Presence of Transcription Factor OCT4 Limits Interferon-tau Expression during the Pre-attachment Period in Sheep
Interferon-tau Transcription Gene regulation Implantation Sheep
2016/5/11
Interferon-tau (IFNT) is thought to be the conceptus protein that signals maternal recognition of pregnancy in ruminants. We and others have observed that OCT4 expression persists in the trophectoderm...

The effects of exogenous fibrolytic enzymes (EFE; a mixture of two preparations from Trichoderma spp., with predominant xylanase and β-glucanase activities, respectively) on colonization and digestion...
Low Ruminal pH Reduces Dietary Fiber Digestion via Reduced Microbial Attachment
Bacterial Attachment Fiber Digestion pH Fibrobacter succinogenes Ruminococcus flavefaciens Ruminocococcus albus
2016/4/25
In vitro rumen incubation studies were conducted to determine effects of initial pH on bacterial attachment and fiber digestion. Ruminal fluid pH was adjusted to 5.7, 6.2 and 6.7, and three major fibr...
