observation was made of dry matter production (whole plant) and nutrient
composition of Sesbania aculeata 4 months after planting. The
material was fed as a supplement to Damascus does for 23 days before
mating and then through to kidding.
of S. aculeata (leaves + twigs + stalks) was: CP 144, CF 341,
CL 23, NDF 562, ADF 435 and ADL 72 g/kg DM. IVOMD was 50.7%, and energetic
values were: GE 28.27, ME 6.84 and NEL 3.50 MJ/kg DM.
Dry matter and
CP yields of S. aculeata hay were 8269 and 1190 kg/ha, respectively;
and energy yields were: GE 233 765, ME 56 560 and NEL 28 942 MJ/ha.
Half of the
does failed to produce kids. However, the liveweight and duration of
pregnancy (148.8 ± 1.5 d) of the remaining does, and birth weight (4.6
± 1.1 kg) and weaning weight (18.8 ± 5.0 kg) of the kids fell in the
pattern before mating was normal in all does and remained so in does
that had fertile matings; however, the pattern was abnormal (acyclic)
in those which were mated but failed to conceive.
are needed to allay concerns that feeding S. aculeata to breeding
does may cause problems with fertility.
