Penelitian ini bertujuan unruk mengetahui performan produksi ayam. broiler jantan dan betina yang diberi perlakuan perratasan konsumsi energi selama empat dan tujuh hari. Dua races enam belas ekor ayam broiler jantan dan teoina strain Lohmann secara acak dibagi menjadi tiga kelompok perlakuan dengan '3 kali ulangan dan setiap ulangan rerdiri dari 12 ekor. Perlakuan yang dicobakan adalan: PI pemberian pakan ad libitum, ?2 dan P3 aibatasi konsumsi energinya dengan 1,49 x Bib/ d kcal ME hari selama 7 hari rnulai umur 7 hari dan 4 hari aula:umur 7 hari. Air ininum diberikan secara ad libitum. Eeoelah pembatasan, pakan dan air minum diberikan serara ad libitum sampai panen. Rancangan Acak Lenarap pola Faktorial digunakan dalam penelitian ini, dengan uji beda rerata Duncan's Multiple Range Tear. Hasil menunjukkan bahwa lama pembatasan konsumsi energi berpengaruh nyata (P<0,05) terhadap konsumsi paean dan pertambahan bobot badan, tetapi tidak berpengaruh nyata cerhadap bobot1 badan dan konversi pakan. denis kelanin berpengaruh nyata (P<0,05) terhadap perrambahan robot badan, bobot badan dan konversi pakan. Ayam broiler jantan menunjukkan pertambahan bobot redan yang lebih ringgi dibanding ayam broiler betina 1797,32c/ 'ekor vs 1648,7Og/ekor), bobot badan (1972, 1ig/ekor vs 1805,30g/ekor), dan konversi pakan yar.r lebih efisien ' 1,72 vs 1,84). Pembatasan konsumsi energi rr.elalui pembatasan pakan yang paling efektif adalah pada ayam. broiler jantan dengan lama pembatasan empat hari.

Phis experiment was conducted to investigate the effect of four and seven days restricted energy consumption of male and female broilers on production performance. Two hundred and sixteen broiler chickens of Lehmann strain were randomly devided into three treatments, in three replication with 12 birds each. The treatments were: PI fed ad libitum, P2 and P3 were restricted energy at 1,49 x EL2/ 3 kcal ME/day for seven and four days commencing at seven days of age. Water was allowed ad libitum. Feed were allowed ad libitum after the restriction period. The results showed that the duration of energy restriction had significant differences (P<0,05) on feed consumption and body weight gain, but had no significant differences on body weight and feed conversion. Sex had significant differences (P<0,05) on body weight gain, body -weight and feed conversion. Male broilers showed higher body weight gain than those the female (1797,32g/bird vs 1648,70g/bird), body weight (1972,22g/bird vs 1805,30g/bird), and the male had more efficient feed conversion ratio (1,72 vs 1,84). It could be concluded that the most effective energy restriction was on male broiler with four days restriction.
