The Rural Voice, 2000-08, Page 13Scrap Book Research shows value of cows with big appetites Selecting cows that have the ability to eat more during early lactation may reduce stress-related health problems and make for healthier animals, say University of Guelph researchers. Research associate Dr. Paul Boettcher from the Centre for Gen- etic Improvement of Livestock (CGIL) and graduate student Beth- any Collard are trying to uncover a relationship between a dairy cow's energy balance (the difference between energy consumed and energy used for milk production, growth and maintenance) in early lactation, and health and reproductive problems during the course of that lactation. "We hope to find a role for genetic factors in the relationship between energy intake and milk yields," says Collard. "If we could breed for a cow that eats more in early lactation, then maybe that cow could better withstand stresses and be healthier." Even when plenty of food is offered, many early lactating cows fail to eat enough feed to meet their energy needs. If the energy a cow requires for milk production and tissue maintenance exceeds what she's consuming in her feed, she'll experience a negative energy balance that could lead to health problems. However, increasing the feed energy concentration puts the cow at risk for digestive problems. From information the team gathered at Agriculture and Agri - Food Canada's dairy research station in Lennoxville, Quebec, they learned that cows with a longer negative energy balance experienced greater health problems. They had higher incidences of locomotive problems like laminitis — inflammation of the soft tissues of the foot — and digestive problems.0 — Source: Centre for Genetic Improvement of Livestock Update 2000 Tractor & Combine Parts We're your New, Used i Reman Parts Specialists Call us for all your Engine Overhaul n..ds ph. 1-800-372-7149 fax 1-800-372-7150 FAWC ETT Tractor Supply Ltd. www.fawcett.cc sales (a fawcett.cc 2126 Road 120.
