Aim: The objective of this study was to determine the prevalence of snail's intermediate host affected with larval stages of different trematodes. Materials and Methods: Snails were collected from ponds, tanks, ditches, canals and crop fields in and around Ranchi. They were transported to the laboratory in water containers and maintained in small aquaria, supplemented with natural food stuff. Then, snails were screened randomly for their infection with different trematodes by cercarial shedding method. Result: A total of 600 snails of different species mainly Indoplanorbis, Gyraulus, Lymnaea spp. and Vivipara were screened by cercarial shedding method out of which 44 (7.33%) were found positive for different trematodes cercariae. The percentage of infection in Indoplanorbis spp., Lymneae spp. and Gyraulus spp. were 7.22%, 8.60%, and 14.67%, respectively. Prevalence was higher in Gyraulus whereas, Vivipara did not show any infection with trematodes cercariae. Conclusion: The present study reveals that Indoplanorbis spp., Lymnaea spp. and Gyraulus spp. are common snails found in and around Ranchi. These snails act as intermediate hosts having infective stages of parasites. © The authors. Source

The present study was carried out to determine the molecular weight and mobility of the proteins present in the FMD virus. FMD trivalent vaccine and FMD infected serum samples were used for the study. The standard SDS-6H of known proteins was used for calculating the molecular weight of different proteins.The molecular weight of the FMD viral proteins 1 and 2 were 101 and 62 K Da and mobilities were 0.268 and 0.521 respectively. Seven distinct bands segregrated in control and FMD affected serum samples. The bands in the control sample from the top of the gel were identified as γ globulin, β globulin, unidentified protein, heptoglobin, albumin, α2 globulin and unidentified protein. Their molecular weights were 150, 140, 120, 100, 60, 48 and 33 K Da and mobilities were 0.094, 0.126, 0.186, 0.268, 0.536, 0.631 and 0.805 respectively. In the FMD affected sample, γ -globulin was undetectable but an extra band was noticed in the infected serum sample which was identified as the FMD viral protein. Source

The study was conducted on 54 semen samples obtained from 9 boars comprising 3 each of Large White Yorkshire, Tamworth and T & D (cross of Tamworth and Desi) by split sample technique to study the effect of different dilutors, genetic groups and hours of preservation on spermatozoa characteristics. The dilutors used were Kiev, Modena and lactose egg yolk (LEY). The sperm motility % was significantly highest in lactose egg yolk dilutor at all the hours of preservations. Irrespective of dilutors, the sperm motility% was significantly highest in T & D boars. Live sperm count was significantly highest in lactose egg yolk dilutor than Kiev and Modena during the hours of preservation in all the boar breeds. The difference in head abnormality % was nonsignificant in all the breeds and dilutors at all the hours of preservation except at 96 h. Highly significant effect of both hours of preservation and dilutors on the incidence of tail abnormality was noted during the study. The % of tail abnormality revealed an increasing trend with increase in the duration of preservation. On dilutor wise comparison, it indicated lower incidence of tail abnormality with lactose egg yolk dilutor at all hours of preservation. Therefore, it may be concluded that LEY diluter can be successfully used for preservation of boar spermatozoa at 15°C in a BOD incubator up to 96 h. Source

Data pertaining to 1662 Large White Yorkshire (LWY)-Desi crossbred piglets maintained at All India Coordinated Research Project on Pigs, Tirupati were used for the present investigation. Significant influence of period on age at I service (AFS), age at I farrowing (AFF), service period (SP) and farrowing interval (FI) and that of season on AFS, AFF and gestation period (GP) were observed. The overall least squares mean AFS, AFF, SP, GP and FI were 329.05 ± 2.9, 440.42 ± 2.80, 171.15 ± 2.97, 111.28 ± 0.26 and 283.87 ± 3.00 days, respectively. Period of farrowing and parity had a significant effect on all the litter traits studied. Genetic group had a significant effect on litter size at weaning and litter weight at birth while season of farrowing did not affect the litter traits studied. The overall least squares mean litter size was 7.59 ± 0.17 at birth and 6.94 ± 0.16 at weaning while the litter weights were 8.40 ± 0.18 at birth and 66.92 ± 1.42 kg at weaning. The genetic, phenotypic and environmental correlations of GP with litter traits varied from-0.49 to 0.69,-0.24 to 0.88 and-0.22 to 0.95 while the corresponding ranges among the litter traits were from-0.59 to 0.69, 0.62 to 0.88 and 0.09 to 0.95, respectively.

Transmission electron microscopic studies of eosinophil of horse, dog, pig and rabbit were carried out on six apparently healthy animals of each species. Ultrastructurally the eosinophils appeared round to oval in shape with few, short and narrow cytoplasmic processes in horse, oval with numerous long and wide cytoplasmic processes in dog and round with thin and broad small cytoplasmic processes in pig. While in rabbit it was round to oval in shape with long cytoplasmic processes. The nucleus had two to three lobes in all the animals. In all the four species it was observed that the heterochromatin was concentrated towards the periphery. Granules were mostly oval in outline and more or less similar in shape and size in horse while in dog the granules were rounded in shape and medium sized. In pig the double membrane bound cytoplasmic granules were roughly rounded to oval in shape and distributed throughout the cytoplasm. The granules in rabbit were mostly oval in outline and more or less similar in dimension. Cell organelles were clearly visible in the cytoplasm of horse while poorly visible in dog, pig and rabbit. © 2016, Agricultural Research Communication Centre. All rights reserved. Source
