Efek Proses Penyapihan Bertahap Dengan Pakan Starter Terhadap Respon Fisiologis,Tingkah Laku Dan Performa Produksi Pedet

Abstract

Penelitian ini bertujuan mengevaluasi perbedaan proses penyapihan bertahap dengan pakan starter terhadap respons fisiologis, tingkah laku, dan performa pedet pra-sapih. Penelitian dilaksanakan selama 35 hari menggunakan 6 ekor pedet Brahman cross (3 jantan dan 3 betina) berumur 3,5–4 bulan dengan bobot awal rata-rata 75,83±6,25 kg. Perlakuan terdiri atas durasi awal penyapihan 8 jam (P1) dan durasi awal penyapihan 12 jam (P2) yang ditambah 4 jam per minggu hingga mencapai 24 jam. Analisis data menggunakan repeated measurement dan t-test. Hasil penelitian menunjukkan bahwa perbedaan durasi awal penyapihan tidak berpengaruh nyata terhadap respons fisiologis pedet (P>0,05). Terdapat perubahan perilaku berdiri dan duduk antara minggu kedua dan keempat (P<0,05). Selain itu, pedet dengan durasi penyapihan awal 12 jam menunjukkan performa produksi yang lebih baik (P<0,05) dibandingkan dengan 8 jam. Dapat disimpulkan bahwa perbedaan proses penyapihan bertahap dengan pakan starter hingga 24 jam tidak memengaruhi respon fisiologis, tetapi berdampak pada perilaku jumlah bersuara , aktivitas duduk dan berdiri antar minggu. Durasi awal penyapihan bertahap 12 jam memberikan performa lebih optimal.

This study aimed to evaluate the differences in the gradual weaning process with starter feed on the physiological responses, behavior, and performance of pre-weaning calves. The study was carried out for 35 days using six Brahman cross calves (3 males and 3 females) aged 3.5–4 months with an initial average body weight of 75.83±6.25 kg. The treatments consisted of an initial weaning duration of 8 hours (P1) and 12 hours (P2), which were increased by 4 hours weekly until reaching 24 hours. Data were analyzed using repeated measurement and a t-test. The results showed that differences in initial weaning duration did not significantly affect (P>0.05) the physiological responses of calves. There were changes in standing and sitting behaviors between the second and fourth weeks (P<0.05). In addition, calves with a 12-hour initial weaning duration showed better production performance (P<0.05) compared with those weaned for 8 hours. It was concluded that different gradual weaning process with starter feed up to 24 hours did not affect physiological responses but influenced sitting and standing behaviors across weeks. A 12-hour initial duration of gradual weaning provided more optimal performance.
