Pengaruh Proporsi Pemberian Pakan pada Siang Malam Hari dan Pencahayaan pada Malam Hari terhadap Produksi Karkas Ayam Broiler

Adverse effects of feeding at high ambient temperatures during the day needs to be addressed. One of them is to reduce the proportion of feeding during the day and optimize feeding at night with cooler temperatures and cold environments. Giving light on broiler chickens depending on the management of maintenance depends on the intensity, duration of administration. The material used in this study was 300 chickens weighing 45.01 ± 4.67 g day old chicks (DOC) stain Ross CP 707 from PT. Charoen Pokphan. Chicken research is divided over the treatment of feed with two treatments and light treatments with three treatments each performed 5 replicates, each experimental unit consisted of 10 cows. The parameters observed were broiler feed intake, final body weight, carcass weight, carcass percentage. The data were processed and analyzed with an analysis of the range and tested by F-test, there was a significant effect (p <0.05) between treatments done Ganda Duncan Regional Test level 5%. The results of statistical analysis showed that the proportion of feeding during the evening and at night the lighting program, had no effect (P <0.05) for consumption, final body weight and carcass weight, and there are interactions on carcass percentage. The conclusions obtained in this study is the effect of the proportion of the feed with the old lighting at night had no effect on feed intake, final body weight and carcass weight but there are interactions on carcass percentage, increasing the proportion of feeding at night will increase the percentage of carcasses in line with the increase light at night
