Tujuan penelitian ini adalah untuk meningkatkan performan ayam petelur dan kandungan vitamin A dalam telur ayam yang diproduksi dari ayam yang diberi ransum berkadar asam fitat tinggi yang berasal dari dedak padi. Penelitian ini menggunakan 162 ekor ayam petelur strain ISA-Brown umur 18 minggu dan dipelihara sampai umur 33 minggu. Penelitian ini menggunakan rancangan acak lengkap (RAL) pola faktorial dengan 3 ulangan, masing-masing ulangan terdiri atas 6 ekor ayam. Faktor pertama (A) adalah suplementasi Zn dalam bentuk ZnO (0, 252 dan 567 mg ZnO/kg ransum), faktor kedua (B) adalah suplementasi enzim fitase (0, 300 dan 400 unit fitase/kg ransum). Data performan ayam petelur dianalisis sidik ragam (analyses of variance/ANOVA), sedangkan data vitamin A dalam telur dianalisis secara deskriptif. Hasil penelitian menunjukkan bahwa suplementasi ZnO maupun enzim fitase dalam ransum tidak mempengaruhi produksi telur hen day, konsumsi ransum, konversi ransum dan berat telur. Suplementasi ZnO maupun enzim fitase dalam ransum meningkatkan kandungan vitamin A dalam telur. Telur ayam yang diberi ransum dengan perlakuan suplementasi 252 mg ZnO/kg ransum mengandung vitamin A paling tinggi. Kata kunci : asam fitat, fitase, zinc, vitamin A, ayam petelur

Cholin (B-hydroxyethyl-trimethylammonium hydroxide) is a constituent of phospholipids, can interfere the metabolism process that affects the growth. Sometimes cholin in a diet does not meet the animal requirement because of its low availability. The objective of the research was to study the effect of cholin chloride supplementation in the diets on broiler performance. A completely randomized design with 4 treatments and 4 replications were used in the experiment on broiler chicks reared up to 6 weeks of age. The treatment diets were R1 (control), R2 (R1 + 750 mg cholin chloride/kg diet), R3 (R1+ 1,500 mg cholin chloride/kg diet), R4 (R1+ 2,250 mg cholin chloride/kg diet). All of the prestarter diets (0-2 weeks of age) contained isocaloric (3,000 kcal ME/kg) and isoprotein (24.8% crude protein). The starter-finisher diet (2-6 weeks of age) contained 3,000 kcal ME/kg and 20% crude protein. Supplementation of 750 mg cholin chloride/kg diet (R2) increased (P < 0.01) body weight gain and final body weight. Supplementation of 1,500 mg cholin chloride/kg diet (R3) and 2,250 mg cholin chloride/kg diet decreased (P < 0.01) body weight gain, final body weight, as well as feed efficiency. It was concluded that supplementation of 750 mg cholin chloride/kg diet (containing 1,956 mg cholin/kg in prestarter diet and 1,791.3 mg cholin/kg in starter-finisher diet) yielded the best performance of the broilers. Key words : cholin chloride, broiler chickens, performance

This experiment was conducted to study the effects of dietary addition Pluchea indica L. leaf meal on performances and meat cholesterol content of broiler. One hundred sixty two DOC CP707 strain were reared for four weeks in high stocking density of 15 birds/m2. The birds were fed experimental diets consisted of R1 (commercial feed + Vitastress), R2 (commercial feed + 2% P. indica leaf meal), R3 (commercial feed + 4% P. indica leaf meal), R4 (commercial feed + 6% P. indica leaf meal), and R5 (commercial feed + 8% P. indica leaf meal). The data obtained were analyzed using analysis of variance (ANOVA) and any significant differences were further tested using least significance difference (LSD) test. The treatment significantly increased (P < 0.05) final body weight, body weight gain, feed and water intake, and decreased (P < 0.05) feed conversion ratio. It is concluded that P. indica leaf meal could be added into a diet at the level of 2%. P. indica leaf meal addition at the level of 2% into a diet is also able to decrease the cholesterol content of broiler meat up to 8%.

Jatropha curcas meal (JCM) contains high crude protein (58%-60%), but it can not be used properly because of anti-nutritional contents known as curcin and phorbolesther. These components interferes protein metabolism and body protein synthesis. This study was conducted to evaluate the effect of feeding fermented JCM using Rhizopus oligosporus on broilers' performances. Ninety six of day old chicks of Ross strain broiler (initial body weight 45.6±1.7 g) were used and reared for five weeks. The treatments were: R0 (diet without JCM), R1 (diet contained 3% fermented JCM), R2 (diet contained 6% fermented JCM) and R3 (diet contained 9% fermented JCM). A completely randomize design with 4 treatments and 4 replications was assigned in this experiment. The data were analyzed using analysis of variance (ANOVA). The results indicated that feeding fermented JCM at the level of 3% to 9% in starter and grower-finisher broilers highly significant reduced (PR. oligosporus indicated no effective detoxification process in relation to the improvement of broiler performances.

Our previous study showed that the addition of water extracted beluntas leaf into drinking water could be used as an anti-stress and improved performance of broiler chicken. However, the addition was only up to 10% of drinking water. The objective of this experiment was to study whether the addition of sugar and water extracted beluntas leaf in levels higher than 10% of drinking water can give greater benefit on performances and meat cholesterol content of broiler. Two hundred sixteen DOCs CP707 strain were reared for four weeks in high stocking density of 15 birds/m2. The birds were subjected to experimental drinking waters with or without water extracted beluntas leaf (v/v) and sugar which is consisted of T1 (only drinking water), T2 (drinking water + commercial antistress), T3 (drinking water + 10% extract of beluntas leaf ), T4 (drinking water + 20% extract of beluntas leaf), T5 (drinking water + 40% extract of beluntas leaf), T6 (drinking water + 80% extract of beluntas leaf), T7 (drinking water + 40% extract of beluntas leaf + 1.6% sugar), and T8 (drinking water 80% extract of beluntas leaf + 3.1% sugar). The results showed that water extracted beluntas leaf addition higher than 10% significantly reduced (P < 0.05) body weight gain, final body weight, and increased (P < 0.05) feed conversion ratio. It is concluded that the addition of water extracted beluntas leaf more than 10% into drinking water cannot give greater benefit on performances as an antistress of broiler. Sugar addition cannot help the disadvantage due to the bitter taste of higher level of water extracted beluntas leaf addition.

The aims of this study were to determine the feeding effect of diets containing different ratio of ω-3 and ω-6 fatty acids and organic Zn on egg production and quality of Magelang duck. A total of 90 ducks of 20 weeks old were randomly divided into 18 experimental units by assigning a completely randomized design with 6 treatments and 3 replications. There were 6 dietary treatments, namely 1) ration without palm oil, fish oil and organic Zn with the ratio of ω-3 : ω-6 was 1: 5 (R0), 2) ration with the ratio of ω-3 : ω-6 was 1: 1.5 + 200 ppm organic Zn (R1), 3) ration with the ratio of ω-3 : ω-6 was 1: 3 + 200 ppm organic Zn (R2), 4) ration with the ratio of ω-3 : ω-6 was 1: 4.5 + 200 ppm organic Zn (R3), 5) ration with the ratio of ω-3 : ω-6 was 1: 6 + 200 ppm organic Zn (R4), 6) ration with the ratio of ω-3 : ω-6 was 1 : 7.5 + 200 ppm organic Zn (R5). Observation was carried out for 9 wk. The results showed that the ration containing the ratio of ω-3 : ω-6 = 1 : 3 and organic Zn (R2) produced significantly (P<0.05) the highest egg production and the lowest egg production was resulted by the dietary treatment without oil and organic Zn. Ration containing the ratio of ω-3 : ω-6 = 1: 3 and organic Zn (R2) significantly (P<0.05) decreased feed conversion ratio to the lowest value and it was significantly different as compared to R0 and R5. It can be concluded that feeding diet containing ω-3 and ω-6 with the ratio of 1:3 + 200 ppm organic Zn improves egg production without decreasing egg quality.

The beluntas (Piuchea indica L) leaf powder is one of the herbs species which contains antioxidants (flavonoid, vitamin C and beta-carotene), phytochemical and antinutrients. This study was designed to know the ability of the beluntas on the sensory of meat and duck egg without gave the negative effect on duck performances. The results showed that off-flavor's skinned meat duck were not affected, while off-flavor's duck and salted duck eggs are significantly reduced by 0.5% and 1% of beluntas leaf meal in the feed ration. Fatty acids of yolk eggs and duck meat were higher by giving beluntas leaf meal on the ration than without giving one. This showed that antioxidant on beluntas leaf meal could prevent lipid oxidation. TBA value of duck meat was the lowest by giving 0.5% of beluntas on the ration. The productivity such as egg production and feed conversion were the best by giving 1 °/o of beluntas leaf meal on the ration. Egg weight, quality of eggs; fat and cholesterol of yolk were not affected. A higher nutrient digestibilities (protein, energy, Ca and P) was obtained in duck eating 1.0% beluntas leaves (Psmall intestines. The numbers of ducks experiencing liver damage were the lowest in ducks consuming 1.0% beluntas leaves than those eating 0.5% beluntas

Jatropha curcas"meal (JCM) is very potential as protein source for poultry. The JCM contained high crude protein, i.e. 56,4-63,8% (without hull) and 22,39-31,41% (hulled JCM). JCM serves as a highly nutritious and economic protein supplement in animal feed, if the toxins and antinutrients contained in the JCM are removed. The toxic compounds isolated from jatropha seed include curcin, phorbolesters, and the antinutrients include antitrypsins, tannin, saponin, phytic acid, and high fiber. The objective of this research was to evaluate the effect of feeding fermented JCM on the performances of kampong chickens. In this study, tempeh fungi (fungi using in fermenting soybean) used to ferment the JCM. Two hundred kampung chickens were used in this experiment and reared from day old up to 10 weeks of age. The data analyzed with a Completely Randomized Design with 5 treatment diets and 4 replications, with 10 birds in each replicate. The experimental diets were: TO (the control diet, without Jatropha curcas meal), T1 (the diet contained 5°/o untreated Jatropha curcas meal), T2 (the diet contained 5% fermented Jatropha curcas meal + cellulase 200 ml/ton of feed), T3 (the diet contained 5°/o fermented Jatropha curcas meal + 1000 FTU phytase), and T4 {the diet contained 5% fermented Jatropha curcas meal + cellulase 200 ml/ton + 1000 FTU phytase). The results showed that there were no significant difference on the parameters observed due to the treatments. Feeding fermented Jatropha curcas meal supplemented with cellulase+ phytase{T4) yielded the final body weight and feed conversion ratio similar to those the control {TO) diet. There was no mortality observed in all treatments. Using JCM 5% in the diet is safe for the kampong chickens.
