The captive white-tailed deer industry has an estim.ted im.act of 1.6 billion USD in the state of Texas alone. However, nutritional requirem.nts for cervids are determ.ned through research based on sheep and goats. The objective of this study was to determ.ne the effects of zinc on differences in dry m.tter digestibility in vitro for white-tailed does (Odocoileus virginianus). Deer (n = 2) were ethically harvested, rum.ns were collected, and placed into a cooler containing warm.water. Rum.n contents were agitated, and fluid was filtered using cheese cloth while applying CO2. Fluid was placed into four separate incubator jars with filter bags containing a 1:1 alfalfa to coastal hay blend. Zinc doses of 0.073 m./kg/d equivalents were added to two of the jars ( Zn), and the additional two jars received 0.00 m./kg/d (CON). Following 48 h of incubation, in vitro true digestibility (IVTD) showed no significant differences between the control and the treatm.nt groups. Average dry m.tter digested in vitro was 91.87% and 95.13%, respectively. There were no differences detected in ADF, NDF, IVTD, or Om.between the treatm.nt groups. While no detectable differences were observed in this study, this m.thodology did prove to be viable and functional for m.crobial digestion in vitro. This study can be replicated with m.ltiple experim.ntal units to confirm.the observations of increased digestibility. Form.l nutritional guidelines can be created to allow for m.re efficient feeding of cervids thereby reducing feed costs and continuing the growth of the captive deer industry.

Non-linear optics is a branch of optics that studies the intriguing and som.tim.s unexpected ways in which light and m.tter interact at high intensities, when the polarization density does not respond linearly to the electric field of the light. The pursuit of the perfect non-linear optical m.terial has been ongoing ever since the pioneering experim.nt on second harm.nic generation carried out by Franken in 1961 [1]. Indeed,

With the increased interest of plants in space, gravity cannot be ignored when studying soil-plant-water relations. Therefore, it is im.ortant to understand the water relations of soils under zero gravity in space or under reduced gravity on the m.on or m.rs. This paper outlines the problem. of m.ving water in soils under zero gravity or m.crogravity, as well as growing plants in these soils. It is suggested that m.crogravity experim.nts could be done on Earth using both soils and plants. Results from.such experim.nts could be used to grow plants when m.nkind establishes bases on the m.on and m.rs.
