Abstract

Calcium and phosphorus deficiency in beef cattle is the common problem faced by smallholder. The study was conducted at the livestock Breeding Station, Department of Veterinary Services and Animal Industry, Tawau, Sabah. The aim of this study was to determine the status of blood calcium and phosphorus levels in grazing beef cattle and its effect on growth and fertility. Two hundreds ten heads of Brahman cattle with age range between one month and 163 months were used in this study. Blood samples were collected from coccygeal vein. Serum were harvested and tested for calcium and inorganic phosphorus levels using Calcium Reagent Set™ and Phosphorus Reagent Set™, respectively. The mean value for serum calcium and inorganic phosphorus of the 210 heads of Brahman cattle in the farm were 8.81 mg/dl and 5.35 mg/dl, respectively. There was a significant difference in serum inorganic phosphorus level between male and female Brahman cattle (X²=10.52, P<0.05). Serum inorganic phosphorus levels also varied significantly between young, grower, and adult Brahman cattle (X²=33.20, P<0.05). The average daily gain was calculated between the period of June 2008 and March 2009. The average daily gain was suboptimal in both sexes and among different age group. Calving interval for each Brahman cows was calculated. Calving interval among grazing Brahman cow was satisfactory. There were no major problems such as hypocalcemia, hypercalcemia, hypophosphatemia and hyperphosphatemia observed among the grazing Brahman cattle at the farm. Assesing the status of serum calcium and phosphorus in grazing Brahman cattle is important to farmer as it can indicate the health and reproductive status of the animals.
