This study was undertaken to determine the anti rabies virus antibody (ARVA) levels achieved by parenteral anti rabies vaccination in dogs. Quantitative detection of ARVA in the serum samples of vaccinated (n=102) and unvaccinated (n=14) dogs belonging to six age groups, viz., <3 months, 3-6 months, 6-12 months, 1-2 years, 2-3 years and >3 years was carried out by employing an indirect immunoenzymatic technique. Although, all the vaccinated dogs showed satisfactory levels (= 0.6 IU/ml) of ARVA (mean: 3.1 IU/ml, range: 0.6-13.6 IU/ml), the unvaccinated dogs did not possess adequate antibody levels (mean: 0.41 IU/ml, range: 0.13-0.59 IU/ml) to protect them from the disease. There was no significant (p>0.05) difference in the antibody responses between the male and female dogs. Antibodies which appear to be of maternal origin found in the unvaccinated puppies under 3 months of age were also inadequate (mean: 0.47 IU/ml, range: 0.3-0.59 IU/ml). On the contrary, puppies which had been vaccinated before 3 months possessed adequate levels (mean: 0.79 IU/ml, range: 0.66-1.2 IU/ml) of ARVA. However, their ARVA levels were significantly (p>0.05) lower than those of the dogs vaccinated after 3 months of age. The ARVA levels of the unvaccinated dogs of 3-6 months (mean: 0.16 IU/ml, range: 0.13- 0.18 IU/ml) were significantly (p<0.05) lower than those of the unvaccinated puppies under 3 months. The adult dogs over 3 years and vaccinated = 3 times against rabies showed the highest levels (mean: 8.2 IU/ml, range: 3.5-13.6 IU/ml) of ARVA. The present findings indicate that although there is a high individual variation in the levels of humoral response, the pre-exposure parenteral vaccination is an effective prophylaxis against rabies in dogs. Furthermore, puppies below 3 months should also be included in vaccination schedules and they be given a booster vaccination at 3 months of age to achieve a long lasting protection from the disease.

An experiment was conducted to evaluate the effects of supplementation of nitrogen through UMMB on the performance of dairy cows fed with good quality forage based diets. Twelve multiparous dairy cows were fed Co3 (Pennisetum purpureum x Pennisetum americanum; Hybrid Napier) ad-libitum and dairy cow concentrate feed 2 kg/d. The diet was either unsupplemented or provided with 300g/d of crushed UMMB at 3 equal meals during the day in a 2 period cross-over design with each period consisting of 6 weeks. Supplementation of UMMB had no effect on DMI and contents of milk fat, protein, SNF, Ca and P. Similarly, plasma Ca and P levels were not affected by the treatment. However, UMMB supplementation increased (P<0.05) milk yield and yields of milk fat, protein and SNF by 12, 17, 13 and 13% respectively compared with control diet fed animals. In addition, UMMB supplemented animals had a higher (P<0.05) BW than those fed the control diets. Current findings suggested that improvement of production and performance with UMMB supplementation is mainly due to improved digestibility of the basal diet.

In analgesic pre-treatment during thiobarbiturate intra venous general anaesthesia in atropinized normal dogs the duration of anaesthesia was more prolonged with pentazocine but the recovery was smoother with lysine acetyl salicylate (LAS). Neuromuscular incoordination was virtually absent with LAS pre-medication. Cardio-pulmonary suppression was subdued with pentazocine and minimal with LAS pre-medication. Only moderate decreases in rectal temperature suggested that the thermo-regulatory mechanisms and metabolic rate were not affected significantly in either treatment. Absence of noteworthy increases in serum alanine amino transferase and serum alkaline phosphatase indicate unaltered hepatocyte plasma membrane histoarchitecture and un-inhibited liver function. Values of serum total protein and plasma icterus index remaining within the respective normal range provided supportive evidence. Transient increases in blood urea nitrogen and serum creatinine were of no clinical concern; the glomerular filtration rate apparently remained unaffected in both treatments. From these observations, it is recommended that for routine short-term operations in canine surgical patients either pentazocine or LAS may be used, but for ultra short-term procedures LAS would be a judicious choice.
