The effects of 3 different stocking rates (1, 2 and 3 cows/ha/yr) on sward structure and the amount and pattern of live leaf defoliation were studied at different hierarchical levels within swards of signal grass (Brachiaria decumbens ) pastures. Permanently marked plants and tillers were followe...
A study was carried out to test: (1) if the prediction of in vitro gas production of kikuyu grass (Pennisetum clandestinum) samples by near-infrared reflectance spectroscopy (NIRS) could be improved by the use of a spectrally-structured sample population; and (2) if the parameters from exponentia...
Today's global population of 7 billion is predicted to expand to more than 9 billion by 2050. Will that more crowded world be able to produce enough food for everyone? And should livestock be part of evolving food security plans? In this 26 minute seminar, Mario Herrero, agro-ecological systems a...

In these systems the major inputs and outputs are managed by human agency – the farmers. To analyse potential developmental pathways of smallholder farming systems in sub-Saharan Afri...
Nine mathematical models were compared for their ability to predict daily milk yields (n = 294,986) in standard 305-d and extended lactations of dairy cows of Costa Rica. Lactations were classified by parity (first and later), lactation length (9 to 10, 11 to 12, 13 to 14, 15 to 16, and 16 to 17 ...
