Rabbits
Green vines
Green vines are very palatable for young rabbits (Harris et al., 1983). They are commonly used without any problem by local rabbit breeders in Nigeria or in Java for example (Carew et al., 1989; Prawirodigdo, 1985).
Bean straw
Common bean straw could be used safely as fibre source in rabbit feeding up to 30-40% of complete diets (Gippert et al., 1988; Ferreira et al., 1997; Gomes et al., 1999). Due to the variability of the composition of this product, the energy value has been shown to vary from less than 4 MJ/kg (Ferreira et al., 1997) to 9.6 MJ/kg (Gippert et al., 1988).
Beans
Common beans, either raw or toasted, are not palatable for rabbits. When offered to rabbits in free choice together with 3 other legume seeds (also raw or toasted), beans intake was less than 0.8% of the total daily intake, a much lower value than the intake obtained with peas (33%), soybeans (28%) and faba beans (27%) (Johnston et al., 1989). A high decrease of live weight gain (10 vs 38.6 g/d) was observed when soybean meal was totally replaced by raw pinto beans in a balanced diet. Furthermore, diarrhoea was very prevalent in rabbits fed the raw beans. Autoclaving improved growth rate up to 20 g/d and reduced diarrhoea incidence, but feed intake remained low (72.8 vs 122.9 g/d for the control diet) and similar to that obtained with raw beans (Sanchez et al., 1983). For these reasons, raw or heat treated beans could not be recommended for rabbit feeding.
