Abstract

Infectious bursal disease (IBD) or known as Gumboro, is a disease that attacks chicken older than 3 weeks, caused by famili Birnaviridae virus. Gumboro in Indonesia was firstly reported in 1983 and until now is commonly found. Very virulent IBD virus causes high morbidity and mortality that can even reach 100%. Clinical symptoms are exhibited as sluggish chicken, dropped wings and cloacal pasting. At gross examination, the bursa was found swollen, with yellowish fluid or hemorrhagic 3 days after infection. The bursa will get atrophy from 7 days post-infection. Meanwhile, the non virulent IBD virus causes subclinical symptoms. Chicken that survived, became stunted or dwarfed. On gross and histopathological findings, the bursa Fabricius has mild lesion and will recover at 14 days post-infection. Diagnosis of IBD can be determined based on pathological observation, supported by immunohistochemical examination and laboratory confirmation of disease by agar gel immunodiffusion, polymerase chain reaction techniques, antigen capture enzyme linked immunosorbent assay and isolation. Detection of antibodies can be made by serum neutralization technique or enzyme linked immunosorbent assay. Prevention can be done by routine vaccination in the field when the maternal antibodies have declined. The review describes the etiology, epidemiology, pathogenesis clinical symptoms, pathological discription and control of the disease to improve the knowledge of poultry farmer or people who are interested in poultry health. Key words: Gumboro, etiology, epidemiology, pathology, diagnosis

Abstract

Pasak Bumi (Eurycoma longifolia Jack/ELJ) is frequently claimmed to increase expression of masculinity, including inducing the lean growth. This study was aimed to determine the effect of ELJ peptide supplementation on yield and physical composition of lamb carcasses. Sixteen Priangan rams about 1 year old with average weight of 30.43±1.41 kg were maintained in individual cages. The experimental rams were divided into 4 treatments i.e. T0, T1, T2, and T3. In T0, T1 and T2 treatments, the experimental rams were administered: 0, 1.5, and 3 mg ELJ peptide/kg BW, respectively. In the T3 treatment, the experimental ram were administered 1 mg/kg commercial product eurypeptide®. The ELJ peptide and commercial product were administered first in the morning prior to feeding. The experiment was conducted in a completely randomized design of four treatments and four replications. Data were covariance analyzed with an empty body weight as covariate for carcass weight and the right carcass weight as covariate for carcasses physical composition. The results showed that the weights of dissection body fat of T2 and T3 were lower than T0 (P < 0.05) and T1 (P < 0.01). Fat weight reduction was found in all parts of the carcass and more apparent in the fore saddle. Lean weights were higher ( P < 0.05) in T3 and T2 as compared to T1 and T0. The pattern of lean weight differed among treatments in the wholesale cuts that follow the total lean weight eventhough it was not significant. ELJ peptide treatment did not significantly affect either bone weight or wholesale cuts weight. In conclusion, T2 and T3 can improve carcass composition with equal ability.

Abstract

This experiment was conducted to determine the role of turmeric powder in lipid metabolism andits influence on the quality of the first quail’s egg. Sixty female quails were assigned into a completelyrandomized design with four treatments (levels of turmeric powder i.e., 0; 13.5; 27; and 54mg/quail/day) and each treatment used 15 quails. The treatment was conducted for 60 days. Parametersmeasured were proximate analysis and the quality of the first layed eggs. At the end of the experiment,serum cholesterol and triglyceride concentrations, abdominal and pectoral fat weights, and feedconsumption were measured. Chemical analysis showed that turmeric powder contained 7.97%curcumin. Supplementation of turmeric powder lowered serum cholesterol and triglycerideconcentrations, egg fat and protein contents, haugh unit and yolk index, but did not affect feed intake,abdominal and pectoral fat weights, egg weight, eggshell weight, eggshell thickness, and egg shellindex. However, quails supplemented with turmeric powder showed a variation in egg laying delayranging from 1 to 16 days. Quails supplemented with 54 mg/d turmeric powder had the highest follicleshierarchy. It was concluded that supplementation of turmeric powder with the level of 54 mg/quail/daydecreased lipid content of the egg and improved the other egg quality parameters.

Abstract

The study was conducted to evaluate the duration of road transportation during 4, 8 and 12 hours on body weight loss, hematological and biochemical responses of sheep. Twenty-four male Javanese thin tailed sheep were separated into transported group (T4, T8 and T12) and non-transported group (NT4, NT8 and NT12). Transportation (T) groups were transported for 4, 8 and 12 h in the same open pick up with 0.28 m2/head of loading density. Body weight, haematological and biochemical blood profiles were determined. The results showed that increasing of transportation duration significantly increased (P<0.05) body weight loss and decreased (P<0.05) hematocrit, cortisol and glucose values in the blood. However, these values were in the normal range of sheep well-being. In conclusion, transported healthy Javanese thin tailed sheep under good condition without feed and water access up to 12 h can tolerate to adverse effect of transportation without disturbing their welfare.

Abstract

An experiment was conducted to study the effect of curcumin supplementation inexpose monochromatic light on serum lipid concentrations of sexually mature female magelang duck. One hundred and ninety two female magelang ducks were assigned into a completely randomized design with a 4×4 factorial arrangement and each experimental unit was repeated 3 times, each with 4 female magelang ducks. The first factor was dose of curcumin supplementation consisted of 4 levels i.e., 0, 9, 18, and 36 mg/duck/day. The second factor was the color of monochromatic light consisted of 4 levels i.e., white, red, green, and blue colors. The data were analyzed by two-way ANOVA. The result showed that serum concentrations of triglyceride, cholesterol, very low density lipoprotein (VLDL), and low density lipoprotein (LDL) were lower (P<0.05) while high density lipoprotein (HDL) were higher (P<0.05) in experimental ducks supplemented with a curcumin dose of 36 mg/duck/day in variety of monochromatic light colors compared to control experimental ducks without curcumin supplementation. The curcumin doses of 18 or 36 mg/duck/day within red, green, or blue light had the potential to modulate lipid metabolism, as indicated by the increased serum concentration of HDL and the decreased serum concentrations of triglyceride, cholesterol, VLDL, and LDL of the experimental female magelang ducks.

Abstract

The liver of female poultry has a vital role as an organ for biosynthesis of the yolk precursor and has a greater chance of experiencing cellular damages. This experiment was designed to study the uses of curcumin and monochromatic light in suppressing liver destruction during the period of yolk biosynthesis in Magelang ducks. One hundred and ninety two female Magelang ducks were assigned into a completely randomized design with a 4x4 factorial arrangement.  The first factor was dose of curcumin supplementation consisted of 4 levels i.e., 0, 9, 18, and 36 mg.  The second factor was the color of monochromatic light consisted of 4 levels i.e., white, red, green, and blue. The results showed that hydropic and fat degenerations in the livers of Magelang ducks entering laying phase were still in a normal range. There was an interaction effect between curcumin and monochromatic light on the serum SGPT/GOT and liver MDA concentrations (P<0.05). Serum lipid concentrations positively correlated with the increased serum SGPT/GOT and liver MDA concentrations as indicators of liver damages. Supplementation of curcumin and the use of monochromatic light could reduce and suppress liver destruction and damage during laying period.

Abstract

Cholesterol is known to play an important role in nutrition of crustacean and function as a precursor for steroids synthesis, while neurohormone of serotonin could induce ovarian maturation in crustacean. Ovarian development of adult females Scylla serrata was induced by adding cholesterol in the diet and serotonin injection. This research was designed to study the effectiveness of cholesterol supplementation and serotonin injection in ovarian development. Broodstocks were stocked in nine experimental units in three fiber tanks. The fiber tank was equipped with sands substrate and flow through seawater system. The experimental crabs were assigned into a completely randomized design with a 3 x 3 factorial arrangement. The first factor was cholesterol supplementation in the diet with 3 levels (0, 0,5 and 1,0%). The second factor was serotonin injection with 3 levels (0, 5 and 10 μg/g BW). Samples of broodstock were taken every four days to evaluate the stages of ovarian maturity and parameters were used to evaluate the ovarian maturation stage are gonad index (GI) and oocyte diameter, concentration of estradiol 17β, yolk protein concentrations, and fecundity. Results showed that female crabs supplemented with 0,5% cholesterol and a combination of cholesterol 0,5% supplementation and injection serotonin with a dose of 10 μg/g BW had better reproduction development. It is concluded that ovarian development of Scylla serrata could be improved by cholesterol supplementation and serotonin injection. Key words: Cholesterol, serotonin, ovarian development, Scylla serrata   ABSTRAK Kolesterol diketahui merupakan nutrien spesifik yang berperan dalam sisntesis hormon steroid dan mengontrol reproduksi, sementara serotonin merupakan salah satu neurohormon yang dilaporkan dapat merangsang pematangan ovari dan pemijahan pada krustase. Penelitian ini bertujuan untuk mengetahui pengaruh tingkat pemberian kolesterol yang optimal dalam pakan buatan, serta dosis penyuntikan serotonin yang efektif untuk mempercepat proses perkembangan dan pematangan ovarium induk kepiting bakau Scylla serrata. Pemeliharaan induk dilakukan dengan menggunakan tiga buah bak fiber. Bak pemeliharaan dilengkapi dengan substrat pasir dan sistim air laut mengalir. Eksperimen menggunakan rancangan acak lengkap (RAL) pola faktorial, dengan 9 satuan percobaan. Faktor pertama, suplemen kolesterol didalam pakan dengan 3 tingkat dosis (0; 0,5; dan 1%) dan faktor kedua, injeksi serotonin dengan 3 tingkat dosis (0, 5, dan 10 μg/g bobot tubuh). Pengamatan terhadap tingkat kematangan ovari dilakukan setiap 4 hari sekali. Paramater pengambilan sampel meliputi  tingkat kematangan ovari, indeks gonad dan diameter oosit, konsentrasi estradiol 17β, konsentrasi protein yolk, dan fekunditas. Hasil penelitian menunjukkan bahwa induk kepiting yang disuplementasi dengan dosis kolesterol 0,5% dan induk kepiting yang mendapat perlakuan kombinasi, suplementasi kolesterol 0,5% dan injeksi serotonin dosis 10 μg/g bobot tubuh dapat menghasilkan perkembangan ovari yang terbaik. Jadi kolesterol dan serotonin dapat digunakan untuk meningkatkan perkembangan ovari. Kata-kata kunci: Kolesterol, serotonin, perkembangan ovari, Scylla serrata
