| Judul Artikel | HUBUNGAN BOBOT AWAL KEBUNTINGAN DENGAN BOBOT LAHIR DAN BOBOT BADAN PEDET SAPI FRIESIAN HOLSTEIN UMUR TIGA BULAN DI BBPTU-HPT BATURRADEN (EARLY PREGNANCY WEIGHT AND BIRTH WEIGHT RELATIONSHIPS WITH CALVES WEIGHT OF HOLSTEIN-FRIESIANS AGED THREE MONTHS AT BBPTU-HPT BATURRADEN) |
| Abstrak (Bhs. Indonesia) | Penelitian ini bertujuan untuk mengetahui hubungan antara bobot awal kebuntingan dengan bobot lahir dan bobot badan pedet sapi Friesian Holstein umur tiga bulan. Penelitian dilakukan pada tanggal 5 Maret - 3 April 2016 di Balai Besar Pembibitan Ternak Unggul dan Hijauan Pakan Ternak Baturraden. Materi penelitian adalah catatan bobot awal kebuntingan sapi perah pada laktasi pertama dan pedetnya, bobot lahir dan bobot badan umur tiga bulan di BBPTU-HPT Baturraden yang diambil secara purposive sampling. Variabel yang diamati adalah bobot awal kebuntingan (kg), bobot lahir (kg), dan bobot badan pedet umur tiga bulan (kg). Metode analisis yang digunakan adalah analisis deskriptif dan analisis regresi. Bobot rata-rata awal kebuntingan di BBPTU–HPT Baturraden adalah 349,81±58,59 kg, bobot lahir 39,06±3,94 kg, dan bobot badan pedet umur tiga bulan 90,71±7,34 kg. Hubungan antara bobot awal kebuntingan dengan bobot lahir dinyatakan dalam persamaan Y=34,512+0,013X dengan nilai koefisien korelasi r= 0,194 dan nilai koefisien determinasi r2 =3,75%. Bobot awal kebuntingan memberi sumbangan sebesar 3,75% terhadap bobot lahir pedet. Bobot awal kebuntingan berpengaruh nyata (P<0,05) terhadap bobot lahir pedet. Hubungan bobot awal kebuntingan dan bobot badan pedet umur tiga bulan dinyatakan dalam persamaan Y=62,78+0,080X dengan nilai koefisien korelasi r= 0,637 dan nilai koefisien determinasi r2= 40,64%. Bobot awal kebuntingan berpengaruh sangat nyata (P<0,01) terhadap bobot badan pedet umur tiga bulan. Bobot lahir dengan bobot badan pedet umur tiga bulan dinyatakan dalam persamaan Y=44,60+1,180X dengan nilai koefisien korelasi r= 0,63 dan nilai koefisien determinasi r2= 39,69%. Bobot lahir berpengaruh sangat nyata (P<0,01) terhadap bobot badan pedet umur tiga bulan. Kesimpulan penelitian adalah bahwa 1) terdapat hubungan nyata antara bobot awal kebuntingan dengan bobot lahir pedet, 2) terdapat hubungan sangat nyata antara bobot awal kebuntingan dengan bobot badan pedet umur tiga bulan, dan 3) terdapat hubungan sangat nyata antara bobot lahir dengan bobot badan pedet umur tiga bulan. |
| Abtrak (Bhs. Inggris) | This research aims at determining the relationship between the early pregnancy weight of Holstein-Friesians cattle, birth weight and their calves weight aged three months. The study had been conducted from March 5 to April 3 2016 at Balai Besar Pembibitan Ternak Unggul dan Hijauan Pakan Ternak Baturraden. The research materials were the records of the cattle’s early pregnancy weight in the first lactation period and their calves, birth weight and the weight of three month calves, which were collected by purposive sampling from BBPTU-HPT Baturraden. The observed variables were Holstein-Friesian cattle’s early pregnancy wight (kg), birth weight (kg), and the weight of their calves aged three months (kg). The data which were analized with descriptive and regression analyses showed that the average of the cattle’s weight in early pregnancy was 349.81±58.59 kg, the calves’ birth weight was 39.06±3.94 kg, and calves’ weight at the age of three months was 90.71±7.34 kg. The relationship between the early pregnancy weight and the birth weight formed an equation Y=34.512+0.013X with a correlation coefficient r= 0.194 and coefficient of determination r2= 3.75%. The cattle’s early pregnancy weight contribut 3.75% to the their calves birth weight. The early pregnancy weight significantly effected (P<0.05) the birth weight. The relationship between the early pregnancy weight and the calves weight aged three months formed an equation Y=62,78+0,080X with a coefficient correlation r= 0.637 and coefficient determination r2= 40.64%. The early pregnancy weight very significantly effected (P<0.01) the calves weight aged three months. The relationship between the birth weight and the calves weight aged three months formed an equation Y=44,60+1,180X with a coefficient correlation r= 0.63 and coefficient determination r2= 39.69%. The birth weight very significantly effected (P<0,01) the three month-old calves’ weight. The conclusions of the research are that 1) there is a real connection between the early pregnancy weight and the calves birth weight, 2) there is a very real connection between the cattle’s early pregnancy weight and the three month-old calves’ weight aged, and 3) there is a very real connection between the the calves’ birth weight and their weight at the age of three month-old. |
