ABSTRAK

Kajian lakuan maternal Landak Raya (Hystrix brachyura) di dalam kurungan telah dijalankan selama dua bulan dengan enam sesi pemerhatian, iaitu Sesi Pemerhatian 1-6 (SP 1 –SP 6). Kaedah pemerhatian yang digunakan adalah kaedah fokal berterusan dan sampel menggunakan seekor ibu dan anak Landak Raya. Lakuan yang telah dikenalpasti ialah rehat, menyusu, gerak, jilat anak dan makan. Terdapat perbezaan yang bererti (p<0.05) untuk aktiviti rehat dan menyusu bagi peratus masa yang diperuntukkan bagi SP 1 hingga SP 6. Manakala untuk aktiviti lain (gerak, jilat anak dan makan) didapati tiada perbezaan bererti (p>0.05) untuk peratus masa yang diperuntukkan untuk SP 1 hingga SP 6. Lakuan utama pada bulan pertama (SP 1 - SP 3) adalah rehat dan diikuti oleh menyusu, tetapi sebaliknya pada bulan kedua (SP 4 - SP 6) yang menunjukkan lakuan menyusu lebih tinggi dan diikuti oleh rehat. Ibu Landak Raya mempunyai enam puting susu yang terletak pada bahagian sisi lateral kiri. Anak Landak Raya lebih cenderung memilih puting susu di bahagian hadapan (T1 dan T2) semasa aktiviti menyusu berlangsung. Dalam kajin ini tidak dapat dikenalpasti waktu penceraian susu bagi anak Landak Raya kerana sehingga SP 6 berlangsung, lakuan menyusu masih berterusan, malahan kadar tempoh menyusu semakin meningkat.

ABSTRACT

Maternal behaviour study of captive Malayan porcupines (Hystrix brachyura) was conducted within 2 months where six observation sessions were conducted, from Observation Sessions 1-6 (OS 1- OS 6). Observation session was carried out using continuous focal observation method. A single mother and new born Malayan porcupine was used as a sample. Identified maternal behaviors were resting, suckling, moving, licking newborn and eating. Time spent on resting and suckling was different (p<0.05) among OS 1- OS 6. In contrast, other activities such as moving, licking newborn and eating, were no different (p>0.05) significantly among observation sessions. The dominant behavior in first month observation (OS 1 - OS 3) was resting and followed by suckling. Different pattern was demonstrated in the second month (OS 4 - OS 6) where suckling by the newborn was found the highest and followed by resting. The mother has six teats located in the lateral thoracic (three in right lateral and three in left lateral). The observation showed that newborn porcupine preferred to use the front teats (T1 and T2) during suckling. Weaning time cannot be determined during the observation period, due to suckling behavior and time spent on suckling continued and increased.
