  The effect of Ketamine hydrochloride which is a drug mainly used in birds and cats but was tried on Nigerian dogs. Nine local dogs were administered low (11 mg kg-1) and high (33 mg kg-1) doses of Ketamine hydrochloride parenterally (intramuscularly and subcutaneously). Anaesthetic induction period varied from 2 min for Subcutaneous (SQ) and 1 min for intramuscular routes. Duration of anaesthesia ranged from 32.5 to 265 min for low and high dosages respectively. Clinically, ptyalism was observed in all dogs but was minimal in those that pre-medication (atropine sulphate) was given. It was also observed that forelimbs of animals in group B were spastic. Pharyngeal, pedal, spinal and blink reflexes were lost. Defecation was observed immediately after administration of the drug and there was emesis during recovery. Slight decrease in average rectal temperature of 0.2°C was observed. The dogs tolerated the drug (11 and 33 mg kg-1) to a certain extent and no significant complication was associated with the local dogs; therefore, ketamine hydrochloride could be employed for restraint of uncooperative dogs for minor surgical procedures not requiring muscle relaxation.

  The study involved the evaluation of the effect of T. congolense infection on pyruvate concentration in the serum of Yankassa sheep. Three groups of six sheep each were used; groups A and B were experimentally infected with T. congolense. Animals in group A were treated with Diminazene aceturate after first peak of parasitaemia but group B animals were left untreated. Sera of infected and uninfected control sheep were analyzed using DNS method to determine pyruvate and its concentrations. Group B animals which were not treated had mean values which were lower compared to that of group A (post treatment) and the control. Mean values of 72.4-25.7 g L-1, 79.6-5.2 g L-1 for groups A and B respectively were significantly different (p<0.0001) and indicative that the presence of parasites might have enhanced depletion of the pyruvate in the plasma. However, the cause of pyruvate depletion which occurred when the trypanosome parasites were in general circulation needs further investigations.

  A three year study on the effects of season, ambient temperature and sex on rectal temperature, pulse and respiratory rates (adaptive physiological parameters) of adult one humped camel (Camelus dromedarius) was conducted in Shika-Zaria a sub-humid zone of Nigeria. The average rectal Temperature (T), Pulse (P) and Respiratory (R) rates commonly referred to as ‘TPR’ were 37.0 C, 48.6 beats min 1 and 15.5 breaths min 1 respectively while the ranges were 35.0-40.0 C, 30-57 beats min 1 and 8-23 breaths min 1 respectively. Average TPR values were significantly lower (p< 0.05) in the cold season than in the dry season and no significant difference (p>0.05) between the sexes. The ambient temperature significantly (p< 0.01) influenced the TPR readings with lower values during morning hours than the afternoon hours.

  A total of 518 cattle were examined and sampled at Zaria abattoir from November, 2001 to October, 2002. Skin specimens obtained after slaughter from the neck region were fixed in 10% buffered neutral formalin, processed, sectioned at 5 µm thickness and stained with Haematoxylin and Eosin (H and E) technique. At ante mortem examination 5(2.5%) of the cattle were found with gross lesions of besnoitiosis, 103 (19.8%) were diagnosed with dermatophilosis and 50 (9.7%) with tick infestation. Twenty-nine (29, 5.6%) cattle had both dermatophilosis and tick infestation. Histopathological examination confirmed that the 5 cattle clinically diagnosed with besnoitiosis really had cysts of B. besnoiti in skin sections. Four (4, 2.1%) additional cattle had similar cysts in their skin sections although they had no clinical signs of besnoitiosis. Three (3, 1.5%) of these had gross lesions of dermatophilosis and 1 (0.2%) had ticks on the body. Microscopic examination of crusts from the skin specimens confirmed the presence of filaments of D. congolensis. It was concluded that some cases of besnoitiosis may pass unnoticed at clinical examination where the skins are severely affected with dermatophilosis.

  The concentration change of pyruvate was studied in serum of uninfected and infected sheep with T. congolense. In the uninfected, the mean concentration of 61.23-76.63 mg L-1 of pyruvate was determined using the DNS method. There was a depressed concentration of pyruvate in the two infected groups (A and B); pyruvate level fell to 25.7 mg L-1 in gp A that was treated immediately after the first peak of parasitaemia while in gp B, the concentrations continued to fall (5.2 mg L-1) until the termination of the experiment. The fall might have been as a result of the utilization of the pyruvate by either the host or its conversion to other compounds. It is therefore concluded that animals use the pyruvate or its converted to another compound during trypanosome infection. The decrease in pyruvate levels may be a possible cause of weakness and eventual death in infected animals.

  The prevalence of common diseases of the one humped camel (Camelus dromedarius) introduced into a sub-humid savanna climate of Nigeria for a period of 3 years (2002-2005) is reported. A total of 85 clinical cases were examined. Sixty-seven and thirty-three percents were in the rainy season (June to October) and dry season (November to May) respectively. The most prevalent health problem was helminthosis (31.8%). Egg counts of up to 800 per gram of faeces (epg) were recorded during the rainy season. Traumatic injuries recorded 17.6%, tick infestation 10.6% and footpad perforation 8.2%. Others were conjunctivitis 5.9%, mange 4.7%, abscesses 4.7%, lameness 7.1%, enteritis 2.4%, abortion 2.4%, coccidiosis 2.4%, kneecap dislocation 1.2% and bent-neck syndrome 1.2%. Blood parasites observed were Anaplasma marginale and microfilaria. Two male camels died during the period of study, the first death being due to pneumogastroenteritis and the second of bent-neck syndrome. The disease conditions showed remarkable seasonal pattern of occurrence with higher prevalence during the rainy season. The undiagnosed cases of musculoskeletal incoordination needs further research for effective introduction of camels into sub humid zone of Nigeria.

  The study was carried out to evaluate the draught performance of the dromedary and Bunaji work bulls as draught animals for ridging, ploughing and weeding operations in a sub-humid environment of Nigeria. Four work dromedaries singly harnessed and 8 Bunaji work bulls yoked in pairs were used for the evaluation. The camels’ mean weight was 450±12.8 kg while a pair of bulls weighed 760±15.4 kg. The animals were made to plough, ridge and weed an area of 1500 m2 of uncultivated flat land. The absolute draught force produced by one dromedary for ridging (0.80 kN), weeding (0.36 kN) and ploughing (0.18 kN) were not significantly different (p>0.05) from that produced by a pair of work bulls (0.79 kN, 0.30 kN, 0.30 kN) for same operations although the live weight of a pair of work bulls (760±15.4 kg) was significantly (p< 0.01) higher than that of a single dromedary (450±12.8 kg). The bulls ridged 0.23 ha of land per hour (1 ha / 4.4 h) which was significantly (p< 0.01) faster than the camels’ 0.18 ha per hour (1 ha 5.3 h 1). It is thus conclusive from this study that, the one humped camel can be efficiently utilized as an alternative draught ruminant in the sub-humid savanna zone of Nigeria.

  The prevalence of ovine haemo and gastrointestinal parasite in the 8 Local Government Areas (LGAs) of Northern Nigeria over a period of 10 months (February -October 2002) was evaluated. Blood and faecal samples were obtained from flocks of sheep herded with cattle. The study involved the random examination of 101 sheep of both sexes irrespective of breed, age between 9 and 36 months. Ninety percent of sheep examined were infected with gastrointestinal parasite while 33% were infected with haemoparasite. Mixed infections of haemo-and gastrointestinal parasite occured in 34.6% of sheep examined. Seventy seven percent of these occurred as single haemoparasitic infections concurrently with one or two helminth species, 14.3% occurred as double haemoparasitic infections concurrently with one or two helminth species while only 8.6% occured as triple haemoparasite infection concurrently with one specie of helminth. Gastrointestinal and heamoparasitic infections appear to be widespread in the area of study. Much of the infection seem to be subclinical and could indirectly cause production losses without attracting farmers attention to institute control measures.

  A survey of the prevalence of gastrointestinal parasites in nomadic sheep was conducted during the period of February to October 2002. Data were gathered from 28 flocks of sheep with a total of 101Yankassa sheep in 8 Local Government Areas (LGAs) of Northern Nigeria. High prevalence rate was observed in all the LGAs, Igabi (94.0%), Kagarko (100.0%), Birnin Gwari (100.0%), Doka Keffi (100.0%), Lapai (83.0%) Tafa (100.0%) and Doguwa (80.0%) except Kankiya which had 50%. The mean helminth prevalence rates according to their species were Haemonchus contortus 49.9%, Cooperia curtecie 39.6%, Oesophagostomum sp. 14.9% and Trichostrongylus sp. 1.9%. Doka, LGA in Nasarawa State had the highest (66.7%) prevalence rate for H. contortus with the lowest (20%) obtained from Kankiya LGA. Cooperia curtecie had the highest (100%) mean prevalence rate in Kangarko LGA of Kaduna State while Birnin Gwari LGA of the same State recorded the lowest mean prevalence (13.4%). The mean prevalence for Oesophagostomum sp. was low, 30.0% was the highest value observed in Kankiya LGA of Katsina state, the lowest value(10.0%) was observed in Doguwa LGA of Kano state. Trichostrongylus sp. has the lowest mean prevalence (6.6%) and was observed only in Birnin Gwari LGA of Kaduna state. Mixed infection constituted substantial (70.3%) proportion of all gastrointestinal nematode infection in all the sampled areas. The frequency of occurrence of single infection is 17.4%, double infections 39.5% triple infections 37.9% and quadruple infections 5.8%. Most of the animals examined had low to moderate infection, suggesting that the infections were probably at sub-clinical level.
