    Managemental Effect On Some Of The Economic Traits And Carcass Quality in Swine Production Under Rural, Urban And Farm Condition
    (Birsa Agricultural University, Ranchi, 1989) Sinha Sunil Kumar; SinghRamadhar
    The present study was carried out on 138 weaned piglets consisting of 78 males and 60 females of Large White Yorkshire at Ranchi Veterinary College, Ranchi-7 as well as at Ranchi town and two villages namely Belangi and Dubolia. The average body weight of the piglets was 9.30 ± 0.12 kg. The duration of the experimental period was from weaning at 8 weeks up to 30 weeks of age. The objectives were to study the performance of the Large White Yorkshire under farm, urban and rural managemental condition and workout economies of production under different systems of management. The piglets were divided into two major groups under intensive and semi intensive system of management. The intensive system comprised of both farm and urban groups. The farm group was further divided into 5 subgroups A-I, A-II, A-III, A-IV and A-V .whereas, urban group was divided into 2 subgroups B-I and B-II. The piglets under semi-intensive which were distributed among farmers in two villages consisted of c-I and C-II groups. The allocation of floor space per pig under farm group was 0.67 m2, 0.48 m2, 0.56 m 2, 0.84 m 2 and 1.12 m 2 for groups A = I,A-II, A-III, A-IV and A-V respectively. The stocking density was 10, 14, 12, 8 and 6 pigs per pen for groups A-I to A-V respectively.

    Application of Modified Enzyme immunoassay Technique for Estimation of Progensterone in Blood and Mild to Monitor Reproductive Activity of Cows and Buffaloes
    (Birsa Agricultural University, Ranchi, 1988) Akhtar Mohammad Hasib; B.K. Singh
    Enzyme Immunoassay of progesterone in sera and milk samples of cattle and buffaloes was carried out during the present investigation. Investigation was done by indirect method of EIA using alkaline phosphatase and horse-radish peroxidase as label. In addition, amplifier system was also used in one of the groups. It was observed that with the use of amplifier the color development was more marked as compared to the use of either of the two enzymes. Secondly, values of progesterone, either in serum or milk were not different from the values when the two enzymes were used as label. Progesterone profile was estimated at regular intervals in sera and milk samples during oestrous cycle of cows, during early pregnancy and during par parturient period in cows and buffaloes. In addition, serum and milk progesterone values were estimated on alternate day during early pregnancy of cows from day 0 of oestrus to day 40. Ten cows were screened to find out the progesterone level in serum and milk during the complete oastrous cycle and it was observed that the duration of the cycle was of 20, 21 and 23 days in 2, 6 and 2 covs, respectively. The progesterone level on the day of oestrus in serun in all the three types of sexual cycles was low and a gradual increase in serum progesterone concentration was observed with peak on D 14, D 16 and D 19 in 20, 21 and 23 day cycles, respectively. Milk progesterone level also showed a similar pattern. In the adjusted oestrous cycle of 21 days the peak average progesterone value in serum

    STUDIES ON SOME MEAT PRODUCTION TRAITS IN CROSSBRED GOATS UNDER DIFFERENT SYSTEMS OF MANAGEMENT
    (Birsa Agricultural University, 1987) BHAT, ABDUL SALAM; Singh, R.A.
    The production cost per unit live weight gain was high in all the systems of rearing especially intensive and semi intensive, considerably high cost of all the inputs feed end fodder which excluding labour, constituted 75 per cent of the total contributed much to the increase in the production cost. The lower dressing percentage which varies from breed to breed had its influence on the carcass yield. The kids grazed entirely on pasture simulated a situation prevalent in the country side where supplemental feeding varied from zero to negligible quantity. But the cost of production though comparatively low did not seem so promising as to offer a better and lucrative proposition in absence of adequate supplement.
