    MOLECULAR CHARACTERIZATION OF DIFFERENT CHLAMYDIAE ASSOCIATED WITH VARIOUS INFECTIONS OF RUMINANTS
    (CSKHPKV, Palampur, 2011-07) Bhardwaj, Brijesh; Chahota, Rajesh
    Chlamydial infections have been reported previously among domestic ruminants from various disorders affecting reproductive system, respiratory system and digestive system in Himachal Pradesh, but the molecular characterization of various species/strains of chlamydiae involved has not been done yet, hence we conducted a molecular epidemiological investigation to detect the prevalence of different chlamydial species/strains in domestic ruminants in different parts of state, migratory tracts and in organized farms of Himachal Pradesh. To know the overall chlamydial prevalence in different disease conditions, total 404 samples were screened using Chlamydiales order specific primers based on 23S rRNA and family Chlamydiaceae specific primers based on VD2 region of ompA gene. Result of chlamydial screening showed that 93 (23%) samples, out of 404 samples were positive for chlamydiae, which showed the higher involvement of chlamydiae in various disease conditions. Out of 205 samples of reproductive disorders, 55 (26.82%) samples were showed chlamydial involvement. Among the cases of reproductive disorders, highest i.e. 38 per cent chlamydial association was detected in endometritis followed by 23 per cent in abortions. Out of 147 samples of pneumonia, 23 (15.64%) samples were found positive for chlamydial infection and from 39 samples of enteritis, chlamydial involvement was found in 33.33 per cent samples. Whereas, two samples of conjunctivitis were also found positive for chlamydial involvement. Molecular characterization and genetic variability studies of chlamydial species/strains detected among ruminants by PCR were done either by PCR-RFLP or by study of nucleotide sequence variation of ompA gene in VD2 region. Overall 57 PCR positive samples were characterized and out of which 39 (68.4%) samples were found C. psittaci, 16 (28%) samples were C. abortus, and two (3.5%) samples were found C. pecorum. From PCR positive samples, isolation of chlamydial strains was also attempted using 6 to 8 day old embryonated chicken eggs and isolation of chlamydiae up to 40.74 per cent could be achieved. Besides chlamydiae, involvement of other bacterial agents was also tested in samples from reproductive diseases. Various bacterial isolates like Brucella melitensis 2 (1.1%), Staphylococcus spp. 48 (26.37%), Streptococcus spp. 7 (3.84%), E. coli 47 (25.82%), Bacillus spp. 31 (17.03%), Klebsiella spp. 11 (6.04%), Arcanobacterium spp. 18 (10%), Pseudomonas spp. 13 (7.14%) and other bacterial species. 24 (13.19%) were isolated from different female reproductive disorders of the livestock. The results showed high prevalence of chlamydial infection among ruminants and involvement of multiple chlamydial species was detected in this study.

    STUDIES ON GENETIC AND NON GENETIC VARIATIONS OF ANGORA RABBITS REARED IN KANGRA VALLEY OF HIMACHAL PRADESH
    (CSKHPKV, Palampur, 2010-07) SHARMA, Loopamudra; Katoch, Sanjeet
    ABSTRACT This study was conducted to evaluate the phenotypic profiles, genetic and non genetic effects on wool production and reproduction traits in 588 and 361 German Angora rabbits maintained at Angora Rabbit Breeding Farm, Kandwari, Kangra (Himachal Pradesh) from 2000 to 2009 for reproduction traits and from 2000 to 2007 for wool production traits. The data was analyzed by Harvey’s least squares method of fitting constants. The overall least squares means were 4.62 1.64 k, 30.39 0.58 d, 58.77 35.10, 169.77 30.38, 181.00 21.30, 184.73 23.49, 594.22 67.13, 591.82 193.67 and 1185.96 202.96 g respectively for litter size at birth, gestation period, wool yield at first, second, third, fourth clip, first year, second year and cumulative yield. Year and season of kindling significantly affected litter size at birth, wool yield at first, third, fourth clip and first year yield. Gestation period, wool yield at second clip, second year and cumulative yield were affected by year. Heritability estimates were 0.09, 0.29 0.030, 0, 0.312 0.021, 0.27 0.017, 0.412 0.028 and 0.116 0.013 respectively for wool yield at first, second, third, fourth clip, first year, second year and cumulative yield. Genetic correlations of wool yield at second clip with second year and cumulative yield, wool yield at fourth clip with second year and cumulative yield and first year with second year and cumulative yield were negative. Wool yield at first clip with cumulative yield, second with third clip and third with fourth clip, first year, second year and cumulative yield were zero. Wool yield at second clip with fourth clip had the highest genetic correlation (1.226 0.398). Phenotypic correlations of second clip with second year and third clip with second year yield were negative. Second year and cumulative yield had the highest significant phenotypic correlation (0.942). Winter appeared to be the most favorable season for breeding of Angora rabbits. Improvement can be achieved with proper selection and improved management practices. Pure breeding stock of Angora rabbits can be introduced to maintain superior genotypes and variability.
