    Studies on Lice Infesting Domestic Animals And Birds
    (Department of Parasitology, College of Veterinary and Animal Sciences,Mannuthy, 1979) Mohan, M C; KAU; Sathianesan, V
    In a study on the lice of animals and birds in and around Trichur and their control, cattle was found to be infested with Haematopinus, quadripertuous and linognathu vituli. Buffaloes with haematopinus tuberoulatus, goats with linognathus africanus and damalinia cappre dogs with heterodoxus longitatsus. Elephatnts with haematomyzus elephantis and poultry with Menacanthus stramineus menopon gallinae, Goniodes gigas and Lipeurus caponis. Their incidence and intensity were maximum in winter and minimum in summer. Their morphology has been described in detail. For their control, Nuven, Malathion and sevin were tried and Nuven (0.05 percent) was found to be superior to the other two insecticides, with 100 percent efficacy.

    Studies on growth response, feed efficiency and carcas characteristics of pigs reared up to different market weight on two dietary treatments
    (Department of Nutrition, College of Veterinary and Animal Sciences,Mannuthy, 1977) Ramachandran, P; KAU; Sivaraman, E
    A detailed investigation was carried out to study the growth rate, feed efficiency, carcass quality and economics of production of fattening pigs maintained on two dietary treatments differing in protein levels and reared upto three different body weights. Thirtysix weaner pigs of Large White Yorkshire breed belonging to the University Pig Breeding Farm, Mannuthy were distributed under two dietary treatments and divided into three groups 1, 11 and 111 of six animals each, the animals in the three groups being slaughtered at body weights of 55, 70 and 85 kg.respectively. Higher dietary protein level of 18 per cent promoted better weight gains in pigs during the initial period of their growth. Lowering of protein level in the finishing ration reduced the weight gain and feed efficiency of the animals. A dietary protein level of 16 per cent throughout the feeding period brought about linear increase in overall average daily gain at all body weights studied. Though the protein level does not seem to influence any of the carcass characteristics studied, the dressing percentage, carcass length, backfat thickness and eyemuscle area are positively correlated with body weights under both the dietary treatments. Fat constants are not affected either by protein levels or by live weights. The overall results obtained during the course of the present investigation indicate that the unit cost of production of fattening pigs is least at 55 kg live weight on the dietary treatment A having 18 – 16 – 14 per cent protein and at 85 kg live weight on the dietary treatment B having 16 per cent protein level throughout.

    Studies on the bacterial species associated with pneumonia in goats
    (Department of Microbiology, College of Veterinary and Animal Sciences,mannuthy, 1977) Madhusoodanan Pillai, R; KAU; Abdulla, P K
    A total of 214 specimens which inoculated 80 lung tissues, 55 nasal swabs, 43 tracheal swabs and 36 bronchial lymph nodes from goats with signs of pneumonia were examined during the course of this study. Out of these, 139 revealed the presence of different species of bacterial organisms. One – hundred and fifty six strains of various bacterial species were isolated and identified. The important species being Pasteurella multocida, Streptococcus pneumonia, Streptococcus Pyogenes, Corynebacterium pyogenes, Staphylococcs aureus, Klebsiella pneumonia and Escherichia coli. On experimental transmission study it was observed that P. multocida and Str. Pneumononiae were found to be lethal to mice and rabbits whereas C. pyogenes could produce only suppurative changes in omentum and liver. Intra tracheal inoculation of the cultures of P. multocida, Str.pneumoniae and C. pyogenes in goats have revealed the reproduction of mild pneumonic changes, but did not produce death due to pneumonia. As time advanced these earlier changes showed a tendency towards healing. Compared to P. multocida and Str. Pneumonia it could be said that C. pyogenes had produced more intense tissue reaction in the lung under identical conditions. In vitro antibiotic sensitivity studies of P. multocida, Str. Pneumonia and C. pyogenes to 11 chemotherapeutic agents were carried out. The agents included were ampicillin, bacitracin, chloramphenicol, erythromycin, gentamycin, kanamycin, nitrofurans, penicillin, streptomycin, tetracycline and triple sulfa. In the light of the results obtained it could be stated that the drugs of choice for P. multocida are nitrofurans, chloramphenicol and tetracycline. In the case of Str. Pneumonia, penicillin, chloramphenicol and bacitracin were found to be more effective and for C. pyogenes, ampicillin, chloramphenicol and penicillin showed cent percent sensitivity.
