Bezerra, A. R. G. F. ; Malafaia, P. ; Mancini, M. C. ; Bezerra, E. S. ; Vieira, R. A. M., 2005. Kinetic parameters of the ruminal in vitro degradation of feedstuffs given to different ruminant species. Arq. Bras. Med. Vet. Zootec., 57 (4): 494-501

The estimation of the ruminal kinetic parameters of pumpkin, sweet potatoes, beet, broccoli, carrot, lucerne hay, lucerne pellet and bean, currently used for feeding wild and domestic ruminants raised in the Rio de Janeiro Zoo, was made through in vitro incubation of the feedstuffs together with ruminal fluid obtained from aoudad (Ammotragus lervia), sambar deer (Cervus unicolor), eland (Taurotragus oryx), cattle (Bos taurus), buffalo (Bubalus bubalis), goat (Capra hircus) and sheep (Ovis aries). The gas production technique was used to obtain gas profiles, and the data were fitted by the mono or double compartmental model. The kinetic parameters were discrepant among both, animals and feedstuffs, and the double compartmental model gave the best estimation. Ruminal inocula from domestic ruminants can not be used to estimate the kinetic parameters of ruminal degradation of feedstuffs for wild ruminants.
