Turkish Journal of Veterinary & Animal Sciences

The present study was conducted to compare the fertility of ewes, the survival rates, and the growth performance of lambs that were crossbred by mating German Black-Headed Mutton (GBM) rams with Kıvırcık ewes. The average lambing rates of the GBM × K(F1), Bandırma-I and Bandırma-II genotype, and Kıvırcık ewes were 80.00%, 75.73%, 76.78%, and 83.72%, respectively. The differences in lambing rates between the genotypes were significant (P < 0.01). The genotypes had a significant effect on litter size at birth, but not on fecundity. The differences in lambs' survival rates between the genotypes were significant (P < 0.05). The birth weight (BW), weaning weight (WW), and yearling live weight (YLW) of the lambs were 3.77 kg, 34.11 kg, and 43.71 kg for the GBM × K (F1); 3.74 kg, 32.98 kg, and 44.91 kg for the Bandırma-I; 3.73 kg, 33.18 kg, and 45.71 kg for the Bandırma-II; and 3.45 kg, 30.92 kg, and 42.22 kg for the Kıvırcık lambs. The results of this study showed that crossbreeding between the GBM and Kıvırcık breed did not significantly increase lamb production. However, crossbred lambs did not have significant survival problems when compared to native Kıvırcık lambs and had higher growth performance than purebred Kıvırcık lambs.

Double-Layer Mesh Hernioplasty For Repairing Umbilical Hernias In 10 Goats*, Jose M. Vilar, Juan A. Corbera, Giuseppe Spinella Jan 2011

Double-Layer Mesh Hernioplasty For Repairing Umbilical Hernias In 10 Goats*, Jose M. Vilar, Juan A. Corbera, Giuseppe Spinella

Turkish Journal of Veterinary & Animal Sciences

Umbilical hernias in goats are uncommon and can vary in their etiology and management. Hernioplasty can be done by closing the abdominal wall with a horizontal mattress pattern using absorbable sutures. However, larger defects (hernial ring size >3 cm) generally require the use of prosthetic materials that allow for a tension-free repair. In this study, 10 young female goats with umbilical hernias and hernial ring sizes ranging from 7-10 cm in width were treated using a double-layer polypropylene mesh. An ultrasonographic examination was performed to assess healing and connective tissue production.

The Increase Of Cd4+Cd25+ T Cells In The Peripheral Blood Of Pigs Persistently Infected With Porcine Reproductive And Respiratory Syndrome Virus, Jingwen Zeng, Danting He, Xin Guo, Xinna Ge, Hanchun Yang

Turkish Journal of Veterinary & Animal Sciences

Regulatory T lymphocytes (T-regs) may be involved in suppressing the host's immunity, which is important for viral clearance, and may therefore contribute to persistent viral infection. However, nothing is known regarding the situation of porcine T-regs during persistent infection with porcine reproductive and respiratory syndrome virus (PRRSV). This study, which used flow cytometry and real-time PCR, determined that the frequencies of CD4+CD25+ T-cells and porcine Forkhead/winged helix transcription factor (FoxP3) mRNA levels in peripheral blood significantly increased during PRRSV persistence, indicating that CD4+CD25+ T-regs might play an important role in PRRSV persistent infection. This study contributes to a better understanding …
