Right now, you are probably getting tired of hearing from me about new tick species and the diseases and potential allergies they vector to producers, livestock, and companion animals in Ohio that we have to worry about. I wrote an article for All About Grazing back in June of 2019 warning about the mammalian muscle allergy that can make you allergic to red meat from a Lone Star tick bite. My colleague Erika Lyon submitted an All About Grazing article introducing you to the Asian Longhorned Tick in January of 2019 and I submitted an article as a follow up to the Asian Longhorned tick in Ohio in July of 2020. Now we have a confirmed case of that invasive Continue reading

Supplement Energy to Ewes in Late Gestation

Dr. Benjamin Wenner, Assistant Professor, Department of Animal Sciences, The Ohio State University

As we approach the winter lambing season in Ohio, producers have a variety of approaches to feeding pregnant ewes. Those who believe underfeeding their ewe will decrease fetal size are partially correct (as addressed in the ASIA Sheep Production Handbook, 2002), but the likelihood of decreasing dystocia with underfeeding is nearly nil. In a 2007 review of lambing data, late gestation energy supplementation could account for increasing fetal weight by roughly ½ lb. (Gardner et al., 2007). Certainly, there are many other factors leading to dystocia that deserve consideration before a ½ lb. increase in lamb birth weight garners attention. Twinning alone can reduce birth weights (despite increasing ewe conceptus weight and energy requirement) and thus practices to achieve greater fertility in your breeding flock are a wiser pursuit than trying to nutritionally limit birth weights during gestation.
