The study was conducted to assess the effect of strain and stocking density on thermo-physiological response of broiler chickens. A total number of two hundred and sixteen (216) day old broiler chicks consisting of three different strains were used for the experiment. These strains were: Marshall, Ross and Abor-acre. The birds were randomly allotted to three different stocking densities which were 10, 12 and 14 birds/m2 respectively. Each treatment group was replicated twice in a 2 × 3 factorial design. Data were collected on thermo-physiological traits of the chickens twice in a week to avoid undue stress on the birds. Data were also collected on ambient temperature and relative humidity of the experimental area. Traits measured were; rectal temperature, pulse rate and respiratory rate. The data were subjected to analysis of variance (ANOVA) and there was significant interaction effect of strain and stocking density on physiological traits of the chicken. Thus, it is recommended that Marshall broiler chicken can be raised on stocking density of 14 birds/m².

A six years old entire Rottweiler bitch which was presented with the sole history of mild lameness and mild pain of the right forelimb was diagnosed as appendicular osteosarcoma (APOSA) based on its general condition, the physical and radiographic examinations supported by biochemical findings. The radiographic findings revealed an aggressive osseous growth, a “sunburst” appearance, a Codman’s triangle, the presence of a skip metastasis, mixed osteoblastic, osteosclerotic, osteolytic changes, erosion of the cortex of the affected humerus and rapidly growing metastases in the pulmonary system. There were serial elevations of the serum alkaline phosphatase levels during three consecutive occasions when it was assessed from 249 to 307 to 715 IU/L within eleven weeks as against the normal level of 1.0 to 114.0 IU/L. The anamnesis, clinical, radiographic and biochemical findings indicated a grave prognosis. No specific treatment or management protocol was administered as the client opted for none that was suggested. The bitch was eventually euthanized 11 weeks after its initial presentation due to its rapidly deteriorating health and a grave prognosis based on negatively progressive radiographic indices and a rising serum alkaline phosphatase profile. This presentation details the radiographic features recorded (in probably the first documented case of OSA in Nigeria) in an entire six years old Rottweiler bitch.
