Evaluasi Tingkah Laku Sapi Pedet Brahman Cross yang Dipelihara secara Feedlot

Abstract

Penelitian ini bertujuan menganalisis tingkah laku harian sapi pedet BX prasapih yang dipelihara secara feedlot. Penelitian menggunakan enam ekor pedet prasapih BX umur 1 sampai 2 bulan berjenis kelamin 3 jantan dan 3 betina yang dipelihara dalam kandang koloni. Pengamatan dilakukan secara langsung menggunakan metode interval scan sampling dengan teknik one-zero sampling pada pagi, siang, dan malam hari. Peubah tingkah laku yang diamati meliputi perilaku makan, berdiri, berbaring, perawatan diri, sosial, dan menyusu. Rancangan penelitian menggunakan split plot split in time dan data dianalisis menggunakan prosedur General Linear Model (GLM). Hasil penelitian menunjukkan bahwa tingkah laku makan dan berbaring nyata lebih tinggi (p < 0,05) dibandingka perilaku lainnya. Perilaku makan lebih banyak dilakukan pada pagi hari, sedangkan perilaku berbaring lebih dominan pada malam hari. Namun jenis kelamin tidak berpengaruh nyata terhadap peubah semua tingkah laku yang muncul. Terdapat interaksi antara jenis kelamin dan waktu pengamatan, dimana pedet pra-sapih betina menunjukan tingkah laku berbaring yang sangat nyata lebih tinggi dibandingkan tingkah laku lainnya (p < 0,01).

This study aimed to analyze the daily behavior of Brahman Cross (BX) pre-weaning calves raised under a feedlot system. The study used six BX pre-weaningcalves aged 1 to 2 months, consisting of three males and three females, which werehoused in a group pen. Behavioral observations were conducted directly using theinterval scan sampling method with the one-zero sampling technique during themorning, afternoon, and night. The behavioral variables observed included feeding, standing, lying, self-grooming, social, and suckling behaviors. The experimentaldesign used was a split plot split in time, and the data were analyzed using the General Linear Model (GLM) procedure. The results showed that feeding and lyingbehaviors were significantly higher (p < 0.05) than the other observed behaviors.Feeding behavior was more frequently observed in the morning, whereas lyingbehavior was more predominant at night. However, sex had no significant effect onany of the observed behavioral variables. There was an interaction between sex andobservation time, in which female pre-weaning calves exhibited a significantly higher proportion of lying behavior than the other observed behaviors (p < 0.01).
