      Abstract: The increase in awareness and practice of reptile domestication has led to more knowledge of reptiles medicine in Nigeria. However, with this awareness, there is a paucity of information on the clinical presentation of crocodiles in health and disease. A study was therefore carried out using ten 21⁄2 to 3 years old captive juvenile crocodiles Crocodylus niloticus with live body weights of 1.5-3 kg having haemo-infection. Three millilitres of blood was collected through the caudal tail vein for haematological analysis. A blood smear was used for morphological identification of haemoparasites. The haematological values obtained were; PCV (%) 25.70 ± 4.3, Hb (g/dl) 7.80±6.6, RBC (×106/μl) 1.24±0.37, MCV (fl) 197.50±25.72, MCHC (g/dl) 33.6±1.33, Platelet (μl) 112,800±46,168.29, WBC (103/μl) 6595±1,594.80, lymphocytes (μl) 3,544±1238.60, heterophils (μl) 2,670±999.3, monocytes (μl) 2.0±1.0, eosinophils (μl) 136 ± 8.0 and the basophils (μl) 111 ± 87. There was no significant difference (P>0.05) in all the haematological parameters except for eosinophils and basophils which were significantly increased in the naturally infected crocodiles. Haemoproteus, Plasmodium and Hepatozoon species were morphologically identified in this study. There was no significant clinical alteration in haematological profiles obtained with haemoparasiteamia in this study. The findings from this study could serve as baseline values for clinical diagnostic investigation in our environment.

      Abstract: Despite pigs abundance among livestock population, Gastrointestinal parasites (GIP) have been a major constraint to porcine production in Nigeria among various diseases. However, difficulties abound in estimating parasitic burden in pigs, due to variation in daily faecal output of GIP, this is worsened by dearth of reliable and sensitive diagnostic techniques.With simple random sampling technique for three consecutive days, readily available and affordable faecal diagnostic techniques were compared using 71 pigs sampled per rectum from six different farms. Four parasitological techniques (direct smear, centrifugal flotation, formol-ethyl-acetate sedimentation, and Stoll egg counting) were employed for the diagnosis of GIP on 213 faecal samples collected. Seventy of the pigs sampled (98.6%) were positive for one or more parasites while one pig (1.4%) was negative with all diagnostic techniques used. Cysts, eggs and oocysts of ten different gastrointestinal parasites were identified: nematodes (40%), trematodes (20%), cestodes (10%) and protozoa (30%). For the three days, mean cyst per gram was 427.92±57.15 while the mean Oocyst per gram was 155.79±29.49 and mean egg per gram was 137.5± 23.52 with no statistical significance in daily output.Technique sensitivities were: Centrifugal flotation (71.98%), Stoll egg counting (71.43%), Formol-ethyl-acetate (67.40%) and direct smear (66.48%). All the concentration techniques were more sensitive for diagnosis of GIP in pigs, the strength of combining techniques for faecal analysis were discussed. The observation of some zoonotic GIP in the study area calls for proper public health awareness.

  • Gonadosomatic index, epididymal mass index and haematology of male Wistar
           rat treated with carrot juice

      Abstract: This study investigated the haematology, Gonadosomatic Index (GSI) and Epididymal Mass Index (EMI) of male Wistar rats treated with carrot juice. Carrot has been evaluated for a wide spectrum of activities including; wound healing, gastroprotective effect, Hepatoprotective effects against carbon tetrachloride intoxication in mouse liver cells. Morphometric analysis on the testis of any species or breed is necessary for assessing and estimating quantitative changes in testicular component and spermatogenic functions arising from factors such as age, season, temperature and diseases. Nutrition has some influence on testicular parameters and gonadal sperm reserves. Thirty-five (35) albino rats (Wistar strain) were used for this study. They were grouped into three: group A (treated with 4.08g of carrot juice), group B (treated with 8.16g) and group C (control) and were treated for 7 days. Blood and semen samples were collected on day 1, day 8, and day 15. The result revealed a significant increase in GSI and EMI for group B when compared to group A and group C this increase was due to an increase in the dose of the juice given to group B animals. There was also an increase in lymphocytes for the treatment group on day 1 post-treatment. In conclusion, carrot juice works more effectively after treatment with 8.16g/ kg body weight to improve male reproductive potentials thus found to be more effective to improve spermatogenesis or Gonadosomatic Index and Epididymal Mass Index

  • Tetanus (lock jaw) in a West African Dwarf Ram used for ram fighting
           competition in Ibadan, Nigeria: A case report

      Abstract: Ram fighting is one of the unimaginable sports practiced all around the World. It is often associated with all sorts of injuries which may predispose animals to tetanus. Tetanus is an acute, severe and potentially fatal toxin-mediated disease caused by Clostridium tetani infection. This organism thrives under anaerobic conditions, such as unclean environment, contaminated wounds. A case of an adult West African Dwarf Ram, weighing 45kg presented with generalized stiffness, mild opistotonus, difficulty in swallowing and signs of generalized pain was presented. On physical examination, rapid breathing and mild bloat were observed, but every other clinical parameter was within the normal reference values. Tentative diagnosis of tetanus associated with injuries sustained during animal figthing. The patient was treated with human tetanus immunoglobulin followed by intravenous metronidazole, procaine penicillin streptomycin and diazepam injection administered intramuscularly. High dose of multivitamins was administered I/M. The symptoms were relieved after three hours of intensive treatment each day for two consecutive days. The client failed to present the patient to the clinic for follow-up on the third day citing cost and distance to the clinic as excuses. To the authors’ knowledge a tetanus infection associated with injury from Ram fight has not been previously reported in Ibadan, Nigeria.

      Abstract: A two and half year old post parturient West African Dwarf ewe, weighing 22 kgs and with black anterior and white posterior body coat was presented at the Veterinary Teaching Hospital, University of Ibadan, with complaints of abdominal distension, sudden laboured breathing and anorexia. The animal was said to have lambed 7 days earlier and was fed with cassava peels and grasses. On clinical examination, the eye ball appeared bulged and starry; the stomach was hard on palpation with frothy buccal exudate and persistent grinding of teeth. The heart rate was 68/minute, respiratory rate was 15/minute and rectal temperature was 39.8℃. Bloat was clinically diagnosed. With the patient properly restrained, an improvised stomach tube was rinsed in vegetable oil and slowly inserted through the oesophagus into the rumen and the gas eructated. Liquid paraffin (15 mls) was subsequently introduced into the rumen via the tube. On removing the stomach tube, a long strand of fresh undigested pasture came out with the tube from the gastrointestinal tract. The hard stomach was thereafter relieved within 5 minutes of the procedure. Long acting Oxytetracycline hydrochloride (2 mls) and 1ml Diclofenac were administered (intramuscularly) simultaneously at different injection sites. Plenty of water was advised to be given orally after 30minutes. Complication resolved and complete recovery of the ewe was achieved after 5 consecutive days of treatment.
