Abstract

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

Abstract

Zinc and Cu have important roles in growth and immune system, but their bioavailability are low due to the phytic acid content in poultry diet. This experiment was conducted in order to obtain the best combination of phytase, Zn, and Cu as growth stimulants for broiler fed diet containing phytic acid. Two hundred eighty eight Day Old Chicks unsexed were allocated into nine treatment diets with four replications (eight chicks in each replicate). The birds were raised up to 42 days old. Combination of the treatment diets were: R1 (positive control), R2 (negative control), R3 (R2 + 132.70 ppm ZnO), R4 (R2 + 286.16 ppm CuSO4), R5 (R2 + 132.70 ppm ZnO + 286.16 ppm CuSO4), R6 (R2 + phytase 1000 FTU/kg), R7 (R2 + phytase 1000 FTU/kg + 132.70 ppm ZnO), R8 (R2 + phytase 1000 FTU/kg + 286.16 ppm CuSO4 ), R9 (R2 + phytase 1000 FTU/kg + 132.70 ppm ZnO + 286.16 ppm CuSO4). The results of this research indicated that the phytase supplementation (1000 FTU/kg), ZnO (132.70 ppm), and CuSO4 (286.16 ppm) in poultry diet 1) improved the body weight and feed conversion, but did not significantly influence the feed consumption, 2) increased serum Zn, and 3) increased the alkalin and phosphatase activity.

Abstract

Mannan containing polysaccharides could be used as an alternative to replace antibiotics due to their capacity to block the colonization of pathogenic bacteria in the intestine of poultry. The aim of this study was to investigate mannan containing polysaccharides from palm kernel meal (PKM) and its inhibitory effect against Salmonella typhimurium. Hot water extractions were used to isolate mannan containing polysaccharides from cell wall of PKM. In vivo studies were conducted using broiler and layer chicks that were challenged orally with 104 cfu Salmonella typhimurium on third day. Split plot design was used as experimental design with strain as main plot and level of mannan polysaccharides as sub plot. The levels of mannan containing polysaccharides that were used consisted of 0 (R0); 1000 (R1); 2000 (R2); 3000 (R3); 4000 (R4) ppm, in term of total sugar. The results indicated that compared to the control group, feeding PKM containing mannan 4000 ppm decreased (P < 0.01) Salmonella typhimurium incidence. The addition of mannan did not affect feed consumption. On the contrary, the addition of 4000 ppm mannan gave significantly higher feed/weight gain ratio of the chicks (P < 0.05). The administration of feed supplemented with mannan from PKM did not influence weight gain of poultry. It is concluded that mannan from PKM can prevent the colonization of Salmonella typhimurium in poultry. Key words: palm kernel meal, mannan, Salmonella typhimurium, performance, poultry

Abstract

Duck meat is not preferred because its off-odor. Its off-odor is caused by lipid oxidation which preventable by antioxidant. Beluntas has antioxidant and anti nutrition. This research was designed to know the level of beluntas and feeding duration on performance, chemical, and duck's meat off-odor. Beluntas was given to 108 culling ducks, about 12 months old. The research used a completely randomized design with 3 x 3 factorial models, with 3 replicates. The factors were different levels of beluntas (0%, 1%, and 2%) in the ration, and feeding duration of each ration (3, 5, and 7 weeks). The data collected were analyzed using analysis of variance and Tukey's test. The results showed that no interaction was found between the two factors. Beluntas did not affect duck's performance. Feeding duration of each ration affected the fat and fatty acid content (P < 0.01) and TBARS (thiobarbituric reactive subtances) value of the meat with skin (P < 0.05). Beluntas level at 1% increased C18:0 (P < 0.05) and total (C18:2 and C18:3) (P < 0.052).  Beluntas levels at 1% and 2% reduced (P < 0.01) duck's meat off-odor and increased (P < 0.05) consumers preference. This research concluded that the inclusion of 1% beluntas for 3 weeks was effective to reduce duck's meat off-odor without negative impact on performance.
