“…There were no clinical symptoms of calcium deficiency with any of the cows. Calcium values obtained by Shirley et al (1968) for cows grazing pangolagrass as the only source of this element averaged 9.8, 10.5, 11.3, and 10.4 mg per 100 ml plasma in March, June, September, and December, respectively.…”

“…The low individual hematocrit values for the five lots ranged from 31.1 to 41.8% and the high values from 67.8 to 85.0%. Braun (1946) fount1 that hematocrit values for cows 18 to 30 months of age were 34.4 -C 0.6% while Shirley et al (1968) obtained average values from 48.2 to 52.1% for different groups of cows on improved pasture. The effect of management and supplement feeding on the four blood components are shown in Table 4.…”

Individual blood samples showed variation in components between range cows and for the same animal at different seasons. Adiusted means values for all blood samples were: phosphorus and calcium per 160 ml plasma 5.2 and 11.4 mg, respectively; hemoglobin 11.6 gm per 100 ml blood; and hematocrit 54% packed cells. Blood calcium, hemoglobin, and hematocrit levels were significantly influenced by season and breed of cow. There was a highly significant season effect on blood phosphorus, a significant breed)(season interaction, and a non-significant effect when values were averaged for all seasons.

Twenty-four yearling 11-month old Nellore steers initially weighing 180 kg were assigned to three treatments in a randomised complete block experiment lasting 392 days. Animals grazed continuously either Yaragua grass (Hyparrhenia rufa) or Yaragua/Stylo legume (Stylosanthes guianensis) and received the following treatments: A) Control, Yaragua plus common salt, B) Yaragua/Stylo plus common salt, and C) Yaragua/Stylo plus dicalcium phosphate/common salt (1:1). Mineral consumption in the three groups averaged 52 g per animal day-1. At 13 months daily liveweight gains/steer were 0.182, 0.409 and 0.483 kg for treatments of Yaragua, Yaragua/Stylo, and Yaragua/Stylo plus dicalcium phosphate/common salt mixture. Daily liveweight gains per ha were 0.488, 1.289, and 1.522 kg steer-1 for Yaragua, Yaragua/Stylo plus common salt and Yaragua/Stylo plus dicalcium phosphate/common salt. Steers receiving a legume (stylo) in the diet more than doubled weight gains (P less than 0.05) compared to controls with dicalcium phosphate further (P less than 0.05) increasing these gains.
