Micro minerals have a great impact on animal's reproductive physiology and its imbalance causes various problems leading to lowered reproductive efficiency and resultant monetary loss to the dairy industry. Adequate micro minerals supplementation is required as most of the roughages, greens, concentrates and even most of commercial feeds available to Indian market are deficient in trace mineral elements. Often correcting an imbalance in mineral levels can sole a nagging problem by improving reproductive performance and health with little additional cost. As terrain and agro climatic area of India is quite diverse, so one therapeutic treatment may not be suitable for other regions. Hence there is a need to map of the various nutrient status in soil, fodder and animal, so that accordingly an area specific mineral may me supplemented.

Background: Fracture repair is one of most common procedure carried out by veterinary clinicians. Fracture healing most of the time associated with delayed union, non-union and mal-uinon. Therefore, the objective of this study was to evaluate the clinical, haemato-biochemical and radiological outcome in patients after implantation of β-tricalcium phosphate as a bone graft substitute to promote the fracture healing.Methods: Eight clinical cases brought to the clinics with femur fracture were divided into two groups viz. A and B, with four animals in each group. Femur fractures were stabilized with intramedullary pinning and β-TCP biomaterial and intramedullary pinning and β-TCP plus autologous bone marrow aspirate (BMA) composite in group A and B respectively. The efficacy of fixation was studied on the basis of clinical evaluation, haemato-biochemical and radiographical parameters on day 0 and on 7th, 15th, 30th, 45th and 60th post-operative day. Result: Excellent weight bearing was noticed in group B. The overall functional outcome in group B was better in comparison to group A animals. Haematological parameters viz. haemoglobin, packed cell volume, total leukocyte count and differential leukocyte count did not differ significantly within and between the groups. The biochemical parameters viz. serum calcium increased significantly (P less than 0.05) on 7th and 15th post-operative day. A significant reduction in serum alkaline phosphatase level observed on successive post-operative days in both groups. Radiographs of fractures treated in both the groups showed good reduction and fracture fixation, early signs of fracture healing in group B than group A animals. The size of callus formation was more in group A than group B. No any graft related complications observed during the study period. The β-tricalcium phosphate facilitated fracture healing and early ambulation of affected limb.

Background: Fracture is one of the common problems encountered in dogs. Fracture healing most of the times results into complications like delayed union, mal-union and non-union. To deal with these complications bone grafting is an important technique lying with clinicians. Methods: The present study was conducted on 14 clinical cases of dogs with femur fracture. After preliminary examination the dogs were randomly divided into two groups. In group A (n=8) fractures were managed by intramedullary pinning and in group B (n=6), fractures were managed by IM pinning and demineralised bone matrix (DBM) xenograft implantation at the fracture site. The efficacy of the treatment was assessed on the basis of clinical, hemato-biochemical and radiographic observation on day 0 and on 7th, 15th, 30th, 45th and 60th post-operative days. Result: The pain, lameness and weight bearing scores on the affected limb showed non-significant (P greater than 0.05) variations between the two groups on different post-operative intervals. The hematological parameters also varied non-significantly (P greater than 0.05) between the two groups. A significant (P less than 0.05) increase in the serum alkaline phosphatase values was observed upto 30th post-operative day in group B animals as compared to group A animals and thereafter it gradually decreases and return to normal level on 60th post-operative day in both the groups. Radiographic scores were better in group B dogs. Early radiographic signs of fracture healing were observed in group B dogs than group A dogs. No any graft related complications were observed during the study.
