The aim of the study was to determine the effect sago waste in the rations on performance and carcass quality of duck as meat producer. The treatments of this experiment were R0 (0% sago waste/control diet), R1 (5% sago waste), R2 (10% sago waste), and R3 (15% sago waste). The experimental died contained 16% crude protein and 2900 kcal /kg metabolizable energy. Ducks used in this experiment was 6 weeks old male of ducks Mojosari and Pekin cross breed. The research design use was a complete Randomized Design using 4 feeding treatment, 5 replications, and 3 ducks per replication pens. The parameters measured were: feed intake, weight gain, feed conversion, carcass weight, carcass percentage and abdominal fat percentage. The results showed that the used of sago waste had no significant effect on feed consumption, weight gain, feed conversion, carcass weight, carcass and abdominal fat percentage. It can be concluded that used of sago waste up to 20% has no negative effects on performance and carcass quality of ducks.

The problem in using rice bran as animal feed is its low stability due to rancidity of hydrolysis and rancidity of oxidation. In addition, it quickly becomes clumpy and brings in insects, especially lice. The objective of this research was to determine the level of use of mangosteen peel flour in rice bran storage for one month on the physical and chemical qualities of rice bran. The research was conducted at the Laboratory of Animal Nutrition and Forage, Department of Animal Husbandry, Faculty of Agriculture, Pattimura University, Ambon. The materials used are rice bran from Gemba and mangosteen peel. The equipment used is a plastic sack with a size of 5 kg, a digital scale, a blender, a temperature and humidity measuring device. The research was conducted using a completely randomized design (CRD), 4 x 4. The observed variables included weight, color, odor, moisture content, crude protein, fat, and peroxide number. The follow-up test used if the treatments show significant differences is the Duncan test. The treatments tested were DKM0 = rice bran without mangosteen peel flour; DKM1 = rice bran with 5% mangosteen peel flour; DKM2 = rice bran with 7.5% mangosteen peel flour; DKM3 = Rice bran with 12.5% ​​mangosteen peel flour. The peroxide value of 7.95meq / kg is achieved when using 5% mangosteen peel flour, while at the 10% level it can suppress the smell until it becomes slightly rancid. The use of 15% mangosteen peel flour was not significant for color, fungus, protein moisture, fat and peroxide numbers.

To produce optimum carcass weight, broiler need an adequate ration which meet their nutrients requirement. This result in high feed cost which in turn increase cost of production. Therefore it is important to solve the problem by using non-conventional feedstuff such as agriculture by product or other ingredients.  The aims of this study were : 1). To examine the effect of giving coconut milky juice  and brown sugar water as drinking water on carcass weight and (2). To use by product of coconut milky juice  as drinking water. Experimental design used was complete randomized design, with three treatments and five replications. Each replication consists of  six chicken. The treatments were P0 (ration + plain water), P1 (ration + coconut milky juice (mature)) and P2 (ration + brown sugar water). Variables measured were: voluntary feed and drinking water intakes, carcass weight and percentage. Ration offered was commercial ration BR I produced by P.T Panca Patriot Prima Sidoarja. Chemical compositions of the ration were water content 12 %, minimum crude protein 21%, minimum crude lipid 6%, maximum crude fiber 5%,   energy 3065 kcal/kg, ash 6,5%, calcium 0.9 -1.1%, phospor 0.7 - 0.9%, antibiotic bacitracin Methylene, Disalcylate, Coccodistat Monensin. 90 DOC broilers strain CP 707 were used. An adaptation  period of 7 days allowed the animals to accustom to feed given and drinking water, and followed by 5 weeks measurement period. During the experiment the animals were fed twice daily at 07.00 and 16.00 h. The animal had free access to drinking water. The amount of drinking water and feed given was recorded daily. Drinking water and feed refusals were weighed every morning before the next feeding. Parameters measured were water and feed intakes, live and carcass weight, and carcass percentage. Drinking water and feed intakes were determined by subtracting  water and feed refusal from water and feed offered. Slaughtered weight were determined by weighing live animals after 10 hours fasting.  Carcass weight was determined by subtracting  non carcass  weight from slaughtered weight.  Analyses of variance were done using the General Linear Model (GLM). Least squares means and standard error were produced. Main effects were detected using LSD. Voluntary intakes were 1805.69 g, 1799.14 g, and 1806.66 g for P0, P1 and P2 respectively. The result shows that the treatments does not affect voluntary intake significantly (P > 0.05). However, broilers drank more (P < 0.05) coconut milky juice (mature) (P1/10287.2 ml), than plain water  (P0/9118.8 ml) or water contains brown sugar (P2/9081.8 ml).  Slaughter  and carcass weight of broilers are  1701.33 g,1849.40 g, 1847.27 g and 1263.87 g, 1386.00, 1379.90, for P0, P1 and P2 respectively.  Statistical analysis  show significant differences (P < 0.05) in slaughter and carcass weight among the treatments in which those parameters are higher for broilers received P1 and P2 than that of P0. Carcass percentage is the ratio of  slaughter  and carcass weight, which are 74.27%, 74.93 and 74.71 for P0, P1 and P2, respectively.  No differences in carcass percentage were obtained (P > 0.05) among the treatments. In conclusion, the present study has shown that giving 1 % brown sugar in drinking water and coconut milky juice (mature) as drinking water has no significant effect on voluntary intake and carcass percentage. However, giving brown sugar water and coconut milky juice (mature) affect drinking water consumption, slaughter and carcass weight.

This study aims to examine broiler chickens’ response to brown sugar with different levels of turmeric in drinking water. The study was conducted in the Department of Animal Husbandry housing unit, Faculty of Agriculture, Pattimura University, using 90 unsexed Cobb strain broiler chickens aged 1 day, randomized into three treatment groups following a completely randomized design with a 3 x 5 directional pattern. The treatment consisted of P0: feed + drinking water without brown sugar and turmeric, P1: feed + 2% brown sugar and turmeric 10 grams/1 liter of water; P2: feed + 2% brown sugar and turmeric 20 grams/1 liter of water. BRI commercial chicken feed is produced by PT. Japfa Comfeed Indonesia Tbk is used in this study. Feed intake, water intake, body weight gain, and feed conversion were measured variables. The data were analyzed using Anova and continued with the BNT test if there was a significant difference. The administration of brown sugar with different levels of turmeric in drinking water showed no significant difference (P>0.05) for all the variables measured. However, the application giving is recommended 2% brown sugar and 20 grams of turmeric in drinking water.Key words: Feed intake, Body weight gain, Brown sugar, Curcumin, Broiler
