By-products and feedingConclusions
Improving by-products at source of considerablestrategic importance for livestock feeding
Integrated breeding, supplementation, processing, transport strategies required
Respectable level of livestock productivity achievable in by-product based feeding systems

Interaction of livestock numbers, productivity level, feed requirements
and CH4 emissions
Conclusions
Strategies for increasing per animal milk productivity highest effects on resource use, feed requirements and
greenhouse emissions
At available feed qualities of 7.4 to 8.5 MJ ME/kg and intakes of 3.2 to 3.6% of LW daily milk yields of
about 9 to 12 l are achievable.
Higher levels questionable because of lack of concentrates
