Penelitian ini bertujuan untuk mengetahui hubungan musim dengan bobot lahir, panjang badan dan lingkar dada pedet sapi Brahman.  Materi penelitian yang digunakan adalah 450 ekor pedet sapi Brahman. Metode penelitian yang digunakan adalah survei dengan pengambilan data dilakukan secara sensus. Musim (X) dikelompokkan menjadi (1) awal musim kemarau, (2) akhir musim kemarau, (3) awal musim hujan dan (4) akhir musim hujan. Data dianalisis dengan analisis regresi sederhana. Hasil penelitian menunjukkan bahwa rataan bobot lahir 33,63 ± 4,20 kg, panjang badan 58,76 ± 4,15 cm dan lingkar dada 71,05 ± 3,42 cm. Hasil analisis menunjukkan bahwa musim berpengaruh sangat nyata (P<0,01) terhadap bobot lahir, panjang badan dan lingkar dada.  Nilai koefisien korelasi (r) bobot lahir, panjang badan dan lingkar dada masing-masing sebesar 0,306, 0,200, dan 0,206.  Nilai koefisien determinasi (r²) bobot lahir, panjang badan dan lingkar dada masing-masing sebesar 9,4 %, 4,0 %, 4,2 %.  Persamaan regresi dapat digunakan untuk menduga bobot lahir adalah Y = 30,41 + 1,21X,  panjang badan Y = 56,68 + 0,78X, dan lingkar dada Y = 69,29 + 0,66X.  Berdasarkan hasil analisis dapat disimpulkan bahwa bobot lahir, panjang badan dan lingkar dada pedet sapi Brahman mengalami penurunan pada awal hingga akhir musim kemarau kemudian mengalami peningkatan pada awal hingga akhir musim hujan.

The purpose of this research was to determine relationship the seasons with birth weight, body length and chest circumference of calf Brahman cattle.  The materials of this research were used 450 calf Brahman cattle. The research method used was survey with data collection by census. Seasons grouped into (1) early dry season, (2) end of dry season, (3) early wet season and (4) the end of wet season. The regression analysis showed that the average of birth weight is 33.63 ± 4.20 kg, body length is 58.76 ± 4.15 cm and chest circumference is 71.05 ± 3.42 cm. The analysis showed that the season was highly significant relationship (P<0.01) on birth weight, body length and chest circumference. Correlation coefficient (r) birth weight, body length and chest circumference were 0.306, 0.200, and 0.206 respectively. The coefficient of determination (r²) of birth weight, body length and chest circumference were 9.4%, 4.0%, 4.2% respectively.  The regression equation can be used to predict birth weight gained is Y = 30.41 + 1.21X, body length Y = 56.68 + 0.78X and chest circumference Y = 69.29 + 0.66X.  This study was concluded that the birth weight, body length and chest circumference of calf Brahman cattle has decreased at the beginning to the end of dry season and then increased at the beginning to the end of wet season.
