Abstract
Osteodystrophia Fibrosa also known as bran disease, nutritional Secondary
Hyperparathyroidism (NHS) is a is a dietary calcium: phosphorus imbalance. The aim of
this study was to determine the occurrence of Osteodystrophia fibrosa along with
knowledge, attitude and practices of horse grooms in horses. The occurrence of
Osteodystrophia fibrosa (bran disease) was studied in three selected LGAs of Kaduna
State, Nigeria. The three LGAs were Igabi, Zaria and Sabon Gari LGAs. A total of 59
horses of both sexes consisting of 3 breeds (Argentine, West African Barb and Sudanese)
were used. Purposive and convenience sampling methods were used during the study. The
clinical signsand clinical parameters (Respiratory, pulse rate and rectal temperature)were
evaluated. The serum biochemical values, haematological values, faecal calcium and
phosphorous levels were also evaluated. The feed fed to the horses were also analyzed for
oxalate and phytate levels. The rate of occurrence of Osteodystrophia fibrosawas
74.6%.The knowledge, attitude and practice of the horse grooms were also evaluated.
Theclinical signs of Osteodystrophia fibrosa observed were enlarged facial bone, poor body
condition score and lameness. The vital parameters (RPT) were within normal values. The
haematological values of horses with Osteodystrophia fibrosawere all within normal
values. There was no statistically significant difference (p>0.05) between respiratory rate,
pulse rate, rectal temperature and haematological valuesof equine Osteodystrophia fibrosa
and non Osteodystrophia fibrosahorses. The serum calcium and phosphorus levels equine
Osteodystrophia fibrosa horses were 2.71±0.03 mmol/L and 1.26±0.08mmol/L
respectively.The parathyroid hormone of horses with and without Osteodystrophia
fibrosawas found to be 93.01±20.44 pg/ml and 38.9±3.50 pg/ml respectively. The values
were statistically significant(p<0.05)between the clinically and non-clinically diseased
viii
horses.Similarly, the oxalate and phytate levels in the horses‟ feeds 0.02 and 0.51m/100kg
respectively. The faecal calcium level of the horses from Igabi LGA had the highest values
of 75.89± 6.55mg/kg for the non-clinically diseased horses and 82.85±4.17mg/kg for the
clinically diseased horses and that the faecal phosphorus values for the clinically diseased
horses were also highest in Igabi LGA with values of 2801.76±212.51mg/kg. The high
level of calcium and phosphorus in the faeces of these horses could be as a result of high
oxalate and phytate in the feeds of the horses. The knowledge, attitude and practice of the
horse grooms showed they had a good understanding of the condition as85.7% of the
grooms knew the condition, 90.5% had good attitude while 71.4% had good practice
towards the condition. The study has shown that Osteodystrophia fibrosa exists in the study
area and that the nature of the horses‟ feeds could have something to do with the occurrence
of the condition. The study has further shown that there is no age predisposition for the
occurrence of the condition while the clinical and haematological valuesof the affected
horses do not seem to be adversely affected by the condition.it was suggested more horse
feeds should be examined to determine their oxalate and phytate levels in Nigeria.
