ABSTRACT
Broiler chicks were fed either mashed (MF) or pelleted (PF) ration commencing from day 21. Pelleting increased tboc consumption and weight gain throughout the experimental period. Feeding regimen had no significant effect on watei consumption (except from days 21 to 27), feed conversion ratios and mortality rate. Chicks fed pelleted ration were less active at 0900 hr and spent less time eating (at 0900 hr and 1400 hr) than their mash fed counterparts. While relative gizzard weight was not affected by feeding regimen, PF birds had higher abdominal fat deposition than those fed MF. Financial analysis showed a higher net profit for MF birds.
ABSTRAK
Anak ayam pedaging diberi makanan berbentuk dedak (MF) atau until (PF) bermula dari hari 21. Penguntilan meningkatkan pengambilan makanan dan pertambahan berat badan sepanjang tempoh kajian. Rejim pemberian makanan tidak mempengaruhi pengambilan air (kecuali dari hari 21 hingga 27), kadar pertukaran makanan dan kadar kematian. Ayam yang diberi makanan berbentuk until kurang aktif pada 0900 j dan meluangkan kurang masa makan (pada 0900 j dan 1400 j) berbanding iengan ayam yang diberi makanan berbentuk dedak. Sementara berat relatif hempedal tidak dipengaruhi oleh rejim pemberian makanan, ayam PF mempunyai pengumpulan lemak abdomen yang lebih tinggi berbanding ayam yang diberi makanan V1F. Analisis kewangan menunjukkan keuntungan bersih yang lebih tinggi pada ayam MF.
Key words: Broiler chickens, mash, pellet, growth, economics, behaviour
