Nutrient Digestibility and Performance of Male Pelung Chicken Fed Rice Bran-Based Ration Supplemented with Lime (Citrus aurantifolia) Juice
Abstract: Rearing Pelung
chicken in Indonesia, in general, uses a ration with a high proportion of rice
bran, even up to 60%. Considering the high contents of fiber, lignin, and
phytic acid, feeding a high portion of rice bran will decrease nutrient
digestibility. This study was aimed to evaluate the effect of lime juice supplementation
of a rice bran-based ration on the utilization of nutrients in male Pelung
chicken. Sixty four of 12 weeks old male Pelung chickens were used in the
present experiment and assigned into a completely randomized block design. The
treatments were supplementation of the ration with lime juice at the levels of
0, 1, 2, and 3 mL/100 g. Parameters measured were feed and nutrients
consumption, protein, fat, and fiber digestibilities, apparent metabolizable
energy (AME), rate of passage, feed conversion ratio (FCR), and daily body
weight gain. The results showed that the
supplementation of lime juice in the ration did not affect feed and nutrient
consumption, but significantly (P<0.05) increased the digestibilities of
protein, fat and fiber, AME, rate of passage, FCR and daily body weight gain.
However, supplementation of 2 or 3 mL
lime juice in the ration resulted in similar values of AME, and protein, fat
and fiber digestibilities, and both levels of supplementation produced better
protein and fat digestibilities, and AME when compared to the other treatments.
It could be concluded that supplementation of 3 mL lime juice in the ration
increased the digestion processes in the gastrointestinal and increased daily
weight gain of male Pelung chicken.
