Efficacy of spraying acaricides on infested sheep and goats with ticks.
2010
Muraleedharan, K. | Murthy, H. K. Siddaalinga | Paramsiviah, B. M. | Gopinathan, N.
The efficacy of two methods of spraying of acaricides on tick-infested sheep and goats was assessed. Two pyrethroid acaricides, 0.15% sumicidin and 0.20% butox were sprayed on individual animal one by one or on group of ten animals kept in small enclosures at a time, totally involving 40 sheep and 40 goats for each method. The efficacy, as seen from the total efficacy score (TES) of the former method of spraying, was found to be higher than the latter. But the advantages of the group spraying were that it saved the time in spraying and the quantity of acaricidal emulsion.

The hooded phenotype is one of the coat color phenotype seen peculiarly in the rat. The hooded locus showing autosomal recessive inheritance is mapped to chromosome (Chr) 14 and that the hooded phenotype receives modification by hooded-modifier gene showing the linkage to the hooded locus. However, a gene responsible for either the hooded or hooded-modifier gene is not yet identified. To clarify genetic control of hooded phenotype, we carried out genetic linkage studies using BN and LEA rats. For determination of phenotypic variation, we measured ratio of pigmented coat area in parental and their Fsub(1) and Fsub(2) rats. We, then, conducted a genome-wide scan on 152 Fsub(2) rats for linkage with ratio of pigmented coat area for the dorsal, ventral and total regions. A major quantitative trait locus (QTL), D14Got40, showing highly significant linkage contributing 70-90% of the variance for hooded phenotype was detected on Chr 14, which may be correspondent to the hooded locus. In addition, another QTL, D17Rat2, showing highly significant linkage was also detected on Chr 17 in dorsal region phenotype as well as a QTL showing suggestive linkage on Chr15 in ventral region phenotype. We, further, investigated a genome-wide scan for epistatic interactions and detected significant interactions between D14Got40 and D20Mit1, and between D14Got40 and D17Rat2 in the dorsal region phenotype. These results suggest that a major QTL in Chr 14, which is possibly correspondent to the hooded locus, mainly regulates the hooded phenotype with some modifier loci, two of which show epistatic interactions with the hooded locus.

2010
Lettry, V., Hokkaido Univ., Sapporo (Japan) | Sumie, Y. | Mitsuda, K. | Tagami, M. | Hosoya, K. | Takagi, S. | Okumura, M.
The objective of this study was to investigate the changes in synovial fluid concentration of collagen type II cleavage site (C2C) and pro collagen II C-propeptide (CPII), markers of joint cartilage degeneration and synthesis, respectively, in horses with intraarticular fracture or osteochondrosis dissecans (OCD), and to examine the relationship between arthroscopic findings and these biomarker levels. Synovial fluid was collected from 36 joints in 18 horses (6 fractures and 12 OCDs). Samples from contralateral normal joints, when available, served as controls (n=12). Concentrations of C2C and CPII were measured using enzyme-linked immunosorbant assays. Moreover, the severity of the cartilage degradation was graded arthroscopically in 16 horses, and the correlation between the C2C and CPII levels and the arthroscopic scores were investigated. Compared to the control, the concentration of C2C was increased in OCD joints but not in fracture joints, whereas the concentration of CPII was increased in fracture joints but not in OCD joints. Within each disease group there was no correlation between biomarker levels and arthroscopic findings. Therefore, although C2C and CPII have diagnostic potential further knowledge is required to provide accurate analysis.

Kumar, Ashish | Sharma, Ambika | Kumar, Ashok | Dev, Kranti
The mRNA from distal ileum of Indian goat was cloned and characterized after purification. cDNA was synthesized using goat ileal epithelial RNA, omniscript and sensiscript reverse transcriptase and amplified by Hotstart Taq DNA polymerase with primers designed by taking conserved regions of cattle enteric _Ò-defensin, cattle lingual antimicrobial peptide(LAP) and goat _Ò-defensin-2 sequences. The amplified cDNA of 253bp was, ligated to linearised TA cloning vector and transformed into XLblue strain of E.coli which was grown overnight at 37oC in a LB plate containing ampicillin, IPTG and X-Gal. The recombinant plasmid was isolated and digested with NcoI. The white colonies showed a release of 253bp insert. The sequence analysis showed 26, 16 and 5-nucleotide substitution having 85.6%, 91.3%, 97.4% homology with reported cattle EBD, buffalo EBD and goat BD2 mRNA respectively. The deduced amino acid sequence encodes for a 64 amino acid precursor peptide showing 12,18 and 4 amino acid substitution having 80%, 70.8%, 93.8% homology with buffalo EBD, cattle EBD and goat BD2 peptide respectively. Both nucleotide and amino acid sequence homology showed that the cloned sequence was closer to goat BD2.

The effect of addition of Melia azedarach (fruit), Pimpinella anisum (seed), Cuminum cyminum linn (seed), Murraya koenigii (leaves), Emblica officinalis (fruit), Allium sativum linn (bulb), Terminalia arjuna (bark), Sapindus trifoliatus (seed), Zingiber officinale (rhizome), Trigonella foenun-graecum (seed) at three dose level (1.5%, 2.0% and 3.0% of DM) on pH, dry matter and organic matter digestibility of feed was studied with rumen liquor of goat. There was no significant change in the in vitro fluid pH, showing no adverse effect of herb addition. The addition of all the herbs at 1.5% level had no significant (P 0.05) effect on in vitro dry matter and organic matter digestibility. There was slight improvement in dry matter and organic matter digestibility with the addition of Trigonella foenungraecum at 2% level as compared to control. At 3% level of addition of this herb, there was significant (P 0.05) increase in the in vitro dry matter digestibility (%) with Trigonella foenun-graecum (51.97) as compared to control (43.95). Similarly there was significant (P 0.05) increase in the in vitro organic matter digestibility (%) with Trigonella foenun-graecum (54.95) as compared to control (46.87) having with no addition of herbs. So Trigonella foenun-graecum (seed) at 3% dose level can be further explored in in vivo experiment to utilize it as a feed additive to increase the digestibility of feed in goats.
اظهر المزيد [+] اقل [-]Effect of Phyllanthus emblica on ceruloplasmin in bovine Staphylococcal mastitis.
2010
Sharma, Nitika | Mukherjee, Reena | Ingale, S.L. | Jadhav, Rabindra
Therapeutic and anti-inflammatory potential of aqueous extract of Phyllanthus emblica (Common name - Amla) was evaluated in mastitic cows. The milk Somatic Cell Count (SCC) and ceruloplasmin concentration was significantly (P0.05) higher in mastitic cows prior to treatment. The parameters of mastitic cows treated with P. emblica (group III) and with amoxicillin sulbactum combination (group IV) were compared to that of healthy cows (group I and II). Significant reduction (P0.05) in Somatic Cell Count (SCC) was observed in both the treated groups. The level of ceruloplasmin significantly (P0.05) reduced in group III and IV after treatment. Results of the present experiment indicate reduction of SCC and ceruloplasmin level in the mastitic animals treated with the P.emblica extract. The extract of P. emblica significantly reduced (P0.05) the udder inflammation and helped in lowering the concentration of inflammatory marker ceruloplasmin. Therefore P. emblica extract could be advised for the treatment of bovine mastitis.
اظهر المزيد [+] اقل [-]Evaluation of recombinant LipL32 and LipL41 antigens of Leptospira interrogans serovar Canicola by ELISA for serodiagnosis of bovine leptospirosis.

Sankar, Surya | Chaudhury, Pallab | Verma, Rishendra | Harshan, Hiron .M. | Srivastava, S.K.
Recombinant LipL32 and LipL41 outer membrane proteins of Leptospira interrogans serovar Canicola were produced, and used as a pooled antigen in enzyme-linked immunosorbent assay (ELISA) to detect leptospiral antibodies in bovine sera samples. The optimum concentration of the pooled antigen was found to be 50ng of each antigen per well by using known positive and negative cattle sera. Using a total of 500 bovine sera samples the sensitivity, specificity and accuracy of pooled antigen based ELISA as compared to microscopic agglutination test (MAT) were 100%, 88.1% and 91.6%, respectively. The results suggested that antigen in ELISA could be preferred for detection of all those cases, which might have remained undiagnosed by performing MAT.
اظهر المزيد [+] اقل [-]Comparative haematological response to different analgesic combinations in intravenous thiobarbiturate general anaesthesia in dogs.
2010
Rakshit, Sabita | Roy, Kabita
An early declining trend in haemoglobin concentration, concurrent with reduced total erythrocyte count and PCV% was observed with pentazocine or lysine acetyl salicylate (LAS) analgesic premedication in thiobarbiturate intravenous general anaesthesia in atropine-primed normal dogs. While the declining trend in PCV% persisted with pentazocine, it had abated at 1.5 hr with LAS pre-medication. No evidence of intravascular haemolysis or red cell morphological aberration was found. Alterations in the values of major haematological indices appear to be a passive consequence of volume changes in the splenic pulp: initial dilatation induced by the thiobarbiturate followed by spontaneous contraction back to original biometry. The observed early lymphopoenic-eosinopoenic response might reflect enhanced glucocorticoid titre during the anaesthetic stress.

Sharma, Neelesh | Maiti, S.K.
A study was carried out in 2161 quarter milk samples of 550 cows in Durg district Chhattisgarh. Out of 550 animals, 385 (70%) animals were found to be positive for sub clinical mastitis (SCM) by Modified White Side Test (MWST), 432 (78.54%) by Modified California Mastitis Test (MCMT) and 462 (84%) by somatic cell count (SCC). The quarter wise prevalence of sub clinical mastitis was 47.99%, 55.25% and 60.90% by MWST, MCMT and SCC respectively. Prevalence of blind teats was 1.77%. prevalence was highest during second and third lactations and at 5 and 6 years of age. Infection rate was higher during early and late stages of lactation. HF and Jersey cross bred cows were more susceptible than indigenous cows. Microorganisms isolated were predominantly Staphylococci. ABST revealed sensitivity to cefotaxime whereas most of the isolates were resistant to ampicillin.

The effect of vacuum packaging on microbiological quality of roasted chicken. Roasted chicken were subjected to two different type of packaging treatment i.e. aerobic packaging with low density polyethylene bags (con) and vacuum packaging using barrier bags (VP.). Microbiological analyses were done on 0th, 5th, 10th, 15th and 20th day at refrigeration temperature (4±1oC). Studies revealed that microbial counts in terms of total plate count, proteolytic count and yeast and mold count increased significantly (P0.05) with the advancement of storage period and were significantly higher (P0.05) for aerobically packaged product throughout the observation period however, yeast and mould count observed only on 10th, 15th and 20th day of observation period. Lactic acid bacterial counts of vacuum packaged product were significantly higher as compared to aerobically packaged sample.
