Parrot population in Africa is declining and the need for conservation actions to address threats is increasingly recognized. The situation is worst in Nigeria and if care is not taken, this species of bird will soon go into instinct. The essence of this study was to obtain a database of some body organs of the wild Senegal parrot, a species of bird that is limited in its distribution in this part of the country. Documentation on this species of bird is rare despite they are being hunted for because of its demand as ornamental bird. The mean weights (whole body, gastrointestinal tract (GIT), content and GIT empty) were observed to be 120.50 ± 5.42 g, 18.01 ± 4.80 g and 13.54 ± 5.51 respectively. The liver had mean weight of 4.18 ± 1.82 while the tongue, lower respiratory system (LRS), heart and kidney were observed to be, 2.76 ± 2.14 g, 5.83 ± 1.65, 1.81 ± 0.65 and 0.41 ± 0.05 g. The mean length (whole body + tail) were observed to be 9.85 ± 1.20 cm. The mean lengths (GIT, liver tongue and LRS) were 82.62 ± 2.36 cm, 4.33 ± 1.82 cm, 2.04 ± 0.99 cm and 12.69 ± 2.10 cm respectively with GIT and LRS accounting for 76.93 % and 19.97 % of the body weight. The syrinx is very large suggesting pronounced sound production and the large intestine is void of cecum.
Information on the techniques and morphometric dimensions on performing paravertebral regional anaesthesia in our local breeds of goats is scanty. The proximal and distal paravertebral nerve block postulated by Farquharson and Magda are used in caprine and ovine species by extrapolation. This study was carried out to quantitatively determine the anatomical site of the spinal nerves (T 13 , L 1 . L 2 , L 3 and L 4 ) for the standardized administration of paravertebral regional anaesthesia in West African dwarf goats. Ten adult WAD goats of either sex weighing 10-15kg were used for the study. The animals were euthanized then used for dissection to expose the spinal nerves and subsequently morphometry was carried out. The result of this study showed that the spinal nerve emerges from the intervertebral foramina and bifurcates into dorsal and ventral branches with the dorsal nerve branch passing cranially to the body of the succeeding lumbar transverse process in a caudolateral manner. While the ventral branches of the lumbar nerves each run obliquely, just below the intertransverse ligament, across the space between the transverse processes. The means of (T 13 , L 1, L 2 , L 3 and L 4 ) were considered for the right and left sides of the WAD goats. The mean depth was 3.00±0.38cm while the mean length of nerve was 2.65±0.47cm. This study established reference anatomical landmarks of the spinal nerves 2-3cm away from the spine dorsolateral for proximal approach and 1-1.5cm for the distance of needle placement medially from the tip of the transverse process dorsal and ventral.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
