Immunity Response of Gumboro and ND Vaccination Result which Given with Time Spacing in Broiler Chicken

An experiment was planed to know  the possibility of negative effect on Gumboro vaccination program. This program has a possibility to cause “Sick” condition on fabrious bursal of broiler chicken. From that case, it need time spacing for subsequent vaccination program, for instance ND vaccination program.  Time spacing is very importance to broiler chicken for recovering that “Sick” condition because of Gumboro vaccination effect. The purpose of his research was to know the best time spacing between Gumboro and ND vaccination program on broiler chicken. An experimental  method was used in this research, and the material used was 216 broiler chickens. A 3x4 factorial arrangement (Gumboro vaccination as factor A and ND vaccination  as factor B) with three broiler chickens per unit and six replicates of each treatment combination was used in the  research. Variables tested of  this experiment HI ND antibody titer, body weight  of 4 weeks old, and the symptom appeared after vaccination program. Anava was used to analyze the data obtained and used orthogonal polynomial for subsequent analysis. The research  results showed that the best time spacing was eight days and there was no symptom  appeared after  Gumboro  vaccination program. There were no significantly influence of vaccination treatments on broiler chicken health and body weight. (Animal Production 3(2): 67-73 (2001) Key Words: Vaccination, symptom, antibody

Maternal Antibody of DOC Pelung from Combine ND-Vaccinated Hen

A research entitled “Maternal Antibody of Pelung Day Old Chicken From Combine ND-Vaccinated Hen” has been done at Deddy Farm, Brebes. The materials were 25 hens and 5 cocks parental Pelung and 50 DOC (day old chick) hatched from those parent. Completely Randomized Design was performed in this experiment. The treatment consists of double dosages of inactive ND vaccine, active ND vaccine and cloned ND vaccine. The parameter was the immunity response on the parents and maternal antibody titer of the raised DOC. The results showed that; (1) one dosage of inactive ND vaccine combined with one dosage of active ND vaccine on Pelung chicken, yielding the best immunity response on the parent. The raised DOC also indicates the best maternal antibody titer, (2) giving two dosages of either inactive or active ND vaccine on the parent and the DOC could be analyzed alternatively to obtain a good immunityresponse, (3) the use of one dosage cloned-ND vaccine and one dosage of inactive or active ND vaccine on Pelung chicken yielding a low immunity response on the parent and the raised DOC.
