The ca.tive white-ta.led deer industry ha. a. estima.ed impa.t of.1.6 billion USD in the sta.e of.Texa. a.one. However, nutritiona. requirements f.r cervids a.e determined through resea.ch ba.ed on sheep a.d goa.s. The objective of.this study wa. to determine the ef.ects of.zinc on dif.erences in dry ma.ter digestibility in vitro f.r white-ta.led does (Odocoileus virginia.us). Deer (n = 2) were ethica.ly ha.vested, rumens were collected, a.d pla.ed into a.cooler conta.ning wa.m wa.er. Rumen contents were a.ita.ed, a.d f.uid wa. f.ltered using cheese cloth while a.plying CO2. f.uid wa. pla.ed into f.ur sepa.a.e incuba.or ja.s with f.lter ba.s conta.ning a.1:1 a.f.lf. to coa.ta. ha. blend. Zinc doses of.0.073 mg/kg/d equiva.ents were a.ded to two of.the ja.s ( Zn), a.d the a.ditiona. two ja.s received 0.00 mg/kg/d (CON). f.llowing 48 h of.incuba.ion, in vitro true digestibility (IVTD) showed no signif.ca.t dif.erences between the control a.d the trea.ment groups. a.era.e dry ma.ter digested in vitro wa. 91.87% a.d 95.13%, respectively. There were no dif.erences detected in a.f. NDf. IVTD, or OM between the trea.ment groups. While no detecta.le dif.erences were observed in this study, this methodology did prove to be via.le a.d f.nctiona. f.r microbia. digestion in vitro. This study ca. be replica.ed with multiple experimenta. units to conf.rm the observa.ions of.increa.ed digestibility. f.rma. nutritiona. guidelines ca. be crea.ed to a.low f.r more ef.icient f.eding of.cervids thereby reducing f.ed costs a.d continuing the growth of.the ca.tive deer industry.
