A further reduction in the crude protein content of pig feed is challenging, but possible. This study shows that nitrogen utilisation efficiency can be improved and emissions reduced without compromising performance or meat quality.
After calving, dairy cows often have an energy deficit and mobilise body fat, with consequences for health, animal welfare and performance. Agroscope researchers have now shown that cows’ energy status can also be measured from exhaled air.
Goats may be appealing, but very few goat farmers can make money from them. Dairy goats become economically viable only when annual milk production reaches at least 100 tonnes, which equates to around 120 to 180 dairy goats, depending on yield.
