    Some Aspect of Mastitis in Buffaloes
    (Birsa Agricultural University, Ranchi, 1987) Praveen kumar; Dr. A.K.Sinha
    Hazarduous effect of mastitis on the socio-economic status of the farmers through the loss of milk and health of the animals leading to their culling and sacrifice is well established. With a view to asses the incidence and prevalence of mastitis in buffaloes in and around Ranchi in different farms with respect of daily milk yield, month of lactation, parity, types of infection and quarterwise infection by different indirect tests, the present investigation work was undertaken. To study these aspects of mastitis in buffaloes one organised farm, three unorganised farms and several private owners comprising the mixed group in and around Ranchi were taken for this study. Out of 259 milch animals 112 buffaloes were examined for incidence and prevalence of mastitis by indirect tests viz.trypsin inhibitor test, modified California mastitis test and bromothymol blue indicator card test and clinical observations were carried out to detect clinical, subclinical and chronic mastitis in these animals. To find out the causative organisms of mastitis and for their cure; culture, isolation, identification, sensitivity to different drugs, biological test for confirmations and drug trials for their treatment with different drugs were carried out in 29 buffaloes who were found positive for mastitis. Comparison of indirect tests for its suitability in detecting mastitis and efficacy of treatment for selection of drugs and line of treatment were carried out to have a better result of the research,

    Role of Reticuloendothelial System in the Immunopathology of Marek's Disease
    (Birsa Agricultural University, Ranchi, 1986) Madhurendu Kumar Gupta; Dr G. J. Jha
    It can be concluded from this work that the macrophages or the RE system has a pivotal role in protection against MD. Its depletion reduces the immunity to MD and stimulation leads to protection almost as much as by the vaccination itself. It remains to be found out if the vaccine also acts in the same way as activation of the RE system by the inert substances. Another interesting finding was that the LAI test could help in detection of the birds resistant or susceptible to MD. But its efficacy can differ from age to age. Hence its utility appears to be more in the third and fourth month of age when the disease is more likely to develop.

    Comparative Histological and Histochemical Studies on the Liver of Black Bengal Goats ( Carpa Hircus ) and Chotanagpur Sheep
    (Birsa Agricultural University, Ranchi, 1987) Massarat Khan; Dr. J. Prasad
    The liver capsule measured 28.08 in goat and 18.62 in sheep. It was surrounded by a layer of flattened mesothelial cells. It was composed of collagen, elastic and reticular fibras and occasional smooth muscle. The liver capsule indicated intense reactions for bound protein and DMA moderate to weak reactions for PAS positive substances, glycogen, bound lipid, acid mucopolysaccharides and calcium salts in both the species: however reactions for PAS positive carbohydrates and alkaline phosphatase ware of higher intensity in sheep, whereas, a negative reaction was noted for alkaline phosphatase in the liver capsule of goat. Reactions for natural fats, MA, acid phosphatase and ferric iron were found to be absent. Stromal connective tissue contained scanty amount of elastic, collegen fibres and abundant of reticular fibros. The fibroblasts vara comparatively more in the stronal tissues of the sheep. Stromal connective tissus showed intansa reactions for bound protein and DNA moderate to weak reactions for glycogen/ bound lipid, acid mucopolysaccharides and calcium salts in both goat and sheep. The PAS positive carbohydrates and alkaline phosphatase activity in the stromal connective tissus was of higher degree in sheep. Noutral fats, MA, acid phosphatase and forric iron were found to be absent in both the cases.

    Lactational Performance and Histo Physiological Changes of Udder Following Induction of Lactation in Goats
    (Birsa Agricultural University, Ranchi, 1987) Om Prakash MIshra; J.N.Pandey
    It is concluded from this study that hormonal induction of lactation using natural and synthetic sex steroids can bring about normal growth and development of the mammary gland in goats. The animals under induced lactation yield milk which is normal in composition and there are no untoward effects on the health of the animals as a result of hormonal treatment.

    Comparative Pathology of Pyrethroid and Organophosphate Pesticides Intoxication in Mice and Goats
    (Birsa Agricultural University, Ranchi, 1987) R.K. Tamang; G.J. Jha
    1.The clinical signs of chronic cypermethrin toxicity in mice appeared earliest in the Res depleted group and latest in RES activated group of mice. The cypermothrin treated normal mice fell between these two groups in exhibiting the clinical signs. Hyperesthesia, inco-ordination, irritation at the site of injection, paraplegia of hind quarters, respiratory distress, twitching of muscles, coma and death were observed in cypermathrin treated mice. On the other hand, the clinical signs of chronic quinalphos toxicity were dullness, depression, salivation, inco-ordination, prostration, coma and death. 2. The signs of chronic cypermethrin toxicity in goats were transitory in nature in two animals only which included hyperaesthesia, salivation and mild muscular tremors. Unlike cypermethrin the signs of chronic quinalphos toxicity in goats appeared early for a short period but the symptoms of toxicity in the terminal stages were more marked which included dullness, depression, salivation, diarrhoea, muscular tremor, posterior weakness, ataxia, dyspnoea, recumbency, groaning, coma and death .

    Study on the lever of Black Bengal Goats & Chotanagpur Sheep
    (Birsa Agricultural University, Ranchi, 1986) Malay Kumar Roy; Malya Kumar Roy
    Comparative histology and histochemistry of pituitary gland, pineal body, adrenal gland, thyroid gland and Leydig cells of testes were studied in the normal and vasectomized male goats. The normal goats were grouped under prepubertal (3-4 months), circunpubertal (6-7 months) and postpubertal (10-18 months) animals. The prepubertal vasec tomy was done at 3 months of age while postpubertal vasectomy was conducted at the age of 9 months. From vasectomized goats, the tissues were collected after 1, 3 and 9 months of operations. 5.1 PITUITARY GLAND (Glandule pituitaries) The capsule was mainly composed of collagen fibers with a few reticular and elastic fibers. The stroma was rich in reticular fibres. The sinusoidal capillaries were distributed the gland. Histochemically, the capsule and stroma were positive for PAS and acid mucosubstances. The capsule and stroma in the vasectomized goats did not differ from the normal goats. Para distalis adenohypophysis was composed of solid or tubular cell cord. The average cell density per m² area increased with the advancing age of the animals. Statistically the average cell density per m² area in the vasectomized goats did not differ from the corresponding normal values. Both orangeophil and carminophil were identified in the acidophil cells of the goat.

    (Birsa Agricultural University, Ranchi, 1987) Miss Massarat Khan; Dr. J. Prasad
    The liver capsule measured 28.08 u in goat and 产 in sheep. It was surrounded by a layer of flattened 10.62 masothelial cells. It was composed of collagen, elastic and reticular fires and occasional smooth muscle. The liver capsule indicated intense reactions for bound protein and DNA moderate to weak reactions for PAS positive substances, glycogen, bound lipid, acid mucopolysaccharides and calcium salts in both the species? However reactions for PAS positive carbohydrates and alkaline phosphatase ware of higher intensity in sheep, whereas, a negative reaction was noted for alkaline phosphatase in the liver capsule of goat. Reactions for neutral fats, RA, acid phosphatase and ferric iron were found to be absent. Stromal connective tissues contained scanty amount of elastic, collagen tires and abundant of reticular fibers. The fibroblasts were comparatively more in the stromal tissues of the sheep. Stromal connective tissues showed intense reactions for bound protein and DNA moderate to weak reactions for glycogen bound lipid, acid mucopolysaccharides and calcium salts in both goat and sheep. The PAS positive carbohydrates and alkaline phosphatase activity in the stromal connective tissue was of higher degree in sheep. Neutral fats, RIA, acid phosphatase and ferric iron were found to be absent in both the copes.
