Background: Synthetic expanded polytetrafluorethylene (ePTFE) grafts are routinely used for vascular repair and reconstruction but prone to sustained bacterial infections. Investigational bioengineered human acellular vessels (HAVs) have shown clinical success and may confer lower susceptibility to infection. Here we directly compared the susceptibility of ePTFE grafts and HAV to bacterial ...
Feeding a Farrowing Sow: What Should we Consider? From feeder costs to feed palatability, here are some of the hot topics to think about when you are choosing the right sow feeding system for your farrowing rooms. Farrowing Feeding Methods Farrowing sows play an essential role in pig production since sow and litter performance can influence the swine industry’s next outcomes. Considering ...
A major concern for many producers who are evaluating the use of electronic sow feeding (ESF) in gestation barns is the impact on labor/staff and how a system that utilizes technology may increase either the time needed to manage group housing, or the quality of staff required to manage group housing, or both. As is the case with conventional European ESF’s, there is indeed a training ...
Creating the optimal environment for farrowing sows can help to minimize the challenges producers face when it comes to maintaining proper body condition and raising healthy piglets, as sow well-being will always be a constant concern within our industry. Improvements to sow feeding are a clear opportunity for improvement to body condition, overall health, increased productivity and overall herd ...
Not everyone will agree with my arguments in this article. However, I’m tired of hearing complaints about current sow mortality rates and general agreement that additional research is needed in gilt development; yet remain disappointed in the lack of tangible, practical strategies that producers can take home and implement at the ‘slat level’ to make meaningful changes in their ...
The effects of heat stress on lactating sows has been studied by several research institutions worldwide. We can look at primiparous (first parity) or multi-parous sows but the results are similar (Williams, 2009) For this discussion, let us look at farrowing room environment conditions of 68°F (desired) vs. 77°F (hot). The period that should be most scrutinized is the ambient ...
Nitinol, standard as form memory alloy, demonstrates a singular ability to recover its initial form when deformation through a reversible thermo-elastic section transformation, it permits form Memory Alloys to recover massive strains, either ad lib (pseudo elasticity) or through a rise in temperature (Shape Memory Effect). ...
Scientists in South East Asia have been measuring greenhouse gas (GHG) emissions from goats and cattle in a series of research projects investigating the effects of different feeding regimes. In each case, the eructed, or belched, emissions from each animal were measured with a portable FTIR gas analyzer from Gasmet Technologies. The research papers have been published by ‘Livestock ...
While buckets and powdered minerals are more convenient being offered ad lib, there is no guarantee that every animal is receiving their daily requirement, leading to variation in performance. ...
Survival, growth, emergence and reproduction were monitored during the life cycle of Chironomus riparius in the laboratory at five temperatures from 15 to 27 °C and two feeding diets (ad libitum and limiting). Data were analysed using an energy-based model. Survival was not affected. In ad libitum conditions, growth rate increased linearly with temperature as a consequence of quicker food ...
Abstract We present a bioenergetics-based approach to analyze the chronic effects and growth toxicity mode of action in tilapia Oreochromis mossambicus exposed to waterborne As and to predict fish growth under different exposure scenarios. 7-day exposure bioassays showed that tilapia accumulate As when exposed to waterborne As. We conducted growth bioassays to assess chronic As toxicity to ...
