The Effect Of Maternally-Derived Antibodies Against Antibody Production In Vaccinated Piglets With Modified-Live Porcine Reproductive And Respiratory Syndrome Virus Vaccines, Sunit Mebumroong

Chulalongkorn University Theses and Dissertations (Chula ETD)

The humoral antibody responses following vaccination with different lineage of modified live genotype 2 porcine reproductive and respiratory syndrome virus (PRRSV) vaccines (MLVs) were investigated. Moreover, the mortality and growth performance in pigs were observed. Twenty-four pigs with high maternally derived antibody (MDA) levels (SN titer ≥ 8) from each PRRSV positive Herd 1 and Herd 2 were allocated to the H1, H1-1, and H1-2 groups (Herd 1) and H2, H2-1, and H2-2 groups (Herd 2). Twenty-four pigs with low MDA levels (SN titer <8) were allocated to the L1, L1-1, and L1-2 (Herd 1) and L2, L2-1, and L2-2 groups (Herd 2). Twenty-four pigs from the negative herd (Herd 3) were allocated to 3 groups: N, N-1, and N-2 groups. The H1, H2, L1, L2, and N groups were unvaccinated. The H1-1, H2-1, L1-1, L2-1, and N-1 groups were vaccinated with MLV (Ingelvac® PRRS MLV) at 2 weeks of age. The 5 other groups: H1-2, H2-2, L1-2, L2-2, and N-2 groups were vaccinated with MLV2 (Prime Pac® PRRS MLV) at 2 week of age. The antibody responses were measured by ELISA and serum neutralization (SN). The mortality was not observed in all vaccinated groups. Additionally, pigs with high MDA levels from the H1 and H2 groups did not exhibit the mortality throughout the study. ADG in pigs vaccinated with each MLV1 and MLV2 was significant higher than that in unvaccinated pigs. However, pigs vaccinated with MLV2 showed the highest values of ADG. Seroconversion was observed in all vaccinated groups with no significance difference in antibody titers between pigs with low and high MDA levels. However, pigs with low MDA levels showed the earliest and highest antibody level post vaccination. The highest SN-titer against MLV1 isolate and MLV2 isolate was observed in pig from the L1-1 and L2-2 groups, respectively. The field PRRSV-2 isolates: THA_SP/RB_S1/P1/0120-18 and THA_WC/RB_F165/20-22, the SN titers against these isolates were not observed in vaccinated groups. These results indicated that MDAs might not affect the immune response post vaccination. PRRSV-2 MLVs reduced the mortality and improved growth performance of pigs in the endemically PRRSV infected herds. Although, the vaccine was changed in weaning pigs, the antibody responses were detected post vaccination in both pigs with low and high level of MDAs. Moreover, the genetic similarity between vaccine and field virus was not related to the protection. Vaccine selection should depend on the induction of immune response and protection against heterologous PRRSV infection.

Herbal Feed Additives Containing Tannins: Impact On In Vitro Fermentation And Methanemitigation From Total Mixed Ration, Manju Wadhwa, Prabh Kaur Sidhu, Mohinder Pal Singh Bakshi

Turkish Journal of Veterinary & Animal Sciences

Total mixed ration (TMR) containing roughage and concentrate mixture in a 65: 35 ratio on dry matter (DM) basis was supplemented with herbal feed additives [(HFAs); Acacia catechu (Katha), Areca catechu (Supari), and Acacia nilotica (Babul)] at 0-4% on DM basis to assess their impact on fermentation pattern and methane production by using in vitro gas production technique. Areca catechu had the highest (P < 0.01) concentration of condensed tannins (CTs), saponins, and vitamin C as compared to other HFAs. The net gas production (NGP), digestibility of NDF and true OM, and ME availability, partitioning factor (PF), volatile fatty acids (VFAs), and microbial biomass production were higher (P < 0.01) at 24 h as compared to t-half incubation, irrespective of type and level of HFAs supplemented. Acacia nilotica had an edge over Acacia catechu with respect to digestibility of nutrients and ME availability. VFAs production and efficiency of rumen fermentation was the highest from the Areca catechu-supplemented TMR. Irrespective of type of HFAs and incubation period, the digestibility of NDF and that of true OM were highest (P < 0.01) at the 1% level of supplementation, but depressed thereafter. Amongst HFAs-supplemented groups, VFA production and fermentation efficiency were highest at the 2% level. The results conclusively revealed that supplementing Areca catechu and Acacia nilotica at 2% of TMR (DM basis) inhibited the methane production, without affecting the fermentation pattern.

Turkish Journal of Veterinary & Animal Sciences

The objective of this study was to assess the changes in serum glucose, beta-hydroxybutyric acid (ß-HBA), and nonesterified fatty acid (NEFA) levels in Damascus dairy goats fed niacin (Nia) and methionine (Met) during late gestation and early postpartum period. A total of 75 dairy goats at 105th day of gestation were divided into 3 groups as control (no supplementation), Nia (20 g/kg Nia), and Met (2.5 g/kg Met) groups. The dietary treatments continued until parturition. Dairy goats fed dietary Nia had greater serum glucose levels on day 125 of gestation compared to the other dietary treatments (P < 0.05). On day 135 of pregnancy, serum glucose levels were higher in Met group than control group (P < 0.05). Serum ß-HBA levels decreased on days 135 and 145 in dairy goats fed Nia than those in control group. Dietary Nia and Met lowered serum ß-HBA levels on day 10 postpartum compared to control group (P < 0.05). Serum NEFA levels decreased (P < 0.05) on days 135 and 145 in dairy goats fed Nia supplemented ration than those in control group. Serum NEFA levels d 10 postpartum were different among the groups (P < 0.05). In conclusion, dietary Nia and Met supplementation improved serum glucose levels on day 125 of gestation while decreasing ß-HBA and NEFA levels during late gestation and early postpartum period in Damascus dairy goats under the conditions of present study.
