    THERAPEUTIC EFFECT OF EPIPLEURAL AND VISCERAL PROCAINE BLOCKADE IN PRIMARY INDIGESTION CASES OF BUFFALOES (Bubalus bubalis)
    (AAU, Anand, 1991) Shah, Dharmendra A.; Parsania, R. R.
    The cases admitted to Veterinary College Hospital, Anand and Ambulatory Clinic centres at Chikhodra, Gamdi and Bedva villages were studied and 50 oases of primary indigestion were selected for therapeutic trials. The cases were grossly diagnoses on the basis of history, clinical findings and faecal sample examination. These 50 animals were divided equally into five treatment trial groups via., (a) epipleural procaine blockade (b) viscera procaine blockade (c) conventional method supplemented with epipleural procaine blockade (d) conventional method supplement with visceral procaine blockade and (e) conventional method onl Clinical observations regarding overall behaviour of the animal, its expression, ruminal motility, heart rate, respiratiorate and rectal temperature were studied before and 48 hours aft the treatment in all the five groups of buffaloes. Haematologica parameters (Hb, PCV, TEC, TLC and DLC), biochemical parameters (blood glucose and BUN) and rumen fluid analysis (colour, odour, pH, protozoal motility and total volatile fatty acids concentrate were also studied before and 48 hours after the treatment. However, in all the parameters, the changes were found non-significant and remained within their normal physiological limits. Depending upon the efficacy and the rapidity with which the cases got cured, the present study has definately indicated that the procaine blockade was better than the conventional treatment. Among procaine blockades also, the visceral procaine blockade was found to be superior and practical method having wide field applicability. The present study was restricted to fifty clinical cases of primary indigestion only. But looking to the results achieved this visceral procaine blockade can be employed in more number of cases and also in variety of conditions, which may throw a light on some hidden efficacy of the same. So, further study is needed for better understanding of the blockade and i t s wide sprea uses in veterinary practices.

    EFFECT OF CLOMIPHENE CITRATE (FERTIVET FVT 300) ON SEXUAL BEHAVIOUR AND SEMEN QUALITY IN SURTI BUFFALO BULLS
    (AAU, Anand, 1991) Doshi, M. B.; Derashri, H. J.
    The present study was undertaken to evaluate the effect of clomiphene citrate (Fertivet FVT 300) on sexual behaviour, semen quality and quantity and level of testosterons in eight Surti buffalo bulls. The experiment was divided into three phases : pre-treatment, during treatment and post-treatment; each of eight weeks keeping equal number of bulls as control. Significant (P /0.05) effect of treatment was observed on reaction time, semen volume, total sperm count, total solids, total protein, citric acid, potassium and (P /0.01) serum testosterone level. Sustained significant effect of treatment was observed on citric acid (P /0.05) and serum testosterone level (P /0.01) during post-treatment phase. Significant (P /0.05) correlations due to treatment were observed between reaction time (negative), colour and consistency; (P /0.01) total protein, citric acid and initial fructose and testosterone. It was concluded that treatment with clomiphene citrate increased the testosterone levels in blood which reduced the reaction time and increased the sperm concentration to a threshold level and activity of accessory sex glands. Post-treatment effects sustained only for few weeks.

    (AAU, Anand, 1990) Purohit, Jayantilal Hargovind; JHALA, V. M.
    The present study was undertaken with a view to know the occurrence of Staphylococcus aureus In bovine milk In relation to species, managemental conditions, breed, method of milking, parity, stage of lactation and Involvement of the quarters as well as to observe the relationships among the certain characteristics, Including enterotoxigenicIty, of S.aureus. The isolates were also phage typed to know the possible origin. The milk samples were collected from the animals maintained at six different farms comprising of four GAU farms and two private farms. The cows were maintained at four farms whereas buffaloes were maintained at remaining two farms. A total of 925 milk samples (758 from cows and 167 from buffaloes) from the individual quarters of 234 animals comprising of 191 cows and 43 buffaloes were collected and processed for isolation and identification of S.aureus. Of these, 94 quarters (10.16 per cent) of 67 animals (28.63 per cent) revealed the presence of S.aureus. The incidence of S.aureus was more commonly encountered amongst the cows on animal basis (31.94 per cent) as well as on quarter basis (11.35 per cent) than those of buffaloes (13.95 and 4.79 per cent, respectively).

    PHYSIO-PATHOLOGY OF SUMMER STRESS IN LAYERS
    (AAU, Anand, 1989) GHODASARA, D. J.; Prajapati, K. S.
    The present study was made on layer birds kept at AICRP on poultry, Gujarat Agricultural University, Anand Campus, Anand. The study was conducted during extreme period of summer heat. For comparison, base level data were obtained by conducting similar study during comfortable environmental temperature of winter season .The experimental birds were divided into five groups with different housing and managemental systems. Samples like blood, serum, plasma and tissues were collected during morning and after-noon from each group and used for the study. Study was also made on natural cases of heat stroke and FLHS. Relationship of heat stress with incidence of FLHS as well as effect of housing system were also analysed. Concentration, of thyroid hormone in plasma was significantly decreased during summer season. Serum cholesterol level decreased during summer season as well as in after-noon than morning serum samples, suggesting lowered functioning of liver under heat stress. Relative weight of adrenal gland was increased during summer season, indicating increased activity of adrenal gland. Short term increase in temperature caused increase in the glucose level while, birds exposed for long period of high cyclic temperature (summer season) caused decrease in level of blood glucose. Activities of AXF and ALT increased during summer season. Thesealso increased in after-noon samples during summer season. The level of AKP was significantly higher in cage birds than deep litter birds during summer season, suggesting more stress of caging. Heat stress and housing systems did not cause any significant change in the level of total serum protein and sodium. Concentration of potassium and calcium was decreased in summer season. Potassium concentration was also decreased in after-noon serum sample in all the groups. Effects of heat stress and housing systems did not alter - the values of haemoglobin, PCV and R3C count. Total leukocytic count was significantly decreased during summer season. Further the after-noon blood samples also showed decrease in TLC in summer season. Absolute count of heterophil increased and lymphocytic count decreased during summer season. Number of heterophil was also increased in after-noon blood samples during summer season while, it was reverse for lymphocyte. Seasons and housing systems did not cause any significant change in the number of eosinophils and monocytes. Increase in environmental temperature directly correlated with the increase in H:L ratio and was found to be a good measure of stress to the chickens. Birds sacrificed in the after-noon during summer season showed mild fatty changes in liver and congestion in trachea and lungs. Severity of these lesions increased in the birds, died due to heat stroke. Birds under summer groups showed variable degree of hyperplasia of interrenal cells of adrenal gland. Thyroid acini were lined by flattened epithelium. More or less similar microscopic lesions were also observed in the birds, died due to heat stroke, but severity was increased. Amount of fat deposition increased in the liver samples, collected in the after-noon during summer season. Maximum mortality due to heat stroke was observed in the month of May. Increase in mortality due to FLHS was correlated directly to increase in the environmental temperature. Mortality due to FLHS v/as significantly higher in the cage birds than deep litter birds. Striking gross lesions in FLHS were highly friable and fatty liver leading to rupture and fatal internal haemorrhages. Liver sections stained with Oil Red 0 from cases of heat stroke and FLHS showed increased deposition of lipid in hepatic cells.
