Four Pelibuey sheep fitted with flexible rumen cannula were fed increasing levels of Gliricidia sepium foliage (gliricidia) in a 4 × 4 Latin square design. Treatments were: control, 10, 20 and 30% (dry basis) of gliricidia mixed in a basal diet of Cynodon nlemfuensis (stargrass) hay. Dry matter (DM), organic matter (OM) and crude protein (CP) intakes were linearly increased (P < 0.05) from 45.2, 40.4, 2.0 to 71.5, 63.3 and 6.8 g/kg W^0.75/d, for the control and the 30% gliricidia diet, respectively. Similarly, increments of gliricidia in the diet resulted in a linear increase in DM, OM and CP apparent disgestibilities from 43.7, 48.4 and 27.0 to 50.7, 54.7 and 57.3%, for the control and 30% gliricidia diet, respectively. There was no effect (P > 0.05) of supplementation with gliricidia on rumen dry matter digestion of stargrass. Microbial nitrogen (N) supply to the small intestine had a trend towards an increase from 4.9, for the control, to 9.6 g N/d, for the 30% diet, though it was not significant (P > 0.05). It is concluded that, gliricidia might be incorporated into low quality diets since it increases total DM intake, supplies highly degradable N to the rumen and appears to increase the microbial N supply to the small intestine of sheep.

The purpose of this investigation was to define the magnetic resonance (MR) imaging appearance of the brain and associated structures of the equine head. MR images were acquired in oblique dorsal (T2-weighted), sagittal (T1-weighted), and transverse planes (T2-weighted), using a magnet of 1.5 Tesla and a human body coil. Relevant anatomic structures were identified and labeled at each level. The resulting images provided excellent anatomic detail of the cranioencephalic structures. Annotated MR images from this study are intended as a reference for clinical imaging studies of the equine head, specially in the diagnosis of brain diseases in the horse.  相似文献
