A study was conducted in May 2003 to characterize plasma growth hormone (GH) pattern in growing mithuns (Bos frontalis), a rare semi-wild ruminant. Six mithun calves averaging 235 day of age and 124 kg were maintained in semi-intensive system and group-fed once daily. Animals gained at a mean rate of 0.54 kg/day, with individuals ranging from 0.34 to 0.66 kg/day. Blood samples collected at 15-minute intervals starting from 0600h for nine-hour period were assayed for plasma GH. Growth hormone patterns consisted of frequent pulses of varying amplitude. Growth hormone pulses occurred at an average frequency of 0.69/h, the rate did not differ markedly among mithuns nor hour of day. The magnitude of GH secretory pulses varied significantly among mithuns. Growth hormone peaks averaged 95.0 and 45.2 ng/ml in mithuns having the highest and lowest GH peaks, respectively. Peak and mean GH levels were associated positively (r=0.98, P Not Available |
