<div>Background: Intramedullary pinning (IMP) is the most commonly used internal skeletal fixation technique. Threaded pins (also called Schanz Screws) provide a comparatively better holding strength than non-threaded tipped intramedullary pins. The present study was planned to evaluate and compare the efficacy of positive and negative profile end threaded intramedullary pins in the management of long bone fractures in dogs.&nbsp; 
 
Methods: Eleven clients owned dog suffering from fracture of long bones were randomly divided in to two groups. Animals of group I (n=5) and group II (n=6) were treated with end threaded positive and negative profile intra medullary pin, respectively. The intramedullary pinning was done using 3 to 5.5 mm diameter pins under general anesthesia, the time taken for surgery, size of end threaded intramedullary pin used in each case was noted down. Radiographs were taken preoperatively, immediately after fixation and then at regular intervals till signs of radiographic healing were evident.&nbsp; 
 
Result: There was no significant difference between the two groups in terms of time taken for fixation/surgery and in healing time, with a gradual improvement in weight bearing postoperatively in both the groups. There was mild periosteal callus formation in all the cases when observed radiographically and the pins were removed after radiographic healing was evident in an anticlockwise manner using Jacob&rsquo;s chuck and key, under mild sedation. There was no complication like implant failure or pin tract sepsis or pin migration or pin breakage in any of the cases of two groups. However, passing the positive profile end threaded intramedullary pin in distal fragment is comparatively smoother and easier as compared to negative profile end threaded intra medullary pin.</div>

<div>Background: Femur fractures are common in immature dogs. As compared to stainless steel, titanium implants are lighter and allow controlled micro-motion at the site of fracture that stimulates early callus formation by limiting stress shielding. Cited literature reports successful clinical use of titanium elastic nails for the stabilization of long bone fractures in young human patients; however, there is paucity of information on this technique is dogs. This study was planned with an objective to compare titanium elastic nails (TENS) and single end-threaded pin for the management of femoral fractures in young dogs. 
 
Methods: The study included 20 clinical cases (10 male and 10 female) of dogs suffering from distal femoral fracture with a mean&plusmn;SD age of 5.70&plusmn;5.60 month, body weight 11.09&plusmn;4.48 kg since 3.05&plusmn;2.35 days. The cases were divided into 2 groups; using TENS (n=10; group 1) and stainless steel end-threaded intramedullary pin (n=10; group 2).&nbsp; 
 
Result: Group 1 dogs demonstrated better fracture reduction score, early and uniform callus and better implant stability as compared to group 2, radiographically. Early weight bearing and minimum postoperative complications with better functional outcome including joint mobility was reported in group 1. In conclusions, TENS is superior fracture fixation technique for the repair of supracondylar or distal third femur fractures in young dogs with better functional outcome, minimal stiffness of stifle joint and early weight bearing, in comparison to single end threaded intramedullary pin.</div>

Background: The use of synthetic bone substitute,b-tricalcium phosphate (&beta;-TCP) as an osteo-conductive material and platelet-rich plasma (PRP) as an osteo-inductive material is the alternate strategies for replenishing bone loss. Thus, the present study was conducted to evaluate the bone healing efficacy of &beta;-TCP and PRP combination in dogs with long bone fracture repaired with threaded intramedullary pinning. 
 
Methods: Fifteen dogs were selected, which were allotted to two groups irrespective of age, breed and sex. In six dogs of Group I intramedullary pinning was performed, while in nine dogs of Group II &beta;-TCP and PRP was applied at fracture site after stabilising with intramedullary pin. Clinical and radiographic examinations were conducted preoperatively and postoperatively on 15th, 30th and 60th day. 
 
Result: The mean weight bearing and radiographic union scores were better in group II animals as compared to group I at different time intervals. The present findings suggest that &beta;-TCP and PRP effectively enhances the bone healing in dogs with long bone fracture.

Background: Dietary fiber can be effectively incorporated into processed meat products along with binders, extenders and fillers. Using millet in meat products can balance the enormous demand and supply for affordable, wholesome, dietary fiber enriched and healthful meat products. 
 
Methods: The duck meat sausages were developed by incorporating three different levels of roasted foxtail millet flour (FTMF) i.e. 5%, 10% and 15% and coded as T1 (5%), T2 (10%) and T3 (15%). The proximate composition, texture profile, colour profile and microbiological qualities of the control and treated sausages were estimated.&nbsp; 
 
Result: The moisture, crude protein, ether extract and calorie value of the sausages declined significantly (p&lt;0.05) with increasing levels of FTMF in the treated sausages. In the case of texture profile, a significant (p&lt;0.05) difference was observed in the springiness, hardness, chewiness and resilience (p&lt;0.05) of the sausages between the control and treated groups. However, no significant difference in cohesiveness was observed between the control and the treated products. The colour profile revealed no significant (p&gt;0.01) difference in lightness (L*), redness (a*) and yellowness (b*). TVC and TVPBC showed a significantly (p&lt;0.01) decreasing trend from control to treated products. However, the bacterial load increased during the storage for up to 15 days. No colititre, yeast, or mould were detected during the entire storage period.&nbsp;

Background: Tinospora cordifolia is a common climbing shrub that grows on other trees. It is native to India. Its root, stems and leaves are used in Ayurvedic medicine. 
 
Methods: Experimental animals (n=10) were equally divided into two groups of five animals each (average body weight 16.53 kg), designated as control (C) and treatment (C + T. cordifolia) group. A 60 day growth trial was conducted after giving adaptation period of 20 days. A 7-day metabolic trial was conducted towards the end of the experiment using standard protocol. Blood samples were collected at the end of study to determine biochemical and antioxidant profile. Rumen liquor samples were collected by oral intubation and used for quantification of microbial population. 
 
Result: T. cordifolia supplemented at the rate of 2% of DM intake in the total mixed ration of goat kids reduced the relative abundance of methanogens in the rumen, without any significant effect on nutrient digestibility, N balance, blood biochemical profile, cell mediated immune response and growth performance.

<div>Background: The industrial hub of Punjab, Ludhiana is polluted with heavy metals. The dairy animals experience stress due to pollution of heavy metals as well as the hot summer season. The stressors lead to disturbance in metabolic profile and affect milk production. The present study aimed at evaluation of detrimental effect of environmental heavy metal pollution on the metabolic profile of buffaloes during summer and winter seasons in Ludhiana district of Punjab, India. A total of 100 buffaloes were randomly selected from heavy metal exposed (n=60) and control area (n=40) during summer and winter seasons.&nbsp; 
 
Methods: The location of the experimental area surveyed on the basis of levels of heavy metals. The dairy farms are located in and around Ludhiana, Punjab were identified with levels of heavy metal above the permissible limits (FSSAI, 2010) viz. Chromium-0.05 &micro;g /ml; Nickel-0.02 &micro;g /ml; Arsenic-0.05 &micro;g /ml and Lead -0.05&micro;g /ml. The plasma samples were analyzed for metabolic profile. The water levels of heavy metals were below the permissible limits; therefore, it was taken as uncontaminated or control area. 
 
Result: Buffaloes of heavy metal exposed areas exhibited significantly (P&lt;0.05) higher levels of glucose, total cholesterol, triglycerides, BUN, creatinine, AST, ALT, GGT, ALP and CK levels as compared to control area. A significant (P&lt;0.05) decrease was observed in plasma total protein, albumin, A:G ratio, BUN: creatinine ratio in the buffaloes of exposed area as compared to the control area. However, significantly (P&lt;0.05) higher levels of plasma glucose, BUN, creatinine, AST, ALT, GGT, ALP and CK levels were observed during summer as compared to winter season in both exposed and control areas. Significantly (P&lt;0.05) decreased levels of plasma total cholesterol, triglycerides, total protein, albumin and BUN: Creatinine ratio were observed in the buffaloes during summer as compared to winter in both exposed and control areas. The Cr, Ni, As and Pb levels showed highly significant (P&lt;0.01) positive correlation with plasma levels of glucose, total cholesterol, creatinine, ALT, AST, CK and GGT. Highly significant positive relationship (P&lt;0.01) was observed among plasma levels of glucose, total cholesterol, creatinine, BUN, ALT, AST, ALP, CK and GGT whereas, plasma BUN had highly significant (P&lt;0.01) negative correlation with plasma total protein and A:G ratio considering both the areas together. Plasma levels of total protein showed significant (P&lt;0.01) negative correlation with all other metabolic profile constituents of both control and heavy metal exposed areas. Thus it may be concluded that the metabolic disturbance in heavy metal exposed buffaloes may have been mediated by heavy metal pollution.&nbsp;</div>

<div>Background: Lactating animals tend to lose body tissue reserves in support of lactation and move into a negative energy balance that leads to a higher incidence of metabolic disorders and compromised productive performance. Despite several efforts to assess the influence of parity on BCS and metabolic profiles in postpartum buffaloes, systematic information is less. The current study was conducted to evaluate the effect of parity on metabolic profile and changes in BCS in postpartum Surti buffaloes. 
 
Methods: In the present study conducted from September-2017 to May-2018, fourteen postpartum Surti buffaloes were selected and grouped based on parity as primiparous and multiparous (2nd to 5th lactation). The blood sample was collected from all the selected animals on the day of calving, 15th, 30th and 60th day post calving. Serum biochemical parameters viz., glucose, total protein, blood urea nitrogen (BUN), cholesterol and Non-esterified fatty acids (NEFA) were analysed. The body condition score (BCS) was assessed from the day of calving up to 60th day of the study at 15-day interval. 
 
Result: The study revealed that the BCS was significantly higher in multiparous buffaloes as compared to primiparous group. Among biochemical parameters, glucose was significantly higher in primiparous group as compared to their multiparous counterparts. Parity did not have a significant influence on serum total protein, BUN, cholesterol and NEFA. However, NEFA was slightly higher in multiparous group of Surti buffaloes. High NEFA and low serum glucose indicated a greater degree of negative energy balance in multiparous buffaloes due to higher milk output.&nbsp;</div>

<div>Background: Pearl millet (Pennisetum glaucum) is one of the major food crops in most of the arid and semi-arid cropping regions of India being the fourth most important cereal crop. Though rich in nutrients, presence of anti-nutrients reduces nutrient bioavailability in grains. The present study focuses on the impact of different processing methods on functional and nutritional profile of pearl millet flour (PMF). 
 
Methods: In present investigation, pearl millet grains were subjected to different processing treatments viz. roasting, blanching and malting and the post treatment effect on functional and nutritional profile of PMFs was studied. The influence of processing on functional properties, proximate, mineral and anti-nutrient composition of PMFs was studied. 
 
Result: Results revealed that processing treatments significantly affected the functional and nutritional profile of PMFs with reference to untreated PMF. Functional property assessment of PMFs depicted that, roasting enhanced the water holding capacity (371.24%) and swelling power (6.10%) of PMF while reduced the other functional properties. Blanching negatively impacted foaming capacity (3.52%) and stability (2.46%). Malting enhanced oil holding capacity (150.95%), emulsion capacity (38.51%) and stability (32.93%). Results for post treatment effects on nutritional profile of PMFs remarked malting as best in terms of nutritional enhancement with anti-nutrient reduction than roasting and blanching.</div>

Processing Driven Impact on Functional and Nutritional Profile of Pearl Millet

<div>Background: The negative energy balance around calving and in early lactation is the major cause of increased incidence of postpartum metabolic disorders, reduced milk production and impaired reproductive performance. This study was aimed to evaluate the effect of rumen protected choline, fat supplementation and Vit-E and selenium&nbsp; injections on plasma endocrine profile, postpartum productivity, fertility and economics in transitional Gir cows.&nbsp; 
 
Methods: Forty advanced pregnant multiprous Gir cows of an organized farm were randomly distributed into five equal groups (T1 to T5; n=8 each) and were fed and managed individually from 30 days prepartum till 60 days postpartum. Cows in T1 (control) group were fed basal diet, while cows in treatment groups received basal diet + supplementation of rumen protected choline-RPC @ 45 g/d/cow (T2), rumen protected fat-RPF @ 80 g/d/cow from -30 to +15 days peripartum and then @ 10 g/kg milk yield (T3), RPC and RPF in combination @ as above (T4) and&nbsp; Inj. E-Care Se(R) 10 ml i/m (Vit-E 500 mg and Se 15 mg) on days -30, -15, 0, +15, +30 and +45 peripartum (T5) along with blood samples for estimation of plasma levels of insulin, IGF1, PGFM, estradiol (E2), progesterone (P4) and cortisol. The puerperal events and fertility parameters were recorded till 10 months postpartum.&nbsp; 
 
Result: The fortnightly plasma P4 concentration decreased, while E2, PGFM and cortisol increased gradually and significantly (P&lt;0.01) from 30 days prepartum to day of calving and thereafter P4, E2 and cortisol remained basal or very low, while PGFM decreased till 45-60 days postpartum, overall and in all groups. The treatment effect was significant (P&lt;0.01) only for E2 and PGFM, with higher values of E2 in T3 and T4 groups and of PGFM in T1 and T2 than in T5 group. The insulin and IGF1 concentrations fluctuated insignificantly during prepartum phase with significantly lowest values till 15 and 30 days postpartum and thereafter only IGF1 increased significantly by day 60 postpartum. The treatment effect was also significant at some intervals with overall highest values of both the metabolic hormones in T1 followed by T5 and T2 than T3 and T4 groups. The uterine involution was significantly earlier in all treatment groups than in control. The first heat postpartum (days) was significantly earlier in group T5 (33.6&plusmn;3.4), delayed in group T1 (63.5&plusmn;9.5) and intermediate in Group T2 to T4. The conception rates postpartum were 50.0, 75.0, 62.5, 75.0 and 87.5% in groups T1 to T5, respectively, with significantly reduced service period (days) in T5 (96.3&plusmn;14.6), followed by T2 (137.3&plusmn;11.2), than T1, T3 and T4 groups (187 to 214 days). The overall net returns over feed cost of milk yield and reduced service period in T2, T3, T4 and T5 groups over control T1 were Rs. +15898, +6150, +7165 and +24060, respectively. The findings reflected the beneficial and economic role of RPF alone or in combination with RPC and of Se + Vit E supplementation on peripartum endocrine profile and improved postpartum fertility in Gir cows.</div>

<div style="text-align: justify;">This study aimed to investigate the influence of negative pressure on boar semen quality during liquid preservation at 17&deg;C. Semen samples from ten large white boars were collected and pooled, divided into four equal parts, and diluted with Modena containing 0.4% (w/v) of bovine serum albumin. The semen samples were placed in a closed container with valve, and a negative pressure was applied for 2&ndash;5 minutes using a vacuum pump with a barometer. The control group had no treatment, the P200 group was treated at 200 mbar, the P400 group at 400 mbar, and the P800 group at 800 mbar. During liquid preservation, sperm motility, total antioxidant capacity, and semen H2O2 content were analyzed every 24 h. The effective survival time of boar semen during preservation was evaluated. The results indicated that a suitable negative pressure decreased the effects on reactive oxygen species on boar sperm quality during liquid preservation compared with the control group. Among all the groups, the 400 mbar negative pressure group had the highest sperm motility, total antioxidant capacity, and the percentage of spermatozoa with high mitochondrial membrane potential. The P400 group also had semen H2O2 content than the other groups. A suitable negative pressure improves sperm quality by reducing oxidative stress and the respiratory metabolism of sperm, and the optimum negative pressure is 400 mbar.</div>
