Energy for maintaining liveweight: an indicator of adaptive abilities of beef cows?uctive performances. In such conditions, individuals’ robustness could be estimated by indicators of animal adaptive abilities which account for energy variations across the productive cycle. In mature suckler cows, the net energy requirements for production are low (30%) compared to those for maint

Response to high altitude grazing in metabolic traits and performance by yak crossbreds and yaks. Yaks are known to be well adapted to cope with low oxygen partial pressure, low temperatures and the harsh mountain environment (Wiener .., 2003), and the resulting energy deficiency. Less information is available on the adaptive capabilities of yak crossbreds. Crossbreeding is a strategy to obtai

Net energy and protein requirements for growth of goats kids ingested in products. Current feeding systems for goats still comprise information extrapolated from sheep and/or cattle. However, the data obtained with these species should not be used for goats, because of differences between these species, such as dietary habits, physical activity, milk and car
