Aim: To evaluate the feasibility of C-arm guided closed intramedullary pinning (simple Steinmann and end threaded) techniques for the stabilization of various canine long bone fractures.

Materials and Methods: The present study was conducted on 19 dogs with long bone fractures which were stabilized using simple Steinmann (Group I; n=6) and end threaded (Group II; n=13) pinning under C-arm guidance. Signalment, history of trauma, clinical examination, and hematobiochemical findings were recorded at the time of presentation. Radiography of the affected limb was carried out in two views to determine type and site of the fracture. Treatment of all the fractures was attempted using simple Steinman and end threaded pinning under the C-arm guidance. The success and failure of the closed technique were correlated with age, site, and type of fractures.

Results: The mean body weight and age of the dogs were 18.53±2.18 kg and 21.58±5.85 months, respectively. Early presented cases at a mean day of 2.84±0.54 were included. Out of 19 cases, it was possible to place implant successfully in 10 cases (success rate 52.63%) only. The remaining 9 cases had serious intraoperative complications like a misdirection of the pin after engaging the proximal fragment (n=3), missing the proximal fragment completely, and formation of the false tract (n=6). The majority of these complications were associated with younger age and proximal or distal third oblique fractures. High success rate of C-arm guided closed pinning was observed in midshaft fractures (75%) and transverse fractures (77.78%) in dogs of more than 1 year of age (77.78%). Simple Steinmann pinning was better feasible in a closed manner with a high success rate (66.70%) but also had implant related complications. Although, C-arm guided end threaded pinning was less (46.15%) successful, slightly tedious and time-consuming but had better implant stability than that of simple intramedullary pinning.

Conclusions: From the present study, it was concluded that C-arm guided closed pinning is recommended in transverse and midshaft fractures of the long bones in dogs older than 1 year of age. Furthermore, there is need to improve traction devices for enhancing the success of C-arm guided intramedullary pinning in dogs.

Aim: Detection of aflatoxin B1 in Livestock compound Feed and feed ingredients by high-performance thin layer chromatography (HPTLC).
Materials and Methods: Chromatography was performed on HPTLC silica gel 60 F 254, aluminum sheets by CAMAG automatic TLC sampler 4, with mobile phase condition chloroform:acetone:water (28:4:0.06). Extraction of aflatoxin B1 from samples was done as per AOAC method and screening and quantification done by HPTLC Scanner 4 under wavelength 366 nm.
Results: A total of 97 livestock feed (48) and feed ingredients (49) samples received from different livestock farms and farmers were analyzed for aflatoxin B1of which 29 samples were contaminated, constituting 30%. Out of 48 livestock compound feed samples, aflatoxin B1 could be detected in 16 samples representing 33%, whereas in livestock feed ingredients out of 49 samples, 13 found positive for aflatoxin B1 representing 24.5%.
Conclusion: HPTLC assures good recovery, precision, and linearity in the quantitative determination of aflatoxin B1 extracted from Livestock compound feed and feed ingredients. As more number of feed and feed ingredients are contaminated with aflatoxin B1 which causes deleterious effects in both animal and human beings, so there is a need for identifying the source of contamination, executing control measures, enabling better risk assessment techniques, and providing economic benefits.

Aim: The present study was conducted to evaluate the antidiarrheal effect of ethanolic extract of Holarrhena antidysenterica (Family - Apocynaceae) seeds against induced diarrhea in Wistar albino rats.

Materials and Methods: The extract was evaluated for castor oil and Escherichia coli induced diarrhea. Extract was given at 100, 200, 400 mg/kg body wt. orally in both protocols. Standard antidiarrheal Loperamide was used at 5 mg/kg body wt. orally in castor oil induced protocol, while standard antibiotic Gentamicin at 8 mg/kg body wt. intraperitoneally was used in E. coli induced diarrhea. In castor oil induced protocol, the percentage inhibition of defecation was calculated for each group, whereas in E. coli induced protocol, change in fecal consistency, and body weight was recorded for each individual rat for 3 days.

Results: The severity of castor oil induced diarrhea was reduced significantly (p<0.05) with H. antidysenterica seeds extract at 200 and 400 mg/kg body wt. which showed equivalent effectiveness like that of Loperamide treated groups. Similarly in E. coli induced diarrhea protocol, the mean change in body weight was significantly (p<0.05) higher in positive control, whereas no significant variation was observed in negative control, Gentamicin treated and H. antidysenterica treated group at 200 mg/kg and 400 mg/kg body wt., respectively.

Conclusion: The study concluded that ethanolic extract of H. antidysenterica seeds effectively controlled diarrhea and decreased the severity of clinical signs of castor oil and E. coli induced diarrhea in Wistar rats.

Aim: Sperm membrane cholesterol influences cryodamage during cryopreservation. The present study was carried out to evaluate the effect of varying cholesterol levels in Tris based extenders on the freezability of sexually healthy Malabari buck semen.

Materials and Methods: A total of 48 ejaculates from two adults healthy sexually healthy Malabari bucks were utilized for the study. The collected and pooled ejaculates were divided into four groups with Group I serving as Control - I, Group II and III were treated with 1 mg and 2 mg of cholesterol-loaded-cyclodextrin (CLC)/120 × 106 spermatozoa, respectively, and Group IV treated with 1 mg methyl-β-cyclodextrin (MβCD) served as Control - II. Manual freezing was carried out to cryopreserve the treated and control spermatozoa.

Results: Treatment of semen samples with CLC resulted in improved maintenance of sperm motility at pre-freeze and post-thaw stages of cryopreservation without affecting hypo-osmotic swelling response. Treatment of semen with 1 mg of CLC/120 × 106 spermatozoa was observed to be better than treatment with 2 mg of CLC/120 × 106 spermatozoa. In general, MβCD treatment was found to result in significantly lower sperm characteristics than those of Control - I and CLC treatment at pre-feeze and post-thaw stages and when incubated up to 4 h.

Conclusion: Cholesterol treatment of sexually healthy Malabari buck semen was found to hold promise for improving cryopreser-vability of spermatozoa.

Aim: In India, dairy industries are important for the livelihood of small scale farmers and dairy owners. Tropical theileriosis, mostly affecting dairy cattle and buffaloes is a major threat to dairy and related industries. Tropical theileriosis is caused by Theileria annulata, a hemoprotozoan parasite transmitted by Ixodid ticks of Hyalomma spp. In the present study, we examined the clinical signs, hematological parameters and flow cytometric profile of whole blood in 30 theileriosis affected crossbred cattle. The aim of our study is to analyze, in comparison with clinical and hematological diagnosis, whether flow cytometry based profiling of leukocytes could be used as better, quick and alternative method for diagnosis and screening of bovine tropical theileriosis in crossbred cattle.

Materials and Methods: In this study, we screened parasites in 30 peripheral blood samples from clinical cases of theileriosis by Giemsa’s staining technique in crossbred cattle. Hematological analysis was done to estimate hemoglobin (Hb) content, total red blood cell (RBC) count, total leukocyte count and differential leukocyte count. Further, flow cytometric analysis of whole blood was carried out to study leukocytes profile in affected cattle.

Results: Microscopic examination of stained blood films revealed the presence of piroplasms in erythrocytes and schizonts in lymphocytes. Hematological examination revealed significant (p<0.05) decrease of Hb percent (Hb %), reduced total RBC and total leukocytes, lymphocytosis, eosinopenia, and neutropenia compared to that of apparently healthy cattle. Flow cytometric profiling of leukocytes revealed the severe effect on shape, size, and granularity of leukocytes, marked decrease in granulocytes and 3-5 fold increase in lymphocytes count compared to clinically healthy cattle. Thus, in both methods, namely conventional and flow cytometric analysis, marked lymphocytosis and decrease in other blood cell counts were observed compared to clinically healthy cattle.

Conclusions: From results, it can be concluded that though conventional staining techniques and hematology are efficient in diagnosis of theileriosis, leukocytes profiling based on flow cytometry combined with clinical examination could be a quick, novel and alternative method for diagnosis and screening of clinical tropical theileriosis in crossbred cattle. Thus, there is potential to offer a flow cytometry based diagnostic service for tropical theileriosis in crossbred cattle.
