Feeding data about Newcastle disease Specific Immune Probiotic and Newcastle disease Vaccine used in young Laying hens
Test time: 30 days
Age of the young laying hens: 1 day old
Groups: Control group, Immune Probiotics group, Vaccine group, and Immune Probiotics & Vaccine group.
Attention: At the age of 7 days, Immunization by drinking except control group; And at the age of 21 days, Immunization by drinking again only for Vaccine group, and Immune Probiotics & Vaccine group.
Antibody titer of Newcastle disease data (log2)
| Groups | 14 days | 21 days | 30 days |
| Control group | 4.16±0.75a |
2.50±0.53a |
2.25±0.46a |
| Immune Probiotics group | 3.90±0.54a |
3.65±0.46b |
4.37±0.51b |
| Vaccine group | 3.83±0.75a | 3.25±0.46b | 3.80±0.53b |
| Immune Probiotics & Vaccine group | 3.83±0.75a | 4.67±0.74c | 5.40±0.75c |
There are different effection in Each group, the antibody titer level increased and keep longer time.
The result showed: There are maternal antibodies in young laying hens and the maternal antibodies of control group decreased with age.
At the age of 21 days and 30 days old, the antibody titer of control group decreased to 2.50 and 2.25, thus, it lost protection ability.
The effection of the groups with Immune Probiotics used are better than other groups.
Antibody titer of Newcastle disease data (log2)
| Groups | 14 days | 21 days | 30 days |
| Control group | 1985.83 | 2026.15 | 2257.72 |
| Immune Probiotics group | 2263.12 | 1808.26 | 3055.90 |
| Vaccine group | 2338.00 | 1969.55 | 3692.27 |
| Immune Probiotics & Vaccine group | 2458.38 | 2092.91 | 3939.14 |
The result showed: Newcastle disease Specific Immune Probiotics can increase immune level of intestinal mucosal . Because that sIgA content in manure and intestinal of the groups with Immune Probiotics used were effectively increased.
