Abstract

Day old chick in the first week of their life got the immunity from maternal antibody / immunoglobulin trough egg yolk. Hens with high antibody titer will decended the immunoglobulin to their harvest trough egg yolk. The research studied the capability of antibody anti H5N1 from egg yolk to neutralized H5N1 AIV.  Twenty hens were devided to five group, one group as  a control group were unvaccinated group and four other groups were vaccinated with H5N1 AI inactive vaccine produced by several  Indonesia vaccine company. Four H5N1 AI inactive vaccines code VS1, VC1, VV1 and VM1 were vaccinated twice to group 2, 3, 4 and 5. A week after second vaccination the egg were collected and analyzed the antibody titer against H5N1 AIV  by hemagglutination test using H5N1 AIV field isolates as standard virus (NG and LW)). The egg yolk were contain high antibody titer (above 26) collected and tested against H5N1 AIV field isolates NG and LW by serum neutralization test.  The result showed that H5N1 AIV NG isolate were able to neutralized by antibody anti H5N1 AIV from egg yolk produced by hens vaccinated with VS1, VC1, VV1 and VM1, but LW isolate were able to neutralized by showed that H5N1 AIV NG isolate were able to neutralized by antibody anti H5N1 AIV from egg yolk produced by hens vaccinated with VS1, VC1, and VM1.  It’s concluded that hens were vaccinated with H5N1 AI inactive vaccine were able to protect their off spring against H5N1 AIV from the field by transferred maternal antibody trough the egg yolk with titer above 26.

Abstract

Bay leaves contain flavonoid active compounds including quercetine and fluoretine having antioxidative and antimicrobial properties. Bay leaves can be given as feed additive to improve body metabolism in animals. This study was aimed at assessing the effects of the inclusion of bay leaf solution in drinking water on the performance and carcass quality of male MA ducks. Seventy-two male one-day-old MA ducks were allocated into battery cages (50 cm length, 50 cm width, 78 cm height). The ducks were fed commercial rations containing 21-23% CP and 2820-2920 Kcal/kg ME and given drinking water containing bay leaf solution (LDS). A completely randomized design with 3 treatments and 6 replicates of 4 ducks each was used. Treatments consisted of drinking water containing no LDS (R0), drinking water containing 4% LDS (R1), and drinking water containing 8% LDS (R2). Measurements were taken on production performance and percentages of carcass parts. Results showed that th einclusion of LDS in drinking water gave significant effects (P<0.05) on body weight gain but not (P>0.05) on all carcass composition parameters. It was concluded that the inclusion of LDS in drinking water up to 8% resulted in a mean body weight gain of 194.88±10.88 g/head/day but did not affect the percentages of carcass and its parts including breast, wing, and thigh. It was recommended that LDS be included by up to 8% in drinking water of male MA ducks for optimal body weight gain.

Abstract

Native chicken is a species of fowl that is usually consumed by people in Indonesia. Most various of native chicken bred are new strains, i.e Merawang chicken, Kampung Unggul Balitbang (KUB) chicken and IPB D-1 chicken. High-quality chicken shall be produced from superior breed through artificial insemination by micropipette. A micropipette is a pipette tool with high accuracy and precision to collect cement when performing an artificial insemination. This research is performed to test the internal and external quality of egg which involves egg yolk index (IKT), haugh unit (HU), eggshell weight and egg weight of 3 types of native chickens that artificially inseminated by a micropipette of various doses using 108 female native chickens aged 50 weeks and 6 males native chickens aged 24 months. The treatment was applied to the object with details of 36 female KUB and 2 males KUB, 36 females Merawang and 2 males Merawang, and 36 females IPB D-1 and 2 males IPB-D1. The quality test of eggs used 72 eggs which consists of total each type of chicken are 24 eggs. Data were analyzed using Completely Randomized Design (CRD). Factors that affect internal and external quality are age, genetics, health, environment, storage time, and feed. Research could be followed to conduct hatchability tests on the eggs produced from this study to trace an effect on egg hatchability in various types of native chickens.
