5) in her manure than other dairy breeds. Phosphorus output is just one of many ways that Canadian Jerseys use their body size and high-component milk production to demonstrate their efficiency, profitability, and opportunity! This fact is recognized by the Government of Quebec, as outlined in the Agricultural Operations Regulation Environment Quality Act, and represents an incredible opportunity for dairy producers everywhere to efficiently administering their nutrient management program while maximizing their herd size.

Improving The Odds With Sex-Sorted Semen

(2009 OMAFRA) Average first-service conception rates using sex-sorted semen for Jersey heifers is reported at 53% while the average is 47% for industry heifers.

In the right circumstances, using sex-sorted semen in virgin heifers can offer a financial opportunity. Once considered a dairy farmer's pipedream, sexed semen for artificial insemination has become commercially available from all North American studs on a select basis at a premium price. Although this semen greatly improves your odds of producing a heifer calf, it is fair to ask whether the extra cost is worth it. Read more ... (Source:
