Management Strategies In Farrowing House To Improve Piglet Pre-Weaning Survival And Growth, Ramon Muns Vila, Padet Tummaruk

The Thai Journal of Veterinary Medicine

Post-partum and lactation are the most complex periods in the swine production chain. Newborn pigs are highly vulnerable due to relatively low body weight at birth and physiological immaturity. Most of the management strategies performed in farrowing houses are oriented to ensure a proper level of colostrum intake by the piglets. Colostrum is essential as an energy source and to provide passive immunity to piglets. Different farrowing supervising protocols have been comprehensively investigated to reduce early mortality as well as to assist newborn piglets in obtaining an optimal amount of colostrum and milk. However, little is known of the benefits …

Rna Interference Targeting Glycoprotein D Inhibits Infectious Bovine Rhinotracheitis Virus Replication In Mdbk Cells, Lingling Song, Hui Zhang, Hongmei Wang, Peili Hou, Xianzhu Xia, Hongbin He

The Thai Journal of Veterinary Medicine

Infectious bovine rhinotracheitis (IBR) is an acute, febrile, contagious disease caused by infectious bovine rhinotracheitis virus (IBRV). IBRV vaccine is considered to be partially effective but not yet completely successful. Therefore, establishing a new antiviral approach is critical. RNA interference (RNAi) has been rapidly developed in recent years as an antiviral therapy for several viruses. This study showed that RNAi could suppress IBRV replication via knockdown of a virion glycoprotein. Two recombinant lentiviral vectors containing short hairpin RNAs (shRNAs) (H1-RNA-121, H1-RNA-304) against the glycoprotein gD of IBRV and a pcDNA3-gD vector containing a FLAG tag were constructed. pcDNA3-gD and the …

Evidence Of Kisspeptin Receptor Expression In Gnrh Neurons In The Preoptic Area And Arcuate Hypothalamic Nuclei In Cycling Buffaloes, Thuchadaporn Chaikhun-Marcou, Pongsiwa Sotthibandhu, Victoria Kyle, Shel Hwa Yeo, William Henry Colledge, Siriwat Suadsong

The Thai Journal of Veterinary Medicine

Our previous study reported the expression of kisspeptin in the preoptic area (POA) and arcuate nucleus (ARC) of the hypothalamus of cycling buffalo cows. In ruminants, POA and ARC are the main hypothalamic nuclei through which kisspeptin acts on the hypothalamic-pituitary-gonadal axis, due to their stimulation of gonadotropin releasing hormone (GnRH) secretion. In many species, kisspeptin activates GnRH neurons via its receptors (KISS1R or GPR54). The present study was designed to explore the expression of KISS1R by GnRH neurons in the POA and ARC hypothalamic nuclei in buffalo cow brains by double-labeling immunohistochemistry. In both the POA and ARC areas, …
