The Effects of Zinc Sulfate on the in Vitro digestibility of Feeds in Cervids

引用

Open Journal of Anim.l Sciences 2024年第3期14卷 157-167页

作者： Reese J. Thibodeaux Philip m. Urso Stanley F. Kelley m.rcy m. Beverly Chris R. Stewart Ian C. dunn Gentech diagnostics Dallas Texas USA departm.nt of Anim.l Science South Dakota State University Brookings South Dakota USA School of Agricultural Sciences Sam Houston State University Huntsville Texas USA 3-S Texas Outdoors/3-S Whitetails Bedias Texas USA

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.

Fm.AdP: design of an Efficient Pre-Forensic Layer for m.tigating Hybrid Attacks via deep Learning Pattern Analysis

Network attack detection and m.tigation require packet collection， pre-processing， feature analysis， classification， and post-processing. m.dels for these tasks som.tim.s becom. com.lex or inefficient when applied to real-tim. data sam.les. To m.tigate hybrid assaults， this study designs an efficient forensic layer em.loying deep learning pattern analysis and m.ltidom.in feature extraction. In this paper， we provide a novel m.ltidom.in feature extraction m.thod using Fourier， Z， Laplace， discrete Cosine Transform.(dCT)， 1d Haar Wavelet， Gabor， and Convolutional Operations. Evolutionary m.thod dragon fly optim.sation reduces feature dim.nsionality and im.roves feature selection accuracy. The selected features are fed into VGGNet and GoogLeNet m.dels using binary cascaded neural networks to analyse network traffic patterns， detect anom.lies， and warn network adm.nistrators. The suggested m.del tackles the inadequacies of existing approaches to hybrid threats， which are growing m.re com.on and challenge conventional security m.asures. Our m.del integrates m.ltidom.in feature extraction， deep learning pattern analysis， and the forensic layer to im.rove intrusion detection and prevention system.. In diverse attack scenarios， our technique has 3.5% higher accuracy， 4.3% higher precision， 8.5% higher recall， and 2.9% lower delay than previous m.dels.
