PENGAMATAN PERTUMBUHAN PEDET HASIL SILANGAN PERTAMA ANTARA SAPI SIMMENTAL DENGAN PERANAKAN ONGOLE PADA KONDISI PEMELIHARAAN TRADISIONAL
The objective of this observation was to obtain growth performance of the F 1 SIMPO kept under the traditional system from birth to 60 days of age. Sixty-two Ongole grade or PO in pregnancy (results from Simmental bull crossed with PO cow) were selected for observation. The observations were conducted in the sub-province region of Bantul, Special Region of Yogyakarta. The results of statistical analyzes on male at birth showed that the average of body weight, body length, and chest circle were
... 3.92±4.85 kg, 60.65±4.93 cm, 72.22±3.27 cm, and 72.62±3.68 cm, respectively; and female at birth were 31.48±3.32 kg, 58.52±3.76 cm, 70.56±2.53 cm, and 71.08±3.45 cm, respectively; on male at 60 days of age were 77.50±9.67 kg, 84.23±4.37 cm, 88.00±4.23 cm, and 100.38±4.95 cm; and female were at 60 days of age were 71.08±9.86 kg, 80.68±4.74 cm, 84.68±3.90 cm, and 97.04±5.78 cm. The average daily gain of weight, length, height from birth until 60 days of age, on male and female, were 720.60± 119.50 g/day and 660.00±129.20 g/day, 0.39±0.08 g/day and 0.37± 0.06 g/day, 0.26±0.06 g/day and 0.23±0.06 g/day, 046±007 g/day and 0.43± 0.07 g/day, respectively. A significantly different of sex (P<0.05) was found on body weight and body measurement, except chest circle at birth. But, no significant different of sex (P>0.05) was found on daily gain of body weight and body measurement from birth until 60 days of age. The SIMPO calf from Ongole grade cows of 5 years of age have body weight, body height and chest circle more superior than SIMPO calf from Ongole grade cows of 2, 3, 4, 6, and 7 years of age.
